Abstract:
This invention presents methods for MU-MIMO wireless communication systems comprising a BS with plural of antennas, either closely located or distributed; A plural of AFRs deployed over a coverage area, each AFR has N_BF≥1 BF antennas with a beam pattern facing the MU-BFer and N_UF≥1 UF antennas with a beam pattern facing UEs or downstream AFR(s); A channel estimation module for estimating the Total Channels between a plural of UEs and the BS with the AFRs in place; and, A MU-BFer that uses the estimates of the Total Channels to perform beamforming computations for transmitting and/or receiving multiple spatially multiplexed streams of signals to or from a plural of UEs using the same frequency resource.

Claim (Index 35):
A method for Multiple-Input-Multiple-Output (MIMO) communication comprising\n estimating total channel parameters comprising correlations and one or more of delay spreads or coherence bandwidth, Channel Quality Information (CQI), Channel Estimation Error (CEE) and User Equipment (UE) Speed Indication Information (SII) of the total channels of different UEs; selecting a part of the UEs into a group based on their total channel parameters such that it improves system performance when Amplify and Forward Relays (AFRs) are present, wherein the improved performance comprises one or more of Multi-User MIMO (MU-MIMO) beamforming, increased system throughput, reduced computational load, and reduced power consumption; allocating frequency resources to the group of UEs; computing precoding and/or detection matrix using total channel matrix of the UEs in the group on the allocated frequency resources; and performing MU-MIMO beamforming with the UEs in the group on the allocated frequency resources with AFRs present.
