Classification: CPC H | IPC H

Claim 14:
15. The base station of claim 14, wherein the receiver is further configured to receive a receiving power and a signal interference noise ratio (SINR) of a reference signal from the user equipment wherein the receiving power and the SINR of the reference signal is calculated by using the data received on the second frequency band, by the user equipment; and
the processor is further configured to:
compare the receiving power and the SINR of the reference signal with a switching threshold, when any one of the receiving power and the SINR of the reference signal is smaller than the switching threshold, and
switch the current data transmission frequency band, from the second frequency band or from the cooperative transmission of the first frequency band with the second frequency band to the first frequency band, otherwise, to maintain the current data transmission band.
