Abstract: Closed loop and open loop control mechanisms are disclosed for adjusting the power headroom in a mobile station. The closed loop control comprises receiving a load indication from a base station indicative of the reverse link load, and adjusting the power headroom of the mobile station based on the load indication. The open loop control mechanism comprises counting the number of times that the mobile station is power limited, and adjusting the power headroom threshold based on the count.

Abstract: 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.

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.

Abstract: 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.

Abstract: System and method for utility-based scheduling for SDMA transmissions on an uplink of a wireless communications network. A method comprises assigning a utility function to each user in a set of users, selecting a set of selected users from the set of users, assigning uplink transmission resources to each user in the set of selected users, and transmitting a control message to each user in the set of selected users. The selecting comprises iteratively selecting up to K users one user at a time from the set of users, wherein a combination of the selected users maximally increases a value of the assigned utility functions, wherein K is a maximum number of users in the set of selected users.

Abstract: Techniques are provided to assign radio resources with one of two or more types of assignments on a frame-by-frame basis. The first type of assignment uses subcarriers that are contiguous in both time and frequency, and the second type of assignment uses subcarriers that are disjoint and equally-spaced in frequency. The types of resource assignments can be multiplexed in a frame by dividing the frame into two zones, each zone of a different type. The demarcation between the first and second zones is implicitly indicated by the assignment messages for the mobile stations. Based on the loading conditions, the base station selects one of two demarcation strategies to use and communicates the selection implicitly by using one assignment message for a mobile station.

Abstract: A method and system of allocating a bandwidth and a power for a wireless user. The method includes for an allocated bandwidth determining a transmission power and adjusting the transmission power based on whether a bit rate and an error rate associated with the transmission power and the allocated bandwidth satisfy one or more predetermined criteria. The method further processing information associated with the adjusted transmission power and determining a power level indicator. Additionally, the method includes determining whether the power level indicator satisfies one or more predetermined third criteria. If the power level indicator is determined not to satisfy the one or more predetermined third criteria, the method includes adjusting the allocated bandwidth from the first bandwidth to a second bandwidth for the wireless user. Otherwise, the method includes keeping the allocated bandwidth.
