detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The technology described in this article can be used in various third-generation mobile communication systems, such as code division multiple access (CDMA, Code Division Multiple Access) system, wideband code division multiple access (WCDMA, Wideband Code Division Multiple Access), time division synchronous code division multiple access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system, and other such communication systems.

FIG. 1 is a flowchart of a method for transmitting uplink control information provided by Embodiment 1 of the present invention. The execution subject of the following steps is the UE, and specifically, the following operations may be implemented through hardware, software, or a combination of hardware and software. The method of the present embodiment comprises the steps:

Step 100, determine a target code channel from a plurality of preset code channels.

Step 101: Use the target code channel to send uplink information to the network side device, wherein the uplink information includes: first information and second information, and the information bits transmitted by the target code channel carry the first information, so The channelization code of the target code channel carries the second information.

The UE involved in this application is a wireless terminal, which may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via the radio access network (for example, RAN, Radio Access Network), and the wireless terminal can be a mobile terminal, such as a mobile phone (or called a "cellular" phone) and a mobile terminal The computers, which may be, for example, portable, pocket, handheld, built-in or vehicle-mounted mobile devices, exchange speech and/or data with the radio access network. For example, Personal Communication Service (PCS, Personal Communication Service) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL, Wireless Local Loop) stations, Personal Digital Assistant (PDA, Personal Digital Assistant) and other equipment . A wireless terminal can also be called a system, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile station (Mobile), a remote station (Remote Station), an access point (Access Point), Remote Terminal (RemoteTerminal), Access Terminal (Access Terminal), User Terminal (User Terminal), User Agent (UserAgent), User Device (User Device), or User Equipment (User Equipment).

The code channel refers to: among the physical channels used by the UE for uplink transmission, except for a certain number of code channels occupied by sending service data or other control information, the remaining unoccupied code channels. The code channel, that is, the code division channel, is to divide the channel into multiple code channels through a plurality of different spreading codes. The spreading code may be, for example, a variable-order Walsh code (Walsh code), also called an orthogonal variable spreading factor (Orthogonal Variable Spreading Factor, OVSF for short). The variable-order Walsh code is a group of orthogonal spreading codes, and its order, also called spreading factor, can be 2, 4, 6, 8...256. When the spreading factor is k, k is an integer greater than zero, and there are k completely orthogonal spreading codes, then the i-th spreading code in the k completely orthogonal spreading codes, for example, can be expressed as C _ch,k,i . The channelization code of the code channel using the spreading code C _ch,k,i is C _ch,k,i .

The scheme of the above embodiment includes two implementation scenarios: service data of the uplink data channel transmitted through the target code channel, and control information of the control channel transmitted through the target code channel. However, it should be noted that in the two implementation scenarios, the second Information is Control Information.

Use the target code channel to send uplink information to the network side equipment, the information actually transmitted on the target code channel is a part of the uplink information, that is, the first information, and the other part of the uplink information, that is, the second information, that is, control information, Characterized by the channelization code of the target code channel. In this way, the power required for actually sending the uplink information is the power required for sending the first information, while the second information does not require additional sending power. Therefore, the solution of this embodiment reduces the transmission power required for sending uplink information, thereby improving the uplink throughput of the UE.

FIG. 2 is a flowchart of a method for transmitting uplink control information provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention also provides a method for transmitting uplink control information. The execution subject of the method steps in this embodiment is a network side device. Specifically, the following operations may be implemented through hardware, software, or a combination of hardware and software. The method of the present embodiment comprises the steps:

Step 200: Detect the first information sent by the user equipment on multiple preset code channels.

Step 201, if the first information is detected on a code channel of the plurality of code channels, obtain the second information carried by the channelization code of the code channel according to the channelization code of the code channel; The first information and the second information are uplink information sent by the user equipment.

Specifically, the network side device may refer to a device in the access network that communicates with the wireless terminal through one or more sectors on the air interface, for example, it may be a base station. The network-side device can be used to convert received air frames to and from IP packets, and act as a router between the wireless terminal and the rest of the access network, which can include an Internet Protocol (IP) network. The network side device can also coordinate attribute management of the air interface. The network side device may be, for example, a base station. The base station may be a base station (BTS, Base Transceiver Station) in CDMA, or a base station (NodeB) in WCDMA or TD-SCDMA, which is not limited in this application.

