Title:
TRANSMISSION MODE INDICATION METHOD AND DEVICE, BASE STATION, TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/063044
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention are a transmission mode indication method and device, a base station, a terminal and a storage medium. Said method comprises: sending signaling to a terminal UE, so that the UE determines a transmission mode between the UE and a base station according to the signaling, the signaling carrying indication information about a transmission configuration indication (TCI) state, indication information about a redundancy version (RV), indication information about a demodulation reference signal (DMRS) port, and indication information about whether to carry the number of repeated sending times; or, besides the described indication information, the signaling also carrying indication information about a transmission mode. In the embodiments of the present invention, indication information is carried in signaling and is used for indicating a specific transmission mode, so that dynamic switching between different transmission modes can be realized, and the system performance, the reliability and the resource utilization rate are better improved.
