6.4.1 Larger Channel BW than licensed BW p. 29
Does not require new channel filters for UE to be designed and tested.
6.4.2 Overlapping UE CBW from Network Perspective p. 29
This approach can be also be applied to all irregular channel bandwidths with only consideration of different spectral utilization considerations. However the single CORESET#0 and SSB is only applicable for bandwidths greater than 10 MHz. For all irregular channel bandwidths two SSBs can be used (in irregular channel bandwidths < 10 MHz SSB can be TDM).
Does not require new channel filters for UE to be designed and tested.
6.4.3 Combined UE CBW (one cell) p. 29
- Given the availability of a new UE with the required architecture, a future proof solution, the channel bandwidth can be tailored with the resolution of 1PRB. Able to support any irregular channel bandwidth even to the band edge.
- Ensured co-existence with very limited specification impact since both the "main RF carrier" and the "additional RF carrier" and the separate signal processing paths before the equalization would conform to existing 3GPP requirements
- Does not require new channel filters for UE and gNB to be designed and tested
6.4.4 Combined UE CBW (two cell) p. 29
This approach can be applied to various size of irregular channel bandwidths, and it does not require to define new channel filters to be designed and tested for BS and UE.
Does not require new channel filters for UE to be designed and tested.
