Channel feedback is essential for frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) systems to realize precoding and power allocation. Traditional codebooks for channel feedback, where the required number of feedback bits is proportional to the number of base station (BS) antennas, can not scale up with massive MIMO due to the large number of BS antennas. To solve this...
Nonorthogonal multiple access (NOMA) with successive interference cancellation is considered as one of the most promising schemes in multi-user access wireless networks. Based on the principles of NOMA and full-duplex (FD) communications, this paper proposes a novel FD-aided cooperative NOMA (FD-NOMA) scheme to optimize the maximum achievable rate region. Since self-interference often exists in FD...
