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 op eration over part of the bandwidth spanned by the IFFT. Furthermore, the cyc lic frequency shift enables efficient inter-cell interference coordination i n case neighbouring cells hop with the same pattern and different initial of fsets. Equivalent operation may be performed in the time domain. |
