Patent ID: 7020483

Claim:
A method for transmission power control in a radio communications system having at least one mobile station and one base station which communicate with each other, the method comprising the steps of: determining, via the at least one mobile station, a reception power level of a signal which is sent from the at least one base station in a data channel during active communication; transmitting, via the transmitting one of the mobile stations, a power control instruction, wherein the power control instruction is derived from the determined reception power level; determining, via the at least one mobile station, a further reception power level signal that is sent from the at least one base station in a general signaling channel that is independent of the data channel, wherein the further reception power level is determined during an interruption in the active data communication in order to derive further transmission power control instruction, said further transmission power control instruction being derived from the further reception power level; sending, from the at least one mobile station, a plurality of further power control instructions to the at least one base station during the interruption in the active data communication; adding up, at the at least one base station, the received further power control instructions received from the at least one mobile station to form a sum as a power control instruction; and resuming the transmission, after the interruption in the active data transmission, via the base station, of signals in the data channel at a power level that is a sum of the transmission power before the interruption and the sum of power control instructions during the interruption.
