Patent ID: 11283499

Abstract:
A method performed by a first communication device operating in a wireless communications network. The first communication device obtains a set of correspondences associating: i) each set (ωi) of a plurality of sets of antenna weights (ω1 . . . ωi) having been sent by a third communication device in response to having received a respective set (RSsi) of a plurality of sets of radio signals (RSs1 . . . RSsi) from a set of antenna ports in a second communication device, with ii) a respective direction of transmission (di) between the second communication device and the third communication device. The respective direction is relative to an orientation (αi) of the second communication device. The respective direction of transmission (di) is a selected direction of transmission (di,αi). The first communication device then initiates transmission of a new radio signal, based on the obtained set of correspondences.
