5G Dynamic Spectrum Sharing (DSS)
In this course, we take a special look at how DSS works and learn the details for both MBSFN and non-MBSFN-based DSS, including NR PDSCH rate matching around LTE CRS and overhead considerations. We also discuss partial DSS and potential benefits compared to full DSS.

Course Outline:
- The course starts with the motivations for dynamic spectrum sharing (DSS).
- It continues with the following:
- DSS use in LTE MBSFN and non-MBSFN subframes
- DSS in SA and NSA modes
- Comparisons between DSS and spectrum reframing
- NR and LTE overhead in shared channel
- Deployment considerations and recommendations
- There are log analysis exercises for MBSFN and non-MBSFN based DSS procedures, DL/UL control and reference signals, LTE and NR PDSCH/PUSCH sharing, and mobility and RLF recovery.
