1. A method (100) performed by a user equipment, UE, operable to be used in a wireless communication network for transmitting sounding reference signals, SRSs, comprising:

  • -receiving (110) at least one transmission from at least one network node,-measuring (120) at least one radio quality indicator based on the received at least one transmission,-comparing (130) the at least one measured radio quality indicator with at least a first threshold value, and-deciding whether to transmit or refrain from transmitting (140) the SRS based on a result of the comparison,wherein the SRS is transmitted according to a first SRS pattern when the measured value of the at least one radio quality indicator is above the first threshold, the SRS is not transmitted when the measured value of the at least one radio quality indicator is below a second threshold, and the SRS is transmitted according to a second SRS pattern when the measured value of the at least one radio quality indicator is below the first threshold but above the second threshold, and wherein the first threshold is above the second threshold.
