Data transmission and reception method and device using caching in wireless communication system performing compCOMP를 수행하는 무선 통신 시스템에서 캐싱을 활용한 데이터 송수신 방법 및 장치
The present invention relates to a wireless communication system. More specifically, as a method for transmitting data in a wireless communication system performing a CoMP operation by using a cache, a method for transmitting data, according to the present invention, can comprise the steps of: determining a transmission mode among a plurality of transmission modes on the basis of at least one piece of data stored in the cache; determining data to be transmitted in the transmission mode; and transmitting the data according to the determined transmission mode, wherein the transmission mode can comprise: a first mode for coordinately performing data transmission between coordinated base stations; a second mode for coordinately performing scheduling by sharing channel information between the coordinated base stations; and a third mode for combining the first mode and the second mode.
