Techniques for low-complexity joint antenna group (jag) formation with analog beamforming of discrete antennas

An apparatus for wireless communications, comprising:

• a transceiver having a plurality of antennas;
• one or more memories;
• and
• one or more processors coupled to at least one of the one or more memories and configured to:
• receive, from a user equipment (UE), an indication for network assistance in forming one or more virtual antenna modules, the indication including UE hardware capability information;
• identify, based on the received indication including the UE hardware capability information, antenna beamforming information including the one or more virtual antenna modules, wherein each of the one or more virtual antenna modules forming an antenna grouping at the UE from one or both of a phase shifter or an amplitude control for each antenna element from multiple antenna elements associated with multiple antenna layers;
• and
• transmit, to the UE, an indication that includes the antenna beamforming information associated with multiple antenna elements across multiple antenna layers.

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

• receiving, from a network entity, an indication that includes antenna beamforming information associated with multiple antenna elements across multiple antenna layers;
• configuring one or both of a phase shifter or an amplitude control for each of the multiple antenna elements based on receiving the indication from the network entity to form one or more virtual antenna modules with each module including at least two antenna elements;
• and
• communicating, with the network entity, information using the one or more virtual antenna modules.
