Abstract
A wireless transmit/receive unit (WTRU) may communicate with a serving cell and monitor suitable non-serving cell(s) may be monitored. Uplink-based forward mobility may be performed. The WTRU may transmit control signaling that may indicate an ordered list of candidate target cell(s) using resources of the source cell. A resume procedure towards a non-serving cell may be initiated while in connected state with serving cell. Upon a successful resume in non-serving cell, the connection may be disconnected from the serving cell.

1-20. (canceled)
A wireless transmit/receive unit (WTRU), the WTRU comprising:
- a memory;
- and
- a processor, the processor configured to:
- monitor one or more neighbor cells;
- determine that an egress condition for a source cell and an ingress condition for a target cell have been satisfied, the target cell being a neighbor cell from the one or more neighbor cells;
- send a resume request to the target cell when the egress condition and the ingress condition have been satisfied while maintaining a connection to the source cell;
- suspend one or more of a beam failure recovery procedure associated with the source cell and a radio link failure procedure associated with source cell;
- receive a resume response from the target cell;
- and
- release the connection to the source cell.
A method being implemented in a wireless transmit/receive unit (WTRU) for performing an uplink-based forward mobility, the method comprising:
- monitoring one or more neighbor cells;
- determining that an egress condition for a source cell and an ingress condition for a target cell have been satisfied, the target cell being a neighbor cell from the one or more neighbor cells;
- sending a resume request to the target cell when the egress condition and the ingress condition have been satisfied while maintaining a connection to the source cell;
- suspending one or more of a beam failure recovery procedure associated with the source cell and a radio link failure procedure associated with the source cell;
- receiving a resume response from the target cell;
- and
- releasing the connection to the source cell.
