The requirement in the table assumes time to trigger of 0 ms as well no L3 filtering of the physical layer measurement results. An E-UTRA cell is considered 'detectable' if the SCH and RS subcarrier power is above -125 -122 dBm (depending on the frequency band) and the subcarrier to noise and interfer- ence power ratio for RS and SCH is above -6 dB. For UTRA FDD, in turn, the requirement is that UE must be able to detect a cell with CPICH Ec/NO above -20 dB and SCH Ec/NO above - -17 dB. In 3GPP Release 9 require
