detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The techniques described herein can be used in a variety of third generation mobile communication systems, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Synchronization Codes. 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 according to Embodiment 1 of the present invention. The execution of the following steps is a UE, and the following operations may be implemented by hardware, software, or a combination of hardware and software. The method of this embodiment includes the following steps:

Step 100: Determine a target code channel from a preset plurality of code channels.

Step 101: The uplink information is sent to the network side device by using the target code channel, where the uplink information includes: first information and second information, where information bits transmitted by the target code channel carry the first information, where The channelization code of the target code channel carries the second information.

The UE involved in the present application is a wireless terminal, which may be a device that provides voice and/or data connectivity to the user, a handheld device with wireless connectivity, or other processing device connected to the wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network), which can be a mobile terminal, such as a mobile phone (or "cellular" phone) and with a mobile terminal The computers, for example, can be portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile devices that exchange language and/or data with the wireless access network. For example, personal communication service (PCS, Personal Communication Service) telephone, cordless telephone, Session Initiation Protocol (SIP) telephone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA, Personal Digital Assistant), etc. . A wireless terminal may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, or an access point. Remote Terminal, Access Terminal, User Terminal, User Agent, User Device, or User Equipment.

The code channel refers to: the unoccupied code channel remaining in the physical channel used by the UE for uplink transmission except that the service data or other control information is used to occupy a certain number of code channels. A code channel, that is, a code division channel, divides a channel into a plurality of code channels by a plurality of different spreading codes. The spreading code may be, for example, a variable order Walsh code (Walsh code), which is also called an Orthogonal Variable Spreading Factor (OVSF). The variable order Walsh code is a set of orthogonal spreading codes, and the order thereof, also called a spreading factor, may be 2, 4, 6, 8, ... 256. When the spreading factor is k, k is an integer greater than zero, and there are k fully orthogonal spreading codes, then the ith spreading code in the k fully orthogonal spreading codes can be expressed, for example, 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 solution of the foregoing embodiment includes the service data of the uplink data channel transmitted through the target code channel and the 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.

Sending uplink information to the network side device by using the target code channel, and actually transmitting the information in the target code channel For a portion of the uplink information, ie, the first information, another portion of the uplink information, ie, the second information, that is, the control information, is characterized by a channelization code of the target code channel. Thus, the power required to actually transmit the uplink information is the power required to transmit the first information, and the second information does not require additional transmission power. Therefore, the solution in this embodiment reduces the transmission power required to transmit uplink information, thereby improving the uplink throughput of the UE.

FIG. 2 is a flowchart of a method for transmitting uplink control information according to Embodiment 2 of the present invention. The second embodiment of the present invention further provides a method for transmitting uplink control information. The execution body of the method step in this embodiment is a network side device, and the following operations may be implemented by hardware, software, or a combination of hardware and software. The method of this embodiment includes the following steps:

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

Step 201: If the first information is detected on the code track of the multiple code channels, acquire 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, and may be, for example, a base station. The network side device can be used to convert the received air frame to the IP packet as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network can include an Internet Protocol (IP) network. The network side device can also coordinate the attribute management of the air interface. The network side device may be, for example, a base station, and the base station may be a base station (BTS, Base Transceiver Station) in CDMA, or may be 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 the preset multiple code channels, that is, detects one by one for multiple code channels to see whether the information sent by the UE is received.

When the information is detected on one of the code channels, that is, the first information, the continuation of the detection is stopped, the first information is part of the uplink information sent by the user equipment, and the channel from the code channel is obtained according to the channelization code of the code channel. The second information of the characterization. So far, the network side device receives all the uplink information sent by the UE.

The method for transmitting the uplink control information according to the second embodiment of the present invention is the implementation method of the receiving end corresponding to the method for transmitting the uplink control information provided in the first embodiment, and the specific beneficial effects thereof are similar to the beneficial effects of the first embodiment. This will not be repeated here.

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

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

As shown in FIG. 3, the method in this embodiment includes the following steps:

Step 300: The UE determines, according to the preset number of code channels, the number of control information that the channelization code can carry, and further determines control information carried by the channelization code.

