  In 3GPP (3rd Generation Partnership Project), the W-CDMA (Wideband Code Division Multiple Access) method has been standardized as a third generation cellular mobile communication method, and services have been started sequentially (for example, see Non-Patent Document 1). One of the W-CDMA systems is a frequency division duplex (FDD) spread spectrum system having a 5 MHz radio frequency bandwidth. Each radio physical channel is distinguished by code, multiplexed by code, and the same. It is transmitted with a radio frequency bandwidth.

  In the W-CDMA system, there are a radio link (hereinafter referred to as an uplink) from a mobile station to a base station and a radio link (hereinafter referred to as a downlink) from the base station to the mobile station. In uplink / downlink, SAP (Service Access Point) between Layer 3 and Layer 2 is a logical channel (Logical Channel), and Layer 1 is a transport channel (Transport Channel), In order to realize transmission of a port channel using an actual wireless transmission path, there is a physical channel (Physical Channel) defined as a transmission channel between layer 1 wireless nodes (base station and mobile station) (for example, Non-Patent Document 2).

  As a downlink physical channel of W-CDMA, a common pilot channel CPICH (Common Pilot Channel), a synchronization channel SCH (Synchronization Channel), a paging indicator channel PICH (Paging Indicator Channel), a first common control physical channel P-CCPCH (Primary) Common Control Physical Channel), Second Common Control Physical Channel S-CCPCH (Secondary Common Control Channel), Downlink Dedicated Physical Data Channel DPDCH (Dedicated Physical Data Channel), Downlink Dedicated Physical Channel (PC) edicated Physical Control Channel), acquisition indicator channel AICH (Acquisition Indicat Channel), and the like.

  As physical uplink uplink channels of W-CDMA, there are a physical random access channel PRACH (Physical Random Access Channel), an uplink dedicated physical data channel DPDCH, and an uplink dedicated physical control channel DPCCH.

  In the W-CDMA downlink, the first common control physical channel P-CCPCH has a transport channel broadcast channel BCH (Broadcast Channel), and the second common control physical channel S-CCPCH has a downlink access channel FACH (Forward). An Access Channel) and a paging channel PCH (Paging Channel) are included. The downlink dedicated physical data channel DPDCH includes a downlink dedicated channel DCH (Dedicated Channel) of the transport channel.

  In addition, a high speed downlink packet radio access HSDPA (High Speed Downlink Packet Access) (Non-patent Document 3) method in which a W-CDMA downlink is applied to high-speed packet communication has been standardized.

  High-speed physical downlink shared channel HS-PDSCH (High Speed Shared Linked Channel) and HS-DSCH related shared control channel HS-SCCH (HS-DSCH-related Shared Channel) are available as downlink physical channels of the HSDPA scheme.

  As an uplink physical channel of the HSDPA scheme, there is an HS-DSCH related uplink dedicated physical control channel HS-DPCCH (Dedicated Physical Control Channel HS-DSCH).

  In the HSDPA downlink, the high-speed physical downlink shared channel HS-PDSCH includes a transport channel high-speed downlink shared channel HS-DSCH (High Speed Downlink Shared Channel).

Next, an outline of main physical channels and transport channels of W-CDMA will be briefly described.
The common pilot channel CPICH is a downlink common channel, and there is one in each cell. Mainly, the downlink channel state estimation (channel estimation, channel estimation), mobile station cell selection (cell search, Cell Search). ), Used as a timing reference for other downlink physical channels in the same cell.
The synchronization channel SCH is a downlink common channel, one for each cell, and is used in the initial stage of mobile station cell search.

  The paging indicator channel PICH is a downlink common channel, exists in a pair with a paging channel PCH (Paging Channel) of a transport channel corresponding to the second common control physical channel S-CCPCH to which a paging signal is mapped, and moves. The presence / absence of incoming information of a voice call (CS: Circuit Switch) or a packet call (PS: Packet Switch) for each incoming call group which is a collection of stations is transmitted. When the mobile station belonging to the incoming call group #n is notified that there is an incoming call for the incoming call group #n on the paging indicator channel PICH, the corresponding radio frame mapped to the second common control physical channel S-CCPCH The paging channel PCH is received, and whether or not there is an incoming call is determined.

  The paging indicator channel PICH is a channel set for the purpose of reducing an intermittent reception (IR) ratio in order to improve battery saving of the mobile station. The paging indicator channel PICH transmits a short paging indicator PI (Paging Indicator) to the mobile stations belonging to the incoming call group #n to notify the presence / absence of an incoming call to the mobile station, and is in standby (idle mode). The mobile station normally receives only this paging indicator PI. The mobile station receives the paging channel PCH corresponding to the paging indicator PI only when notified by the paging indicator PI that there is an incoming call.

  Since the paging indicator PI is divided into a plurality of incoming groups #n and the incoming frequency per incoming group #n can be extremely low, only a short paging indicator PI is available for a mobile station in standby (idle mode). Can be received, and the frequency of receiving the paging signal of the long (large amount of information) paging channel PCH can be extremely low.

The downlink access channel FACH is a downlink common channel and is used for transmission of control information and user data. Here, the downlink access channel FACH is shared by a plurality of mobile stations and used for low-rate data transmission from an upper layer.

  The paging channel PCH is a downlink common channel, exists as a pair with the paging indicator channel PICH as described above, and is used for transmission of a paging signal. The paging signal includes a message such as a mobile station ID (UE identity), a core network ID (CN identity), a paging case, a broadcast information update notification, and a relocation registration notification.

  For the downlink / uplink dedicated physical data channel DPDCH and the downlink / uplink dedicated physical control channel DPCCH, in the downlink, the downlink dedicated physical data channel DPDCH and the downlink dedicated physical control channel DPCCH are time-multiplexed in time slots, and in the uplink, the uplink The dedicated physical data channel DPDCH and the uplink dedicated physical control channel DPCCH are mapped to the I phase and the Q phase, respectively. One or more downlink / uplink physical data channels DPDCH are allocated to the mobile station (spreading code multiplexing), and are used for data transmission from an upper layer. Only one downlink / uplink dedicated physical control channel DPCCH is allocated to the mobile station and is used for physical layer control.

  The acquisition indicator channel AICH is a downlink common channel and exists in a pair with the physical random access channel PRACH. Used for random access control of the physical random access channel PRACH.

  The physical random access channel PRACH is an uplink common channel to which a random access channel RACH, which is a transport channel, is mapped. Random access is applied and is used to send control information at the time of outgoing. It is also used for data transmission (mainly low rate) from higher layers.

Next, an outline of main physical channels and transport channels in the HSDPA system will be briefly described.
The high-speed physical downlink shared channel HS-PDSCH of the HSDPA system is a downlink shared channel, and is shared by a plurality of mobile stations. Each mobile station has a high-speed downlink shared channel HS-DSCH (High Speed Downlink Shared Channel). Is included. Used to transmit packet data addressed to each mobile station from the upper layer.

Each mobile station has information necessary for demodulation of the high-speed downlink shared channel HS-DSCH (mobile station). ID, modulation scheme, spreading code), information necessary for error correction decoding processing and hybrid automatic retransmission HARQ (Hybrid Automatic Repeat reQuest) processing is transmitted.

  HS-DSCH-related uplink dedicated physical control channel HS-DPCCH is an uplink dedicated control channel, and is received in correspondence with downlink quality information CQI (Channel Quality Indication) indicating the downlink radio channel condition and hybrid automatic retransmission HARQ. It is used for transmission of ACK / NACK (Acknowledgement / Negative Acknowledgments) as confirmation information.

  Meanwhile, the evolution of third generation radio access (Evolved Universal Terrestrial Radio Access (hereinafter referred to as EUTRA)) and the evolution of third generation radio access network (Evolved Universal Terrestrial Radio Access Network (hereinafter referred to as TR)) . An OFDM (Orthogonal Frequency Division Multiplexing) scheme has been proposed as a downlink of EUTRA. As the EUTRA technology, a technique such as an adaptive modulation and coding scheme (AMCS) based on adaptive radio link control (link adaptation, link adaptation) such as channel coding is applied to the OFDM scheme. Has been.

  In order to efficiently perform high-speed packet data transmission, the AMCS method is an error correction method, an error correction coding rate, a data modulation multi-value number, a time / frequency axis in accordance with the channel conditions of each mobile station. This is a method of switching radio transmission parameters (hereinafter referred to as AMC mode) such as a code spreading factor (SF) and a spread code multiplexing number. For example, with regard to data modulation, as the propagation path condition becomes better, switching from QPSK (Quadrature Phase Shift Keying) modulation to higher-efficiency multi-value modulation such as 8PSK modulation, 16QAM (Quadrature Amplitude Modulation) modulation, etc. The maximum throughput of the communication system can be increased.

