Problem delimitation

3 干扰、重叠覆盖、弱覆盖区域、无主导小区四种问题标准,对路测数据进行二次处理; Secondly process drive test data by defining four problem criteria: Modal 3 interference, overlapping coverage, weak coverage area, and no dominant cell;

  • 3 干扰 Mode 3 interference


    Nine tail

RSRP>-100dBm ,邻小区中存在与服务小区模 3 冲突的 PCI ,且冲突小区的 RSRP 与服务小区 RSRP 相差正负 6dBm 时,将这样的点定义为模 3 干扰; When the serving cell RSRP is greater than -100 dBm , there is a PCI in the neighboring cell that conflicts with the serving cell's mode 3 , and the RSRP of the conflicting cell differs by plus or minus 6 dBm from the serving cell's RSRP .

  • Overlapping coverage

RSRP>-90dBm ,且邻小区中存在 2 个以上含两个与服务小区 RSRP 相差正负 6db 的邻区,将这样的点定义为重叠覆盖; When the serving cell RSRP is> -90dBm , and there are more than 2 neighboring cells in the neighboring cell containing two plus or minus 6db from the serving cell RSRP , such a point is defined as overlapping coverage;

  • No dominant cell

-90dBm>RSRP>-105dBm ,且邻小区中存在 2 个以上含两个 RSRP 与服务小区 RSRP 相差正负 6db 的邻区,将这样的点定义为无主导小区; When the serving cell is -90dBm> RSRP> -105dBm , and there are more than 2 neighboring cells in the neighboring cell containing two RSRPs that differ by plus or minus 6db from the serving cell RSRP , such a point is defined as a non-dominant cell;

  • Weak coverage

RSRP<-105dBm 的点定义为弱覆盖区域; When the serving cell RSRP <-105dBm is defined as a weak coverage area;

  • Normal coverage

The remaining areas are defined as normal coverage;

3 干扰可能存在交集,考虑到模 3 干扰对 SINR 影响较大,故优先判定为模 3 干扰。 Note: There may be an overlap between overlapping coverage and Modal 3 interference. Considering that Modal 3 interference has a large impact on SINR , it is prioritized as Modal 3 interference.
