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.

Abstract: A method and apparatus for configuring a Long Term Evolution (LTE)-controlled Wireless Local Area Network (WLAN) interface for a wireless transmit/receive unit (WTRU) are described. A method includes receiving LTE Radio Resource Configuration (RRC) signaling that provides parameters for the WTRU to configure the LTE-controlled WLAN interface. The LTE RRC signaling includes a set of WLAN access points (APs), an indication that the WTRU is permitted to autonomously initiate association with a WLAN within the set, a type of one or more bearers to use for the LTE-controlled WLAN interface, WLAN-related security information, and a configuration for the WTRU to report a status of an association with a WLAN AP. The WTRU selects a WLAN AP to associate to from the list and initiates association to the selected WLAN AP using at least the WLAN-related security information.

Abstract: Method and apparatus for providing information to a network are disclosed. An eNodeB (eNB) may receive pattern information relating to connection state management behavior of a wireless transmit/receive unit (WTRU). The eNB may receive this information over S1 signaling when a connection is established. The eNB may determine a time factor for connection state management, wherein the time factor may be based on the received information. The determine time factor may be used to adjust connection states of the WTRU.
