    Abstract: A method and system to handle behavior of a carrier aggregation capable User Equipment (UE) that does not support simultaneous reception and transmission in overlapped Downlink (DL)-Uplink (UL) sub frames during inter-band Carrier Aggregation (CA) for cell specific TDD configuration is disclosed. The method specifies whether the UE is allowed or not allowed to monitor the PDCCH sub frames during overlap of DL-UL sub frames by signaling the UE with a resultant TDD configuration that is applicable to component carriers of the PCell and one or more SCells. The method also addresses handling of the DRX timers by defining the active time for common DRX operation by the UE for all component carriers. The method enhances the 3GPP specification to enable UE to better handle reception and transmission during overlap of DL-UL sub frames in cell specific TDD configuration during inter-band CA.

    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 providing selective protection of data exchanged between user equipment (UE) and network is disclosed. The selective protection is applied to a packet, a bearer or an access point name for secure exchange of data between the UE and the network. The network decides to apply selective protection based on configuration of network, configuration of UE, load in the network, battery power availability of UE, type of application running on UE. Further, the UE can request for selective protection based on the type of application running on UE and the battery level availability of the UE. The selective protection is either enabled or disabled dynamically by the network. Further, various mechanisms for applying selective protection for each bearer, each packet and each Access Point Name (APN) are disclosed. Additionally, the method for identifying a secured and a non secured bearer has also been disclosed.

Furthermore, the method includes indicating to a base station that the remaining subframes and the corresponding HARQ processes are reserved for the LTE module operation to resolve the in-device co-existence interference. Moreover, the method includes receiving scheduling pattern indicating subframes and corresponding HARQ processes reserved for the LTE operation or derived DRX parameters from the base station based on the indication.
