High Speed Downlink Packet Access is based on techniques such as adaptive modulation and hybrid ARQ to achieve high throughput, reduce delay and achieve high peak rates. It relies on a new type of transport channel, the HS-DSCH, which is terminated in the Node B. HS-DSCH is applicable only to PS domain RABs. In FDD, the HS-DSCH reception is also supported in CELL_FACH, CELL_PCH and URA_PCH state.

This TS is related to the overall support of High Speed Downlink Packet Access in UTRA.