  Regarding the arrangement of downlink physical channels and transport channels in the OFDM system, a method in which the physical control channel and the physical data channel are multiplexed in the same frequency band by spreading code multiplexing is proposed in the Spared-OFDM system (see, for example, Patent Document 1). ing. In the non-spread-OFDM scheme (for example, wireless LAN standard 802.16), time division multiplexed TDM (Time Division Multiplexing) is performed by using resources of the OFDM frequency axis (subcarrier) and time axis (OFDM symbol). In addition, frequency division multiplexing FDM (Frequency Division Multiplexing) or a method of multiplexing in time and frequency using a combination of TDM and FDM has been proposed.

Also, EUTRA / EUTRAN technical requirements (for example, see Non-Patent Document 4) have been proposed, and spectrum flexibility (spectrum flexibility) is required for integration and coexistence with existing 2G and 3G services. There is a need for support for spectrum allocations of spectrum (frequency bandwidths, eg, 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, 20 MHz).
JP 2001-237803 A JP 2004-197756 A 3GPP TS 25.211, V6.4.0 (2005-03), Physical channels and mapping of transport channels on to physical channels. http: // www. 3 gpp. org / ftp / Specs / html-info / 25-series. htm Keiji Tachikawa, “W-CDMA mobile communication system”, ISBN4-621-04894-5, P103, P115, etc. 3GPP TR (Technical Report) 25.858 and 3GPP HSDPA specification related documents. http: // www. 3 gpp. org / ftp / Specs / html-info / 25-series. htm 3GPP TR (Technical Report) 25.913, V2.1.0 (2005-05), Requirements for evolved Universal Terrestrial Radio Access (UTRA) and Universal Terrest U. http: // www. 3 gpp. org / ftp / Specs / html-info / 25913. htm

  However, in the conventional method, each physical channel is arranged in the entire allocated spectrum (for example, 5 MHz). For example, in the W-CDMA / HSDPA scheme, each physical channel is assigned to the entire spectrum (5 MHz) using a different spreading code. For this reason, it cannot be flexibly adapted to various different frequency bandwidths such as 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, and 20 MHz required for the technical requirements of EUTRA / EUTRAN.

  In addition, since the mobile station performs reception with a fixed frequency bandwidth, intermittent reception in standby (idle mode, inactive mode, etc.) minimizes the time interval of intermittent reception and achieves low power consumption. Does not consider changes in the received frequency bandwidth corresponding to a variety of different frequency bandwidths.

  The present invention has been made to solve the above-mentioned problems, and is a physical channel mapping method adapted to different frequency bandwidths (for example, 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, and 20 MHz), particularly packet paging.

  FIG. 1 is a diagram for explaining an example of the EUTRA channel configuration, and shows an example of the uplink / downlink channel configuration assumed for EUTRA based on the 3GPP proposal. As a downlink physical channel of EUTRA, a downlink pilot channel DPCH (Downlink Pilot Channel), a downlink synchronization channel DSCH (Downlink Synchronization Channel), a downlink common control channel DCCCH (Downlink Common Control Channel control), and a downlink common control channel DS (Downlink Shared Control Signaling Channel) and downlink shared data channel DSDCH (Downlink Shared Data Channel).

  In addition, as uplink physical channels of EUTRA, an uplink contention base channel UCBCH (Uplink Contention-based Channel) and an uplink scheduling channel USCH (Uplink Scheduling Channel) are configured.

Next, the outline of the downlink channel and the uplink channel of EUTRA will be briefly described. FIG. 2 is a diagram illustrating a correspondence relationship between EUTRA and W-CDMA / HSDPA uplink / downlink channels assumed based on the 3GPP proposal.
In the downlink of EUTRA, the downlink pilot channel DPCH includes a downlink common pilot channel DCPCH (Downlink Common Pilot Channel) and a downlink dedicated pilot channel DDPCH (Downlink Dedicated Pilot Channel).

  The downlink common pilot channel DCPCH corresponds to the pilot channel CPICH of the W-CDMA system, and is used for estimation of the downlink channel condition in the AMCS system, and for the channel loss measurement of cell search and uplink transmission power control. The downlink dedicated pilot channel DDPCH is transmitted to an individual mobile station from an antenna having a propagation path (directivity) different from that of a cell shared antenna such as an adaptive array antenna, or is common to the downlink for a mobile station with low reception quality. It can also be used for the purpose of reinforcing the pilot channel DCPCH.

The downlink synchronization channel DSCH corresponds to a W-CDMA synchronization channel SCH and is used for cell search of mobile stations, radio frames of OFDM signals, time slots, transmission timing intervals TTI (Transmission Timing Interval), and OFDM symbol timing synchronization. ing.
The downlink common control channel DCCCH is broadcast information corresponding to the first common control physical channel P-CCPCH, the second common control physical channel S-CCPCH, and the paging indicator channel PICH of the W-CDMA system (corresponding to the broadcast channel BCH), Common control information such as packet paging indicator PI information (equivalent to paging indicator channel PICH) indicating packet presence / absence, packet paging information corresponding to packet call (equivalent to paging channel PCH), downlink access information (equivalent to downlink access channel FACH), and the like. include.

  The downlink shared control signaling channel DSCSCH corresponds to the HS-DSCH related shared control channel HS-SCCH, the downlink dedicated control channel DPCCH, and the acquisition indicator AICH included in the high-speed physical downlink shared channel HS-PDSCH of the HSDPA scheme, Information shared by the stations and necessary for demodulation of the high-speed downlink shared channel HS-DSCH (modulation method, spreading code, etc.), information necessary for error correction decoding processing and HARQ processing, and radio resources (frequency, time) ) Is used to send scheduling information.

  The downlink shared data channel DSDCH corresponds to the high-speed downlink shared channel HS-DSCH and the downlink dedicated data channel DPDCH included in the high-speed physical downlink shared channel HS-PDSCH of the HSDPA method. Used for transmission.

  In the uplink, the uplink contention base channel UCBCH includes a fast access channel FACH (Fast Access Channel), a reserved channel RCH (Reservation Channel), and an uplink synchronization channel USCH (Uplink Synchronization Channel). This corresponds to a W-CDMA random access channel RACH (Radom Access Channel).

  The uplink scheduling channel USCH includes an uplink shared data channel USDCH (Uplink Shared Data Channel) and an uplink shared control signaling channel USSCH (Uplink Shared Control Signaling Channel). The uplink shared data channel USDCH corresponds to the W-CDMA uplink dedicated data channel DPDCH, and is shared by each mobile station and used for packet data transmission of each mobile station. The uplink shared control signaling channel USCSCH corresponds to the HS-DSCH related uplink dedicated physical control channel HS-DPCCH and dedicated control channel DPDCH of the HSDPA method, and is shared by each mobile station, and the downlink channel propagation path quality information of each mobile station It is used for transmission of feedback information such as CQI (Channel Quality Indicator) and HARQ, uplink pilot, and uplink channel control information.

Regarding EUTRA, the flow of outgoing and incoming packet calls of a mobile station assumed based on the proposal of 3GPP will be described.
First, FIG. 3 shows a state transition of a mobile station assumed based on the proposal of 3GPP. In the mobile station, after power-on (10), public mobile communication PLMN (Public Land Mobile Network) selection / reselection and cell selection are performed (11). The mobile station further receives location registration update and broadcast information (12), and transitions to the idle mode (Idle Mode) (13), which is a standby state. In the idle mode, cell selection / reselection is performed.

When there is a packet arrival (17) from the base station to the mobile station, the mobile station receives the packet paging indicator PI information indicating the presence or absence of the packet call and the packet paging information corresponding to the packet call, and performs the packet communication processing procedure. Then, the mode transits to the active mode (15) during packet communication, and packet data is transmitted and received. When there is no transmission / reception of packet data exceeding a timer (for example, Tinact time interval) provided in the mobile station or base station, the process returns to the idle mode (or referred to as inactive mode) (13). Cell selection / reselection is also performed in the active mode (15).
When there is a packet transmission (14) from the user, the packet communication is in progress through the reception of downlink access information (corresponding to downlink access channel FACH), transmission of uplink access information (corresponding to random access channel RACH), and the packet communication processing procedure ( Transition to 15).

