High Speed Physical Downlink Shared Channel is the physical layer implementation that maps the transport data from the HS-DSCH for transmission over the air interface. A base station can allocate multiple physical channels to a single user equipment simultaneously to boost peak data rates. It utilizes a fixed spreading factor of 16 to maintain high bandwidth efficiency.

If the terminal can't decode the HS-PDSCH, check the signal-to-noise ratio at the cell edge.
