In the 5g communication baseband competition, in addition to Huawei, Qualcomm, and MediaTek, domestic violet light zhanrui is also worthy of attention. It has reached the international top level in technology, and is steadily promoting various tests and commercial use.
Today, Ziguang zhanrui announced two new breakthroughs. One is to fully complete the indoor test of 5g SA and NSA based on 3GPP R15 standard. The other is to open the two-way interworking based on the physical link of the uplink and downlink of the 26ghz mmwave. Both belong to the research and development test of 5g enhanced technology in China organized by imt-2020 (5g) promotion group.
According to the introduction, in the 5g SA / NSA indoor test, the test terminal of the Ziguang zhanrui 5g multi-mode chip chunteng 510 was used, and in combination with Huawei and ZTE, the chip and interoperability tests were carried out around the 2.6GHz and 3.5GHz frequency bands, NSA and SA modes.
In MTNet Laboratory of China Academy of information and communication, Ziguang zhanrui has completed all 180 test cases in accordance with 3GPP R15 F40 version, SA and NSA modes.
In SA mode, based on n41 band, the NR downlink peak rate reaches 1.41gbps. In NSA mode, based on B3 + n41 band, the downlink peak rate reaches 1.6gbps.
This test fully verified the technical maturity of ivy 510. At present, the field test is also in progress.
In addition, domestic 5g technology is concentrated in the band below 6GHz, but for millimeter wave band, all basic communication enterprises have not relaxed.
It is reported that Ziguang zhanrui's 26ghz millimeter wave uplink and downlink interworking test uses Ziguang zhanrui's 5g millimeter wave terminal prototype in the key light test instrument.
The prototype mainly consists of baseband, if, RF front-end and phased array. It adopts quasi chip architecture, high-performance hardware platform with multiple reconfigurable capabilities, integrates multi-core processor, high-speed signal processing FPGA array, large-scale antenna array RF module, supports 26ghz / 39ghz frequency band, etc., and can meet the requirements of large bandwidth, high frequency and high-speed rate in 5gnr multi scenarios And multi MIMO verification requirements.