Next, referring to FIG. 4, a flow chart for making and receiving a packet call of a mobile station assumed based on the proposal of 3GPP will be described.
In the idle mode (step S1), the reception unit of the mobile station is in an intermittent reception state. Then, the mobile station determines whether or not there is a packet transmission (packet transmission operation by the user) (step S2), and further checks for a packet arrival (packet arrival of the incoming call group #n) (step S4).

  The packet paging indicator PI indicating the packet arrival of the packet arrival group #n to which the own station belongs is detected by reception of the packet paging indicator PI information indicating the presence / absence of the packet call during the period when the reception unit is ON during the intermittent reception in the idle mode. If not, the mobile station turns off the reception unit again, enters the sleep state, and keeps the power consumption of the mobile station low within a certain period.

  In addition, when there is a packet arrival from the base station during the period when the reception unit is ON during intermittent reception in the idle mode, the packet paging indicator PI information of the packet arrival group #n to which the own station belongs in the packet paging indicator PI information, and the packet A paging signal included in the packet paging information corresponding to the call is transmitted from the base station to the mobile station (step S3). While the receiving unit is on, the mobile station detects the presence of a packet arrival by receiving the packet paging indicator PI information of the packet arrival group #n to which the mobile station belongs (YES in step S4). Here, when the cell / public mobile communication network PLMN is updated, the mobile station performs relocation registration.

  When the mobile station detects a paging signal by receiving packet paging information (YES in step S5), the mobile station transits to an active mode in which packet communication is performed through a packet communication processing procedure (step S6) (step S7).

  In step S2, if there is a packet transmission operation by the user to the mobile station (YES in step S2), it is determined that there is packet transmission, and the mobile station goes through a packet communication processing procedure (step S6). Transition to the active mode (step S7) for performing packet communication.

  Further, in packet communication processing procedures (step S6) such as packet call setup, downlink access information included in the downlink common control channel DCCCH corresponding to the downlink access channel FACH in the W-CDMA scheme, and randomness in the W-CDMA scheme. Uplink access information included in the uplink contention base channel UCBCH corresponding to the access channel RACH can be used.

  The receiver signal processing procedure (the operation period) during the ON / OFF period of the receiver in the idle mode (step S1) is referred to as “standby procedure (period)”. The standby procedure (period) specifically includes a procedure for cell arrival judgment by cell search, packet transmission judgment (step S2), and check of packet paging indicator PI information of the incoming call group #n to which the own station belongs (step S4). ing.

  Reception unit in the on period of the reception unit from the reception of packet paging information (step S5) to the start of packet communication in the active mode (step S7), or from the packet transmission determination (step S2) to the start of packet communication in the active mode (step S7) The signal processing procedure (the operation period) is referred to as “connection procedure (period)”. Specifically, in the connection procedure (period), the center frequency shift, the paging signal (for example, mobile station ID, core network ID, paging case, etc.) included in the packet paging information are checked (step S5), and the packet communication processing procedure (step) S6) is included.

  The mobile station checks the packet paging indicator PI information of the packet arrival group #n to which the mobile station belongs by intermittent reception in the idle mode (step S1) (step S4), and the packet reception group #n of the mobile station to which the mobile station belongs. If it is determined that the mobile station group has an incoming packet, the paging signal in the packet paging information is checked (step S5). Here, when the paging signal of the own station is not detected, it is determined that the packet has arrived at another mobile station, and the process returns to the idle mode (step S1). That is, the process shifts from the standby procedure (period) to the connection procedure (period), and returns to the standby procedure (period) again when it is not an incoming call of the own station.

  FIG. 5 is a diagram illustrating a configuration example of a downlink radio frame assumed for EUTRA based on the proposal of 3GPP. The downlink radio frame is configured in two dimensions by Chunk, which is a cluster of a plurality of subcarriers on the frequency axis, and a transmission time interval TTI on the time axis. Chunk is composed of a group of several sub-carriers. For example, on the frequency axis, when the entire downlink spectrum (downlink frequency bandwidth) B5 is 20 MHz, the Chunk frequency bandwidth Bch is 1.25 MHz, and the subcarrier frequency bandwidth Bsc is 12.5 kHz, the downlink Then, 16 Chunks, one Chunk includes 100 subcarriers, and 1600 subcarriers in total. On the time axis, when one radio frame is 10 ms and TTI is 0.5 ms, 20 TTIs are included.

  In other words, in the above example, one radio frame includes 16 Chunks and 20 TTIs, and one TTI includes a plurality of OFDM symbol lengths (Ts). Therefore, in this example, the minimum radio resource unit that can be used by the mobile station is configured by one Chunk (100 subcarriers) and one TTI (0.5 ms). Further, one Chunk radio resource may be further divided. TTI may be 0.67 ms, 0.625 ms, or the like.

  As shown in FIG. 5, the downlink common pilot channel DCPCH is mapped to the head of each TTI, and the downlink dedicated pilot channel DDPCH is determined according to the antenna usage status of the base station or the propagation path status of the mobile station. It is mapped to the appropriate location of one TTI (eg, mapped to the center of the TTI).

  The downlink common control channel DCCCH and the downlink synchronization channel DSCH are mapped to the TTI at the head of the radio frame. By mapping these to the TTI at the head of the radio frame, if the mobile station receives only the radio frame head TTI or several OFDM symbol lengths (Ts) within the radio frame head TTI when the mobile station is in the idle mode, the cell It is possible to perform search and timing synchronization and receive downlink control information such as broadcast information, packet paging indicator PI information, and packet paging information.

In the idle mode, the mobile station operates with intermittent reception.
FIG. 6 is a diagram conceptually illustrating the intermittent reception operation when the mobile station is in the idle mode. Here, FIG. 6 (A) shows the same diagram as the structure of the downlink radio frame assumed based on the 3GPP proposal in FIG. 6 (B).

As shown in FIG. 6, as the intermittent operation when the mobile station is in the idle mode, for example, intermittent operation 1 and intermittent operation 2 can be cited.
The intermittent operation 1 is an intermittent reception method in which the receiving unit is turned on during the TTI1 period at the head of the frame and the reception is turned off during other periods. In the intermittent operation 2, the receiving unit turns on the period (several OFDM symbols Ts) of the downlink common pilot channel DCPCH, the downlink common control channel DCCCH, the downlink shared signaling channel DSCSCH, and the downlink synchronization channel DSCH of the TTI 1 at the head of the frame. This is an intermittent reception method in which reception of other periods is turned off.

  Similarly to the downlink common pilot CPICH, the downlink shared control signaling channel DSCSCH is mapped to the head part of each TTI. Even if the mobile station is in packet communication, if there is no packet data addressed to itself in each TTI, intermittent reception is possible in which only the downlink shared control signaling channel DSCSCH is received.

  In FIG. 5, the downlink pilot channel DPCH (downlink common pilot channel DCPCH and downlink dedicated pilot channel DDPCH), the downlink common control channel DCCCH, the downlink shared control signaling channel DSCSCH, and the downlink synchronization channel DSCH are frequency axes. Although it is shown that the upper subcarriers are continuously mapped, the subcarriers may be mapped intermittently by thinning.

  FIG. 7 is a diagram illustrating another configuration example of a downlink radio frame assumed for EUTRA based on the proposal of 3GPP. For example, as shown in FIG. 7, instead of the configuration of FIG. 5, the downlink common pilot channel DCPCH, the downlink common control channel DCCCH, and the downlink shared control signaling channel DSCSCH may be alternately arranged in subcarriers.

Each of the above downlink channels shows an example of TDM over the entire downlink frequency band, but may be a combination of CDM (Code Division Multiplexing), FDM, and TDM / FDM.
Each downlink channel indicates one OFDM symbol length (Ts), but a plurality of OFDM symbol lengths (Ts) may be used depending on the amount of information.

  The downlink shared data channel DSDCH transmits packet data addressed to each mobile station based on the AMCS scheme. As an example, as shown in FIG. 1, the mobile stations MS1, MS2, and MS3 are assigned according to the propagation path status of each mobile station.

8 and 9 are diagrams showing configuration examples of a base station and a mobile station related to the present invention, respectively.
In FIG. 8, a base station 100 includes an antenna unit 101, a radio unit 102, a demodulation unit 103, an uplink channel estimation unit 104, a control data extraction unit 105, a channel decoding unit 106, a channel coding unit 107, and a control data insertion unit 108. , An OFDM modulation unit 109, and a scheduling unit 110.

