[Uma]: Obviously, the best reference for GTP-U is TS 29.281. However, uou
should look into
https://datatracker.ietf.org/doc/draft-ietf-dmm-5g-uplane-analysis/ where
lot more details and other references related this topic was analyzed
(primarily started after/during REL-15, when  any other use plane other
than GTP-U is worthwhile is debated for 5G N9 interface).
