 Dual-Cell and MIMO 2x2 each multiply the maximum data rate by 2, because multiple independent transport blocks are transmitted over different carriers or spatial streams, respectively.The data rates given in the table are rounded to one decimal point.Dual-Carrier HSUPA, also known as "Dual-Cell HSUPA", is a wireless broadband standard based on HSPA that is defined in 3GPP UMTS release 9.
