Abstract (en)

[origin: WO2020091637A1] A method by a first network node (101), for handling directions of receiver beam scanning by an antenna array in a first radio network node (111). Both nodes operate in a wireless communications network (100). The first network node (101) determines (503), out of a set of directions in which the first radio network node (111) is capable of beam scanning, a subset of directions of beam scanning having a probability of detection above a threshold, of a signal received from a first wireless device (131). The determining (503) is based on data obtained from previous attempts of positioning one or more second wireless devices (132) using at least some of the directions. The first network node (101) also initiates (504) providing, to at least one of: the first radio network node (111) and a second network node (102) operating in the wireless communications network (100), an indication of the determined subset.