  In FIG. 9, the mobile station 200 includes an antenna unit 201, a radio unit 202, an OFDM demodulation unit 203, a downlink channel estimation unit 204, a control data extraction unit 205, a channel decoding unit 206, a channel coding unit 207, and control data insertion. The unit 208, the modulation unit 209, and the control unit 210 are configured.

The operation principle of the base station 100 and the mobile station 200 assumed based on the proposal of 3GPP will be briefly described with reference to FIGS.
In base station 100, first, when base station 100 receives packet data addressed to mobile station 200 from an RNC (Radio Network Control, not shown), the packet data is stored in a base station transmission data buffer (not shown). To do. The downlink transmission data from the transmission data buffer is input to the channel coding unit 107, and the channel coding unit 107 outputs the downlink AMC mode and the downlink mobile station allocation information (downlink scheduling information) that are output signals of the scheduling unit 110. Link AMC information is input, and downlink transmission data is encoded using an AMC mode (for example, turbo code, coding rate 2/3) defined by the downlink AMC information, and the output is control data. Input to the insertion unit 108.

The downlink control data includes control data for the downlink pilot channel DPCH, the downlink common control channel DCCCH, and the downlink synchronization channel DSCH. Downlink control data is input to the control data insertion unit 108, and control data mapping of the downlink common control channel DCCCH (downlink access channel FACH, paging channel PCH, paging indicator channel PICH and broadcast channel BCH) shown in FIG. 1 is performed. Is called.
On the other hand, downlink AMC information (AMC mode, downlink scheduling information, etc.) determined by the scheduling unit 110 is input to the control data insertion unit 108, and control data mapping of the downlink shared control signaling channel DSCSCH is performed.

  The output of the control data insertion unit 108 to which the downlink common control channel DCCCH, the downlink shared control signaling channel DSCSCH, and the downlink shared data channel DSDCH are mapped is sent to the OFDM modulation unit 109. The OFDM modulation unit 109 multiplies data modulation, serial / parallel conversion of the input signal, spreading code and scrambling code, performs OFDM signal processing such as IFFT (Inverse Discrete Fourier Transform) conversion, CP (Cyclic Prefix) insertion, and filtering. Generate an OFDM signal. Further, the OFDM modulation unit 109 receives the downlink AMC information from the scheduling unit 110 and controls data modulation (for example, 16QAM) of each subcarrier. Then, the radio frame shown in FIG. 5 is generated, converted into an RF (Radio Frequency) frequency band by a transmission circuit of the radio unit, and a downlink signal is transmitted from the antenna unit 101.

  On the other hand, an uplink signal transmitted from the mobile station 200 is received by the antenna unit 101, converted from an RF frequency to IF (Intermediate Frequency) or directly into a baseband by a reception circuit of the radio unit, and input to the demodulation unit 103. . Uplink signals use OFDM signals, MC-CDMA (Multi-Carler-CDMA) signals, or single carrier SC signals for reducing PAPR, VSCRF-CDMA (Variable Spreading and Chip Repetition Factors-CDMA) signals. (For example, refer to Patent Document 2 (Japanese Patent Laid-Open No. 2004-197756, “Mobile Station, Base Station, Wireless Transmission Program, and Wireless Transmission Method”).

  Uplink channel estimation section 104 estimates the uplink channel quality of each individual mobile station using uplink pilot channel UPCH, and calculates uplink channel quality information CQI. The calculated uplink CQI information is input to the scheduling unit 110. Then, uplink AMC information such as uplink AMC mode and uplink scheduling information is input to the control data insertion unit 108, mapped to the downlink shared control signaling channel DSCSCH, and transmitted to the corresponding mobile station 200.

  The corresponding mobile station 200 transmits packet data according to the determined uplink AMC mode and uplink scheduling information in accordance with the uplink AMC information output from the scheduling unit 110. Then, the uplink signal of the packet data is input to the demodulation unit 103 and the channel decoding unit 106. On the other hand, uplink AMC information that is an output of the scheduling unit 110 is input to the demodulation unit and the channel decoding unit 106, and uplink signal demodulation (for example, QPSK) and decoding processing (for example, convolutional code, code, etc.) according to this information Conversion rate 2/3).

  The control data extraction unit 105 extracts control information of the uplink contention base channel UCBCH and the uplink shared control signaling channel USCSCH. Further, the control data extraction unit 105 extracts the downlink channel channel quality information CQI of the mobile station 200 transmitted via the uplink shared control signaling channel USCSCH, and inputs it to the scheduling unit 110 to generate downlink AMC information. .

  The scheduling unit 110 receives uplink CQI information from the uplink channel estimation unit 104, receives downlink CQI information fed back from the mobile station 200 from the control data extraction unit 105, and further receives a base station control unit (not shown). 1), downlink / uplink transmission data buffer information, uplink / downlink QoS (Quality of Service) information, various service class information, mobile station class information, and the like of each mobile station are input. Then, the scheduling unit 110 combines the input information, generates uplink / downlink AMC information according to the selected scheduling algorithm, and outputs it to each unit shown in FIG.

  Next, in the mobile station 200, the downlink OFDM signal is first received by the antenna unit 201, converted from the RF frequency to IF or directly to the baseband by the reception circuit of the wireless unit 202, and input to the OFDM demodulation unit 203. The downlink channel estimator 204 uses the downlink pilot channel DPCH (using the downlink common pilot channel DCPCH, the downlink dedicated pilot channel DDPCH, or a combination of both), and the individual downlink of each mobile station. Channel propagation path quality is estimated, and downlink propagation path quality information CQI is calculated. The calculated downlink CQI information is input to the control data insertion unit 208, mapped to the uplink shared control signaling channel USCSCH, and transmitted to the base station 100.

  The OFDM demodulator 203 multiplies the input signal by CP (Cyclic Prefix), FFT (Discrete Fourier Transform) conversion, spreading code and scrambling code, and performs OFDM signal demodulation processing such as parallel / serial conversion, data demodulation, and filtering. The demodulated data is generated and input to the control data extraction unit 205.

  The control data extraction unit 205 extracts downlink channel information other than the downlink shared data channel DSDCH. Downlink AMC information such as downlink AMC mode and downlink scheduling information mapped to the downlink shared control signaling channel DSCSCH is extracted and output to the OFDM demodulator 203 and the channel decoder 206. Also, uplink AMC information such as uplink AMC mode and uplink scheduling information mapped to the downlink shared control signaling channel DSCSCH is extracted and output to the modulation unit 209 and the channel coding unit 207.

  The OFDM demodulator 203 demodulates subcarriers using an AMC mode (for example, 16QAM) defined by downlink AMC information. The channel decoding unit uses the AMC mode defined by the downlink AMC information (for example, turbo code, coding rate 2/3) and packet data addressed to the own station mapped to the downlink shared data channel DSDCH. Is decrypted.

  The channel coding unit 207 receives uplink transmission data, which is individual packet data of the mobile station 200, and downlink AMC information (for example, convolutional code, coding rate 2 / output) output from the control data extraction unit 205. 3) is used for encoding and output to the control data insertion unit 208.

  The control data insertion unit 208 maps the downlink CQI information from the downlink channel estimation unit 204 to the uplink shared control signaling channel USCSCH included in the uplink scheduling channel USCH, and the uplink contention base channel UCBCH and the uplink scheduling channel USCH. Are mapped to the uplink transmission signal.

  Modulation section 209 performs data modulation using downlink AMC information (for example, QPSK) output from control data extraction section 205, and outputs the result to the transmission circuit of radio section 202. The modulation of the uplink signal may use an OFDM signal, an MC-CDMA signal, or a single carrier SC signal or a VSCRF-CDMA signal to reduce PAPR.

The signal is converted into an RF frequency band by the transmission circuit of the wireless unit 202 and an uplink signal is transmitted from the antenna unit 201. The wireless unit 202 includes IF and RF filters corresponding to the different frequency bandwidths (for example, 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, and 20 MHz).
The control unit 210 performs overall control of the mobile station 200 and controls the radio unit 202 and the baseband signal processing unit 211 by mapping downlink control information. For example, in the idle mode, the control unit 210 performs intermittent reception control of the mobile station 200. Do.

(First embodiment)
FIG. 10 is a diagram for explaining the first embodiment of the present invention. In the first embodiment, one of the downlink common control channel mapping methods assumed based on the proposal of 3GPP for EUTRA, broadcast information (corresponding to broadcast channel BCH of W-CDMA system) and presence / absence of packet call Paging indicator PI information (corresponding to W-CDMA paging indicator channel PICH) mapping method, and mobile station common control information receiving method corresponding to the broadcast information and packet paging indicator PI information mapping method To do.

