22 Claims

1. A user equipment (UE) configured for wireless communication, comprising:

memory comprising computer-executable instructions; and

one or more processors, individual or collectively, configured to execute the computer-executable instructions and cause the UE to:

transmit, to a network entity, a physical random access channel (PRACH) preamble in a random access channel (RACH) occasion (RO) within a RACH slot;

generate a random access radio network temporary identifier (RA-RNTI) based, at least in part, on the RO in which the PRACH was transmitted and whether a configured number of ROs exceeds RO capacity of one or more configured RACH slots defined within a reference slot; and

use the RA-RNTI to process a random access response (RAR) message transmitted from the network entity in response to the PRACH preamble.
