Background

In a mobile communication network system, whether a User Equipment (UE) sends uplink data to a network side or sends downlink data to the UE, some control channels are usually sent along with the User Equipment. The control channels include pilot signals, data format indications, channel quality indications, and other control information necessary for demodulation of decoded data. The network side can decode the received data sent by the UE to obtain the data only on the premise of correctly receiving the control channel. Similarly, the UE can decode the received data sent by the network side to obtain the data only on the premise of receiving the control channel.

Detailed Description

In order to make the objects, 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 with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The techniques described herein may be used in a variety of third generation mobile communication systems, such as Code Division Multiple Access (CDMA) systems, Wideband Code Division Multiple Access (WCDMA) systems, Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) systems, and other such communication systems.

Fig. 1 is a flowchart of a method for transmitting uplink control information according to an embodiment of the present invention. The following steps are executed by the UE, and specifically, the following operations may be implemented by hardware, software, or a combination of hardware and software. The method of the embodiment comprises the following steps:

step 100, determining a target code channel from a plurality of preset code channels.

Step 101, sending uplink information to a network side device by using the target code channel, wherein the uplink information includes: the information bits transmitted by the target code channel bear the first information, and the channelization codes of the target code channel bear the second information.

A UE referred to in this application is a wireless terminal, which may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (e.g., RAN). For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User agent (User agent), a User Device (User Device), or a User Equipment (User Equipment).

The code channel refers to: in a physical channel used for uplink transmission, UE occupies the remaining unoccupied code channels except for a certain number of code channels occupied by sending service data or other control information. The code channels, i.e., code division channels, are divided into a plurality of code channels by a plurality of different spreading codes. The spreading code may be, for example: walsh codes of Variable order (also known as Orthogonal Variable Spreading Factors (OVSF) codes are known. The variable Walsh codes are a set of orthogonal spreading codes whose 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, there are k completely orthogonal spreading codes, and then the ith spreading code of the k completely orthogonal spreading codes may be represented as C, for example_ch,k,i. Using spreading codes as C_ch,k,iThe code channel has a channelization code of C_ch,k,i。

The above embodiment includes two implementation scenarios, i.e., 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.

The method comprises the steps of utilizing a target code channel to send uplink information to network side equipment, wherein information actually transmitted in the target code channel is part of the uplink information, namely first information, and the other part of the uplink information, namely second information, namely control information, is represented by a channelization code of the target code channel. Thus, the power required for actually transmitting the uplink information is the power required for transmitting the first information, and the second information does not need additional transmission power. Therefore, the scheme of the embodiment reduces the transmission power required for transmitting the 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 a second embodiment of the present invention. The second embodiment of the present invention further provides a method for transmitting uplink control information, where an execution main body of the method steps in this embodiment is a network side device, and the following operations may be specifically implemented by hardware, software, or a combination of hardware and software. The method of the embodiment comprises the following steps:

step 200, detecting first information sent by user equipment on a plurality of preset code channels.

Step 201, if the first information is detected on a code channel of the plurality of code channels, acquiring second information carried by a 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.

In particular, a network side device may refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals, and may be, for example, a base station. The network-side device may be configured to interconvert received air frames and IP packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. The network side device may also coordinate attribute management for the air interface. The network side device may be, for example, a Base Station, and the Base Station may be a Base Transceiver Station (BTS) in CDMA, or a Base Station (NodeB) in WCDMA or TD-SCDMA, and the present application is not limited thereto.

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

And when information detected on one code channel is first information, stopping continuous detection, wherein the first information is a part of uplink information sent by user equipment, and acquiring second information represented by the channelization codes of the code channel according to the channelization codes of the code channel. At this point, the network side device receives all uplink information sent by the UE.

The method for transmitting uplink control information according to the second embodiment of the present invention is a method for implementing a receiving end corresponding to the method for transmitting uplink control information according to the first embodiment, and has specific beneficial effects similar to those of the first embodiment, which are not described herein again.

Fig. 3 is a flowchart of a method for transmitting uplink control information according to a third embodiment of the present invention. The embodiment provides a specific interaction process between the UE and the network side device in an implementation scenario that the UE sends the control information of the control channel through the target code channel when sending the uplink information to the network device.

