Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

The four transmit antennas 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.

9.2.4B.1 Requirement Fixed Reference Channel (FRC) H-Set 13A/13C

The requirements are specified in terms of a minimum information bit throughput R for the DL reference channels H-Set 13A/13C specified in Annex A.7.1.13, with the addition of the parameters in Table 9.22I1 and the downlink physical channel setup according to Table C.12F.

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

Using this configuration the throughput shall meet or exceed the minimum requirements specified in Table 9.22I2 with the downlink physical channel setup in Table C.12F.

* Notes: 1) For Fixed Reference Channel (FRC) H-Set 13A the reference values for R should be scaled (multiplied by 2). 2) For Fixed Reference Channel (FRC) H-Set 13C the reference values for R should be scaled (multiplied by 4).

9.2.4B.2 Requirement Fixed Reference Channel (FRC) H-Set 14A/14C

The requirements are specified in terms of a minimum information bit throughput R for the DL reference channels H-Set 14A/14C specified in Annex A.7.1.14, with the addition of the parameters in Table 9.22J1 and the downlink physical channel setup according to Table C.12F.

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

Using this configuration the throughput shall meet or exceed the minimum requirements specified in Table 9.22J2 with the downlink physical channel setup in Table C.12F.
