Abstract

The invention discloses a channel transmission method, a terminal and network equipment. The method comprises the following steps: acquiring target transmission configuration indication (TCI) state information of a control resource set CORESET0 with an identification value of 0; when a preset condition is satisfied, receiving a physical downlink channel according to the target TCI state information; wherein the physical downlink channel comprises at least one of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH). According to the network equipment and the terminal provided by the embodiment of the invention, when the preset condition is met, the physical downlink channel is transmitted according to the TCI state information of the CORESET0, so that the transmission flexibility of the physical downlink channel can be improved, and the system performance is further improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a channel transmission method, terminal and network equipment. Background technique [0002] In a mobile communication system, for a Physical Downlink Control Channel (PDCCH), a terminal will receive a PDCCH common search space (common search space) and various parameters configured by a network device, wherein the transmission control indicator (Transmission Control indicator , the TCI) state (state) parameter includes multiple TCI states of the PDCCH, and the network device can activate one of the TCI states through the medium access medium (Medium Access Control, MAC) layer control element (Control Element, CE), the terminal assumes that the above PDCCH The demodulation reference signal (De-Modulation Reference Signal, DMRS) port and the synchronization signal block (Synchronization Signal and PBCH Block, SSB) of the initial access configuration are quasi co-loca...
