Abstract:

Carrier aggregation has been adopted as a key technology in 3GPP LTE-Advanced Release 10 to enable extremely high data rate services. However, due to imperfect implementation, adjacent channel interference (ACI) potentially induces inter-system interference among co-existing systems which can greatly degrade performance. In this paper, we develop an equivalent adjacent channel interference ratio (ACIR) model to simplify the general evaluation of all possible CA coexistence scenarios beyond investigations in Release 10, and our methodology can be applied to wider scenarios including considering both FDD and TDD at the same time. By using this method, our simulation results assure that introducing Carrier Aggregation (CA) technique does not significantly influence the system performance in newest IMT band, 3.5GHz under the current regulations.
