Huawei and Qualcomm Technologies demonstrated its Multi-Carrier and Multi-Flow (MCMF) solution over four High Speed Downlink Packet Access (HSDPA) data streams.
This was announced at the Mobile World Congress MWC 2014, Barcelona.
Huawei in a statement said that the solution provides the same or higher data rates when a connected mobile device is on the edge of the cell compared to when it is at the center to ensure a uniform No-Edge user experience.
The MCMF solution mitigates mobile broadband challenges by aggregating, at the mobile terminal, up to four HSDPA data streams coming from one or two sites. For the end user, the MCMF solution provides an improved user experience at the cell edge. For operators, the MCMF solution can balance traffic loads for adjacent cells to improve overall system throughput.
In January 2014, Huawei and Qualcomm achieved up to 60 Mbps of downlink user throughput by using four HSDPA carriers in 10MHz spectrum bandwidth. The test also showed that the MCMF solution can provide 2 times user throughput compared with Dual-carrier HSDPA (DC-HSDPA) data rate.
Wang Yixiang, president of Huawei’s UMTS product line, said: “Our goal is to maximize the end user experience of the UMTS network.”
Mario Scipione, senior vice president, Technology, Qualcomm Technologies, said: “As part of Qualcomm Technologies’ initiative to solve the 1,000 times data challenge to address the wireless industry’s unprecedented data demand, the MCMF solution was designed to help operators maximize the cell edge user throughput and utilize spare capacity from neighboring cells.”
The MCMF solution is based on a 3GPP Rel-11 multi-flow feature which was standardized by 3GPP in 2012. Huawei is working to further develop and release a commercial version of the MCMF solution.
