    Abstract: A base station (BS) may determine a fixed modulation scheme, a fixed PDU payload size, and a fixed number of PDUs per downlink burst for transmission of multicast data to subscriber stations. The BS may allocate downlink bursts to deliver the multicast data to the subscriber stations via PDUs using the fixed modulation scheme, the fixed PDU payload size, and the fixed number of PDUs per DL burst. A subscriber station (SS) may bypass the processing of multicast frames if the SS does not belong to any multicast groups. An SS may search for multicast connection identifiers (CIDs) in DL MAP IEs in multicast frames if the SS belongs to at least one multicast group. The SS may bypass the parsing of a PDU's MAC header within a corresponding downlink burst in the multicast frame in response to identifying a multicast CID in a DL-MAP IE in a multicast frame.

    Abstract: Certain embodiments of the present disclosure propose a technique that may be utilized to accelerate the processing of MAC management messages by an MS, allowing the MS to return to a lower power state sooner, thereby conserving power. An indication of whether or not data bursts in a downlink (DL) sub-frame contain MAC management messages may allow the MS to avoid needlessly processing of data bursts and return to a low power state sooner.

    Abstract: Techniques presented herein allow a wireless device, (e.g., a mobile station, MS) to automatically enter a low power state when detecting silence based on monitored VoIP transmissions. Automatically entering the low power state may help the wireless device conserve power. In addition, for certain types of scheduling services in which bandwidth is allocated to the wireless device from within a system (e.g., Unsolicited Grant Service or extended real time polling service), automatically entering the low power state when silence is detected may also free up bandwidth (i.e., that would have otherwise been allocated to the wireless device entering the low power state) for allocation to other wireless devices in the system.

    Abstract: Methods and apparatus for indicating a base station's amount of ranging traffic to a mobile station (MS) and for selecting a base station (BS) for performing ranging based on the ranging traffic indication are provided. This notification may occur via a ranging loading parameter, such as a ranging loading factor (RLF) indicating the ratio of used ranging slots to available ranging slots, transmitted as a new TLV (Type-Length-Value) within the Uplink Channel Descriptor (UCD) of a (potential) serving BS or in the UCD of a Neighbor Advertisement (MOB_NBR-ADV) message for a neighbor BS. By selecting a BS with a certain level of unused ranging slots, the MS may exponentially decrease the ranging overhead (i.e., the average waiting time for the ranging procedures) when compared to a conventional MS that does not consider a BS's ranging overload when trying to perform ranging with the BS.
