HSPA +

HSPA +, Evolved HSPA (also known as: HSPA Evolution, HSPA +, I-HSPA or Internet HSPA) is defined in 3GPP release 7. Evolved HSPA provides HSPA downlink data transfer rate of 42 Mbit / s upstream and 22 Mbit / s, the use of MIMO technology and more high-speed modulation. HSPA + is HSPA (3GPPR6) down version of evolution is the ability to enhance the bottom line of a technology in the FDD system, uplink and downlink resources are treated separately, so the terminal type to HSPA +, respectively, from top to bottom two perspectives. From the perspective of standard definition, HSPA + downlink traffic channel is a HS-DSCH, so down the terminal type is also known as "HSDPA terminal category," of course, where the "HSDPA terminal category" Unlike 3GPPR5 in HSDPA. Similarly, HSPA + uplink traffic channel is the E-DCH, uplink terminal type so can be called "HSUPA terminal category," also from 3GPPR6 of "HSUPA terminal type."
