TECHNICAL FIELD

The present disclosure relates to the field of communications technologies, and in particular, to an information processing method, a device, and a computer-readable storage medium.

BACKGROUND

In a future communications system, an unlicensed band may be used to supplement a licensed band, to help an operator expand services. To keep consistency with new radio (NR) deployment and maximize NR-based unlicensed access as much as possible, the unlicensed band may be in 5 GHz, 37 GHz, and 60 GHz bands. A large bandwidth (80 or 100 MHz) of the unlicensed band can reduce implementation complexity of a base station and a terminal device.

For a 5G communications system running on an unlicensed band (for example, 5 GHz), interlaced resource blocks (interlace) are used as allocation units for uplink transmission to meet a spectrum occupation requirement in the unlicensed band and increase uplink transmission coverage under a spectral power density requirement. In terms of physical uplink control channel (PUCCH) design, to adapt to the interlaced resource block structure in an unlicensed 5G communications system, enhancement is also made on the basis of PUCCH in a licensed 5G communications system, but the enhancement is based on a 20 MHz bandwidth. In the 20 MHz bandwidth, the PUCCH must occupy at least one entire interlace. However, in some cases, the terminal device does not necessarily need to use such configuration. In these cases, use of the transmission mode in the prior art leads to lower resource utilization.

DETAILED DESCRIPTION OF EMBODIMENTS

FIG. 1is a flowchart of an information processing method according to this embodiment of the present disclosure. As shown inFIG. 1, the method includes the following step.

Step101: In a case that a PUCCH transmission format based on an interlace structure is scheduled for a terminal device, determine, based on a characteristic parameter of UCI to be fed back, a transmission parameter for transmitting a PUCCH.

The transmission parameter includes at least one of the following:

the number of interlaces for transmitting the PUCCH;

the number of orthogonal frequency division multiplex (OFDM) symbols for transmitting the PUCCH;

a spreading factor for transmitting the PUCCH; and

an orthogonal sequence for transmitting the PUCCH.

Particularly, in a case that the PUCCH transmission format based on the interlace structure is scheduled for the terminal device and the PUCCH transmission format can support UCI of more than two bits, at least one of the foregoing information is determined.

The characteristic parameter includes a bit quantity of the UCI, or a bit quantity and a code rate of the UCI.

In this embodiment of the present disclosure, a transmission parameter satisfying a preset condition when the PUCCH is transmitted is determined based on the characteristic parameter of the UCI. The preset condition is: a code rate of uplink information to be transmitted on the PUCCH is lower than or equal to a configured code rate; and the uplink information includes the UCI, or the uplink information includes the UCI and a cyclic redundancy check (CRC). The configured code rate may be configured by a network-side device.

The following describes in detail how to determine the foregoing information.

(1) The determining a transmission parameter satisfying a preset condition for transmitting the PUCCH includes: determining the minimum number of interlaces satisfying the preset condition.

For example, when the UCI is sent, if the number of UCI bits is greater than 2 and less than or equal to 11, an RM (Reed-Muller) coding mode is used for the UCI, there is no need to add a CRC, and a code rate of carried information represents the code rate of the UCI; or if the number of UCI bits is greater than 11, polar coding is used, a CRC bit needs to be added for checking, and a code rate of carried information is a code rate of the UCI plus the CRC.

Specifically, in an actual application, by using radio resource control (RRC) signaling, a base station configures PUCCH resource parameters, including a start interlace index SinterlacePUCCHcorresponding to an allocated interlace, the number NinterlacePUCCHof interlaces, a start OFDM symbol position SsymbolPUCCH, the number NsymbolPUCCHof OFDM symbols, a spreading factor NSFPUCCH, an orthogonal sequence wn, a code rate r, and the like.