The network side device detects the first information on multiple preset code channels, that is, detects the multiple code channels one by one to see whether the information sent by the UE is received.

When information is detected on one of the code channels, which is the first information, stop and continue to detect. The first information is part of the uplink information sent by the user equipment, and the channel of the code channel is obtained according to the channelization code of the code channel The second information represented by the code. So far, the network side device has received all the uplink information sent by the UE.

The method for transmitting uplink control information proposed in Embodiment 2 of the present invention is an implementation method at the receiving end corresponding to the method for transmitting uplink control information provided in Embodiment 1. Its specific beneficial effects are similar to those of Embodiment 1 above. This will not be repeated here.

FIG. 3 is a flowchart of a method for transmitting uplink control information provided by Embodiment 3 of the present invention. This embodiment provides a specific interaction process between the UE and the network side device in an implementation scenario in which the UE sends the control information of the control channel through the target code channel when sending uplink information to the network device.

Further, in the solution of the above embodiment, if the first information is a part of control information sent by any uplink control channel, then the second information is another part of the uplink control information.

As shown in Figure 3, the method of this embodiment includes the following steps:

In step 300, the UE determines the number of control information that can be carried by the channelization code according to the preset number of code channels, and then determines the control information carried by the channelization code.

The control information transmitted through the target code channel is a part of the control information transmitted by the uplink control channel, represented by the first control information, and the uplink control information carried by the channelization code of the target code channel is part of the control information transmitted by the uplink control channel Another part of control information is represented by second control information. In this step, the control information carried by the determined channelization code is the second control information. Therefore, the information carried by the channelization code of the target code channel is the same as the second information, where the channelization codes of the multiple code channels respectively correspond to different information bits.

The preset code channels may be a part of all idle code channels used by the UE for uplink transmission, or all idle code channels. Here, the idle code channels refer to the remaining unoccupied code channels in the physical channels used by the UE for uplink transmission except for a certain number of code channels occupied by sending service data or other control information. Then the number of the preset code channels is less than or equal to the number of idle code channels owned by the UE. Assuming that the number of preset code tracks is N, N is expressed as a power of base 2, that is, 2 ^X , and N is known, then the index X can be obtained by, for example, series expansion through Taylor expansion. The X may be an integer or a decimal. When X is an integer, it is determined that the second control information can be X bit control information; when X is a decimal, then it is determined that the second control information can be the control information of the integer part of X bit, or it can be N types of non-integer bits of control information. The control channel includes a plurality of control information of different functions, and the size of the control information of different functions is different, and the second control information is the control information of a function, which can be all or part of the control information of a function, or can be A combination of control information for multiple functions.

Wherein, the uplink control channel specifically includes at least one of the following:

Dedicated physical control channel DPCCH, enhanced dedicated physical control channel E-DPCCH, high-speed dedicated physical control channel HS-DPCCH; different control channels correspond to different multiple code channels.

Specifically, the dedicated physical control channel (Dedicated Physical Control Channel, referred to as DPCCH), mainly carries the pilot bit (Pilot bit) required for channel estimation by the network side equipment, and the transmission power control (Transmission Power Control, referred to as TPC) information; if the UE needs to send voice and other services, the Transport Format Combination Indicator (TFCI) information of the voice and other services will also be transmitted on the DPCCH; if the UE has correctly received and decoded the voice service sent by the network side device in the current frame , the control information may also include acknowledgment ACK information.

The Enhanced Dedicated Physical Control Channel (E-DPCCH for short) mainly carries the control information sent by the UE to the network side device under the High Speed Uplink Packet Access (HSUPA) service, including Retransmission Sequence Number (Retransmission Sequence Number, RSN for short), Happy Bit, Enhanced Transport Format Combination Indicator (E-TFCI for short) information, etc.

