A network node (14) is configured for use in a wireless communication network (10). The network node (14) obtains a value of a metric (22) that indicates a speed at which a wireless communication device (12) moves. The network node (14) also determines. based on the value of the metric (22). how often the wireless communication device (12) is to send a sounding reference signal. SRS. (18), wherein the wireless communication device (12) is to send the SRS (18) more often for at least one value of the metric (22) below a threshold as compared to for at least one value above the threshold. The network node (14) transmits. to the wireless communication device (12), signaling (16) that configures or triggers the wireless communication device (12) to send the SRS (18) as often as determined.
