1. A user equipment (UE), comprising:
memory; and
processing circuitry in communication with the memory and configured to:
select a sidelink resource for sidelink transmission; and
transmit the sidelink transmission on the selected sidelink resource, wherein the sidelink transmission includes an initial orthogonal frequency division multiplexing (OFDM) symbol, wherein the initial OFDM symbol is a copy of a second OFDM symbol, wherein the second OFDM symbol immediately follows the initial OFDM symbol, wherein the second OFDM symbol includes at least one of a physical sidelink shared data channel or a physical sidelink control channel, and wherein, when the sidelink transmission includes 6 symbols or 7 symbols, a second symbol and a sixth symbol of the sidelink transmission are demodulation reference signals (DM-RS).
