Abstract

The embodiment of the present invention discloses a wireless communication method and device. The method includes: receiving association relationship indication information; determining that a plurality of first CORESETs have an association relationship according to the association relationship indication information, and the plurality of first CORESETs Share the first shared quasi-co-location QCL information. The method in the embodiment of the present invention does not need to configure QCL information for each CORESET, and can reduce signaling overhead.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically relates to a method and device for wireless communication. Background technique [0002] In the current mobile communication system, for the beam indication of the physical downlink control channel (Physical Downlink ControlChannel, PDCCH), the network device uses radio resource control (Radio Resource Control, RRC) signaling for each control resource set (Control Resource Set, CORESET ) to configure K transmission configuration indication (Transmission Configuration Indication, TCI) states (state), when K>1, a TCI state is indicated by a Media Access Control Control Element (MAC CE), when K=1 , no additional MAC CE commands are required. When the terminal device monitors the CORESET, it uses the same quasi-colocation (QCL) information, that is, the same TCI state, for all search spaces (Search Space) inside the CORESET. The terminal device can learn the...
