Abstract

The subject matter relates to a method for transmitting data in packets in a radio communications system, according to which the receipt of data packets from at least two terminals is confirmed by a base station of the radio communications. The confirmation of receipt takes place without an overlap in time, using identical resources.

Claims

1-10. -10. (canceled)

11. A method for transmitting data in packets in a radio communications system, comprising confirming, by a base station, receipt of data packets received from at least two terminals, with confirmations of receipt taking place without an overlap in time, using identical resources.

12. The method as claimed in claim 11, further comprising configuring the resource for confirmation as a signature.

13. The method as claimed in claim 11, further comprising using at least one bit position or a code sequence in a time interval of a time frame as a resource for confirming the receipt of the data packets of the at least two terminals.

14. The method as claimed in claim 11, wherein the data packets of the at least two terminals are transmitted in an identical physical resource without an overlap in time or in a temporally overlaying fashion.

15. The method as claimed in claim 11, further comprising assigning at least one time interval of a frame to the at least two terminals for transmitting the data packets in each instance.

16. The method as claimed in claim 15, wherein the respective time intervals for the transmission of data packets by a radio network controller and/or the base station are assigned to the at least two terminals in a coordinated fashion such that a confirmation of the receipt can take place without an overlap in time, using the same resources.

17. The method as claimed in claim 15, wherein the time intervals for transmitting data packets to an identical position in at least two consecutive frames are assigned to at least two terminals.

18. A base station of a radio communications system, comprising:

at least one transmitting/receiving facility receiving data packets from at least two terminals and transmitting confirmations of the receipt; and

a control facility controlling transmission of the confirmations without an overlap in time, in an identical resource.

19. The base station as claimed in claim 18, wherein the control facility is configured so as to assign resources to the at least two terminals for the transmission of data packets in the uplink direction and to assign the same resource for the transmission of confirmations in the downlink direction to the at least two terminals.

20. A radio communications system, comprising:

a radio network controller having at least one control facility assigning resources to at least two terminals for transmitting data packets in an uplink direction to at least one base station, and a transmitting/receiving facility transmitting the assignment to the at least two terminals and/or the base station (NB1);

the at least two terminals each having at least one control facility controlling a transmission of data packets in the assigned resources by a transmitting/receiving facility; and

the at least one base station having at least one transmitting/receiving facility receiving data packets of the at least two terminals and transmitting confirmations of the receipt and a control facility controlling a transmission of the confirmations without an overlap in time, in an identical resource.
