The UE receives a system information block (SIB) from a base station. The UE identifies downlink (DL) subframes indicated by a first time division duplex (TDD) uplink (UL)/DL configuration in the SIB. The UE monitors the PDCCH transmitted from the base station on at least one DL subframe included in an active time of a discontinuous reception (DRX) cycle among the DL subframes. The UE obtains information about a second TDD UL/DL configuration from the monitored PDCCH. The UE monitors the PDCCH using the second TDD UL/DL configuration. The active time includes a duration corresponding to a number of at least one consecutive DL subframe at a beginning of the DRX cycle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for determining TDD UL-DL configuration applicable for radio frames","description":"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.
