摘要

由Macrocell部署和覆盖Picos组成的异构网络(HetNet)为提高Macrocell容量和覆盖范围提供了一种有吸引力的方法。然而，在这种两层系统中，从Macrocell到Pico的层间干扰会显著降低Pico的覆盖范围，造成系统容量损失。因此，3GPP提出了基于Macrocell的Cell Range Expansion (CRE)和Almost Blank Subframe (ABS)配置来提高Pico的覆盖范围。在此背景下，提出了一种能够满足Pico用户设备SINR要求的Pico专用CRE偏置上界估计算法。

A method for pico-specific upper bound CRE bias setting in HetNet

Heterogeneous Networks (HetNet) consisting of Macrocells deployment and overlaying Picos provide an attractive way to improving the Macrocell capacity and coverage. However, the inter-tier interference from Macrocell to Pico in such two-tiers system can significantly reduce the coverage of Pico and cause the system capacity loss. So, the Cell Range Expansion (CRE) for Pico with Almost Blank Subframe (ABS) configuration for Macrocell is proposed in 3GPP to improve the coverage of Pico. Based on this background, we proposed an estimation algorithm for Pico-specific upper bound CRE bias calculation which can ensure the SINR requirement for Pico User Equipments (PUEs).
