1. A high altitude platform station (HAPS) network device comprising:
a wireless antenna array configured to communicate with at least one user equipment (UE) located within a cell coverage area associated with the HAPS network device, the cell coverage area including a plurality of beam layers and a plurality of beams, each of the plurality of beam layers including at least one beam of the plurality of beams;
a memory storing computer readable instructions; and
processing circuitry configured to execute the computer readable instructions to cause the HAPS network device to,
determine beam layer information corresponding to the plurality of beam layers, the beam layer information including layer identifiers (ID) associated with each beam layer of the plurality of beam layers, and beam IDs associated with each beam included in each of the beam layers;
transmit the beam layer information to the at least one UE;
receive an autonomous beam switch request from the at least one UE in response to the transmitted beam layer information, the request including beam switch parameters;
determine a selected beam layer based on the beam switch parameters; and
enable communication with the at least one UE using the selected beam layer.
