METHOD AND APPARATUS FOR DEVICE-TO-DEVICE (D2D) MOBILITY IN WIRELESS SYSTEMS |
摘要 |
A method and apparatus for mobility for device-to-device (D2D) communications is disclosed. A WTRU may store a proximity detection configuration that includes a measurement object corresponding to at least one discovery signal property, perform a proximity detection measurement to detect a discovery signal property, and then establish D2D communication. A radio resource control (RRC) Measurement Report may be received from a WTRU. Methods for D2D mobility procedures are also disclosed including mobility to or from a direct path, to or from a local path, to or from an infrastructure path, changing serving cell, and cell reselection. Other embodiments include: behavior upon mobility failure, radio link failure, and direct link failure. Security configuration and activation methods and apparatuses are also disclosed. Network methods for inter-eNB management are also disclosed. Finally, direct path proximity detection measurements and methods and apparatuses for triggering and establishing D2D sessions are disclosed. |
