 Its evolution LTE Advanced supports maximum downlink rates of over 1 Gbit/s.Enhanced Uplink adds a new transport channel to WCDMA, called the Enhanced Dedicated Channel (E-DCH).It also features several improvements similar to those of HSDPA, including multi-code transmission, shorter transmission time interval enabling faster link adaptation, fast scheduling, and fast Hybrid Automatic Repeat Request (HARQ) with incremental redundancy making retransmissions more effective.
