Abstract

In the Third Generation Partnership Project (3GPP) standardization for LTE services in the unlicensed band, i.e., aggregation of LTE on licensed and unlicensed spectrum, known as 'Licensed-Assisted Access using LTE' (LAA), carrier sensing via Listen-Before-Talk (LBT) procedure is a vital feature for fair sharing and friendly operation in the unlicensed spectrum. Meanwhile, along with the recent contribution to performance enhancement with the frequency reuse-1 for Licensed-Assisted Access using LTE (LAA) system, we propose a new scheme, referred to as alignment reference interval adaptation-based LAA (ARIA-LAA), by combining the advantages of each conventional scheme into a unified access framework. Our simulation results demonstrate that ARIA-LAA is a novel scheme of spectrum sharing with spatial reuse for LAA that can increase the overall system capacity while satisfying the fair-coexistence requirement. Its implementation is simple and robust as only a single design parameter is dynamically controlled and optimized for adaptation to the varying traffic load.
