Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of services in future life, the 3GPP international standards organization has started to develop 5G for this purpose. When NR is deployed early, complete NR coverage is difficult to obtain, so typical network coverage is wide area LTE coverage and islanding coverage mode of NR. In the NR discussion, it is proposed that the RF bandwidth of the UE can be adjusted according to the actual throughput of the UE.
Therefore, the 5G UE finds an initial frequency point and a channel bandwidth through frequency search in the 5G cell, and resides in the cell if the signal condition is satisfied. And accessing the next network from the frequency point and the corresponding bandwidth. Generally, the frequency point searching process of the UE is from high to low of the 5G frequency point or from low to high, so that the UE is easily concentrated on two ends of the wideband carrier for camping. More resident users are present at the early two ends, resulting in a larger load for initial access.

the second communication unit is specifically configured to send the RRC release message to the UE.
24. The network device of claim 23, wherein the network device further comprises:
a second processing unit, which adds the BWP list as BWP information to the system broadcast when determining that the UE needs to perform BWP reselection;
and the second communication unit is used for sending system broadcast.
25. The network device of claim 24, wherein the BWP list comprises at least one BWP, and priority information and load information corresponding to each BWP.
26. The network device of any of claims 23-25, wherein the BWP information further comprises at least one of:
frequency point information of BWP, bandwidth information, SSB configuration information, CSI-RS configuration information, and indication information indicating whether system broadcasting needs to be re-read.
27. A UE, comprising: a processor and a memory for storing a computer program capable of running on the processor,
wherein the processor is adapted to perform the steps of the method of any one of claims 1-9 when running the computer program.
28. A network device, comprising: a processor and a memory for storing a computer program capable of running on the processor,
wherein the processor is adapted to perform the steps of the method of any one of claims 10-13 when executing the computer program.
29. A computer storage medium storing computer-executable instructions that, when executed, implement the method steps of any of claims 1-13.
