TD-HSDPA Key Technologies

TD-HSDPA is featured by:
High requirements on transfer delay and reliability;
Lots of data bursts and the seeking of large system data throughput;
Packet access technology:
Adapt to changes in channel conditions by adjusting data transfer rate;
In order to meet the above objectives, the following key techniques are adopted to realize higher data transfer rate;
Adaptive Modulation and Coding (AMC)
Hybrid Automatic Repeat Request (HARQ)
Fast Scheduling
Newly Added Channel (including downlink HS-PDSCH, downlink HS-SCCH and uplink HS-SICH)