Further, in the foregoing embodiment, if the first information is a part 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 of the present embodiment includes the following steps:

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

The control information transmitted by the target code channel is part of control information of the control information sent by the uplink control channel, and is represented by first control information, and the uplink control information carried by the channelization code of the target code channel is the other part of control information of the control information sent by the uplink control channel, and is represented by second control information. In this step, the determined control information carried by the channelization code is the second control information. Therefore, the information carried by the channelization codes 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 channel may be a part of all idle code channels used by the UE for uplink transmission, or may be all idle code channels. Here, the idle code channels refer to the remaining unoccupied code channels except the code channels occupying a certain amount for transmitting the service data or other control information in the physical channel used for uplink transmission by the UE. Then the number of the preset code channels is less than or equal to the number of all idle code channels of the UE. Suppose that the number of the predetermined code channels is N, and N is expressed as a power of 2, i.e. 2, with the base number being 2^XN is known, the exponent X can be obtained by a series expansion, for example by taylor's expansion. The X may be an integer or a decimal. When X is an integer, determining that the second control information can be control information of X bit; when X is a decimal, it is determined that the second control information may be control information of an integer part bit of X, or control information of N kinds of non-integer bits. The control channel includes a plurality of control information of different functions, the control information of different functions has different sizes, and the second control information is control information of one function, which may be all control information or part control information of one function, or a combination of control information of multiple functions.

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

a special physical control channel DPCCH, an enhanced special physical control channel E-DPCCH and a high-speed special physical control channel HS-DPCCH; different control channels correspond to different multiple code channels.

Specifically, a Dedicated Physical Control Channel (DPCCH) is mainly used for carrying Pilot bits (Pilot bits) required for Channel estimation by a network side device and Transmission Power Control (TPC) information; if UE needs to send voice service, Transmitting Format Combination Indicator (TFCI) information of voice service is transmitted on 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 further include an acknowledgement ACK information.

An Enhanced Dedicated Physical Control Channel (E-DPCCH), which mainly carries Control information sent by a UE to a network side device under a High Speed Uplink Packet Access (HSUPA) service, includes Retransmission Sequence Number (RSN), Happy Bit, and Enhanced transport Format Combination Indicator (E-TFCI) information, etc.

A High Speed Dedicated Physical Control Channel (HS-DPCCH) mainly carries reception status information of a Hybrid automatic repeat reQuest (HARQ) sent by the UE to the network side device, such as Acknowledgement (ACK) information, Negative Acknowledgement (NACK) information, and Channel Quality Indicator (CQI) information.

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

When the uplink control channel is E-DPCCH, the second information comprises a retransmission sequence number RSN and/or Happy Bit, and the first information comprises an enhanced transport format combination indicator (E-TFCI); or

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

a 2-bit RSN;

a Happy Bit of 1Bit, when Happy Bit =1, indicating that the UE wishes to acquire more uplink transmission resources;

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

For example, if the predetermined code channels are 2 code channels, the second information is a Happy Bit of 1Bit, and the first information is RSN and E-TFCI; if the preset code channels are 4 code channels, the second information is RSN with 2 bits, and the first information is Happy Bit and E-TFCI; if the preset multiple code channels are 2^xAnd if the code channel is 2 < x < 7, the second information is the E-TFCI of x bits, and the first information comprises Happy Bit, RSN and the residual E-TFCI of 7-x bits.

Because the Bit number of the E-TFCI is larger, when the UE determines that the Bit number of the control information which can be carried by the channelization codes is larger than the Bit number of the RSN and the Happy Bit and smaller than the Bit number of the E-TFCI according to the number of the preset code channels, for example, if the preset code channels are 32 code channels, the control information of which the channelization codes can represent 5 bits can be determined, and the content of the second information is all control information or part of control information of one function. In order to represent more control information on channelization codes as much as possible, so as to reduce the control information transmitted on a target code channel and reduce the transmission power for transmitting the control information, the E-TFCI in which the second information is 5 bits can be determined. If the preset code channel is 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 an integer number of bits of E-TFCI are sent in HSUPA service, at least 128 uplink code channels are needed, when the channelization codes of the code channels in the preset code channels are not enough to bear a complete 7-bit E-TFCI, the E-TFCI can be further subjected to bit reduction, the second information content can comprise the reduced E-TFCI information, and the first information comprises RSN and/or HappyBit.

