`ABSTRACT
`Systems , procedures , and instrumentalities are disclosed for
`distributed control in wireless systems , such as 5G flexible
`radio access technology ( RAT ) ( 5gFLEX ) . Example proce
`dures are provided for WTRU and network operation asso
`ciated with a distributed control plane architecture , connec
`tionless data transfer and dedicated system information
`acquisition . Distributed control may be provided , for
`example , by replicating a plurality of access control func
`tions ( ACFs ) using a plurality of instances in a plurality of
`different transmission / reception points ( TRPs ) with multi
`connectivity . The plurality of TRPs may concurrently pro
`vide control services to a WTRU . Centralized control func
`tions may manage core network connectivity and / or a
`plurality of user plane instances for the WTRU and / or may
