Taking the communication system 100 shown in FIG. 1 as an example, the communication device can include a network device 110 and a terminal device 120 having a communication function, and the network device 110 and the terminal device 120 include, although not described here, It can be the specific equipment mentioned above. The communication equipment may further include other devices within the communication system 100, such as other network entities such as a network controller, a mobile management entity, etc., and embodiments herein are not limited thereto.

It should be understood that the terminal equipment and network equipment in the embodiments of the present application support different UCIs being transmitted simultaneously on the same uplink channel.

Before explaining the UCI transmission method provided by the embodiment of the present application, the following points will be explained first.

First, in the examples shown below, terms such as first UCI, first preset threshold, etc. and English acronyms are illustrative examples for ease of explanation and do not limit the present application in any way. It's not something you do. This application does not exclude the possibility of defining other terms capable of achieving the same or similar functionality in existing or future contracts.

Second, in the embodiments shown below, the first, second, and various numerical numbers are merely distinctions for convenience of explanation, e.g., to distinguish different UCIs, etc., and are within the scope of the embodiments of the present application. It is not limited to.

Thirdly, "at least one" means one or more, and "plurality" means two or more. "and/or" describes a related relationship of related objects and indicates that three relationships may exist; for example, A and/or B is a situation in which A exists alone; Three situations may be shown: a situation in which B exists simultaneously, and a situation in which B exists alone, and A and B may be singular or plural. The character "/" always indicates that the related objects before and after are in the relationship of "or". The phrase "at least one of" or similar expressions refers to any combination of these terms, including any combination of single or multiple terms. For example, at least one of a, b, and c is a, or b, or c, or a and b, or a and c, or b and c, or a, b, and c. a, b, and c may be single or plural.

For ease of understanding, concepts related to embodiments of the present application will be briefly described.

In a 5G NR system, one user equipment (UE) supports, for example, enhanced mobile broadband (eMBB) services and ultra-reliable and low latency communication. on, URLLC) services, etc. , multiple different service types can be supported, and different service types have different requirements for reliability and transmission delay.

Illustratively, since URLLC service processes can occur sporadically and irregularly, different system resources are reserved independently for different services, but if the resources reserved for URLLC are not used. This results in excessive overhead and waste of system resources. To improve system resource utilization, the UE may support multiplexing transmissions of different services on the same resource.

In one possible implementation, the UE reaches the URLLC service after the eMBB service is scheduled to be transmitted on resource 1, and in order to meet the delay requirements of the URLLC service, the UE uses the eMBB for URLLC transmission. It may occupy all or part of the resources (including time domain resources and/or frequency domain resources) of resource 1 allocated to the service.

In another possible implementation, to meet the delay requirements of URLLC services, time-domain resources (sets of symbols) on the same carrier that are scheduled for eMBB services, regardless of whether the frequency-domain resources overlap ) may be scheduled for transmission by URLLC. Since two uplink channels cannot be transmitted simultaneously on the same carrier at the same time, the eMBB service will be interrupted or canceled by the URLLC service.

Therefore, different physical layer priorities can be defined for different services to better support the transmission of different services with different requirements and avoid mutual influence between services. When uplink channels with different physical layer priorities collide, the UCI carried on the lower priority uplink channel is discarded and only the UCI carried on the higher priority uplink channel is transmitted. Can be done.

It should be understood that the above uplink channel may be a PUCCH or a physical uplink shared channel (PUSCH).

The above-mentioned collision of uplink channels with different physical layer priorities occurs when multiple uplink channels transmitted on the same carrier overlap in the time domain, or when multiple uplink channels transmitted on the same carrier overlap in the time domain. It can be understood that the transmission time interval of is smaller than a preset threshold (used for high frequency scenes).

Illustratively, the UCI includes hybrid automatic repeat request-acknowledgment (HARQ-ACK), channel state information (CSI), scheduling request (scheduled ing request, SR) The UCI is transmitted on PUCCH or PUSCH.

Here, HARQ -ACK is a general term for confirmation response (ACKNOWLEDGMENT, ACK) and non -confirmation (NACK), and the Physical Downlink Shared Channelle. , PDSCH), or half -hold scheduling (semi-persistent scheduling, SPS) A PDCCH that instructs the base station to release the PDSCH or the SPS PDSCH by providing feedback on either the physical downlink control channel (PDCCH) indicating the release of the PDSCH or the SPS PDSCH. Notify whether or not it was received correctly.

CSI is used to feed back the downlink channel quality to help the base station perform better downlink scheduling, e.g., a modulation and coding scheme , based on the CSI. MCS), appropriate resource block (RB) configuration, etc.

When there is an uplink service that needs to be transmitted by a terminal device, the SR is used to request a base station for transmission resources for the PUSCH on which the uplink service is carried.

The physical layer priority of PUCCH and PUSCH can be obtained by default, dynamic indication of downlink control information (DCI), or semi-static configuration of radio resource control (RRC). .

Illustratively, when the PUCCH carries an SR, its physical layer priority is determined by the priority corresponding to the loaded SR, and the priority corresponding to each SR is set by upper layer signaling.

For example, when PUCCH carries HARQ-ACK of SPS PDSCH or carries HARQ-ACK of PDCCH that instructs release of SPS resources, the physical layer priority is set to SPS by upper layer signaling. The determination is made based on the HARQ-ACK codebook number configured for the PDSCH. In this specification, the HARQ-ACK codebook corresponding to number 0 is given a low priority, and the HARQ-ACK codebook corresponding to number 1 is given a high priority.

Illustratively, when PUCCH carries CSI, its physical layer priority is set to low priority by default. Herein, CSI may be periodic CSI or semi-persistent channel state information (semi-persistent CSI, SP-CSI).

