Abstract: Techniques for signaling a mobile communications device in a special operating state that data bursts contain messages relevant to the special operating state. The signaling may be implemented using one or more bits in a frame control header (FCH). As a result, the mobile communication device may be decode the FCH first and decode data bursts only if there is an indication the data bursts contain a relevant message. Power savings may be achieved at the mobile communications device by avoiding decoding data bursts with no relevant messages.

Abstract: Techniques presented herein disclose handover using increased probability of the fast ranging success. Propagation delay of the RF signal transmitted from an MS to a target BS may be estimated based on a known propagation delay to a current serving BS and a relative difference in propagation delays to the current serving BS and the target BS, for example, as indicated by different receive times of preamble sequences transmitted from the current serving BS and the target BS.

Abstract: 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.

Abstract: 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.

Abstract: Certain embodiments of the present disclosure provide a method for supporting multicast and broadcast services (MBS) with multiple-input multiple-output (MIMO) capabilities. This can be achieved by adding specific MIMO information into existing MBS-MAP messages while providing backward compatibility.

Abstract: A method for intra-user quality of service (QoS) uplink scheduling may include determining scheduling types associated with active uplink connections that are maintained by the subscriber station. The method may also include determining QoS parameters corresponding to the different scheduling types. The method may also include scheduling the active uplink connections for uplink transmissions based on the different scheduling types and their corresponding QoS parameters.

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.

Abstract: Certain embodiments of the present disclosure may allow for transmitting location information from a mobile station to a base station. The mobile station can determine differential location information (DLI) of the mobile station relative to an absolute location of the mobile station and transmit the DLI to the base station. The base station can receive DLI from the mobile station, the DLI indicating a location of the mobile station relative to an absolute location, and adjust parameters of the mobile station based, at least in part, on the DLI.

Abstract: Embodiments of the present disclosure allow a HARQ transmitter to provide a receiver an indication of the protocol data units (PDUs) that should not be expected because they are part of a data burst that has been retransmitted a maximum allowable number of times. The indication message may contain a maximum serial number contained in the data burst that has reached the maximum number of retransmissions, or the serial number of a first PDU in the next data burst.

Abstract: Certain embodiments of the present disclosure present methods and apparatuses for enhancing the dedicated ranging procedure. Certain embodiments improve probability of correct reception of a ranging code from a mobile station by accumulating two or more copies of the ranging code received from the MS on two or more different frames in a transmit opportunity. Certain aspects improve probability of correct reception of the ranging code by modifying timing of uplink transmission.

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.
