US 10,805,872 B2 · Method and apparatus for configuring control channel according to BWP or beam switching in wireless communication system

Abstract

According to one embodiment of the present disclosure, a method and an apparatus for allowing a user equipment (UE) to effectively monitor a control resource set (CORESET) in order to read remaining minimum system information (RMSI) in a wireless communication system are provided. The UE receives a media access control (MAC) control element (CE) indication, performs a random access channel (RACH) procedure, determines a transmission configuration indicator (TCI) state of CORESET 0 on the basis of the most recent of either the MAC CE indication or the RACH procedure, and monitors CORESET 0 on the basis of the determined TCI state.

Dependent claims

A method performed by a wireless device in a wireless communication system, the method comprising:

receiving a Media Access Control (MAC) Control Element (CE) indication;
performing a Random Access Channel (RACH) procedure;
determining a Transmission Configuration Indicator (TCI) state of Control Resource Set (CORESET) 0based on most recent of the MAC CE indication or the RACH procedure;
and
monitoring the CORESET 0based on the determined TCI state,
wherein a monitoring occasion of search space #0 within the CORESET 0is based on an index of a synchronization signal (SS)/physical broadcast channel (PBCH) block corresponding to the determined TCI state.
