Abstract:
1. Apparatus for a multi-user communication system defining a radio link upon which both closed-loop, power-controlled communication services and best-effort communication services are effectuable thereon between a sending station and at least a first receiving station, said apparatus for facilitating allocation of power levels of at least a first best-effort communication signal communicated upon the radio link pursuant to effectuation of at least a first best-effort communication service between the sending station and the at least the first receiving station, said apparatus comprising: a storage element for storing indicia associated with prior transmit power levels at which closed-loop, power-controlled communication signals have previously been sent upon the radio link; a predictor coupled to said storage element for accessing the indicia associated with prior transmit power levels at which the closed-loop, power-controlled communication signals sent upon the radio link to effectuate the guaranteed QoS communication services are transmitted, said predictor for predicting subsequent power levels at which the closed-loop, power-controlled communication signals shall subsequently be transmitted; an allocator coupled to said predictor to receive indications of predictions made thereat and coupled to receive indicia associated with present power levels at which the closed-loop, power-controlled signals are sent, said allocator for allocating the power levels at which subsequently to transmit the at least the first best-effort communication signal, the power levels allocated being related to a ratio of a link allocation interval to a power control command interval, and said allocator further for selectably reallocating the power levels at which subsequently to transmit the at least the first best-effort communication signal, reallocation made in manners to reduce the power levels at which subsequently to transmit the at least the first best-effort communication signal.