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

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

The first information comprises Pilot and/or TPC, and the second information is first acknowledgement ACK or first non-acknowledgement NACK. And the ACK is used for indicating 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, because 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 voice information of the latter part of the current frame does not need to be received again, and at this time, the DPCCH control information sent by the UE may also include a first acknowledgement ACK or a first non-acknowledgement NACK, and the first acknowledgement ACK is sent to inform the network side device that the UE has correctly decoded the required voice data, and to instruct the network side device to terminate the voice service sent at the current frame in advance, thereby saving time-frequency resources for receiving the voice information of the latter part of the current frame, and reducing the burden of the UE and the network side device.

It should be noted that, unlike the ACK in the automatic repeat request, the first ACK is used to instruct the receiving end to terminate the voice service subsequently sent by the current frame in advance, and the ACK in the automatic repeat request is used to instruct the receiving end to continue sending subsequent data. The method of determining the second information of the DPCCH is similar to the method of determining the second information of the E-DPCCH described above and is not described herein again.

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

Specifically, if the network side device does not send downlink data at the previous time, the UE does not need to send an HARQ indication, and at this time, if a CQI needs to be transmitted, the first control information does not have a message to be transmitted, so the UE needs to send a fixed bit sequence as the first information.

Further, if the UE has a certain capability of eliminating downlink interference of the neighboring cell, the UE may include a CQI identifier in the second information, and the CQI identifier represents whether the currently reported CQI value is obtained by calculation before eliminating channel interference caused by the neighboring cell or obtained by calculation after eliminating the interference, so that the network side device can more accurately schedule downlink data to the UE.

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

The target code channel is determined in the multiple code channels according to the content of the control information carried by the channelization code, that is, the content of the second control information, where the content of the second control information is searched in a mapping relation table or a database of preset channelization codes and control information in a matching manner, and 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 multiple code channels to transmit the first control information of the control channel.

Assuming that the spreading factor is 256 as a unit of code channels, and 4 code channels are preset, the 4 code channels may be C_ch,256,1、C_ch,256,2、C_ch,256,3、C_ch,256,4Then it can be determined that the control information that can be characterized by the channelization codes is 2-bit control information. When the control information required to be transmitted by the UE is the control information of the E-DPCCH, the second control information is the RSN with 2 bits, and the first information is the control information with 8 bits, namely the Happy Bit with 1Bit and the E-TFCI with 7 bits.

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

The channelization codes of the target code channel bear information and information of the second information, wherein the channelization codes of the plurality of code channels respectively correspond to different information.

Since the control information of the uplink control channel transmitted in each TTI may change, the control information carried by the channelization code in each TTI may also change, and therefore, in a certain TTI, when the control information of the uplink control channel to be transmitted changes, the target code channel 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 as the target code channel from a plurality of preset code channels.

Further, before step 300, the method further includes:

step 300 a: and the user equipment receives a second configuration signaling sent by the network side equipment, wherein the second configuration signaling is used for indicating the plurality of code channels corresponding to the uplink control channel and the other part of control information of the uplink control channel, which is carried by the plurality of code channels.

Alternatively, before step 300, further comprising:

step 300 b: and the user equipment determines the plurality of code channels corresponding to the uplink control channel and the other part of control information of the uplink control channel, which is carried by the channelization codes of the plurality of code channels, according to at least one of the using state of the current code channel and the current scheduling service state.

Specifically, before determining the target code channel from the multiple code channels, the UE needs to know the multiple code channels corresponding to the transmitted uplink control channel and the control information that the channelization codes of the code channels are used for carrying. The multiple code channels and the control information that can be carried by the channelization codes of the code channels may be one or more code channels that are configured by a second configuration signaling sent by the network side device and that currently need to send an uplink control channel, and the channelization codes of the code channels are used for carrying the 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 control information of the uplink control channel for bearer according to at least one of the usage state of the current code channel and the service state that needs to be scheduled. Specifically, a plurality of code channels corresponding to a plurality of different uplink control channels and channelization codes of the code channels for carrying control information may be preconfigured on the UE side, and the UE selects a plurality of code channels corresponding to the uplink control channels and another part of control information of the uplink control channels for carrying according to at least one of the current usage state of the code channels and the current scheduling service state.

The current code channel usage status, 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 current scheduling service state, the UE can determine the control information of the uplink control channel to be sent, and then determine a plurality of 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 amount of the transmitted or received service data, and the data is transmitted or received in different manners, the use states of the code channels are different.

