Abstract
In some embodiments of the invention, a method is provided in a wireless communication device (110) for transmitting an alarm signal to a radio access node (120). According to this method, the wireless communication device (110) detects (210) jamming of a downlink signal (160) which is transmitted from the radio access node (120). The wireless communication device (110) then transmits (220) an alarm signal (150) over a non cell-specific contention-based uplink radio channel. The alarm signal (150) comprises information relating to an identity associated with the wireless communication device (110). The parameters required for transmitting on the non cell-specific contention-based uplink radio channel are preconfigured in the wireless communication device (110).
