Derivation of Emission Limits up to 40 GHz in the Era of 5G New Radio Services

A probabilistic model and method for deriving radiation limits are presented considering fifth generation (5G) systems. The emission criteria are defined relative to the receiver’s system noise level independently of modulation and coding schemes of 5G, which makes limits derivation much simpler. The interference scenario is characterized by the two-dimensional density of interference sources and the minimum separation distance from the receiver. Typical probabilistic factors, radiation directivity, receiver antenna gain, time/frequency coincidences, and building effects are applied. Limit values are derived with an 80% probability that the interference level from the most contributing source will be lower than the protection criteria.
