Abstract:
1. A method implemented in a wireless transmit/receive unit (WTRU) for providing service availability information, comprising: receiving a signal transmitted from a base station, said signal identifying a plurality of potentially available services; measuring a power level and interference level of the received signal; deriving an estimate of a power level of each potentially available service based on the power level of the received signal and predetermined power offsets associated with each potentially available service, wherein the power offset associated with each potentially available service is a ratio of the highest power the base station may dedicate to each potentially available service over the power at which the base station transmits its beacon; calculating an estimate of a signal-to-interference ratio (SIR) for each potentially available service from the estimate of a power level of each service and the measured interference level; calculating a service availability indicator for each potentially available service by dividing the estimated SIR with a target SIR; and outputting service availability indicators for each potentially available service.
