| 摘要 |
The invention concerns a method for performing adaptive subcarrier allocation to a mobile terminal (T 1 -T 4 ) for OFDM or FDM transmission in a multi cell network (CN), whereby transmit powers of base stations (BS 1 -BS 8 ) are estimated, channel transfer functions are calculated based on measurements in the mobile terminal (T 1 -T 4 ) of pilots transmitted from base stations (BS 1 -BS 8 ), the transmit powers are weighted with the channel transfer functions, a signal power and an interference power received in the mobile terminal (T 1 -T 4 ) are estimated based on said weighted transmit powers, a signal to interference ratio is estimated based on the estimated signal and interference power received in the mobile terminal (T 1 -T 4 ), and the adaptive subcarrier allocation is based on the signal to interference ratio of the subcarriers experienced by the mobile terminal (T 1 -T 4 ), a base station (BS 1 -BS 8 ), a mobile terminal (T 1 -T 4 ) and a multi cell network (CN) therefor.
