METHOD AND DEVICE FOR CONTROLLING A TRANSMIT POWER IN A RADIO COMMUNICATIONS SYSTEM
First Claim
1. A method for controlling a transmit power in a radio communications system, comprising:
- receiving a request to increase a transmit power of an uplink channel at a communication device;
determining whether the transmit power was at a maximum upon receipt of a previous request to increase the transmit power preceding the received request at the communication device;
increasing the transmit power by a first step size at the communication device if the transmit power was not at the maximum upon receipt of the previous request; and
increasing the transmit power by a second step size greater than the first step size at the communication device if the transmit power was at the maximum upon receipt of the previous request.

Abstract
A method for controlling a transmit power in a radio communications system includes receiving a request to increase a transmit power of an uplink channel and determining whether the transmit power was at a maximum upon receipt of a previous request to increase the transmit power preceding the received request. If the transmit power was not at the maximum upon receipt of the previous request, the transmit power is increased by a first step size and if the transmit power was at the maximum upon receipt of the previous request, the transmit power is increased by a second step size greater than the first step size.

18. A method for controlling a transmit power in a radio communications system, comprising:
-
receiving a request to increase a transmit power of an uplink channel at a communication device; determining whether the transmit power was at a maximum upon receipt of a previous request to increase the transmit power preceding the received request at the communication device; and increasing the transmit power during a time duration of smaller than two time slots to the latest preceding value of the transmit power that was not at the maximum at the communication device if the transmit power was at the maximum upon receipt of the previous request.

19. A method for controlling a transmit power in a radio communications system, comprising:
-
receiving a request to increase a transmit power of an uplink channel at a communication device; determining a value of a degradation of the transmit power at the communication device; determining whether the transmit power was at a maximum upon receipt of a previous request to increase the transmit power preceding the received request at the communication device; and increasing the transmit power during a time duration of smaller than two time slots to the larger one of the degradation value and a predetermined minimum step size at the communication device if the transmit power was at the maximum upon receipt of the previous request.

20. A device for controlling a transmit power in a radio communications system, comprising:
-
a first unit configured to receive a request to increase a transmit power of an uplink channel; a second unit configured to determine whether the transmit power was at a maximum upon receipt of a previous request to increase the transmit power preceding the received request; and a third unit configured to; increase the transmit power by a first step size if the transmit power was not at a maximum upon receipt of the previous request; and increase the transmit power by a second step size greater than the first step size if the transmit power was at the maximum upon receipt of the previous request.
