Abstract
A radio network node (110) manages (A010) establishment of a current radio session between a user equipment (120) and the radio network node (110), wherein the current radio session is associated with a current set of characteristics relating to the radio network node (110) and/or the user equipment (120). During establishment of the current radio session, a core network node (130) retrieves (A080), based on the current set of characteristics, an indication about the MCS offset from a memory (141, 142) accessible by the core network node (130). Then, the core network node (130) sends (A090), to the radio network node (110), the indication about the MCS offset. The indication is derived from a previous radio session, wherein the previous radio session is associated with a previous set of the characteristics, wherein the previous set of the characteristics matches the current set of the characteristics. The radio network node (120) determines (A130) a MCS based on the MCS offset and on a Channel Quality Indicator, “CQI”. Furthermore, the radio network node (110) transmits (A140) a data packet according to the MCS. Corresponding computer program sand carriers therefor are also disclos…
