[0086] Furthermore, in the embodiments of the present application, terminal device 120 may also be a terminal device in an IoT system. IoT is an important component of future information technology development. Its main technical feature is to connect objects to the Internet through communication technology, thereby realizing an intelligent network that interconnects humans and machines and things. In the embodiments of the present application, IoT technology can achieve massive connections, deep coverage, and terminal power saving through, for example, narrowband NB technology.

[0087] Furthermore, in the embodiments of the present application, the terminal device may also be a terminal device that utilizes device-to-device (D2D) communication technology. D2D technology refers to a communication method in which two peer terminal devices communicate directly with each other. In a decentralized network composed of D2D terminal devices, each terminal device node can send and receive signals and has the function of automatic routing (forwarding messages).

[0088] In addition, in an embodiment of the present application, the terminal device may also include sensors such as smart printers, train detectors, and gas stations. Its main functions include collecting data (part of the terminal device), receiving control information and downlink data from the network device, and sending electromagnetic waves to transmit uplink data to the network device.

[0089] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be called a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here; the communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0090] It should be understood that the terminal device and the network device in the embodiments of the present application support simultaneous transmission of different UCIs on the same uplink channel.

[0091] Before introducing the UCI transmission method provided in the embodiment of the present application, the following points are explained.

[0092] First, in the embodiments described below, various terms and abbreviations, such as "first UCI" and "first preset threshold," are provided for ease of description and are not intended to limit this application. This application does not exclude the possibility of defining other terms in existing or future protocols that can achieve the same or similar functions.

[0093] Second, in the embodiments shown below, the first, second, and various numbers are only used for the convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, to distinguish different UCIs, etc.

[0094] Third, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0095] To facilitate understanding, the following briefly introduces the relevant concepts involved in the embodiments of this application.

[0096] In the 5G NR system, a user equipment (UE) can support multiple different service types, such as enhanced mobile broadband (eMBB) and ultra-reliable and low latency communication (URLLC). Different service types have different requirements for reliability and transmission latency.

[0097] For example, URLLC service flows may occur sporadically and irregularly, so different system resources are reserved for different services. However, in some cases, the resources reserved for URLLC are not used, which results in excessive system resource overhead and waste. To improve system resource utilization, the UE can support multiplexing of different services on the same resources.

[0098] In one possible implementation, when the UE is scheduled to transmit an eMBB service on resource 1, and a URLLC service arrives, in order to meet the latency requirements of the URLLC service, all or part of the resources (including time domain resources and / or frequency domain resources) in resource 1 that have been allocated to the eMBB service may be occupied for URLLC transmission.

[0099] In another possible implementation, to meet the latency requirements of URLLC services, all or part of the time domain resources (symbol set) scheduled for eMBB services on the same carrier may be scheduled for URLLC transmission, regardless of whether the frequency domain resources overlap. Since two uplink channels cannot be transmitted simultaneously on the same carrier at the same time, the eMBB service may be interrupted or canceled by the URLLC service.

[0100] Therefore, to better support the transmission of different services with different requirements and avoid mutual interference between services, different physical layer priorities can be defined for different services. When uplink channels with different physical layer priorities conflict, the UCI carried by the lower-priority uplink channel can be discarded, and only the UCI carried by the higher-priority uplink channel can be transmitted.

[0101] It should be understood that the above-mentioned uplink channel may be a PUCCH, or a physical uplink shared channel (PUSCH).

[0102] The above-mentioned conflict between uplink channels with different physical layer priorities can be understood as the overlap of multiple uplink channels transmitted on the same carrier in the time domain; or, the transmission time interval of multiple uplink channels transmitted on the same carrier is less than the preset threshold (for high-frequency scenarios).

[0103] Exemplarily, UCI includes at least one of hybrid automatic repeat request-acknowledgment (HARQ-ACK), channel state information (CSI), and scheduling request (SR), and the UCI is transmitted on PUCCH or PUSCH.

[0104] HARQ-ACK is a general term for positive acknowledgment (ACK) and negative acknowledgment (NACK), and is used to provide feedback on the physical downlink shared channel (PDSCH) or the physical downlink control channel (PDCCH) that indicates the release of semi-persistent scheduling (SPS) resources, informing the base station whether the PDSCH or the PDCCH that indicates the release of SPS PDSCH is correctly received.

[0105] CSI is used to provide feedback on downlink channel quality, thereby helping the base station to better perform downlink scheduling. For example, the modulation and coding scheme (MCS) can be selected and appropriate resource blocks (RBs) can be configured based on the CSI.

[0106] SR is used to request the base station for PUSCH transmission resources carrying uplink services when the terminal device has uplink services to transmit.

[0107] The physical layer priorities 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).

[0108] For example, when the PUCCH carries an SR, its physical layer priority is determined by the priority corresponding to the carried SR, and the priority corresponding to each SR is configured by high-layer signaling.

[0109] For example, when the PUCCH carries the HARQ-ACK of the SPS PDSCH or the HARQ-ACK of the PDCCH indicating the release of SPS resources, its physical layer priority is determined by the HARQ-ACK codebook number configured for the SPS PDSCH by the high-layer signaling. Among them, the HARQ-ACK codebook corresponding to number 0 has a low priority, and the HARQ-ACK codebook corresponding to number 1 has a high priority.

[0110] For example, when PUCCH carries CSI, its physical layer priority defaults to low priority. CSI can be periodic CSI or semi-persistent CSI (SP-CSI).

[0111] Exemplarily, the DCI used by the PDCCH includes a priority indication field. When the PDCCH schedules a PDSCH, the priority of the PUCCH carrying the HARQ-ACK of the PDSCH can be indicated by the priority indication field; or, when the PDCCH schedules a PUSCH, the priority of the scheduled PUSCH can be indicated by the priority indication field, where the PUSCH includes a PUSCH carrying a transport block (TB) and / or a PUSCH carrying aperiodic channel state information (A-CSI). For a PUSCH carrying SP-CSI, its priority can be obtained by activating the priority indication field in the DCI of the PUSCH carrying SP-CSI.

[0112] Exemplarily, when the DCI used by the PDCCH does not include a priority indication field, or when the higher layer signaling does not configure a priority, the default priority is low.

[0113] In the 5G NR system, five PUCCH formats (hereinafter referred to as PF) are defined: NR PUCCH format 0, 1, 2, 3, and 4. PF 0 and 1 can carry 1 to 2 bits of UCI transmission, and PF 2, 3, and 4 can carry more than 2 bits of UCI transmission. PF 0 and 2 are short PUCCHs, occupying 1 to 2 symbols for transmission, and PF 1, 3, and 4 are long PUCCHs, occupying 4 to 14 symbols for transmission.