The High Speed Dedicated Physical Control Channel (HS-DPCCH) mainly carries the receiving status information of the Hybrid Automatic Repeat reQuest (HARQ) sent by the UE to the network side equipment, such as the confirmation response Acknowledgment (ACK for short) information, Negative Acknowledgment (NACK for short) information, and Channel Quality Indicator (CQI for short) information.

When the UE transmits at least two types of uplink control information to the network side equipment at the same time, different uplink control channels correspond to different multiple code channels, and the channelization codes of different multiple code channels are different, and the control information of different uplink control channels Therefore, different uplink control channels also correspond to different mapping relationships between channelization codes and control information.

When the uplink control channel is E-DPCCH, the second information includes a retransmission sequence number RSN and/or a happy bit Happy Bit, and the first information includes an enhanced transport format combination indication E-TFCI; or

The second information includes E-TFCI, and the first information includes RSN and/or Happy Bit; or

The second information includes the first part of the E-TFCI, and the first information includes the RSN, Happy Bit and the second part of the E-TFCI; or

The second information includes RSN, and the first information includes Happy Bit.

Specifically, the larger the number of bits of the second information is, the smaller the number of bits of the first information is, and the smaller the transmission power used by the UE to send the first information is. On the basis of ensuring that the number of bits of the second information is as large as possible, the second information may be control information of integer bits or control information of non-integer bits. Fig. 4 is a schematic diagram of the channel format of E-DPCCH in the third embodiment of the present invention. As shown in Fig. 4, one radio subframe of E-DPCCH includes 15 time slots, time slot #0, time slot #1... In slot #14, each transmission timing interval (Transmission Timing Interval, TTI) needs to transmit 10-bit control information, which is encoded into a 30-bit data stream and transmitted on one wireless subframe. The 10-bit control information includes the following 3 parts:

2-bit RSN;

1-bit Happy Bit, when Happy Bit=1, indicates that the UE wishes to obtain more uplink transmission resources;

The 7-bit E-TFCI indicates the size of the transport block sent by the UE in each radio subframe.

For example, if the preset multiple code channels are 2 code channels, the second information is 1-bit Happy Bit, and the first information is RSN and E-TFCI; if the preset multiple code channels are 4 code channels channel, the second information is 2bit RSN, the first information is Happy Bit and E-TFCI; if the preset multiple code channels are 2 ^x code channels, 2<x<7, then the second information is x bit E-TFCI of , the first information includes Happy Bit, RSN and remaining E-TFCI of 7-x bits.

Since the number of E-TFCI bits is relatively large, when the UE determines according to the number of preset code channels that the number of bits of control information that can be carried by the channelization code is greater than the number of bits of RSN and Happy Bit, but less than the number of bits of E-TFCI, For example, if the preset code channels are 32 code channels, it can be determined that the channelization code can represent 5-bit control information, and the content of the second information is all or part of the control information of a function. In order to represent as much control information as possible on the channelization code, to reduce the control information sent on the target code channel, and to reduce the transmission power of the control information, the second information can be determined as a 5-bit E-TFCI. If the preset code channels are 6 code channels, it can be determined that the channelization code can represent 2-bit control information, and the second information is 2-bit RSN.

If in the HSUPA service, at least 128 uplink code channels are required to send a complete number of bits of E-TFCI, when the channelization codes of the code channels in the preset code channels are not enough to carry a complete 7-bit E-TFCI, you can also use the If bits of the E-TFCI are reduced, the second information content may include the reduced E-TFCI information, and the first information includes RSN and/or HappyBit.

If in the HSUPA service, the network side equipment has the ability to blindly detect the format of the data service sent by the user equipment, then the user equipment can stop sending the E-TFCI, then the second information can include RSN, and the first information can include HappyBit. For example, the UE can use 4 code channels to represent four kinds of information of the RSN, and send a 1-bit HappyBit on the code channels.

Further, when the uplink control channel is a DPCCH, the second information is a transport format combination indication TFCI, and the first information includes pilot bits Pilot and/or transmission power control TPC; or

The first information includes Pilot and/or TPC, and the second information is a first acknowledgment ACK or a first non-acknowledgment NACK. The ACK is used to instruct the network side device to terminate the voice service sent in the current frame in advance when the user equipment has correctly decoded the voice service.

