Abstract: An apparatus, method and computer program is described comprising: receiving, at a user device, a downlink reference signal from a communication node of a mobile communication system, wherein the downlink reference signal is received by one of a plurality of beams of a receiver of the user device in accordance with a configured beam alignment; determining whether to initiate beam switching to reconfigure the beam alignment at said receiver based, at least in part, on a signal power of the received downlink reference signal; and determining, in the event that beam switching is to be initiated, whether to initiate communication node assisted beam switching or non-communication node assisted beam switching.

Abstract: An apparatus and method for beam steering is disclosed. The apparatus comprises: a beam forming signal generator configured to generate a beam forming signal for applying to at least one of amplitude and phase shift circuitry associated with an antenna array to provide a radiation pattern. A determining means is provided that is configured to determine a signal strength of interfering signals received at the antenna array within a user equipment and to determine a dominant interfering ratio indicative of a strength of a strongest interfering signal relative to a strength of other interfering signals. A comparator is provided that is configured to compare the dominant interfering ratio to a predetermined ratio value and where the dominant interfering ratio exceeds the predetermined ratio value to generate a control signal for controlling the beam forming signal generator to generate a radiation pattern comprising a beam and at least one steered null.

Abstract: An apparatus comprising: an antenna array comprising a plurality of antenna elements configured for receiving multiple input multiple output (MIMO) signals. The antenna array comprises at least a first subpart of the antenna array comprising a first subsection of the plurality of antenna elements. A second subpart of the antenna array comprises a second subsection of the plurality of antenna elements. An alignment of the antenna elements in the second subpart deviates substantially by 30°-60° from an alignment of the antenna elements in the first subpart.

Abstract: A method comprises: determining, from an indication that an initial uplink beam between a user equipment and a network node is misaligned with respect to a downlink beam between the network node and the user equipment, at least one misalignment angle between the initial uplink beam and the downlink beam; and reconfiguring the uplink beam based on the misalignment angle to produce a reconfigured uplink beam.

Abstract: Systems, methods, apparatuses, and computer program products for GIS-NR beamforming for mmWave. For example, certain embodiments may provide for beam realignment, through which a serving network node may be able to re-position its beam towards a UE without the UE explicitly measuring and signalling to the network node the need for realignment. Instead of performing the traditional UE-based exhaustive beam search, the serving network node may proactively switch the beam in an attempt to track the UE movements. The serving network node may do this by corroborating information from two types of sources: 1) a set of neighbor mobile or fixed network nodes and 2) a geographic information system (GIS).
