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 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, wherein 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 further comprises a device identification message; and
in response to the receiving the beam information, facilitating transmitting, by the base station device 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 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, 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 another transmitted message of the random access channel procedure. - View Dependent Claims (11, 12, 13, 14, 15)
