Abstract: Spatial and antenna information of a UAV is determined. Using at least the spatial and antenna information, a set of candidate transmission-reception beam pairs is determined, each pair between one of a set of one or more antenna panels in the UAV and one of multiple TRPs, wherein one or more of the multiple TRPs comprises includes a receiver-only antenna panel that is oriented upward. Beam sweeping is configured to be performed for the set of candidate transmission-reception beam pairs. Based on results of the beam sweeping, a transmission-reception beam pair of the set of candidate transmission-reception beam pairs is selected to be used for uplink communication(s) from the UAV to a determined TRP in the determined best transmission-reception beam pair. The UAV may send the spatial and antenna information toward a wireless communication network including the multiple TRPs, and may send this periodically or based on thresholds.

Abstract: There are provided a method, comprising monitoring if a predefined reference signal is decoded from a received signal, wherein the received signal is received at a predetermined resource element defined by a symbol time and a frequency range; informing a control device on receipt of an interfering pulsed signal if the reference signal is not decoded from the received signal; and a method, comprising monitoring if a total received power on a frequency range oscillates in time during RSRP cannot be calculated in a time period, wherein the frequency range and the time period are allocated to exclusively receiving reference signals; informing a control device on receipt of an interfering pulsed signal if the total received power oscillates in time.
