Abstract:
A method of determining a beam for use in wireless communication is disclosed. The method is performed in a communication device comprising a digital receiver and an analog receiver. The method comprises receiving signaling on an active antenna port by using the digital receiver, measuring power of one or more beams received at one or more of a respective currently inactive antenna ports by using the analog receiver, and determining, the beam for use in the wireless communication by comparing received power of a beam received at the active antenna port to the power of the one or more beams received at the one or more respective currently inactive antenna port, and determining the beam for use to be the beam having the highest received power. A communication device, computer program and computer program products are also disclosed.
