1. A method comprising:
receiving, by a first wireless user device, a radio resource control (RRC) signaling configuration indicating a sidelink (SL) identifier (ID) value;
determining, based on a least significant bit (LSB) part of a layer-2 ID, a layer-1 ID for SL communication, wherein layer-1 is a physical layer of a wireless communication system, wherein layer-2 is an upper layer of the physical layer, and wherein the upper layer comprises a medium access control (MAC) laver;
receiving, from a second wireless user device and based on the layer-1 ID, at least one data packet via a physical sidelink shared channel (PSSCH);
generating an orthogonal sequence for a physical sidelink feedback channel (PSFCH) format, based on:
the SL ID value; and
a cyclic hopping parameter; and
transmitting, to the second wireless user device and based on the orthogonal sequence, SL feedback control information (SFCI) via a PSFCH.
