Abstract: A method and system for minimizing battery power consumption of user equipment (UE) during inter-frequency cell discovery in heterogeneous network is disclosed. UE receives background scan configuration for specified frequency from the network and performs the background scan for detecting inter-frequency cell. The UE detects an inter-frequency cell on the frequency indicated in the background scan configuration, during the inactive time of DRX cycle. Further, UE indicates the physical cell identity of the detected cell to the network. Then the UE activates the normal measurement gap provided previously or the network configures normal measurement gap to the UE if not provided previously. Further, UE performs Reference signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) measurements of the detected cell. Then the UE reports these measurements to the network when the measurement report event condition is satisfied and the network handovers the UE to the detected cell.

Abstract: Methods and apparatuses are provided in which a user equipment (UE) receives a system information block (SIB) from a network. The UE identifies at least one downlink (DL) period based on a first uplink (UL)/DL configuration included in the SIB. The UE monitors a physical downlink control channel (PDCCH) during the at least one DL period using a discontinuous reception (DRX) operation. The UE obtains downlink control information (DCI) for indicating at least one second UL/DL configuration as a format for one or more time intervals from the monitored PDCCH. The UE determines the format for the one or more time intervals based on the obtained DCI. The monitoring of the PDCCH includes monitoring the PDCCH in an active time of a DRX cycle. The active time includes a time when the UE performs continuous reception.
