Disclosed is a method for synchronizing transmission of signals from antenna reference points, ARP, () of a wireless communication network (). The method comprises initiating transmission of a first synchronization reference signal from a first ARP () at a first time point, instructing a second ARP () to determine a second time point for reception of the first synchronization reference signal, initiating transmission of a second synchronization reference signal from the second ARP () at a third time point, and instructing the first ARP to determine a fourth time point for reception of the second synchronization reference signal. The first and the second synchronization references signals are either transmitted in uplink communication resources available or they are transmitted in downlink communication resources. The method further comprises initiating transmission of data from the first ARP () to wireless devices () at a time point determined based on the first, second, third and fourth time points.