Specifically, since the redundancy of the voice service data in each radio frame received by the UE is generally relatively large, the UE may correctly decode the voice service data after receiving a part of the information of the current radio frame, then the subsequent frame of the current frame Part of the voice information does not need to be received again. At this time, the DPCCH control information sent by the UE may also include the first acknowledgment ACK information or the first non-acknowledgment acknowledgment NACK, and the first acknowledgment ACK is sent to inform the network side equipment The UE has correctly decoded the required voice data, and at the same time instructs the network side equipment to terminate the voice service sent in the current frame in advance, which saves time-frequency resources for receiving the voice information of the latter part of the current frame, and reduces the burden on the UE and the network side. equipment burden.

It should be noted that the first acknowledgment ACK here is different from the ACK in the automatic repeat response. The first acknowledgment ACK indicates that the receiving end terminates the subsequent voice service of the current frame in advance, while the automatic repeat response Medium ACK is used to instruct the receiver to continue sending subsequent data. The method for determining the second information of the DPCCH is similar to the method for determining the second information of the E-DPCCH described above, and will not be repeated here.

When the uplink control channel is HS-DPCCH, the second information is a channel quality indicator CQI, the first information includes a hybrid automatic repeat request HARQ indication or a fixed bit sequence; the HARQ indication includes a second confirmation response ACK or second non-acknowledgment NACK; or,

The second information includes a hybrid automatic repeat request HARQ indication, and the first information includes a CQI; or,

The first information includes a CQI, and the second information includes an identifier of the CQI; the identifier of the CQI is used to indicate to the network side device whether the CQI is obtained by calculation before interference elimination or after interference elimination.

Specifically, if the network side device did not send downlink data at the previous moment, the UE does not need to send a HARQ indication. If the CQI is to be transmitted at this time, the first control information has no message to transmit, so the UE needs to send a fixed bit sequence. as the first information.

Further, if the UE has a certain ability to eliminate the downlink interference of adjacent cells, then the UE may include a CQI identifier in the second information, and the CQI identifier indicates that the currently reported CQI value is before the channel interference caused by the adjacent cells is eliminated. It is obtained by calculation, or is obtained by calculation after the interference is eliminated, so that the network side equipment can more accurately schedule downlink data for the UE.

The method for determining the second information of the HS-DPCCH is similar to the above method for determining the second information of the E-DPCCH, and will not be repeated here.

According to the content of the control information carried by the channelization code, that is, the content of the second control information, the target code channel is determined among multiple code channels, which may be through a preset mapping relationship table or database between channelization codes and control information Matching and searching the content of the second control information, the channelization code corresponding to the second control information, that is, the channelization code of the target code channel, so that a target code channel can be determined from multiple code channels to transmit the first code channel of the control channel - control information.

Taking the spreading factor of 256 as the code channel unit, assuming 4 code channels are preset, the 4 code channels can be C _ch,256,1 , C _ch,256,2 , C ch,256,3 , C _ch,256,3 , C _ch,256,4 , then it can be determined that the control information that can be represented by the channelization code is 2-bit control information. When the control information that the UE needs to transmit is E-DPCCH control information, the second control information is 2-bit RSN, then the first information is 8-bit control information, that is, 1-bit Happy Bit and 7-bit E-TFCI.

In step 301, the UE determines a target code channel from multiple code channels to carry the first information to be sent according to the control information carried by the channelization code determined in step 301 .

The information carried by the channelization code of the target code channel and the information of the second information, wherein the channelization codes of the multiple code channels respectively correspond to different information.

Since the control information of the transmitted uplink control channel may change in each TTI, the control information carried by the channelization code in each TTI may also change. Therefore, in a certain TTI, the control information of the uplink control channel that needs to be transmitted When the information changes, the target code track needs to be selected according to the specific content of the second information.

It should be noted that, in an implementation scenario where the UE sends the control information of the control channel to the network side device on the target code channel, the UE may determine one code channel among the preset multiple code channels as the target code channel.

Further, before step 300, it also includes:

Step 300a: The user equipment receives the second configuration signaling sent by the network side device, the second configuration signaling is used to indicate the multiple code channels corresponding to the uplink control channel, and the multiple code channels The other part of the control information used to carry the uplink control channel.

