PCT NATIONAL PHASE APPLICATION
Published
Filed on 29 October 2024
Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first control signaling identifying a demodulation reference signal (DMRS) pattern that may be uniformly distributed in a time domain and a frequency domain. The DMRS pattern may include a first set of resource elements for the DMRS, a second set of resource elements for guard tones adjacent to and greater in frequency than the first set of resource elements, and a third set of resource elements for guard tones adjacent to and lower in frequency than the first set of resource elements. The UE may receive second control signaling that schedules a data signal to be communicated between the UE and a network node in a set of time-frequency resources. The UE may communicate the data signal according to the second control signaling and the DMRS according to the DMRS pattern.
