-
- A NETCONF client should configure the value according to the
- configuration of the PHY layer and/or C/U plane section types
- supported and/or any fault tolerant operation. For example,
-
- i) when opertaing with an O-DU supporting non-LAA LTE, this value can
- be configured to a value according to the repetition time of
- transmitted reference symbols across the fronthaul interface
- ii) when opertaing with an O-DU supporting C-Plane Section Type 0,
- this value can configured to a value according to the minimum
- repetition interval of section type 0.
- iii) when operating with an O-DU supporting fault tolerant operation,
- this value can be configured according to the fault tolerant heartbeat
