Abstract
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. In one illustrative example, a network device can transmit, to a network entity, a capability report comprising a capability of the network device to support non-uniform time domain resource allocation of sensing reference signals (RSs). The network device can receive the sensing RSs for sensing one or more targets.