The control information transmitted by the target code channel is part of the control information of the control information sent by the uplink control channel, and the first control information indicates that the uplink control information carried by the channelization code of the target code channel is the control information sent by the uplink control channel. Another part of the control information is represented by the second control information. In this step, the determined control information carried by the channelization code, that 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, wherein the channelization codes of the plurality of code channels respectively correspond to different information bits.

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

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, a dedicated physical control channel (Dedicated Physical Control Channel, abbreviated DPCCH), which mainly carries the pilot bit (Pilot bit) and the Transmission Power Control (TPC) information required for channel estimation by the network side device; if the UE needs to send services such as voice, the DPCCH will also The transport format combination indicator (TFCI) information of the service such as the voice is transmitted; 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 further include the acknowledgement acknowledgement ACK information.

The enhanced Dedicated Physical Control Channel (E-DPCCH) is mainly used to carry control information sent by the UE to the network side device, including the High Speed Uplink Packet Access (HSUPA) service, including The Retransmission Sequence Number (RSN), the Happy Bit and the Enhanced Transport Format Combination Indicator (E-TFCI) information, and the like.

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 device, such as confirmation. Acknowledgement (ACK) information and Negative Acknowledgement (NACK) information, and Channel Quality Indicator (CQI) information.

When the UE simultaneously transmits at least two types of uplink control information to the network side device, different uplink control channels correspond to different code channels, and channelization codes of different multiple code channels are different, and control information of different uplink control channels is different. Different, therefore, different uplink control channels also correspond to mapping relationships between different channelization codes and control information.

When the uplink control channel is an 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

Specifically, the larger the number of bits of the second information, the smaller the number of bits of the first information, and the smaller the transmission power used by the UE to transmit the first information. 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. 4 is a schematic diagram of a channel format of an E-DPCCH according to Embodiment 3 of the present invention. As shown in FIG. 4, when one radio subframe of the E-DPCCH includes 15 slots, slot #0, slot #1, ... Gap #14, each Transmission Timing Interval (TTI) needs to transmit 10 bits of control information, which is encoded into a 30-bit data stream and transmitted on one radio subframe. The 10-bit control information includes the following three parts:

2-bit RSN;

A 1-bit Happy Bit, when Happy Bit=1, indicates that the UE wants to acquire more uplink transmission resources;

A 7-bit E-TFCI indicating the size of the transport block transmitted by the UE in each wireless subframe.

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

The number of bits of the control information that can be carried by the channelization code is greater than the number of bits of the RSN and the Happy Bit, but is smaller than the number of bits of the E-TFCI, because the number of bits of the E-TFCI is relatively large. For example, if the preset code channel is 32 code channels, it can be determined that the channelization code can represent 5 bits of control information, and the content of the second information is all control information or partial control information of a function. In order to characterize more control information on the channelization code to reduce the control information transmitted on the target code channel and reduce the transmission power of the transmission control information, it is possible to determine that the second information is a 5-bit E-TFCI. If the preset code channel is 6 code channels, it can be determined that the channelization code can represent 2 bits of control information, and the second information is a 2-bit RSN.

If the E-TFCI is transmitted in the HSUPA service, at least 128 uplink code channels are required. When the channelization code of the code channel in the preset code channel is insufficient to carry the complete 7-bit E-TFCI, The E-TFCI performs bit reduction, and then the second information content may include reduced E-TFCI information, and the first information includes RSN and/or Happy Bit.

If in the HSUPA service, the network side device has a data service grid sent by the blind user equipment. The ability of the user equipment can stop the transmission of the E-TFCI, then the second information can include the RSN, and the first information includes Happy Bit. For example, the UE can use four code channels to characterize the four types of information of the RSN and send a 1-bit Happy Bit on the code track.

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

The first information includes a Pilot and/or a TPC, and the second information is a first acknowledgment ACK or a first acknowledgment 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 large, the UE may correctly decode the voice service data after receiving a part of the information of the current radio frame, and then the current frame is A part of the voice information does not need to be received again. At this time, the DPCCH control information sent by the UE may further include a first acknowledgement acknowledgement ACK information or a first unacknowledged acknowledgement NACK, and the first acknowledgement acknowledgement ACK is sent to notify the network side device. The UE has correctly decoded the required voice data, and instructs the network side device to terminate the voice service sent in the current frame in advance, saving time-frequency resources for receiving the voice information of the latter part of the current frame, and alleviating the UE and the network side. The burden of the equipment.

