Abstract:
1. A method of processing data in a multi-cell cooperative wireless communication system, the method performed by a user equipment (UE) and comprising: receiving a first control signal for first downlink data and a second control signal for second downlink data; receiving the first downlink data from a serving cell as well as the second downlink data from a neighbor cell, respectively, wherein the first downlink data and the second downlink data interfere with each other, wherein the first downlink data is user data for the UE and the second downlink data is a common portion of user data for another UE but is decodable by the another UE as well as the UE, and wherein the user data for the another UE is divided into the common portion and a private portion which is decodable by the another UE, but not by the UE; decoding the second downlink data received from the neighbor cell; and decoding the first downlink data by removing the interference, which is caused by the first downlink data, from the first downlink data based on the decoded second downlink data.
