Description

Method for transmitting feedback information, terminal equipment and network equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, a terminal device, and a network device for transmitting feedback information.

Background

With the development of wireless communication technology, future communication systems need to adapt to more diversified scenes and service requirements, and a New Radio (NR) system introduces Physical Uplink Control Channels (PUCCHs) of different lengths in order to meet different service requirements and different application scenarios, and further divides a PUCCH carrying UCI with Payload less than or equal to 2bits and a PUCCH carrying UCI with Payload greater than 2bits according to the size of a Payload (Payload) of Uplink Control Information (UCI) carried by the PUCCH. The PUCCH with Payload less than or equal to 2bits for the loaded UCI represents transmitted information by using different sequences. For example, to transmit 1-bit feedback information, two different sequences are used, sequence 1 representing 0 and sequence 2 representing 1, and similarly, to transmit 2-bit feedback information, four different sequences are required. The different sequences may be different Base sequences (Base sequences) or sequences obtained by subjecting the same Base Sequence to different Cyclic Shifts (CS).

The sequence of the current feedback information is a computer search sequence (CGS) of length 12, and the number of available cyclic shifts per base sequence is 12. In this case, multiple terminal equipments (UEs) are allowed to multiplex the same Physical Resource Block (PRB), and in order to randomize interference between multiple users in a cell, a Randomization (Randomization) or Hopping (Hopping) manner may be used to determine cyclic shifts of a feedback information sequence among different slots (slots) or symbols (symbols).

However, in some scenarios (e.g., a Licensed Assisted Access (LAA) scenario), the UE needs to determine that the channel is idle before sending the feedback information, and if it is detected that the channel is occupied, the UE needs to listen again until the channel is idle before sending the feedback information. In this case, if the UE determines the number of shift bits of the cyclic shift in the foregoing randomisation or Hopping manner, even if the UE is ready to send a feedback information sequence in a Slot or Symbol, the UE cannot send a prepared feedback information sequence on the Slot or Symbol because the UE detects that a channel in the Slot or Symbol is occupied, and when the UE detects that a channel is idle in a subsequent Slot or Symbol, the UE needs to prepare the feedback information sequence to be sent again because the cyclic shift that needs to be used is different from the cyclic shift that was used by the previously prepared feedback information sequence, which increases the implementation complexity of the UE.

In addition, when the UE transmits the PUCCH using 2 Orthogonal Frequency Division Multiplexing (Orthogonal Frequency Division Multiplexing) symbols (symbols), if the Subcarrier spacing (SCS) is relatively large, the duration of each OFDM Symbol is short, and if the number of shift bits of the cyclic shift is determined by using the randomisation or Hopping method of the cyclic shift between symbols, the sequence transmitted by the UE on each Symbol is different, which also increases the processing complexity of the UE.

A Terminal device (UE), which may also be referred to as a Mobile Terminal (Mobile Terminal), a Mobile User Equipment (UE), or the like, may communicate with one or more core networks via a Radio Access Network (RAN, for example), and the User device may be a Mobile Terminal, such as a Mobile phone (or a "cellular" phone) and a computer having a Mobile Terminal, such as a portable, pocket, handheld, computer-included, or vehicle-mounted Mobile device, which exchange language and/or data with the Radio Access Network.

The Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, and a 5G Base Station (gNB), but the present invention is not limited thereto, and for convenience of description, the following embodiments take the gNB as an example for description.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 illustrates a method of transmitting feedback information according to one embodiment of the present application. The method shown in fig. 1 may be performed by a terminal device. As shown in fig. 1, the method 100 includes:

and S110, determining the target shift digit of the cyclic shift according to the target determination mode in the multiple determination modes.

In S110, the multiple determination manners include: determining the target shift digit number by randomizing (Randomization) shift digits between different time units, determining the target shift digit number by Hopping (Hopping) shift digits between different time units, and determining the target shift digit number according to a preset corresponding relationship between feedback information and the shift digits. It should be understood that the embodiments of the present invention are not limited to the three methods for determining the number of shift bits described above, and all methods that can be used for determining the number of shift bits may be included in the plurality of determination manners.

Optionally, in some embodiments, the time unit is a Slot (Slot) or a Symbol (Symbol).

Optionally, in some embodiments, the terminal device receives indication information sent by the network device, where the indication information is used to indicate the target determination manner; and the terminal equipment determines a target determining mode according to the indication information.

Specifically, in some embodiments, the terminal device receives a higher layer signaling sent by the network device, where the higher layer signaling includes the indication information. Optionally, the higher layer signaling is Radio Resource Control (RRC) signaling.

