Techniques for performing beamforming based on zones

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

• transmitting, to a second wireless device, a first indication of a set of zones to which the second wireless device is configured to relay one or more messages from the first wireless device;
• transmitting, to the second wireless device, a second indication of a set of beams of the second wireless device associated with a corresponding zone of the set of zones, wherein the set of beams is configured to serve the corresponding zone;
• and
• receiving an additional indication of an updated set of beams from the second wireless device, wherein the updated set of beams is associated with the corresponding zone of the set of zones based at least in part on relaying by the second wireless device of communications from the first wireless device to the corresponding zone.

An apparatus for wireless communications, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a first indication of a set of zones to which a first wireless device is configured to relay one or more messages;
• receive a second indication of a set of beams of the first wireless device associated with a corresponding zone of the set of zones, wherein the set of beams is configured to serve the corresponding zone;
• relay communications to the corresponding zone using at least one beam of the set of beams based at least in part on the communications being for the corresponding zone or for a second wireless device located in the corresponding zone;
• identify one or more spatially correlated beams associated with the at least one beam of the set of beams;
• and
• relay the communications to the second wireless device using the one or more spatially correlated beams and the at least one beam of the set of beams.
