Patent ID: 8611943

Claim:
A method of controlling updating of a signal quality target for power control of an ongoing radio transmission in a radio communication system (SYS 1 ), wherein said signal quality target is updated based on communication quality so that the signal quality target is increased when encountering events indicating that the communication quality is below a communication quality target and the signal quality target is reduced when encountering events indicating that the perceived communication quality is above the communication quality target, said method comprising: detecting a change in transmission format from a first transmission format to a second transmission format for the radio transmission; and blocking, for a predefined blocking period after detecting said change in transmission format, any updates causing the signal quality target to increase due to communication quality being below the communication quality target, wherein said blocking step is selectively applied when at least one of the following conditions are fulfilled: the first transmission format has been used at least for a predefined period of time; the first transmission format has been used in at least a predefined percentage of time in a predefined period of time; and the number of instances where said blocking step has been applied during a predefined period of time is less than a predefined number.
