    • A wireless communication network includes a base station system that transmits sector congestion information to influence mobile station sector selection processing. In an exemplary embodiment, where at least some of the mobile stations being supported by the network autonomously select the network sector from which they wish to receive forward link packet data transmissions, an exemplary base station influences that sector selection processing by transmitting congestion information on a per sector basis. Complementing that transmission by the network, an exemplary mobile station incorporates consideration of the sector congestion information into its autonomous sector selection processing logic. Thus, where potentially large numbers of mobile stations individually select the “best” sector from a candidate set of sectors, the network can perform load balancing by advertising sector congestion levels, so that mobile stations can choose (or avoid choosing) a given sector based at least in part of the congestion information.

    • A method of reverse link power control for a reverse packet data channel in a wireless communication system allows a mobile station to autonomously change its data transmission rate. The mobile station transmits packet data over a reverse packet data channel having a data rate variant transmit power level that varies based on a transmit data rate on the packet data channel. The mobile station further transmits control signals over a reverse control channel associated with the reverse packet data channel. The transmit power level of the reverse control channel is such that the transmit power level does not vary with the transmit data rate on the packet data channel. The radio base station measures the strength of the received signals on the reverse control channel, compares the measured strength to a power control set point, and generates a power control signal responsive to the comparison of the control signal to the power control set point.
