In some aspects, a wireless communication device may map a code block to resources, of a physical shared channel, that are allocated for data-modulated demodulation reference signals (DMRSs) in which each of the resources carries both at least a portion of a DMRS sequence and data. The wireless communication device may transmit a communication, via the physical shared channel, that includes the code block that is mapped to the resources that are allocated for the data-modulated DMRSs.

Monostatic radar with progressive length transmission may be used with half-duplex systems or with full-duplex systems to reduce self-interference. The system transmits a first signal for a first duration and receives a first reflection of the first signal from a first object during a second duration. The system transmits a second signal for a third duration longer than the first duration and receives a second reflection of the second signal from a second object during a fourth duration. The system calculates a position of the first object and the second object based on the first reflection and the second reflection. The first signal, first duration, and second duration are configured to detect reflections from objects within a first distance of the system. The second signal, third duration, and fourth duration are configured to detect reflections from objects between the first distance and a second distance from the system.
