Method and apparatus for selecting a multi-band access point to associate with a multi-band mobile station

摘要

A method and apparatus may be used for selecting one of a plurality of multi-band APs to associate with a multi-band WTRU. The multi-band APs may broadcast frequency band information regarding multiple frequency bands on which the multi-band AP is configured to operate. The multi-band WTRU may select a multi-band AP to associate with and a frequency band to use to communicate with the selected multi-band AP based on the frequency band information. The multi-band AP may transmit frequency band information from the that indicates that a characteristic, (e.g., throughput, path loss, load, capacity, backhaul), of the selected frequency band and disassociate with the multi-band WTRU or to continue to associate with the multi-band WTRU via a different frequency band.

主权项

1. A method for use in a multi-band access point (AP), the method comprising:
receiving a probe request message from a multi-band wireless transmit/receive unit (WTRU), wherein the probe request message includes first frequency band information that indicates a multiple frequency capability of the WTRU; transmitting a probe response message to the multi-band WTRU, wherein the probe response message is responsive to the probe request message and includes information regarding multiple frequency bands supported by the multi-band AP, and wherein the multiple frequency bands include a first frequency band and a second frequency band; establishing an association with the multi-band WTRU on the first frequency band; transmitting second frequency band information to the multi-band WTRU; and subsequent to transmitting the second frequency band information, maintaining the association with the multi-band WTRU on the second frequency band or terminating the association with the multi-band WTRU.
