Systems and methods are disclosed herein that relate to Multi-User Multiple Input Multiple Output (MU-MIMO) aware sector-carrier allocation. In some embodiments, a method of operation of a network node in a wireless communication system comprises selecting a sector-carrier for a wireless device from among a plurality of sector-carriers in accordance with a MU-MIMO aware sector-carrier allocation procedure that takes into account possible MU-MIMO pairings for the wireless device on the plurality of sector-carriers. The method further comprises providing an indication of the sector-carrier selected for the wireless device to at least one node selected from a group consisting of: another network node and the wireless device. By taking into account possible MU-MIMO pairings for the wireless device when performing sector-carrier allocation, performance of the wireless communication system is improved.
