1. A method comprising:
sending a request for a report on beamforming capability to a target user equipment;
receiving the report on the beamforming capability from the target user equipment;
allocating at least one positioning reference signal resource for use by the target user equipment based on at least the capability information included in the report, wherein the allocation of the at least one positioning reference signal resource includes one or more positioning reference signal resources for beam sweeping and one or more positioning reference signal resources with configured spatial relations, the one or more positioning reference signal resources for beam sweeping being allocated according to a number of beam directions not covered by the one or more positioning reference signal resources with configured spatial relations;
determining a beam sweeping rule based on the at least one positioning reference signal resource allocated for the target user equipment; and
sending the positioning reference signal resource allocation and the beam sweeping rule to the target user equipment.
