Abstract
Aspects of the present disclosure relate to wireless communications and, more particularly, to beam refinement during a RACH procedure. A NB may receive a message via a first beam from a UE as part of a RACH procedure and may transmit at least one signal for beam refinement during the RACH procedure. A UE may transmit, to a NB, a message via a first beam as part of a RACH procedure and may receive, from the NB, at least one signal for beam refinement during the RACH procedure. Any directional signal beam may be used for beam refinement as described herein.

A method for wireless communication by a node B (NB), comprising:
- receiving a message via a first beam from a user equipment (UE) as part of a random access channel (RACH) procedure;
- and
- transmitting at least one signal for beam refinement during the RACH procedure.
A method for wireless communication by a user equipment (UE), comprising:
- transmitting, to a node B (NB), a message via a first beam as part of a random access channel (RACH) procedure;
- and
- receiving, from the NB, at least one signal for beam refinement during the RACH procedure.
