Title: FIRST COMMUNICATION DEVICE AND METHODS PERFORMED THEREBY FOR MANAGING BEAMFORMING BY A SECOND COMMUNICATION DEVICE FOR TRANSMISSION OF A SIGNAL
Abstract:
Method performed by a first communication device (101) for managing beamforming by a second communication device (102) for transmission of a signal. The first and second communication devices operate in a wireless communications network (100) comprising a zone (120) wherein a radio frequency electromagnetic field strength is required by a regulation to be below a threshold. The first communication device (101) adjusts (201) one of: an output power and a beam shape in the beamforming. The adjusting (202) is such that the radio frequency electromagnetic field strength in the zone (120) for the output power and the beam shape in the beamforming is below the threshold. The first communication device (101) initiates transmission (202) of the signal to a third communication device (103) operating in the wireless communications network (100) using beamforming with the adjusted at least one of: output power and beam shape.
