At present, 5G has become a hot topic in the industry. In particular, the completion of the first phase of the 5G technology R&D test in China's IMT-2020 (5G) promotion group has been widely discussed in the industry. The two iconic changes from 4G to 5G are: faster data rates and new applications. In the view of Dr. Fan Mingxi, vice president of engineering and technology at Qualcomm, 5G will be a unified connection platform for future innovation. Fan Mingxi pointed out that 5G can support secure cloud access at any time, support enhanced mobile broadband, support low-latency, critical service-type services with high security and reliability requirements, and support massive Internet of Things. One of the keys to 5G's ability is the increase in data transmission rate. At the same time, 5G network latency is further reduced, which is critical for supporting mission-critical control with high security requirements. 5G is a unified connectivity platform for future innovation. This requires the design of 5GNR (new air interface), which is a more unified unified air interface based on OFDM, which can support diversified deployment, diversified spectrum and diverse services and terminals. In terms of spectrum type, Fan Mingxi said that 5GNR will support all spectrum types such as licensed band, shared band, and unlicensed band. It is worth mentioning that shared spectrum will support a new shared spectrum mode, which will bring high gain. The 5GNR shared spectrum accommodates flexible wireless deployments, flexible, unlicensed operations, and flexible spectrum sharing. Qualcomm has done a lot of research on spectrum sharing. In terms of flexible wireless deployment, the spectrum can support the frequency band from below 6 GHz to the millimeter wave band; in flexible non-authorized operation, it can support multiple connections such as LTE and Wi-Fi, and support unlicensed spectrum; in flexible spectrum sharing, Supports dynamic sharing of different deployment scenarios, technologies, and priorities, supports enhanced millimeter-wave spatial separation, and a new shared spectrum mode solution. In specific frequency band applications, Fan Mingxi believes that high frequency bands above 24 GHz (millimeter wave) will support extreme bandwidth applications; 1 GHz to 6 GHz IF bands for enhanced mobile broadband and mission-critical larger bandwidth; below 1 GHz for low-frequency bands Broader reach and greater reach of massive IoT. In the field of millimeter wave technology, Qualcomm has become a leader and is driving technological innovation to achieve millimeter wave mobilization. In the 28GHz band, Qualcomm is actively developing 28GHz millimeter-wave RFICs. In the 60 GHz space, Qualcomm has launched an 802.11ad60GHz RF front-end chip for mobile terminals. Fan Mingxi revealed that Qualcomm will jointly test and early deployment of the millimeter wave field in late 2017 or early 2018. In addition to its outstanding performance in the 28 GHz and 60 GHz fields, Qualcomm has also introduced the 5GNR prototype system and test platform below 6 GHz, taking performance to a whole new level. The platform operates in the 6 GHz band, enabling flexible deployment, support for comprehensive network coverage and wide use cases; enabling multi-gigabits per second and low latency; can be used to drive 5GNR standardization; will be used as a test platform for influential 5GNR test. The successful commercialization of 5G depends on the maturity of technology and standard specifications, and on the other hand, the maturity of the terminal chip process. In 2012, the chip needs to support various technologies such as TD-LTE, LTE FDD, CDMA, and TD-SCDMA. Nowadays, the chip becomes more complicated, in addition to basic 2G, 3G, Wi-Fi, and LTE technologies, it also needs support. Different frequency bands also need to support multiple carrier aggregation. "To meet the current needs, we need to integrate all the requirements on the same chip. So far, Qualcomm modem features have more than 2,000, and continue to increase." Fan Mingxi pointed out. In the 5G era, more bands with different bandwidths will be added, and more advanced antennas and IoT technologies will also be added to the chip, and the complexity will further increase. "On the one hand, we actively promote the development of 5G industrialization through technology verification. On the other hand, we are also actively researching and developing terminal chip products, so that various technologies, frequency bands and different applications can be collected in the same chip, providing the most users for the future. Good experience." Fan Mingxi said. Speaking of 5G commercial time, Fan Mingxi believes that 5GNR standardization will end in 2018, and it is expected that 5G can be commercialized in 2019 or around 2020. At the same time of 5G evolution, LTE technology will continue to evolve.
