Link switch in a wireless communication system

A wireless communication device configured for use in a wireless communication system, the wireless communication device comprising:

• processing circuitry and a memory, the memory containing instructions executable by the processing circuitry whereby the wireless communication device is configured to:
• receive a command that commands the wireless communication device to perform a link switch from a source link to a target link responsive to fulfillment of a condition, wherein the command indicates a target link configuration relative to a source link configuration, and the command indicates the condition to be fulfilled in order to perform the link switch;
• store information from which the target link configuration indicated by the command is determinable irrespective of any change to the source link configuration occurring after receipt of the command;
• and
• responsive to fulfillment of the condition, perform the link switch from the source link to the target link using the target link configuration as determined from the stored information.

A method performed by a network node configured for use in a wireless communication system, the method comprising:

• transmitting a command that commands a wireless communication device to perform a link switch from a source link to a target link responsive to fulfillment of a condition, wherein the command indicates a target link configuration relative to a source link configuration, and the command indicates the condition to be fulfilled in order to perform the link switch;
• after transmitting the command, changing the source link configuration;
• and
• after changing the source link configuration, transmitting an updated command that indicates an updated target link configuration relative to the source link configuration before the source link configuration was changed.
