Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may increase a transmission power for a physical sidelink shared channel (PSSCH) communication based at least in part on decreasing a transmission power for a physical sidelink control channel (PSCCH) communication. The UE may transmit the PSCCH communication using the decreased transmission power for the PSCCH communication and transmit the PSSCH communication using the increased transmission power for the PSSCH communication. Numerous other aspects are provided.

The present invention is particularly directed to a signal-quality determination device (300) that comprises a transceiver unit configured to provide a wireless beacon-request signal as a single-hop broadcast signal indicative of a request to any wireless communication device (312.1, 312.2, 340) within a single-hop distance from the signal-quality determination device and belonging or not to a wireless communication network 350 to which the signal-quality determination device belongs, to provide a respective beacon-response signal upon reception of the beacon-request signal, and to receive the beacon-response signals. The signal-quality determination device is configured to determine beacon signal-quality data (SQ) indicative of a received-signal quality, e.g. RSSI of the beacon-response signal, or a channel-state CSI of a respective wireless communication link. The signal-quality determination device is suitable for enabling a reduction of complexity in a radiofrequency based presence or movement sensing function.