For example, if the DCI used for the PDCCH includes a priority indication area, when the PDCCH schedules one PDSCH, the priority indication area indicates the priority of the PUCCH on which the HARQ-ACK of this PDSCH is carried. or when the PDCCH schedules one PUSCH, the priority indication area can indicate the priority of the scheduled PUSCH, where the PUSCH is a transport block , TB) and/or a PUSCH carrying aperiodic channel state information (periodic CSI, A-CSI). For a PUSCH carrying SP-CSI, its priority may be obtained by activating a priority indication area in the DCI of the PUSCH carrying SP-CSI.

For example, if the DCI used for the PDCCH does not include a priority indication area, or if the priority is not set by upper layer signaling, the priority is set to be low by default.

In the 5G NR system, five PUCCH formats (hereinafter referred to as PFs) are defined: NR PUCCH formats 0, 1, 2, 3, and 4. Among them, PFs 0 and 1 are for UCI transmission of 1 to 2 bits. PF 2, 3, and 4 can carry UCI transmissions larger than 2 bits, PF 0 and 2 are short PUCCHs and occupy 1 to 2 symbol transmissions, PF 1 , 3, and 4 correspond to long PUCCHs, and can occupy 4 to 14 symbol transmissions.

Exemplarily, SR may be transmitted using PF 0 or 1, and HARQ-ACK may be transmitted using any of 5 PFs.

The 5G NR system does not support the existence of multiple PUCCHs that are transmitted in parallel at the same time on one carrier that transmits PUCCHs. When there are multiple UCIs with different physical layer priorities that are multiplexed on the same uplink channel, resource collisions may occur. For example, on the same carrier, uplink channels with different priorities may be occupied. Only UCIs with high physical layer priority in the colliding channel are , and discard UCIs of lower physical layer priority, thereby affecting lower priority services.

Illustratively, if the lower priority HARQ-ACK is discarded, the lower priority downlink transmission cannot get immediate feedback, so unnecessary retransmissions will occur, and the lower priority When the SR is discarded, the base station cannot obtain scheduling requests for lower priority services, so the base station cannot immediately send an uplink grant (UL grant) to the terminal equipment. Therefore, uplink services cannot be transmitted immediately.

Furthermore, for terminal devices in which both unicast and multicast (or broadcast) services exist at the same time, the HARQ-ACKs of both the corresponding unicast and multicast (or broadcast) services may also conflict.

In view of the above circumstances, the embodiments of the present application provide a UCI transmission method and apparatus, which can support multiplex transmission of UCIs with different priorities on the same carrier on the same channel, To avoid affecting lower priority services due to discarding UCI carried on lower priority uplink channels.

In one possible implementation, UCI multiplexing transmission on multiple PUCCHs can be performed depending on different UCI types and PFs used for the UCI, if certain time conditions are met. In this multiplex transmission method, different NR PFs are set for HARQ-ACK and SR, and specifically include the following.

(1) PUCCH on which SR is carried overlaps with PUCCH on which HARQ-ACK is carried, and PUCCH on which HARQ-ACK is carried is PF 0 (PUCCH on which SR is carried uses PF 0. (or PF 1 may be used), SR and HARQ-ACK are multiplexed on the PUCCH resource of HARQ-ACK, that is, on the PUCCH resource of HARQ-ACK, positive A cyclic shift (CS) corresponding to the HARQ-ACK corresponding to the presence of either SR or negative SR is selected to transmit the HARQ-ACK, and either positive SR or negative SR is implicitly detected. to express.

(2) PUCCH carrying SR overlaps with PUCCH carrying HARQ-ACK, and PUCCH carrying SR uses PF 0, and PUCCH carrying HARQ-ACK uses PF 1. If used, the SR is discarded, ie, no multiplex transmission is performed at this time.

(3) PUCCH carrying SR overlaps with PUCCH carrying HARQ-ACK, and PUCCH carrying SR uses PF 1, and PUCCH carrying HARQ-ACK also uses PF 1. When utilized, if a positive SR exists, HARQ-ACK is transmitted on the PUCCH resource of the SR, and the simultaneous presence of SR transmission is confirmed by transmitting HARQ-ACK using the PUCCH resource corresponding to the SR. Implicitly, in the presence of negative SR, HARQ-ACK is transmitted on the HARQ-ACK PUCCH resource.

(4) PUCCH on which SR is carried overlaps with PUCCH on which HARQ-ACK is carried, and PUCCH on which HARQ-ACK is carried is PF 2 or 3 or 4 (PUCCH on which SR is carried is PF PF 0 or PF 1), one PUCCH resource set is determined according to the total number of bits of SR and HARQ-ACK, and corresponds to HARQ-ACK. One PUCCH resource for simultaneously transmitting SR and HARQ-ACK is determined in one determined PUCCH resource set according to the PUCCH resource instruction area in DCI, and among them, SR is K bits and HARQ-ACK is determined. Indicates the SR status of the X SRs that overlap with the ACK (which one is a positive SR or which one is a negative SR), i.e. whether the SR is a positive SR or a negative SR. Regardless, K-bit SR is always transmitted, thereby avoiding changes in the number of UCI bits transmitted on the PUCCH resource of HARQ-ACK due to SR conditions.

The above possible implementations require different multiplexing transmission means to be defined for different numbers of bits of different UCIs and combinations between different PFs, which is complicated to operate.

Also, PUCCH carrying SR (regardless of whether SR is positive SR or negative SR) uses PF 0 or 1, and PUCCH carrying HARQ-ACK uses PF 2 or 3. or 4, SR and HARQ-ACK can be transmitted simultaneously on one PUCCH resource. PUCCH loaded with HARQ-ACK uses PF 0 or 1, that is, when 1 or 2 bits of HARQ-ACK is transmitted, SR and HARQ-ACK are explicitly transmitted simultaneously on one PUCCH resource. Can not do it.

In view of the above circumstances, the UCI transmission method of the embodiment of the present application requires that the PUCCH on which the above HARQ-ACK is carried uses PF 0 or 1 to multiplex transmit a 1 or 2-bit UCI. It is proposed in view of the situation that the number of bits (i.e., the number of bits in the UCI is 1 or 2) can be reduced by adding bits or by adopting a coding mode that supports smaller bits. ), it contributes to the realization of multiplex transmission when there is a collision between multiple types of UCI, which can avoid the effects caused by discarding a certain type of UCI, and is convenient to operate and realize. Cheap.

