Embodiments herein relate to a method performed by a network node (110), for handling baseband resources in a wireless communications network (100). The network node (110) estimates an uplink resource need f( . . . ) and a downlink resource need g( . . . ) for a future Transmission Time Interval i based on resource metrics from one or more previous Transmission Time Intervals. The network node (110) determines a resource division between uplink and downlink based on the estimated uplink and downlink resource needs. The network node (110) further schedules the uplink and downlink resources based on the determined resource division.
