High Speed Uplink Packet Access (HSUPA) is an enhancement of the UMTS radio-interface to make higher data rates possible in the uplink. To do so, HSUPA introduces an enhanced dedicated channel (E-DCH). In UMTS Release 6, HSUPA is referred to as E-DCH.
HSUPA improves the coverage, the througput as well as the delay of the uplink dedicated transport channels.
HSUPA is the counterpart of HSDPA, which improves the data rate on the downlink.
