8.13A Detection of E-DCH Acquisition Indicator (E-AI)
25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)
The receiver characteristics of E-DCH Acquisition Indicator (E-AI) are determined by the probability of correct detection Pde. Pde is defined as a conditional probability of correct detection of E-AI signature given that the E-AI signature is transmitted and AI signature was correctly received.
8.13A.1 Minimum requirement
For the parameters specified in Table 8.45C the 1-Pde shall not exceed the specified value in Table 8.45D. The power settings for downlink channels other than AICH and E-AICH are set as defined in Table C.3 of Annex C.
