Abstract:
1. An assembly for a radio communication system having a network infrastructure for communicating data with a plurality of mobile stations, the data forming portions of communication signals transmitted at selected power levels, said assembly for facilitating selection of the power levels at which mobile stations are to transmit the communication signals, said assembly comprising: a signal generator coupled to the network infrastructure for generating, during selected intervals, a transmit power indication signal for broadcast transmission to the plurality of mobile stations, the transmit power indication signal indicating a maximum allowable power level at which each of the plurality of mobile stations are to transmit the communication signals, and for generating a power correction information signal for transmission to a selected at least one of the plurality of mobile stations, the power correction information signal for use by the mobile station in selecting a power level at which to transmit the communication signals a mobile-station power-level calculator positioned at the selected at least one of the plurality of mobile stations, said mobile-station power-level calculator operable, responsive to the value of the transmit power indication signal and to the value of the power correction information signal, to calculate a power-level at which communication signals are to be transmitted by the selected at least one mobile station wherein the radio communication system defines beacon intervals within which beacon signals are broadcast by the network infrastructure, and wherein the transmit power indication signal is generated for broadcast as part of at least one beacon signal; wherein the radio communication system defines polling periods during which the network infrastructure polls a selected one of the plurality of mobile stations; and wherein the power correction information signal is transmitted to the selected at least one of the mobile stations when the network infrastructure polls the selected at least one of the mobile stations.
