Abstract

The embodiment of the invention provides a method and a device for determining a transmission configuration indication state. The method comprises the following steps: receiving high-level configuration information; n control resource sets (CORESETs) and at least one transmission configuration indication state (TCI) state corresponding to each CORESET are determined on the basis of the high-level configuration information; a target CORESET is determined in the N pieces of CORESET; and determining a target TCI state in the at least one TCI state corresponding to the target CORESET. By adopting the embodiment of the invention, the problem that the terminal equipment cannot determine at least one of a beam adopted by a transmission channel, a beam adopted by a transmission reference signal, a PL-RS of the transmission channel, a PL-RS of the transmission reference signal, a QCL hypothesis of the transmission channel and a QCL hypothesis of the transmission reference signal through a plurality of TCI states corresponding to the CORESET can be solved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and apparatus for determining the status of a transmission configuration indication. Background technique [0002] In the current New Radio (New Radio, NR) technology, a terminal device can determine a control resource set (Control Resource set, CORESET) based on high-level signaling sent by a network device to determine a unique TCI state, and pass the unique TCI state Determine at least one of the beam used for the transmission channel, the beam used for the transmission reference signal, the path loss reference signal (Path Loss Reference Signal, PL-RS) used to calculate the path loss, and the assumption of QCL (Quasi co-location) . [0003] However, in the transmission scenario of multiple TRPs (transmission and reception points) of 3GPP R17, the terminal device can obtain multiple CORESETs through high-level information, and each CORESET can...
