Facilitating signaling and transmission protocols for enhanced beam management for initial access
First Claim
1. A method, comprising:
- receiving, by a base station device comprising a processor from a mobile device, a message indicating first beam information for a selected first beam of beams associated with the base station device and indicating second beam information for a selected second beam of the beams, 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, wherein the receiving the message comprises receiving the message as a first message of a multi-step random access channel procedure, wherein the first message comprises a random access preamble and a device identification message, and wherein the random access preamble is employed to facilitate a transfer of the mobile device from an idle state to a connected state; and
in response to the receiving the beam information, facilitating, by the base station device, transmitting, to the mobile device, a random access channel response as a second message of the two step random access channel procedure.

Abstract
Enhanced beam management for a wireless communication system is provided. In one example, a method comprises: receiving, from a mobile device, a message indicating first beam information for a selected first beam of beams associated with the base station device, wherein the message is a first received message of a random access channel procedure; and receiving, from the mobile device, 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 wherein the second beam is indicated in the first message of a two-step random access channel procedure. Methods of signaling the second beam and/or transmission diversity approaches employing the first beam and/or the second beam are described.

10. 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, 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 wherein the second message is a second message of the random access channel procedure that is transmitted by the base station device. - View Dependent Claims (11, 12, 13, 14, 15)

16. 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, and wherein the random access channel procedure is employed to facilitate a handover of the mobile device; 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 wherein the second message is transmitted as part of the random access channel procedure; 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, wherein the third beam is a combination of the selected first beam and the selected second beam and is wider than the selected first beam and the selected second beam. - View Dependent Claims (17, 18, 19, 20)
