Transmission power control

An apparatus comprising:

• at least one processor;
• and
• at least one memory including 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:
• determine a predetermined maximum transmission power reduction value for a user terminal;
• control transmission of the predetermined maximum transmission power reduction value to the user terminal;
• control transmission to the user terminal of an uplink resource allocation related to a given transmission resource.

A method comprising:

• determining a given transmission resource for transmission;
• determining a first transmission power level;
• determining prior to transmitting on the given transmission resource whether the resource is occupied or unoccupied;
• upon detecting that the resource is occupied,
• determining a second, reduced transmission power by applying a transmission power reduction such that a transmission using the second, reduced transmission power would not render the resource as occupied, wherein the determination of the second, reduced transmission power is based at least partially on a predetermined maximum transmission power reduction value;
• and
• transmitting utilising the given transmission resource using the second reduced transmission power according to the determination.