In this case, a minimum M satisfying the following inequality can be determined, and the minimum M is used as the number of interlaces for transmitting the PUCCH, where M is a positive integer:

OUCIrepresents a bit quantity of the UCI; OCRCrepresents a bit quantity of the CRC; MPRBPUCCHrepresents the number of PRBs included in M interlaces, that is, the number of PRBs for transmitting the PUCCH; Nsc,ctrlRBrepresents the number of subcarriers for transmitting control information in one PRB, for example, Nsc,ctrlRB=NscRB−4 for an NR R15 PUCCH format 2, Nsc,ctrlRB=NscRBfor a PUCCH format 3, or Nsc,ctrlRB=NscRB/NSFPUCCH,4for a PUCCH format 4; NscRBrepresents the number of subcarriers in one PRB, that is, mapping of Nsc,ctrlRBwith a demodulation reference signal (DMRS) of the PUCCH format, which is related to whether there is a spreading factor; NsymbolPUCCHrepresents the number of OFDM symbols configured by the network-side device; Qmrepresents an order of modulation and coding; r represents the code rate; NinterlacePUCCHrepresents the number of interlaces configured by the network-side device; and NPRBinterlace,jrepresents the number of PRBs included in an interlace whose index is j.

When M=NinterlacePUCCH, if OUCI+OCRC>MPRBPUCCH·Nsc,ctrlRB. NsymbolPUCCH·Qm·r, the number of interlaces for transmitting the PUCCH by the UE is NinterlacePUCCH, that is, the UE uses the number of interlaces configured by using RRC, to transmit the PUCCH.

(2) The determining a transmission parameter satisfying a preset condition for transmitting the PUCCH includes: determining the minimum number of OFDM symbols satisfying the preset condition.

Specifically, in an actual application, a minimum N satisfying the following inequality is determined, and the minimum N is used as the number of OFDM symbols for transmitting the PUCCH, where N is a positive integer:

OUCIrepresents a bit quantity of the UCI; OCRCrepresents a bit quantity of the CRC; MPRBPUCCHrepresents the number of PRBs included in NinterlacePUCCHinterlaces configured by the network-side device, that is, the number of PRBs for transmitting the PUCCH; Nsc,ctrlRBrepresents the number of subcarriers for transmitting control information in one PRB, for example, Nsc,ctrlRB=NscRB−4 for an NR R15 PUCCH format 2, Nsc,ctrlRB=NscRBfor a PUCCH format 3, or Nsc,ctrlRB=NscRB/NSFPUCCH,4for a PUCCH format 4; NscRBrepresents the number of subcarriers in one PRB, that is, mapping of Nsc,ctrlRBwith a DMRS of the PUCCH format which is related to whether there is a spreading factor; Qmrepresents an order of modulation and coding; r represents the code rate; and NsymbolPUCCHrepresents the number of OFDM symbols configured by the network-side device.

When N=NsymbolPUCCHif OUCI+OCRC>MPRBPUCCH·Nsc,ctrlRB·NsymbolPUCCH·Qm·r, the number of OFDM symbols for transmitting the PUCCH by the UE is NsymbolPUCCH, that is, the UE uses the number of OFDM symbols configured by using RRC, to transmit the PUCCH.

(3) The determining a transmission parameter satisfying a preset condition for transmitting the PUCCH includes:

first obtaining a spreading factor set configured by the network-side device, where the spreading factor set may include one or more spreading factors; then determining, from the spreading factor set, a largest spreading factor satisfying the preset condition; and finally using the largest spreading factor as the spreading factor for transmitting the PUCCH.

After the spreading factor is determined in the foregoing manner, an orthogonal sequence corresponding to the largest spreading factor can be used as the orthogonal sequence for transmitting the PUCCH.

