Method and system for reselecting an access point

A method for use in an access point, comprising:

• receiving a request for a reselection message from a wireless transmit/receive unit (WTRU);
• generating the reselection message in response to the request, the reselection message including:
• at least one first identifier of one or more candidate basic service sets (BSSs) that may be considered for reselection;
• a preference indicator associated with each candidate BSS, wherein the preference indicator indicates an extent to which the associated candidate BSS may be preferred for selection;
• an expiration time indicator associated with each candidate BSS, wherein the expiration time indicator indicates a period of time that the associated 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 a target BSS reselection determination;
• and
• a margin by which a value of the measurement of the candidate BSS must exceed a corresponding value for a currently selected BSS;
• transmitting the reselection message to the WTRU;
• and
• receiving a reselection response message from the WTRU indicating the target BSS reselection determination of the WTRU.
