A method of adjusting an estimated signal quality in an outer-loop link adaptation, LA, process, comprising: receiving a channel stale information, CSI, report from a user equipment; estimating a signal quality based on the CSI report and an outer-loop adjustment; selecting a modulation and coding scheme, MCS, for transmission of a data packet based on the estimated signal quality and a target error rate, wherein the selected MCS may be normal, conservative or aggressive, wherein the selected MCS is normal, if it is a highest MCS with which the target error rate can be achieved under a current channel condition, wherein the selected MCS is conservative, if it is lower than the highest MCS, and wherein the selected MCS is aggressive, if it is higher than the highest MCS supported by the radio link; monitoring an outcome of the transmission; said method further characterized by: if the transmission has failed and the selected MCS is normal or conservative, reducing (708, 810) the outer-loop adjustment by a downward step; if the transmission has failed and the selected MCS is aggressive, reducing (720, 820) the outer-loop adjustment by the downward step when an accumulated aggressive adjustment is larger than a threshold; if the transmission is successful and the selected MCS is normal or aggressive, increasing (608, 830) the outer-loop adjustment by an upward step; and if the transmission is successful and the selected MCS is conservative, increasing (620, 840) the outer-loop adjustment by the upward step when an accumulated conservative adjustment is smaller than a threshold; wherein the accumulated conservative adjustment is reduced by the downward step when the transmission is failed and the selected MCS is conservative and wherein the accumulated conservative adjustment is increased (612, 620) by the upward step when the transmission is successful and the accumulated conservative adjustment is smaller than a threshold; and wherein the accumulated aggressive adjustment is increased by the upward step when the transmission is successful and the selected MCS is aggressive and wherein the accumulated aggressive adjustment is reduced (712, 720) by the downward step when the transmission has failed and the accumulated aggressive adjustment is larger than a threshold. receiving a channel stale information, CSI, report from a user equipment; estimating a signal quality based on the CSI report and an outer-loop adjustment; selecting a modulation and coding scheme, MCS, for transmission of a data packet based on the estimated signal quality and a target error rate, wherein the selected MCS may be normal, conservative or aggressive, wherein the selected MCS is normal, if it is a highest MCS with which the target error rate can be achieved under a current channel condition, wherein the selected MCS is conservative, if it is lower than the highest MCS, and wherein the selected MCS is aggressive, if it is higher than the highest MCS supported by the radio link; monitoring an outcome of the transmission; if the transmission has failed and the selected MCS is normal or conservative, reducing (708, 810) the outer-loop adjustment by a downward step; if the transmission has failed and the selected MCS is aggressive, reducing (720, 820) the outer-loop adjustment by the downward step when an accumulated aggressive adjustment is larger than a threshold; if the transmission is successful and the selected MCS is normal or aggressive, increasing (608, 830) the outer-loop adjustment by an upward step; and if the transmission is successful and the selected MCS is conservative, increasing (620, 840) the outer-loop adjustment by the upward step when an accumulated conservative adjustment is smaller than a threshold; wherein the accumulated conservative adjustment is reduced by the downward step when the transmission is failed and the selected MCS is conservative and wherein the accumulated conservative adjustment is increased (612, 620) by the upward step when the transmission is successful and the accumulated conservative adjustment is smaller than a threshold; and wherein the accumulated aggressive adjustment is increased by the upward step when the transmission is successful and the selected MCS is aggressive and wherein the accumulated aggressive adjustment is reduced (712, 720) by the downward step when the transmission has failed and the accumulated aggressive adjustment is larger than a threshold.