[0114] For example, SR can be transmitted using PF 0 or 1, and HARQ-ACK can be transmitted using any one of five PF types.

[0115] The 5G NR system does not support the simultaneous transmission of multiple PUCCHs on a single PUCCH carrier. When multiple UCIs with different physical layer priorities are multiplexed and transmitted on the same uplink channel, resource conflicts may occur. For example, on the same carrier, there is overlap between the symbols occupied by uplink channels with different priorities. To avoid the power limitation caused by the increase in peak-to-average power ratio (PAPR) due to conflicts, it is necessary to transmit only the UCI with higher physical layer priority in the conflicting channel and discard the UCI with lower physical layer priority, which may affect low-priority services.

[0116] For example, if the low-priority HARQ-ACK is discarded, the low-priority downlink transmission will not be able to obtain feedback in time, resulting in unnecessary retransmission; if the low-priority SR is discarded, the base station will not be able to obtain the scheduling request of the low-priority service, so the base station will not send the uplink scheduling permission (uplink grant, ULgrant) to the terminal device in time, resulting in the uplink service cannot be sent in time.

[0117] In addition, for terminal devices that simultaneously have unicast and multicast (or broadcast) services, conflicts may also occur in the HARQ-ACKs of the corresponding unicast and multicast (or broadcast) services.

[0118] In view of this, an embodiment of the present application provides a UCI transmission method and device, which can support multiplexing and transmission of UCI of different priorities on the same channel on the same carrier, so as to avoid discarding UCI carried on the low-priority uplink channel and causing impact on low-priority services.

[0119] In one possible implementation, when predetermined time conditions are met, UCI multiplexing transmission can be performed on multiple PUCCHs according to different UCI types and the PF used by the UCI. In this multiplexing transmission method, HARQ-ACK and SR are configured with different NR PFs, including the following:

[0120] (1) When the PUCCH carrying SR overlaps with the PUCCH carrying HARQ-ACK, and the PUCCH carrying HARQ-ACK uses PF 0 (the PUCCH carrying SR can use PF 0 or PF 1), SR and HARQ-ACK are multiplexed on the PUCCH resources of HARQ-ACK. That is, on the PUCCH resources of HARQ-ACK, HARQ-ACK is transmitted by selecting the cyclic shift (CS) corresponding to the HARQ-ACK when there is a positive SR or a negative SR, thereby implicitly expressing the positive SR or the negative SR.

[0121] (2) When the PUCCH carrying SR overlaps with the PUCCH carrying HARQ-ACK, and the PUCCH carrying SR uses PF 0 and the PUCCH carrying HARQ-ACK uses PF 1, the SR is discarded, that is, no multiplexing transmission is performed at this time.

[0122] (3) When the PUCCH carrying SR overlaps with the PUCCH carrying HARQ-ACK, and the PUCCH carrying SR uses PF 1 and the PUCCH carrying HARQ-ACK also uses PF 1, when there is a positive SR, HARQ-ACK is transmitted on the PUCCH resources of SR, thereby implicitly expressing the simultaneous presence of SR transmission by using the PUCCH resources corresponding to SR to transmit HARQ-ACK; when there is a negative SR, HARQ-ACK is transmitted on the PUCCH resources of HARQ-ACK.

[0123] (4) When the PUCCH carrying SR overlaps with the PUCCH carrying HARQ-ACK, and the PUCCH carrying HARQ-ACK uses PF 2, 3, or 4 (the PUCCH carrying SR can use PF 0 or PF 1), a PUCCH resource set is determined according to the total number of bits of SR and HARQ-ACK, and a PUCCH resource is determined in the determined PUCCH resource set according to the PUCCH resource indication field in the DCI corresponding to HARQ-ACK, for simultaneous transmission of SR and HARQ-ACK, where SR is K bits, indicating the SR status (which one is positive, or both are negative) of the X SRs overlapping with HARQ-ACK, that is, regardless of whether the SR is positive or negative, a K-bit SR is always transmitted to avoid changes in the number of UCI bits transmitted on the PUCCH resource of HARQ-ACK due to the SR status.

[0124] In the above possible implementations, different multiplexing transmission schemes need to be defined for different UCI bit numbers and combinations of different PFs, which results in complex operations.

[0125] In addition, when the PUCCH carrying an SR (regardless of whether it is positive or negative) uses PF 0 or 1, and the PUCCH carrying HARQ-ACK uses PF 2, 3, or 4, the SR and HARQ-ACK can be transmitted simultaneously on one PUCCH resource. However, when the PUCCH carrying HARQ-ACK uses PF 0 or 1, that is, when transmitting a 1-bit or 2-bit HARQ-ACK, the SR and HARQ-ACK cannot be explicitly transmitted simultaneously on one PUCCH resource.

[0126] In view of this, the UCI transmission method of the embodiment of the present application is proposed for the situation where the PUCCH carrying HARQ-ACK uses PF0 or 1 and needs to multiplex and transmit 1 or 2 bits of UCI. By increasing bits or adopting a coding method that supports smaller bits, it helps to achieve multiple types of UCI in the case of a small number of bits (that is, the number of UCI bits is 1 or 2) when there is a conflict. Multiplexing and transmission, this can avoid the impact caused by discarding a certain type of UCI, and is convenient to operate and easy to implement.

[0127] It should be understood that the UCI transmission method provided in the embodiment of the present application can also be applied to the multiplexing and transmission of multiple types of UCI when there is a conflict in the case of a large bit number (i.e., the number of UCI bits is greater than 2). The present application does not limit the number of UCI bits.

[0128] The following combination Figure 2 , the UCI transmission method provided in this application is described in detail.

[0129] For example, Figure 2 2 is a schematic flowchart of a UCI transmission method 200 provided in an embodiment of the present application, which can be executed by a terminal device. The method 200 includes the following steps:

[0130] S201: Determine whether the number of bits of a UCI sequence exceeds a first preset threshold.

[0131] The UCI sequence includes a first UCI and a second UCI, and the first uplink channel carrying the first UCI and the second uplink channel carrying the second UCI overlap in the time domain, or the transmission time interval between the first uplink channel carrying the first UCI and the second uplink channel carrying the second UCI is less than a second preset threshold.

