The embodiment of the invention provides a resource allocation method, which is applied to a mobile communication system (especially a cellular communication system independently working in an unlicensed frequency band, such as MulteFire) in the unlicensed frequency band, and the transmission process of a common control channel between a terminal and a base station in the unlicensed frequency band.
The mobile communication system may be a WCDMA (Wideband Code Division Multiple Access), CDMA2000(Code Division Multiple Access 2000), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), WiMAX (world Interoperability for Microwave Access), LTE/LTE-a (Long Term Evolution/Long Term Evolution-Advanced), LAA (localized-Assisted Access, radio Access based on authorized frequency bands), multimedia fire, and a fifth, sixth, and nth generation mobile communication systems that may appear subsequently.
The base station refers to a form of a radio station, and refers to a radio access network device that transmits a control channel to a terminal through a mobile switching center in a certain radio coverage area, so that the terminal determines invocation information of a data channel according to the control channel.
The terminal refers to a terminal side product capable of supporting a communication protocol of a land mobile communication system, and a special communication Modem module (Wireless Modem) can be integrated by various terminal forms such as a mobile phone, a tablet computer, a data card and the like so as to complete a communication function. The terminals provided in the embodiment of the invention are all terminals in an unauthorized frequency band, and are simply referred to as terminals for convenience of description.
As shown in fig. 1, the method includes:
101. the terminal acquires resource allocation information of a common control channel.
The common control channel refers to a control channel that can be commonly used by a CE (coverage enhancement) user, and is used for a terminal to acquire a control signaling to determine scheduling information of a data channel. The data channel is used to carry common broadcast data information or user-specific data information. That is, the common control channel implements coverage enhancement, supporting CSS (common search space) and USS (UE-specific search space).
The public broadcast data includes a paging Message (paging Message), System Information (SI), or downlink transmission in a Random access procedure (e.g., RAR and Msg 4, Random access response, and Message 4).
It should be noted that the control signaling acquired through the common control channel includes, but is not limited to, scheduling information used for determining a corresponding data channel, such as transmission power of the data channel or other information.
The resource allocation information comprises the number of sets of the common control channels and/or the total frequency domain resource size of the common control channels and/or the frequency domain resource size of each set of the common control channels, the position of the common control channels on the frequency domain, the starting position of the common control channels in one transmission time interval and the position of the common control channels on the time domain.
Wherein the resource allocation information is used to indicate transmission of a common control channel. The resource allocation information may be obtained by the terminal through the base station, or may be obtained by the terminal through a predefined condition.
102. And the terminal acquires a common control channel sent by the base station according to the resource allocation information.
103. And the terminal determines the scheduling information of the data channel according to the acquired common control channel.
And after acquiring the common control channel sent by the base station according to the resource allocation information, the terminal performs merging decoding on the acquired common control channel to acquire scheduling information of a corresponding data channel.
It should be noted that, in order to perform coverage enhancement on the control channel of the CE user, the embodiment of the present invention sends a control signaling for data channel scheduling to the CE user through the common control channel. The common control channel is a common control channel introduced based on the original control channel of the CE user. The original control channel of the user may be a Physical Downlink Control Channel (PDCCH) or an enhanced physical downlink control channel (ePDCCH). The embodiment of the invention is explained based on the ePDCCH, and the ePDCCH is subjected to coverage enhancement and is used for a CE user to obtain a control signaling. For differentiation, the coverage enhanced ePDCCH is named fecpdcch (further ePDCCH), on which a common control channel is introduced and named common fecpdcch.
The embodiment of the invention provides a resource allocation method, aiming at a communication system working in an unauthorized frequency band, a public control channel is introduced to determine the scheduling information of a data channel through resource allocation, and the public control channel can be repeatedly transmitted on time frequency through the interaction of a base station and a terminal, so that the coverage enhancement of the control channel in the unauthorized frequency band communication system is realized.
Further, with reference to the foregoing method flow, when the resource allocation information includes any two information of three information, that is, the number of sets of common control channels, the total frequency domain resource size of the common control channels, and the frequency domain resource size of each set of common control channels, the terminal calculates another unknown information in the three information according to two known information in the three information.
The terminal determines the frequency domain resources (transmission resources occupied in the whole system bandwidth) of the common control channels according to the number of the sets of the common control channels, any two information of the total frequency domain resource size of the common control channels and the frequency domain resource size of each set of the common control channels, and the positions of the common control channels on the frequency domain. And, the terminal further determines the time domain resource of the common control channel (the transmission resource occupied in the time domain) according to the starting position of the common control channel in one transmission time interval and the position of the common control channel in the time domain.
