The present disclosure relates to a method used in a radio node and the associated radio node. The method comprises: obtaining a network geometry of a User Equipment (UE) served by the radio node with respect to a coverage served by the radio node; determining a carrier sensing threshold for the UE based on the network geometry, the carrier sensing threshold for use in Listen-Before-Talk (LBT) measurement over a radio frequency band applicable for transmitting data to the UE; and applying the carrier sensing threshold in the LBT measurement. The present disclosure also relates to a method used in a UE and the associated UE, and to a method used in a radio node and the associated radio node.
