参数名称 | 取值 | 注释 |
CBTC扇区中心角 | 90°、270° | 每个小区2个扇区 |
GSM/McWiLL基站扇区中心角 | 30°、150°和270° | 每个小区3个扇区 |
McWiLL单小区内McWiLL终端数或LTE FDD终端数/个 | 20 | 实际情况中,单小区的终端数可能远大于20个。考虑激活率/同时在线率,为减小仿真复杂度,这里设单小区同时在线终端数为20个 |
CBTC小区列车数/个 | 6(500 m小区半径)6(450 m小区半径) | 单CBTC基站最大支持6辆列车,单CBTC小区最大覆盖范围为500 m |
6(400 m小区半径)4(350 m小区半径)4(300 m小区半径)2(250 m小区半径)2(200 m小区半径) | 参考北京16号线列车数据[ | |
CBTC列车速度/( km·h-1) | 120 | 城区城铁最大速度为120 km/h |
LTE FDD终端和McWiLL终端速度/(m·s-1) | 1.5 | 行人步行速度 |
CBTC系统单RB带宽/ kHz | 375 | 参见参考文献[ |
CBTC基站/GSM基站/McWiLL基站天线下倾角 | 15° | 参见参考文献[ |
CBTC基站调度方式 | RR | 列车控制属于安全范畴,不适合用PF调度方法 |
McWiLL系统上下行时隙占比 | 1:3(上行:下行) | TDD机制,上下行时隙配比 |
列车和BS最小距离/m | 5 | 两铁轨间距的1/2 |
列车和列车之间横向最小距离/m | 10 | 以北京13号线为例,两轨之间间距为10 m |
列车和列车之间纵向最小距离/m | 200 | 设安全制动距离需200 m |
干扰方对受扰方的ACIR | 见表 6 | 为严格起见,采用确定性计算的方式获得ACIR。通过第3节的确定性计算方法,可以得到GSM和CBTC频率间隔为10 MHz和15 MHz时,GSM基站干扰CBTC终端的ACIR: |
频率间隔10 MHz,CBTC带宽5 MHz时,ACIR=48.9 dB; | ||
频率间隔 10 MHz,CBTC 带宽 10MHz时,ACIR=46.07 dB; | ||
频率间隔15 MHz,CBTC带宽5 MHz时,ACIR=48.58 dB |
