Abstract: A method and system for improving interoperability of a radio network controller and a base station in cellular systems with downlink congestion control is disclosed. A message is sent from a base station to a radio network controller after the base station has discarded at least one transport block. The message sent to the radio network controller may be forwarded by the radio network controller to additional radio network controllers serving users affected by the discard of the at least one transport block.

Abstract: A method and system where a common channel (such as a beacon channel) (24) i s swept over a specified coverage area of a sectorized cell (100) is disclosed . An idle WTRU (16) saves pertinent information such as received power and tim e of reception of the last several readings of the common channel. On the WTRU 's next access, the information is sent to the network to determine the WTRU's location, its direction of travel and a speed estimate which is valuable for radio resource management.

Abstract: An improved method of network management, particularly in the context of standards IEEE802.11 and IEEE802.11k, through two new MAC measurements, with attendant advantages. The two new measurements include WTRU uplink traffic loading measurement, and an AP service loading measurement and is generally applicable at least to layers 1 and 2 as applied to a least 802.11k in the context of OFDM and CDMA 2000 systems, but is applicable to other scenarios as well. A Method for determining and advertising congestion is also provided for a Wireless Local Area Network (WLAN) system. The present invention also introduces a method for managing congestion when congestion is detected. This aspect of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/ Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms.

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 use in an access point includes receiving a request for a reselection message from a wireless transmit/receive unit (WTRU). The reselection message is generated in response to the request and includes: 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, to indicate the BSS selection preference; an expiration time indicator associated with each candidate BSS, to indicate a time period that the BSS may be considered for reselection; an indication of a measurement to be taken on a BSS and used in a target BSS reselection determination; and a margin by which the measurement must exceed a corresponding value for a currently selected BSS. The reselection message is transmitted to the WTRU. A reselection response message is received from the WTRU, indicating the target BSS reselection determination.

Abstract: An access point operates in an 802.11 wireless communication network communicating with a client station, and includes a smart antenna for generating directional antenna beams and an omni-directional antenna beam. An antenna steering algorithm scans the directional antenna beams and the omni-directional antenna beam for receiving signals from the client station. The signals received via each scanned antenna beam are measured, and one of the antenna beams is selected based upon the measuring for communicating with the client station. The selected antenna beam is preferably a directional antenna beam. Once the directional antenna beam has been selected, there are several usage rules for exchanging data with the client station. The usage rules are directed to an active state of the access point, which includes a data transmission mode and a data reception mode.

Abstract: A method for changing a channel in a wireless local area network (WLAN) to alleviate congestion and high interference levels, the WLAN having an access point (AP) and at least one station, begins by determining a list of candidate channels. A channel is selected from the candidate list and is evaluated against predetermined criteria. If the selected channel meets the predetermined criteria, then all of the stations communicating with the AP are disassociated and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list and the selecting step is repeated if there are additional candidate channels.
