Abstract: An operation method of a first communication node in a communication system may include: determining whether each of one or more interference signals satisfies an LOS condition or an NLOS condition, the one or more interference signals being received through a first antenna composed of a plurality of antenna elements; estimating incident direction(s) of the one or more interference signals; performing spatial filtering based on the incident direction(s) of the one or more interference signals, with respect to each of a plurality of array antenna combinations each of which is determined at least in part based on some of the plurality of antenna elements; and receiving wireless signals based on a result of the spatial filtering.

Abstract: An adaptive multi-view streaming processing method and apparatus for a multi-view stream is disclosed. Specifically, disclosed herein is a method and apparatus for adaptively processing or transmitting adaptive streaming by reflecting network states and changes in transmission environments in a multi-view streaming service environment where several or more multiple videos are simultaneously transmitted at an arbitrary moment. An adaptive streaming processing method for a multi-view stream may comprise selecting and downloading an i-th segment of a main view stream with a first quality level, inferring a size of an i-th segment of downloadable neighboring view streams based on a download time and transfer rate of the i-th segment of the main view stream, and selecting a second quality level corresponding to the inferred size of the i-th segment of the neighboring view streams and downloading the i-th segment of the neighboring view streams based on the selected second quality level.