As described above, as EUTRA / EUTRAN technical requirements, spectrum flexibility is required for fusion and coexistence with existing 2G and 3G services, and different frequency bandwidths (eg, 1.25 MHz, 2.5 MHz, Support for frequency allocation for 5 MHz, 10 MHz, and 20 MHz) is required.
Further, in the EUTRA / EUTRAN service, mobile stations having various frequency bandwidths are accommodated in the frequency bandwidths allocated to mobile communication carriers, and services for mobile stations having different frequency bandwidths are required. For example, with a frequency bandwidth of 20 MHz, mobile stations having different operating frequency bandwidths of 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, and 20 MHz are accommodated, standby in different frequency bandwidths, packet transmission / reception procedure processing, Packet data communication etc. need to operate normally. In addition, a mobile station having a wide frequency bandwidth (for example, 20 MHz) is required to have a standby time similar to or similar to a narrow frequency bandwidth (for example, 1.25 MHz).

  FIG. 10 shows a method of mapping the common control information included in the downlink common control channel by expanding the portion of the downlink common control channel DCCCH shown in FIG. In FIG. 10, B1, B2, B3, B4, and B5 indicate frequency bandwidths of 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, and 20 MHz, respectively. Here, a set of mobile stations corresponding to different frequency bandwidths is defined as a Bn (n = 1, 2,...) Mobile station class.

As shown in FIG. 5 or FIG. 7, the time width of the downlink common control channel DCCCH is Tdccch, and one Tdccch radio resource is used (when FDM method is adopted) or one or more (when TDM / FDM is adopted). Of OFDM symbols.
5 and 10 show a case where TDM is employed. Here, as a method for mapping the common control information, in the radio resources occupying the minimum frequency bandwidth B1 and the Tdccch time, all the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are used. Broadcast information and packet paging indicator PI information corresponding to the mobile station are mapped.

  Specifically, as shown in FIG. 10, broadcast information is mapped to area 1 and packet paging indicator PI information is mapped to area 2. Thus, by mapping the broadcast information and packet paging indicator PI information of all mobile stations of each mobile station class including the maximum frequency bandwidth B5 to the minimum frequency bandwidth B1, Bn (n including the maximum frequency bandwidth Bn (n = 1, 2, 3, 4, 5) All mobile stations in the mobile station class can receive broadcast information and packet paging indicator PI information through the minimum frequency bandwidth B1.

  That is, as shown in the packet transmission / reception flowchart of the mobile station in FIG. 4, all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth The standby procedure (period) can be normally operated through the bandwidth (for example, B1).

  Here, as a mapping method of the common control information, all the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are included in the radio resources occupying the frequency bandwidth of B1 and the Tdccch time. Since broadcast information corresponding to the mobile station and common control information of the packet paging indicator PI information are mapped, all of the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are mapped. The mobile station controls the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the minimum frequency bandwidth B1, and controls common control information necessary for the standby procedure (period), that is, broadcast information and packet paging indicator PI information. Can be received.

  FIG. 11 is an example illustrating a common control information reception method of a mobile station having the maximum frequency bandwidth B5 corresponding to the common control information mapping method. In FIG. 11, T1, T3, and T7 of the time intervals in which the mobile station power consumption is high are during the reception unit on period during intermittent reception of the standby procedure (period), and T5 is the period during which the reception unit is on during the connection procedure (period) The time intervals T2, T4, and T6 indicate that the receiving unit is off during intermittent reception.

The mobile station of the mobile station class with the maximum frequency bandwidth B5 controls the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the minimum frequency bandwidth B1, and common control information necessary for the standby procedure (period) That is, broadcast information and packet paging indicator PI information can be received. Then, in the connection procedure (period) for transitioning to the active mode based on the reception of packet paging information or the packet transmission determination, the control is performed by expanding the maximum frequency bandwidth B5.
In this way, all mobile stations perform intermittent reception with the minimum frequency bandwidth B1, and the power consumption of the standby procedure (period) in the idle mode can be minimized.

  In the mobile station common control information reception example of FIG. 11, when the connection procedure (period) of T5 is in the active mode, but there is no packet data over the Tinact time interval, the process returns to the idle mode standby procedure (period) again. The mobile station class mobile station having the maximum frequency bandwidth B5 again performs control according to the minimum frequency bandwidth B1 with respect to the reception frequency bandwidth, the number of IFFT points, the operation clock, and the like.

  FIG. 12 is an example for explaining a common control information reception method of a mobile station having the maximum frequency bandwidth B4 corresponding to the common control information mapping method. Since the frequency bandwidth B4 is smaller than the maximum frequency bandwidth B5, the connection procedure (period) of T5 shows a state in which the center frequency is shifted by the instruction of the base station and / or the calculation of the mobile station.

  In order to realize the above operation, the control data insertion unit 108 of the base station 100 shown in FIG. 8 includes common control information mapping means for mapping the downlink common control information to the common control channel DCCCH as shown in FIG. I have. In addition, the control data extraction unit 205 of the mobile station 200 shown in FIG. 9 includes common control information receiving means for extracting the common control information from the common control channel DCCCH as shown in FIG.

  11 and 12, T2 and T4 correspond to one radio frame unit, but may correspond to one or more radio frame units. T1, T3, and T7 may correspond to different lengths, TTI units, OFDM symbol units, or a plurality thereof.

As described above, the broadcast information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth and the common control information of the packet paging indicator PI information are minimized. Mapping to the frequency bandwidth B1 is a feature of the first embodiment.
According to the first embodiment, all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth operate with the minimum frequency bandwidth B1, and the standby procedure ( (Minimum standby power consumption), miniaturization of mobile stations, and long standby time requirements.

(Second Embodiment)
As described above, EUTRA / EUTRAN technical requirements require spectrum flexibility and support for frequency allocation for different frequency bandwidths (eg, 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, 20 MHz). ing.
In this embodiment, the EUTRA uplink / downlink channel configuration, the mobile station packet call outgoing / incoming flow chart, the downlink radio frame configuration, and the base station and mobile station configurations are the same as in the first embodiment. Therefore, the repeated explanation is omitted.

  FIG. 13 is a diagram for explaining a second embodiment of the present invention. In the second embodiment, similar to the first embodiment, one of the downlink common control channel mapping methods assumed based on the 3GPP proposal for EUTRA, broadcast information (W-CDMA system broadcast). This corresponds to a mapping method of packet paging indicator PI information (corresponding to a paging indicator channel PICH in the W-CDMA system) indicating the presence / absence of a packet call and a mapping method of the broadcast information and packet paging indicator PI information. A common control information reception method for mobile stations is proposed.

Broadcast information and packet paging indicator PI information, which are downlink common control information, are used in an idle mode that is a standby procedure (period), and the amount of information does not depend on the number of mobile stations accommodated in radio resources. do not do. In addition, the amount of information is small compared to downlink access information and packet paging information.
In the first embodiment, the broadcast information and packet paging indicator PI information of all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are stored in the minimum frequency band. Although a method of mapping to the width B1 has been proposed, since the minimum frequency bandwidth B1 of the system is used, it is easily affected by frequency selective fading. In addition, when the reception level fluctuation within the minimum frequency bandwidth B1 (for example, 1.25 MHz) is severe, the broadcast information and packet paging indicator PI information may not be received due to reception quality deterioration.

  In this embodiment, as shown in FIG. 13 (A), the downlink common control channel DCCCH part shown in FIG. 5 is expanded and the common control information included in the downlink common control channel is mapped. As a common control information mapping method, radio resources of maximum frequency bandwidth B5 and Tdccch time are used for all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth. Corresponding broadcast information and paging indicator PI information are copied to the Bn frequency bandwidth and distributed and mapped.

Specifically, as shown in FIG. 13A, the area 1 to which the broadcast information shown in the first embodiment is mapped and the area 2 to which the packet paging indicator PI information is mapped are defined as an area 21. Then, the area 21 is divided into two parts, and the divided broadcast information and packet paging indicator PI information are copied to the area 22 and the area 23 within the frequency bandwidth of B4-B3 (see FIG. 13B). ).
The broadcast information and the packet paging indicator PI information as described above are not limited to each area within the B4-B3 frequency bandwidth, but within all the Bn frequency bands (that is, Bn-Bm (n, m> 1). Copy to nm = 1).

