Abstract: According to an example aspect, there is provided an apparatus, configured to receive, by a user terminal, configuration for a grant-free transmission on a shared radio resource, the grant-free transmission comprising at least one collision avoidance transmission and at least one data transmission, wherein the at least one collision avoidance transmission precedes the at least one data transmission, determine a first transmission power for the at least one data transmission, determine a second transmission power for the at least one collision avoidance transmission based on information indicative to the a location of the user terminal proportionate to the a location of an access node providing a radio cell, and transmit the at least one collision avoidance transmission at the second determined power and the at least one data transmission at the determined first transmission power.

Abstract: Systems, methods, apparatuses, and computer program products for optimizing user equipment (UE) oriented link adaptation. One method may include receiving a configuration of a predefined transmission power for one or more cases. The method may also include calculating a required transmission power based on at least a specific pathloss of the one or more cases. In addition, the method may include, selecting, based on the calculation of the required transmission power, a modulation coding scheme level that does not exceed the predefined transmission power for a radio transmission. Further, the method may include performing the radio transmission based on the selected modulation coding scheme level and the calculated required transmission power.
