ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for the Mobile Internet, is showcasing its 5G internet of things (IoT) test bed based on multi-user shared access (MUSA) technology and filter blank-orthogonal frequency division multiplexing (FB-OFDM) technology at Mobile World Congress in Barcelona. ZTE’s products increase the number of connected users by three to six times without extra air interface resources, while providing a solution to 5G IoT data access.

4G focuses on the Mobile Internet while 5G is focused on the mobile IoT. Supporting the access of surplus IoT data when air interface resources are limited is a huge challenge for operators. ZTE accumulates much experience in IoT since 2/3/4G era. Therefore, the access of 5G IoT data will become key to the success or failure of 5G vertical industry applications in the future. MUSA is an innovative multiple access technology based on advanced non-orthogonal multiple access (NOMA) resource sharing. This technology allows multiple terminals to share the same air interface resources and increases the number of connected users by three to six times in IoT scenarios. The technology provides a real solution to data access.

The FB-OFDM waveform technology is one of ZTE's innovative 5G waveform technologies, which dramatically reduces inter-carrier interference through subcarrier-level filtering and helps users flexibly configure air interface resources in accordance with service requirements. Using this method allows spectrum to be put to good use, even the spare spectrum resource is scattered. The technology has laid a solid technical foundation for the establishment of 5G IoT on a large scale in the future.

In addition, ZTE is developing the next-generation 5G IoT prototype based on MUSA, and will fully participate in 5G technology tests and test network establishments in China.
