1. A method in a network node for reducing impact of interference in a cell from at least another neighbouring cell, the cell operating using a time division duplex (TDD) configuration, and the neighbouring cell operating using another TDD configuration, where the TDD configuration and the another TDD configuration are each divided into different time units for at least downlink (DL) and uplink (UL) transmissions, the method comprising:
assigning time units in the TDD configuration to one of at least two time unit groups, where assignment of a time unit to a time unit group is based on the another TDD configuration used in the neighbouring cell, where different HARQ processes are used for the at least two different time unit groups, and where the HARQ processes associated with the at least two different time unit groups are associated with different link adaptation outer loops; and
using different link adaptation methods for the at least two time unit groups.
