High-granularity precoder cycling with channel estimation

An apparatus for wireless communications, comprising:

• memory;
• and
• at least one processor of a network entity, the at least one processor coupled with the memory and configured to:
• transmit, via a first beam, first representations of a first symbol of a space-frequency block coded symbol pair using first resources of a plurality of resources and first representations of a second symbol of the space-frequency block coded symbol pair using second resources of the plurality of resources, wherein the plurality of resources are a plurality of time and frequency resources;
• and
• transmit, via a second beam, second representations of the first symbol using the second resources and second representations of the second symbol using the first resources of the plurality of resources,
• wherein across the plurality of resources, the first beam, and the second beam, each representation of the first symbol and each representation of the second symbol is precoded by a different respective precoder of a plurality of precoders.

A method for wireless communications at a wireless device, comprising:

• receiving first representations of a first symbol of a space-frequency block coded symbol pair using first resources of a plurality of resources and first representations of a second symbol of the space-frequency block coded symbol pair using second resources of the plurality of resources, the first representations of the first symbol and the first representations of the second symbol being transmitted via a first beam, wherein the plurality of resources are a plurality of time and frequency resources;
• and
• receiving second representations of the first symbol using the second resources and second representations of the second symbol using the first resources of the plurality of resources, the second representations of the first symbol and the second representations of the second symbol being transmitted via a second beam,
• wherein across the plurality of resources, the first beam, and the second beam, each representation of the first symbol and each representation of the second symbol is precoded by a different respective precoder of a plurality of precoders.
