1. A base station comprising:a receiver that receives a parameter and data from a second base station,
wherein the parameter is used for generating a downlink physical data channel and the data is to be transmitted toward a terminal;
a processor that generates the downlink physical data channel by performing processing of Layer 1 on the data using the parameter; and
a transmitter that transmits the generated downlink physical data channel,
wherein the base station is used as a first base station in a 5G wireless communication system including the first base station, the second base station that communicates with the first base station, and the terminal that communicates with the first base station,
wherein the first base station and the second base station belong to the 5G wireless communication system, and
