Abstract: Methods and apparatuses are provided for monitoring a physical downlink control channel (PDCCH) in a wireless communication system. A UE receives a system information block (SIB) from a base station. The UE obtains a first time division duplex (TDD) uplink (UL)/downlink (DL) configuration from the SIB. The UE identifies DL subframes in a radio frame. The UE monitors the PDCCH transmitted from the base station on a DL subframe included in an on duration period of a discontinuous reception (DRX) cycle. The UE obtains information about a second TDD UL/DL configuration from the monitored PDCCH. The UE applies the second TDD UL/DL configuration to the radio frame. The DL subframe corresponds to a predetermined subframe number in the radio frame. The on duration period represents a period corresponding to a predetermined number of subframes from a subframe where the DRX cycle starts, and the on duration period is repeated periodically.

Abstract: A method and system for minimizing the battery power consumption of user equipment (UE) during inter-frequency cell detection in a heterogeneous network is disclosed. A serving cell in the heterogeneous network provides a relaxed cell detection indication to the UE on a specified frequency for cell detection. The UE applies the relaxed cell detection for detecting the cells on the specified frequency. During inter-frequency cell detection on specified frequency, the UE discards some normal measurement gaps. The inter-frequency cell detection is delayed as compared to normal cell detection time requirement using the normal measurement gaps. The UE deactivates the relaxed detection indication, upon detecting the inter-frequency cell and performs the continuous RSRP and RSRQ measurements for detected inter-frequency cell using all the normal measurement gaps to meet normal measurement accuracy and measurement reporting requirement.
