Title:
METHOD AND DEVICE FOR SELF-INTERFERENCE CANCELLATION IN FULL-DUPLEX COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/007172
Kind Code:
A1
Abstract:
Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A method for cancelling self-interference in a full-duplex communication system is provided. The method comprises the steps of: cancelling cancellable self-interference components through an analog interference cancellation circuit, and estimating a channel state of an uplink channel and a channel state of a downlink channel on the basis of remaining residual self-interference components; estimating a channel capacity for each of all possible beam combinations on the basis of the estimated uplink channel state and downlink channel state; selecting the beam combination having the largest channel capacity from among all the possible beam combinations; and cancelling self-interference from a received signal on the basis of the selected beam combination.
