    Abstract: A method of cancelling interference signals may comprise: receiving, from a transmitting communication node, a first polarization signal including an interference signal and a second polarization signal that is orthogonal to the first polarization signal and includes the interference signal; generating a combined signal by combining the first polarization signal and the second polarization signal using initial combining coefficients; calculating a correlation between the combined signal and one of the first polarization signal and the second polarization signal; selecting final combining coefficients based on the correlation; and generating an output signal by combining the first polarization signal and the second polarization signal using the final combining coefficients.

    Abstract: A timing control method performed by a terminal included in a communication network may include: configuring an initial timing reference based on time information obtained from the communication network; receiving a first downlink (DL) signal from a base station; based on the initial timing reference and the first DL signal, obtaining first transmission time information that is information on a timing when the first DL signal is transmitted by the base station and first reception time information that is information on a timing when the first DL signal is received by the terminal; determining a first timing advance (TA) value based on comparison between the first reception time information and the first transmission time information; and adjusting an uplink (UL) transmission timing for the base station based on the first TA value.
