Claim of US Patent No. 10,461,814

1. A method for wireless networking comprising one or more Base Stations (BSs) with Nbs antennas; two or more Small Cells (SCs) in a range of a BS of said one or more BSs where a SC has Nsc antennas, uses Nsc1?Nsc antennas for communication with the BS and uses Nsc2?Nsc antennas for communication with one or more User Equipment (UEs); at the same time the BS transmitting Downlink (DL) signals to K SCs using a multi-user transmit beamforming (BE) in a frequency channel where K>1 and Nbs?KNsc1, based on evaluation of the BS-UE interferences and the SC-SC interferences using analysis of the deployment and path loss assessment, allocating frequency resources for the one or more SCs to simultaneously transmitting DL signals to one or more UEs in their ranges; and, at the same time the BS receiving Uplink (UL) signals from K SCs using the multi-user receive BF in a frequency channel where K>1 and Nbs?KNsc1, based on evaluation of the BS-UE interferences and the SC-SC interferences using analysis of the deployment and path loss assessment, allocating frequency resources for the one or more SC to simultaneously receiving UL signals from one or more UEs in their ranges;wherein the wireless networking further comprising choosing the number of antennas on the BS Nbs to be sufficiently larger than the total number of antennas for communicating with the BS on all the SCs served using the same frequency resource to match the throughput of the link between the BS and SCs with the sum throughput of the SCs.
