A method performed by a network node (110) for determining amounts of downlink transmission power for a downlink shared channel to be used in a Transmission Time Interval, TTI, by cells (201, 202) served by the network node (110) in a wireless telecommunications network (100) is provided. The network node determines downlink transmission power available to the cells (201, 202) for physical channels associated with the downlink shared channel based on the downlink transmission power allocated in the cells (201, 202) to physical channels associated with other downlink channels. Further, the network node determines an additional amount of downlink transmission power available to at least one first cell (201) based on the difference between the determined downlink transmission power available to at least one second cell (202) and a downlink transmission power that is required for the amount of data that is to be transmitted in the at least one second cell (202). A network node (110) for determining amounts of downlink transmission power for a downlink shared channel to be used in a Transmission Time Interval, TTI, by cells (201, 202) served by the network node (110) in a wireless telecommunications network (100) is also provided. |
