Abstract
A method for a network node of a cellular communication network is disclosed. The network node and at least some other network nodes of the cellular communication network are each adapted to support a plurality of beams of a signal beam-forming scheme and to communicate with a wireless communication device using at least one of the plurality of beams. The method comprises identifying one or more candidate beams, causing transmission of a reference signal on each of the candidate beams, causing reservation of an uplink resource of at least one of the candidate beams (wherein the uplink resources are for conveying a report from the wireless communication device, and wherein the report is indicative of a result of measurements of the reference signals), and causing the communication with the wireless communication device to use a target beam (wherein one of the candidate beams is selected as the target beam based on the conveyed report). A corresponding method for a wireless communication device is also disclosed, as well as a computer program product, respective arrangements for a network node and a wireless communication device, a network node and a wireless communication device.
