Abstract
A beamforming selection method of a first wireless communication node is disclosed. The method includes receiving first reference signaling, transmitted from a second wireless communication node using a first beamforming setting, generating a first channel estimate based on the first reference signaling, and transmitting, using a second beamforming setting, second reference signaling for reception by the second wireless communication node, wherein each coefficient of the second beamforming setting represents a complex conjugate of a corresponding component of the first channel estimate. In some embodiments, the method further includes iterating the receiving, generating, and transmitting steps until a stopping criterion is met. For example, the stopping criterion may include that a number of iterations performed equals a maximum number of iterations, and/or that a beamforming convergence criterion is met. Corresponding apparatus, wireless communication node and computer program product are also disclosed.
