MASSIVE MIMO MULTI-USER BEAMFORMING AND SINGLE CHANNEL FULL DUPLEX FOR WIRELESS NETWORKS

摘要

This invention presents a method and apparatuses for wireless networking comprising one or more BS with N_bs antennas; two or more SCs in the range of a BS where a SC has N_sc antennas, uses N_sc1≤N_sc antennas for communication with a BS and uses N_sc2≤N_sc antennas for communication with one or more UEs; at the same time a BS transmitting DL signals to K SCs using multi-user transmit BF in a frequency channel, a SC simultaneously transmitting DL signals to one or more UEs in its range using the same frequency channel; and, at the same time a BS receiving UL signals from K SCs using multi-user receive BF in a frequency channel, a SC simultaneously receiving UL signals from one or more UEs in its range using the same frequency channel. Furthermore, beamforming using antennas on the SCs is performed to reduce the inter-SC interferences.