Alternatively, before step 300, the method also includes:

Step 300b: The user equipment determines the multiple code channels corresponding to the uplink control channel and the channelization codes for the multiple code channels according to at least one of the current code channel usage status and the currently scheduled service status. The other part of control information carried on the uplink control channel.

Specifically, before determining the target code channel from the multiple code channels, the UE also needs to know the multiple code channels corresponding to the transmitted uplink control channel and the control information carried by the channelization codes of the code channels. The control information that can be carried by the multiple code channels and the channelization codes of the code channels can be one or more code channels corresponding to the current need to send the uplink control channel configured through the second configuration signaling sent by the network side device, and the code channel The channelization code is used to carry the control information. The second configuration signaling includes radio resource control (Radio Resource Control, RRC for short) signaling.

The network side device may determine the code channel and another part of the control information of the uplink control channel used to bear according to at least one of the current code channel usage status and the service status that needs to be scheduled. Specifically, multiple code channels corresponding to multiple different uplink control channels and the channelization codes of the code channels are pre-configured on the UE side to carry the control information, and the UE uses the current code channel usage status and the current scheduled service status. At least one of them, from which a plurality of code channels corresponding to the uplink control channel and another part of control information of the uplink control channel used for transmission are selected.

The usage status of the current code channel, that is, the status of the code channel of the physical channel currently used for uplink transmission and/or the size of the data of the uplink service transmitted on the corresponding code channel. According to the currently scheduled service status, the UE can determine the control information of the uplink control channel that needs to be sent, and then determine the multiple code channels corresponding to the uplink control channel and the control information carried by the channelization codes of the code channels.

When the UE is in different working states, such as the type or quantity of service data sent or received, data sent or received in different ways, etc., the usage status of its code channel is different.

The spreading factors used by different physical channels may be different, and the size of the spreading factor depends on the size, transmission rate and information accuracy requirements of the service data or control information transmitted on the physical channel. When the content of the transmitted information is relatively small and the accuracy of the information is not high, a small spreading factor is usually selected; when the information to be transmitted requires high accuracy but low transmission rate requirements, a larger spreading factor is usually selected. the spreading factor. For example, when transmitting a signal through DPDCH, the spreading factor is 4-256; when transmitting a signal through HS-DPDCH, the spreading factor is 128-256; when transmitting a signal through E-DPDCH, the spreading factor is 2-256. In the embodiment of the present invention, a spreading factor of 256 is used as a code channel unit, that is, it is assumed that the UE has 256 code channels.

For example, when the UE only transmits voice and/or data and its corresponding control information, other situations are not considered. DPDCH is the basic service bearer channel of the physical layer in the UMTS system. The UE uses 6 code channels to send DPDCH data. The in-phase and quadrature signals respectively occupy 3 code channels, using C _ch,4,1 and C _ch, respectively. _4,2 , C _ch,4,3 , C _ch,4,1 , C _ch,4,2 , C _ch,4,3 represent 64 code channels with a spreading factor of 256; UE will use one code channel Send the control information of the HS-DPCCH, the code channel C _ch,256,1 ; and the UE will send the control information of the DPCCH through the code channel C _ch,256,0 under any circumstances. All the physical code channels of the UE are 256, so in this case, at least 62 code channels of the UE are not used.

When the UE is in other situations, the calculation method of at least the number of unused code channels is similar to the above calculation method and explanation, and will not be repeated here.

The method of determining the code channel, for example, when the UE transmits uplink voice service data through high-speed uplink packet access, for the voice of the Adaptive Multi-Rate (Adaptive Multi-Rate) voice coding algorithm, referred to as AMR voice, due to its The data is generally relatively small, the spreading factor used is 128, and the code channel used is C _ch,128,32 . For video telephony data, the transmission rate is generally high, that is, the continuity of video passing is required, and the spreading factor is even smaller, which is 32, and the code channel used is C _ch,32,8 . Here, the spreading factor is 256 as the code channel unit, that is, the physical code channels used for uplink transmission are 256 code channels. The channelization codes are C ch,128,32, the channelization codes represented by spreading factor 256 are C ch, _256,64 , the channelization codes are C _{ch ,32,8} code channels, and the spreading factor is 256 The channelization code represented by a frequency factor of 256 is C _ch,256,64 . The code channel used to transmit the control information of the DPCCH is C _ch,256,0 , then it can be pre-agreed that the UE uses any K code channels from C _ch,256,1 to C _ch,256,63 as the corresponding E-DPCCH multiple code channels.

