11 Performance requirement (E-DCH)
25.1023GPPRelease 17TSUser Equipment (UE) radio transmission and reception (TDD)
Unless otherwise stated the receiver characteristics are specified at the antenna connector of the UE. For UE(s) with an integral antenna only, a reference antenna with a gain of 0 dBi is assumed. UE with an integral antenna may be taken into account by converting these power levels into field strength requirements, assuming a 0 dBi gain antenna. For Ues with more than one receiver antenna connector the fading of the signals and the AWGN signals applied to each receiver antenna connector shall be uncorrelated. The levels of the test signal applied to each of the antenna connectors shall be as defined in the respective sections below.
11.1 Detection of E-DCH HARQ ACK Indicator Channel (E-HICH)
The performance of the E-HICH detection is determined by the false ACK probability (probability of detecting an ACK given that a NACK was sent) and the false NACK probability (probability of detecting a NACK given that an ACK was sent).
11.1.1 Minimum requirement
11.1.1.1 3.84 Mcps TDD Option
For the parameters specified in Table 11.1 the average downlink E-HICH Ec/Ior power ratio shall be below the specified value for the false ACK and false NACK probabilities shown in Table 11.2.
