Abstract

The present invention relates to a method for transmitting of data frames from user equipment to a base station in a wireless telecommunication network. The method comprises an error control step adapted to retransmit the data frame from the user equipment to the base station, if the received data frame contains errors or if no acknowledge message is received by the user equipment within a predetermined amount of time. The method further comprises a transmission power control step adapted to control a transmission power of the data frames in such a way that the number of retransmissions corresponds to a predetermined number of target retransmission. The number of target retransmission is adapted depending on the traffic load and/or the number of users connected to the base station.