The UCI transmission method provided by the embodiments of the present application is also applicable to the multiplex transmission scene when there is a collision between multiple types of UCI in the case of a large number of bits (i.e., the number of bits in the UCI is greater than 2). Please understand that it can be done. This application does not limit the number of bits of the UCI.

Hereinafter, the UCI transmission method provided by the present application will be described in detail with reference to FIG. 2.

Exemplarily, FIG. 2 is a flowchart of a UCI transmission method 200 provided by an embodiment of the present application, which can be performed by a terminal device, and the method 200 includes the following steps.

In S201, it is determined whether the number of bits of the UCI sequence exceeds a first preset threshold.

Here, the UCI sequence includes a first UCI and a second UCI, a first uplink channel on which the first UCI is carried, and a second uplink channel on which the second UCI is carried. may overlap in the time domain, or the transmission time interval between the first uplink channel on which the first UCI is carried and the second uplink channel on which the second UCI is carried. is less than the second preset threshold.

In S202, if it is determined that the number of bits of the UCI sequence does not exceed the first preset threshold, the UCI sequence is encoded in the first type of encoding mode, or the UCI sequence is Add stuffing bits or placeholder bits until the total number of bits exceeds the first preset threshold to obtain a stuffed UCI sequence, and convert the stuffed UCI sequence to a second type. Encode in encoding mode.

In S203, the encoded first UCI sequence and the encoded second UCI sequence are transmitted on the same uplink channel.

In the embodiment of the present application, when a collision exists between a first uplink channel carrying a first UCI and a second uplink channel carrying a second UCI, the terminal equipment uses different UCIs with different numbers of bits. can be encoded in a coding mode to achieve the purpose of transmitting multiple different UCIs on the same uplink channel. When transmitting the UCI in encoded mode, the content indicated by the UCI sequence is different when determining whether the number of bits of the UCI sequence exceeds a first preset threshold according to different encoding rules. The first UCI and the second UCI adopt a joint encoding rule, that is, when the information of the first UCI and the second UCI are cascaded and encoded, the number of bits of the UCI sequence is determined in S201 above. When determining whether or not exceeds the first preset threshold, the UCI sequence is a sequence in which the first UCI and the second UCI are cascaded, that is, at this time, the first UCI and a second UCI is a sequence in which the first UCI and the second UCI are cascaded, and the first UCI and the second UCI adopt independent encoding rules, that is, When encoding the first UCI and the second UCI, when determining whether the number of bits of the UCI sequence exceeds the first preset threshold in S201 above, the UCI sequence is For example, when encoding the first UCI, the first UCI is used, and when encoding the second UCI, the second UCI is used. Since the first UCI and the second UCI need to be transmitted simultaneously, the terminal needs to encode the first UCI and the second UCI respectively, which means that both the two UCIs are encoded and this In this case, the fact that the UCI sequence includes the first UCI and the second UCI means processing for each of the first UCI and the second UCI.

Accordingly, according to the different encoding modes of the terminal equipment, the network equipment determines the corresponding decoding mode, decodes the UCI sequence that has undergone processing such as encoding, and decodes the UCI sequence with the first UCI. It is necessary to correctly decode the second UCI.

The first type of coding mode mentioned above is repetition coding and RM coding, among which repetition coding is the coding mode used when 1 or 2 bit HARQ-ACK is transmitted on PUSCH. RM encoding may be RM (24, O1) encoding or RM (32, O2) encoding, where O1 and O2 are UCI sequences input to the encoder and waiting to be encoded. O1 can be set to 1 to 13, and O2 can be set to 1 to 11.

The second type of coding mode mentioned above is RM coding, Polar coding, low density parity check (LDPC) coding, tail biting convolutional coding (TBCC) coding, or This is Turbo encoding.

The first preset threshold mentioned above may be 2 bits (other numbers of bits are not excluded).

The above-mentioned stuffing bits or placeholder bits may be duplicates of UCI bits or bits stuffed to a preset bit state, for example, fixed to "1" or "0", or may be stuffed bits fixed to "1" or "0"; ” and “0”.

It should be understood that the physical layer priorities of the first UCI and the second UCI may be the same or different.

Optionally, the first UCI and the second UCI are either a UCI corresponding to a unicast service or a UCI corresponding to a multicast service, for example, the first UCI corresponds to a unicast service. UCI, the second UCI is a UCI corresponding to a multicast service, or the first UCI is a UCI corresponding to a multicast service, and the second UCI is a UCI corresponding to a unicast service. It is.

The method 200 may be performed in the same carrier group, i.e., the first uplink channel carrying the first UCI and the second uplink channel carrying the second UCI are the same. , that is, the above collisions are collisions occurring in the same carrier group, and collisions between uplink channels in different carriers may not be performed according to the method 200.

Method 200 may be performed when enabling or configuring the first UCI and the second UCI to be multiplexed on the same uplink channel.

The existence of a collision between the first uplink channel and the second uplink channel means that the first uplink channel and the second uplink channel may overlap in the time domain, or the first uplink channel and the second uplink channel may overlap in the time domain. It may be understood that the transmission time interval between the one uplink channel and the second uplink channel is less than the first preset threshold.

When the first uplink channel and the second uplink channel do not overlap in the time domain, the end symbol of the first uplink channel (assuming that the first uplink channel is a channel with an early start time) and the start symbol of the second uplink channel (assuming that the second uplink channel is a channel after the first uplink channel) is less than the first preset threshold; These two channels do not overlap, but since they cannot be transmitted continuously (for example, when a high frequency device needs to be adjusted during high frequency transmission), the first UCI carried on these two channels It should be appreciated that the second UCI needs to be multiplexed on the same uplink channel.

