Facilitating signaling and transmission protocols for enhanced beam management for initial access

A base station device, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• receiving, from a mobile device, a first message indicating first beam information for a selected first beam of beams associated with the base station device, wherein the first message is a first message of a random access channel procedure that is received by the base station device, and wherein the random access channel procedure is employed to facilitate a transfer of the mobile device from an idle state to a connected state;
• and
• receiving, from the mobile device, a second message indicating second beam information for a selected second beam of the beams associated with the base station device.

A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor of a mobile device, facilitate performance of operations, comprising:

• facilitating transmitting a first message indicating first beam information for a selected first beam of beams associated with a base station device, wherein the first message is part of a random access channel procedure;
• facilitating transmitting a second message indicating second beam information for a selected second beam of the beams associated with the base station device, wherein the selected second beam is an alternative to the selected first beam for transmission of downlink data to the mobile device from the base station device;
• and
• receiving, from the base station device, data comprising at least one of:
• receiving the data via the selected second beam instead of the selected first beam, receiving the data resulting in a same content of the data being transmitted via the selected first beam and the selected second beam, or receiving the data on a third beam.
