Abstract
There is a provided a method for managing a multiple frequency assignment using a terminals RX performance in an orthogonal frequency division multiple access (OFDMA) wireless regional area network (WRAN) system, including: a) measuring a bit energy/noise power spectral density (Eb/No) and a received signal strength indicator (RSSI) which are received in the terminal; b) informing the measured Eb/No and RSSI of a base station; c) calculating a round trip delay (RTD) in the base station; d) determining a terminal performance level based on the measured Eb/No, RSSI and the calculated RTD; and e) determining a frequency channel and modulation scheme based on the determined performance level.
