Abstract: Disclosed in the present application is a method for a terminal receiving data in a wireless communication system. Specifically, the method comprises the steps of determining at least one transmission subject for the data among one or more auxiliary nodes and a base station; receiving a distributed code from the determined at least one transmission subject; and obtaining the data from the distributed code, wherein the at least one transmission subject is determined based on the sum of the distributed codes stored in the auxiliary nodes and the number of auxiliary nodes existing within a predetermined distance from the terminal.

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, by a relay node, a content using a cache memory according to the present invention may comprise the steps of: storing a first content, received from a serving cell, in the cache memory; storing a second content, received from an adjacent cell or the serving cell, in the cache memory; selecting a content to be transmitted to a user equipment (UE) from among the first content requested by the UE and the second content which acts as interference to the first content; and transmitting the second content to the UE.

Abstract: Provided is a non-orthogonal multicast transmission for asynchronous data requests. In a multicast transmission method of multicasting data to a plurality of user devices belonging to a base station, the method may include: receiving a request for transmitting a file from user device 1 belonging to the base station; unicasting the requested file to the user device 1; receiving a request for transmitting the file unicast to the user device 1 from user device 2 belonging to the base station; and switching to multicast and multicasting the file after unicasting the file to the user device 1 and the user device 2 for a certain time.

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.
