At present, with the pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of business in the future, the 3GPP International Standards Organization has begun to develop 5G. In the early deployment of NR, complete NR coverage is difficult to obtain, so typical network coverage is wide-area LTE coverage and NR's island coverage model. In the NR discussion, it is recommended that the UE's RF bandwidth can be adjusted according to the actual throughput of the UE.

Therefore, the 5G UE finds the initial frequency and channel bandwidth through the frequency search in the 5G cell, and will stay if the signal condition is met. The next network access is also accessed from this frequency and the corresponding bandwidth. In general, the frequency search process of the UE is from the high to low or low to high of the 5G frequency, so that the UE can easily concentrate on both ends of the wideband carrier for camping. There are more resident users at both ends of the early stage, resulting in a larger initial load.
