Dual-Cell HSUPA (also known as: Dual-Carrier HSPA or Dual-Cell HSPA) is a wireless broadband standard based on HSPA that is defined in 3GPP UMTS release 9.
Dual Cell (DC-)HSUPA is the natural evolution of HSPA by means of carrier aggregation in the uplink. Downlink carrier aggregation named Dual-Cell HSDPA was already standardized in UMTS Release 8. UMTS licenses are often issued as 10 or 15 MHz paired spectrum allocations. The basic idea of the multicarrier feature is to achieve better resource utilization and spectrum efficiency by means of joint resource allocation and load balancing across the uplink carriers.
The specification is to be completed by December 2009 and details of this technology are in the process of standardisation right now.
- Deployments
The specification will be completed in December 2009 and first deployments can be expected early 2011 after development and first tests and trials in 2010.