It can be understood that the indication information may indicate the target determination manner by a display indication manner, or may indicate the target determination manner by an implicit indication manner. For example, the display indication may be indication information directly indicating a target determination mode, the implicit indication may be a function that the indication information directly indicates whether the terminal device is turned on (Enable) or turned off (Disable) to determine a target shift bit number by using a shift bit number between different time units of ranging or hosting, and if the indication information indicates that the terminal device is turned on (Enable) or turned off (hosting to determine a target shift bit number by using a shift bit number between different time units of ranging or hosting, the terminal device determines the target determination mode to determine a target shift bit number by using a shift bit number between different time units of ranging or hosting to randomize the target shift bit number, interference between multiple terminal devices may be randomized, and reception performance of a Physical Uplink Control Channel (PUCCH) may be improved; otherwise, the terminal equipment determines the target determination mode to determine the target shift digit according to the preset corresponding relation between the feedback information and the shift digit, so that the processing complexity of the terminal equipment can be reduced. It should be noted that the preset correspondence between the feedback information and the shift bit number does not change with the change of the Slot or Symbol, that is, the preset correspondence between the feedback information and the shift bit number corresponding to different slots or symbols is the same.

Optionally, as an example, the target determining manner is to determine the target shift bit number by using a shift bit number between different time units, and the feedback information is Acknowledgement (ACK) information or Negative Acknowledgement (NACK) information, and the ACK information or NACK information is 1bit information. The terminal device may determine the target shift bit number using method a and/or method b described below.

The method a comprises the following steps: assuming that 0 and 1 respectively correspond to fixed shift bits, and meanwhile assuming that the shift bit number corresponding to 0 is 0, the shift bit number corresponding to 1 is 6, the terminal device assumes that ACK information is 1 and NACK information is 0, randomizing 1 or 0 corresponding to ACK information and NACK information, for example, adding a random code and then modulo 2, assuming that the random code is 1, the sum of 1 and 1 is 2, modulo 2 is 0, and the sum of 0 and 1 is 1, the terminal device finally determines that ACK information is 0 and NACK information is 1, and then obtains the shift bit number corresponding to ACK information is 6 and the shift bit number corresponding to NACK information is 0. In this case, if the terminal equipment needs to send ACK information, the base sequence is cyclically shifted by 6 bits to obtain a sequence carrying ACK information, and if the terminal equipment needs to send NACK information, the base sequence is cyclically shifted by 0 bits to obtain a sequence carrying NACK information. Alternatively, different random codes may be determined for different slots or symbols.

The method b: assuming that 0 and 1 correspond to variable shift bit numbers, respectively, the terminal device may randomize shift bit numbers corresponding to 0 and 1 according to an initial shift bit number (an initial cyclic shift bit number) and Slot/Symbol, and then correspond ACK information and NACK information to the corresponding shift bit numbers. Alternatively, the UE may be configured with different number of initial shift bits for different slots or symbols.

Optionally, as another example, the target determining manner is to determine the target shift bit number by using shift bit numbers between different time units of Hopping, in slot n, the shift bit numbers corresponding to the ACK information and the NACK information are 0 and 6, respectively, in slot n +1, the shift bit numbers corresponding to the ACK information and the NACK information are 6 and 1, respectively, in slot n +2, the shift bit numbers corresponding to the ACK information and the NACK information are 0 and 6 …, respectively, and so on.

Optionally, in other embodiments, the terminal device determines the target determination manner according to the number of symbols of the transmission feedback information sequence; or according to the processing capacity of the terminal equipment; or determining the target determination mode according to the wireless access technology adopted when the network equipment is communicated. However, it is understood that the method for determining the target determination manner by the terminal device is not limited to the above three methods.

For example, if the terminal device transmits the feedback information by using 2 Orthogonal Frequency Division Multiplexing (OFDM) symbols, the target determination manner determined by the terminal device is to determine the target shift bit number according to the corresponding relationship between the feedback information and the shift bit number. Therefore, the situation that the terminal equipment has a large Subcarrier Space (SCS) and the shift bit number is determined by adopting the mode of the shift bit number between different time units of random modulation or the shift bit number between different time units of Hopping under the condition that the duration of each OFDM Symbol is short can be avoided, and the processing complexity of the terminal equipment is reduced.

