1. An apparatus comprising:a memory comprising instructions; and
a processor in communications with the memory, wherein the processor is configured to execute the instructions to:
determine a reference signal received power of user equipment (UE);
in response to determining that the reference signal received power is less than or equal to a threshold, determine that the UE supports
sending a physical random access channel,
receiving a random access response message,
sending a random access response acknowledgment message, and
receiving a contention resolution message; and
in response to determining that the reference signal received power is above the threshold,
determine that the UE supports sending the physical random access channel, and receiving the contention resolution message, and
determine that the UE does not support sending the random access response acknowledgment message and receiving the random access response message.
