NTT DOCOMO is working with MediaTek of Taiwan to jointly develop and conduct trials of technology that will enable increased data capacity for 5G systems.
The trials, which will be conducted in either Taiwan or Japan from 2017 onwards, will develop a communication system to combine non-orthogonal multiple access (NOMA) wireless access technologies from DOCOMO and multi-user interference cancellation (MUIC) technologies from MediaTek. NOMA multiplexes signals at a base-station transmitter to leverage the increased signal processing capacity of a user device to cancel interference among multiplexed user signals. MUIC utilizes receiver antennas to remove interference from other users and increase capacity when a base station transmits a signal to a number of users at the same time.
The two companies will also study a new 5G Radio Access Technology and chipsets required for 5G devices, with joint trials to be carried out from 2018 onwards.
"DOCOMO is excited to work with MediaTek, an innovator with expertise in the technical requirements of 5G," said Seizo Onoe, Executive Vice President and Chief Technology Officer at DOCOMO. "The potential opportunities for 5G to enable people to connect with devices are endless. We're eager to see our 5G network inspire innovative inventions to benefit technology, life and business."
