9th October 2015, 5G Innovation Centre, University of Surrey


Dr Tian Hong LOH, Dr David Humphreys and Dr Tim Brown (5G Innovation Centre (5GIC), University of Surrey) have jointly organised and attended a MET5G (Metrology for 5G Communications) Workshop on ‘the Requirements of Interference Characterisation in 5G Communication Systems’, hosted in the 5GIC, University of Surrey on 9th Oct. 2015. The signal-to-interference-plus-noise ratio (SINR) is a quantity which is widely used in theoretical studies of channel capacity in wireless communications. Interference is deemed to be any unwanted signal that is picked-up from other communications system, or between components within a system. Existing definitions of SINR are available but as the SINR is currently not defined by 3GPP in today’s wireless systems (such as LTE and LTE-A) and as 5G is an entirely different implementation with many additional degrees of freedom, a wide range of definitions will be needed.


Such implementations include massive MIMO, mm-Wave communications and multiple communication devices within close proximity. This workshop provided consultation with industry and members of standards bodies to identify clear requirements for a definition of SINR as well as traceable methods to characterise such metrics. A presentation with an overview of the EURAMET Metrology for 5G Communications (Met5G) project was delivered from which a facilitated discussion took place to achieve this aim. The outcomes from the workshop will provide valuable guidance on the direction of the Met5G project (more information about the project is available at www.met5g.eu). Attendees were from across both the key UK and EU Wireless Communication Industries and Universities such as Samsung (UK), BBC (UK), Thales (France), Rohde-Schwarz (Germany), Bluetest (Sweden), Huawei (UK), EE (Everything Everywhere, UK), Fujitsu (UK), Telefonica (UK), Anite (UK), Roke Manor (UK), University of Bristol (UK), Queen Mary University of London (UK), University of Surrey (UK), etc. Many useful new industrial and academic inputs were noted, which would help us to identify requirements for a definition of SINR as well as traceable methods to characterise such metrics for MET5G project.
