CONTENTION-FREE CONCURRENT PHYSICAL RANDOM ACCESS CHANNEL TRANSMISSIONS

摘要

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may transmit a first physical random access channel (PRACH) transmission that includes a first random access (RA) preamble to a base station. The apparatus may determine whether to transmit to the base station a second PRACH transmission that is concurrent with the first PRACH transmission in time, wherein the second PRACH includes a second RA preamble. The apparatus may transmit, to the base station, the second PRACH transmission that includes the second RA preamble when the second PRACH transmission is determined to be transmitted. The first RA preamble and the second RA preamble may be different, and the first RA preamble and the second RA preamble may be concurrently transmitted in a same PRACH occasion or in different PRACH occasions that overlap in time.
