    Abstract: A method and apparatus for use by a first transceiver, (e.g., wireless transmit/receive unit (WTRU), access point (AP), node) for adjusting the transmission rate of packets transmitted to a second transceiver based on signals the first transceiver receives from the second transceiver. In one embodiment, a transmission packet error rate (Tx PER) process is used to adjust the packet transmission rate. In another embodiment, a relative signal strength indicator (RSSI)-based process is used to determine the RSSI of packets received at the first transceiver from the second transceiver for adjusting the packet transmission rate. In another embodiment, transmission quality indicators are measured at the second transceiver and are sent to the first transceiver, which derives a new packet transmission rate therefrom. The Tx PER and RSSI-based processes may be used individually, in combination, or in conjunction with other processes.

    Abstract: The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multi cast service (MBMS) data over a high speed down link packet access (HSDPA) channel. A Node B may pre-allocate a time frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.

    Abstract: A method and apparatus for re-allocating radio resources in a wireless communication system includes observing an original allocation of radio resources within the system. The method collects system statistics over an observation interval, determines an optimal allocation of radio resources based on the observed statistics, and re-allocates the radio resources based on the determination.

    Abstract: A method for radio resource management (RRM) in a wireless local area network (WLAN) having an access point and a station begins by obtaining a first group of parameters from a current traffic channel. Measurements from all available channels are taken for a second group of parameters. The radio resources of the WLAN are autonomously managed by selectively invoking at least one RRM algorithm that uses at least one parameter. A RRM algorithm may be invoked based upon results produced by a previously executed RRM algorithm, whereby RRM algorithms may be continuously invoked such that the radio resources are autonomously managed.

    Abstract: A method (100) 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.
