　　MediaTek and Huawei, China’s largest mobile phone maker, have completed 5G tests in Beijing with the aim of building an industry ecosystem that includes 5G terminals, chipsets, instruments, and networks.

　　MediaTek said that it has completed a prototype terminal that meets the 3GPP 5G standard as well as development and integration of eight mobile-phone-sized antennas. The company said that it and Huawei are the first companies to finish a 5G new radio (NR) interoperability and docking test (IODT) at a transmission rate of more than 5 Gbps.

　　The work in China comes as operators in the U.S. aim at rolling out 5G as early as next year. The new standard is likely to take over a lot of the telecommunications load that is currently handled by fixed-line technology in residential and manufacturing environments.

　　The docking test in China demonstrates the potential of 5G technology in the commercial deployment of sub-6-GHz band communications, said MediaTek in a press statement.

　　“The new 5G terminals will play an important role,” said Kevin Jou, chief technology officer at MediaTek. “We are pleased that MediaTek and Huawei successfully completed the IODT testing. This will be a milestone for 5G terminal innovation, product development, and even for a commercial launch.”

　　MediaTek said that it will promote the development of a global standard for 5G by working with industry partners and governments with the aim of commercializing 5G in the sub-6-GHz band by 2020.

　　The round-trip time for a packet to move between a 5G new radio and the radio access network and back is three milliseconds, down from 20 for LTE. NR will support frequencies from 600 MHz to 100 GHz and channels from 20 to more than 100 MHz, and it can dynamically change the ratio of upstream to downstream traffic that it supports.

　　MediaTek’s 5G terminal prototype and Huawei’s 5G base station completed two key interoperability and docking tests of enhanced mobile broadband (eMBB) and ultra-dense network (UDN) in the 3.5-GHz frequency band and the 200-MHz bandwidth. The test used MediaTek’s 5G prototype terminal with eight phone-sized antennas, demonstrating that transmission efficiency in an indoor environment was equivalent to that in an external environment with a dipole antenna. The 5G prototype terminal can handle high-speed, large-bandwidth, multi-antenna processing, according to MediaTek.

　　The test was organized by China’s IMT-2020 (5G) Promotion Group as part of a second-phase verification of 5G R&D. Technologies such as parameter sets, frame structures, new waveforms, and Polar/LDPC channel coding are defined by 3GPP Rel-15 5G NR and were carried out according to equipment and test specifications developed by the IMT-2020 (5G) promotion group.

MediaTek to Win the 5G Competition by Alliance and Independent R&D

　　The 3GPP standard conference will be held in Taipei, Taiwan, next week. To foster the local 5G supply chain in Taiwan, MediaTek, a key organizer of the conference, strove for keeping the event to be held in Taiwan with the aim of developing universal standards. Huang He-qi, general manager of the design and development department of MediaTek's communication system, pointed out that for the current situation of 5G, MediaTek will adopt the countermeasures of "wide-scale alliance and independent R&D".　　The 3rd Generation Partnership Project (3GPP) is a standard organization dedicating to the development of 5G mobile communication in the world. There are more than 200 international companies participate in and even been called the Olympia Committee of communication standards. Because the standard drafting is like a tug-of-war match, major international companies are hoping to stand in a favorable position to seize the opportunity. Huang He-qi described: "It is a kind of competition, and everybody has their own strategies in it."　　He pointed out that because each company has its technical position, therefore they will push their own technical proposals in the specifications to win its best interests. Huang explained that by pushing the proposal into a standard, in addition to being able to apply for a patent, it is also beneficial for the company to establish a technical threshold, so that competitors have no way to break through, and thus make their products more competitive.　　Facing of this situation, Huang said that MediaTek will take the countermeasure of " wide-scale alliance and independent research" strategy. But he pointed out that the forming alliance is only a short term approach, and more importantly is to build deep technology and with flexible strategies.　　MediaTek emphasizes that the development of 5G technology should not be a solo play, but needs to join hands with industrial partners to create an ecosystem.　　Huang said that the Release 15 version was released in December last year. This year, it will be adjusted for more detail. The Release 16 version is expected to be announced in March 2020. He revealed that MediaTek is also expected to launch related products in 2020 to meet customer needs.

