Abstract: To facilitate positioning a user device, the user device is configured to measure, per an antenna array, reference signals received from transmission-reception points and to check, whether a downlink reference signal from a transmission-reception point is received in a serving antenna array and in one or more non-serving antenna arrays with a first delay. A non-serving antenna array receiving the signal with the first delay is an alternative antenna array to the serving antenna array. When the serving antenna array is under a maximum permissible exposure event, the user device is configured to select, which one of one or more alternative antenna arrays and the serving antenna panel is to be used for transmitting at least a positioning signal to the transmission-reception point.

Abstract: To increase positioning accuracy, channel characteristics are determined taking into account receive filter response and transmit filter response. For example, upon receiving assistance data for positioning an apparatus, a transmit sequence is generated using the assistance data; and a combination of the transmit sequence is generated by combining the transmit sequence. Further, a receive filter response is determined, a transmit filter response is obtained, and a combined filter response is generated using the receive filter response and the transmit filter response. Reference signals received over a channel are measured by sampling them into a plurality of time-domain samples, and the channel is estimated from the plurality of time-domain samples using the combined filter response and the combination of the transmit sequence. Then, per channel characteristics, a value of the channel characteristics based on the channel estimated is determined.

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.
