The increase of antennas can greatly improve the performance of MIMO systems, in the meanwhile, the precise channel state information is difficult to obtain since the channel matrix of massive MIMO is much more complex than the traditional one. In this paper, we propose a limited feedback strategy named hybrid limited feedback with selective eigenvalue information (HLFSEI), which jointly considers...
In this paper, we investigate joint user pairing and resource allocation under the practical constraints in single-carrier frequency-division multiple access (SC-FDMA) LTE uplink systems. We first introduce a joint optimal algorithm based on branch-and-bound search as a benchmark. To reduce complexity, we divide the joint optimization problem into two subproblems: user pairing and resource allocation...
