  • Publication number: 20100208700
    Abstract: Methods and apparatus for improving performance and robustness of a handover procedure. For example, by handing over to a target base station (BS) that is co-located with a serving BS (i.e., a BS located in the same physical node as the serving BS), mobile station (MS) context transfers, handover preparation and downlink (DL) data continuity between the serving BS and the target BS may be simplified because the serving BS and the target BS are in the same physical node. Further, a location-based services advertisement (LBS-ADV) message may be enhanced to include sector center directions of the serving BS and neighboring BSs. Using this information, an MS may determine neighboring BSs that are adjacent to the serving BS and limit scanning operations and handovers to these adjacent BSs, thereby reducing the processing for those operations.

  • Publication number: 20100185910
    Abstract: Methods and apparatus for setting the connection identifier (CID) mask length of a Hybrid Automatic Repeat-Request (HARQ)-MAP or a SUB-MAP pointer information element (IE) in a compressed downlink map (DL-MAP) of an orthogonal frequency-division multiple access (OFDMA) frame are provided in an effort to reduce the number of false indications in the CID mask, while also striving, as a secondary concern, to reduce the CID mask length. In this manner, an individual mobile station (MS) may not waste processing, battery power, or time interpreting a HARQ-MAP message or a sub downlink/uplink map (SUB-DL-UL-MAP) message that was not intended for this particular MS. For some embodiments where the CID mask length is set to be small, the control overhead (i.e., the size of the HARQ-MAP or the SUB-MAP pointer IE) may be decreased, and more of the OFDMA frame may be available for data traffic.

  • Publication number: 20100128652
    Abstract: 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.