Further, in combination with the foregoing method flow, the terminal may obtain the resource allocation information through broadcast information sent by the base station, or may obtain the resource allocation information according to a predefined condition, so as to implement step 101, another possible implementation manner of the embodiment of the present invention further provides the following method flow, which specifically includes the following two implementation methods.
The first implementation, as shown in fig. 2, includes:
1011. and the terminal acquires the broadcast information sent by the base station and determines the resource allocation information of the common control channel through the broadcast information.
Wherein the broadcast information is used for carrying resource allocation information indicating common control channel transmission.
The type of the broadcast Information includes Master Information (MIB) and/or System Information (SIB1, System Information Block 1). The MIB is carried by a Physical Broadcast Channel (PBCH) of the unlicensed frequency band communication system. Both the MIB and SIB1 are system information that CE users can receive.
The second implementation, as shown in fig. 3, includes:
1012. the terminal acquires a predefined condition and determines the resource allocation information of the common control channel according to the predefined condition.
The predefined condition may be a fixed condition or a preset rule.
In order to more clearly explain the detailed process of acquiring resource allocation information by the terminal and other method flows that may be involved in the process of acquiring resource allocation information, the following description will be made for the process of acquiring the number of sets of common control channels, the total frequency domain resource size of the common control channels, the frequency domain resource size of each set of common control channels, the position of the common control channels in the frequency domain, the starting position of the common control channels in one transmission time interval, and the position of the common control channels in the time domain by the terminal, respectively.
First, regarding the number of sets of common control channels:
as described in steps 1011 and 1012, the terminal may obtain the number of sets of the common control channels through the broadcast information sent by the base station; the number of sets of common control channels may also be obtained through predefined conditions, for example, the number of sets of system fixed common control channels is 1.
Further, with reference to the foregoing method flow, the number of sets of the common control channels may be 1, or may be any natural number greater than 1 (for example, the number of sets of the common control channels is 2). When the number of sets of common control channels is greater than 1, another possible implementation manner of the embodiment of the present invention provides the following two implementation manners for how to decode the set of common control channels, that is, the process of determining the scheduling information of the data channel according to the acquired common control channel in step 103 includes the following two different method steps.
A first implementation, comprising:
1031. the respective sets of common control channels are jointly decoded.
Step 1031 refers to that the terminal acquires the time-frequency resources of each common control channel set, arranges the time-frequency resources into a logic resource in a certain manner, and jointly decodes all the time-frequency resources on the logic resource.
As shown in fig. 4, for a schematic diagram of jointly decoding each common control channel set, in fig. 4, 201 and 202 denote frequency domain resources of a first common fecpdcch set, and 203 and 204 denote frequency domain resources of a second common fecpdcch set. After receiving all the time-frequency resources of the public FePDCCH, the users combine the time-frequency resources into the logic resources of the public FePDCCH, arrange the logic resources from small to large by the indexes (eCCE #1, 2 … N-1 and N) of eCCE (enhanced control channel element), and then decode control signaling #1, 2 … K-1 and K. Wherein N and K are natural numbers.
A second implementation, comprising:
1032. each set of common control channels is decoded independently.
Step 1032 refers to that the terminal acquires the time-frequency resources of each common control channel set, acquires the logic resources of each common control channel set in a certain manner, and independently decodes the common control channel in each set on the logic resources corresponding to each set.
As shown in fig. 5, for a schematic diagram of independently decoding each common control channel set, in fig. 5, 301 and 302 represent frequency domain resources of a first common fecpdcch set, and 303 and 304 represent frequency domain resources of a second common fecpdcch set. After receiving the time-frequency resources of two public fecpdcch, the user constructs the logical resources 311 of the first public fecpdcch set and the logical resources 322 of the second public fecpdcch set respectively, that is, the logical resources are arranged from small to large according to the indexes of ecces (eCCE #1, 2 … N-1, N, eCCE #1, 2 … M-1, M), and then independently decodes the control signaling (control signaling #1, 2 … K-1, K, control signaling #1, 2 … L-1, L) in each set. Wherein N, M, K and L are natural numbers.
Second, regarding the total frequency domain resource size of the common control channel:
as described in steps 1011 and 1012, the terminal may obtain the total frequency domain resource size of the common control channel through the broadcast information sent by the base station; the total frequency domain resource size of the common control channel may also be obtained through a predefined condition, for example, the total frequency domain resource size of the system default common control channel is 4 PRB (physical resource block) pairs, or 8 PRB pairs or 16 PRB pairs.
