Claim 10:
11. A method of wireless communication performed by a receiver user equipment (UE), comprising:
determining, for a first slot allocated for data reception over a sidelink between the receiver UE and a transmitter UE, a first set of demodulation reference signal (DMRS) patterns, wherein the first slot corresponds to a first slot format, and wherein the first set of DMRS patterns is associated with the first slot format based on
(i) presence or absence of orthogonal frequency-division multiplexing (OFDM) symbols for sidelink feedback specified by the first slot format, and
(ii) a subcarrier spacing (SCS), a frequency range, or both, of the sidelink;

receiving, from the transmitter UE, an index value indicating one of the first set of DMRS patterns;
determining the one of the first set of DMRS patterns indicated by the index value as a first DMRS pattern for the first slot; and
receiving, from the transmitter UE, DMRS in the first slot according to the first DMRS pattern,
wherein, in a case that the first set of DMRS patterns includes two different DMRS patterns, the index value is one of two different values that respectively represent the two different DMRS patterns included in the first set of DMRS patterns, and
wherein, in a case that the first set of DMRS patterns includes three different DMRS patterns, the index value is one of three different values that respectively represent the three different DMRS patterns included in the first set of DMRS patterns.
