HSPA+ Advanced

Qualcomm’s HSPA+ Advanced R&D program is focused on improving mobile voice and data performance from physical to application layers.
We propose and demonstrate new techniques that improve both voice and data services, involving design, simulations, analysis, standardization, prototyping and technology transfers.
WCDMA+: Voice & Data Capacity Enhancements
Improves CS voice efficiency so saved resources can be used to enhance HSDPA capacity. This is achieved without any voice quality loss by means of Physical layer and the EVS voice codec enhancements.
HSPA+ HetNets
Provide significant network capacity improvements by increasing offloading to small cells with Dual Carrier Range expansion, Multiflow DFDC and Load Based Serving Cell Selection Techniques.
HSPA+ Multiflow
HSPA+ Multiflow (formerly Multipoint Transmission) delivers multiple simultaneous data streams to address cell edge user experience and uneven network loads.
Supplemental DL
An evolution of Multi Carrier HSPA+ that aggregates unpaired spectrum bands with paired spectrum to offer additional downlink capacity.
Uplink Transmit Diversity
The use of multiple transmit antennas at the UE to improve UL performance, coverage improvements and/ or reduce transmit power.
Multi Carrier HSPA+
Provide wireless bandwidth aggregation using multiple 5 MHz carriers to provide a higher quality mobile broadband experience.
Scalable UMTS (S-UMTS)
The goal of Scalable UMTS (S-UMTS) is to enable UMTS support in a fraction of full UMTS carrier bandwidth without significant impact to spectral efficiency, link budget, device complexity and system design.
