Systems and methods are described for QoS procedures supporting verticals in wireless systems. Data flows may combine or remap for QoS remapping conditions or state transitions. Data flow remapping may be indicated by triggering a B SR/SR or by multiplexing in the PDU. A non-default set of LCP parameters may be applied for an LCH after a QoS state transition, QoS remapping trigger, or LCP parameter suspension/override. A WTRU may operate according to a QoS adaptation state corresponding to a set of parameter values for a group of data flows, radio bearers, and/or logical channels. A WTRU may transition between QoS adaptation states. An RRC configuration and/or a MAC function may adapt to changing QoS requirement(s). QoS requirement(s) may adapt to changing MAC functions. QoS may be associated with survival time(s). QoS may adapt to higher layer indications. Packet forwarding may adapt to QFI in DL for QoS state changes.
