This clause captures evaluation results for multiple active CDRX configurations for multiple XR traffic flows.

• Ericsson and InterDigital evaluated the multiple active CDRX configurations separately for XR video and the other traffics.
• vivo compared multiple active CDRX configurations and a single active CDRX configuration with SPS or a single active CDRX configuration only.

Based on the evaluation results in Table B.2.8-1, the following observations can be made:

• For FR1, DL + UL joint evaluation, DU, high load, VR 30Mbps traffic at 30fps with 10ms PDB and DL audio with 10ms PDB, it is observed from Ericsson that:
  • eCDRX with a single CDRX configuration provides:
    • power saving gain of 18.4% for all UEs
    • capacity gain of -100%
  • Multiple CDRX configurations + eCDRX provides:
    • power saving gain of 13.4%
    • capacity gain of -6.0%
  • Multiple CDRX configurations + eCDRX + two-stage DRX provides:
    • power saving gain of 17.2%
    • capacity gain of -13.0%

Based on the evaluation results in Table B.2.8-2, the following observations can be made:

• For FR1, DL + UL joint evaluation, DU, high load, VR 45Mbps traffic at 30fps with 10ms PDB and DL audio with 10ms PDB, it is observed from Ericsson that:
  • eCDRX with a single CDRX configuration provides:
    • power saving gain of 12.3% for all UEs
    • capacity gain of -100%

  • Multiple CDRX configurations + eCDRX + two-stage DRX provides:
    • power saving gain of 13.1%
    • capacity gain of -20.9%
