Abstract

In a radio communications system, several codes for transmitting messages are assigned to a subscriber station. A transmission power differential is determined between the total maximum transmission power of the subscriber station for the codes and the total transmission power of the subscriber station for the codes at the beginning of a message transmission, (the differential being respected by the subscriber station), by a first one of the codes.

12. A method for operating a radio communication system in which a subscriber station is assigned a plurality of codes for transmitting messages, comprising:
- determining a transmit power difference which is to be maintained by the subscriber station between on one hand a total maximum transmit power of the subscriber station for the codes and on another hand a total transmit power of the subscriber station for the codes at a start of a message transmission using a first one of the codes.
- View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
- - 13. The method as claimed in claim 12,wherein said determining of the transmit power difference is performed by a network device, andwherein said method further comprises sending from a base station to the subscriber station a message containing information relating to the transmit power difference as determined by the network device.
  - 14. The method as claimed in claim 13, wherein the message to the subscriber station contains information relating to a maximum data rate to be used by the subscriber station for the message transmission using the first code.
  - 15. The method as claimed in claim 14, wherein said determining of the transmit power difference is based on a function of at least one of a property of the base station, a property of a radio cell of the base station, an interference situation, at least one service used by the subscriber station, and a classification of the subscriber station.
  - 16. The method as claimed in claim 13, wherein said determining of the transmit power difference is based on a function of at least one of a property of the base station, a property of a radio cell of the base station, an interference situation, at least one service used by the subscriber station, and a classification of the subscriber station.
  - 17. The method as claimed in claim 12, wherein said determining of the transmit power difference is performed by the subscriber station.
  - 18. The method as claimed in claim 17, wherein said determining of the transmit power difference is based on a function of a plurality of transmit powers used previously by the subscriber station for a second of the codes.
  - 19. The method as claimed in claim 18, wherein the radio communication system is a Universal Mobile Telecommunications System radio communication system.

20. A method for operating a radio communication system in which a subscriber station is assigned a plurality of codes for transmitting messages, comprising:
- maintaining a previously determined transmit power difference by the subscriber station between on one hand a total maximum transmit power of the subscriber station for the codes and on another hand a total transmit power of the subscriber station for the codes at a start of a message transmission using a first one of the codes.
- View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
- - 21. The method as claimed in claim 20, wherein the transmit power difference is determined on the network side and a base station sends the subscriber station a message containing information relating to the defined transmit power difference.
  - 22. The method as claimed in claim 21, wherein the message to the subscriber station contains information relating to a maximum data rate to be used by the subscriber station for the message transmission using the first code.
  - 23. The method as claimed in claim 22, wherein said determining of the transmit power difference is based on a function of at least one of a property of the base station, a property of a radio cell of the base station, an interference situation, at least one service used by the subscriber station, and a classification of the subscriber station.
  - 24. The method as claimed in claim 21, wherein said determining of the transmit power difference is based on a function of at least one of a property of the base station, a property of a radio cell of the base station, an interference situation, at least one service used by the subscriber station, and a classification of the subscriber station.
  - 25. The method as claimed in claim 20, wherein said determining of the transmit power difference is performed by the subscriber station.
  - 26. The method as claimed in claim 25, wherein said determining of the transmit power difference is based on a function of a plurality of transmit powers used previously by the subscriber station for a second of the plurality of codes.
  - 27. The method as claimed in claim 26, wherein the radio communication system is a Universal Mobile Telecommunications System radio communication system.

28. A base station in a radio communication system in which a subscriber station is assigned a plurality of codes for transmitting messages, comprising:
- means for determining a transmit power difference which is to be maintained by the subscriber station between on one hand a total maximum transmit power of the subscriber station for the codes and on another hand a total transmit power of the subscriber station for the codes at a start of a message transmission using a first one of the codes.

29. A subscriber station for a radio communication system, the subscriber station assigned a plurality of codes for transmitting messages, comprising:
- means for determining a transmit power difference which is to be maintained by the subscriber station between on one hand a total maximum transmit power of the subscriber station for the codes and on another hand a total transmit power of the subscriber station for the codes at a start of a message transmission using a first one of the codes.
- View Dependent Claims (30)
- - 30. A subscriber station as claimed in claim 29, further comprising means for maintaining the transmit power difference.
