MediaTek 5G preemptive: release the world's first 5G SoC chip

MediaTek's 5G chip not only has advantages in terminal low-power technology, uplink enhancement technology and highest peak rate, but also the world's first manufacturer to release 5G SoC chips.

For the NSA and SA networking methods that have been debated for a long time, due toChina MobileChairman Yang Jie clearly stated that "5G will begin on January 1 next year.Mobile phoneMust have SA mode, NSA mobile phones can not enter the network. "Causes the industry not to shake.

Because exceptHuaweiIn addition, the Qualcomm X50 baseband chips used by other mobile phone manufacturers only support the NSA mode. China Mobile's unexpected move made chip makers somewhat unprepared, and Qualcomm also stepped up the next generation X55 release rhythm to support NSA/SA.

At this time, MediaTek has "accidentally pressed the direction." Fu Yikang revealed that when Lianfa Technology plans the underlying capabilities of the 5G chip in the early stage, it hopes to achieve global versatility, so it considers supporting the NSA/SA networking mode. It is understood that in the early days of 4G development, MediaTek launched research on 5G.

In the 5G chip design, MediaTek developed the coverage and rate enhancement technology for the upstream of NSA and SA. The uplink coverage enhancement technology of the MediaTek NSA mode can bring an average uplink rate increase of 28%; and the uplink coverage enhancement technology of the MediaTek SA mode brings 30%-60% coverage improvement to the UL uplink control channel precoding technology. The 40% UL high-power terminal brings 40% uplink coverage boost, which is equivalent to an equivalent 25% uplink rate increase.

In addition to 5G uplink enhancement technology, it has always been the strength of MediaTek in low power consumption. 5G terminal power consumption is higher than 4G due to greater bandwidth, higher speed and lower latency. In the case that the terminal battery capacity is still limited, how to make the terminal low power consumption is related to the user experience.

MediaTek has developed a BWP solution based on the technical concept of “avoiding unnecessary power consumption when data transmission is avoided”, which is a bandwidth-saving power-saving scheme. By dynamically adjusting the terminal bandwidth, the transmission performance is maximized while maintaining the transmission performance. The effect of electricity makes the battery of the terminal really make the best use of it.

It is understood that this BWP solution of MediaTek has been written into the 3GPP Rel-15 standard.

In terms of speed, the Helio M70 has the industry's highest Sub-6GHz band transmission specification of 4.7Gbps, which is the fastest measured speed in the industry. The Huawei Balong 5000 achieves 4.6Gbps in the Sub-6GHz band. The Qualcomm X50 is 2.3Gbps in the Sub-6GHz band. .

In terms of the maturity of 5G chip technology, the "IMT-2020 (5G) Summit in 2019" announced the current 5G chip test situation: HiSilicon and MediaTek supported the SA/NSA network model, and Hess completed indoor and outdoor testing. MediaTek completed the indoor test; Qualcomm completed the NSA test.

Therefore, MediaTek's 5G chip is not only the leader in low-power technology and uplink enhancement technology, but also the fastest in 5G peak rate.

"It can be said that MediaTek's 5G chip technology does not lose the strongest chip that everyone thinks." Fu Yikang said.

Compared with the slightest out of 4G, MediaTek has taken the lead in 5G and is in the lead of 5G. According to reports, OV has begun to consider MediaTek andSamsung5G baseband chip.

Previously, it was reported that MediaTek's latest 5G SOC single-chip adopts the 7-nanometer process. This year, Q3 will deliver samples to major customers. The first batch of terminals equipped with 5G SOC will be available in the first quarter of 2020.