[0132] S202: When it is determined that the number of bits of the UCI sequence does not exceed the first preset threshold, encode the UCI sequence using a first encoding method, or add padding bits or placeholder bits to the UCI sequence until the total number of bits exceeds the first preset threshold, obtain a padded UCI sequence, and encode the padded UCI sequence using a second encoding method.

[0133] S203: Transmit the encoded first UCI sequence and the second UCI sequence on the same uplink channel.

[0134] In an embodiment of the present application, when a first uplink channel carrying a first UCI conflicts with a second uplink channel carrying a second UCI, a terminal device may encode different UCIs with different bit numbers using a coding method, thereby achieving the purpose of transmitting multiple different UCIs on the same uplink channel. When transmitting UCI using a coding method, the content of the UCI sequence is different when determining whether the number of bits of the UCI sequence exceeds a first preset threshold based on different coding rules. If the first UCI and the second UCI are jointly coded, that is, information of the first UCI and the second UCI are concatenated together for encoding, when determining whether the number of bits of the UCI sequence exceeds the first preset threshold in the above S201, the UCI sequence refers to the sequence after the first UCI and the second UCI are concatenated. That is, in this case, the UCI sequence including the first UCI and the second UCI refers to the sequence after the first UCI and the second UCI are concatenated. If the first UCI and the second UCI are independently coded, that is, the first UCI and the second UCI are encoded separately, when determining whether the number of bits of the UCI sequence exceeds the first preset threshold in the above S201, the UCI sequence refers to one of the first UCI and the second UCI. For example, when the first UCI is encoded, it refers to the first UCI, and when the second UCI is encoded, it refers to the second UCI. Because the first UCI and the second UCI are to be transmitted simultaneously, that is, the terminal needs to encode the first UCI and the second UCI separately, that is, both UCIs will be encoded. That is, in this case, the UCI sequence including the first UCI and the second UCI refers to processing the first UCI and the second UCI separately.

[0135] Correspondingly, according to different encoding modes of the terminal device, the network device needs to determine a corresponding decoding mode to decode the UCI sequence after the encoding and other processing, so as to correctly decode the first UCI and the second UCI.

[0136] The first type of coding mentioned above is repetition coding and RM coding, where repetition coding can be the coding method used when 1 or 2 bits of HARQ-ACK are transmitted on PUSCH; RM coding can be RM (24, O1) coding or RM (32, O2) coding, O1 and O2 are the number of bits of the UCI sequence to be encoded input to the encoder, O1 can be 1 to 13, and O2 can be 1 to 11.

[0137] The second type of coding mentioned above includes RM coding, Polar coding, low density parity check (LDPC) coding, tail biting convolutional coding (TBCC) coding or Turbo coding.

[0138] The first preset threshold may be 2 bits (other numbers of bits are not excluded).

[0139] The above-mentioned filling bits or placeholder bits can be repeated UCI bits or preset bit states, for example, fixedly filled with "1" or "0", or a fixed sequence of "1" and "0".

[0140] It should be understood that the physical layer priorities of the first UCI and the second UCI may be the same or different.

[0141] Optionally, the first UCI and the second UCI are respectively one of the UCI corresponding to the unicast service and the UCI corresponding to the multicast service, for example, the first UCI is the UCI corresponding to the unicast service, and the second UCI is the UCI corresponding to the multicast service; or, the first UCI is the UCI corresponding to the multicast service, and the second UCI is the UCI corresponding to the unicast service.

[0142] Method 200 can be executed in the same carrier group, that is, the first uplink channel carrying the first UCI and the second uplink channel carrying the second UCI belong to the same carrier group. In other words, the above-mentioned conflict refers to the conflict occurring in the same carrier group, and the conflict between uplink channels in different carriers may not be executed according to method 200.

[0143] The method 200 may be performed when the first UCI and the second UCI are allowed or configured to be multiplexed and transmitted on the same uplink channel.

[0144] The conflict between the first uplink channel and the second uplink channel can be understood as: the first uplink channel and the second uplink channel overlap in the time domain; or the transmission time interval between the first uplink channel and the second uplink channel is less than the first preset threshold.

[0145] It should be understood that when the first uplink channel and the second uplink channel do not overlap in the time domain, the transmission time interval between the end symbol of the first uplink channel (assuming that the first uplink channel is a channel with an earlier 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) may be less than the first preset threshold, resulting in the two channels not overlapping but unable to be transmitted continuously (for example, in scenarios where RF devices need to be adjusted in high-frequency transmission). Therefore, the first UCI and the second UCI carried on the two channels need to be multiplexed and transmitted on the same uplink channel.

[0146] In the embodiment of the present application, there are two ways to process the first UCI and the second UCI: one is to process the first UCI and the second UCI jointly, and the other is to process the first UCI and the second UCI independently. The following first introduces in detail different encoding methods of UCIs with different bit numbers under the joint processing method.

[0147] As an optional embodiment, when the first UCI and the second UCI adopt a joint coding method (that is, the first type of coding method encodes the cascade sequence of the first UCI and the second UCI, that is, the first UCI and the second UCI are encoded together), the terminal device cascades the first UCI and the second UCI to obtain a first cascade UCI sequence; when it is determined that the total number of bits of the first cascade UCI sequence does not exceed the first preset threshold, the first type of coding method is used to encode the first UCI cascade sequence, or, padding bits or placeholder bits are added to the first cascade UCI sequence until the total number of bits of the first cascade UCI sequence exceeds the first preset threshold, to obtain the padded first cascade UCI sequence, and the second type of coding method is used to encode the padded first cascade UCI sequence.

[0148] As an optional embodiment, the first UCI is an A1-bit HARQ-ACK, and the second UCI is an A2-bit HARQ-ACK, wherein A1 and A2 are equal or unequal, and A1+A2 does not exceed the first preset threshold; or, the first UCI is an A3-bit HARQ-ACK, and the second UCI is SR, and A3 does not exceed the first preset threshold.

[0149] The following is Figure 3 The first UCI shown is a high-priority HARQ-ACK with an A1 bit (hereinafter referred to as HP AN), the second UCI is a low-priority HARQ-ACK with an A2 bit (hereinafter referred to as LP AN), A1 and A2 are equal or unequal, A1 + A2 does not exceed the first preset threshold, and the uplink channel is a PUCCH. As an example, different encoding methods for UCIs with different bit numbers in joint processing are described in detail. There is a conflict between the PUCCH carrying the HP AN and the PUCCH carrying the LP AN.

