8.3A Demodulation of DCH in high speed train condition
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
8.3A.1 General
The performance requirement of DCH in high speed train conditions is determined by the maximum Block Error Ratio (BLER). The BLER is specified for each individual data rate of the DCH. DCH is mapped into the Dedicated Physical Channel (DPCH).
8.3A.2 Minimum requirement
8.3A.2.1 3.84 Mcps TDD Option
<void>
8.3A.2.2 1.28 Mcps TDD Option
For the parameters specified in Table 8.9C, the average downlink power ratio shall be below the specified BLER shown in Table 8.9D.
