Frequency band switching method, apparatus, terminal device, communication node and computer readable storage medium

A terminal device, comprising:

• a memory, a processor, and a computer program stored on the memory and capable of running on the processor, wherein the computer program, when being executed by the processor, implements a frequency band switching method, wherein, the frequency band switching method comprises:
• determining whether an uplink operation frequency band needs to be switched according to transmission power information of a terminal device, when the uplink operation of the terminal device is performed in a first frequency band;
• performing, by the terminal device, beam scanning on a second frequency band to switched to;
• and
• switching, by the terminal device, to the second frequency band according to a result of the beam scanning.