[0150] exist Figure 3 In the example, when a HP DCI schedules a PDSCH, the priority indication field in the HP DCI can be used to indicate that the priority of the PUCCH carrying the HARQ-ACK of this PDSCH is high priority, so a high priority HARQ-ACK can be determined, namely the HP AN. Similarly, the priority indication field in the LP DCI can be used to indicate that the priority of the PUCCH carrying the HARQ-ACK of this PDSCH is low priority, so a low priority HARQ-ACK can be determined, namely the LP AN. Figures 4 to 6 It is similar to the description here, so I will not repeat it here.

[0151] It is assumed that the terminal device can support HARQ-ACK of different priorities to be multiplexed and transmitted on the same PUCCH (i.e., simultaneous transmission), where the first UCI and the second UCI are in the same carrier group. For example, when a secondary carrier component (SCC) is configured to transmit PUCCH, the primary and secondary PUCCH groups are each a carrier group; for example, in a dual-connection scenario, when a secondary cell group (SCG) is configured, the master cell group (MCG) and the SCG are each a carrier group.

[0152] For example, when the value of A1 is 1, the value of A2 is 1, and the second preset threshold is 2 bits, a 1-bit HP AN and a 1-bit LP AN are concatenated to obtain a 2-bit first concatenated UCI sequence. Since the number of bits of the first concatenated UCI sequence does not exceed the first preset threshold, the following two cases of multiplexing and transmission using encoding methods are considered:

[0153] (1) The terminal device encodes the 2-bit first concatenated UCI sequence using repetition coding or RM coding, and then transmits the processed first concatenated UCI sequence through a determined PUCCH resource after undergoing various processing such as scrambling, modulation, and mapping.

[0154] Exemplarily, the terminal device may determine a PUCCH resource set according to the number of bits of the first cascaded UCI sequence, and then determine a PUCCH resource in the PUCCH resource set according to the PUCCH resource indication field in the DCI corresponding to the AN for multiplexing transmission.

[0155] It should be understood that the steps for the terminal device to determine PUCCH below are the same as here, so they will not be repeated.

[0156] (2) The terminal device adds a 1-bit padding bit or placeholder bit to the end of the 2-bit first concatenated UCI sequence or at any other position to obtain a 3-bit padded first concatenated UCI sequence. The terminal device encodes the 3-bit padded first concatenated UCI sequence using RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding. After various processing such as scrambling, modulation, and mapping, the processed new UCI concatenated sequence is transmitted through the determined PUCCH resources.

[0157] Exemplarily, the terminal device may determine a PUCCH resource set according to the number of bits of the padded first cascaded UCI sequence, and then determine a PUCCH resource in the PUCCH resource set according to the PUCCH resource indication field in the DCI corresponding to the AN for multiplexing transmission.

[0158] The above-mentioned 1-bit added filling bit or placeholder bit can be adding 1 bit of "0", adding 1 bit of "1", adding 1 bit of HP AN repeated information, or adding 1 bit of LP AN repeated information, etc., and there can also be any other forms of filling bits and placeholder bits, which are not limited in the embodiments of the present application.

[0159] For example, assuming that the value of A1 is 1, the value of A2 is 2, and the second preset threshold is 2 bits, a 1-bit HP AN and a 2-bit LP AN are concatenated to obtain a 3-bit first concatenated UCI sequence. Since the number of bits in the first concatenated UCI sequence exceeds the first preset threshold, the following encoding methods are considered for multiplexing and transmission:

[0160] The terminal device uses RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to encode the 3-bit AN cascade sequence, and then after different processing such as scrambling, modulation, mapping, etc., transmits the processed first cascade UCI sequence through the determined PUCCH resource.

[0161] In the embodiment of the present application, in the joint processing mode, if the total number of bits of the concatenated sequence of the first UCI and the second UCI exceeds a first preset threshold, the second type of encoding mode may be directly used for encoding.

[0162] For the network device, the processing process is similar to the execution steps of the above-mentioned terminal device. For example, the network device can determine that the terminal device adds 1 bit of padding bit or placeholder bit to the 2-bit first cascade UCI sequence to obtain a new sequence, so it can be determined that the number of bits of the new sequence input to the encoder is 3, and then the target coding information obtained after encoding and other processing is received on the determined PUCCH resource, and the target coding information is decoded using RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to obtain 3-bit information, and the first 2 bits are extracted as HPAN and LP AN respectively.

[0163] In the small-bit UCI multiplexing transmission scenario, the values of A1 and A2 can be 1 or 2 respectively, and the values of A1 and A2 can be equal or unequal.

[0164] In the joint processing mode, the first UCI can also be a high-priority SR (hereinafter referred to as HP SR) or a low-priority SR (hereinafter referred to as LP SR), and the second UCI can also be an HP SR or LP SR, or other different service types, such as CSI. The embodiment of the present application is not limited here.

[0165] As an optional embodiment, when the first UCI is A3-bit HARQ-ACK and the second UCI is SR, the method specifically includes:

[0166] Method 1: Determine the number of SR bits to be X bits, concatenate the X-bit SR with the first UCI to obtain a third concatenated UCI sequence, and encode the third concatenated UCI sequence using the second encoding method; or

[0167] Method 2: Determine that the number of SR bits is X bits, concatenate the X-bit SR with the first UCI to obtain a third concatenated UCI sequence, and when it is determined that the total number of bits of the third concatenated UCI sequence does not exceed the first preset threshold, encode the third concatenated UCI sequence using the first type of encoding method, or add padding bits or placeholder bits to the third concatenated UCI sequence until the total number of bits of the third concatenated UCI sequence exceeds the first preset threshold, thereby obtaining a padded third concatenated UCI sequence, and encode the padded third concatenated UCI sequence using the second type of encoding method; when it is determined that the total number of bits of the third concatenated UCI sequence exceeds the predetermined threshold, encode the third concatenated UCI sequence using the second type of encoding method;

[0168] Wherein, X=ceil(log2(K+1)), ceil() is rounded up, and K is the number of configured SRs or the number of SRs that meet the following conditions: there is overlap with the first uplink channel and / or the second uplink channel in the time domain, or the transmission time interval between the first uplink channel and / or the second uplink channel is less than the second preset threshold.

[0169] like Figure 4 As shown, when there is an LP SR overlapping with the A3-bit HP AN, the terminal device determines that the number of SR bits X is 1. When the number of HP AN bits is 1 and the first preset threshold is 2 bits, the 1-bit HP AN and the 1-bit LP SR are concatenated to obtain a 2-bit third concatenated UCI sequence. Since the number of bits of the third concatenated UCI sequence does not exceed the first preset threshold, the case of multiplexing and transmission using the above method 2 is considered:

[0170] (1) The terminal device encodes the 2-bit third concatenated UCI sequence using repetition coding or RM coding, and then transmits the processed third concatenated UCI sequence through a determined PUCCH resource after undergoing different processing such as scrambling, modulation, and mapping.

