Abstract

An embodiment of the present invention provides a physical uplink control channel transmission method, a terminal, and a network-side device. The method includes: transmitting on the first physical uplink control channel PUCCH resource corresponding to a network-side device when performing separate feedback of uplink control information UCI The UCI information of the network-side device; when UCI joint feedback is performed, the UCI information of the at least two network-side devices is transmitted on the second PUCCH resource; wherein, the first PUCCH resource and the second PUCCH resource are located at on different resource groups. The present invention realizes the UCI feedback of each network side device on the PUCCH resource. In this way, the problem of PUCCH resource conflict caused when only UCI is used for individual feedback can be solved, and at the same time, the problem of low utilization of PUCCH resources caused by only UCI combined feedback can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a physical uplink control channel transmission method, network side equipment and terminal. Background technique [0002] As we all know, in 3GPP Rel-15, the multi-TRP / multi-panel scenario was proposed, and the transmission and receiving point (TRP) transmission can increase the transmission reliability and Throughput performance, for example, a terminal (User Equipment, UE) can receive the same data or different data from multiple TRPs. Currently, the Type I multi-antenna panel codebook is defined, and several multi-TRP transmission scenarios are initially discussed: [0003] 1) Multi-TRP / panel transmission between multiple TRPs, ideal backhaul (backhaul); [0004] 2) Multi-TRP / panel transmission between multiple TRPs is not an ideal backhaul line. [0005] Among them, the transmission scheme of multiple TRPs may be: [0006] Multiple TRPs send multiple Physic...
