    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. The method also includes transmitting the HARQ packet to the base station in a transmit time interval (TTI) corresponding a first or second partition of an uplink allocation interval on a second carrier. The method further includes receiving HARQ feedback information corresponding to a previous HARQ packet transmission. Furthermore, the method includes determining a TTI in a subsequent uplink allocation interval based on the partition of the uplink allocation interval in which the HARQ packet is transmitted if the HARQ feedback information indicates negative acknowledgement. Moreover, the method includes transmitting the HARQ packet to the base station in the determined transmit time interval of the subsequent uplink allocation interval on the second carrier.

    Abstract: The present disclosure provides a method and apparatus for communicating data packets in a cloud cell. In one embodiment, a network node from which data packets are received is identified by the BS. If the data packets are received from a data gateway, a network node to which the data packets to be sent is identified. If the data packets are to be sent to a slave BS, partial processing, is performed on the data packets by the master BS. Furthermore, partially processed data packets are transmitted to the slave BS so that the slave BS performs complete processing on the partially processed data packets and transmits the completely processed data packets to the MS. If the data packets are to be sent to the MS, then complete processing of the data packets is performed by the BS and transmitted to the MS.

    Abstract: Beam selection is provided. A method for handover in a mobile station includes sending a scan request message for scanning a downlink (DL) beam with respect to a serving base station (BS) and a neighboring BS, to the serving BS, and receiving a scan response message; determining the DL beam for the MS by performing scanning with the serving BS and the neighboring BS based on the scan response message; sending a scan report message comprising a result of the scanning to the serving BS; when receiving an air-HO request message from the serving BS, generating an air-HO response message comprising information of a neighboring BS to which the MS hands over based on the air-HO request message; performing beam selection with the neighboring BS of the handover based on the air-HO request message; and performing the handover.

    Abstract: A method for performing discovery at a terminal in a communication system is provided. The method includes generating a discovery request message including discovery target information, transmitting the discovery request message to a Proximity Service (ProSe) server that is located in a core network of the communication system and that manages communication of the terminal, and receiving a result of a discovery operation from another entity that performs the discovery operation of the terminal using discovery identification information about the terminal. The other entity is selected based on the discovery target information by the ProSe server.