Specifically, in an actual application, the largest spreading factor satisfying the following inequality is used as the spreading factor for transmitting the PUCCH:

where Nsc,ctrlRB=NscRB/NSFPUCCH, or Nsc,ctrlRB=NscRB−Nsc,DMSRRB/NSFPUCCH;

OUCIrepresents a bit quantity of the UCI; OCRCrepresents a bit quantity of the cyclic redundancy check CRC; MPRBPUCCHrepresents the number of PRBs included in M interlaces, that is, the number of PRBs for transmitting the PUCCH; Nsc,ctrlRBrepresents the number of subcarriers for transmitting control information in one PRB; NscRBrepresents the number of subcarriers in one PRB; Nsc,DMSRRBrepresents the number of subcarriers for DMRS in one PRB (used only for a PUCCH format in which a DMRS and UCI are frequency division multiplexed; for a PUCCH format in which a DMRS and UCI are time division multiplexed, Nsc,DMSRRB=0); NsymbolPUCCHrepresents the number of OFDM symbols configured by the network-side device; Qmrepresents an order of modulation and coding; r represents the code rate; and NSFPUCCHrepresents a spreading factor configured by the network-side device.

When NSFPUCCHis a smallest spreading factor configured by the network-side device, if OUCI+OCRC>MPRBPUCCH·Nsc,ctrlRB·NsymbolPUCCH·Qm·r/NSFPUCCHstill holds, the spreading factor for transmitting the PUCCH by the UE is a smallest spreading factor configured by the network-side device, that is, the UE uses the smallest spreading factor configured by using RRC, to transmit the PUCCH.

In this embodiment of the present disclosure, the method may be applied to the terminal device, for example, a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device. The method may also be applied to the network-side device, for example, the base station.

In this embodiment of the present disclosure, information required for actually transmitting the PUCCH can be adjusted based on the characteristic parameter of the UCI to be fed back, so that resource utilization is improved.

FIG. 2is a flowchart of an information processing method according to this embodiment of the present disclosure. The method is applied to a terminal device. As shown inFIG. 2, the method includes the following steps.

Step201: In a case that a size of a BWP of the terminal device is larger than that of an LBT subband, obtain first information. The first information is used to indicate at least one of the following information: a resource configuration of a PUCCH and a transmission mode of the PUCCH. The transmission mode includes transmission in only one LBT subband or repeated transmission in different LBT subbands of a target bandwidth part.

In this embodiment of the present disclosure, the target bandwidth part is the BWP of the terminal device, or the target bandwidth part is a subset of the BWP of the terminal device. In addition, the target bandwidth part may be configured by a network-side device, or indicated by a network-side device by using downlink control information (DCI), or determined by the terminal device according to a preset rule.

Step202: Transmit the PUCCH in different LBT subbands in a repetition mode according to the first information.

For example, assuming that the BWP of the terminal device has three LBT subbands, the PUCCH can be repeatedly transmitted in each LBT subband.

In this embodiment of the present disclosure, the first information is preconfigured or dynamically indicated by using higher layer signaling. The first information may include at least one of the following:

the number of interlaces allocated to the PUCCH and information about an LBT subband in which the PUCCH is located;

the number of interlaces allocated to the PUCCH, an index of a start physical resource block (PRB) of the interlace, and the number of PRBs occupied by the interlace;

the number of interlaces allocated to the PUCCH, an index of a start PRB of the interlace, and an index of an end PRB of the interlace; and

whether the PUCCH can be transmitted in more than one LBT subband.

In this embodiment of the present disclosure, when the terminal device works in a large bandwidth, how the PUCCH is transmitted and multiplexed is clear, so that reliability of communication is ensured.

FIG. 3is a flowchart of an information processing method according to this embodiment of the present disclosure. The method is applied to a terminal device. As shown inFIG. 3, the method includes the following steps.

Step301: Perform idle channel detection in a case that time domain resources for a first PUCCH and a second PUCCH overlap, where the first PUCCH corresponds to first UCI and the second PUCCH corresponds to second UCI.

Step302: Determine a transmission mode of the first UCI and the second UCI based on a result of the idle channel detection.