[0171] (2) The terminal device adds a 1-bit padding bit or placeholder bit to the end of the 2-bit third-concatenated UCI sequence or any other position to obtain a 3-bit padded third-concatenated UCI sequence, and encodes the 3-bit padded third-concatenated UCI sequence using RM coding, Polar coding, low-density parity check (LDPC) coding, tail-biting convolution (TBCC) coding, or Turbo coding. After various processing such as scrambling, modulation, and mapping, the processed third-concatenated UCI sequence is transmitted through the determined PUCCH resources.

[0172] The terminal device determines that the number of SR bits, X, is 1. When the number of HP AN bits is 2 and the first preset threshold is 2 bits, the 2-bit HP AN and the 1-bit SR are concatenated to obtain a 3-bit third concatenated UCI sequence. Since the number of bits of the UCI concatenated sequence exceeds the first preset threshold, the case of multiplexing and transmission using method 1 above is considered:

[0173] The terminal device encodes the UCI cascade sequence using RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding, and then transmits the third cascade UCI sequence through the determined PUCCH resources after different processing such as scrambling, modulation, and mapping.

[0174] It should be understood that the above-mentioned SR can also be an HP SR, that is, the priority of the SR is the same as that of the HP AN, and the embodiments of the present application are not limited here; the number of bits of the above-mentioned SR may also be other values such as 2 bits or 3 bits. When the number of bits of the SR is 2 bits, it can be directly cascaded with 1 or 2 bits of HP AN, and the cascaded UCI sequence can be encoded using RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding. After different processing such as scrambling, modulation, mapping, etc., the processed cascaded UCI sequence is transmitted through the determined PUCCH resources.

[0175] like Figure 5As shown, when there are multiple LP SRs (for example, LP SR1 and LP SR2) overlapping with the HP AN, the terminal device determines that the number of bits X of the LP SR is 2. Assuming that the number of bits of the HP AN is 1 and the second preset threshold is 2 bits, the 1-bit HP AN is concatenated with the 2-bit LP SR to obtain a 3-bit UCI concatenated sequence. Since the number of bits of the UCI concatenated sequence is greater than the second preset threshold, RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding is used to encode the 3-bit UCI concatenated sequence. After different processing such as scrambling, modulation, and mapping, the processed UCI concatenated sequence is transmitted through the determined PUCCH resources.

[0176] The above description is about the joint processing method of two UCIs of different priorities, the first UCI and the second UCI. The following describes in detail the joint processing method of the terminal device when a third UCI is present, where the third UCI has the same priority as at least one of the first UCI and the second UCI, or has a different priority from both the first UCI and the second UCI.

[0177] As an optional embodiment, when the first UCI is A1-bit HARQ-ACK and the second UCI is A2-bit HARQ-ACK, the method further includes:

[0178] If there is still overlap between the third uplink channel carrying the SR and the first uplink channel and / or the second uplink channel in the time domain, or the transmission time interval between the third uplink channel carrying the SR and the first uplink channel and / or the second uplink channel is less than the second preset threshold, one of the following methods is adopted:

[0179] Method 1: Determine the number of SR bits to be X bits, concatenate the X-bit SR with the first UCI and the second UCI to obtain a second concatenated UCI sequence, and encode the second concatenated UCI sequence using the second coding mode;

[0180] Method 2: Determine that the number of SR bits is X bits, concatenate the X-bit SR with the first UCI and the second UCI to obtain a second concatenated UCI sequence, and when it is determined that the total number of bits of the second concatenated UCI sequence does not exceed the first preset threshold, encode the second concatenated UCI sequence using the first type of encoding method, or add padding bits or placeholder bits to the second concatenated UCI sequence until the total number of bits of the second concatenated UCI sequence exceeds the first preset threshold, obtain a padded second concatenated UCI sequence, and encode the padded second concatenated UCI sequence using the second type of encoding method; when it is determined that the total number of bits of the second concatenated UCI sequence exceeds the first preset threshold, encode the second concatenated UCI sequence using the second type of encoding method;

[0181] Where X = ceil(log2(K+1)), ceil() is rounded up, and K is the number of configured SRs or the number of SRs that meet the following conditions:

[0182] There is overlap with the first uplink channel and / or the second uplink channel in the time domain, or the transmission time interval between the first uplink channel and / or the second uplink channel is less than the second preset threshold.

[0183] The following describes the process of multiplexing and transmitting three UCIs in joint processing, taking as an example a case where the first UCI is an A1-bit HP AN, the second UCI is an A2-bit LP AN, and the third UCI is an X-bit HPSR, with the uplink channel being the PUCCH. The PUCCH carrying the HP AN conflicts with the PUCCH carrying the LP AN, and the PUCCH carrying the HP SR conflicts with the PUCCH carrying the HP AN and / or the PUCCH carrying the LP AN.

[0184] For example, when there is Figure 6 When an HP SR overlaps with an AN (HP AN and / or LP AN), the terminal device determines that the value of X is 1. When the value of A1 is 1, the value of A2 is 1, and the first preset threshold is 2 bits, the terminal device concatenates a 1-bit HP AN, a 1-bit LP AN, and a 1-bit HP SR to obtain a 3-bit second concatenated UCI sequence. Since the number of bits in the second concatenated UCI sequence exceeds the first preset threshold, no padding bits or placeholder bits need to be added. Therefore, the following case of multiplexing and transmission using encoding is considered:

[0185] The terminal device encodes the second cascaded UCI sequence using RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding.

[0186] For network devices, the processing process is similar to the execution steps of the above-mentioned terminal device. The network device can determine that the number of bits of the second cascade UCI sequence of the terminal device input encoder is 3, and then receive the target coding information obtained after encoding and other processing on the determined PUCCH resource, and decode the target coding information using RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to obtain 3 bits of information, and extract 1 bit of HP AN, 1 bit of LP AN and 1 bit of HP SR respectively.

[0187] The above describes the process of multiplexing and transmitting multiple UCIs on the same uplink channel in a coded manner in a joint processing mode through specific examples. The following describes the process of multiplexing and transmitting UCIs in an independent processing mode in detail.

[0188] The following describes the process of multiplexing two UCIs in independent processing mode, taking the case where the first UCI is an HP AN with A1 bits, the second UCI is an LP AN with A2 bits, and the uplink channel is a PUCCH. The PUCCH carrying the HP AN and the PUCCH carrying the LP AN conflict.

