B.2.13  Non-scheduling DCI based PDCCH skipping and continuous PDCCH skipping  p. 110

This clause captures evaluation results for non-scheduling DCI based PDCCH skipping and UE continuous PDCCH skipping:
  • CATT evaluated non-scheduling DCI based PDCCH skipping indication to reduce unnecessary PDCCH monitoring when no XR data is scheduled for transmission. On top of this, gNB configures a short PDCCH skipping duration and UE continuously skips the PMOs until the DCI is successfully decoded at the time of packet arrival.

Based on the evaluation results in Table B.2.13-1, the following observations can be made:
  • For FR1, DL-only evaluation, InH, high load, VR 30Mbps traffic at 60fps with 10ms PDB, it is observed from CATT that the:
    • non-scheduling DCI based PDCCH skipping with persistent skipping indication provides:
      • mean power saving gain of 22.4% w.r.t. Always-On
      • mean capacity gain of -6.4% w.r.t. Always-On
      • mean power saving gain of 15.7% w.r.t. DG scheduling with C-DRX(16, 12, 4)
      • mean capacity gain of -0.33% w.r.t. DG scheduling with C-DRX(16, 12, 4)
    • go-to-sleep indication scheme with C-DRX(16, 12, 4) provides:
      • mean power saving gain of 24.0% to 24.4% w.r.t. Always-On
      • mean capacity gain of -6.1% w.r.t. Always-On
      • mean power saving gain of 17.4% to 17.8% w.r.t. DG scheduling with C-DRX(16, 12, 4)
      • mean capacity gain of 0% w.r.t. DG scheduling with C-DRX(16, 12, 4)
    • non-scheduling and scheduling DCI with continuous PDCCH skipping and dynamic go-to-sleep indication provides:
      • mean power saving gain of 29.4% to 29.9% w.r.t. Always-On
      • mean capacity gain of -6.4% w.r.t. Always-On
      • mean power saving gain of 23.3% to 23.8% w.r.t. DG scheduling with C-DRX(16, 12, 4)
      • mean capacity gain of -0.33% w.r.t. DG scheduling with C-DRX(16, 12, 4)
    • DG scheduling with C-DRX(16, 12, 4) as the performance reference provides:
      • mean power saving gain of 8% w.r.t. Always-On
      • mean capacity gain of -6.1% w.r.t. Always-On
