Manage Access Points

The AP (eNodeB in 4G networks and gNodeB function in 5G networks) handles the air interface for the UE. For core services, each AP connects to an Onyx Edge. For SAS-based spectrum access, a CBSD (Citizens Broadband Radio Service Device) resource is created for each AP. The AP represents the radio (gNodeB), while the CBSD represents the same radio in the SAS ecosystem for spectrum coordination. Each CBSD is associated with a single AP. CBSDs do not directly contact the SAS; the Domain Proxy communicates with SAS on behalf of CBSDs, handling registration, spectrum inquiry, grant requests, and heartbeat messages.

CBSD vs AP

AP (Access Point / gNodeB)
- Handles radio transmission and UE connectivity
- Part of the mobile network (RAN)
CBSD
- Represents the AP in the SAS ecosystem
- Handles:
  - Registration
  - Spectrum inquiry
  - Grant management
Relationship
- One AP ↔ One CBSD
- CBSD gets spectrum grants from SAS
- AP uses those grants to transmit
Domain Proxy (DP)
- Communicates with SAS on behalf of CBSDs

Carrier Modes

NOTE: In the current release, Dual Carrier (DC) and Carrier Aggregation (CA) modes are not supported in 5G networks. 5G APs support only Single Carrier (SC) mode.

Single Carrier (SC) Mode – In SC mode, APs use a single carrier frequency, making it suitable for smaller networks or areas with lower traffic where bandwidth needs can be met with one frequency. SC mode is often used for basic services with lower data rates. While it performs well in environments with limited spectrum, it may become less effective as data demands grow. APs in SC mode operate as a single cell (single carrier) and support up to 96 active UE per AP.

NOTE: All carrier mode configurations required on the AP equipment Local Configuration Interface (LCI) are managed by GXC. For queries, please contact GXC Technical Support.

Suspended Grant Handling

When a grant is suspended, spectrum inquiry is initiated to seek a new grant. If a new grant is chosen, the suspended grant is relinquished immediately, and a grant request is sent for the chosen new grant.

In single grant scenarios:
- If a new grant is available, it is chosen, and the suspended grant is relinquished.
- If no new grant is available, the suspended grant is maintained.
In dual grant scenarios:
- If both grants are suspended:
  - If two new grants are available, they are both chosen, and the suspended grants are relinquished.
  - If only one new grant is available, the new grant is chosen. Depending on the best compatibility with this new grant:
    The better of the two suspended grants is retained, and the other relinquished. Here, better is the one that is first larger in bandwidth size and then contiguous. Preference order or power of grants is not used here to keep the implementation simple. If both grants are equal with respect to both bandwidth size and contiguity, then the lower frequency is chosen first.
    If none of the suspended grants is compatible with the new grant, both the suspended grants are relinquished. If no new grants are available, both suspended grants are retained.
- If only one grant is suspended:
  - If at least two new grants are available:
    Of the possible choice of grants, the best compatible two are chosen (new grant + the existing authorized grant).
    The suspended grant is relinquished.
    If it is not part of the chosen two, the existing authorized grant is also relinquished.
  - If only one new grant is available and it is compatible with the existing authorized grant, it is chosen, and the suspended grant is relinquished.
  - If no such new grant is available, the suspended grant is maintained.

NOTE: The suspended grant is relinquished immediately, and a grant request is sent for the chosen new grant. However, the SAS may reject the grant request, leaving the CBSD bereft of grants.

NOTE: It is expected that the SAS does not include currently issued grants (be it granted, authorized, or suspended) as part of available channels, especially when it is suspended. If the suspended grant is part of the available channel, then the same suspended channel/grant may be chosen. It is also possible that some other channel will be chosen. There is no guarantee that another channel will be tried instead of the suspended grant.

NOTE: Since Spectrum Inquiry is now initiated as long as there are suspended grants, to avoid continuous Spectrum Inquiry, a Spectrum Inquiry is sent only five minutes after the previous Spectrum Inquiry.
