In order for a Mobile Device (MD) to support the Licensed Shared Access (LSA), the MD should be reconfigurable, meaning that\nthe configuration of a MD must be adaptively changed in accordance with the communication standard adopted in a given LSA\nsystem. Based on the standard architecture for reconfigurableMD defined inWorking Group (WG) 2 of the Technical Committee\n(TC) Reconfigurable Radio System (RRS) of the European Telecommunications Standards Institute (ETSI), this paper presents\na procedure to transfer control signals among the software entities of a reconfigurable MD required for implementing the LSA.\nThis paper also presents an implementation of a reconfigurable MD prototype that realizes the proposed procedure. The modem\nand Radio Frequency (RF) part of the prototype MD are implemented with the NVIDIA GeForce GTX Titan Graphic Processing\nUnit (GPU) and the Universal Software Radio Peripheral (USRP) N210, respectively. With a preset scenario that consists of five\ntime slots fromdifferent signal environments, we demonstrate superb performance of the reconfigurableMD in comparison to the\nconventional nonreconfigurable MD in terms of the data receiving rate available in the LSA band at 2.3ââ?¬â??2.4GHz.
