Abstract: The present invention provides a method and system for performing Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment. In one embodiment, a method includes receiving resource allocation information from a base station in a scheduling interval of a first carrier, where the resource allocation information indicates resources and transmit time interval in an uplink allocation interval. The method includes transmitting the HARQ packet to the base station in the transmit time interval of the uplink allocation interval on the second carrier if the transmit time interval corresponds to a first partition of the uplink allocation interval. If the transmit time interval corresponds to a second partition of the uplink allocation interval, the method further includes transmitting the HARQ packet to the base station in the transmit time interval of the uplink allocation interval on the second carrier according to a second type of HARQ process.

Abstract: A method to manage a Radio Resource Control (RRC) connection in an evolved NodeB (eNB) in a wireless communication system supporting a Device to Device (D2D) scheme is provided. The method includes starting an inactivity timer to control a User Equipment (UE) to transition into an RRC idle state after setting up an RRC connection with the UE. The method also includes allocating a D2D resource to the UE when a resource request message to request the D2D resource for a direct communication between UEs is received from the UE. The method further includes transmitting a resource response message including information related to the allocated D2D resource to the UE and stopping the inactivity timer. The method includes releasing the allocated D2D resource and restarting the inactivity timer based on a predetermined option.