FIG. 13B shows a state in which broadcast information and packet paging indicator PI information are copied to the frequency bandwidth Bn (n = 1, 2, 3, 4, 5).
Here, the broadcast information and packet paging indicator PI information of all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are used as the frequency bands of the respective Bn mobile station classes. By mapping to Bn-Bm (n, m>1; nm = 1), mobile stations of each Bn mobile station class receive broadcast information and packet paging indicator PI information through the minimum frequency bandwidth B1. be able to.

  In the present embodiment, as the reception quality deteriorates, the broadcast information and packet paging indicator PI copied by the frequency bandwidth Bn of the Bn mobile station class or the frequency bandwidth of B1, B2,. Information can be received. Here, by receiving multiple copy information in different frequency bandwidths, a frequency diversity effect can be obtained and reception quality can be improved. That is, as shown in the packet transmission / reception flowchart of the mobile station in FIG. 4, all the mobile stations of the Bn mobile station class improve the reception quality through each frequency bandwidth and operate the standby procedure (period) normally. be able to.

  As described above, the common control information of the broadcast information and the packet paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth, It is a feature of the second embodiment that mapping (copying) to the frequency bandwidth of Bn (to each frequency bandwidth including Bn and below Bn).

  Here, as a mapping method of the common control information, all the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are included in the radio resources occupying the maximum frequency bandwidth and the Tdccch time. Since the broadcast control information corresponding to the mobile station and the common control information of the packet paging indicator PI information are mapped (copied) to the frequency bandwidth of Bn, all mobile stations of the Bn mobile station class in the case of reception quality deterioration. Receives the broadcast information and the packet paging indicator PI information with the frequency bandwidth Bn of the Bn mobile station class or sequentially expanding the frequency bandwidth of B1, B2,..., Bn, and receives them by the frequency diversity effect. Improve quality.

  FIG. 14 is a diagram for explaining another example of the common control information reception method of the mobile station corresponding to the common control information mapping method. In FIG. 14, mobile station power consumption T1 and T3 indicate that the receiver is on during intermittent reception of the standby procedure (period), and T5 indicates that the receiver is on during the connection procedure (period). Indicates a period during which the receiving unit is turned off during intermittent reception. Here, T2 and T4 correspond to one radio frame unit, but may correspond to one or more radio frame units. T1 and T3 may correspond to different lengths, TTI units, OFDM symbol units, or a plurality thereof.

Mobile stations of the mobile station class having the maximum frequency bandwidth Bn (n = 1, 2, 3, 4, 5) control the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the minimum frequency bandwidth B1. And common control information necessary for the standby procedure (period), that is, broadcast information and packet paging indicator PI information can be received. In this case, when the reception quality is deteriorated (for example, during the T1 period), the mobile station of the Bn mobile station class sequentially increases the frequency bandwidth of Bn, or the frequency bandwidth of B1, B2,. T3 of FIG. 4 shows that the data is being received with the frequency bandwidth of B4), and the received broadcast information and packet paging indicator PI information are received, and the reception quality is improved by the frequency diversity effect. Then, in the connection procedure (period) for transitioning to the active mode based on the reception of packet paging information or the determination of transmission, control is performed by expanding to the maximum frequency bandwidth Bn.
In this way, all mobile stations perform intermittent reception with the minimum frequency bandwidth B1, and the power consumption of the standby procedure (period) in the idle mode can be minimized.

  According to the second embodiment, all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth operate with the minimum frequency bandwidth, and the reception quality deteriorates. In this case, the frequency bandwidth of the Bn mobile station class or the frequency bandwidths of B1, B2,..., Bn are sequentially widened to realize low standby power consumption in the standby procedure (period), thereby reducing the size and length of the mobile station. A request for standby time can be realized.

(Third embodiment)
As described above, EUTRA / EUTRAN technical requirements require spectrum flexibility and support for frequency allocation for different frequency bandwidths (eg, 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, 20 MHz). ing.
In this embodiment, the EUTRA uplink / downlink channel configuration, the mobile station packet call outgoing / incoming flow chart, the downlink radio frame configuration, and the base station and mobile station configurations are the same as in the first embodiment. Therefore, the repeated explanation is omitted.

  FIG. 15 is a diagram for explaining a third embodiment of the present invention. In the third embodiment, as in the first and second embodiments, one of the downlink common control channel mapping methods assumed based on the 3GPP proposal for EUTRA, broadcast information (W-CDMA) Mapping paging indicator PI information (corresponding to W-CDMA paging indicator channel PICH) indicating the presence / absence of a packet call, and mapping method of the broadcasting information and packet paging indicator PI information We propose a common control information reception method for mobile stations.

  As described above, broadcast information and packet paging indicator PI information, which are downlink common control information, are used in an idle mode that is a standby procedure (period), and do not depend on the number of mobile stations accommodated in radio resources, The amount of information is almost unchanged. In addition, the amount of information is small compared to downlink access information and packet paging information.

  In the first embodiment, the broadcast information and packet paging indicator PI information of all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are the minimum frequency band. Although a method of mapping to the width B1 has been proposed, since the minimum frequency bandwidth of the system is used, it is susceptible to frequency selective fading. Also, when reception level fluctuations within the minimum frequency bandwidth are severe, there are cases where broadcast information and packet paging indicator PI information cannot be received due to reception quality degradation.

  Further, in the radio resource occupying the maximum frequency bandwidth B5 and the Tdccch time as in the second embodiment, all of the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are used. The broadcast information and the packet paging indicator PI information corresponding to the mobile stations of the above have been copied to the Bn frequency bandwidth and distributed and mapped. However, the information amount of the broadcast information and the packet paging indicator PI information is small. In some cases, radio resources cannot be used sufficiently.

  In this embodiment, as shown in FIG. 15A, the portion of the downlink common control channel DCCCH shown in FIG. 5 is expanded and the common control information included in the downlink common control channel is mapped. As a common control information mapping method of the present embodiment, in radio resources occupying the maximum frequency bandwidth B5 and Tdccch time, the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth is used. The broadcast information and packet paging indicator PI information corresponding to all mobile stations are represented by the frequency bandwidth Bn-Bm (n, m> 1; nm = 1) of Bn (n = 1, 2, 3, 4, 5). And using a different error correction system to distribute and map.

Specifically, as shown in FIG. 15A, when the area 1 to which the broadcast information shown in the first embodiment is mapped and the area 2 to which the packet paging indicator PI information is mapped are set as the area 21. The area 21 is divided into two parts, the broadcast information and the packet paging indicator PI information divided into two parts are copied to the areas 24 and 25 within the frequency bandwidth of B4-B3, and the codes are encoded according to the available radio resources. Change the conversion rate.
The broadcast information and the packet paging indicator PI information as described above are not limited to each area within the B4-B3 frequency bandwidth, but within all the Bn frequency bands (that is, Bn-Bm (n, m>1).; All frequency bands of nm = 1), and change the coding rate according to the available resources.

  FIG. 15B shows that the broadcast information and the paging indicator PI information are copied to the frequency bandwidth of Bn (n = 1, 2, 3, 4, 5), and the coding rate is changed by applying different error correction coding. Is shown.

  As described above, the broadcast information and packet paging indicator PI information of all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are used as the frequency of each Bn mobile station class. By mapping to the band, the mobile station of each Bn mobile station class can receive the broadcast information and the packet paging indicator PI information through the minimum frequency bandwidth B1.

  In this embodiment, as the reception quality deteriorates, the frequency bandwidth of the Bn mobile station class or the frequency bandwidth of B1, B2,... Notification information and packet paging indicator PI information in which the conversion rate is adopted can be received. Here, by receiving multiple copy information in different frequency bandwidths, a frequency diversity effect can be obtained and reception quality can be improved. Also, the error correction capability can be improved by increasing the number of redundant bits by changing the error correction method. That is, as shown in the packet transmission / reception flowchart of the mobile station in FIG. 4, all mobile stations of the Bn mobile station class can improve the reception quality through each frequency bandwidth and can operate the standby procedure normally. .

  As described above, the common control information of the broadcast information and the paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth is represented by Bn. It is a feature of the third embodiment that mapping (copying, error correction method change) is performed on each frequency bandwidth (to each frequency bandwidth including Bn and below Bn).