This step includes: determining, based on a multiplexing rule, a multiplex PUCCH after the first UCI and the second UCI are multiplexed; and in a case that the multiplex PUCCH includes the first PUCCH or the second PUCCH, transmitting the first UCI and/or the second UCI based on the result of the idle channel detection, if either of the following conditions is satisfied:

the first PUCCH and the second PUCCH have different start symbols, and the first PUCCH and the second PUCCH are located in different LBT subbands; or in a case that the multiplex PUCCH includes a third PUCCH, transmitting the first UCI and the second UCI based on the result of the idle channel detection, if either of the following conditions is satisfied:

any two or three of the first PUCCH, the second PUCCH, and the third PUCCH have different start symbols, and any two or three of the first PUCCH, the second PUCCH, and the third PUCCH are located in different LBT subbands, where the third PUCCH is a PUCCH other than the first PUCCH and the second PUCCH.

Specifically, the performing idle channel detection includes: performing idle channel detection on the multiplex PUCCH before the multiplex PUCCH is transmitted or in an LBT subband in which the multiplex PUCCH is located; and

the determining a transmission mode of the first UCI and the second UCI includes:

in a case that a result of the idle channel detection before the multiplex PUCCH is transmitted or in the LBT subband in which the multiplex PUCCH is located indicates “idle”, transmitting the first UCI and the second UCI on the multiplexed PUCCH.

In a case that a result of the idle channel detection before the multiplex PUCCH is transmitted or in the LBT subband in which the multiplex PUCCH is located indicates “busy”, idle channel detection is performed before the first PUCCH or the second PUCCH, or in an LBT subband in which the first PUCCH or the second PUCCH is located; and in a case that a result of the idle channel detection before the first PUCCH or the second PUCCH or in the LBT subband the first PUCCH or the second PUCCH is located indicates “idle”, the first UCI or the second UCI is transmitted.

A network-side device performs blind detection. If the first PUCCH is received, the network-side device can determine that the first PUCCH carries the first UCI, or the first UCI and the second UCI; if the second PUCCH is received, the network-side device can determine that the first PUCCH carries the second UCI, or the first UCI and the second UCI; or if the third PUCCH is received, the network-side device can determine that the third PUCCH carries the first UCI and the second UCI.

In this embodiment of the present disclosure, even when channel monitoring finds one PUCCH busy, it is still possible that UCI transmission be performed on other channels, thereby facilitating system access in NRU (NR in Unlicensed Spectrum, NR working in unlicensed spectrum), increasing a possibility of sending uplink control information, and improving effectiveness of system communication.

FIG. 4is a flowchart of an information processing method according to this embodiment of the present disclosure. The method is applied to a network-side device. As shown inFIG. 4, the method includes the following steps.

Step401: In a case that a size of a BWP of a terminal device is larger than that of an LBT subband, send first information to the terminal device.

Step402: Receive a PUCCH transmitted by the terminal device, where the PUCCH is transmitted by the terminal device in different LBT subbands of a target bandwidth part in a repetition mode according to the first information.

The first information is used to indicate at least one of the following information: a resource configuration of the PUCCH and a transmission mode of the PUCCH; and

the target bandwidth part is the BWP of the terminal device, or the target bandwidth part is a subset of the BWP of the terminal device.

On a basis of the foregoing embodiment, to further improve communication efficiency, the method may further include:

configuring the target bandwidth part, or indicating the target bandwidth part to the terminal device by using DCI.

The first information includes any one of the following:

the number of interlaces allocated to the PUCCH and information about an LBT subband in which the PUCCH is located;

the number of interlaces allocated to the PUCCH, an index of a start physical resource block PRB of the interlace, and the number of PRBs occupied by the interlace;

the number of interlaces allocated to the PUCCH, an index of a start physical resource block PRB of the interlace, and an index of an end PRB of the interlace; and

whether the PUCCH can be transmitted in more than one LBT subband.

In this embodiment of the present disclosure, when the terminal device works in a large bandwidth, how the PUCCH is transmitted and multiplexed is clear, so that reliability of communication is ensured.

