Patent ID: 7359705

Claim:
A method for transmitting random access bursts in an apparatus for transmitting and receiving signals in a wireless telecommunication system, comprising transmitting a first random access burst with a first priority class, transmitting a second random access burst with a second priority class, said second priority class lower than said first priority class, deciding if first acknowledgement information confirming a successful transmission of said first random access burst has been received, deciding if second acknowledgement information confirming a successful transmission of said second random access burst has been received, randomly choosing a first time point for an attempt to retransmit said first random access burst from within a first interval if no first acknowledgement information has been received, randomly choosing a second time point for an attempt to retransmit said second random access burst from within a second interval if no second acknowledgement information has been received, setting the length of said first interval depending on at least two parameters, whereby a first parameter indicates the number of unsuccessful attempts to transmit the first random access burst and a second parameter indicates the first priority class, and setting the length of said second interval depending on at least two parameters, whereby a third parameter indicates the number of unsuccessful attempts to transmit the second random access burst and a fourth parameter indicates the second priority class, whereby said second and fourth parameters are chosen so that said first interval is set shorter than said second interval.
