Abstract
The increasing traffic demand will require additional spectrum to be used for mobile broadband. Licensed Shared Access (LSA) is one option for mobile network operators (MNO) to provide access to spectrum resources of other radio services, which are underutilized for specific time intervals and location areas, ensuring interference free coexistence between the sharing partners, i.e. this utilization of the spectrum requires decoupling of the resources in spatial or time domain. Indoor small cell deployments are particularly interesting for such a sharing scenario, due to the additional attenuation from the walls providing additional decoupling of the two systems. This article analyzes the network planning feasibility for LSA spectrum usage in indoor small cell scenarios. On basis of real indoor-to-outdoor propagation measurements and existing propagation models, a minimum decoupling range is determined where the LSA signal penetrating to the outdoor area falls below a certain threshold that guarantees interference free operation of the incumbent.
