    摘要: This application provides techniques for robust handover to a target base station, based on performing initial ranging with the target base station. The techniques might generally include scanning neighboring base stations (BSs), selecting a target BS for a handover at least based on results of the scanning, performing initial ranging with the target BS, and sending a Handover Request to the target BS.

    摘要: Embodiments of the present disclosure provide techniques for processing a HARQ data burst and/or a HARQ ACK message in the event a HARQ ACK message falls within a scanning or an unavailable interval of an MS. For certain embodiments, a HARQ ACK message may be postponed if it falls within the scanning or the unavailable interval of the mobile station. For certain embodiments, the HARQ data burst transmission may be postponed if the corresponding HARQ ACK message falls within a scanning or an unavailable interval of the mobile station. For certain embodiments, the HARQ ACK may be transmitted or received even if it falls within the scanning or the unavailable interval of the mobile station. However, the HARQ ACK message may not be processed during the scanning/unavailable interval.

    摘要: Certain aspects of the present disclosure present techniques for requesting and granting bandwidth reservations during network entry and network reentry processes. The subscriber station transmits a request message to the base station including a bandwidth reservation for uplink allocation for at least one subsequent request messages to be transmitted. The base station transmits a response message and an uplink allocation for the at least one subsequent request message to the subscriber station.

    摘要: Certain embodiments of the present disclosure proposes a flexible method for scheduling of an uplink transmission simultaneously considering all active connections of a mobile station. A decision on scheduling priority can be made based on a metric that comprises QoS parameters and current traffic measurements. The weight factors may be applied for every QoS parameter per schedule type providing flexibility of the scheduling algorithm. The proposed scheduling algorithm may be applied to satisfy different QoS requirements for each service provider and application by changing weight factors if required.
