Our researches are focusing on the wireless system technologies to realize the vision of mobile ubiquitous. Universal system control as a new system control technology to enable the systematic integration of ubiquitous network and high speed packet based cellular network is under investigation. Now two projects are performed to achieve the research target.

1.Cross-layer and collaborative control project (3C)

To enhance the performance of existing cellular network and realize a high-capacity, large-coverage, and low-cost network in the future, cross-layer and collaborative control is one of the crucial technologies.

The technical challenges of 3C project are multi-dimensional system resource (time, frequency, space, etc) and novel network architecture, e.g. relay based cellular system and distributed antenna system. To resolve these challenges, 3C project mainly focuses on the key techniques including multi-user MIMO scheduling and resource management, hybrid ARQ, intercell collaboration and system control technologies for novel cellular infrastructure.

2. MAC and interworking project (MAC)

To improve the service continuity, decrease the battery consumption of UE, while taking into account of the multi-system coexistence, MAC and interworking technologies are essential. The technical challenging is the varieties of UE and systems, end-end performance enhancement. This project aims to study access control, power saving control, seamless handover and load-balancing technologies.

To fully exploit the scarce and precious resource of spectrum, innovative technologies are needed to increase the spectrum utilization. Spectrum sharing and Cognitive Radio (CR) are viewed as key enablers to achieve this objective. RSC project aims to study the dynamic spectrum sharing methods between wireless operators and systems, and propose new technologies for increasing spectrum efficiency, enhancing QoS, anti-interference, and network self-organization by using CR.

In order to enhance radio systems, lower bit cost and expand coverage areas economically, advanced system control technologies for future mobile communication systems are essential to achieve this goal. Currently we have three projects. Cross-layer and collaborative control project aims to enhance the performance of existing cellular network and realize a high-capacity, large-coverage, and low-cost network. MAC project aims to improve the service continuity, decrease the battery consumption of UE, while taking into account of the multi-system coexistence. RSC project aims to study new technologies for increasing spectrum efficiency, enhancing QoS, anti-interference, and network self-organization by using cognitive radio.

Targeting the brand-new future mobile communication systems, we are exploring new research area and conduct innovative research topics. Meanwhile, we collaborate with research labs and development divisions in headquarter, jointly promote the research for standardization and commercialization. We are also carrying out joint research with domestic leading universities on B3G field. ?Furthermore, we are inputting our research outcomes to related working groups of FuTURE FORUM. Through these research activities, we are actively promoting the development of future mobile communication of China and the world.

Striving to Become Olympic Player of Research Field

Our researchers come from famous domestic and international research institute and universities. Since the opening of ?DOCOMO Beijing Labs, we have already applied and submitted dozens of patents and papers, we also submitted contributions to standardization meetings, and some of them have been adopted.
We have capable and high potential researchers, have dense and active discussion environment, and have clear vision and output route. If we are enlarging our horizons, setting up higher and more challenging target, striving to become Olympic Players of research field.

At DOCOMO Beijing Labs, a young organization full of vitality, we are challenging new technologies, realizing our dreams and fully putting out our potential capabilities.

Our creativities today will bring a brand-new mobile life tomorrow!
