Which of the following channels is not involved in NR random access of a UE?

APDCCH

BPRACH

CPUSCH

DPUCCH

Show Suggested Answer

Suggested Answer: C

In 5G NR, the random access procedure is used by a UE to establish a connection with the base station. The channels involved in the NR random access of a UE are:

1. PDCCH (Physical Downlink Control Channel): The PDCCH is used by the base station to transmit control information to the UE, such as scheduling assignments and uplink grants.

2. PRACH (Physical Random Access Channel): The PRACH is used by the UE to transmit the random access preamble to the base station.

3. PUCCH (Physical Uplink Control Channel): The PUCCH is used by the UE to transmit control information to the base station, such as uplink scheduling requests and HARQ feedback.

4. PUSCH (Physical Uplink Shared Channel) is not involved in NR random access of a UE, it is a shared channel used to transmit the uplink data and control information.

Wait, are you sure about PUCCH? I thought it had a role in access too.

I believe PUCCH is used for uplink control, so it might not be part of the random access process.

I’m a bit confused about PUSCH and PUCCH; I feel like one of them might not be involved, but I can’t recall which.

I think the answer might be PDCCH since it’s mainly for control information, but I’m not entirely sure.

Okay, I remember learning about the PUCCH being used for control signaling, so that's probably not the right answer. I'll go with B, PRACH.

The PRACH is definitely involved, so it's not that one. I'm leaning towards option C, PUSCH, as the correct answer.
