Abstract: Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.

Abstract: Systems, methods, and instrumentalities are disclosed for connectivity supervision and recovery. A WTRU may supervise its capability to transmit and receive data, including in the absence of a control channel (e.g. grant-less transmission). A supervision framework may permit a WTRU to supervise, for example, quality of a feedback channel, quality of reciprocal resources and/or transmission attempts. A supervision process may be a function of a control channel structure or WTRU state. A supervision process may be associated with a quality of service. A supervision process may be based on WTRU transmission for energy/resource efficient operation. Multiple Recovery procedures may be defined. A recovery procedure may be a function of a supervision process. A recovery procedure may be optimized for low latency services. Recovery procedures may involve dedicated resources for recovery, transition to light connection, grant-less resource, etc. User plane recovery may include reuse of layer 2 context, data replication to companion MAC instances, etc. Control plane recovery may use RAN paging, WTRU triggered multi-connectivity, etc. A recovery procedure for a supervision process associated with a beam process may include WTRU triggering beam training/beam refinement, etc.
