1. A method for receiving a received channel power indicator (RCPI) at an access point (AP), the method comprising:

  • transmitting a wireless signal to a wireless transmit receive unit (WTRU); and

    receiving, from the WTRU, an RCPI parameter that is based on a measured radio frequency power measured over a data portion of a frame of the wireless signal at the WTRU, wherein the RCPI parameter is an 8-bit scalar value in a range between 0-220, wherein when the 8-bit scalar value is 0 , the RCPI parameter is less than −

    110 dBm, and when the 8-bit scalar value is 220 the RCPI parameter is greater than 0 dBm.
