Patent ID: 11516813

Abstract:
A method and apparatus for transmitting a Transmission Configuration Indicator (TCI), a method and apparatus for receiving a TCI, a storage medium, a base station and a terminal are provided. The method for transmitting a TCI includes: determining a target reference signal, and port groups corresponding to a resource occupied by the target reference signal, wherein large-scale parameters of ports in different port groups are different, for each of the port groups, determining a source reference signal quasi-co-located with the port group, and at least one Quasi-Co-Location (QCL) type of QCLs of the port groups with the source reference signal, to acquire an extended TCI state; and transmitting the extended TCI state and the target reference signal to a UE, so that the UE determines large-scale parameters of the ports for the target reference signal. TCI configuration of multi-panel, multi-Transmission Reference Point (TRP) and multi-beam communication is supported.
