    摘要: Methods and apparatuses for scheduling transmissions between a base station and multiple user stations in a broadband wireless access network may include a subscriber station generating a bandwidth request which includes one of a limited number of available and predefined preamble sequences and a data portion identifying the resources requested. The subscriber station randomly selects a contention slot in a wireless channel, allocated by the base station, for sending a bandwidth request. The receiving base station is able to detect the preamble sequence of bandwidth requests and differentiate between subscribers even when bandwidth requests of two or more subscribers may collide by virtue of selecting the same contention slot. In this manner, latency and overhead of bandwidth requests may be improved. Additional variants and embodiments are also disclosed.

    摘要: Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for assigning transmission power to one or more components carriers in an uplink transmission utilizing carrier aggregation. In one embodiment, power is assigned to a component carrier based on the priority level of the component carrier. In another embodiment, power is assigned based on absolute priority order. In yet another embodiment, power is assigned based on relative priority order.

    摘要: Briefly, in accordance with one or more embodiments, a pathloss gap between a downlink pathloss from a base station to a mobile station and an uplink pathloss from the mobile station to the base station is estimated. An initial offset value for uplink power control of the estimated pathloss gap is calculated based at least in part on said estimating. An offset value for an uplink data channel or an uplink control channel, or combinations thereof, is set based at least in part on the initial offset value. The pathloss gap for uplink power control is compensated using the set offset value.