It should be noted that the first acknowledgement response ACK here is different from the ACK in the automatic retransmission acknowledgement, and the first acknowledgement acknowledgement ACK is used to instruct the receiving end to terminate the voice service subsequently sent by the current frame in advance, and to automatically retransmit the response. The middle ACK is used to instruct the receiving end to continue to transmit 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, and details are not described herein again.

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

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

Further, if the UE has a certain capability of canceling the downlink interference of the neighboring cell, the UE may include the CQI identifier in the second information, and the current CQI value is represented by the CQI identifier before the channel interference caused by the neighboring cell is eliminated. The calculation is obtained, or the interference is obtained after the interference is eliminated, so that the network side device can more accurately schedule downlink data for the UE.

The method for determining the second information of the HS-DPCCH is similar to the method for determining the second information of the E-DPCCH, and details are not described herein again.

Determining the target code channel in the plurality of code channels according to the content of the control information carried by the channelization code, that is, the content of the second control information, which may be through a mapping table or a database in a preset channelization code and control information. Matching 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 one target code channel can be determined from the plurality of code channels to transmit the control channel A control message.

In spreading factor of 256 for the code channel units, assuming four yards preset channel, then the channel may be a four yards _{_{C ch, 256,1, C ch,}} 256,2, C ch, 256,3, C _{Ch, 256, 4} , then it can be determined that the control information that can be characterized by the channelization code is 2 bits of control information. When the control information that the UE needs to transmit is the control information of the E-DPCCH, the second control information is a 2-bit RSN, and then the first information is 8-bit control information, that is, a 1-bit Happy Bit and a 7-bit E-TFCI.

Step 301: The UE determines, according to the control information of the channelization code bearer determined in step 301, a target code channel from the plurality of code channels to carry the first information to be sent.

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 plurality of code channels respectively correspond to different information.

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

It should be noted that, in the implementation scenario that 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 as the target code channel in the preset multiple code channels.

Further, before step 300, the method further includes:

Step 300a: The user equipment receives the second configuration signaling sent by the network side device, where 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 portion of the control information for the uplink control channel carried.

Alternatively, before step 300, the method further includes:

Step 300b: The user equipment determines, according to at least one of a current usage state of the current code channel and a currently scheduled service state, the multiple code channels corresponding to the uplink control channel, and the channelization code of the multiple code channels. The other portion of the uplink control channel carried by the control information.

Specifically, before determining the target code channel from the multiple code channels, the UE needs to know the control information of the channel code of the multiple code channels and code channels corresponding to the sent uplink control channel. The control information that can be carried by the multiple code channels and the channelization code of the code channel may be a plurality of code channels corresponding to the current uplink control channel that are configured by the second configuration signaling sent by the network side device, and the code channel. The channelization code is used to carry control information. The second configuration signaling includes Radio Resource Control (RRC) signaling.

The network side device may determine the code channel and another part of the control information of the uplink control channel for the bearer according to at least one of a current state of use of the code channel and a service state to be scheduled. Specifically, the channel information of multiple code channels and code channels corresponding to multiple different uplink control channels is pre-configured on the UE side for the bearer control information, and the UE uses the current code channel usage status and the currently scheduled service status. And selecting at least one of the plurality of code channels corresponding to the uplink control channel and another part of the control information for the uplink control channel for the bearer.

The state of use of the current code channel, that is, the state of the code channel of the physical channel currently used for uplink transmission and/or the size of data of the uplink service transmitted on the corresponding code channel, and the like. The UE may determine the control information of the uplink control channel that needs to be sent according to the current scheduled service state, and then determine the control information of the channelization code bearer of the multiple code channels and code channels corresponding to the uplink control channel.

When the UE is in different working states, such as the type or number of service data transmitted or received, using different methods to transmit or receive data, etc., the usage status of the code channel is different.

