Power control

An apparatus comprising:

• at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least 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 a location of the user terminal proportionate to 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.
