Techniques for communications on grating lobes

An apparatus for wireless communication at a first wireless device, 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, from a second wireless device, control signaling indicating that a message is to be transmitted using a first lobe of a directional beam, the first lobe of the directional beam being different from a second lobe of the directional beam that is used to simultaneously transmit the message to a third wireless device;
• determine a set of beamforming parameters for receiving the message from the second wireless device based at least in part on the control signaling indicating that the message is to be transmitted using the first lobe of the directional beam;
• and
• receive the message on the first lobe of the directional beam based at least in part on the set of beamforming parameters.

A non-transitory computer-readable medium storing code for wireless communication at a first wireless device, the code comprising instructions executable by a processor to:

• receive, from a second wireless device, control signaling indicating that a message is to be transmitted using a first lobe of a directional beam, the first lobe of the directional beam being different from a second lobe of the directional beam that is used to simultaneously transmit the message to a third wireless device;
• determine a set of beamforming parameters for receiving the message from the second wireless device based at least in part on the control signaling indicating that the message is to be transmitted using the first lobe of the directional beam;
• and
• receive the message on the first lobe of the directional beam based at least in part on the set of beamforming parameters.
