Abstract

The disclosure relates to methods, devices, and computer programs in mobile communications. More specifically, the proposed technique relates to beam quality reference signals transmitted by the network for use by wireless devices to measure the quality of neighbor cells or beams for mobility purposes. In particular the disclosure relates to a method, performed in a wireless communication system for scheduling beam quality measurement signals to be transmitted from one or more access points 20 to a plurality of wireless devices 10. The method comprises obtaining S1, for each of the plurality of wireless devices 10, information defining time periods when the transmission of beam quality measurement signals from the one or more access points 20 to the plurality of wireless devices 10 is to be performed and obtaining S2, for each of the plurality of wireless devices 10, candidate beams 40 for transmission of beam quality measurement signals from the one or more access points to the wireless device. The proposed methods further comprises scheduling S5 common beam quality measurement signals, usable by at least two of the plurality of wireless devices 10, are scheduled during overlaps o…
