1. A method for determining a Physical Uplink Control Channel (PUCCH) resource for transmitting an uplink (UL) control signal, the method comprising:
receiving at least one physical resource configuration for transmitting the UL control signal, the physical resource configuration comprising an indication of a plurality of PUCCH resources in a frequency domain;
determining a PUCCH resource based on the received at least one physical resource configuration;
adjusting the determined PUCCH resource for transmitting the UL control signal in response to an UL listen before talk (LBT) failure prior to the transmission of the UL control signal, wherein adjusting the determined PUCCH resource for transmitting the UL control signal is based on an outcome of the UL LBT performed before the transmission of the UL control signal, and a time gap between the UL LBT and the transmission of the UL control signal is longer than a predefined threshold; and
transmitting the UL control signal using the adjusted PUCCH resource.
