Patent ID: 11848732

Abstract:
A method for wireless backhaul inter-node communication between a first backhaul node and a second backhaul node is provided. The method includes computing a beamforming weight matrix W; and the first backhaul node using the beamforming weight matrix W to transmit and/or receive data to and/or from the second backhaul node. The beamforming matrix W is computed as the inverse of a weighted channel estimate matrix (Formula I), such that W=(Formula II), where Ĥ is a channel estimate matrix and ρ is a weighting factor matrix such that (Formula III) where ρ has dimension Nrx by Ntx, where Nrx is the number of receive antennas and Ntx is the number of transmit antennas, where Ntx,=Nrx, and ρ is a scalar between 0 and 1, and where ∘ denotes a Hadamard matrix product.
