Abstract
The invention relates to a radio unit selecting method and a frame setting method, and provides a radio unit selecting method used for a base station including a digital unit in a mobile radio backhaul network for a highly moving object carrying a vehicle terminal. When the first radio unit communicates with the vehicle terminal by utilizing CP of the first length among multiple radio units, the base station measures the distance between the vehicle terminal and the first radio unit. If the distance is smaller than a first threshold, the base station selects a second radio unit to be moved among the rest radio units in the multiple radio units. Moreover, the length of CP used by the first radio unit and the second radio unit is set by the base station to the third length between the secondlength and the first length. If the signal intensity of the first radio unit is smaller than a second threshold, the CP used by the second radio unit is set as the first length by the base station.
