IT Home December 21 news, according to the China Academy of Information and Communications Technology IMT-2020 (5G) promotion group news, recently, ZTE for the first to complete the 5G millimeter wave base station full function and field performance test project, but also the first successful completion of the system and third-party terminal docking test.
The field measured the high and low frequency dual connection (NR-DC) user downstream peak rate of more than 8.3Gbps, and the multi-user sub-cell downlink peak rate exceeded 14.3Gbps.
IT Home learned that in this test, ZTE based on the high-performance low-power millimeter wave NR base station and Qualcomm Snapdragon X65 5G modem and RF system, using millimeter wave and 3.5GHz (n78) band 100 MHz bandwidth NR-DC networking, completed the millimeter wave single carrier 200MHz, DDDSU and DSUUU different frame structures, downstream 256QAM, millimeter wave downstream four 200MHz and upstream two 200M Carrier aggregation and other functions and all field performance tests.
In the field throughput performance test, mmWave adopts a DDDSU frame structure, and the NR-DC single-user downlink peak rate is greater than 8.3Gbps, and the multi-user cell downlink peak rate is greater than 14.3Gbps.
In September this year, ZTE and its partners completed the first 5G high-low frequency dual connection (NR-DC) laboratory test in China, and completed all functional test entries of NR-DC in the laboratory of the Academy of Information and Communications Technology for the first time; in October, it completed the industry's first NR-DC field test with a peak rate of 2.2 Gbps for uplink single users in DSUU, with an uplink peak rate of more than 8.3 Gbps in multi-user cells.
