Aspects described herein relate to obtaining an indication of a comb pattern including a collection of non-contiguous time resource locations for transmitting a radar signal that includes a data channel communication, and one of transmitting, using the comb pattern, the radar signal to one or more other UEs over sidelink shared channel resources, or receiving, using the comb pattern, the radar signal from one or more other UEs over the sidelink shared channel resources. Other aspects relate to configuring the UEs with the comb pattern.

Disclosed are systems and techniques for wireless communications. For instance, a first network device for wireless communications may include at least one memory comprising instructions and at least one processor coupled to the memory. The at least one processor may be configured to generate a sidelink synchronization block (S-SSB), the S-SSB including at least two sidelink primary synchronization signal (SPSS) symbols and transmit, to a second network device, the generated S-SSB.
