1. A method of wireless communication at a user equipment (UE), comprising:
generating a scheduling request to request to transmit at least one of data or control information on a sidelink channel, wherein the generating the scheduling request comprises determining a preamble based on a root Zadoff-Chu sequence, wherein the scheduling request comprises the preamble, and the preamble is transmitted on a second set of resources dedicated to feedback; and
transmitting, to another UE, the scheduling request on resources of a channel configured to carry feedback responsive to transmissions on the sidelink channel, wherein the channel is configured with a first set of resources dedicated to scheduling requests and the second set of resources dedicated to feedback, and the first set of resources does not overlap with the second set of resources.
