Abstract: In a communication device that includes an antenna array including multiple antennas, a method and apparatus is provided for determining whether to employ an antenna array beamforming technique. The communication device determines a bearing from the communication device to the communication unit and a direction of arrival for a signal received from the communication unit by the communication device via each of the multiple antennas. In addition, the communication device determines a distance from the communication device to the communication unit, and also determines multiple signal quality metrics based on multiple signals received by the communication device from the communication unit. The communication device then determines whether to employ an antenna array beamforming technique based on any one or more of the determined bearing and the determined direction of arrival, the determined distance, or the determined signal quality metrics.
