| 摘要 |
The invention applies DFT-spread-OFDMA which is proposed for the 3GPP LTE uplink. The core of the invention is that we use a cyclic frequency shift operation over part of the bandwidth spanned by the IFFT. Furthermore, the cyclic frequency shift enables efficient inter-cell interference coordination in case neighbouring cells hop with the same pattern and different initial offsets. Equivalent operation may be performed in the time domain. |
