Abstract: Example embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage medium for beamlock on a plurality of antenna arrays. In a method, a first apparatus receives a beamlock message from a second apparatus. The beamlock message indicates that one or more transmitting beams are to be locked on a first list of antenna arrays and/or one or more receiving beams are to be locked on a second list of antenna arrays. Based on the beamlock message, the first apparatus performs beamlock of the one or more transmitting beams and/or the one or more receiving beams.

Abstract: Abstract: Disclosed is a method comprising increasing an antenna isolation between a first antenna panel and a second antenna panel by adjusting a radiation pattern associated with the first antenna panel and/or with the second antenna panel (1501). A first signal is then received via the first antenna panel and a second signal is transmitted via the second antenna panel substantially simultaneously (1502).

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: According to an aspect, there is provided an apparatus for a radio frequency front end of a beamforming transmitter or transceiver. The apparatus comprises a dual-polarized antenna element (222) for reception of electromagnetic waves transmitted by an antenna array (221) of the radio frequency front end and subsequently reflected from at least one obstruction. The dual-polarized antenna element comprises first and second feed points (223, 224) for reception of a first polarization and of a second polarization. The apparatus further comprises a switch for switching between reception of the first polarization via the first feed point and the second polarization via the second feed point.
