Abstract
The invention relates to feedback transmission for data packets in a mobile communication system. In particular the invention provides a communication system wherein feedback information of a retransmission protocol for transmitted data packets is transmitted. Further, the invention relates to a method for determining radio resources for the transmission of feedback information of a retransmission protocol for transmitted data packets as well as to a base station and a mobile station performing the method. In order to prevent potential collisions of feedback information while omitting a destination identifier for identifying the receiver of the feedback, the feedback resources for sending the feedback are determined at least based on a current transmission counter for a packet.

57. A method for determining radio resources for the transmission of feedback information of a retransmission protocol for transmitted data packets comprising:
-
determining by a feedback transmission entity a radio resource for transmitting feedback information for a data packet according to a radio resource used for transmitting scheduling information for a first transmission of the data packet and a current transmission number of the data packet, and transmitting the feedback information to a data packet transmission entity transmitting the data packet on the determined radio resource. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67)

68. A mobile terminal in a mobile communication system for receiving feedback information for uplink transmissions of data packets from a base station, the mobile terminal comprising:
-
a receiver for receiving a scheduling grant to the mobile terminal allocating a radio resource for the transmission of uplink data, a transmitter for transmitting a data packet from the mobile terminal according to the scheduling grant, and a processing unit for determining a radio resource based on the current transmission number of the data packet, wherein the receiver is configured to receive feedback information indicating a successful or unsuccessful decoding of the data packet at the base station on the determined radio resource.