  Reception of the common control information of the mobile station corresponding to the above-described common control information mapping method is performed in the control example as shown in FIG. That is, as a method for mapping the common control information, in a radio resource occupying the maximum frequency bandwidth and Tdccch time, all the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are used. Common control information of broadcast information and packet paging indicator PI information corresponding to the mobile station is mapped (copied, error correction method changed) to the frequency bandwidth of Bn. As a result, in the case of reception quality degradation, all the mobile stations of the Bn mobile station class were copied with the frequency bandwidth of the Bn mobile station class or sequentially expanding the frequency bandwidth of B1, B2,. Broadcast information and paging indicator PI information are received, and reception quality is improved by a frequency diversity effect and an error correction effect.

That is, in FIG. 14, a mobile station of the mobile station class having the maximum frequency bandwidth B5 controls the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the minimum frequency bandwidth B1, and performs a standby procedure (period). Necessary common control information, that is, broadcast information and packet paging indicator PI information can be received. In this case, if the reception quality is deteriorated, the mobile station of the B5 mobile station class sequentially increases the frequency bandwidth of the B5 mobile station class or the frequency bandwidth of B1, B2,..., B5 (T3 in FIG. (Showing reception in the frequency bandwidth of B4), the received broadcast information and packet paging indicator PI information are received, and the reception quality is improved by the frequency diversity effect. Then, in the connection procedure (period) for transitioning to the active mode based on reception of packet paging information or transmission determination, control is performed by expanding the maximum frequency bandwidth B5.

  According to the third embodiment, all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth operate with the minimum frequency bandwidth, and the reception quality deteriorates. In this case, the frequency bandwidth of the Bn mobile station class or sequentially expands the frequency bandwidth of B1, B2,..., Bn to realize low standby power consumption in the standby procedure (period), thereby reducing the size of the mobile station, A long standby time requirement can be realized.

  In FIG. 15B, the redundant bits of the error correction code are decreased as the frequency bandwidth of Bn increases (for example, coding rate 8/9 → 4/5 → 3/4 → 2/3 → 1/2). Thus, the error correction gain decreases as the frequency bandwidth increases, but as shown in FIG. 15C, by increasing the redundant bits of the error correction code as the frequency band of Bn increases, Resource utilization efficiency and frequency diversity effects may be improved.

  In the above embodiment, common control of broadcast information and packet paging indicator PI information corresponding to all mobile stations of the Bn mobile station class including the maximum frequency bandwidth in the radio resource occupying the maximum frequency bandwidth Bn and Tdccch time. Redundant bits of error correction schemes with different information are mapped to Bn frequency bandwidth (error correction scheme change), that is, Bn movement including maximum frequency bandwidth in radio resources occupying maximum frequency bandwidth Bn and Tdccch time Broadcast information and packet paging indicator PI information corresponding to all mobile stations in the station class may not be copied to the frequency bandwidth of Bn, and only redundant bits of different error correction methods for the same information may be added.

When an error occurs in information received from the minimum frequency bandwidth B1 due to quality degradation, redundant bits of different error correction methods of the same information are received from frequency bandwidths other than B1 and decoded again. To do.
FIGS. 15D and 15E show how the coding rate is changed by adding redundant bits of different error correction coding of the same information without copying broadcast information and packet paging indicator PI information to the frequency bandwidth of Bn. Yes.

  Similarly in FIG. 15D, the redundant bits of the error correction code are reduced as the frequency bandwidth of Bn increases (for example, coding rate 8/9 → 4/5 → 3/4 → 2/3 → 1/2). The error correction gain decreases as the frequency bandwidth increases, but by increasing the redundant bits of the error correction code as the frequency band of Bn increases as shown in FIG. The utilization efficiency and frequency diversity effect may be improved.

  As shown in FIG. 18A, the present embodiment expands the portion of the downlink common control channel DCCCH shown in FIG. 5 and maps the common control information included in the downlink common control channel. As a common control information mapping method, all radio stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth in radio resources occupying the maximum frequency bandwidth Bn and Tdccch time are used. The broadcast information and the packet paging indicator PI information corresponding to are copied to the frequency bandwidth of Bn, and are distributed and mapped using different transmission powers.

Specifically, as shown in FIG. 18A, when the area 1 to which the broadcast information shown in the first embodiment is mapped and the area 2 to which the packet paging indicator PI information is mapped are set as the area 21. The area 21 is divided into two parts, and the broadcast information and the packet paging indicator PI information divided into two parts are copied to the areas 24 and 25 within the frequency bandwidth of B4-B3, and transmitted in accordance with the available radio resources. Change the power.
The broadcast information and the packet paging indicator PI information as described above are not limited to each area within the frequency bandwidth of B4-B3, but within all frequency bands of Bn (that is, all frequencies of Bn-Bn-1). Band) and change the transmission power according to the available resources.

FIG. 18A shows a state where the transmission power is changed by copying to the frequency bandwidth of Bn.
As described above, the broadcast information and packet paging indicator PI information of all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are used as the frequency of each Bn mobile station class. By mapping to bands, mobile stations of each Bn mobile station class can receive broadcast information and packet paging indicator PI information through the minimum frequency bandwidth B1.

  In the present embodiment, in accordance with reception quality deterioration, broadcast information using a different transmission power by copying with the frequency bandwidth of the Bn mobile station class or sequentially expanding the frequency bandwidth of B1, B2,..., Bn. And packet paging indicator PI information. By receiving multiple copies of information in different frequency bandwidths, a frequency diversity effect can be obtained and reception quality can be improved. Also, the transmission power can be adjusted and the anti-interference capability can be improved by changing the error correction method, modulation method and code spreading factor. That is, as shown in the packet transmission / reception flowchart of the mobile station in FIG. 4, all mobile stations of the Bn mobile station class improve the reception quality through the Bn frequency bandwidth, and the standby procedure (period) operates normally. can do.

  As described above, the common control information of the broadcast information and the packet paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth, Mapping (copying, changing transmission power, or adding transmission power adjustment to the third to fifth embodiments) to the frequency bandwidth of Bn (to each frequency bandwidth including Bn and below Bn) This is a feature of the sixth embodiment.

  Reception of the common control information of the mobile station corresponding to the above-described common control information mapping method is performed in the control example as shown in FIG. That is, as a method for mapping the common control information, in a radio resource occupying the maximum frequency bandwidth and Tdccch time, all the Bn (n = 1, 2, 3, 4, 5) mobile station classes including the maximum frequency bandwidth are used. The broadcast information corresponding to the mobile station and the common control information of the packet paging indicator PI information are mapped (copied and changed in transmission power to the frequency bandwidth of Bn. Alternatively, the transmission power adjustment is performed in the third to fifth embodiments. Is added). As a result, in the case of reception quality degradation, all the mobile stations of the Bn mobile station class are copied notifications with the frequency bandwidth of the Bn mobile station class or the frequency bandwidths of B1, B2,. Receives information and packet paging indicator PI information, and improves reception quality by improving frequency diversity effect and anti-interference ability.

That is, in FIG. 14, a mobile station of the mobile station class having the maximum frequency bandwidth B5 controls the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the minimum frequency bandwidth B1, and performs a standby procedure (period). Necessary common control information, that is, broadcast information and packet paging indicator PI information can be received. In this case, if the reception quality is deteriorated, the mobile station of the B5 mobile station class sequentially increases the frequency bandwidth of the B5 mobile station class or the frequency bandwidth of B1, B2,..., B5 (T3 in FIG. (Showing reception in the frequency bandwidth of B4), the received broadcast information and packet paging indicator PI information are received, and the reception quality is improved by the frequency diversity effect. Then, in the connection procedure (period) for transitioning to the active mode based on the reception of paging information or the packet transmission judgment, control is performed by expanding the maximum frequency bandwidth B5.
In this way, all mobile stations perform intermittent reception with the minimum frequency bandwidth B1, and the power consumption of the standby procedure (period) in the idle mode can be minimized.

  According to the sixth embodiment, all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth operate with the minimum frequency bandwidth, and the reception quality deteriorates. In this case, the frequency bandwidth of the Bn mobile station class or sequentially expands the frequency bandwidth of B1, B2,..., Bn to realize low standby power consumption in the standby procedure (period), thereby reducing the size of the mobile station, A long standby time requirement can be realized.

  In FIG. 18B, the transmission power is increased (for example, (−8) → (−6) → (−4) → (−2) → (0)) as the frequency bandwidth of Bn increases. Although the interference capability is improved, as shown in FIG. 18C, the radio resource utilization efficiency and the frequency diversity effect may be improved by reducing the transmission power as the frequency band of Bn increases. .

  In the second to sixth embodiments, common broadcast information and packet paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are used. As a method of mapping control information to the frequency bandwidth of Bn, information copying, error correction method change, modulation method change, code spreading factor change, and transmission power change method have been presented, but different frequency bandwidths Bn and Different mapping methods may be employed for radio resources occupying Tdccch time.

