| 摘要 |
<p>The invention concerns a method for performing adaptive subcarrier allocation to a mobile terminal (T1-T4) for OFDM or FDM transmission in a multi cell network (CN), whereby transmit powers of base stations (BS1-BS8) are estimated, channel transfer functions are calculated based on measurements in the mobile terminal (T1-T4) of pilots transmitted from base stations (BS1-BS8), the transmit powers are weighted with the channel transfer functions, a signal power and an interference power received in the mobile terminal (T1-T4) 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 (T1-T4), and the adaptive subcarrier allocation is based on the signal to interference ratio of the subcarriers experienced by the mobile terminal (T1-T4), a base station (BS1-BS8), a mobile terminal (T1-T4) and a multi cell network (CN) therefor.</p> |
