According to embodiments herein a method, performed by a first base station (12), is provided for handling scheduling of Time Division Duplex, TDD, uplink and/or downlink subframes for a wireless terminal (10), which wireless terminal (10) is in dual connectivity with a first cell served by said first base station (12) and a second cell served by a second base station (13). The first base station 12: identifies a subframe in which an uplink/downlink scheduling conflict will occur between the first cell and the second cell due to a difference between a TDD configuration of the first cell and a TDD configuration of the second cell; determines a scheduling for the identified subframe based on at least one scheduling parameter; and sends, to the second base station (13), a scheduling instruction comprising the determined scheduling for the identified subframe.
