Embodiment 1
[0133] Figure 5 is a schematic diagram of the mapping pattern 1 of the Normal CP CSI-RS according to the preferred embodiment 1 of the present invention, Figure 5 Specifically, a group of pilot patterns of a PRB Pair of CSI-RS in the CSI-RS subframe in the Normal CP subframe are given. The base station sends the CSI-RS at the position bearing the CSI-RS, and the terminal receives and detects the CSI-RS at the position bearing the CSI-RS.
[0134] The base station maps CSI-RS and / or IMR on at least one of the following OFDM symbol pairs, wherein the OFDM symbol pairs include: OFDM symbol pairs {0, 1}, {3, 4}, {5, 6}, {7, 8}, {9, 10}, {12, 13}.
[0135] The base station maps a set of CSI-RS and / or IMR to the {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} subcarriers of the OFDM symbol pair {0, 1} on one or two or four subcarriers.
[0136] or,
[0137] The base station maps a set of CSI-RS and / or IMR to the {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} subcarriers of the OFDM symbol pai...

The base station sends the CSI-RS at the position bearing the CSI-RS, and the terminal receives and detects the CSI-RS at the position bearing the CSI-RS.
[0162] The base station maps CSI-RS and / or IMR on at least one of the following OFDM symbol pairs, wherein the OFDM symbol pairs include: OFDM symbol pairs {0, 1}, {3, 4}, {5, 6}, {7, 8}, {9, 10}, {12, 13}.
[0163] The base station maps a set of CSI-RS and / or IMR to the {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} subcarriers of the OFDM symbol pair {0, 1} on one or two or four subcarriers.
[0164] or,
[0165] The base station maps a set of CSI-RS and / or IMR to the {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} subcarriers of the OFDM symbo...
Embodiment 3
[0189] Figure 7 is a schematic diagram of the mapping pattern 3 of the Normal CP CSI-RS according to the third preferred embodiment of the present invention, Figure 7 Specifically, a group of pilot patterns of a PRB Pair of CSI-RS in the CSI-RS subframe in the Normal CP subframe are given. The base station sends the CSI-RS at the position bearing the CSI-RS, and the terminal receives and detects the CSI-RS at the position bearing the CSI-RS.
[0190] The base station maps the CSI-RS and / or IMR on the following OFDM symbol pairs, wherein the OFDM symbol pairs include: OFDM symbol pairs {1, 2}, {5, 6}, {9, 10}, {12, 13}.
[0191] The base station maps a set of CSI-RS and / or IMR to the {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} subcarriers of the OFDM symbol pair {1, 2} on one or two or four subcarriers.
[0192] The base station maps a set of CSI-RS and / or IMR to one, two or four subcarriers of the {2, 3, 8, 9} subcarriers of the OFDM symbol pair {5, 6}.
