Problems solved by technology

[0005]However, when the uplink channels overlap, there may be some channels in the overlapping uplink channels because there are unavailable symbols in the symbol set occupied by them, so this channel cannot be transmitted , there is no clear plan on how to carry out uplink channel transmission at this time

Embodiment 1

[0132] Embodiment 1: There is a PUCCH and a PUSCH transmission on CC1 (Component Carrier, carrier unit) and CC2 respectively, and the PUCCH and PUSCH overlap in the time domain, wherein, the HARQ-ACK of the SPS PDSCH is carried on the PUCCH (SPS for short) HARQ-ACK), PUSCH does not have a corresponding PDCCH (that is, CG PUSCH), then:

[0133] If the terminal and the base station agree to use the above method 1, it is assumed that the DL symbols configured by high-level signaling, the symbols for downlink transmission scheduled by DCI, the indication information in the DCI used to indicate the time unit structure indicate DL or FL symbols, and SSB The symbols occupied by the transmission are all unavailable symbols, then: on the terminal side, first determine that the HARQ-ACK on the PUCCH is transferred to the PUSCH for transmission according to the multiplexing transmission rule of PUCCH and PUSCH overlap, so that the PUCCH is not transmitted, and the final transmission is ob...

Embodiment 2

[0136] Embodiment 2: There is a PUCCH and a PUSCH transmission on CC1, CC2 and CC3 respectively, and the PUCCH and the two PUSCHs overlap in the time domain, wherein the PUCCH carries SPS HARQ-ACK, and both PUSCHs are CG PUSCH, then:

[0137] If the terminal and the base station agree to use the first method above, it is assumed that the DL symbols configured by high-layer signaling, the symbols for downlink transmission scheduled by DCI, the symbols indicated as DL or FL by DCI format 2-0, and the symbols occupied by SSB transmission are all unavailable. If the symbol is used, then: on the terminal side, first determine that the HARQ-ACK on the PUCCH is transferred to one PUSCH for transmission according to the multiplexing transmission rule of PUCCH and PUSCH overlap, so that the PUCCH is not transmitted. Since there are two PUSCHs overlapping with the PUCCH, it is necessary to Select a PUSCH, according to the selection rules in the prior art (selection order from first to l...

Embodiment 3

[0142] Embodiment 3: There is a PUCCH carrying HARQ-ACK and a PUCCH carrying CSI on CC1, there is overlap between the two PUCCHs, and the HARQ-ACK is the feedback information of the PDSCH with the corresponding PDCCH, then:

[0143] If the terminal and the base station agree to use the above method 1: Assume that the DL symbols configured by high-level signaling, the symbols for downlink transmission scheduled by DCI, the indication information in the DCI used to indicate the time unit structure indicate DL or FL symbols, and SSB If the symbols occupied by transmission are all unavailable symbols, then: on the terminal side, first determine a PUCCH resource for simultaneous transmission of HARQ-ACK and CSI according to the multiplexing transmission rule of PUCCH overlap, specifically according to the total number of HARQ-ACK and CSI The number of bits, select one of the pre-configured multiple PUCCH resource sets, and in the selected PUCCH resource set, determine a PUCCH resour...

Abstract

Provided in an embodiment of the present invention are an uplink channel transmission method, a terminal and a base station. When a plurality of uplink channels overlap in a time domain, the method applied to the terminal comprises the steps: processing the plurality of uplink channels based on a channel multiplexing transmission rule, determining a first target uplink channel to be transmitted, and determining whether to transmit the first target uplink channel or not; determining a candidate uplink channel capable of transmission from the plurality of uplink channels, processing the candidate uplink channel based on a channel multiplexing transmission rule, and determining a second target uplink channel to be transmitted. The embodiment of the invention ensures the normal transmission of the system.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an uplink channel transmission method, a terminal and a base station. Background technique [0002] In 5G New Radio (NR), simultaneous transmission of Physical Uplink Control Channel (PUCCH) and Physical Uplink Shared Channel (PUSCH) (time domain resource overlap) is not supported, nor is it supported Multiple overlapping PUCCHs are simultaneously transmitted on the same carrier. The PUCCH is used to carry uplink control information (Uplink Control Information, UCI), and UCI may include a Hybrid Automatic Repeat request-Acknowledge character (HARQ-ACK), channel state information (Channel State Information, CSI) and One or more combinations of scheduling requests (SchedulingRequest, SR). [0003] When all or part of the symbols of the PUCCH and the PUSCH overlap, it is necessary to determine whether the first symbol of the earliest channel among the PUCCH and t...
