{0,1}, {3,4}, {5,6}, {7,8}, {9,10} and {12,13}; or, when the terminal detects that a type of a CP of a sub-frame is a normal CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {1,2}, {5,6}, {9,10} and {12,13}; or, when the terminal detects that a type of a CP of a sub-frame is a normal CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {0,1}, {2,3}, {5,6}, {7,8}, {9,10} and {12,13}; or, when the terminal detects that a type of a CP of a sub-frame is a normal CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {1,2}, {4,5}, {7,8}, {9,10} and {12,13}; or, when the terminal detects that a type of a CP of a sub-frame is an extended CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {1,2}, {4,5}, {7,8} and {10,11}; or, when the terminal detects that a type of a CP of a sub-frame is a normal CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {1,3}, {5,6}, {7,8}, {9,10} and {12,13}; or, when the terminal detects that a type of a CP of a sub-frame is a normal CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {1,3}, {5,6}, {8,9} and {12,13}; or, when the terminal detects that a type of a CP of a sub-frame is a normal CP, the receiving component receives the CSI-RS and/or the IMR on one of the following OFDM symbol pairs; {1,3}, {5,6}, {8,9} and {10,12}.
