    摘要: Managing radio resources and power for OFDMA uplinks is disclosed in which a threshold transmission rate for the reverse link is used by base stations to compare against the achievable reverse link transmission rate of a particular AT within the sector serviced by the base station. When the calculated rate is higher than the threshold rate, the base station allocates maximum power to the AT. Otherwise, when the calculated rate is lower than the threshold rate, zero power is allocated to the AT.

    摘要: Congestion control provides congestion control for one or more shared resources in a wireless communication network. In one exemplary embodiment, a congestion controller manages congestion of shared packet data channels by under-serving selected ones of the data connections sharing the packet data channel. Such selective under-serving may be effected by biasing scheduling of service on the packet data channel toward maximum throughput scheduling such that connections associated with poor radio conditions are naturally under-served. Further, the controller may manage congestion of other shared resources, such as shared transmit power resources, wherein congestion of the shared power resource is managed by under-allocating transmit power to selected ones of the connections. Congestion is sensed, for example, by monitoring transmit buffer occupancy levels, and/or reserve power levels. In either case, congestion relief may be amplified where operation of the controller “triggers” flow control on the intentionally under-served ones of the active data connections.

    摘要: A system and method for synchronized and coordinated beam switching and scheduling in a wireless communications system is provided. A method for controller operation includes determining a beam cycle pattern, sharing the beam cycle pattern with neighboring controllers, receiving beam information from a communications device, generating scheduling information from the beam cycle pattern and beam cycle patterns from other controllers, receiving a transmission intended for the communications device, and causing the transmission to be transmitted to the communications device. The beam cycle pattern includes a list of beam patterns transmitted by the controller, and the transmission is transmitted using the scheduling information and the received beam information.

    摘要: System and method for dynamic resource allocation in wireless communications networks. A method for dynamically allocating resources of a contention channel comprises computing an expected delay for a transmission made by a user over the contention channel, determining a target probability of collision from the expected delay, computing an allocation of resources of the contention channel using the target probability of collision, and allocating resources of the contention channel using the computed allocation of resources.

    摘要: A method of scheduling wireless packet data traffic on a downlink packet data channel takes advantage of early decoding opportunities to decode the channel feedback reports before receipt of the mandated Lth repetition. The early-decoded channel feedback reports are promptly used in making scheduling decisions. Mobile stations are required to repeat transmissions of channel quality reports at least L times. The base station receives channel quality information report CFN from a first mobile station one or more times, but less than L times; and, prior to reception of the Lth repetition of CFN, successfully decodes CFN to form a first decoded report. Packet data transmissions on the downlink packet data traffic channel are scheduled based on CFN. A corresponding apparatus is also described.
