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