[0189] As an optional embodiment, the terminal device determines whether the number of bits of the first UCI and the second UCI exceeds the first preset threshold respectively; when it is determined that the number of bits of the first UCI does not exceed the first preset threshold, the first UCI is encoded using the first type of encoding method, or, padding bits or placeholder bits are added to the first UCI until the number of bits of the first UCI exceeds the first preset threshold, the padded first UCI sequence is obtained, and the padded first UCI sequence is encoded using the second type of encoding method; and / or, when it is determined that the number of bits of the second UCI does not exceed the first preset threshold, the second UCI is encoded using the first type of encoding method, or, padding bits or placeholder bits are added to the second UCI until the number of bits of the second UCI exceeds the first preset threshold, the padded second UCI sequence is obtained, and the padded second UCI sequence is encoded using the second type of encoding method.

[0190] In the independent processing mode, the terminal device can encode the UCI whose number of bits in the first UCI and the second UCI does not exceed the first preset threshold using the first type of encoding method, or the terminal device can add padding bits or placeholder bits to the UCI that does not exceed the first preset threshold until the number of bits of the UCI sequence after the addition exceeds the first preset threshold, and then use the second type of encoding method to encode the UCI sequence after the padding bits.

[0191] As an optional embodiment, the first UCI is an A4-bit HARQ-ACK, and the second UCI is an A5-bit HARQ-ACK, wherein A4 and A5 are equal or unequal, and at least one of A4 and A5 does not exceed the first preset threshold; or, the first UCI is an A6-bit HARQ-ACK, and the second UCI is an SR, wherein at least one of the SR bits and A6 does not exceed the first preset threshold, the number of SR bits is X=ceil(log2(K+1)), ceil() is rounded up, K is the number of configured SRs or the number of SRs that meet the following conditions: there is overlap with the first uplink channel and / or the second uplink channel in the time domain, or the transmission time interval between the first uplink channel and / or the second uplink channel is less than the second preset threshold.

[0192] The following describes the process of multiplexing two UCIs in independent processing mode, taking the case where the first UCI is an HP AN with A4 bits, the second UCI is an LP AN with A5 bits, and the uplink channel is a PUCCH. The PUCCH carrying the HP AN and the PUCCH carrying the LP AN conflict.

[0193] For example, when the value of A4 is 1, the value of A5 is 1, and the first preset threshold is 2 bits, since the values of A4 and A5 do not exceed the first preset threshold, the following two cases of multiplexing and transmission using encoding methods are considered:

[0194] (1) The terminal device uses repetition coding or RM coding to independently encode the 1-bit HP AN and 1-bit LP AN respectively, and then transmits the processed HP AN and LP AN through the determined PUCCH resources after different processing such as scrambling, modulation, and mapping.

[0195] Exemplarily, a PUCCH resource set can be determined based on the total number of bits 2 of 1-bit HP AN and 1-bit LP AN, and then a PUCCH resource can be determined in the PUCCH resource set based on the PUCCH resource indication field in the DCI corresponding to the AN for multiplexing transmission.

[0196] (2) The terminal device adds 2-bit padding bits or placeholder bits to the tail of the 1-bit HP AN and the 1-bit LP AN or at any other position to obtain a 3-bit HP new sequence and a 3-bit LP new sequence, and uses RM coding, Polar coding, low-density parity check LDPC coding, tail-biting convolution TBCC coding or Turbo coding to encode the 3-bit HP new sequence and the 3-bit LP new sequence respectively. After different processing such as scrambling, modulation, mapping, etc., the processed HP new sequence and LP new sequence are transmitted through the determined PUCCH resources.

[0197] Exemplarily, a PUCCH resource set can be determined based on the total number of bits 6 of the 3-bit HP new sequence and the 3-bit LP new sequence, and then a PUCCH resource is determined in the PUCCH resource set based on the PUCCH resource indication field in the DCI corresponding to the AN for multiplexing transmission.

[0198] Similarly, for the network device, it can be determined that the terminal device has added 2 bits of padding bits or placeholder bits to the 1-bit HP AN, and added 2 bits of padding bits or placeholder bits to the 1-bit LP AN. Therefore, the network device can determine that the new HP sequence and the new LP sequence input to the encoder by the terminal device are both 3 bits, and then the new HP sequence and the new LP sequence after encoding and other processing can be received on the PUCCH resource determined by 6 bits of information (the sum of the number of bits of the 3-bit HP new sequence and the 3-bit LP new sequence), and the information corresponding to the HP AN and the information corresponding to the LP AN can be extracted from the received information. The information corresponding to the HP AN and the information corresponding to the LP AN are then independently decoded using RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to obtain 3-bit HP information and 3-bit LP information, and the first 1 bit is extracted as the HP AN and LP AN, respectively.

[0199] For example, when the value of A4 is 3, the value of A5 is 2, and the first preset threshold is 2 bits, since the value of A4 exceeds the first preset threshold and the value of A5 does not exceed the first preset threshold, the following case of multiplexing and transmission using encoding is considered:

[0200] The terminal device uses RM coding, Polar coding, low-density parity check LDPC coding, tail-biting convolution TBCC coding or Turbo coding to independently encode the 3-bit HP AN; adds 1 bit of padding bit or placeholder bit to the tail or any other position of the 2-bit LPAN to obtain a 3-bit padded LPAN sequence, and uses RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to independently encode the 3-bit padded LPAN sequence; then performs different processing such as scrambling, modulation, mapping, etc., and transmits the processed HP AN and LPAN sequences through the determined PUCCH resources.

[0201] In an embodiment of the present application, under an independent coding method, a UCI sequence exceeding a first preset threshold can be directly encoded using the second type of coding method; a UCI sequence not exceeding the first preset threshold can be padded with bits until it exceeds the first preset threshold, or it can be directly encoded using the first type of coding method.

[0202] For example, when the value of A4 is 3, the value of A5 is 1, and the first preset threshold is 2 bits. Since the value of A4 exceeds the first preset threshold and the value of A5 does not exceed the first preset threshold, the following two cases of multiplexing transmission using encoding methods are considered:

[0203] (1) The terminal device independently encodes the 1-bit LPAN using repetition coding or RM coding, and independently encodes the 3-bit HPAN using RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding. The encoded HPAN and LPAN are then subjected to different processing such as scrambling, modulation, and mapping, and then transmitted through the determined PUCCH resources.

