6 Conclusions p. 16
In conclusion of the study, the following enhancements for XR services are recommended:
-
For XR Awareness:
- Provisioning by CN of semi-static information per QoS flow (e.g. PDU set QoS parameters), dynamic information per PDU set (PDU Set information and Identification) and End of Data Burst indication (as per TR 23.700-60);
- Identifying by UE of PDU Sets, Data bursts and PSI;
- Provisioning by UE of XR traffic assistance information e.g. periodicity, UL traffic arrival information (FFS).
-
For Power Saving:
- DRX support of XR frame rates corresponding to non-integer periodicities (through at least semi-static mechanisms e.g. RRC signalling).
-
For Capacity Enhancements:
- Multiple CG PUSCH transmission occasions in a period of a single CG PUSCH configuration;
- Dynamic indication of unused CG PUSCH occasion(s) based on UCI by the UE;
- BSR enhancements including at least new BS Table(s);
- Delay reporting of buffered data in uplink;
- Discard operation of PDU Sets.
