Selective radiation of radio frequency (RF) reference beams in a wireless communications system (WCS) based on user equipment (UE) locations is disclosed. The WCS may include a radio node that communicates RF communications signals in a coverage area via RF beamforming. Thus, the radio node is required to periodically radiate a number of RF reference beams in different directions of the coverage area to help UEs to identify a best-possible RF beam(s). However, radiating the RF beams in different directions periodically can increase power consumption of the radio node, particularly when the UEs are concentrated at a handful of locations in the coverage area. In this regard, the radio node can be configured to selectively radiate a subset of the RF reference beams based on a determined location(s) of the UE(s) in the coverage area, thus making it possible to reduce computational complexity and power consumption of the radio node.

Selective radio frequency (RF) reference beam radiation in a wireless communications system (WCS) based on user equipment (UE) locations

Radio frequency (RF)-based ranging and imaging in a wireless communications circuit, particularly for a wireless communications system (WCS) is provided. The wireless communications circuit includes an antenna circuit configured to radiate an RF probing signal in a number of directions in a wireless communications cell and receives a number of RF reflection signals corresponding to the RF probing signal. A radar signal processing (RSP) circuit is configured to process the RF reflection signals to detect an obstacle(s) in the wireless communications cell and generate a surrounding image that includes the detected obstacle(s). By generating the surrounding image of the wireless communications cell, it may be possible to detect the obstacle(s) that was not accounded for in an initial deployment design. As a result, it may be possible to adjust a remote unit(s) incorporating the wireless communications circuit to improve RF coverage, throughput, and/or capacity in the wireless communications cell.
