Abstract
The present invention relates to an apparatus for transmitting and receiving signals in a wireless telecommunication system and to a method for transmitting random access bursts in such an apparatus. The apparatuscomprises transmitting meansfor transmitting random access bursts, receiving meansfor receiving acknowledgement information confirming a successful transmission of a random access burst, decision means for deciding if acknowledgement information has been received, and control meansfor randomly choosing a time point for an attempt to retransmit said random access burst from an interval if no acknowledgement information has been received after a random access burst had been transmitted, whereby the control means sets the length of the interval depending on the number of unsuccessful attempts to transmit a random access burst. The proposed backoff scheme provides an improved performance and increased system stability without the need for a collision detection on the network side. Further, the proposed backoff scheme supports different priority classes for the transmission of random access bursts.
