Abstract: Wireless communication equipment (18) is configured for use in a wireless communication network (10). As listen-before-talk, LBT, attempts occur over time on a transmission resource (16-1 . . . 16-N), the wireless communication equipment (18) makes updates to a performance rating (22-1 . . . 22-N) for the transmission resource (16-1 . . . 16-N) to reflect an observed likelihood of LBT pot attempt success or failure on the transmission resource (16-1 . . . 16-N). Responsive to a failed LBT attempt on the transmission resource (16-1 . . . 16-N) occurring unexpectedly according to the performance rating (22-1 . . . 22-N), the wireless communication equipment (18) applies a bias (26-n) to the performance rating (22-1 . . . 22-N) to reflect a greater likelihood of LBT attempt failure, or a smaller likelihood of LBT attempt success, than actually observed on the transmission resource (16-1 . . . 16-N), and relaxes the applied bias (26-n) over time.