In the embodiment of the present application, for the first UCI and the second UCI, there is a processing mode in which the first UCI and the second UCI are jointly processed, and a processing mode in which the first UCI and the second UCI are processed individually. There may be two processing modes; Next, first, different encoding modes of UCI with different number of bits in case of joint processing mode will be explained in detail.

In one alternative embodiment, the first UCI and the second UCI are in a joint encoding mode (i.e., a cascade connection of the first UCI and the second UCI in a first type of encoding mode). If the first UCI and the second UCI are encoded simultaneously), the terminal equipment cascades the first UCI and the second UCI, When a first cascaded UCI sequence is obtained and it is determined that the total number of bits of the first cascaded UCI sequence does not exceed the first preset threshold, the first cascaded UCI sequence is acquired. encode a UCI sequence in the first type of encoding mode, or add stuffing bits or placeholder bits to the first cascaded UCI sequence in the first cascaded UCI sequence; obtain the stuffed first cascaded UCI sequence by adding the stuffed first cascaded UCI sequence until the total number of bits of the sequence exceeds the first preset threshold; The encoded UCI sequence is encoded in the second type of encoding mode.

As an alternative embodiment, the first UCI is A _1- bit HARQ-ACK, and the second UCI is A _2- bit HARQ-ACK, where A ₁ and A ₂ are equal? are not equal and A ₁ +A ₂ does not exceed the first preset threshold, or the first UCI is A _3- bit HARQ-ACK and the second UCI is SR. Yes, and _A3 does not exceed the first preset threshold.

Hereinafter, _the first UCI shown in _FIG . , LP AN), A ₁ and A ₂ are equal or unequal, A ₁ +A ₂ does not exceed the first preset threshold, and the uplink channel is PUCCH. Now, different encoding modes of UCI with different number of bits in case of joint processing mode will be explained in detail. Among them, there is a collision between the PUCCH on which the HP AN is carried and the PUCCH on which the LP AN is carried.

In FIG. 3, when one HP DCI schedules one PDSCH, the priority indication area in the HP DCI indicates that the priority of the PUCCH carrying the HARQ-ACK of the PDSCH concerned is designated as a high priority. Therefore, one high priority HARQ-ACK, ie, HP AN, can be determined. Similarly, the priority indication area in the LP DCI can indicate the priority of the PUCCH carrying the HARQ-ACK of the PDSCH as a low priority. AN can be determined. The following description of FIGS. 4-6 is similar to that described herein and will not be repeated.

The terminal equipment can support multiple transmission (i.e., simultaneous transmission) of HARQ-ACKs with different priorities on the same PUCCH, in which the first UCI and the second UCI are in the same carrier group. For example, when a secondary carrier component (SCC) for PUCCH transmission is configured, the primary and secondary PUCCH groups are each one carrier group. When a secondary cell group (SCG) is configured, the master cell group (MCG) and the SCG are each one carrier group.

Illustratively, when the value of A ₁ is 1, the value of A ₂ is 1, and the second preset threshold is 2 bits, the 1-bit HP AN and the 1-bit LP AN are cascaded; A first cascaded UCI sequence of 2 bits is obtained, and since the number of bits of the first cascaded UCI sequence does not exceed the first preset threshold, it is multiplexed in two encoding modes: I can think of situations where this would happen.

(1) The terminal equipment encodes the 2-bit first cascaded UCI sequence using repetition encoding or RM encoding and then undergoes different processing, such as scrambling, modulation, mapping, etc. After that, the first cascaded UCI sequence processed using the determined PUCCH resource is transmitted.

Exemplarily, the terminal equipment determines one PUCCH resource set according to the number of bits of the first cascaded UCI sequence, thereby determining the corresponding PUCCH resource set based on the PUCCH resource indication area in the DCI corresponding to the AN. One PUCCH resource for multiple transmission can be determined in a PUCCH resource set.

It should be understood that the steps for the terminal device to determine the PUCCH, which will be described later, are the same as those described here, and will not be described repeatedly.

(2) The terminal equipment adds one stuffing bit or placeholder bit at the end of the 2-bit first cascaded UCI sequence or at any other position to create the 3-bit stuffed first UCI sequence. The 3-bit stuffed first cascaded UCI sequence is obtained by RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding. This is a scene in which the processed UCI cascaded sequence is transmitted using the determined PUCCH resource after being encoded using the PUCCH resource and subjected to different processing such as scrambling, modulation, and mapping.

Exemplarily, the terminal equipment determines one PUCCH resource set according to the number of bits of the stuffed first cascaded UCI sequence, thereby specifying the PUCCH resource set in the DCI corresponding to the AN. Based on the region, one PUCCH resource for multiple transmission in the PUCCH resource set can be determined.

Adding one stuffing bit or placeholder bit means adding one bit “0”, adding one bit “1”, adding one bit of duplicate information of HP AN, or adding one bit of duplicate information of LP AN. This may include adding one bit of duplicate information, or any other type of stuffing bits and placeholder bits may be added, and embodiments of the present application do not limit this here.

Illustratively, the value of A ₁ is 1, the value of A ₂ is 2, and the second preset threshold is 2 bits. A 1-bit HP AN and a 2-bit LP AN can be cascaded to obtain a 3-bit first cascaded UCI sequence, and the number of bits of the first cascaded UCI sequence is the first preset. Since the threshold is exceeded, multiplex transmission may be performed using the following encoding mode.

The terminal equipment encodes the 3-bit AN cascaded sequence using RM encoding, Polar encoding, LDPC encoding, TBCC encoding or Turbo encoding and performs scrambling, modulation, This is a scene in which the processed first cascade-connected UCI sequence is transmitted using the determined PUCCH resource after undergoing different processing such as mapping.

