Abstract
A method and apparatus for mobility condition change based on serving cell quality and connection release in a wireless communication system is provided. A wireless device receives information on a first condition related to a conditional mobility to a target cell, detects a serving cell problem, performs the conditional mobility to the target cell based on a second condition related to a cell selection, and performs a connection release with the target cell.
Claims10
A method performed by a wireless device adapted to operate in a wireless communication system, the method comprising:
- evaluating a condition of each of a number of candidate target cells for conditional mobility,
- wherein the condition of each candidate target cell and a configuration of each candidate cell is obtained via a conditional mobility configuration, and
- wherein the condition is configured by one of i) a comparison between a measurement result of each candidate target cell and a measurement result of a serving cell, or ii) a comparison between a measurement result of a serving cell with respect to a first threshold and a comparison between a measurement result of each candidate target cell with respect to a second threshold;
- upon re-configuration with sync failure of a master cell group (MCG), initiating a connection re-establishment procedure;
- upon initiating the connection re-establishment procedure, performing a cell selection;
- based on a selected cell due to the cell selection being one of the candidate target cells, applying a configuration associated with the selected cell;
- receiving a radio resource control (RRC) release message from the selected cell;
- and
- entering an RRC idle state or an RRC inactive state based on the RRC release message,
- wherein the selected cell is selected based on a cell selection criterion S being satisfied for the selected cell.
