Abstract: A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of wireless user terminals. Each wireless user terminal includes a receiver and a controller that receives a plurality of orthogonal frequency division multiplexing (OFDM) signals on a first carrier frequency of a downlink. Each of the plurality of OFDM signals includes carrier frequency assignment information indicating a carrier frequency to transmit uplink data and spatial pattern information indicating a spatial pattern. In response to the carrier frequency assignment information of each of the plurality of OFDM signals, a transmitter and the controller of the wireless user terminal transmit a plurality of uplink signals. Each of the plurality of uplink signals are transmitted on the indicated carrier frequency and using the indicated spatial pattern.

Abstract: A method and apparatus are used for providing assistance data to wireless transmit/receive units (WTRU)s. The assistance data may include information regarding neighboring access points (AP)s. The assistance data may be transmitted to WTRUs using multicast, broadcast, and/or point-to-point signaling. The assistance data may be used to facilitate ring and handover of WTRUs from one AP to another.

Abstract: A method and apparatus may be used for exchanging measurements in wireless communications. The apparatus may receive a request. The request may be a measurement request, and may include a request for a measurement of a parameter. The apparatus may transmit a report. The report may be a measurement report, and may include the requested measurement of a parameter. The apparatus may store the requested measurement of the parameter in a management information base (MIB).

Abstract: A radio resource control unit configured to determine values for use by radio resource management functions includes a measurement reception and storing unit and a measurement processing unit. The measurement reception and storing unit is configured to obtain and store air interface actual values and predictive values; and generate and store a timestamp indicating a time when each actual or predictive value is obtained. The measurement processing unit is configured to process the actual and predictive values to provide an output value; determine an occurrence of a transient period, which is a period of time when a radio link is unstable; and determine whether the actual value is valid by comparing the timestamp of the actual value to the occurrence of the transient period, and on a condition that the timestamp is within the transient period, then the actual value is determined to be not valid.

Abstract: A method for determining values for use by radio resource management functions is disclosed. Air interface actual values and predictive values are obtained and stored. A timestamp indicating a time when each actual value or predictive value is obtained is generated and stored. The actual values and the predictive values are processed to provide an output value.

Abstract: A temporary (temp) dedicated channel (DCH) is used to support communications. The temp-DCH channel is a channel that is assigned to a user having a set duration. After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing the temp-DCH channel, determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

Abstract: A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.
