3.8. Scheduling
Small Cell supports QoS scheduling (conforming to QCI priority, GBR and MBR for GBR bearer, UE-
AMBR for Non-GBR bearer) and PF (Proportional fairness) scheduling for Non-GBR bearer.
3.9. ANR (Automatic Neighbor Relation)
Small Cell can automatically update for neighbor cell’s information such as Physical Cell ID, Cell
Global ID, Tracking Area Code and etc. Neighbor cell information obtained through ANR can be used
for handover and HeMS management
Small Cell supports 3 kinds of ANR methods
- NL (Network Listening) based ANR
- UE based ANR
- X2 based ANR
3.10. CBRS (Citizen Broadcast Radio Service)
3.10.1.
CBSD (Citizen Broadcast Radio Service Device)
Small Cell supports CBSD – SAS (Spectrum Access System) protocol in CBRS. CBSD function in Small
Cell complies with WINNF CBRS standards and supports multiple grants to activate one or more cells.
The small cell device acts as CBSD in CBRS. In order to start service, CBSD needs grant(s) allocated
from SAS. One grant consists of information related to channel configuration, e.g. bandwidth, max
EIRP (Effective Isotropic Radiated Power). After stored Grants, CBSD should set configuration following
grant information. Following figure describes small cell network diagram with CBRS.
