Abstract
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network device can configure resources comprising a first Orthogonal Frequency-Division Multiplexing (OFDM) component for sensing and a second OFDM component for communication. The first OFDM component includes a second sensing symbol and a first sensing symbol includes a cyclic shifted prefix of the second sensing symbol. The network device can transmit, towards a target object, a sensing signal in the first OFDM component of the resources.
