Abstract:
1. A method of managing bandwidth requests at a relay station (RS) in a wireless telecommunications network, wherein the RS comprises first and second sending units, the method comprising: receiving a first bandwidth request and a ranging code sent by a subordinate network entity; judging whether the RS has sufficient bandwidth available for accommodating the first bandwidth request sent from the subordinate network entity; sending the first bandwidth request to the first sending unit via a first message when the RS has sufficient bandwidth available for accommodating the first bandwidth request; sending the first bandwidth request to the second sending unit via a second message when the RS has insufficient bandwidth available for accommodating the first bandwidth request; sending the received ranging code to the first sending unit via a third message when the RS has sufficient bandwidth available for accommodating the first bandwidth request; sending the received ranging code to the second sending unit via a forth message when the RS has insufficient bandwidth available for accommodating the first bandwidth request; sending by the first sending unit, in response to the first message, a second bandwidth request to a superordinate network entity, wherein the second bandwidth request includes the content of the first bandwidth request; sending by the first sending unit, in response to the third message, a third bandwidth request to the superordinate network entity, wherein the third bandwidth request includes the content of the ranging code sent by the subordinate network entity; and sending by the second sending unit, in response to the second or fourth message, the ranging code to the superordinate network.
