Abstract

There is provided mechanisms for adaptive beamforming. A method is performed by a first network device. The method comprises acquiring beamforming information indicating spatial directions in which an identification signal is to be transmitted. The method comprises transmitting the identification signal in a transmission pattern using directional beams in the spatial directions towards second network devices. The identification signal is transmitted such that the identification signal occupies a larger portion of communications resources when transmitted in spatial directions with high second network device presence than in spatial directions with low second network device presence.
