Method and apparatus for configuring a triggering condition of a beam failure event and a communication system. The method includes: a network device configures a UE with one or more control channel monitoring groups, so that when the UE detects that all beams to which a monitoring group corresponds fail in transmission, the UE reports beam failure event of the monitoring group fails in transmission; wherein, each monitoring group corresponds to one or more pieces of downlink control information (DCI). By configuring regarding the triggering conditions of the beam failure events, detection and report of beam failure in more complex scenarios may be supported, such as a scenario where one piece of DCI is transmitted in multiple control resource sets, and a scenario where multiple pieces of DCI are transmitted in one control resource set, etc.

In certain embodiments, a system for transmitting (electromagnetic or acoustic) wave-based signals towards a target includes a plurality of transceivers and a controller. Each transceiver transmits a probe signal towards the target and receives an associated backscatter signal corresponding to reflection of the probe signals from the target. The controller determines, for each transceiver, a Doppler frequency shift and a time delay, modifies each associated backscatter signal based on the corresponding Doppler frequency shift and time delay to generate an associated motion-compensated backscatter signal, and applies time reversal (TR) processing to each motion-compensated backscatter signal to generate an associated motion-compensated TR signal. Each transceiver transmits towards the target a transmission signal based the associated motion-compensated TR signal. In communications systems, the transmission signals are data-modulated versions of the motion-compensated TR signals. In radar and sonar systems, the transmission signals are the motion-compensated TR signals.
