BEAM SWEEP BASED RANDOM ACCESS MSG 3 AND MSG 4

摘要

A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a first random access message to a serving cell. The UE receives a second random access message from the serving cell, in response to the first random access message. The UE transmits a third random access message to one or more transmission reception points of the serving cell in a beam sweep pattern for reception on multiple beams and using resources based on at least one of a beam pool index or a TRP index.
