Abstract
A method of maintaining a communication link between a network node and a mobile node of a communications network comprises providing at least two downlink transmission beams (A to D) and designating a first of the at least two beams as a primary transmission beam (e.g. B). The beams are used in accordance with a schedule. Received signal quality or signal strength measurements are taken at the mobile node and signaled to the network node. A quality of link on the primary transmission beam (e.g. B) and at least one other of the at least two transmission beams (e.g. A, C) is determined from the measurements signaled from the mobile node to the network node and the quality of link for the beams is compared to provide a comparison and the schedule varied in accordance with the comparison.
