Patent ID: 11172534

Abstract:
A method and an apparatus are provided for monitoring a physical downlink control channel (PDCCH) by a user equipment (UE) in a wireless communication system. The UE receives a system information block (SIB) from a network. The UE identifies at least one downlink (DL) period based on a first time division duplex (TDD) uplink (UL)/DL configuration included in the SIB; monitoring, by the UE, the PDCCH during the at least one DL period using a discontinuous reception (DRX) operation. The UE obtains information about at least one second TDD UL/DL configuration for one or more time intervals from the monitored PDCCH. The monitoring of the PDCCH comprises monitoring the PDCCH in an active time of a DRX cycle. The active time includes a time when the UE performs continuous reception.