The spreading factors used by different physical channels may be different. The size of the spreading factor determines the size of the service data or control information transmitted on the physical channel, the transmission rate, and the accuracy of the information. 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 higher accuracy, and the transmission rate is lower, usually a larger selection is required. Spreading factor. For example, when transmitting a signal through the DPDCH, the spreading factor is 4 to 256; When the signal is transmitted through the HS-DPDCH, the spreading factor is 128 to 256; when the signal is transmitted through the E-DPDCH, the spreading factor is 2 to 256. In the embodiment of the present invention, the spreading factor 256 is used as the code channel unit, that is, it is assumed that the UE has 256 code channels.

For example, when the UE transmits only voice and/or data and its corresponding control information, the rest of the situation is not considered. The DPDCH is used as the physical layer basic service bearer channel in the UMTS system. The UE transmits DPDCH data using 6 code channels, which are respectively transmitting the in-phase and quadrature signals, each occupying 3 code channels, respectively, using C _{ch, 4} , ₁ , C _{ch, 4,2} , C _ch,4,3 , C _ch,4,1 , C _ch,4,2 , C _ch,4,3 respectively represent 64 code channels with a spreading factor of 256; the UE will use one code channel The control information of the HS-DPCCH is transmitted, and the code channel C _{ch, 256, 1} ; and the UE transmits the control information of the DPCCH through the code channel C _{ch, 256, 0} in any case. The UE has 256 physical code channels, and in this case, the UE still has at least 62 code channels unused.

When the UE is in other situations, the calculation method of the at least the number of unused code channels is similar to the above calculation method and explanation, and details are not described herein again.

A method of determining a code channel, for example, when a UE transmits uplink voice service data through high-speed uplink packet access, a voice for an adaptive multi-rate speech coding algorithm, referred to as AMR voice, due to its The data is generally small, using a spreading factor of 128 and using the code channel C _ch, 128 _{, 32} . For video telephony data, the transmission rate, that is, the continuity of video passing is generally high, and the spreading factor is smaller, 32, and the code channel used is C _ch, 32, 8. Here, the spreading factor is 256 for the code channel unit, that is, the physical code channel for uplink transmission is 256 code channels. Channelization code C _{ch, 128,32} the code channel with spreading factor of 256 by a channelization code indicated as C _{ch, 256,64,} channelization code C _{ch, 32,8} of code channels with spreading The channelization code represented by the frequency factor of 256 is C _{ch, 256, 64} . Control information transmission code channel DPCCH is used as C _{ch, 256,0,} then the UE may be agreed in advance to use C _{_ch,} 256,1 ~ C _ch, _256,63 any of K th code channel as E-DPCCH corresponding to Multiple code channels.

When the UE transmits uplink service data through multiple input multiple output (MIMO), the code channel used for transmitting the control information of the DPCCH is C _{ch, 256} , ₀ , and the code channel used for transmitting the control information of the S-DPCCH is C _{ch , 256, 31} , the code channel used for transmitting the control information of the HS-DPCCH is C _{ch, 128, 16} , and the code channel used for transmitting the control information of the 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 the UE can be pre-agreed to use C _{ch, 256} _{, 1} ~ C _{ch, 256, 30} and C _ch, Any K code channels of ₂₅₆ , ₃₃ to C _{ch, 256, 63} are used as a plurality of code channels corresponding to the E-DPCCH.

In other cases, the method for determining a plurality of code channels corresponding to the uplink control channel is as described above. The method and explanation are similar and will not be repeated here.

The method for the channelization code of the code channel to be used for the control information may be determined according to the mapping relationship between the channelization code of the code channel transmitted by the network side device or the code channel established by the network side device and the control information. In the mapping relationship between the channelization code of the code channel and the control information, the channelization code corresponds to the second information one by one. For example: RSN 2bit is 00, the corresponding channelization codes may be, for example, C _ch, 256,1; 2bit the RSN 01, the corresponding channelization codes may be, for example, _{C ch,} 256,2; 2bit the RSN 10, The corresponding channelization code may be, for example, C _{ch, 256, 3} ; the RSN of 2 bits is 11, and the corresponding channelization code may be, for example, C _{ch, 256, 4} .

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

Step 302: The UE sends the 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 one by one on a preset plurality of code channels to obtain a part of information of the uplink control channel, that is, the first information.

