9.2.4 MIMO Performance

25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)

The MIMO performance of the High Speed Physical Downlink Shared Channel (HS-DSCH) in multi-path fading environments is determined by the information bit throughput R.

9.2.4.1 Requirement Fixed Reference Channel (FRC) H-Set 9/9A/9B/9C/9E

The requirements are specified in terms of a minimum information bit throughput R for the DL reference channels H-Set 9/9A/9B/9C/9E specified in Annex A.7.1.9, with the addition of the parameters in Table 9.22E1 and the downlink physical channel setup according to Table C.9 and Table C.12D. Precoding weight set restriction shall not be enabled.

The primary precoding vector signalled on the HS-SCCH and applied on the associated HS-DSCH subframe shall correspond to the preferred primary precoding vector reported immediately before the start of the HS-SCCH subframe.

The determination of applied precoding vector for single transport block transmission shall be as follows: the reported preferred primary precoding vector shall be applied to the primary transport block.

The determination of applied precoding vector for two transport block transmission shall be as follows: If the CQI reported by the UE indicates a preference for a single transport block, the preferred primary precoding vector shall be applied to the primary transport block. If the CQI reported by the UE indicates a preference for two transport blocks, and the preferred primary precoding vector corresponds to the highest reported CQI value, the preferred primary precoding vector shall be applied to the primary transport block. If the CQI reported by the UE indicates a preference for two transport blocks, and the preferred primary precoding vector does not correspond to the highest reported CQI value, the preferred primary precoding vector shall be applied to the secondary transport block.

Using this configuration the throughput shall meet or exceed the minimum requirements specified in Table 9.22E2 with the downlink physical channel setup in Table C.9, and the minimum requirements specified in Table 9.22E3 with the downlink physical channel setup in Table C.12D.
