Abstract: In this disclosure, methods for pre-compensation of the phase shifting error, and apparatuses for the same are disclosed. In one example, a device performs precoding of a digital signal, while acquiring information on an error caused by a phase shifting of the precoding. Then, the device performs phase compensation on the digital signal based on the acquired information. Here, the phase compensation may compensate different amount of phase based on an amount of the phase shifting of the precoding. This phase compensated-digital signal is converted to an analogue signal, and is transmitted to a receiver.

Abstract: In this disclosure, methods and apparatus for managing interference are disclosed. In one example, the first station receives the first signal from the base station. The first station acquires information on a specific processing scheme of a second station for processing the first signal to be transmitted to a third station at the second station. The first station receives a second signal from the base station while the second station transmits the first signal to the third station. Here, since the first station has knowledge on the first signal and the information on the specific processing scheme, it can manage interference caused by the first signal from the second station.