[0204] Exemplarily, a PUCCH resource set can be determined based on the total number of bits 4 of the 3-bit HP AN and the 1-bit LP AN, and then a PUCCH resource can be determined in the PUCCH resource set for multiplexing transmission based on the PUCCH resource indication field in the DCI corresponding to the AN.

[0205] (2) The terminal device independently encodes the 3-bit HP AN using RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding; adds 2-bit padding bits or placeholder bits to the end of the 1-bit LP AN or at any other position to obtain a 3-bit LP new sequence, and independently encodes the 3-bit LP new sequence using RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding; then performs different processing on the encoded HP sequence and LP new sequence, such as scrambling, modulation, and mapping, and transmits the processed HP AN and LP new sequence through the determined PUCCH resources.

[0206] Exemplarily, a PUCCH resource set can be determined based on the total number of bits 6 of the 3-bit HP AN and the 3-bit LP new sequence, and then a PUCCH resource can be determined in the PUCCH resource set for multiplexing transmission based on the PUCCH resource indication field in the DCI corresponding to the AN.

[0207] It should be understood that in the process of multiplexing and transmitting two UCIs under the above-mentioned independent processing mode, the first UCI can be HP SR or LP SR, and the second UCI can also be HP SR or LP SR, or other different service types, such as CSI, and the embodiment of the present application is not limited here.

[0208] The embodiments of the present application do not limit the values of A1 and A2. For example, the values of A1 and A2 can both be 2, or the value of A1 is 2 and the value of A2 is 1, or the value of A1 is 1 and the value of A2 is 2. The processing process is the same as above, except that for a 2-bit AN, 1-bit padding bit or placeholder bit needs to be added, and for a 1-bit AN, 2-bit padding bits or placeholder bits need to be added.

[0209] It should be understood that the value of the first preset threshold in the embodiment of the present application may also be any other value and is not limited here.

[0210] For the network device, the processing process is similar to the execution steps of the above-mentioned terminal device. The network device can determine that the terminal device adds 1 bit of padding bit or placeholder bit to the 2-bit HP cascade sequence, and determines that 2 bits of padding bit or placeholder bit are added to the 1-bit LPAN. Therefore, the network device determines that the number of bits of the new HP sequence and the new LP sequence input to the encoder of the terminal device are both 3, and then the network device can receive the new HP sequence and the new LP sequence obtained after encoding and other processing on the determined PUCCH resource, and respectively extract the information corresponding to the new HP sequence and the information corresponding to the new LP sequence from the received information, and then respectively decode them to obtain 3-bit HP information and 3-bit LP information, and extract the first 2 bits from the 3-bit HP information as HP AN and HP SR, respectively, and extract the first 1 bit from the 3-bit LP information as LP AN.

[0211] For example, Figure 4 As shown in the figure, it is assumed that the first UCI is an A6-bit HP AN and the second UCI is an LP SR. The terminal device determines that the number of bits X of the LP SR is 1. When the value of A6 is 1 and the first preset threshold is 2 bits, since the value of A1 does not exceed the first preset threshold and the value of X does not exceed the first preset threshold, the following encoding method is considered for multiplexing transmission:

[0212] The terminal device adds 2 bits of padding bits or placeholder bits to the end of the 1-bit HP AN or other arbitrary positions to obtain a 3-bit HP AN new sequence, and uses RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to independently encode the 3-bit HP AN new sequence; adds 2 bits of padding bits or placeholder bits to the end of the 1-bit LP SR or other arbitrary positions to obtain a 3-bit LP SR new sequence, and uses RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to independently encode the 3-bit LP SR new sequence; then performs different processing such as scrambling, modulation, and mapping on the encoded HP AN new sequence and LP SR new sequence, and transmits the processed HP AN new sequence and LP SR new sequence through the determined PUCCH resources.

[0213] For example, in Figure 5 In the case where two LPSRs overlap with HPANs, the terminal device determines that the number of LPSR bits, X, is 2. When the value of A6 is 1 and the first preset threshold is 2 bits, since the value of A6 does not exceed the first preset threshold and the value of X does not exceed the first preset threshold, the following case of multiplexing transmission using encoding is considered:

[0214] The terminal device adds 2 bits of padding bits or placeholder bits to the end of the 1-bit HP AN or other arbitrary positions to obtain a 3-bit HP AN new sequence, and uses RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to independently encode the 3-bit HP AN new sequence; adds 1 bit of padding bit or placeholder bit to the end of the 2-bit LP SR or other arbitrary positions to obtain a 3-bit LP SR new sequence, and uses RM coding, Polar coding, LDPC coding, TBCC coding or Turbo coding to independently encode the 3-bit LP SR new sequence; then performs different processing such as scrambling, modulation, and mapping on the encoded HP AN new sequence and LP SR new sequence, and transmits the processed HP AN new sequence and LP SR new sequence through the determined PUCCH resources.

[0215] For example, when the number of bits of the HP AN is 1 or 2, and the number of bits of the LP SR exceeds 2 bits (for example, there are more than 2 LP SRs overlapping with the HP AN), it is necessary to add 1 bit or 2 bits to the HP AN and then use the second type of encoding method to encode it, while the LP SR with more than 2 bits can be directly encoded using the second type of encoding method.

[0216] As an optional embodiment, when the first UCI is A1-bit HARQ-ACK and the second UCI is A2-bit HARQ-ACK, if there is still a third uplink channel carrying SR and the first uplink channel and / or the second uplink channel. There is overlap in the time domain, or the transmission time interval between the third uplink channel carrying SR and the first uplink channel and / or the second uplink channel is less than the second preset threshold, further including:

[0217] Determine the number of SR bits to be X bits, concatenate the X-bit SR and the first target UCI to obtain a fourth concatenated UCI sequence, where the first target UCI is one of the first UCI and the second UCI; for each sequence in the fourth concatenated UCI sequence and the second target UCI whose bit number does not exceed the first preset threshold, respectively encode using the first type of encoding method, or add padding bits or placeholder bits until the total number of bits exceeds the first preset threshold, and encode the sequence after the padding bits or placeholder bits are added using the second type of encoding method; for each sequence in the fourth concatenated UCI sequence and the second target UCI whose bit number exceeds the first preset threshold, encode using the second type of encoding method; wherein the second target UCI is the UCI in the first UCI and the second UCI other than the first target UCI.

[0218] In the embodiment of the present application, the first target UCI is a UCI having the same priority as the X-bit SR.

