Implementation of reconfigurable mobile device with licensed shared access functionality

Recently, as the heterogeneous network (HetNet) has been deployed widely to support various kinds of Radio Access Networks(RANs) with a combination of Macro, Pico, and/or Femto cells, research and standardization regarding the concept of Licensed Shared Access (LSA) for supporting spectrum sharing have been very actively performed. Especially, Working Group 1 (WG1) of Technical Committee (TC) Reconfigurable Radio System (RRS) of European Telecommunications Standards Institute (ETSI) has been a main driving force for developing a system requirements and use cases for the LSA system, while WG2 has set up a standard architecture of reconfigurable Mobile Device (MD) that can be applied to the LSA system. In this paper, we introduce the reconfigurable MD architecture for supporting LSA-based spectrum sharing. An implementation of a test-bed of reconfigurable MD is presented in order to verify the feasibility of the standard MD architecture for the purpose of LSA-based spectrum sharing through various experimental tests.
