Abstract: A method of scheduling user equipment, a multiple antenna network node and computer program are disclosed. The method comprises: estimating at least one access network node channel within the unlicensed band between at least one access node operable to transmit in the unlicensed band, such as a WiFi Access Point, and the multiple antenna network node. Estimating a plurality of user equipment channels within the unlicensed band between a plurality of user equipment and the multiple antenna network node. Determining a degree of channel correlation of each of the plurality of user equipment channels and the at least one access node channel. Selecting at least one of the multiple user equipment to be scheduled, using the degree of channel correlation as a selection parameter, a lower degree of channel correlation increasing a user equipment's chance of being selected. In this manner the interference that LTE transmissions from and to scheduled UEs create on the at least one access node is reduced.
