Systems and methods of a probing beam procedure are provided. In some embodiments, a method performed by a User Equipment (UE) for evaluating candidate beam pair links includes: indicating support for probing Uplink (UL) Reference Signal (RS) during capability signaling; determining a spatial filter for a UL-RS transmission based on one or more Downlink (DL) Reference Signals (DL-RSs); updating the spatial relation of a UL-RS; and transmitting UL-RS directly without a need of explicit spatial relation update for the UL-RS from a network node. In this way, some embodiments enable the network to evaluate candidate beam pair links based on a UL-RS transmission of a UE, without the need to explicitly indicate spatial filter that the UE shall use for the UL-RS transmission. Some embodiments describe several solutions on how to perform the methods with reduced UL-RS overhead by letting the UE help when to trigger the UL-RS transmission.
