The way users can do research & run simulations on the DRX Mechanism would briefly be as follows -

  1. Define and set the DRX parameters to be used (Ref: drx-config structure under MAC-MainConfig) 
  2. Users can write their own algorithm to turn the UE state to OFF / ON (Sleep / Active)  
  3. In the eNBs MAC Scheduler if node is OFF, do not schedule data. Wait until the UE is turned ON
