4G/5G UL Inter-Cell Interference Randomization Feature

4G/5G – DL/UL Inter-Cell Interference Randomization Brief Description and expected benefits:

  • When the Cell Load is low; the g-NB.(Scheduler) staggers the resources allocated to adjacent cells as far away from each other as possible in multi-cell networking scenarios.
  • Usually the resources allocation will be staggered based on the PCI(i.e Mod3). However vendors can offer different implementation algorithms.
  • This reduces interference from neighboring cells to UEs in the local cell and improves downlink system capacity and cell edge UE throughput when the network is moderately or lightly loaded.
  • Increases the spectral efficiency, percentage of high-order modulation and coding schemes (MCSs)
  • Decreases Service Drop Rate

  • The network is moderately or lightly loaded. (PRB <40%)
  • In heavy load scenarios, this feature may deliver no benefits. However, it does not generate negative results.

How to Evaluate ❓

  • Evaluate MCS KPIs.
  • DL/UL User and Cell Throughput.
  • Average UL Interference.
