FIELD: information technology. ^ SUBSTANCE: disclosed is a base station which communicates with a user device through several antennae in a system, in which a subframe consists of several time intervals, each consisting of several basic unit time intervals. The base station has a first display unit which can display one or more reference signals used to demodulate one or more control channels L1/L2 and one or more data channels transmitted from one or more antennae within a predetermined number of basic unit time intervals, counting from the beginning of each subframe; and a second display unit which can display reference signals used to demodulate data channels transmitted from other antennae, in one or more basic unit time intervals following the basic unit time intervals in which reference signals used to demodulate control channels L1/L2 and data channels are displayed. ^ EFFECT: fewer demodulation templates during reception in a user device. ^ 7 cl, 7 dwg |
