5G • 5G-Advanced (Rel-18)
10 MHz Satellite Channelization
Dedicated Narrowband Channelization for Satellite Spectrum
Tailors 5G radio channels for narrow 10 MHz MSS and FSS satellite spectrum blocks, ensuring maximum spectral efficiency over space links.
Technical Explanation
Commercial satellite spectrum allocations in S-band, L-band, and Ku-band are significantly narrower than terrestrial 100 MHz carriers. Rel-18 standardizes dedicated 10 MHz channel profiles for NR-NTN, optimizing control channel search spaces, synchronization rasters, and reference signal overhead to fit tightly inside satellite regulatory bandwidth caps.
Key Functions
- Optimizes physical layer numerologies for narrow 10 MHz and 5 MHz satellite carriers
- Fits commercial 5G-Advanced protocols into standard ITU satellite frequency allocations
- Minimizes guard band wastage while satisfying international satellite emission masks
- Enables global mobile operators to partner with satellite fleet operators seamlessly
Specifications
3GPP TS 38.101-5, TS 38.211 (Rel-18)
Interfaces
