Patent ID: 7286486

Claim:
In a wireless communication system including at least one access point (AP) and at least one wireless transmit/receive unit (WTRU) associated with the AP, a method of compensating for interference, the method comprising: (a) the AP performing a noise floor measurement based on a received signal strength indicator (RSSI); (b) determining whether the noise floor measurement is available in the absence of carrier lock; (c) setting a required received power (RRP) from uplink interference (RRP UI ) to the value of a previous activation, if there is no available noise floor measurement available in the absence of carrier lock; and (d) setting the RRP UI to the following equation, RRP UI =I AP +(C/I) req — low , if the noise floor measurement is available, wherein I AP is an estimate of the noise floor at the AP, and (C/I) req — low is a configurable parameter representing the typical required carrier-to-interference ratio to have a reasonable probability of success at a low rate.
