The disclosure discloses a method for predictive reception of physical layer downlink repetitions in NB-IoT UE. The object of the disclosure to find a method that prolongs the battery lifetime of IoT devices will be achieved by a method for predictive reception of physical layer downlink repetitions in NB-IoT devices, the method comprising the following steps: estimating an expected number of repeated sub-frames required for a successful reception of a current encoded and in sub-frames rate-matched downlink transmission from a base station to an IoT device by applying a redundancy estimation function, using the estimated expected number of repeated sub-frames as input of a repetition reception control function, where a feedback-loop between the redundancy estimation function and the repetition reception control function is used for refining and adapting the predictive reception of physical layer downlink repetitions in NB-IoT.
