摘要： Methods, systems, and devices for sidelink wireless communications are described in which multiple resource pools are available for sidelink communications. Each resource pool may include a set of frequency domain resources, a set of time domain resources, and one or more subsets of available spatial resources. A transmitting user equipment (UE) may select a first spatial resource of a first resource pool for the sidelink communication, and determine a demodulation reference signal (DMRS) pattern for the sidelink communications based on the selected first spatial resource of the first resource pool. The transmitting UE may then transmit the sidelink communication and DMRS to a receiving UE using the first spatial resource of the first resource pool. The receiving UE may identify the DMRS and use the DMRS to demodulate the sidelink communication of the transmitting UE.
