Apparatuses and methods for transmission power control are disclosed. A given transmission resource and a first transmission power are determined (202, 204) for transmission. Prior to transmitting on the given transmission resource it is determined (206) whether the resource is occupied or unoccupied. Upon detecting that the resource is occupied, a second, reduced transmission power is determined (210) such that a transmission using the second, reduced transmission power would not render the resource as occupied. The determination of the second transmission power is based at least partially on a predetermined maximum transmission power reduction value. Transmission (212) is done utilising the given transmission resource using the second transmission power according to the determination.

A method and a network node (300) for enabling wireless communication with a wireless device (302), wherein no more than a pre-determined maximum total transmit power is available for downlink transmission by the network node (300). When detecting that the wireless device (302) requires an extended transmission range (300B) which is larger than a nominal transmission range (300A), a boosted transmit power is determined and used for transmitting a first set of channels and/or signals to be used by the wireless device (302) to achieve the extended transmission range (300B). An attenuated transmit power is also determined and used for transmitting a second set of channels and/or signals not included in the first set of channels and/or signals, which provides a slightly reduced transmission range (300C) for the second set. The boosted transmit power is thus higher than a nominal transmit power, and the attenuated transmit power is lower than the nominal transmit power, so that the total transmit power used for transmitting said first and second sets does not exceed the pre-determined maximum total transmit power.
