1. A method performed by a wireless communication device configured for use in a wireless communication system, the method comprising:
receiving, from an access node in the wireless communication system, 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 relative target link configuration with respect to a source link configuration, the relative target link configuration comprising one or more parameter values that are different between an absolute target link configuration and the source link configuration, and excludes one or more parameter values that are the same between the target link configuration and the source link configuration; and
the command indicates the condition to be fulfilled in order to perform the link switch;
storing information, the information corresponding to the received target link configuration relative to the source link configuration, wherein the stored information is associated with the condition such that the absolute target link configuration can be determined based on the stored information at the time the condition is fulfilled; and
responsive to fulfillment of the condition, performing the link switch from the source link to the target link using the target link configuration as determined from the stored information.
