Abstract
A method for radio communication. The method includes: receiving at least one conditional handover execution condition for conducting a conditional handover; determining at least one future QoS that characterizes a quality of at least one radio channel between a radio terminal and a radio access node for at least one future time instant; and evaluating the at least one handover condition based at least on the at least one future QoS.
Claims11
A method performed by a radio terminal for managing a handover from a serving cell associated with a serving radio access node to at least one candidate cell associated with at least one candidate radio access node, comprising:
- receiving at least one handover execution condition for conducting the handover;
- determining at least one future Quality of Service (QoS) that characterizes a quality of a radio channel between the radio terminal and the serving radio access node or the at least one candidate radio access node for at least one future time instant, wherein the determining is based on inputs comprising:
- a motion information that characterizes a relative motion of the radio terminal to the serving radio access node;
- a further motion information that characterizes a relative motion of the radio terminal to the at least one candidate radio access node;
- and
- a spatial position of the serving radio access node and/or the at least one candidate radio access node and a plurality of waypoints with associated time instants representing a movement of the radio terminal;
- and
- evaluating the at least one handover execution condition based at least on the at least one future QoS.
An apparatus for managing a handover from a serving cell associated with a serving radio access node to at least one candidate cell associated with at least one candidate radio access node, comprising:
- a receiver configured to receive at least one handover execution condition for conducting a handover from a serving cell associated with a serving radio access node to at least one candidate cell associated with at least one candidate radio access node;
- a determining device configured to determine at least one future Quality of Service (QoS) that characterizes a quality of a radio channel between the apparatus and the serving radio access node or the at least one candidate radio access node for at least one future time instant, wherein the determining is based on inputs comprising:
- a motion information that characterizes a relative motion of the radio terminal to the serving radio access node;
- a further motion information that characterizes a relative motion of the radio terminal to the at least one candidate radio access node;
- and
- a spatial position of the serving radio access node and/or the at least one candidate radio access node and a plurality of waypoints with associated time instants representing a movement of the radio terminal;
- and
- an evaluator configured to evaluate the at least one handover execution condition based at least on the at least one future QoS.
A non-transitory machine-readable storage medium in a radio terminal on which is stored a computer program for managing a handover from a serving cell associated with a serving radio access node to at least one candidate cell associated with at least one candidate radio access node, the computer program, when executed by a processor, causing the processor to perform the following steps:
- receiving at least one handover execution condition for conducting the handover;
- determining at least one future Quality of Service (QoS) that characterizes a quality of a radio channel between the radio terminal and the serving radio access node or the at least one candidate radio access node for at least one future time instant, wherein the determining is based on inputs comprising:
- a motion information that characterizes a relative motion of the radio terminal to the serving radio access node;
- a further motion information that characterizes a relative motion of the radio terminal to the at least one candidate radio access node;
- and
- a spatial position of the serving radio access node and/or the at least one candidate radio access node and a plurality of waypoints with associated time instants representing a movement of the radio terminal;
- and
- evaluating the at least one handover execution condition based at least on the at least one future QoS.
