The invention relates to a method of synchronizing clocks of at least two devices in a network and a corresponding wireless device for synchronizing its clock with another wireless device. The method comprises steps of: transmitting a synchronization signal to said at least one second device to determine at least one time offset between a clock of the first device and at least one clock associated with said at least one second device; receiving said at least one time offset from said at least one second device; determining a time interval for the first device based on a time offset parameter corresponding to said at least one time offset, after which time interval the first device transmits a next synchronization signal to said at least one second device. With this method, the radio station is able to reduce its power consumption when the time offset between the first device and the second device is small.

A method in a radio network node for ranking cells within a group of cells in a cellular network is provided. The radio network node is serving a first cell, in the group of cells. The radio network node receives () power level measurements from one or more user equipments. The power level measurements respectively indicate a power level in at least one cell of the group of cells where the respective one or more user equipments is active. The radio network node then ranks () importance of the cells in the group of cells, both based on the power level measurements, and on the number, for each cell out of the group of cells, of user equipments whose power level measurements indicate that the respective cell has the highest power level.
