PROBLEM TO BE SOLVED: To provide a method for transmitting the muting information, for preventing interference between an adjacent cell and a CSI-RS, to a terminal.SOLUTION: A specific cell receives a CSI-RS pattern, the number of antenna ports, the transfer period, and the offset information from an adjacent cell (S1505), and determines a muting area (S1510). CSI-RS muting information including a first data field representing the period and offset of a muting sub-frame, and a second data field having a bit map of n bits, out of 12-28 bits indicating whether or not the muting is applied by a bit map format, is generated (S1515), and the CSI-RS muting information thus generated is transferred to a terminal (S1520). The data is mapped to a Resource Element by using the CSI-RS muting information, and a signal including the data thus mapped is transmitted to a terminal (S1525). |
