The embodiments herein relates to a method in a first base station (201a) for controlling interference on a second Physical Downlink Control CHannel, PDCCH (210b). The second PDCCH (210b) is between a second base station (201b) and a second user equipment (205b). The first base station (201a) receives (602), from the second base station (201b), coordination information associated with the second PDCCH (210b). Based on the received coordination information, the first base station (201a) controls (306, 405, 503, 505, 507, 603) the interference on the second PDCCH (210b), wherein the interference is caused by a first PDCCH (210a) from the first base station (201a) to a first user equipment (205a). |
