8.8 Demodulation of DCH in birth-death conditions
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
The receive characteristics of the Dedicated Channel (DCH) in birth-death propagation conditions are determined by the Block Error Ratio (BLER) values. BLER is measured for the each of the individual data rate specified for the DPCH. DCH is mapped into in Dedicated Physical Channel (DPCH).
8.8.1 Minimum requirement
8.8.1.1 3.84 Mcps TDD Option
Void
8.8.1.2 1.28 Mcps TDD Option
For the parameters specified in Table 8.19 the BLER should not exceed the piece-wise linear BLER curve specified in Table 8.20.
