System and method for transmitting beam failure recovery request

A method of beam failure recovery operable at a scheduling entity, comprising:

• receiving a random access channel (RACH) preamble in a RACH procedure from a user equipment (UE);
• transmitting a RACH response to the UE;
• and
• receiving a radio resource control (RRC) connection request from the UE, wherein the RRC connection request indicates that the RACH preamble comprises a beam failure recovery request.

A method of beam failure recovery operable at a scheduling entity, comprising:

• assigning a random access channel (RACH) resource to a plurality of scheduled entities including a user equipment (UE) for conveying a beam failure recovery request (BFRR);
• and
• receiving, from the UE, the BFRR in a RACH procedure utilizing the assigned RACH resource;
• receiving, in the RACH procedure, a cell radio network temporary identity (C-RNTI) from the UE;
• and
• confirming the C-RNTI received from the UE corresponds to a C-RNTI stored in the scheduling entity.

A method of beam failure recovery operable at a user equipment (UE), comprising:

• receiving, from a scheduling entity, an assignment of a random access channel (RACH) resource that is assigned to a plurality of scheduled entities including the UE for conveying a beam failure recovery request (BFRR);
• and
• transmitting, to the scheduling entity, the BFRR in a RACH procedure utilizing the assigned RACH resource;
• transmitting, in the RACH procedure, a cell radio network temporary identity (C-RNTI) to the scheduling entity;
• and
• completing a beam failure recovery with the scheduling entity upon confirmation by the scheduling entity that the transmitted C-RNTI corresponds to a C-RNTI stored in the scheduling entity.
