Abstract: A method for improved decoding of hybrid automatic repeat request (H-ARQ) transmissions may include attempting to verify a physical layer (PHY) cyclic redundancy check (CRC) for a candidate H-ARQ encoder packet. If the PHY CRC is not verified, medium access control layer protocol data units (MPDUs) may be identified in the candidate H-ARQ encoder packet, and attempts may be made to verify a medium access control layer (MAC) CRC for each MPDU in the candidate H-ARQ encoder packet.

Abstract: A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.

Abstract: Methods and apparatus for decoding MAP information elements (MAP IEs) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame, even when the received downlink (DL) or uplink (UL) MAP message cyclic redundancy check (CRC) fails, may be provided. By continuing to parse the MAP IEs in the MAP message despite a CRC failure in the MAP message or a data burst, the packet error rate may be reduced, and the wireless system throughput may be increased.

Abstract: Methods and apparatus for base-station-assisted handover between WiMAX (Worldwide Interoperability for Microwave Access) and CDMA (Code Division Multiple Access) EVDO (Evolution-Data Optimized) or 1xRTT (one times Radio Transmission Technology, or 1x) networks during normal operation of a dual-mode mobile station (MS) are provided. By having a base station (BS) using one radio access technology (RAT) broadcast information about a BS in a neighboring cell employing a different RAT, the methods and apparatus may improve service continuity during handover.

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 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 (20) determines if sufficient network resources are available to conduct an inter-system soft handoff. If so, the base station controller (20) generates a set of signaling messages that cause a call processing resource to be allocated, and for the call to be processed at the second cellular system. The base station controller (20) then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit (28) by way of the second cellular system as well as via one or more base stations to which the base station controller (20) 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 of designing a network results in a network with an efficient addressing scheme which allows for filters to perform a simple logical operation. The process begins by arranging a plurality of nodes connected by a plurality of bi-directional links in a tree topology. Each node is assigned a range of consecutive flow process addresses such that each packet carried in a first direction on one of the bi-directional links has an address within the range A

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a service through an MBMS session. The apparatus receives a first notification of an upcoming suspension of the MBMS session. The apparatus requests establishment of a unicast bearer prior to the upcoming suspension of the MBMS session upon receiving the first notification. The apparatus receives a corresponding unicast version of the service of the MBMS session via unicast when the unicast bearer is established. In an aspect, the first notification may be received during a first MCCH modification period, the corresponding unicast version of the service is received via unicast during a second MCCH modification period. In an aspect, the apparatus may further receive a second notification that the MBMS session is suspended during the second MCCH modification period.
