Frequency domain resource allocation indications for transform precoding in multiple transmit receive point deployments

An apparatus for wireless communications at a network entity, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, wherein the instructions are executable by the processor to:
• transmit an indication of a configuration of a first beam configuration and a second beam configuration;
• transmit a downlink control information message comprising a frequency domain resource allocation field indicating a first set of frequency resources associated with the first beam configuration, wherein a first number of frequency resources in the first set of frequency resources satisfies a first transform precoding threshold number of frequency resources;
• and
• receive a first uplink message using the first set of frequency resources according to the first beam configuration and a second uplink message using a second set of frequency resources according to the second beam configuration, wherein a second number of frequency resources in the second set of frequency resources satisfies a second transform precoding threshold number of frequency resources.

A method for wireless communications at a user equipment (UE), comprising:

• receiving an indication of a configuration of a first beam configuration and a second beam configuration;