When the terminal obtains the total frequency domain resource size of the common control channel through the broadcast information sent by the base station, the total frequency domain resource size of the common control channel may be determined in an indexing manner: for example, the broadcast information informs an index of a resource size of the common control channel. When the index is 0, corresponding to 4 PRB pairs; when the index is 1, 8 PRB pairs are corresponded; when the index is 2, 16 PRB pairs are corresponded.
Third, with respect to the frequency domain resource size of each set of common control channels:
as shown in steps 1011 and 1012, the terminal may obtain the frequency domain resource size of each common control channel set through the broadcast information sent by the base station; the frequency domain resource size of each common control channel set may also be obtained through predefined conditions, for example, the frequency domain resource size of each common control channel set is set to be 8 PRB pairs by default.
Here, how the terminal calculates another unknown information when passing through any two information of the three information, i.e., the number of sets of common control channels, the total frequency domain resource size of the common control channels, and the frequency domain resource size of each set of common control channels, is described as an example.
In example 1, when the number of sets of common control channels is 2 and the total frequency resource size of the common control channels is 16 PRB pairs, it can be seen that the frequency resource size of each set of common control channels is 16/2 — 8 PRB pairs.
Example 2, the frequency domain resource size of each common control channel set is given, that is, the frequency domain resource sizes of a plurality of common control channel sets are listed. For example, given 4 and 8, that is, indicating that the frequency domain resource size of the 1 st common control channel set is 4 PRB pairs and the frequency domain resource size of the 2 nd common control channel set is 8 PRB pairs, respectively, it can be known that the total frequency domain resource size of the common control channels is 4+8 — 12 PRB pairs.
Fourth, regarding the location of the common control channel on the frequency domain:
as shown in step 1011, the terminal may obtain the location of the common control channel on the frequency domain through the broadcast information sent by the base station. It should be noted that, when there are multiple common fecpdcch sets, the position of each common fecpdcch set in the frequency domain has corresponding independent resource allocation information or total joint resource allocation information.
As shown in step 1012, the terminal may also obtain the location of the common control channel in the frequency domain through a predefined condition, that is, the terminal may determine the location of the common control channel in the frequency domain through a preset rule.
Different preset rules can be provided for the terminal to acquire the position of the common control channel on the frequency domain through the preset rules, but all the preset rules include functions of part or all parameters of cell id (cell identification) and downlink system bandwidth (subframe index). For example, the following three different preset rules are named as a first preset rule, a second preset rule, and a third preset rule for distinguishing.
First, expressions of three preset rules are given based on 1 common fecpdcch set.
(1) The first preset rule has the following expression:
wherein R isiRepresents the ith PRB pair in the common FePDCCH resource;representing a cell ID;representing a downlink system bandwidth; m represents the resource size of the common fecpdcch, i.e. the number of PRB pairs.
(2) The second predetermined rule is expressed as follows:
wherein the parameter meaning is the same as the first preset rule.
(3) In order to achieve that the common fecpdcch has different Transmission resources in different TTIs (Transmission Time intervals). Wherein, 1 TTI refers to a time interval occupied by one transmission of a data channel in the time domain. The frequency domain resource of the public fecpdcch may be frequency hopped in the time domain, and there is a third preset rule as follows:
wherein n issfRepresents a TTI index; f. ofhopIndicates the frequency hopping interval in the time domain, and also indicates the number of PRB pairs. The other parameters are as defined in the first predetermined rule.
Wherein, the fhopConfiguration may be performed through broadcast information transmitted by the base station, such as MIB or SIB 1; f ishopOr may be determined by predefined conditions.
Wherein, said nsfMay be a subframe index within one specific transmission period of the common fecpdcch. Including a sub-in a radio frameFrame index (the value range can be 0-9); or the subframe index (the value range can be 0-1023) in one system frame period.
Secondly, when a plurality of public FePDCCH sets exist, the number of the sets is Ncommon fePDCCHThe location of the common fecpdcch in the frequency domain may still be determined based on the above three preset rules. For convenience of description, use SjDenotes the frequency domain resource occupied by the jth common fecPDCCH set, S0Indicating the frequency domain resources occupied by the 1 st common fecpdcch set.
S0Can be obtained by the method of the first preset rule, the second preset rule or the third preset rule, S0I.e. is Ri(i-0, 1, …, M-1). SjCan be based on S0Calculating to obtain the frequency domain resource occupied by the 1 st public fecpdcch set, namely adding a frequency domain offset to the frequency domain resource occupied by the 1 st public fecpdcch set to obtain the frequency domain resources occupied by other public fecpdcch sets, wherein the frequency domain resource occupied by the other public fecpdcch sets specifically has the following expression:
wherein f isshiftRepresenting a fundamental frequency domain offset;indicating the downlink system bandwidth.
