Regulatory requirements and characterisation of transmitter and receiver parameters to set a novel framework for spectrum sharing

Increase in demand for spectrum due to new radio technologies such as 5G creates challenges for regulatory bodies to enable spectrum sharing. Regulatory limits for new types of equipment need to be set to enable sharing between different systems in the same or adjacent frequency bands. A balanced approach between limits for transmitter and receiver parameters is necessary in this context. Such limits are typically derived from coexistence studies which need to be based on realistic assumptions of device performance to ensure overall efficient and interference-free use of spectrum. This paper discusses recent developments in European regulations within the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) to enable new approaches for spectrum sharing in this context.
