Chinese equipment vendor ZTE Corporation has revealed a new Multi-User Shared Access (MUSA) technology, which it claims is capable of more than tripling the overload capacity of wireless access networks. Based on simulation results, ZTE’s MUSA algorithm delivered an improvement of over 200% in the overload radio, thus ‘helping to transition networks for the era of the Internet of Things (IoT)’. MUSA is one of ZTE’s ‘Pre5G’ research projects, which use 5G-ready technologies to provide commercial Long Term Evolution (LTE) end-users with next generation access experience. Further, ZTE successfully tested its Pre5G Ultra-Dense Network (UDN) solution, which utilises Pico Remote Radio Unit (RRU) hardware platform and Cloud Radio interference cancellation technology, allowing for denser deployment of base stations in order for operators to gain higher capacity density. ZTE expects that its Pre5G technologies – MUSA, Massive multiple input, multiple output (MIMO) and UDN – will be commercially deployed in 2015.
Xiang Jiying, chief scientist at ZTE, said: ‘The validation of MUSA and UDN technologies further enhances the Pre5G solutions … It will help operators exponentially enhance the access rate and overall network capacity by leveraging existing resources in the next three-to-five years. Before standardisation of 5G technologies, this solution can effectively mitigate the challenges of data traffic surge, and help operators seize market opportunities and achieve better business development.’
As previously reported by CommsUpdate, in January 2015 ZTE completed a ‘world first’ pre-commercial field test of multi-user and multi-stream transmission on a Massive MIMO base station, which demonstrated peak data throughput more than three times that of traditional base stations and average data throughput that exceeded conventional systems by at least five times.