In embodiments of the present application, in the joint processing mode, if the total number of bits of the cascaded sequence of the first UCI and the second UCI exceeds the first preset threshold, then the second type of encoding mode can be encoded directly with

For network equipment, the processing process is similar to the execution steps for the terminal equipment above, illustratively, the network equipment adds stuffing bits or placeholders to the 2-bit first cascaded UCI sequence. Since it can be determined that a new sequence has been obtained by adding one bit, it can be determined that the number of bits of the new sequence input to the encoder is 3, and thereby the determined PUCCH resource receive target encoded information obtained by processing such as encoding, and decode the target encoded information using RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding, Three bits of information are obtained, and the first two bits are extracted as HP AN and LP AN, respectively.

In the scene of multiplex transmission of small bit UCI, the values of A ₁ and A ₂ can be 1 or 2, respectively, and the values of A ₁ and A ₂ can be equal or unequal.

In collaborative processing mode, the first UCI can also be a high priority SR (hereinafter abbreviated as HP SR) or a low priority SR (hereinafter abbreviated as LP SR), and the second UCI is: It can be HP SR or LP SR or other different service types, such as CSI, and the embodiments of the present application do not limit it here.

As an alternative embodiment, when the first UCI is A _3- bit HARQ-ACK and the second UCI is SR, the method specifically includes:
determining that the number of bits in the SR is X bits, cascading the X-bit SR with the first UCI to obtain a third cascaded UCI sequence; Method 1 of encoding a UCI sequence in the second type of encoding mode, or
determining that the number of bits in the SR is X bits, cascading the X-bit SR with the first UCI to obtain a third cascaded UCI sequence; upon determining that the total number of bits of the UCI sequence does not exceed the first preset threshold, encode the third cascaded UCI sequence in the first type of encoding mode; stuffing bits or placeholder bits for the third cascaded UCI sequence until the total number of bits of the third cascaded UCI sequence exceeds the first preset threshold. additionally obtain a stuffed third cascaded UCI sequence, encode the stuffed third cascaded UCI sequence with the second type of encoding mode, and encode the stuffed third cascaded UCI sequence with the second type of encoding mode; A method 2 of encoding the third cascaded UCI sequence in a second type of encoding mode upon determining that the total number of bits of the third cascaded UCI sequence exceeds a preset threshold; It includes two methods:
Here, X=ceil(log2(K+1)), ceil() is for rounding up the decimal point, and K is the number of set SRs , or the condition that an uplink channel may overlap in the time domain with said first uplink channel , or transmission of a second uplink channel carrying SR with said first uplink channel; It is assumed that the number of SRs satisfies the condition that the time interval is smaller than the second preset threshold.

As shown in FIG. 4, when there is one LP SR that overlaps with the A _3- bit HP AN, the terminal device determines that the number of bits X of the SR is 1, and the number of bits of the HP AN is 1. , when the first preset threshold is 2 bits, cascading 1 bit HP AN and 1 bit LP SR to obtain a 2 bit third cascaded UCI sequence, and the third Since the number of bits of the cascade-connected UCI sequence does not exceed the first preset threshold, the following situation can be considered in which multiplex transmission is performed using method 2 above.

(1) The terminal equipment encodes the 2-bit third cascaded UCI sequence using repetition encoding or RM encoding and then undergoes different processing, such as scrambling, modulation, mapping, etc. After that, the third cascaded UCI sequence processed using the determined PUCCH resource is transmitted.

(2) The terminal equipment adds one stuffing bit or placeholder bit at the end of the 2-bit third cascaded UCI sequence or at any other position to generate the 3-bit stuffed third UCI sequence. A cascaded UCI sequence of 3 bits can be obtained using RM encoding, Polar encoding, Low Density Parity Check (LDPC) encoding, Tail Biting Convolution (TBCC) encoding, or Turbo encoding. After encoding the stuffed third cascaded UCI sequence and undergoing different processing, such as scrambling, modulation, mapping, etc., the third cascaded UCI sequence is processed using the determined PUCCH resources. This is a scene in which a UCI sequence is transmitted.

When the terminal device determines that the bit number cascade and obtain a third cascaded UCI sequence of 3 bits, and since the number of bits of the UCI cascaded sequence exceeds the first preset threshold, multiplex it using method 1 above. One possible scenario is transmission.

The terminal equipment encodes the UCI cascaded sequence using RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding, and performs functions such as scrambling, modulation, mapping, etc. After undergoing different processing, the determined PUCCH resources are used to transmit the third cascaded UCI sequence.

It should be understood that the above SR can also be an HP SR, ie, the priority of the SR is the same as the HP AN, and the embodiments of the present application do not limit it here. The number of bits of the SR mentioned above can also be other values such as 2 bits or 3 bits, and when the number of bits of the SR is 2 bits, it can be directly cascaded with a 1 or 2 bit HP AN. , encode the cascaded UCI sequences using RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding, and after undergoing different processing such as scrambling, modulation, mapping, etc. , transmits the processed cascaded UCI sequence using the determined PUCCH resource.

As shown in FIG. 5, when there are multiple LP SRs (for example, LP SR1 and LP SR2) that overlap with the HP AN, the terminal device determines that the number of bits of the LP SR is 2, and Assuming that the number of bits is 1 and the second preset threshold is 2 bits, a 1-bit HP AN is cascaded with a 2-bit LP SR to obtain a 3-bit UCI cascaded sequence; Since the number of bits of the UCI cascaded sequence is greater than the second preset threshold, the UCI cascade of the three bits is performed using RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding. and transmit the processed UCI cascaded sequence using the determined PUCCH resources after undergoing different processing such as scrambling, modulation, mapping, etc.

The joint processing mode of two UCIs with different priorities, the first UCI and the second UCI, has been explained above, but below, the joint processing mode of the terminal equipment when the third UCI exists will be explained in detail. , among them, the third UCI has the same priority as at least one of the first UCI and the second UCI, or has the same priority as the first UCI and the second UCI. Make it different.

