There are the same physical frequency points between them. A cell can support one main frequency band and can support multiple equal frequency bands, and these equal frequency bands and the main frequency band of the cell have coincident physical frequency points, so that even if the terminal does not support the main frequency band when supporting the equivalent frequency band, It is also possible to access or cut into the cell to make full use of the cell resources.
