Question 1/39
In the contention-based random access procedure, which of the following is related to the time-frequency position of the PRACH used by the UE?
Correct Answer: B
BWP (Bandwidth Part) is related to the time-frequency position of the PRACH used by the UE in the contention-based random access procedure. According to the official Huawei documentation, the BWP consists of one or more contiguous frequency sub-bands of the PRACH and defines the time-frequency position of the PRACH used by the UE.
