BFWAtg - Guard Bands 28GHz

BFWAtg - Guard Bands 28GHz. Draft 26GHz Recommendation: Two FDD systems At least one 28MHz “slot” or single polarisation only in adjacent slots. Two TDD or TDD/FDD mix Two 28MHz “slots” required. Or: No guard bands but “edge slots” and mutual co-operation. BFWAtg(00)20.

  1. BFWAtg - Guard Bands 28GHz • Draft 26GHz Recommendation: • Two FDD systems • At least one 28MHz “slot” or single polarisation only in adjacent slots. • Two TDD or TDD/FDD mix • Two 28MHz “slots” required. • Or: • No guard bands but “edge slots” and mutual co-operation. BFWAtg(00)20

  2. BFWAtg-Guard Bands 28GHz • TM4 Work Item DETR/TM04069: • Two TDMA/FDD systems, 28MHz channels: • No guard band with site sharing • No guard band with near site sharing but better NFD required. • One 28MHz guard channel required for unco-ordinated deployment. • Contd…….

  3. BFWAtg-Guard Bands 28GHz • TM4 Work Item DETR/TM04069: • One TDMA/FDD and one FDMA system, 28MHz channels: • One guard channel with site sharing. • One guard channel with near site sharing. • Two 28MHz guard channels required for unco-ordinated deployment.

  4. BFWAtg-Guard Bands 28GHz • RA/Aegis Study: • Two systems with similar characteristics: • One guard channel required. • Two dissimilar systems (i.e.different channelisation). • One guard channel in each assignment, but mutual co-operation and co-ordination may allow some use.

  5. Summary • Guard channel = 0 • Mutual co-operation reqd including site sharing/near site sharing, tighter NFD’s needed. • Guard Channel = 1 • Unco-ordinated deployment, dissimilar multiple access, similar FDD systems. • Guard channels = 2 • Unco-ordinated dissimilar multiple access, TDD or TDD/FDD mix

  6. Summary • Therefore for maximum protection and greatest freedom for deployment, 2 guard channels would seem appropriate. • For greatest spectrum use “Edge Bands” / co-operation zones seem appropriate but co-operation must take place. • Could depend on the size of assignments.
