Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 11:
12. A method of reducing self-interference due to a dual uplink operation, the method comprising:
performing first communication with a first base station using a first frequency band through a first communication circuit;
performing second communication with a second base station using a second frequency band through a second communication circuit;
determining whether the first communication and the second communication cause interference with each other;
receiving at least one piece of frequency band information from the first base station or the second base station while the processor performs second communication with a second base station using a second frequency band through the second communication circuit;
selecting a third frequency band, based on the at least one piece of frequency band information;
generating a RACH preamble, based on a random access channel (RACH) configuration associated with the third frequency band based on the selected third frequency band; and
transmitting a request by transmitting the RACH to the second base station for the second communication,
wherein the third frequency band different from the second frequency band in at least one of a bandwidth, a center frequency, or a sub-carrier spacing (SCS).
