Method for FDR scheme-using communication device transmitting reference signals for estimating channel of non-linear self-interference signal
First Claim
1. A method for transmitting a reference signal for channel estimation of a non-linear self-interference signal by a communication device using a full duplex radio (FDR) scheme, the method comprising:
- transmitting reference signals for channel estimation of the non-linear self-interference signal on a specific symbol of a corresponding subframe,wherein a sequence mapped to the reference signals is subjected to discrete Fourier transform (DFT) and generated in a frequency domain, andwherein the generated sequence is mapped to a resource element (RE) for the reference signals in the frequency domain.

Abstract
A method for a FDR scheme-using communication device transmitting reference signals for estimating a channel of a non-linear self-interference signal comprises the step of transmitting, on a specific symbol of a corresponding subframe, reference signals for estimating the channel of the non-linear self-interference signal, wherein a sequence mapped to the reference signals is a sequence generated in a frequency domain by being discrete Fourier transform (DFT)-converted, and the generated sequence may be mapped, on the frequency domain, to a RE for the reference signals.
