Techniques for intra-message antenna selection diversity

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

• receiving, from a second UE, a first portion of a scheduled message within a time interval for the scheduled message, the first portion corresponding to a first antenna element of the second UE based at least in part on an intra-message antenna diversity configuration, the intra-message antenna diversity configuration indicating a plurality of antenna elements available for transmission of the scheduled message, the plurality of antenna elements including the first antenna element;
• receiving, within the time interval for the scheduled message, at least a second portion of the scheduled message corresponding to a second antenna element of the second UE that is different from the first antenna element based at least in part on the intra-message antenna diversity configuration, the plurality of antenna elements including the second antenna element;
• and
• decoding the first portion and the second portion of the scheduled message according to the intra-message antenna diversity configuration.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit a first portion of a scheduled message within a time interval for the scheduled message using a first antenna element of the UE based at least in part on an intra-message antenna diversity configuration for the UE, the intra-message antenna diversity configuration indicating a plurality of antenna elements available for transmission of the scheduled message, the plurality of antenna elements including the first antenna element;
• and
• transmit, within the time interval for the scheduled message, at least a second portion of the scheduled message using a second antenna element of the UE that is different from the first antenna element based at least in part on the intra-message antenna diversity configuration, the plurality of antenna elements including the second antenna element.
