Japan's NTT DoCoMo has teamed up with the China Academy of Information and Communication Technology (CAICT) on research and development into potential 5G standards.
As part of the collaboration, DoCoMo will join the CAICT-initiated IMT-2020 Promotion Group 5G trial. DoCoMo and CAICT will also evaluate possible frequency bands for future 5G networks.
DoCoMo joined the IMT-2020 promotion group in August to co-operate with major mobile operators and vendors on 5G R&D and standardization.
The operator has also been conducting joint 5G R&D with vendors including Ericsson, Huawei and others.
The IMT-2020 Promotion Group was jointly established by three Chinese ministries in early 2013, based on the original IMT-Advanced Promotion Group. It is the major platform to promote research into 5G in China.
The group is divided into dedicated units covering areas including technology, spectrum, intellectual property and network asrchitectures.
