Envelope ratio method to improve beam hierarchy design

A method of wireless communication at a first wireless device, comprising:

• selecting a first beam for communication with a second wireless device from a first set of beams associated with a first beam level, the first beam being associated with a first children list, the first children list being associated with a first subset of beams of a second set of beams, the second set of beams being associated with a second beam level, each beam in the first subset of beams having an envelope area that intersects an envelope area of the first beam;
• selecting a second beam for communication with the second wireless device from the first subset of beams based on an envelope area of the second beam intersecting the envelope area of the first beam;
• and
• communicating with the second wireless device through at least one of the selected first beam or the selected second beam.

An apparatus for wireless communication at a first wireless device, comprising:

• means for selecting a first beam for communication with a second wireless device from a first set of beams associated with a first beam level, the first beam being associated with a first children list, the first children list being associated with a first subset of beams of a second set of beams, the second set of beams being associated with a second beam level, each beam in the first subset of beams having an envelope area that intersects an envelope area of the first beam;
• means for selecting a second beam for communication with the second wireless device from the first subset of beams based on an envelope area of the second beam intersecting the envelope area of the first beam;
• and
• means for communicating with the second wireless device through at least one of the selected first beam or the selected second beam.

A non-transitory computer-readable medium storing computer executable code at a first wireless device, the code when executed by a processor causes the processor to:

• select a first beam for communication with a second wireless device from a first set of beams associated with a first beam level, the first beam being associated with a first children list, the first children list being associated with a first subset of beams of a second set of beams, the second set of beams being associated with a second beam level, each beam in the first subset of beams having an envelope area that intersects an envelope area of the first beam;
• select a second beam for communication with the second wireless device from the first subset of beams based on an envelope area of the second beam intersecting the envelope area of the first beam;
• and
• communicate with the second wireless device through at least one of the selected first beam or the selected second beam.