An embodiment of the present disclosure provides a PUCCH information processing method in a case of an NR unlicensed band. The method mainly includes: when a PUCCH transmission format based on an interlace structure is scheduled for UE and the corresponding PUCCH transmission format is capable of supporting UCI of more than two bits, the UE determines at least one of the following based on a bit quantity and a code rate of UCI to be fed back:

(1) the UE determines, based on the bit quantity and code rate of current UCI to be fed back, the number of interlaces actually used for transmitting a PUCCH;

(2) the UE determines, based on the bit quantity and code rate of current UCI to be fed back, the number of OFDM symbols actually used for transmitting a PUCCH;

(3) the UE determines, based on the bit quantity and code rate of current UCI to be fed back, a spreading factor actually used for transmitting a PUCCH, and may further determine an orthogonal sequence.

If a bandwidth of a current BWP of the UE is larger than 20 MHz (the bandwidth is an integer multiple of 20 MHz, that is, N×20 MHz), for PUCCH transmission based on an interlaced resource block structure:

PUCCH resource configuration mode: a base station indicates an interlace allocated to the PUCCH and an LBT subband in which the PUCCH is located, or an interlace allocated to the PUCCH (which may include a start interlace index and the number of interlaces), a start PRB index corresponding to the interlace, and the number of occupied PRBs (or a start PRB index and an end PRB index). If PUCCH transmission based on the interlaced resource block structure is scheduled for the UE, the UE transmits the PUCCH in N bandwidths of 20 MHz in a repetition mode based on the indication or configuration of the base station.

If time domain resources for two PUCCHs overlap, the UE performs transmission based on an LBT result:

(a) If time domain resources for two PUCCHs overlap, and are located in different LBT subbands, the UE multiplexes UCI on one channel based on an LBT result, or transmits one of the channels and information.

(b) If time domain resources for two PUCCHs overlap, and have different start symbols, the UE multiplexes UCI on one channel based on an LBT result, or transmits one of the channels and information.

Particularly, the UE performs LBT before the PUCCH on which the UCI is multiplexed is transmitted or in the LBT subband in which the PUCCH is located. If it is detected that the channel is idle, the UE transmits the multiplexed UCI on the multiplexed PUCCH. If the UE performs LBT before transmitting the PUCCH on which the UCI is multiplexed or in the LBT subband in which the multiplex PUCCH is located and detects that the channel is busy, and the UE performs LBT before another PUCCH is transmitted or in the LBT subband in which the another PUCCH is located and detects that the channel is idle, the UE transmits the another PUCCH and UCI carried in the another PUCCH.

The following describes implementation processes of the embodiments of the present disclosure in detail with reference to specific embodiments.

In an embodiment of the present disclosure, by using RRC signaling, the base station configures PUCCH resource parameters, including a start interlace index SinterlacePUCCHcorresponding to an allocated interlace, the number NinterlacePUCCHof interlaces, a start OFDM symbol position SsymbolPUCCH, the number NsymbolPUCCHof OFDM symbols, a spreading factor NSFPUCCH, an orthogonal sequence wn, a code rate r, and the like.

For example, the UE adjusts, based on the bit quantity and code rate of UCI to be sent, the number of interlaces of the PUCCH during transmission:

If the number of interlaces allocated to the PUCCH is greater than 1, the UE may adjust, based on the bit quantity and code rate of UCI to be fed back, interlaces used during actual transmission, where OUCI+OCRC≤MPRBPUCCH·Nsc,ctrl·NsymbolPUCCH·Qm·r, where MPRBPUCCH=Σj=SinterfacePUCCHSinterlacePUCCHMNPRBinterlace,j, M≤NinterlacePUCCH. In this case, the number of interlaces actually used by the UE for transmission is M, and indexes are SinterlacePUCCHto SinterlacePUCCH+M.