When the UE sends uplink service data through multiple-input multiple-output (MIMO), the code channel used to transmit the control information of DPCCH is C _ch,256,0 , and the code channel used to transmit the control information of S-DPCCH is C _{ch ,256,31} , the code channel used to transmit the control information of HS-DPCCH is C _ch,128,16 , the code channel used to transmit the control information of SE-DPCCH is C _ch,4,1 , C _{ch,128, 16} can be expressed as C _ch,256,32 , C _ch,4,1 can be expressed as C _ch,256,64 , then it can be pre-agreed that the UE uses C _ch,256,1 ~ C _ch,256,30 and C _ch, Any K code channels from _256,33 to C _ch,256,63 are used as multiple code channels corresponding to the E-DPCCH.

In other cases, the method for determining the multiple code channels corresponding to the uplink control channel is similar to the above-mentioned determination method and explanation, and will not be repeated here.

The method in which the channelization code of the code channel is used for the carried control information may be determined according to the mapping relationship between the channelization code of the code channel and the control information sent by the network side device or established by itself. In the mapping relationship between the channelization code and the control information of the code channel, the channelization code corresponds to the second information one by one. For example: 2bit RSN is 00, the corresponding channelization code can be C _ch,256,1 for example; 2bit RSN is 01, the corresponding channelization code can be C _ch,256,2 for example; 2bit RSN is 10, The corresponding channelization code may be, for example, C _ch,256,3 ; the 2-bit RSN is 11, and the corresponding channelization code may be, for example, C _ch,256,4 .

When the 2-bit RSN is 10, the target code channel can be determined to be the code channel corresponding to the channelization code C _{ch,256,3 according} to the mapping relationship between the channelization code and the control information of the code channel.

In step 302, the UE sends first information to the network side device on the target code channel determined in step 301.

That is, it is sent to the network side device on the code channel corresponding to the channelization code C _ch,256,3 .

Step 303 , the network side device detects on multiple preset code channels one by one, so as to obtain a part of the information of the uplink control channel, that is, the first information.

The network-side device detects one by one on multiple preset code channels. When there are four code channels, the four code channels may be detected one by one according to the size of the channelization code.

Step 304: When the network side device detects the first information on one of the code channels, obtain the second information according to the channelization code of the code channel, so as to obtain the complete control information of the uplink control channel.

The network-side device detects and decodes the first information on one of the preset multiple code channels, that is, the 8-bit E-DPCCH, and at the same time can obtain the channelization code of the code channel as C _ch,256,3 , Therefore, another 2-bit RSN of the E-DPCCH can be obtained according to the mapping relationship between the channelization code of the code channel and the corresponding control information, thereby obtaining a complete 10-bit E-DPCCH.

In the embodiment of the present invention, by determining the first information and second information of different uplink control channels, the UE determines a target code channel among the preset multiple code channels to send the first information, and uses the target code channel The channelization code carries the second information, reduces the transmission power used by the UE to send the control information of the uplink control channel, increases the control information for sending the uplink service data, and improves the uplink throughput of the UE, and the transmission method of the uplink control information is applicable to The method has wide applicability for transmitting control information of different types of uplink control channels.

FIG. 5 is a flowchart of a method for transmitting uplink control information provided by Embodiment 4 of the present invention. This embodiment provides a specific interaction process between the UE and the network side device in an implementation scenario where the UE sends control information corresponding to the uplink data channel to the network side device on the target code channel. The method of the present embodiment comprises the steps:

Step 500, the UE determines at least one code channel from the multiple code channels as the target code channel to carry the to-be-sent code channel according to the control information corresponding to the uplink data channel and the control information carried by the channelization code of the preset code channel. Service data sent by the uplink data channel.

