The measurements to be taken by the WTRU 106 include at least one of, but are not limited to, a load metric indicating the amount of radio resources that are used, received signal quality, (such as a signal-to-noise ratio (SNR), a signal-to-interference and noise ratio (SINR), a received signal power level, or the like), an expected instantaneous data rate achievable for transmitting or receiving packets to/from the AP based on the received signal quality, an expected average throughput (EAT) achievable for transmitting or receiving packets to/from the AP based on channel utilization (CU) and the received signal quality. The CU is defined as the fraction of time the wireless medium is perceived as “busy” on the frequency channel. The EAT may be estimated by the following formula: EAT=data rate�(1−CU).
