Join Qualcomm Research at MWC 2015. HSPA Uplink Carrier Aggregation
Improving voice and data performance.
Our HSPA+ Advanced R&D program is focused on improving mobile voice and data performance from the physical layer to the application.
We work on the design, simulations, analysis, standardization, prototyping and technology transfers of new techniques that improve both voice and data services.
HSPA+ Advanced Features
HSPA+ Multiflow delivers multiple, independent data streams simultaneously to address cell edge user experience and uneven network loads.
CPC & Enhanced FACH
Enhancements to improve user experience in a perpetually connected world by increasing smartphone battery life, reducing network signaling, and improving network capacity.
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.
Improve CS voice efficiency so resources can be used to enhance HSDPA capacity. This is achieved without any voice quality loss.
An evolution of Multi Carrier HSPA+ that aggregates unpaired spectrum bands with paired spectrum to offer additional downlink capacity.
Multi Carrier HSPA+
Provide wireless bandwidth aggregation using multiple 5 MHz carriers to provide a higher quality mobile broadband experience.
Uplink Transmit Diversity
The use of multiple transmit antennas at the UE to improve uplink performance, coverage improvements and/ or reduce transmit power.
Uplink Data Compression
Aims to reduce the size of uplink data packets, including TCP/UDP/IP header and data fields.
UMTS900 combines the capabilities of UMTS with coverage benefits of the 900MHz spectrum to provide a low cost solution to improve network coverage and to augment the capacity of existing UMTS networks.