As shown in FIG. 15E, only redundant bits of the error correction code can be added. Also, some information related to different frequency bandwidths Bn is copied, various digital signal processing is performed, the generated broadcast information and packet paging indicator PI information are mapped to the specified frequency band, error correction method change, modulation method You may employ | adopt the method of a change, code spreading factor change, and transmission power change.

  In the first to sixth embodiments, broadcast information and packet paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are combined. Are mapped to the minimum frequency bandwidth B1, or are mapped to all frequency bandwidths Bn-Bm (n, m> 1; nm = 1) of Bn, error correction scheme change, modulation scheme change, code spreading Although a method of mapping by mapping by changing the rate and changing the transmission power has been presented, it is applied to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth. The corresponding packet paging indicator PI information may be mapped differently from the broadcast information.

  For example, packet paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth is not mapped to the minimum frequency bandwidth B1. A method (for example, 1.25 MHz) in which radio resources occupying the maximum frequency bandwidth Bn and Tdccch time are divided (for example, divided into groups in units of 1.25 MHz) and packet paging indicators PI of a plurality of mobile stations are grouped (for example, 1.25 MHz) is also conceivable. . In this case, the first to sixth embodiments are applied only to broadcast information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth. Also good. Conversely, when broadcast information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth adopts another mapping method, the maximum frequency bandwidth May be applied only to packet paging indicator PI information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class.

  When the first to sixth embodiments are applied only to broadcast information corresponding to all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth, FIG. The connection procedure (period) shown in FIG. 4 includes checking the packet paging indicator PI information of the incoming call group #n to which the own station belongs (step S4).

Yes.

  Specifically, as shown in FIG. 23, downlink access information is mapped to area 11, area 12 and area 13, and packet paging information is mapped to area 14, area 15 and area 16. Thus, by mapping the downlink access information and packet paging information of all mobile stations of the Bn mobile station class to the frequency bandwidth of Bn (each frequency bandwidth including Bn and below Bn), the Bn mobile station class All mobile stations can receive downlink access information and packet paging information through the frequency bandwidth of Bn.

As described above, the common access information for downlink access information and packet paging information corresponding to all mobile stations of the Bn mobile station class is mapped to the Bn frequency bandwidth (to each frequency bandwidth including Bn and below Bn). This is a feature of the fourth reference example .

The mobile station common control information reception method corresponding to the above-described common control information mapping method is implemented in the control example shown in FIG. That is, since the common control information of the downlink access information and packet paging information corresponding to all the mobile stations of the B5 mobile station class is mapped to the radio resource occupying the frequency bandwidth of the B5 and the Tdccch time, the B5 mobile station class All mobile stations in the above control the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the frequency bandwidth from B1 to B5 when shifting from the standby procedure (period) to the connection procedure (period).

( Fifth reference example )
As described above, EUTRA / EUTRAN technical requirements require spectrum flexibility and support for frequency allocation for different frequency bandwidths (eg, 1.25 MHz, 2.5 MHz, 5 MHz, 10 MHz, 20 MHz). ing.
In this reference example , EUTRA uplink / downlink channel configuration, mobile station packet call transmission / reception flowchart, downlink radio frame configuration, base station and mobile station configuration are the same as in the first embodiment. Therefore, the repeated explanation is omitted.

FIG. 24 is a diagram for explaining a fifth reference example of the present invention. In the fifth reference example , as in the first to fourth reference examples , one of the downlink common control channel mapping methods assumed based on the 3GPP proposal for EUTRA, downlink access information (W− CDMA downlink access channel FACH) and packet paging information corresponding to packet call (corresponding to W-CDMA paging channel PCH) mapping method, and downlink access information and packet paging information mapping method A common control information reception method for mobile stations is proposed.

In the first and second reference examples , the downlink access information and packet paging information of all mobile stations of the Bn (n = 1, 2, 3, 4, 5) mobile station class including the maximum frequency bandwidth are the minimum. Although a method of mapping to the frequency bandwidth B1 has been proposed, since the minimum frequency bandwidth B1 of the system is used, it is easily affected by frequency selective fading. Further, when the reception level fluctuation within the minimum frequency bandwidth B1 is severe, there are cases where downlink access information and packet paging information cannot be received due to reception quality degradation.

Further, as in the fourth reference example , the radio resources occupying the frequency bandwidth of Bn−Bm (n, m>1; nm = 1) (difference between the frequency bandwidths of Bn and Bm) and the Tdccch time. When mapping downlink access information and packet paging information corresponding to all mobile stations of the Bn mobile station class, radio resources may not be sufficiently used in each frequency bandwidth.

  FIG. 24A shows a method of mapping the common control information included in the downlink common control channel by expanding the portion of the downlink common control channel DCCCH shown in FIG. As a method of mapping the common control information, Bn moves to a radio resource occupying a frequency bandwidth of Bn-Bm (n, m> 1; nm = 1) (difference between frequency bandwidths of Bn and Bm) and Tdccch time. Downlink access information and packet paging information corresponding to all mobile stations in the station class are mapped. At this time, for each frequency bandwidth (difference between the frequency bandwidths of Bn and Bm), different error correction methods are adopted and distributed and mapped.

Specifically, as shown in FIG. 24A, the downlink access information is mapped to areas 7 and 8, and the packet paging information is mapped to areas 9 and 10, and different error correction methods are applied at this time. .
Then, as described above, the downlink access information and packet paging information of all the mobile stations of the Bn mobile station class are mapped to the frequency bandwidth of Bn-Bm (n, m>1; nm = 1). By changing the error correction method (for example, coding rate) according to the resources that can be used, all the mobile stations of the Bn mobile station class have Bn-Bm (n, m>1; nm = 1). Downlink access information and packet paging information can be received through the frequency bandwidth. That is, as shown in the packet transmission / reception flowchart of the mobile station in FIG. 4, all the mobile stations of the Bn mobile station class pass through the frequency bandwidth of Bn−Bm (n, m>1; nm = 1). The connection procedure (period) can be operated normally.

  In FIG. 24B, downlink access information and packet paging information are mapped to a frequency bandwidth of Bn-Bm (n, m> 1; nm = 1), and errors are made in accordance with resources available at this time. It shows how the coding rate is changed by applying the correction method.

The mobile station common control information reception method corresponding to the above-described common control information mapping method is implemented in the control example shown in FIG. That is, since the common control information of downlink access information and packet paging information corresponding to all mobile stations of the B5 mobile station class is mapped to the radio resources occupying the frequency bandwidth of B5-B4 and Tdccch time, All mobile stations in the station class control the reception frequency bandwidth, the number of IFFT points, the operation clock, etc. according to the frequency bandwidth from B1 to B5 when shifting from the standby procedure (period) to the connection procedure (period). And common control information necessary for the connection procedure (period), that is, downlink access information and packet paging information can be received.

As a method of mapping the common control information, Bn moves to a radio resource occupying a frequency bandwidth of Bn-Bm (n, m> 1; nm = 1) (difference between frequency bandwidths of Bn and Bm) and Tdccch time. Downlink access information and packet paging information corresponding to all mobile stations in the station class are mapped. At this time, for each frequency bandwidth (difference between the frequency bandwidths of Bn and Bm), a different modulation method (for example, modulation degree) is adopted and distributed and mapped.

By changing the modulation order according to the available resources, all the mobile stations of the Bn mobile station class have a frequency band of Bn-Bm (n, m>1; nm = 1). Downlink access information and packet paging information can be received through the width. That is, as shown in the packet transmission / reception flowchart of the mobile station in FIG. 5, all the mobile stations of the Bn mobile station class pass through the frequency bandwidth of Bn−Bm (n, m>1; nm = 1).

And common control information necessary for the connection procedure (period), that is, downlink access information and packet paging information can be received.
By combining with the first embodiment, all mobile stations of the Bn mobile station class operate with the minimum frequency bandwidth B1 in the standby procedure (period) and operate with the connection procedure (period) from the Bn frequency bandwidth. In the standby procedure (period), the minimum power consumption can be realized, and the mobile station can be downsized and a long standby time can be requested.

  Also in the above case, the modulation rate is decreased (for example, 64QAM → 16QAM → 8QAM → QPSK → BPSK) as the frequency bandwidth of Bn increases, but the modulation rate is decreased as the frequency band of Bn increases. Increasing the wireless resource utilization efficiency and anti-interference capability may be achieved by increasing the number.
