Random access burst transmission scheme
First Claim
1. An apparatus for transmitting and receiving signals in a wireless telecommunication system, the apparatus comprising:
- a transmitter configured to transmit a random access burst;
a receiver configured to receive acknowledgement information confirming a successful transmission of said random access burst;
a decision unit configured to decide if acknowledgement information has been received; and
a controller configured to randomly choose a timepoint for an attempt to retransmit said random access burst from an interval if no acknowledgement information has been received after said random access burst has been transmitted, wherein the controller is configured to set a length of said interval depending on a number of unsuccessful attempts to transmit said random access burst.
