Research on high capacity technique based on inter-cell radio resource management for next generation cellular mobile communication systems

针对下一代移动通信系统，研究了小区间载波聚合(CA)方案，该方案将周围多个基站提供给用户设备的多个分量载波聚合在一起。提出了使用扩频传输的基本控制方案、分组调度方案和增强控制方案作为小区间CA的关键机制。计算机仿真结果表明，提出的方案改善了用户吞吐量和传输时延性能，降低了空间非均匀业务环境下通信质量的不一致性。

This research investigates the inter-cell carrier aggregation (CA) scheme, which aggregates multiple component carriers provided by multiple surrounding base stations to user equipments, for next generation mobile communication systems. The basic control scheme, packet scheduling scheme, and enhanced control scheme using spectrum spread transmission are proposed as a key mechanism for the inter-cell CA. These proposed schemes are evaluated by computer simulation and the results show that the proposed schemes improve user throughput and transmission delay performance, and also reduce the non-uniformity in communication quality under spatial non-uniform traffic environments.
