Abstract:
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting a content using a cache memory, and a method for transmitting a content using a cache memory by a relay node according to the present invention may comprise the steps of: storing a first packet among a plurality of the packets constituting the content in the cache memory; decoding a second packet among the plurality of packets constituting the content; and when the second packet has been successfully decoded, combining the first packet and the second packet and transmitting the combined packet to a terminal, wherein the second packet is not already stored in the cache memory.
