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.
