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: A communication method, system and components are provided that includes use of traffic predictions determined by a wireless transmit/receive unit (WTRU). Preferably, the invention is implemented by predicting traffic in a wireless local area network (WLAN), between a WTRU and a WLAN access point (AP) that begins by determining a traffic level at the WTRU. Traffic prediction information is sent by the WTRU to the AP where it is used in conjunction with the generation of commands sent to WTRUs to control the manner of access by WTRUs to the WLAN via the AP. WTRUs receive instructions as to admission and are preferrably configured to receive and implement instructions to adjust the contention window used by the WTRU to transmit data.

Abstract: The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point.