Specifically, when the data volume of the service data of the uplink data channel transmitted by the UE is not very large, the multiple code channels configured for transmitting the service data of the uplink data channel will be in an idle state, and the services of the uplink data channel are transmitted There may be more than one code channel for data, and the channelization codes of these code channels can carry the control information corresponding to the uplink data channel, so as to reduce the power of directly sending the control information corresponding to the uplink data channel. The UE may determine at least one code channel among the preset multiple code channels as a target code channel to transmit service data corresponding to the uplink data channel, and use the channelization codes of these code channels to carry control information corresponding to the uplink data channel.

Further, the uplink data channel is an enhanced dedicated physical data channel E-DPDCH, and the control information corresponding to the uplink data channel is E-TFCI; or,

The uplink data channel is E-DPDCH, and the control information corresponding to the uplink data channel is a retransmission sequence number RSN and/or a Happy Bit.

Specifically, when the UE transmits service data HSUPA service data, the HSUPA service data is usually sent through an Enhanced Dedicated Physical Date Channel (Enhanced Dedicated Physical Date Channel, E-DPDCH for short). In the prior art, when transmitting E-DPDCH data, the UE must simultaneously transmit E-DPCCH control information, such as E-TFCI. In this solution, when the amount of E-DPDCH data transmitted is not large, the control information of the E-DPDCH part can be carried by the channelization code of the code channel for sending E-DPDCH data when sending E-DPDCH data, for example, when When the size or format of the transmitted data block is complex, the E-TFCI can be carried by the channelization code to indicate the size of the data block in the E-DPDCH, and there is no need to transmit the E-TFCI through the code channel transmission information, thus saving transmission time. The transmission power used by E-TFCI; or, when the transmitted data block is a retransmission data block, the RSN can be carried by the channelization code so that the network side device can determine the retransmission data block according to the RSN; or, send E-DPDCH The data is that after the network-side device allocates resources to the UE, it can only carry the Happy Bit through the channelization code to inform the network-side device whether it is satisfied with the allocated resources, and does not need to transmit information through the code channel to send RSN and/or Happy Bit , thus saving the sending power used for sending the RSN and/or Happy Bit.

Since the format of sending E-DPDCH data, retransmitted data feedback and/or resource allocation may change in each TT1, in different TTIs, the corresponding E-DPCCH control information E-TFCI, RSN and/or HappyBit may also change.

Further, before the above-mentioned step 500 determines the target code channel, it also includes:

Step 500a: The UE receives the first configuration signaling sent by the network side device, the first configuration signaling is used to indicate the multiple code channels corresponding to the uplink data channel, and the channelization of the multiple code channels The code is used to carry the control information corresponding to the uplink data channel.

Alternatively, before determining the target code channel in the above step 500, the method further includes:

Step 500b: The UE determines the multiple code channels corresponding to the uplink data channel according to at least one of the usage state of the current code channel and the currently scheduled service state, and the channelization codes of the multiple code channels are used for Control information corresponding to the uplink data channel carried.

The first configuration signaling includes RRC signaling. The process of determining multiple code channels corresponding to the uplink data channel and the channelization codes of the multiple code channels used to carry the control information corresponding to the uplink data channel is the same as determining multiple codes corresponding to different uplink control channels in the third embodiment The process of using the channelization codes of the channel and multiple code channels to carry the control information is similar and will not be repeated here.

In step 501, the UE sends the service data of the uplink data channel to the network side device on the target code channel determined in step 500.

In step 502, the network side device detects on multiple preset code channels one by one, so as to obtain the service data of the uplink data channel.

Step 503: When the network side device detects the service data of the uplink data channel on at least one of the preset code channels, according to the channelization code of the at least one code channel, obtain the channelization code for the at least one channel Control information corresponding to the uplink data channel carried.

In the embodiment of the present invention, when transmitting the service data of the uplink data channel, at least one target code channel is determined and the service data of the uplink data channel is sent, and the channelization code of the at least one target code channel is used to bear the corresponding The control information of the uplink data channel does not need to be sent through a dedicated control channel, reducing the transmission power used to send the control information, and improving the uplink throughput of the UE.
