Abstract

The invention discloses a method for predictive reception of physical layer downlink repetitions in NB-IoT UE. The object of the invention to find a method that makes it possible to obtain necessary predictions about the receptions of repetitions of data transmitted on the physical layer in order to prolong the battery lifetime of IoT devices will be solved 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, wherein 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.
