Demodulation reference signal precoding in precoding resource block groups associated with subband full duplex configurations

A network node for wireless communication, comprising:

• memory;
• and
• one or more processors coupled with the memory and configured to cause the network node to:
• transmit a resource allocation that includes a set of physical resource blocks (PRBs) for a communication to be communicated in at least one precoding resource block group (PRG), the at least one PRG comprising a partial PRG associated with an edge of a subband of a subband full duplex (SBFD) configuration, wherein the communication includes a demodulation reference signal (DMRS) and a physical downlink data channel signal or a physical uplink data channel signal;
• and
• communicate a portion of the communication in the partial PRG based on a partial PRG rule associated with the partial PRG and based on a precoding associated with a PRG adjacent to the partial PRG.

A user equipment (UE) for wireless communication, comprising:

• memory;
• and
• one or more processors coupled with the memory and configured to cause the UE to:
• receive a resource allocation, associated with a subband full duplex (SBFD) configuration, that includes a non-contiguous set of physical resource blocks (PRBs), associated with two downlink subbands within a downlink bandwidth part, for a communication to be communicated in at least one precoding resource block group (PRG), wherein:
• the communication includes a demodulation reference signal (DMRS) and a physical downlink data channel signal or a physical uplink data channel signal,
• a precoding granularity is configured so that a corresponding precoder is applied to contiguous PRBs, and
• a control resource set (CORESET) associated with the two downlink subbands includes the non-contiguous set of PRBs and overlaps an uplink subband;
• and
• perform a wireless communication operation based on a precoding rule associated with the at least one PRG, wherein the precoding rule indicates that communication in the at least one PRG is allowed or not allowed.
