Abstract:
1. An integrated circuit (IC) comprising: a measuring unit configured to measure operating parameters of each channel in an allowable channel set (ACS) upon activating the IC; and a channel selector configured to select a channel different than a current operating channel used by the IC for communication with a plurality of wireless transmit/receive unit (WTRUs), wherein the channel selector determines candidate channels based on the measured operating parameters, and selects from the candidate channels a new operating channel by performing the following optimization channel selection process: computing predicted channel utilization for all of the candidate channels; selecting a channel from the candidate channels with the smallest predicted channel utilization; determining if the selected channel with the smallest predicted channel utilization is different than the current operating channel; determining whether the channel utilization of the current operating channel is greater than the channel utilization of the selected channel with the smallest predicted channel utilization by at least a predefined threshold, if the selected channel with the smallest predicted channel utilization is different from the current operating channel; and ending the optimization channel selection process if the selected channel with the smallest predicted channel utilization is the same as the current operating channel, or if the channel utilization of the current operating channel is not greater than the channel utilization of the selected channel with the smallest predicted channel utilization by at least a predefined threshold, wherein the IC disassociates with any of the WTRUs that are associated with the IC through the current operating channel if the channel utilization of the current operating channel is greater than the channel utilization of the selected channel with the smallest predicted channel utilization by at least a predefined threshold.