[0219] The following is Figure 6 Taking the example of the first UCI being an A1-bit HP AN, the second UCI being an A2-bit LP AN, and the third UCI being an X-bit HP SR, and the uplink channel being a PUCCH, the process of multiplexing and transmitting the three UCIs in an independent processing mode is described. Among them, the PUCCH carrying the HP AN conflicts with the PUCCH carrying the LP AN, and the PUCCH carrying the HP SR conflicts with the PUCCH carrying the HP AN and / or the PUCCH carrying the LP AN. Figure 6 In (a, b, and c), the starting positions of HP AN, LP AN, and HPSR can vary and may not be aligned, which all belong to this scenario.

[0220] For example, the terminal device determines that the value of X is 1. When the value of A1 is 1, the value of A2 is 1, and the first preset threshold is 2 bits, the target UCI is the HP AN with the same physical layer priority as the HP SR. Because the total number of bits in the concatenated sequence of the HP AN and HP SR does not exceed the first preset threshold, and the number of bits in the LP AN does not exceed the first preset threshold, the following two scenarios are considered for multiplexing transmission using encoding methods:

[0221] (1) The terminal device concatenates a 1-bit HP AN and a 1-bit HP SR with the same priority to obtain a 2-bit HP concatenated sequence. The HP concatenated sequence and the LP AN are independently encoded using repetition coding or RM coding. After various processing steps such as scrambling, modulation, and mapping, the processed HP concatenated sequence and the LP AN are transmitted through the determined PUCCH resources.

[0222] (2) The terminal device concatenates a 1-bit HP AN and a 1-bit HP SR of the same priority to obtain a 2-bit HP concatenated sequence, adds a 1-bit padding bit or placeholder bit to the HP concatenated sequence to obtain a 3-bit new HP sequence, and then uses RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding to encode the new HP sequence; adds 2 bits of padding bits or placeholder bits to the 1-bit LP AN to obtain a 3-bit new LP sequence, and then uses RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding to encode the new LP sequence. After performing different processing such as scrambling, modulation, and mapping on the new HP sequence and the new LP sequence, the processed new HP sequence and the new LP sequence are transmitted through the determined PUCCH resources.

[0223] Exemplarily, one PUCCH resource may be determined for multiplexing transmission according to the total number of bits 6 of the 3-bit HP new sequence and the 3-bit LP new sequence.

[0224] Exemplarily, the terminal device determines that the value of X is 1. When the value of A1 is 2, the value of A2 is 1, and the first preset threshold is 2 bits, since the total number of bits of the concatenated sequence of the HP AN and the HP SR exceeds the first preset threshold, and the number of bits of the LP AN does not exceed the first preset threshold, the following case of multiplexing and transmission using encoding is considered:

[0225] The terminal device concatenates the 2-bit HP AN and 1-bit HP SR of the same priority to obtain a 3-bit HP concatenated sequence. This 3-bit HP concatenated sequence is encoded using RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding. A 2-bit padding bit or placeholder bit is added to the 1-bit LP AN to obtain a 3-bit new LP sequence. This new LP sequence is encoded using RM coding, Polar coding, LDPC coding, TBCC coding, or Turbo coding. The new HP and LP sequences are then subjected to various processing, such as scrambling, modulation, and mapping, before being transmitted using the specified PUCCH resources.

[0226] For example, if the third UCI is LP SR, LP AN and LP SR are concatenated and then independently encoded. The other processing procedures are the same as above and will not be repeated here.

[0227] It should be understood that the execution steps of the above terminal device and the network device are not in any particular order; in the above independent processing of the first UCI, the second UCI, and the third UCI, the processing of the HP and LP independent encoding are not in any particular order;

[0228] In the above embodiment, when the uplink channel is PUSCH, the UCI transmission method provided in this application is still used; in the above embodiment, when the HARQ-ACKs of different priorities are HARQ-ACKs for unicast services and HARQ-ACKs for multicast services, the UCI transmission method provided in this application is still applicable.

[0229] Combined with the above Figures 1 to 6 , describes in detail the UCI transmission method according to the embodiment of the present application, and will be combined with Figure 7 and Figure 8 A UCI transmission device according to an embodiment of the present application is described in detail.

[0230] Figure 7A schematic block diagram of a UCI transmission device 700 provided in an embodiment of the present application is shown. The device 700 includes: a processing module 710 and a sending module 720.

[0231] Among them, the processing module 710 is used to: determine whether the number of bits of the UCI sequence exceeds a first preset threshold, wherein the UCI sequence includes a first UCI and a second UCI, and the first uplink channel carrying the first UCI and the second uplink channel carrying the second UCI overlap in the time domain, or the transmission time interval between the first uplink channel carrying the first UCI and the second uplink channel carrying the second UCI is less than a second preset threshold; the processing module 710 is also used to: when it is determined that the number of bits of the UCI sequence does not exceed the first preset threshold, encode the UCI sequence using a first type of coding method, or add padding bits or placeholder bits to the UCI sequence until the total number of bits exceeds the first preset threshold, obtain a padded UCI sequence, and encode the padded UCI sequence using a second type of coding method; the sending module 720 is used to: transmit the encoded first UCI sequence and the second UCI sequence on the same uplink channel.

[0235] Method 1: Determine the number of SR bits to be X bits, concatenate the X-bit SR with the first UCI and the second UCI to obtain a second concatenated UCI sequence, and encode the second concatenated UCI sequence using the second encoding method;

[0236] Method 2: Determine that the number of SR bits is X bits, concatenate the X-bit SR with the first UCI and the second UCI to obtain a second concatenated UCI sequence. When it is determined that the total number of bits of the second concatenated UCI sequence does not exceed the first preset threshold, encode the second concatenated UCI sequence using the first type of encoding method, or add padding bits or placeholder bits to the second concatenated UCI sequence until the total number of bits of the second concatenated UCI sequence exceeds the first preset threshold, obtain a padded second concatenated UCI sequence, and encode the padded second concatenated UCI sequence using the second type of encoding method. When it is determined that the total number of bits of the second concatenated UCI sequence exceeds the first preset threshold, encode the second concatenated UCI sequence using the second type of encoding method.

[0237] Wherein, X=ceil(log2(K+1)), ceil() is rounded up, and K is the number of configured SRs or the number of SRs that meet the following conditions: there is overlap with the first uplink channel and / or the second uplink channel in the time domain, or the transmission time interval between the first uplink channel and / or the second uplink channel is less than the second preset threshold.

[0238] Optionally, when the first UCI is A3-bit HARQ-ACK and the second UCI is SR, the processing module 710 is configured to:
