  • An advantage of this approach is that the DPCCH power is raised only when required for HS-DPCCH signalling. This reduces the power consumed at the UE, and also removes the boosted DPCCH channel, which acts only as a noise source if no HS-DPCCH transmission accompanies it.

These increments are activated upon detection in the UE and/or Node B, as appropriate, that the HS-DPCCH channel is about to become active. The increments may be removed when the HS-DPCCH ceases to be active.