For example, the UE adjusts, based on the bit quantity and code rate of UCI to be sent, the number of OFDM symbols of the PUCCH during transmission:

If the number of interlaces allocated to the PUCCH is greater than 1, the UE may adjust, based on the bit quantity and code rate of UCI to be fed back, the number of OFDM symbols used during actual transmission, where OUCI+OCRC≤MPRBPUCCH·Nsc, ctrlRB·N·Qm·r, where N≤NsymbolPUCCH. In this case, the number of PUCCH symbols used by the UE for transmission is N, and indexes are SsymbolPUCCHto SsymbolPUCCH+N.

For example, the UE adjusts, based on the bit quantity and code rate of UCI to be sent, a spreading factor (and an orthogonal sequence) used for the PUCCH during transmission:

The base station configures different spreading factors for each PUCCH, for example, NSF,1PUCCH=2 and NSF,2PUCCH=4, and each spreading factor corresponds to an orthogonal sequence wn,1or wn,2.

If the number of interlaces allocated to the PUCCH is greater than 1, the UE may adjust interlaces during actual transmission, based on the bit quantity and code rate of UCI to be fed back, where OUCI+OCRC≤MPRBPUCCH·NscRB·NsymbolPUCCH·Qm·r/NSFPUCCH. For a spreading factor, the UE tries from a largest spreading factor, and then a second largest spreading factor, until a largest spreading factor that satisfies the foregoing inequality.

To be specific, if NSFPUCCH=NSF,2PUCCH=4, which satisfies the foregoing inequality, the spreading factor used by the UE for transmission is NSFPUCCH=NSF,2PUCCH, and the orthogonal sequence is wn,2; otherwise, the spreading factor used by the UE for transmission is NSFPUCCH=NSF,1PUCCH, and the orthogonal sequence is wn,1.

As shown inFIG. 5(a)andFIG. 5(b), a UL BWP bandwidth activated by the UE is 80 MHz. For transmission of the PUCCH based on the interlace structure, because generally only a few PRBs are required by the PUCCH, transmission of the PUCCH is usually performed in a 20 MHz bandwidth. PUCCH transmission designs, including a transmission sequence, an orthogonal sequence, rate matching, and the like, are all in one or more interlaces within 20 MHz. However, if the BWP bandwidth configured for the UE is wideband transmission, in some cases, transmitting the PUCCH in the entire BWP helps the UE preempt a channel and avoid unnecessary LBT. For example, as shown inFIG. 5(c), two PUSCHs are scheduled for the UE, and each PUSCH occupies an 80 MHz bandwidth, but the two PUSCHs are not continuous in time domain, and a PUCCH is scheduled between the PUSCHs. If the PUCCH channel bandwidth is 20 MHz, in other 60 MHz without the PUCCH, because there is a gap between the two PUSCHs, a channel resource may be preempted by another access point before a PUSCH2is transmitted, and consequently the PUSCH2cannot be transmitted. In this case, the UE may transmit the PUCCH in the entire BWP based on an instruction of the base station. To simplify the PUCCH design, the UE repeats the PUCCH transmitted in 20 MHz in different LBT subbands in a repetition mode.

As shown inFIG. 6(a)andFIG. 6(b), a PUCCH1is a channel state information (CSI) PUCCH, and a PUCCH2is a scheduling request (SR) PUCCH. The two PUCCHs are located in a same LBT subband, but have different start symbols. Based on a UCI multiplexing rule, when time domain resources for the CSI PUCCH and the SR PUCCH overlap, the UE multiplexes an SR on the CSI PUCCH, that is, the SR is transmitted on the PUCCH1. The UE performs LBT before the PUCCH1is transmitted; and if detecting that the channel is idle, sends the PUCCH1; or if detecting that the channel is busy, cannot transmit the PUCCH1.

According to this embodiment of the present disclosure, for example, inFIG. 6 (a), if the UE detects, before the PUCCH1is transmitted, that the channel is idle, the UE transmits the CSI and the SR on the PUCCH1; if detecting that the channel is busy, the UE cannot transmit the PUCCH1; if the SR is positive, the UE may continue to perform LBT before the PUCCH2; if the UE detects that the channel is idle in this case, the UE transmits the positive SR (the UE does not transmit the CSI) through the PUCCH2.

