Rapporteur:  Mr. Ahmed, Ayaz

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.
