Description

Information transmission method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information transmission method and apparatus.

Background

In the NR system, NR Physical Uplink Control Channel (PUCCH) formats (formats) 0, 1, 2, 3, 4 are defined to be 5 PUCCH formats, where the PUCCH formats of formats 0 and 1 may carry 1-2 bit UCI transmission, and the PUCCH formats 2, 3, and 4 may carry more than 2 bit UCI transmission. A hybrid automatic repeat request acknowledgement (HARQ-ACK) may use any one of the 5 PUCCH formats. And the terminal selects one of a plurality of PUCCH resource sets which are configured to the terminal in advance according to the bit number of the HARQ-ACK, wherein each PUCCH resource set corresponds to a bit number range. Scheduling Request (SR) may be transmitted using PUCCH format 0 or 1, and the used PUCCH resource is configured by higher layer signaling. Periodic Channel State Information (CSI) may be configured to be transmitted using PUCCH format 2 or 3 or 4, and the PUCCH resource used is configured by higher layer signaling.

In an NR release 15(R15) system, when a PUCCH carrying CSI/SR and a PUCCH carrying HARQ-ACK are overlapped in resources, multiplexing transmission is carried out according to the following method:

when the PUCCH bearing the SR is overlapped with the PUCCH format 0 bearing the HARQ-ACK, the SR and the HARQ-ACK are transmitted through PUCCH resource multiplexing of the HARQ-ACK;

when PUCCH format 0 bearing SR is overlapped with PUCCH format 1 bearing HARQ-ACK, the SR is discarded;

when PUCCH format 1 bearing SR is overlapped with PUCCH format 1 bearing HARQ-ACK, HARQ-ACK is transmitted on PUCCH resource of SR in positive SR, and HARQ-ACK is transmitted on PUCCH resource of HARQ-ACK in negative SR;

when the PUCCH carrying SR overlaps PUCCH format 2/3/4 carrying HARQ-ACK, both SR (including positive and negative SR) and HARQ-ACK are put on HARQ-ACK resources for transmission;

when the PUCCH carrying SPS HARQ-ACK (namely HARQ-ACK corresponding to SPS PDSCH) is overlapped with the PUCCH carrying CSI, the SPS HARQ-ACK is transferred to PUCCH resources corresponding to the CSI for multiplexing transmission with the CSI. When a PUCCH carrying dynamic (dynamic) HARQ-ACK (namely the HARQ-ACK corresponding to the PDSCH with the corresponding DCI scheduling) is overlapped with a PUCCH carrying CSI, one set is selected from the configured PUCCH resource sets according to the bit numbers of the HARQ-ACK and the CSI, and one PUCCH resource is determined from the selected set according to a PUCCH resource indication domain in the DCI for scheduling the PDSCH and is used for carrying the HARQ-ACK and the CSI simultaneously.

In summary, in the prior art, there is only one overlapping PUCCH resource for HARQ-ACK and PUCCH resource for CSI/SR, and there is no overlapping PUCCH resource for carrying HARQ-ACK and PUCCH resource for carrying SR/CSI in multiple time-division multiplexing, and multiple time-division multiplexing PUCCH resources for carrying HARQ-ACK are supported to be transmitted in one slot in Rel-16, so when multiple PUCCH resources for carrying HARQ-ACK and PUCCH resources for carrying SR/CSI overlap, there is no solution at present.

In the technical solution provided in the embodiment of the present application, when multiple time-division multiplexed PUCCH for carrying HARQ-ACK and PUCCH resources for carrying CSI or SR are overlapped, Uplink Control Information (UCI) that all channels where resource overlapping occurs need to be carried is multiplexed on a finally determined PUCCH (may be a PUCCH for carrying CSI/SR or a PUCCH for carrying HARQ-ACK) resource for transmission. Wherein the plurality of PUCCHs carrying HARQ-ACK are time division multiplexed, namely a plurality of PUCCHs, each PUCCH carries HARQ-ACK, and the PUCCHs are time division multiplexed.

optionally, the multiplexing the UCI information carried by the channels with all resources overlapped on one PUCCH resource (i.e., the finally determined PUCCH resource) is performed for transmission, specifically including;

if at least one dynamic HARQ-ACK (namely the HARQ-ACK corresponding to the dynamic PDSCH transmission) is contained in the plurality of time division multiplexed HARQ-ACKs, the finally determined PUCCH resource is a PUCCH resource for bearing the HARQ-ACK;

if a plurality of time-division multiplexed HARQ-ACKs all use SPS HARQ-ACK (namely HARQ-ACK corresponding to SPS PDSCH transmission) or a plurality of time-division multiplexed PUCCHs carrying the HARQ-ACK all use PUCCH format 0/1, the finally determined PUCCH resources are PUCCH resources used for carrying CSI/SR;

if the finally determined PUCCH resource is a PUCCH resource of HARQ-ACK/CSI, all the UCI information carried by the channels with overlapped resources is cascaded according to the following sequence (the cascade is that a plurality of information bits are connected together according to a specified sequence to generate a long bit sequence):

a plurality of time division multiplexing HARQ-ACKs are cascaded according to the time sequence of the corresponding PUCCH;

if the SR exists, the SR is placed behind the HARQ-ACK information for cascade connection;

if the first part (part 1) of the CSI exists, the CSI part 1 information is placed after the HARQ-ACK/SR information for cascade connection;

if the second part (part 2) of the CSI exists, the CSI part 2 and other UCI information (information except for the CSI part 2 in the UCI information carried by all the overlapping channels) are independently encoded (different information is encoded respectively, and the joint encoding corresponds to the joint encoding, where the joint encoding refers to encoding together after different information is concatenated);

if the finally determined PUCCH resource is SR PUCCH resource and format 1 is used, then:

specifically, the combining manner may be based on combining of codewords, for example, combining feedback information of the same codeword transmitted in different time slots;

or, the combining manner may be based on combining of HARQ-ACK codebooks, for example, combining each HARQ-ACK codebook information (applicable to only 2 TDM HARQ-ACK PUCCHs);

or, the HARQ-ACK information is modulated into one Modulation symbol by a high-order Modulation scheme, and is mapped on the PUCCH resource of the SR for transmission, where the Modulation scheme is BPSK, QPSK, 8PSK (8Phase Shift Keying), 16PSK (16Phase Shift Keying), 16 Quadrature Amplitude Modulation (QAM), 64QAM, 256QAM, 512QAM, or the like.

When the finally determined PUCCH resource is a PUCCH resource carrying HARQ-ACK, the determination is specifically performed in the following manner:

selecting a corresponding PUCCH resource set according to the total number of UCI information bits carried by all the overlapped channels;

determining a PUCCH Resource for multiplexing transmission according to a PUCCH Resource Indication (PRI) information field contained in the last DCI corresponding to HARQ-ACK carried by the plurality of time-division multiplexed PUCCHs carrying HARQ-ACK in the PUCCH Resource set; or

And determining the PUCCH resources for multiplexing transmission in the PUCCH resource set according to the PRI information field contained in the last DCI corresponding to the HARQ-ACK carried by the last PUCCH in the plurality of PUCCHs carrying HARQ-ACK and time division multiplexing.
