Abstract: Method and apparatus employed by wireless network components such as access points (APs) for controlling transmitting power level of individual wireless transmitter/receiver units (WTRUs) by establishing a power transmit level based on prior transmit and receiving transmission and reception statistics such as signal to noise ratio (SNR), bit error rate (BER), frame error rate (FER) and/or the like. Power transmit level information is preferably communicated through any one of a clear to send (CTS), request to send (RTS), data and acknowledge (ACK) frame. Alternatively the power control information may be inserted into a beacon frame or an individual control frame specifically designated for power control. The WTRUs preferably have battery level sensors and adjust power control level responsive to a sensed battery level. Alternatively, the APs and WTRUs may reverse roles and the WTRUs may provide power transmit level information to an AP to facilitate transmissions by the AP.

Abstract: A method and wireless communication system may be used for transferring management information. An access point (AP) may transmit a management information base (MIB) information request including a category field and an action details field to a wireless transmit/receive (WTRU). In response to receiving the information request, the WTRU may determine whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU may compile management information stored in a MIB located in the WTRU and transmit a MIB information report to the AP. The MIB may list a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements. The AP may include a MIB for storing MIB information of the WTRU. The AP may transmit the stored MIB information of the WTRU in response to a request.

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 correct escape mechanism is determined according to interference type. Transmission is arranged so that interference may be measured at all time slots as needed to compute a measure of variance in interference in time slots (45). If the variance is above a predetermined value (62), time division duplex escape mechanisms are employed. If the variance is below a predetermined value, appropriate escape mechanisms are employed depending on whether the escape mechanism is being implemented during an uplink (324) or downlink (64). Interference causing FDD WTUs may be handed over to carrier bands to control interference experienced by TDD users.

Abstract: In a wireless communication system including an access point and at least one wireless transmit/receive unit (WTRU), a method for adaptive radio resource management begins by examining a frame error rate value of a WTRU. Then, a channel utilization value of the WTRU and a current data rate of the WTRU are examined. System parameters for the WTRU are adjusted based on the examined variables.

Abstract: Se divulgan un método y sistema para proveer datos de asistencia a unidades inalámbricas de transmision/recepcion (WTRUs). Los datos de asistencias incluyen informacion referida a los puntos de acceso vecinos del punto de acceso. Los datos de asistencia son transmitidos a WTRUs que utilizan senalizacion de tipo multidifusion y/o radiodifusion y facilitan roaming y traspaso de WTRUs de un punto de acceso a otro.
