LTE (3G till Rel 6 - Channel mapping diagram) - 12

Channel mapping diagram [Under LTE > 3G till Rel 6]
» HSDPA overall description - 25.308, Rel 6 «
» FDD Enhanced uplink (HSUPA) overall description - 25.309, Rel 6 «
» Phy channels and their mapping mapping on transport channels - 25.211, Rel 6 «

With the introduction of shared downlink channels (HS-DSCH), both signaling and data bearers can be mapped to HS-DSCH, leaving only (uplink) power control for DPCH. To better the utilisation (of downlink channelisation codes), a shared physical channel, F-DPCH (Fractional Dedicated Physical CHannel) was introduced in Rel 6. F-DPCH is used for both HSDPA and HSUPA.

Find below modified channel mapping diagram (click on image to see enlarged version) for Rel 6 (Rel 5 channel mapping diagram can be found in related UMTS article).
