Abstract
A received channel power indicator (RCPI) value is used as a measure of the received RF power in the selected channel, measured at the antenna connector. This parameter is a measure by the PHY sublayer of the received RF power in the channel measured over the PLCP preamble and over the entire received frame. RCPI is a monotonically increasing, logarithmic function of the received power level defined in dBm.
Claims14
A method for receiving a received channel power indicator (RCPI) at an access point (AP), the method comprising:
- transmitting a wireless signal;
- receiving an n-bit RCPI parameter that is based on a measured radio frequency power of the wireless signal at a wireless transmit receive unit (WTRU) having a monotonically increasing logarithmic function, wherein n is a positive integer.
A wireless access point (AP) comprising:
- a transmitter configured to transmit a wireless signal;
- a receiver configured to receive an n-bit received channel power indicator (RCPI) parameter that is based on a measured radio frequency power of the wireless signal at a wireless transmit receive unit (WTRU) having a monotonically increasing logarithmic function, wherein n is a positive integer.