The spreading factor used by different physical channels may be different, and the size of the spreading factor determines the size, transmission rate and information accuracy requirements of the traffic data or control information transmitted on the physical channel. When the content of transmitted information is small and the requirement on the accuracy of the information is not high, a small spread spectrum factor is usually selected; when the information to be transmitted has a high requirement on accuracy and a low requirement on transmission rate, a large spreading factor is usually selected. For example, when the signal is transmitted through the DPDCH, the spreading factor is 4-256; when the signal is transmitted through the HS-DPDCH, the spreading factor is 128-256; when the signal is transmitted through the E-DPDCH, the spreading factor is 2-256. In the embodiment of the present invention, the spreading factor 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, the rest of the cases are not considered. DPDCH as UMTS systemIn the physical layer basic service bearer channel, the UE sends DPDCH data by using 6 code channels, respectively sending in-phase and orthogonal signals respectively occupying 3 code channels, and respectively using C_ch,4,1、C_ch,4,2、C_ch,4,3，C_ch,4,1、C_ch,4,2、C_ch,4,3Respectively representing 64 code channels with the spreading factor of 256; the UE may transmit control information for the HS-DPCCH using one code channel, code channel C_ch,256,1(ii) a And the UE passes through the code channel C under any condition_ch,256,0Control information of the DPCCH is transmitted. All the physical code channels of the UE are 256, so in this case, at least 62 code channels of the UE are still unused.

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

A method for determining code channel, for example, when UE transmits uplink voice service data through high speed uplink packet access, for voice of Adaptive Multi-Rate (Adaptive Multi-Rate) voice coding algorithm, referred to as AMR voice for short, because the data is generally small, the used spreading factor is 128, and the used code channel is C_ch,128,32. For video telephony data, the transmission rate, i.e. the continuity of the video channel, is generally high, the spreading factor is smaller, i.e. 32, and the code channel C is used_ch,32,8. The spreading factor is 256, i.e. the physical code channels for uplink transmission are 256 code channels. Channelisation code of C_ch,128,32Code channel of (2), channelization code C represented by spreading factor of 256_ch,256,64Channelisation code of C_ch,32,8Code channel of (2), channelization code C represented by spreading factor of 256_ch,256,64. The code channel used for transmitting the control information of DPCCH is C_ch,256,0Then the UE may be pre-agreed to use C_ch,256,1～C_ch,256,63Any K code channels in the E-DPCCH are used as a plurality of code channels corresponding to the E-DPCCH.

Transmitting control information of DPCCH when UE transmits uplink traffic data through a multiple-input multiple-output (MIMO) schemeThe code channel used is C_ch,256,0The code channel used for transmitting the control information of the S-DPCCH is C_ch,256,31The code channel used for transmitting the control information of the HS-DPCCH is C_ch,128,16The code channel used for transmitting the control information of the S-E-DPCCH is C_ch,4,1，C_ch,128,16Can be represented as C_ch,256,32，C_ch,4,1Can be represented as C_ch,256,64Then the UE may be pre-agreed to use C_ch,256,1～C_ch,256,30And C_ch,256,33～C_ch,256,63Any K code channels in the E-DPCCH are used as a plurality of code channels corresponding to the E-DPCCH.

In other cases, the determination method of the multiple code channels corresponding to the uplink control channel is similar to the determination method and the explanation shown above, and is not repeated here.

The method for using the channelization code of the code channel for carrying the control information may be determined according to a mapping relationship between the channelization code of the code channel and the control information sent by the network side device or established by the network side device. In the mapping relationship between the channelization codes and the control information of the code channels, the channelization codes correspond to the second information one to one. For example: the RSN of 2 bits is 00 and the corresponding channelization code may be C, for example_ch,256,1(ii) a The RSN of 2 bits is 01, and the corresponding channelization code may be C, for example_ch,256,2(ii) a The RSN of 2 bits is 10, and the corresponding channelization code may be C, for example_ch,256,3(ii) a The RSN of 2 bits is 11, and the corresponding channelization code may be C, for example_ch,256,4。

When the RSN of 2bit is 10, the target code channel can be determined as channelization code C according to the mapping relationship between the channelization code and the control information of the code channel_ch,256,3The corresponding code channel.

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

I.e. in channelization code C_ch,256,3And sending the code channel to the network side equipment.

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

The network side device detects the code channels one by one on a plurality of preset code channels, and when the code channels are 4 code channels, the 4 code channels can be detected one by one according to the size of the channelization codes.

