Claim:
An access point comprising: a transceiver configured to receive a request for a reselection message from a wireless transmit/receive unit (WTRU); a medium access control (MAC) message generator configured to produce the reselection message in response to the request, the reselection message including: identifiers of one or more candidate basic service sets (BSSs) that should be considered for reselection; identifiers of one or more candidate BSSs that should not be considered for reselection; preference indicators which indicate an extent to which each candidate BSS is preferred for selection; an expiration time indicator that indicates a period of time that a candidate BSS may be considered for reselection; an indication of a measurement to be taken on a candidate BSS and used as a part of the reselection process; and a margin by which a value of the measurement of the candidate BSS must exceed a corresponding value for a currently selected BSS; and the transceiver is further configured to: transmit the reselection message to the WTRU; and receive a reselection response message from the WTRU indicating a target BSS selected by the WTRU.
