Abstract: Embodiments of the present disclosure relate to device, method, apparatus and computer readable storage media of reactive jamming detection. The method comprises in accordance with a determination that an interference to the first device is to be detected, determining at least one set of actual receiving powers at the first device on a bandwidth and a frequency of a channel associated with a transmission of the first device within a time interval; determining at least one set of reference receiving powers at the first device on the bandwidth and the frequency; and in accordance with a determination that a difference between the at least one set of reference receiving powers and the at least one set of actual receiving powers exceeds a threshold difference, determining the first device is interfered by reactive jamming. In this way, the malicious device that does not respect the LBT procedure in unlicensed bands can be recognized and meanwhile the devices using a different technology while respecting the LBT procedure can be allowed to access the channel.
