Are the cell level logical channel ids different from what is mentioned in the spec for LTE?

Hello Experts,
Are the cell level logical channel ids different from what is mentioned in the spec for LTE?
For example, in 36.321 the lcid for ccch is 0 while in Mavenir eNB the lcid for ccch is 4. Is it allowed?
If yes, then where can I find the cell level lcid definition?
