Abstract:
1. A method for transmitting of data frames from a user equipment to a base station in a wireless telecommunication network, said method comprising: retransmitting a particular data frame from the user equipment to the base station, if a previously received version of the particular data frame contains errors or if no acknowledge message is received by the user equipment within a predetermined amount of time in regard to a previously transmission of the particular data frame, and controlling a transmission power of data frames generally by increasing the transmission power, if an actual number of retransmissions is larger than a target number of retransmissions and decreasing the transmission power, if the actual number of retransmissions is smaller than the target number of retransmissions, wherein the target number of retransmissions is set as a function of a number of users connected to the base station, wherein the target number of retransmissions is increased if the number of users connected to the base station increases and wherein the number of users connected to the base station is determined according to an average size of transport blocks received by a radio network controller connected to the base station, wherein the average size of the transport blocks is determined by calculating a moving average of the size of the transport blocks by applying exponential smoothing.
