摘要 三角形小区通信系统(TCCS)是一种新型分布式基站(BS)通信系统。小区结构为正三角形,分为3个单一覆盖区(UCR)和1个交叉覆盖区(CCR)。移动台(MS)在单一覆盖区内只与邻近的BS通信,在交叉覆盖区内与小区所有3个基站通信。在该小区结构的基础上,该文提出了在单一覆盖区内采用频率复用,在交叉覆盖区内采用宏分集的频率规划方案。在这种规划方案和每根天线最大发送功率限制下,计算了多小区环境下TCCS在MS单天线和多天线时的遍历容量,与相同条件下的广义分布式天线系统(GDAS)作了比较,结果显示在各种情况下,TCCS的容量相对于GDAS都有显著的增益。 Triangular Cell Communication System （TCCS） is a novel distributed Base Station （BS） system. Its cell structure is an equilateral triangle, and it is composed of 3 Uni-Cover Regions （UCR） and 1 Cross-Covered Region （CCR）. Mobile Station （MS） communicates with one near BS in UCR, and communicates with all 3 BSs of the cell in CCR. In this paper, a frequency plan scheme is proposed, which adopts frequency reuse in UCR, and macro diversity in CCR. Under this frequency plan and the per-antenna maximum transmit power constraint, the ergodic capacity of TCCS in multi-cell environment is calculated, and it shows that TCCS offers large capacity gain over Generalized Distributed Antenna System （GDAS）.
