Abstract:
A method of frequency utilization in mobile communication having an uplink communication frequency bandwidth Wu which contains n pieces of carriers within a frequency bandwidth W, a first downlink communication frequency bandwidth Wd1 which contains n pieces of carriers within a frequency bandwidth W similarly, and a second downlink communication frequency bandwidth Wd2 which contains m pieces (mselecting m pieces of carriers among the n pieces of uplink communication carriers as selected carriers; setting the n pieces of uplink communication carriers of the uplink communication frequency bandwidth Wu and the n pieces of downlink communication carriers of the first downlink communication frequency bandwidth Wd1 respectively in one-to-one correspondence; setting said m pieces of the selected carriers and the m pieces of downlink communication carriers of the second downlink communication frequency bandwidth Wd2 respectively in one-to-one correspondence; carrying out communications using a corresponding carrier in the first downlink communication frequency bandwidth Wd1 and a corresponding carrier in the second downlink communication frequency bandwidth Wd2 as downlink communication carriers in a case of using said selected carrier as an uplink communication carrier; and carrying out communications using only a corresponding carrier in the first downlink communication frequency bandwidth as a downlink communication carrier in a case of using a carrier other than said selected carrier as an uplink communication carrier.
