9.1 Performance requirement for 3.84 Mcps TDD option
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
The requirements are stated for the HSDPA UE reference combination classes specified in [2] and under the multipath propagation conditions specified in Annex B. The performance metric for HS-DSCH requirements in multi-path propagation conditions is the throughput R measured on HS-DSCH.
9.1.1 HS-DSCH throughput for fixed reference channels
The performance requirements in this subclause apply for the reference measurement channels specified in Annex A.3.2.
During the Fixed Reference Channel tests the behaviour of the Node-B emulator in response to the ACK/NACK signalling field of the HS-SICH is specified in Table 9.1:

ACK |
ACK: new transmission using 1st redundancy version (RV) |
NACK |
NACK: retransmission using the next RV (up to the maximum permitted number or RV’s) |
DTX |
DTX: retransmission using the RV previously transmitted to the same H-ARQ process |
9.1.1.1 Minimum requirement QPSK, Fixed Reference Channel, 7,3 Mbps – Category 8 – UE
For the parameters specified in Table 9.2, the measured throughput R shall exceed the throughput specified in Table 9.3 for each radio condition.

9.1.4 HS-SCCH Detection Performance
The detection performance of the HS-SCCH is determined by the probability of event Em, which is declared when the UE is signaled on HS-SCCH, but DTX is observed in the corresponding HS-SICH ACK/NACK field. The probability of event Em is denoted P(Em).
9.1.4.1 Minimum Requirements for HS-SCCH Detection
For the test parameters in Table 9.7B, for each value of HS-SCCH-1 Ec/Ior specified in Table 9.7C, the measured P(Em) shall be less than or equal to the corresponding specified value of P(Em).
