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 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.

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.

Abstract: A method and system to deliver updated system information to one or more victim User Equipments (UEs) in connected mode within the dominant co-channel interference region in Heterogeneous Network (HetNet) environment is disclosed. The method enables the base station of a victim cell to trigger one or more victim UEs in the region of co-channel interference to apply a new signaling procedure for acquiring a new message block to be delivered by the victim cell. The method provides an error handling procedure for system information acquisition failure by the victim UE in the dominant co-channel interference region of the victim cell in HetNet. The method improves reliability of updated system information delivery and improves probability of system information acquisition in region of dominant co-channel interference.