For another example, if the radio Access technology adopted when the terminal device communicates with the network device is a Licensed Assisted Access (LAA) technology, or the terminal device is in an LAA scene, the target determination manner determined by the terminal device is to determine the target shift digit according to the corresponding relationship between the feedback information and the shift digit. Therefore, the problem of increased processing complexity of the terminal equipment caused by the fact that the terminal equipment determines the shift digit by adopting the mode of the shift digit among random time units or the shift digit among Hopping time units can be avoided.

Optionally, as an example, the correspondence between the feedback information and the shift bit number may be specified by a protocol, or may be notified to the terminal device by the network device through signaling. For example, taking the feedback information as ACK information or NACK information, and the ACK information or NACK information is 1-bit information as an example, the corresponding relationship between the feedback information and the shift number may be: the number of shift bits corresponding to ACK information is 0, and the number of shift bits corresponding to NACK is 6.

For another example, if the processing capability of the terminal device is high, the target determining method determined by the terminal device is to determine the target shift digit by using the displacement digits between different time units of randomisation or hosting; and if the processing capacity of the terminal equipment is lower, the target determining mode determined by the terminal equipment is to determine the target shift digit according to the preset corresponding relation between the feedback information and the shift digit.

And S120, circularly shifting the base sequence by the target shift bit number to obtain a feedback information sequence carrying feedback information.

Alternatively, as an example, the motif Sequence is a Computer-Generated Sequence (CGS) of 12 bits in length.

Optionally, in some embodiments, the feedback information is feedback information related to a Hybrid Automatic Repeat Request (HARQ), for example, the feedback information is HARQ-ACK information or HARQ-NACK information.

S130, the feedback information sequence is sent to the network equipment.

Fig. 2 is a method of feeding back information according to an embodiment of the present application. As shown in fig. 2, the method 200 includes:

s210, the base station (gNB) sends RRC signaling to the terminal device.

It should be noted that the RRC signaling is used for the function of determining the shift bit number by using the mode of the shift bit number between different slots or symbols in Randomization or hosting for the Enable or Disable terminal device.

S220, the terminal device determines HARQ feedback information to be transmitted.

It should be noted that, in S220, the terminal device needs to determine whether the HARQ feedback information is HARQ-ACK information or HARQ-NACK information according to the signal receiving condition, and determine the bit number included in the HRAQ feedback information, for example, 1bit or 2 bits.

S230, the terminal device determines a feedback information sequence carrying the HARQ feedback information.

Specifically, in some embodiments, the terminal device determines whether to Enable or Disable according to RRC signaling, and determines the function of the shift bit number in a manner of using the shift bit number between different slots or symbols in rendezvous or hosting. If the function of determining the shift digit by the Enable in the manner of the shift digit among different slots or symbols in Randomization or hosting, the terminal equipment determines the shift digit in the manner of the shift digit among different slots or symbols in Randomization or hosting, and then the determined shift digit is circularly shifted to obtain a feedback information sequence; if the function of determining the shift digit by the mode of the shift digit among different slots or symbols of random or hosting is adopted by the Disable, the terminal equipment determines the shift digit according to the preset corresponding relation between the feedback information and the shift digit, wherein the preset corresponding relation between the feedback information and the shift digit does not change along with the change of the slots or symbols, and then the determined shift digit is circularly shifted by the base sequence to obtain a feedback information sequence.

S240, the terminal equipment sends a feedback information sequence to the base station.

Fig. 3 is a method of transmitting feedback information according to another embodiment of the present application. The method shown in fig. 3 may be performed by a network device. It is to be understood that the interaction between the network device and the terminal device described from the terminal device side is the same as that described in the network device side, and the related description is appropriately omitted to avoid redundancy. As shown in fig. 3, the method 300 includes:

s310, sending indication information to the terminal equipment, wherein the indication information is used for indicating a target determination mode in multiple determination modes;

s320, receiving a feedback information sequence which is sent by the terminal equipment and bears feedback information, wherein the feedback information sequence is obtained by the terminal equipment circularly shifting a base sequence by a target shifting digit, and the target shifting digit is determined by the terminal equipment according to the target determination mode;

According to the method for transmitting the feedback information, the network equipment sends the indication information indicating the target determination mode in the multiple determination modes to the terminal equipment, so that the terminal equipment determines the shift digit of the cyclic shift according to the target determination mode. Therefore, the problem of high complexity of terminal equipment realization caused by the fact that the terminal equipment always determines the shift digit by randomizing or jumping the shift digit among different time units due to the fact that the terminal equipment cannot flexibly select the method for determining the shift digit can be solved.

Optionally, as an embodiment, the sending the indication information to the terminal device includes:
