PROBLEM TO BE SOLVED: To efficiently notify a terminal of information for demodulating a signal addressed to another terminal from a downlink signal.SOLUTION: A base station 1 generates a downlink signal including, as extraction information, first terminal reference information to be used for estimating a power distribution of a signal addressed to a first terminal in the downlink signal and another terminal reference information to be used for estimating a power distribution of a signal addressed to another terminal in the downlink signal; generates a control signal including arrangement information showing positions of resource elements, in the downlink signal, to which the first terminal reference information and another terminal reference information are individually allocated; and transmits the generated downlink signal and control signal to the first terminal 2A and the other terminal.SELECTED DRAWING: Figure 1 |