Mediatek Targets China, Snapdragon

Mediatek Targets China, Snapdragon

Mediatek announced its next-generation smartphone SoC just one week after archrival Qualcomm did the same. The Helio P90 falls short of the Snapdragon 855 in many respects but is likely to provide fierce competition a notch below flagship handsets, especially among China’s cost-conscious OEMs.Made in a 12-nm node, the P90 sports two Cortex-75 cores running at up to 2.2 GHz and six A55 cores at 2.0 GHz. By contrast, the 7-nm Snapdragon 855 uses four large cores, one running up to 2.84 GHz and three at 2.42 GHz, and four of the A55 cores at 1.80 GHz.Mediatek switched from a 4 × 4 configuration in its former P70, in which it ran A73 and A53 cores at 2.1 and 2.2 GHz, respectively, apparently not wringing much speed gains out of the 12-nm process. The use of a 2 × 6 configuration signals a strategy focused more on power efficiency.In connectivity, the P90 supports LTE Category 13 with 3× carrier aggregation (CA) up from Cat 7 with 2× CA, claiming downloads at up to 600 Mbits/s. It also supports 802.11ac Wi-Fi with 2 × 2 MIMO.For its part, the Snapdragon 855 integrates a Category 20 LTE modem supporting 7× carrier aggregation and two flavors of Wi-Fi — the 60-GHz 802.11ay and the pre-standard .11ax, both claiming to be capable of 10-Gbit/s data rates. In addition, Qualcomm pitches the 855 with its separate 5G modem, powering first-generation 5G handsets from Samsung and OnePlus early next year in sub-6-GHz and millimeter-wave bands.Mediatek has an M70 standalone 5G modem, but “we’re not certain how widely it will be made available commercially … we’re looking at going directly to an integrated SoC product rather than a standalone modem and focus on sub-6 GHz, aiming for customer products launching in late 2019 or early 2020,” said Russ Mestechkin, senior director of sales and business development at Mediatek.“Our focus is to commercialize our SoC for mainstream handsets at $500+ as opposed to ultra-premium models at $1,000+,” he added.Mediatek won sockets in the 2016 and 2017 models of China’s rising handset makers, but Qualcomm has been regaining ground with them this year. It’s a pitched battle in which Mediatek is “starting to win back share with Xiaomi and Vivo … Oppo and Vivo are also using its P50 in mid- to high-end products, which will bear fruit in 4Q18,” said Phil Solis, who tracks handset SoCs at International Data Corp.When it comes to 5G, “I expect they will gain back some market share by 1H20, but they are far behind” he said. “In the meantime, Mediatek will focus on its growth areas of smart speakers, TVs, IoT devices, and other consumer products for their processors and connectivity.”Both Mediatek and Qualcomm made AI acceleration a focus in multiple blocks of their latest chips.For the P90, Mediatek doubled the size of the so-called APU in the P70, which includes multiply-accumulate arrays for running machine-learning jobs. It also added a proprietary AI accelerator. The two blocks, combined with a PowerVR GM 9446 GPU running at 970 MHz, deliver 1,127 GMACs/s with software optimizations still ahead.The number falls far short of the 7 Tera tensor operations/s on 8-bit integer jobs that Qualcomm claims for its 855. But both sides agree that the benchmarks are less telling than performance on actual AI workloads, which vary widely.The Helio P90 beat the Snapdragon 845 and others on one AI benchmark.

Its NeuroPilot software can dynamically assign AI jobs and supports third-party frameworks, said the company without listing which ones.The P90 can drive dual 24- and 16-MP cameras or one 48-MP camera with video capture at up to 30 fps. It includes dedicated blocks to speed face recognition as well as accelerators for processing 3D depth maps, multi-frame noise reduction, and lens correction.
