1. A client device, comprising:
at least one processor; and
a non-transitory computer-readable storage medium having computer readable instructions stored thereon that, when executed by the at least one processor, cause the client device to:
obtain a first indication indicating an outcome of a link monitoring procedure associated with a serving link between a network access node and the client device;
obtain a second indication indicating an outcome of a link re-configuration procedure associated with the serving link;
determine a value of a first counter associated with a radio link failure timer based on the first indication and the second indication; and
start the radio link failure timer when the value of the first counter is equal to or larger than a first counter threshold value;
determine a value of a second counter associated with the radio link failure timer based on the first indication and the second indication;
reset the radio link failure timer when the value of the second counter is equal to or larger than a second counter threshold value; and
decrease the value of the first counter by an amount defined by a first decrement function when the second indication indicates a successful outcome of the link re-configuration procedure,
wherein the first decrement function comprises one of:
a reset of the value of the first counter to zero when a number of consecutive second indications indicating a successful outcome of the link re-configuration procedure are obtained, wherein the number of consecutive second indications is dependent on a first decrement function variable; or
a reset of the value of the first counter to zero when a number of non-consecutive second indications indicating a successful outcome of the link re-configuration procedure are obtained, wherein the number of non-consecutive second indications is dependent on the first decrement function variable.