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

The network side equipment detects and decodes on a certain code channel of a plurality of preset code channels to obtain first information, namely 8-bit E-DPCCH, and simultaneously can obtain the channelized code C of the code channel_ch,256,3Therefore, the RSN of the other 2 bits of the E-DPCCH can be obtained according to the mapping relation between the channelization codes of the code channels and the corresponding control information, and the complete E-DPCCH with 10 bits is obtained.

In the embodiment of the present invention, the UE determines a target code channel from a plurality of preset code channels to send the first information by determining the first information and the second information of different uplink control channels, and the channelization code of the target code channel carries the second information, so as to reduce the sending power of the UE for sending the control information of the uplink control channel, improve the control information for sending uplink service data, and improve the uplink throughput of the UE.

Fig. 5 is a flowchart of a method for transmitting uplink control information according to a fourth embodiment of the present invention. The 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 an uplink data channel to the network side device on a target code channel. The method of the embodiment comprises the following steps:

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

Specifically, when the amount of the service data of the uplink data channel transmitted by the UE is not large, the configured multiple code channels for transmitting the service data of the uplink data channel may be in an idle state, and there may be more than one code channel for transmitting the service data of the uplink data channel, and at this time, the channelization codes of the code channels may carry the control information corresponding to the uplink data channel, so as to reduce the power for directly transmitting the control information corresponding to the uplink data channel. The UE may determine at least one code channel among the preset code channels as a target code channel to transmit service data corresponding to the uplink data channel, and bear control information corresponding to the uplink data channel by channelization codes of the code channels.

Furthermore, 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 UE transmits the service data HSUPA service data, the HSUPA service data is usually transmitted through an Enhanced Dedicated Physical data 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. According to the scheme, when the data volume of the E-DPDCH is not large, the E-DPDCH data can be transmitted, the control information of the E-DPDCH part is carried by the channelized code of the code channel for transmitting the E-DPDCH data, for example, when the size or the format of a transmitted data block is complex, the E-TFCI can be carried by the channelized code to indicate the size of the data block in the E-DPDCH, and the E-TFCI is transmitted without transmitting information through the code channel, so that the transmitting power for transmitting the E-TFCI is saved; or, when the transmitted data block is a retransmission data block, the RSN may be carried by a channelization code so that the network side device may determine the retransmission data block according to the RSN; or after the data of the E-DPDCH is sent to the network side equipment to allocate resources to the UE, the UE can only bear the Happy Bit through the channelization code to inform the network side equipment whether the allocated resources are satisfied, and the RSN and/or the Happy Bit are sent without transmitting information through the channelization code, so that the sending power used for sending the RSN and/or the Happy Bit is saved.

Since the format of the transmitted E-DPDCH data, the data feedback for retransmissions, and/or the allocation of resources may vary per TT1, the E-TFCI, RSN, and/or HappyBit in the control information of its corresponding E-DPCCH may also vary in different TTIs.

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

step 500 a: and the UE receives a first configuration signaling sent by network side equipment, wherein the first configuration signaling is used for indicating the plurality of code channels corresponding to the uplink data channel, and the channelization codes of the plurality of code channels are used for bearing control information corresponding to the uplink data channel.

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

step 500 b: and the UE determines the plurality of code channels corresponding to the uplink data channel and the control information corresponding to the uplink data channel, which is carried by the channelization codes of the plurality of code channels, according to at least one of the using state of the current code channel and the current scheduling service state.

The first configuration signaling comprises RRC signaling. The process of determining the multiple code channels corresponding to the uplink data channel and the control information corresponding to the uplink data channel that the channelization codes of the multiple code channels are used to carry is similar to the process of determining the multiple code channels corresponding to different uplink control channels and the channelization codes of the multiple code channels are used to carry the control information in the third embodiment, and details are not repeated here.

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 plurality of preset code channels 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, acquiring, according to the channelization code of the at least one code channel, control information corresponding to the uplink data channel, where the channelization code of the at least one channel is used for bearing.

In the embodiment of the invention, when the service data of the uplink data channel is transmitted, at least one target code channel is determined and the service data of the uplink data channel is transmitted, the control information corresponding to the uplink data channel is carried by the channelized code of the at least one target code channel, and the control information of the uplink data channel does not need to be transmitted through a special control channel, so that the transmission power for transmitting the control information is reduced, and the uplink throughput of the UE is improved.
