Abstract: Certain embodiments of the present disclosure may allow WiMAX signaling overhead to be reduced by sending burst allocation information to MSs using messages that may be transmitted using more efficient modulation coding schemes (MCSs) than that allowed for DL-MAP and UL-MAP messages. For example, burst allocation information may be sent in SUB-DL-UL-MAP or HARQ-MAP messages that may be encoded with selectable MCSs that result in higher data rate than an MCS used for conventional DL-MAP and UL-MAP messages. For certain embodiments, MSs may be partitioned into groups based on CINR and the burst allocation information for each group may be transmitted using an MCS that is appropriate for that group based on the CINR for MSs in that group.

Abstract: A method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller determines if sufficient network resources are available to conduct a inter-system soft handoff. If so, the base station controller generates a set of signaling messages that cause call processing resource to be allocated and for the call to be processed at the second cellular system. The base station controller then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit by way of the second cellular system as well as via one or more base stations to which the base station controller is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

Abstract: A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system. The link load message include peak queue length and average frame rate information.

Abstract: A method for parallel acquisition of system information from multiple base stations may be implemented by a mobile station. The method may include determining scheduled times for transmission of the system information from the multiple base stations based on parameters included in messages from the multiple base stations. The method may also include creating a schedule list that comprises the scheduled times. The method may further include tuning to the base stations at the scheduled times that are specified in the schedule list in order to receive the system information from the base stations.

Abstract: A method for priority-based network congestion control may be implemented by a network entity. The method may include determining one or more priorities associated with a service request that is being processed by the network entity (702). The method may also include determining resource availability (704). The method may also include determining whether to grant the service request based on the one or more priorities associated with the service request and the resource availability (710).

Abstract: Embodiments of the present disclosure allow a MS to dynamically adjust the mapping of a physical CINR measurement to an effective CINR. For some embodiments, an effective CINR value may be generated based on a physical CINR value and a measured packet error rate (PER) over one or more time periods. Depending on the comparison result between the measured PER and a target PER, the physical CINR is lowered or increased before mapping to the effective. CINR. The effective CINR reported back to a BS is thus dynamically adjusted for allowing the BS to select a coding scheme that effectively compensates for changes in channel conditions, which may improve system performance.
