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: The disclosure presents a method and system for enabling the monitoring of more than one propagation link (PL) between two transceivers, such as a fifth-generation (5G) broadband cellular base station (gNB) and user equipment (UE). The PL can represent a radiation pattern emitted by a MIMO antenna port. The monitoring can capture and record PL quality parameters and associate them to a PL index (PLI). The process can periodically cycle through the set of available PLs and select a best fit PLI configuration. The best fit PLI can be one that satisfies a link quality threshold and PL efficiency thresholds. The selected PLI can be communicated to both transceivers using parameter containers added to conventional control signals. Data messages communicated between the transceivers can utilize the selected best fit PLI configuration.

Abstract: Aspects and embodiments relate to an apparatus and method for performing antenna panel management. There is provided an apparatus comprising: means for obtaining signal reception information related to at least one downlink signal received by a user equipment using at least one reception antenna panel of a plurality of selectively-activatable antenna panels; means for determining an indication of effective power radiatable to the network node from which the downlink signal is received, based on the signal reception information related to the at least one downlink signal received by that to antenna panel for each of the plurality of selectively-activatable antenna panels which is configurable to transmit a signal to a network node from which the downlink signal is received; means for calculating an indication of power consumption associated with the indication of effective power radiatable to the network node for each of the plurality of selectively-activatable antenna panels; and means for selecting and configuring at least one of the selectively-activatable antenna panels to be used for transmission of a signal to a network node from which the downlink signal is received in response to the calculated indication of power consumption. Aspects support appropriate power efficient operation of a communication apparatus, for example by allowing for differentiated uplink and downlink antenna panel selection, which can enable apparatus power saving, whilst minimising performance loss, or incurring no significant performance loss.

Abstract: An apparatus for use by a UE configured to conduct a communication in a communication network. The apparatus is configured to receive and process signals from the communication network via signal receiving portions, wherein one of the signal receiving portions is a serving cell signal receiving portion used for connecting to the communication network via a serving cell, and another of the signal receiving portions is a non-serving cell signal receiving portion being not used for connecting to the communication network. A signal receiving portion specific offset value is obtained for each of the signal receiving portions. Signal quality values for signals received by the signal receiving portions from the communication network are measured, wherein the cells include the serving cell. A measurement report is sent to the communication network on the basis of the results of the signal quality measurements and the offset values for the signal receiving portions.