As an alternative embodiment, when the first UCI is A _1- bit HARQ-ACK, and the second UCI is A _2- bit HARQ-ACK, the method comprises:
If there is further a third uplink channel loaded with SR that overlaps in the time domain with the first uplink channel and/or the second uplink channel; If the transmission time interval between the uplink channel of No. 3 and the first uplink channel and/or the second uplink channel is smaller than the second preset threshold;

Upon determining that a preset threshold is exceeded, the method further comprises employing one of two methods: encoding the second cascaded UCI sequence in a second type of encoding mode; ,
Here, X=ceil(log2(K+1)), ceil() is for rounding up the decimal point, and K is the number of set SRs , or an uplink channel may overlap in the time domain with said first uplink channel and/or a second uplink channel, or a third uplink channel carrying an SR and said first uplink channel; and/or the second uplink channel is the number of SRs satisfying the condition that the transmission time interval with the uplink channel and/or the second uplink channel is smaller than the second preset threshold.

Hereinafter, the first UCI is A _1- bit HP AN, the second UCI is A _2- bit LP AN, the third UCI is X-bit HP SR, and the uplink channel is PUCCH. Taking an example as an example, the process of three UCI multiplex transmissions in the joint processing mode will be described. Among them, there is a collision between PUCCH on which HP AN is carried and PUCCH on which LP AN is carried, and PUCCH on which HP SR is carried is different from PUCCH on which HP AN and/or LP AN is carried. There is a conflict.

For example, when there is one HP SR shown in FIG. 6 that overlaps with the AN (HP AN and/or LP AN), the terminal equipment determines that the value of X is 1, and the value of A is ₁ . is 1, the value of _A2 is 1, and the first preset threshold is 2 bits, the terminal equipment cascades 1 bit HP AN, 1 bit LP AN and 1 bit HP SR. and a second cascaded UCI sequence of 3 bits is obtained, the number of bits of the second cascaded UCI sequence exceeds the first preset threshold, and the stuffing bits or placeholder bits are added. Since there is no need to do this, there are cases where multiplex transmission is performed using the following encoding modes.

The terminal equipment is in a situation where the second cascaded UCI sequence is encoded using RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding.

For network equipment, the processing process is similar to the steps performed above for the terminal equipment, where the network equipment determines that the number of bits in the second cascaded UCI sequence that the terminal equipment inputs to the encoder is 3. As a result, target encoding information obtained by processing such as encoding with the determined PUCCH resource is received, and RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding is performed. The target encoded information is decoded using the decoding method to obtain 3 bits of information, and 1 bit of HP AN, 1 bit of LP AN, and 1 bit of HP SR are extracted, respectively.

Above, we have explained the process of multiplex transmission of multiple UCIs on the same uplink channel in coding mode in the case of joint processing mode, with reference to a specific example. The process will be explained in detail.

Hereinafter, the first UCI is A _1- bit HP AN, the second UCI is A _2- bit LP AN, and the uplink channel is PUCCH. The process of two UCI multiplex transmissions will be described. Among them, there is a conflict between PUCCH on which HP AN is carried and PUCCH on which LP AN is carried.

As an alternative embodiment, the terminal device determines whether the number of bits of the first UCI and the number of bits of the second UCI each exceed the first preset threshold, and If it is determined that the number of bits of the first UCI does not exceed the first preset threshold, the first UCI is encoded in the first type of encoding mode, or stuffing bits are added to the first UCI. or add placeholder bits until the number of bits in the first UCI exceeds a first preset threshold to obtain a stuffed first UCI sequence, and obtain a stuffed first UCI sequence; encoding the UCI sequence in a second type of encoding mode and/or determining that the number of bits of the second UCI does not exceed the first preset threshold; encoding mode or adding stuffing bits or placeholder bits to the second UCI until the number of bits in the second UCI exceeds the first preset threshold. to obtain a stuffed second UCI sequence, and encode the stuffed second UCI sequence in a second type of encoding mode.

In the case of the independent processing mode, the terminal device encodes the UCI whose number of bits does not exceed the first preset threshold among the first UCI and the second UCI in the first type of encoding mode. or the terminal equipment adds stuffing bits or placeholder bits to the UCI that does not exceed the first preset threshold, and the number of bits of the UCI sequence to which the bits are added exceeds the first preset threshold. and the UCI sequence in which the stuffing bits have been performed can be encoded in a second type of encoding mode.

As an alternative embodiment, the first UCI is A _4- bit HARQ-ACK, and the second UCI is A ₅ -bit HARQ-ACK, where A ₄ and A ₅ are equal? unequal and at least one of A ₄ and A ₅ does not exceed the first preset threshold, or the first UCI is A _6- bit HARQ-ACK and the second UCI is SR, where at least one of the bits of SR and _A6 does not exceed the first preset threshold, and the number of bits of SR is X=ceil(log2(K+1)) and ceil( ) is for rounding up the decimal point, and K is the number of configured SRs, or if the second uplink channel carrying the SR is the same as the first uplink channel in the time domain. the condition that there is overlap or that the transmission time interval between the second uplink channel carrying the SR and the first uplink channel is less than the second preset threshold is met; is the number of SRs.

Hereinafter, the first UCI is A _4- bit HP AN, the second UCI is A _5- bit LP AN, and the uplink channel is PUCCH. The process of two UCI multiplex transmissions will be explained. Among them, there is a conflict between PUCCH on which HP AN is carried and PUCCH on which LP AN is carried.

For example, when the value of _A4 is 1, the value of _A5 is 1, and the first preset threshold is 2 bits, the value of _A4 and the value of _A5 are both the first preset Since the threshold value is not exceeded, a situation may be considered in which multiplex transmission is performed in the following two encoding modes.

(1) The terminal device independently encodes the 1-bit HP AN and 1-bit LP AN using repetition encoding or RM encoding, and performs scrambling, modulation, mapping, etc. This is a scene in which the processed HP AN and LP AN are transmitted using the determined PUCCH resources after undergoing different processing.

