FIELD

The subject matter herein generally relates to wireless communications, and more particularly, to a method and an apparatus for beamforming selection in multi-cell networks.

BACKGROUND

In multi-cell networks, users at the cell edge are susceptible to interference from neighboring signals, so beamforming techniques can be used to increase the signal-to-noise ratio (SNR) of user equipment at the cell edge.

The selection of beamforming technique used for downlink transmission directly affects the communication quality between a base station and user equipment. Conventional beamforming techniques use base station scanning to determine an optimal beam vector, which takes a lot of time and requires more extensive information through communication. Therefore, signal overload and computational complexity will increase with the number of base stations. Quickly providing users with an accurate and suitable beamforming technique is problematic.
