For example, if the number of CSI-RS ports 1 and 2 in Table 4 is "0", the index of the CSI-RS received by the terminal is "0". Then, for DwPTS, the RE position (k', l') of the CSI-RS is (9). 2); For a normal downlink subframe, the RE position (k', l') corresponding to the CSI-RS index of "0" is (9, 5).
- the corresponding resource unit of the CSI-RS in the DwPTS is determined according to the CSI-RS index and the port. For example, the number of CSI-RS ports 1 and 2 in Table 5 is as follows. The index of the CSI-RS received by the terminal is “0”. Then, for the DwPTS, the RE position (k′, l′) of the CSI-RS is (9, 2).
- the number of CSI-RSs can be found to be small when the length of the DwPTS is short, only a part of the CSI-RS configuration index is valid, for example, the number of CSI-RS ports is 1 and 2.
- the effective configuration index is 0, 4, 5, 9, 10, 11, 18, 19.
- the effective CSI-RS configuration index for the 4-port CSI-RS is 0, 4, 5, and 9; the effective CSI-RS configuration index for the 8-port CSI-RS is 0, 4.
- the CSI-RS index that is valid in the DwPTS is less than that of the regular downlink subframe.
- the base station configures the CSI-RS period and the subframe offset.
- the CSI-RS only falls in the regular downlink subframe. In this case, the behavior of the terminal is the same as that of the earlier version.
- the CSI-RS is only in the DwPTS when the base station is configured with the CSI-RS period and the subframe offset. In this case, if the CSI-RS index is invalid (for example, the CSI-RS port number is 1 and 2) 1") Then the terminal thinks that the configuration is wrong.
