Abstract:
1. A method for generating a power control command in a transceiver in a wireless communication system, the method comprising calculating, at the beginning of a predefined time period, a quality measure reference value; generating, repeatedly during the predefined time period, an estimated quality measure value of a signal received at the transceiver; calculating, at a given point in time during the predefined time period, an effective quality measure value from estimated quality measure values previously generated; generating, a number of times during the predefined time period, a modified quality measure reference value in dependence of a difference between the effective quality measure value and said quality measure reference value; generating a plurality of power control commands during the predefined time period by, for each of the modified quality measure reference values generated during the predefined time period, comparing the estimated quality measure value with the modified quality measure reference value; and resetting, at the beginning of a next predefined time period, the modified quality measure reference value to the quality measure reference value, wherein: the predefined time period is divided into a number of sub periods; and the method further comprises generating the modified quality measure reference value as a predetermined threshold value for a remaining time of the predefined time period, if a value of the modified quality measure reference value for a given next sub period becomes zero or negative.
