Title:
METHOD AND DEVICE FOR INDICATING CONTROL CHANNEL
Document Type and Number:
WIPO Patent Application WO/2019/214671
Kind Code:
A1
Abstract:
Provided by the present application are a method and device for indicating a control channel, the method comprising: a network device sends, to a terminal device, information for indicating N control resource sets (CORESET) and M transmission configuration indicator states (TCI states) corresponding to each CORESET respectively, wherein the M TCI states are in one-to-one association with M search space groups, each of the search space groups comprises one or more search spaces, the CORESET and the search spaces are used by the terminal device to determine transmission resources of a control channel, and the TCI states are used by the terminal device to determine quasi co-location (QCL) information of the control channel, N being an integer greater than or equal to 1, and M being an integer greater than or equal to 2. The flexibility of resource scheduling may thus be effectively improved by configuring CORESETs corresponding to multiple TCI states.
