Problems solved by technology

[0011] Question 1: In uplink multiplexing of R15, the judgment of the processing timeline does not apply to intra-UE multiplexing scenarios, such as figure 1 As shown, the processing time of URLLC HARQ-ACK will be shorter than that of eMBB HARQ-ACK. If the rules of R15 are followed, it will be judged that the processing timeline is not satisfied, which is an error situation;
[0012] Question 2: URLLC's HARQ-ACK has higher latency and reliability requirements than eMBB's HARQ-ACK, such as figure 2 As shown, according to the rules of R15, after URLLC HARQ-ACK and eMBB HARQ-ACK are multiplexed, the delay and reliability requirements of URLLC HARQ-ACK may not be met

Abstract

The embodiment of the invention provides an uplink channel multiplexing method and device, and a terminal, and the method comprises the following step that when the terminal needs to transmit a plurality of overlapped physical uplink control channels (PUCCH) and/or physical uplink shared channels (PUSCH) in the same time slot or sub-time slot, if one of the PUCCH transmission or the PUSCH transmission corresponds to a downlink control information (DCI) format detected by the terminal, the terminal expects that a start symbol S0 of the earliest PUCCH or PUSCH in the overlapped PUCCHs and/or PUSCHs meets a first condition. According to the scheme of the invention, the error condition and the processing condition that the base station cannot control the terminal can be avoided, the time delay and reliability requirements of the URLLC service are met, and the system spectrum efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and terminal for multiplexing an uplink channel. Background technique [0002] In R15, the multiplexing mechanism of PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) and PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) includes: [0003] 1. Judgment of the processing timeline: that is, among all overlapping PUCCH(s) and PUSCH(s), find the earliest PUCCH or PUSCH, and its first symbol S0 needs to guarantee the physical downlink shared channel PDSCH (if Yes) to be processed, SPS (Semi-Persistent Scheduling, semi-persistent scheduling) release (if any) to be processed, PUSCH (if any) to be processed, CSI (Channel State Information, channel state information) report (if any) It must be processed; if the processing timeline is not met, it will be judged as an error situation; [0004] 2. Construct a PUCCH ...
