Full duplex communication system using disjoint spectral blocks

摘要

The invention involves utilizing pieces of disjoint spectral blocks. In one embodiment, a frequency division duplex approach is used, where each spectral block is utilized solely for either uplink or downlink communications. In another embodiment, a time division duplex approach is used, where each spectral block is time divided and uplink and downlink communications are assigned to different time slots within the same spectral blocks. In another embodiment, a code division duplex approach is utilized, where uplink and downlink communications are assigned different codes/hopping patterns within a same spectral block.

1. A wireless transmit/receive unit comprising:
at least one antenna; an integrated circuit operatively coupled to the antenna; the integrated circuit and the at least one antenna are configured to receive in a first time interval a first orthogonal frequency division multiple access (OFDM) signal in a first frequency band over a first plurality of subcarriers and at a same time receive a second OFDM signal in a second frequency band over a second plurality of subcarriers; wherein the first frequency band and the second frequency band are in different Federal Communication Commission (FCC) spectral blocks; wherein the integrated circuit is further configured to recover data from the first OFDM signal and the second OFDM signal; and wherein the integrated circuit is further configured to be adaptively assigned frequency bands for reception on a time interval basis.
