摘要

3GPP Rel. 10中载波聚合(CA)技术的引入对网络规划提出了新的挑战。如果来自不同频带的非连续载波聚合(即带间CA)发生，则尤其如此。本文分析了不同CA场景下终端接收聚合载波信号时所受到的干扰。数学模型的推导允许干扰，因此，载波干扰比是全局表征。利用ICS-Telecom仿真工具对不同传播模型下的一些数值结果进行了分析。并与理论模型进行了比较。

Interference analysis for inter-band Carrier Aggregation in LTE-advanced

The introduction of Carrier Aggregation (CA) techniques in 3GPP Rel. 10 poses some new challenges on network planning. This is especially true if the aggregation of non-contiguous carriers from different frequency bands (i.e. InterBand CA) occurs. In this paper the interference suffered by a UE when receiving aggregated carrier signals is analysed in different CA scenarios. Mathematical models are derived that allow the interference and, consequently, the Carrier-to-Interference ratio to be globally characterized. Some numerical results using different propagation models are analysed using ICS-Telecom simulation tool. A comparison with the theoretical models is also presented.