InFIG. 6(b), the PUCCH1and the PUCCH2are located in different subbands. Therefore, the UE may perform LBT in different LBT subbands separately. If detecting, in the LBT subband in which the PUCCH1is located, that the channel is idle, the UE transmits the CSI and the SR on the PUCCH1; if the subband in which the PUCCH1is located is busy, and the subband in which the PUCCH2is located is idle, the UE transmits the positive SR (without transmitting the CSI) through the PUCCH2.

InFIG. 6(a)orFIG. 6(b), if the PUCCH1is a CSI PUCCH, the PUCCH2is an SPS hybrid automatic repeat request acknowledgement (HARQ-ACK) PUCCH. Based on the UCI multiplexing rule, a HARQ-ACK is multiplexed on the CSI PUCCH for transmission. If the UE detects, before the PUCCH1or in the LBT subband in which the PUCCH1is located, that the channel is idle, the UE transmits the CSI and the HARQ-ACK on the PUCCH1; if the UE detects, before the PUCCH1or in the LBT subband in which the PUCCH1is located, that the channel is busy, and the UE detects, before the PUCCH2or in the LBT subband in which the PUCCH2is located, that the channel is idle, the UE transmits the HARQ-ACK (the UE does not transmit the CSI) on the PUCCH2.

As shown inFIG. 6(c), the PUCCH1is a PUCCH carrying a HARQ-ACK corresponding to a physical downlink shared channel (PDSCH) dynamically scheduled by a PDCCH, and the PUCCH2is a CSI PUCCH. A PUCCH3is a PUCCH for multiplexing the HARQ-ACK and the CSI and determined based on a rule for multiplexing the HARQ-ACK and the CSI. As shown in the figure, if the UE detects, before the PUCCH3is transmitted, that the channel is idle, the UE transmits the PUCCH3(carrying the HARQ-ACK and the CSI); if detecting that the channel is busy, the UE may continue to perform LBT before the PUCCH2; if detecting, before the PUCCH2is transmitted, that the channel is idle, the UE may transmit the PUCCH2(carrying the CSI); if detecting that the channel is busy, the UE may continue to perform LBT before the PUCCH1; if detecting, before the PUCCH1is transmitted, that the channel is idle, the UE may transmit the PUCCH1(carrying the HARQ-ACK).

In the foregoing embodiment, optionally, the UE detects a channel idle state before the multiplex PUCCH is transmitted or in the LBT subband in which the multiplex PUCCH is located. If it is detected that the channel is idle, the multiplex PUCCH and multiplexed UCI of the multiplex PUCCH are transmitted; if it is detected that the channel is busy, and if the first PUCCH or the second PUCCH and the multiplex PUCCH are located in different subbands, or a start symbol of the first PUCCH or the second PUCCH is later than a start symbol of the multiplexed PUCCH, the UE may perform idle channel detection in the subband in which the first PUCCH or the second PUCCH is located or before the first PUCCH or the second PUCCH is transmitted; if detecting that the channel is idle, the UE transmits the first PUCCH and the UCI of the first PUCCH, or the second PUCCH and the UCI of the second PUCCH.

In another implementation of this embodiment of the present disclosure, if the multiplexed PUCCH, the first PUCCH, and the second PUCCH have different start symbols, the UE performs, before the PUCCHs are transmitted, idle channel detection in a chronological order of the start symbols corresponding to the PUCCHs. If it is detected that the channel is idle before a PUCCH having an earliest start symbol is transmitted, the corresponding PUCCH and its UCI are transmitted; if it is detected that the channel is busy, idle channel detection is performed before a PUCCH after the PUCCH having the earliest start symbol; if it is detected that the channel is idle, the corresponding PUCCH and its UCI are transmitted, and so on, until a PUCCH having a latest start symbol.
