12.2 Demodulation of DCH in static propagation conditions

25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)

The performance requirement of DCH in static propagation 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).

12.2.1 Minimum requirement

12.2.1.1 3.84 Mcps TDD Option

[FFS]

12.2.1.2 1.28 Mcps TDD Option

For the parameters specified in Table 12.2 and Table 12.3 the BLER should not exceed the piece-wise linear BLER curve specified in Table 12.4.
