  • Patent number: 11843938
    Abstract: Embodiments herein relate to a method performed by a first communication node operating in a wireless communications network. The first communication node adjusts a value of a Contention Window, CW, from a first value to a second value, the second value being a higher value than the first value, wherein adjusting the value is based on: one or more feedback timers having expired at a time of performing a sensing procedure in the absence of: a) a received uplink, UL, grant from a second communication node, or b) a downlink feedback from the second communication node for an Autonomous Uplink, AUL, transmission from the first communication node. Following adjusting the value, the first communication node initiates a sensing procedure performed prior to a transmission of an UL burst to the second communication node, wherein the sensing procedure uses the adjusted value of the CW.