Wherein, the fshiftConfiguration may be performed through broadcast information transmitted by the base station, such as MIB or SIB 1; f isshiftOr may be determined by predefined conditions.
Fifth, regarding a start position of the common control channel within one transmission time interval:
as described in steps 1011 and 1012, the terminal may obtain a starting position of the common control channel within one transmission time interval through broadcast information transmitted by the base station; the starting position of the common control channel within one transmission time interval may also be obtained by predefined conditions.
Wherein, the starting position of the common FePDCCH in one TTI is represented asI.e. the starting OFDM (Orthogonal frequency division multiplexing) symbol index of the common fecpdcch within one TTI. When in useA value of 0 indicates that the common fecpdcch is transmitted from the first OFDM symbol of one TTI.
Wherein,greater than the cut-off symbol (cut-off OFDM symbol) index m of the PDCCH, i.e., at least satisfiesHere, the end symbol index of the PDCCH in one system is obtained by a CFI (control format indicator), that is, m is CFI-1. Thus, there areThe CFI is transmitted through a PCFICH (physical control format indicator channel).
As shown in fig. 5A, a schematic diagram of a relationship between OFDM symbols occupied by a PDCCH and a common ePDCCH. c denotes a PDCCH, and a denotes an off symbol index of the PDCCH. As shown in fig. 5A, the PDCCH occupies the first 3 OFDM symbols of the first slot in the TTI, with the cutoff symbol being OFDM symbol # 2. d denotes a common fecpdcch, and b denotes a start symbol (start OFDM symbol) index of the common fecpdcch. As shown in fig. 5A, b is OFDM symbol #3 of the first slot in the TTI.
Typically, the CE user does not need to know the CFI value. Considering CE user meetingThe CE user needs to know the CFI value in order to detect both PDCCH and common fecpdcch to obtain control signaling. CE users do not decode PCFICH, but rather by decodingAnd obtaining the value of the CFI. For example, according to a defined relationAnd decoding the value of the CFI.
Wherein,can always be fixed, i.e. the value ofThe value of (a) is predefined and does not need signaling for setting.The value of (c) may also be variable. And, in the case of different data transmission,the values of (a) are different. For example, when broadcast data (e.g., SI, Paging, etc.) of the system is to be transmitted in one TTI,is always fixed to 2, i.e. starting from the 3 rd OFDM symbol. When the proposed broadcast data is not contained in one TTI,is obtained according to the signaling configuration information of the system. Therein is configured ofIs carried within the MIB or SIB 1.
Sixth, regarding the position of the common control channel in the time domain:
as described in steps 1011 and 1012, the terminal may acquire the location of the common control channel in the time domain through the broadcast information sent by the base station; the location of the common control channel in the time domain may also be obtained by predefined conditions.
In order to achieve coverage enhancement, the common fecpdcch needs to be transmitted repeatedly in the time domain, and each transmission of the common fecpdcch needs multiple TTIs.
The starting position of one common FePDCCH in the time domain can be any TTI, namely, one common FePDCCH can be transmitted in each TTI; it is also possible to specify TTIs, i.e. the starting position in the time domain of one common fecpdcch is limited to certain TTIs.
Wherein the designated TTI can be a TTI with an index being a multiple of the duration of the common FePDCCH.
Wherein the duration of the common fecpdcch refers to the number of TTIs required for complete transmission of one common fecpdcch in the time domain.
As shown in fig. 6, a schematic diagram of the starting position of the common fecpdcch in the time domain is any TTI. As shown in fig. 6, transmission of one common fecpdcch requires N TTIs. 430 and 440 represent two common fecpdcch transmitted independently in the time domain, starting at TTI401 and TTI402, respectively, i.e. one common fecpdcch may start at any one TTI.
As shown in fig. 7, the starting position of the common fecpdcch in the time domain is represented by a TTI with an index equal to a multiple of the duration of the common fecpdcch. As shown in fig. 7, transmission of one common fecpdcch requires N TTIs. 530 and 540 represent two common fecpdcch transmitted independently in the time domain, respectively, starting at TTI501 and TTI511, respectively, where 501 and 511 are each multiples of N.
Further, in combination with the foregoing method flow, in order to further perform coverage enhancement on the control channel received by the terminal, the base station sends a high-level signaling to instruct the terminal to jointly detect the control channel to determine the scheduling information of the data channel, so that another possible implementation manner of the embodiment of the present invention further provides the following method flow, before step 103, as shown in fig. 8, including:

Then the step 103 comprises the step of,
1033. and the terminal determines the scheduling information of the data channel according to the acquired common control channel and the acquired control channel.
