Abstract: A method and system for uplink-downlink transmission of message in a network. The method includes establishing, by a user equipment (UE), a security context for data transmission between the UE and a serving gateway in the network; generating, by the UE, in an idle mode, a data message including an encrypted data packet, the encrypted data packet being generated by encrypting a data packet to transmit to the serving gateway based on the security context; transmitting, by the UE, in the idle mode, to a base station (BS), a random access channel (RACH) message including a UE identifier (ID); receiving, by the UE, in the idle mode, from the BS, a contention resolution message including grant information for an uplink (UL) transmission; and transmitting, by the UE, in the idle mode, to the BS, the data message including the encrypted data packet.

Abstract: A method and an apparatus are provided for determining a configuration for a radio frame. A transition from a period of inactivity to a period of activity is detected in a configured discontinuous reception (DRX) cycle. A category of at least one subframe of the radio frame that is likely to be encountered during the period of activity is determined, if a dynamic reconfiguration of time division duplex (TDD) uplink (UL)—downlink (DL) configurations is enabled. The category of the least one subframe includes one of a flexible subframe and a fixed subframe.

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.

Abstract: A method and an apparatus for activating and deactivating secondary cells in a carrier aggregation environment are provided. In one embodiment, a Medium Access Control (MAC) Control Element (CE) command is received from a base station for activating/deactivating a secondary cell associated with a User Equipment (UE). The secondary cell configured for the UE is activated/deactivated based on the MAC CE command. Further, a first uplink grant is received from the base station upon activation/deactivation of the secondary cell. Accordingly, quality information (e.g., channel quality information, sounding reference signal information, and the like) associated with the cell(s) is transmitted to the base station in the received first uplink grant over a physical uplink shared channel. Furthermore, a hybrid automatic repeat request entity associated with the secondary cell is reset.

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.