For example, one PUCCH resource set is determined according to the total number of bits 2 of 1-bit HP AN and 1-bit LP AN, and the corresponding PUCCH resource set is determined based on the PUCCH resource indication area in the DCI corresponding to the AN. One PUCCH resource for multiple transmission can be determined in the resource set.

(2) The terminal equipment adds 2 bits each of stuffing bits or placeholder bits at the end of the 1-bit HP AN and 1-bit LP AN or at any other arbitrary position, and adds a new 3-bit HP sequence and 3 A new LP sequence of bits is obtained and the 3-bit After encoding a new HP sequence and a new LP sequence of 3 bits, and passing through different processing such as scrambling, modulation, mapping, etc., the new HP sequence and the new HP sequence processed using the determined PUCCH resources are encoded. This is a scene in which a new LP sequence is transmitted.

For example, one PUCCH resource set is determined according to the total number of bits 6 of the 3-bit new HP sequence and the 3-bit new LP sequence, and the PUCCH resource instruction area in the DCI corresponding to the AN is determined. Based on the PUCCH resource set, one PUCCH resource for multiplex transmission can be determined based on the PUCCH resource set.

Similarly, regarding network equipment, terminal equipment adds 2 stuffing bits or placeholder bits to 1-bit HP AN, and terminal equipment adds stuffing bits or placeholder bits to 1-bit LP AN. Since it can be determined that 2 bits have been added, the network device can determine that the new HP sequence and new LP sequence that the terminal device input to the encoder are both 3 bits, and thereby the 6-bit A new HP sequence and a new LP sequence that have been processed, such as encoding, are generated using the PUCCH resource for which information (the sum of the bit numbers of a 3-bit new HP sequence and a 3-bit new LP sequence) has been determined. and extracts information corresponding to HP AN and information corresponding to LP AN from the received information, and performs RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding. Using each, independent decoding is performed on the information corresponding to HP AN and the information corresponding to LP AN, and 3 bits of HP information and 3 bits of LP information are obtained. AN and LP Can be extracted as AN.

Illustratively, when the value of _A4 is 3, the value of _A5 is 2, and the first preset threshold is 2 bits, then the value of _A4 exceeds the first preset threshold; Since the value of ₅ does not exceed the first preset threshold, a situation where multiplex transmission is performed in the following encoding mode is possible.

The terminal equipment uses RM encoding, Polar encoding, low-density parity check (LDPC) encoding, tail-biting convolution (TBCC) encoding, or Turbo encoding to generate independent codes for the 3-bit HP AN. , add one stuffing bit or placeholder bit at the end of the 2-bit LP AN or any other position to obtain a 3-bit stuffed LP AN sequence, and perform RM encoding, Polar encoding. , perform independent encoding on the 3-bit stuffed LP AN sequence using LDPC encoding, TBCC encoding, or Turbo encoding and perform different processing, such as scrambling, modulation, mapping, etc. , the processed HP AN and LP AN sequences are transmitted using the determined PUCCH resources.

In embodiments of the present application, in the case of an independent encoding mode, a UCI sequence exceeding a first preset threshold may be encoded in a second type of encoding mode, and a UCI sequence exceeding a first preset threshold may be encoded in a second type of encoding mode. The stuffing bits may be added to the UCI sequences that do not have the stuffing bits until the stuffing bits exceed the first preset threshold, or may be encoded directly in the first type of encoding mode.

Illustratively, when the value of _A4 is 3, the value of _A5 is 1, and the first preset threshold is 2 bits, the value of _A4 exceeds the first preset threshold; Since the value of ₅ does not exceed the first preset threshold, a situation where multiplex transmission is performed in the following two encoding modes is possible.

(1) A terminal device performs independent encoding on a 1-bit LP AN using iterative encoding or RM encoding, and performs RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding. perform independent encoding on the 3-bit HP AN using This is a scene in which the processed HP AN and LP AN are transmitted using the PUCCH resource.

For example, one PUCCH resource set is determined according to the total number of bits 4 of the 3-bit HP AN and 1-bit LP AN, and the corresponding PUCCH resource set is determined based on the PUCCH resource indication area in the DCI corresponding to the AN. One PUCCH resource for multiple transmission can be determined in the resource set.

(2) The terminal equipment performs independent encoding on the 3-bit HP AN using RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding, and performs independent encoding on the 1-bit LP AN. Adding two stuffing bits or placeholder bits at the end or any other position results in a new 3-bit LP sequence, which can be RM encoded, Polar encoded, LDPC encoded, TBCC encoded, or Turbo encoded. The encoded HP sequence and the new LP sequence are subjected to different encoding, e.g. scrambling, modulation, mapping, etc. This is a scene where processing is performed and a new LP sequence is transmitted to the processed HP AN using the determined PUCCH resource.

Exemplarily, one PUCCH resource set is determined according to the total number of bits 6 of the 3-bit HP AN and 3-bit new LP sequence, and based on the PUCCH resource indication area in the DCI corresponding to the AN, One PUCCH resource for multiplex transmission can be determined in the PUCCH resource set.

In the above process of two UCI multiplex transmission in independent processing mode, the first UCI can be HP SR or LP SR, and the second UCI can be HP SR or LP SR, or other different service types, It should be understood that it could also be CSI, for example. The embodiments herein do not limit it here.

The embodiments of the present application do not limit the values of A ₁ and A ₂ . For example, the values of A ₁ and A ₂ may both be 2, or the value of A ₁ may be 2. The value may be 2 and the value of A ₂ may be 1, or the value of A ₁ may be 1 and the value of A ₂ may be 2, and the processing process Same as the above description except that it is necessary to add 1 stuffing bit or placeholder bit to the bit AN, and to add 2 stuffing bits or placeholder bits to 1 bit AN. It is something.

It should be understood that the value of the first preset threshold in embodiments of the present application may be any other value. The embodiments herein do not limit it here.

