Continuous Packet Connectivity (CPC)

This topic illustrates some oscilloscope signal examples for the CPC feature.

• E-DCH TTI = 2 msec

• E-DCH TTI = 10 msec

Where E-DCH TTI = 2 msec:

E-DCH TTI = 2 msec

UE_DTX_cycle_1 = 20 subframes

UE_DTX_burst_1 = 2 subframes

Preamble length = 2 slots

Postamble length = 1 slot

Where E-DCH TTI = 10 msec

E-DCH TTI = 10 msec

UE_DTX_cycle_1 = 20 subframes

UE_DTX_burst_1 = 5 subframes

Preamble length = 2 slots

Postamble length = 1 slot
