A method of multi-connectivity operation of a wireless device in Discontinuous Reception, DRX, comprising: determining whether a first DRX ON duration in a first DRX cycle configured for use by the wireless device in a first cell group for multi-connectivity operation and a second DRX ON duration in a second DRX cycle configured for use by the wireless device in a second cell group for multi-connectivity operation partially overlap in time with one another; and upon determining that the first DRX ON duration and the second DRX ON duration partially overlap in time with one another, taking one or more actions that mitigate the partial overlap between the first DRX ON duration in the first DRX cycle configured for use by the wireless device in the first cell group and the second DRX ON duration in the second DRX cycle configured for use by the wireless device, characterized in that taking the one or more actions comprises: deciding to use only non-successive DRX ON durations in at least one of the first cell group and the second cell group such that partially overlapping DRX ON durations between the first and second DRX cycles of the first and second cell groups are avoided; and changing between DRX states in at least one of the first DRX cycle and the second DRX cycle according to the decided use of only the non-successive DRX ON durations in the at least one of the first cell group and the second cell group. determining whether a first DRX ON duration in a first DRX cycle configured for use by the wireless device in a first cell group for multi-connectivity operation and a second DRX ON duration in a second DRX cycle configured for use by the wireless device in a second cell group for multi-connectivity operation partially overlap in time with one another; and upon determining that the first DRX ON duration and the second DRX ON duration partially overlap in time with one another, taking one or more actions that mitigate the partial overlap between the first DRX ON duration in the first DRX cycle configured for use by the wireless device in the first cell group and the second DRX ON duration in the second DRX cycle configured for use by the wireless device, characterized in that taking the one or more actions comprises: deciding to use only non-successive DRX ON durations in at least one of the first cell group and the second cell group such that partially overlapping DRX ON durations between the first and second DRX cycles of the first and second cell groups are avoided; and changing between DRX states in at least one of the first DRX cycle and the second DRX cycle according to the decided use of only the non-successive DRX ON durations in the at least one of the first cell group and the second cell group. deciding to use only non-successive DRX ON durations in at least one of the first cell group and the second cell group such that partially overlapping DRX ON durations between the first and second DRX cycles of the first and second cell groups are avoided; and changing between DRX states in at least one of the first DRX cycle and the second DRX cycle according to the decided use of only the non-successive DRX ON durations in the at least one of the first cell group and the second cell group.
