Abstract
A method of frequency utilization in mobile communication which is capable of realizing efficient frequency utilization in the case where widths of the uplink communication frequency bandwidth and the downlink communication frequency bandwidth are different in mobile communication is disclosed. Two pieces of carriers U1 and U2 among the uplink carriers U1 to U6 are selected as selected carriers, carriers U1 to U6 of the uplink bandwidth Wu and carriers D1,1 to D1,6 of the first downlink bandwidth Wd1 are set in one-to-one correspondence, the selected carriers U1 and U2 and carriers D2,1 and D2,2 of the second downlink bandwidth Wd2 are set in one-to-one correspondence, the communications are carried out by using D1,1 and D2,1 as downlink carriers in the case of using the selected carrier U1 as an uplink carrier, and the communication are carried out by using only a corresponding carrier in the first downlink bandwidth Wd1 as a downlink carrier in the case of using a carrier other than the selected carrier as an uplink carrier.
