1. A method for wireless communications at a first wireless device, comprising:
receiving, from a network device, configuration signaling that configures a set of sidelink resources comprising a plurality of slots within a subcarrier,
wherein at least a subset of the slots each comprise a respective first set of symbols allocated to a physical sidelink shared channel (PSSCH) and a respective second set of symbols after the respective first set of symbols, and wherein the respective second set of symbols is allocated to one or more types of reference signals;
transmitting, to a second wireless device and based at least in part on the configuration signaling, a data within the respective first set of symbols of a slot included in the subset of the slots and allocated to the PSSCH;
selecting at least a subset of resources within the respective second set of symbols of the slot for transmission of a reference signal of one or more types of reference signals based at least in part on an identifier associated with the first wireless device; and
transmitting, to the second wireless device and based at least in part on the configuration signaling, the reference signal via the at least subset of resources, wherein the slot does not include any symbol allocated to a physical sidelink feedback channel (PSFCH).