For network equipment, the processing process is similar to the execution steps for the terminal equipment above, where the network equipment adds one stuffing bit or placeholder bit to the 2-bit HP cascaded sequence; Since it can be determined that 2 bits of stuffing bits or placeholder bits have been added to a 1-bit LP AN, the network device can determine the number of bits of the new HP sequence and new LP sequence input by the terminal device to the encoder. is determined to be 3, and receives a new HP sequence and a new LP sequence obtained by processing such as encoding using the determined PUCCH resource, and includes the new HP sequence in the received information. The information corresponding to the sequence and the information corresponding to the new LP sequence are extracted and decoded respectively, and 3-bit HP information and 3-bit LP information are obtained. The bits can be extracted as HP AN and HP SR, and the first bit of the 3-bit LP information can be extracted as LP AN.

Illustratively, assume that the first UCI is an A _6- bit HP AN and the second UCI is one LP SR, as shown in FIG. When _the terminal device determines that the number of bits X of the LP SR is 1, the value of _A6 is 1, and the first preset threshold is 2 bits, the value of A6 is the first preset threshold. and the value of

The terminal equipment can add 2 bits of stuffing or placeholder bits at the end of the 1-bit HP AN or any other position to obtain a new 3-bit HP AN sequence, and performs RM encoding, Polar encoding. , independently encode the 3-bit new HP AN sequence using LDPC encoding, TBCC encoding, or Turbo encoding, and add stuffing bits at the end of the 1-bit LP SR or at any other position. Or you can add 2 placeholder bits to get a new LP SR sequence of 3 bits, and use RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding of the 3 bits. Performing independent encoding on the new LP SR sequence, and then performing different processing, such as scrambling, modulation, and mapping, on the encoded new HP AN sequence and the new LP SR sequence, This is a scene in which a new HP AN sequence and a new LP SR sequence processed using the determined PUCCH resource are transmitted.

For example, as shown in FIG. 5, if there are two LP SRs that overlap with the HP AN, the terminal equipment determines that the number of bits X of the LP SR is 2, and the value of _A6 is 1. , and the first preset threshold is 2 bits, the value of _A6 does not exceed the first preset threshold, and the value of X does not exceed the first preset threshold, so the following encoding A scenario can be considered where multiplex transmission is performed in different modes.

The terminal equipment can add 2 bits of stuffing or placeholder bits at the end of the 1-bit HP AN or any other position to obtain a new 3-bit HP AN sequence, and performs RM encoding, Polar encoding. , perform independent encoding on the new 3-bit HP AN sequence using LDPC encoding, TBCC encoding, or Turbo encoding, and add stuffing bits at the end of the 2-bit LP SR or at any other position. Or you can add one placeholder bit to get a new LP SR sequence of 3 bits, and use RM encoding, Polar encoding, LDPC encoding, TBCC encoding, or Turbo encoding of the 3 bits. Performing independent encoding on the new LP SR sequence, and then performing different processing, such as scrambling, modulation, and mapping, on the encoded new HP AN sequence and the new LP SR sequence, This is a scene in which a new HP AN sequence and a new LP SR sequence processed using the determined PUCCH resource are transmitted.

For example, when the number of bits of HP AN is 1 or 2 and the number of bits of LP SR is more than 2 bits (for example, there are two or more LP SRs that overlap with HP AN), then It is necessary to encode in the second type of encoding mode after adding 1 or 2 bits to the AN, and the LP SR with more than 2 bits must be encoded directly in the second type of encoding mode. can be converted into

As an alternative embodiment, when the first UCI is A _1- bit HARQ-ACK and the second UCI is A _2- bit HARQ-ACK, the first uplink channel and/or the If there is further a third uplink channel loaded with SR that overlaps in the time domain with the second uplink channel, or the third uplink channel loaded with SR and the first uplink If the transmission time interval with the channel and/or the second uplink channel is less than a second preset threshold, the method:

In the embodiment of the present application, the first target UCI is a UCI having the same priority as the X-bit SR.

Hereinafter, the first UCI shown in FIG. 6 is A _1- bit HP AN, the second UCI is A _2- bit LP AN, and the third UCI is X-bit HP SR, and Taking as an example that the link channel is PUCCH, the process of multiplexing three UCIs in independent processing mode will be described. Among them, there is a collision between PUCCH on which HP AN is carried and PUCCH on which LP AN is carried, and there is a collision between PUCCH on which HP SR is carried and PUCCH on which HP AN and/or LP AN is carried. There is. Here, in Figure 6 (a, b, and c), the starting positions between HP AN, LP AN, and HP SR may be changed or may not be aligned, but they are all different from each other in this scene. belong to

Exemplarily, when the terminal device determines that the value of X is 1, the value of A ₁ is 1, the value of A ₂ is 1, and the first preset threshold is 2 bits, the target UCI is an HP AN with the same physical layer priority as the HP SR. Since the total number of bits of the cascaded sequence of HP AN and HP SR does not exceed the first preset threshold, and the number of bits of LP AN does not exceed the first preset threshold, the following two encodings A scenario where multiplex transmission is performed in different modes can be considered.

(1) The terminal equipment can cascade 1-bit HP AN and 1-bit HP SR of the same priority to obtain a 2-bit HP cascaded sequence, and use repetition encoding or RM encoding. Then, independent encoding is performed on the HP cascade-connected sequence and the LP AN, and after passing through different processing such as scrambling, modulation, and mapping, the sequence is processed using the determined PUCCH resource. This is a scene in which an HP cascade-connected sequence and an LP AN are transmitted.

For example, one PUCCH resource for multiplex transmission can be determined according to the total number of bits, 6, of a 3-bit new HP sequence and a 3-bit new LP sequence.

Exemplarily, when the terminal device determines that the value of X is 1, the value of A ₁ is 2, the value of A ₂ is 1, and the first preset threshold is 2 bits, the HP AN Since the total number of bits of the cascaded sequences of and HP SR exceeds the first preset threshold, and the number of bits of LP AN does not exceed the first preset threshold, multiplex transmission with the following encoding mode I can think of a situation where this happens.
