On January 8, the reporter was informed that Qualcomm, Ericsson, and AT&T had previously announced plans to cooperate in interoperability testing and OTA field testing based on the 5G NR specification.
It is reported that the interoperability testing and testing program will be launched in the United States in the second half of 2017, with the aim of closely tracking and helping to accelerate the global 5G standard using the bands below 6 GHz and the millimeter wave band. Currently 3GPP is developing the 5G NR specification, which will become the basis of global standards. The first version of the official 5G NR specification will be released as part of Release 15. The trial was designed to help the mobile ecosystem enable faster 5G deployments based on 5G NR-compliant infrastructure and endpoints after 3GPP completed the first version of the official 5G NR specification.
The test will support millimeter-wave spectrum operation and is designed to accelerate commercial deployments in the 28 GHz and 39 GHz bands. In the trial, the three companies will showcase a number of new 5G NR millimeter wave technologies that use the large bandwidth available in the HF band to increase network capacity and achieve multi-gigabit data rates per second. These technologies are critical to meeting the growing demand for consumer connectivity, which will support emerging consumer mobile broadband experiences such as virtual reality, augmented reality and networked cloud services.
The trial will use terminal and base station prototyping solutions from Qualcomm Technologies and Ericsson, respectively, and AT&T will provide spectrum to simulate real-world usage scenarios and cover a wide range of use cases and deployment scenarios. The trial will use 3GPP 5G NR Multiple Input Multiple Output (MIMO) antenna technology and adaptive beamforming and beam tracking to deliver robust and continuous mobile broadband communications in higher frequency bands, including non-line of sight (NLOS) environments and terminal mobility. .
In addition, the trial will use OFDM-based scalable waveform technology and a new flexible frame design, which are expected to be part of the 5G NR specification.
