Techniques for dynamic demodulation reference signal patterns for data transmission

An apparatus for demodulation reference signal (DMRS) transmission, comprising:

• a memory;
• and
• a processor communicatively coupled to the memory and configured to:
• receive, from a network entity, an uplink transmission configuration indication including a DMRS pattern for configuring DMRS transmission on an uplink communication channel, the DMRS pattern associated with one or more quality of service (QoS) characteristics, wherein the DMRS pattern corresponds to at least one of a first timeline-dependent DMRS pattern having one hybrid automatic repeat request (HARQ) interlace or a second timeline-dependent DMRS pattern having two or more HARQ interlaces;
• and
• transmit a DMRS to the network entity on the uplink communication channel in accordance with the DMRS pattern.

An apparatus for communication at a network entity, comprising:

• a memory;
• and
• a processor communicatively coupled to the memory and configured to:
• transmit, to a user equipment (UE), an uplink transmission configuration indication including a DMRS pattern for configuring DMRS transmission on an uplink communication channel, the DMRS pattern associated with one or more deployment characteristics, wherein the DMRS pattern corresponds to at least one of a first timeline-dependent DMRS pattern having one hybrid automatic repeat request (HARQ) interlace or a second timeline-dependent DMRS pattern having two or more HARQ interlaces;
• and
• receive a DMRS from the UE on the uplink communication channel in accordance with the DMRS pattern.
