Fast Link Adaptation and Transmit Power Control in Wireless Networks |
摘要 |
An open-loop fast link adaptation scheme is proposed in an OFDM system. An access point first transmits a downlink packet comprising an open-loop link metric to a wireless station. The open-loop link metric contains a transmit power of the downlink packet plus a receiver sensitivity of the access point. The wireless station measures a received signal strength indication (RSSI) value of the downlink packet. The wireless station then applies open-loop link adaptation and determines a modulation and coding scheme (MCS) based on the open-loop link metric and the RSSI value. The open-loop link adaptation scheme is especially suitable for smart meter/sensor networks as it reduces overhead and increases link capacity.
