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 a first example embodiment, a method may include transmitting, by a network entity, at least one radio resource control (RRC)-based cross link interference (CLI) measurement framework object configured for at least one user equipment (UE) CLI measurement. The method may further include receiving, by the network entity, at least one reporting message. The method may further include resolving at least one inter-UE CLI problem on a semi-dynamic time scale based upon reporting rates associated with RRC measurements and/or pre-defined behavior.

Abstract: Methods, apparatuses, and computer programs are provided for SRS for positioning resource overhead reduction in multi-RTT. A method for a UE includes receiving an initial configuration of a plurality of sounding reference signal for positioning resources; measuring a downlink positioning reference signal received from one or more cells; determining one or more transmission beams based on reception beams used for receipt of the downlink positioning reference signal from the one or more cells; wherein the determining of the one or more transmission beams comprises a reduction of at least one beam resource associated with a sounding reference signal for positioning; and transmitting an updated sounding reference signal for positioning configuration with information about the determined one or more transmission beams. Methods are also provided for a radio node and for an LMF.