The network side device detects one by one on a preset plurality of code channels. When the code channel is 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 a certain code channel, the second information is obtained according to the channelization code of the code channel, so that the complete control information of the uplink control channel is obtained.

The network side device detects and decodes the first information, that is, the 8-bit E-DPCCH, on a certain code channel of the preset multiple code channels, and obtains the channelization code of the code channel as C _{ch, 256} , 3 . Therefore, according to the mapping relationship between the channelization code of the code channel and its corresponding control information, another 2 bit RSN of the E-DPCCH can be obtained, thereby obtaining a complete 10-bit E-DPCCH.

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

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

Step 500: The UE determines, according to the control information corresponding to the uplink data channel, and the channelization code of the preset code channel, the at least one code channel as the target code channel to carry the to-be-transmitted control information. Service data transmitted 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 large, the multiple code channels configured to transmit the service data of the uplink data channel are in an idle state, and the service of the uplink data channel is transmitted. The code channel of the data may have more than one code channel. At this time, the channelization code of the code channels can carry the control information corresponding to the uplink data channel, so as to reduce the power of directly transmitting the control information corresponding to the uplink data channel. The UE may determine at least one code channel as the target code channel to transmit the service data corresponding to the uplink data channel in the preset multiple code channels, and carry the control information corresponding to the uplink data channel by using the channelization codes of the code channels.

Further, wherein 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

Specifically, when the service data HSUPA service data transmitted by the UE, the HSUPA service data is usually sent by using an Enhanced Dedicated Physical Date Channel (E-DPDCH). In the prior art, when transmitting E-DPDCH data, the UE must simultaneously transmit control information of the E-DPCCH, such as E-TFCI. In this solution, when the amount of data transmitted by the E-DPDCH is not large, the control information of the E-DPDCH part is carried by the channelization code of the code channel of the E-DPDCH data when the E-DPDCH data is transmitted, for example, when When the size or format of the transmitted data block is complicated, the E-TFCI may be carried by the channelization code to indicate the data block size in the E-DPDCH, and the E-TFCI is transmitted without the code channel transmission information, thereby saving transmission. The transmit power used by the E-TFCI; or, when the transmitted data block is a retransmitted data block, the RSN may be carried by the channelization code to enable the network side device to determine the retransmitted data block according to the RSN; or, send the E-DPDCH After the network side device allocates the resources to the UE, the channelization code can only carry the Happy Bit to inform the network side device whether the allocated resources are satisfactory, and the RSN and/or Happy Bit are sent without using the code channel transmission information. Thus, the transmission power used to transmit the RSN and/or Happy Bit is saved.

Due to the format of E-DPDCH data, data feedback and/or retransmission of retransmissions at each TT1 The allocation of the source may change, so E-TFCI, RSN and/or Happy Bit may also change in the control information of the corresponding E-DPCCH in different TTIs.

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

Step 500a: The UE receives the first configuration signaling sent by the network side device, where the first configuration signaling is used to indicate the multiple code channels corresponding to the uplink data channel, and channelization of the multiple code channels The code is used to carry 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, according to at least one of a current state of use of the code channel and a currently scheduled service state, the multiple code channels corresponding to the uplink data channel, and channelization codes of the multiple code channels are used. Control information corresponding to the uplink data channel carried.

The first configuration signaling includes RRC signaling. Determining, by the plurality of code channels corresponding to the uplink data channel, the channelization code of the plurality of code channels, the control information corresponding to the uplink data channel of the bearer, and determining the multiple codes corresponding to the different uplink control channels in the foregoing Embodiment 3. The process of using channelization codes of multiple channels and multiple code channels for carrying control information is similar, and details are not described herein again.

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.

Step 502: The network side device detects one by one on a preset plurality of code channels to obtain service data of the uplink data channel.

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

In the embodiment of the present invention, when the service data of the uplink data channel is transmitted, the at least one target code channel is determined and the service data of the uplink data channel is sent, and the channelized code of the at least one target code channel is used to carry the corresponding uplink data channel. The control information does not need to transmit the control information of the uplink data channel through the dedicated control channel, reduces the transmission power for transmitting the control information, and improves the uplink throughput of the UE.
