Abstract: A method and system wherein users are encouraged to participate in cooperative positioning among wireless transmit/receive units (WTRUS) (102) is disclosed. Participating WTRUS determined to be suitable for providing positioning information for target-WTRUS are identified and sent a broadcast message requesting positioning information regarding a target-WTRU(s) (102). Participating wireless transmit/receive units that report positioning information are given a reward or credit.

Abstract: This invention relates to wireless local area networks, and particularly to the IEEE 802.11 family of standards. It consists of a method and apparatus that can be implemented in access points (APs) and subscriber wireless transmit/receive units (WTRUs), in order to allow an AP to initiate re-association of a WTRU to itself or a different AP. The invention improves the robustness of the network by enabling more efficient load balancing, congestion control, and roaming, without compromising the user experience.

Abstract: A method for accelerating discovery of access points (APs) in a wireless local area network begins by transmitting an advertisement packet by an AP via at least one channel other than a channel on which the AP transmits beacon signals. The advertisement packet is received by a station (STA), which then determines whether to associate to the transmitting AP. The advertisement packet can include reassociation information, such that the STA can associate to the AP based on the information in the advertisement packet, or timing information, such that the STA can tune to the AP and receive the AP's beacon without dwelling on the AP for an extended period of time.

Abstract: A silent measurement period (SMP) for a selected channel in an allowable channel set (ACS) of the access point (AP) is set. During the SMP, the AP does not serve wireless transmit/receive units (WTRUs) within its coverage area and reserves its channels for other BSSs. A normal operating channel of the AP is changed to the selected channel upon initialization of the SMP (225). Characteristics of the selected channel is measured during the SMP (235). The operating channel of the AP is changed back to the normal operating channel when the duration of the SMP expires (245).
