Therefore, it is recommended that the radio frequency bandwidth of the UE can be adjusted according to the actual throughput of the UE. For this reason, the concept of BWP is introduced. The motivation for introducing BWP is to optimize the power consumption of the UE. For example, the rate requirement of the UE is very low.
