8.3.1 Multipath fading Case 1
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
The performance requirement of DCH 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).
8.3.1.1 Minimum requirement
8.3.1.1.1 3.84 Mcps TDD Option
For the parameters specified in Table 8.4 the BLER should not exceed the piece-wise linear BLER curve specified in Table 8.5. These requirement are applicable for TFCS size 16.
