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.

Methods, systems and antenna reference points of a wireless communication network for synchronizing transmission of signals

A method performed by a system of a wireless communication network is disclosed. The method relates to provisioning of a time-sensitive service related to a wireless device. The wireless communication network comprises a plurality of antenna reference points, ARPs, of one or more radio access network nodes of the wireless communication network. The method comprises obtaining information that a first ARP and a second ARP of the plurality of ARPs are to provide the time-sensitive service to the wireless device, determining, by inter-ARP radio signalling between ARPs of one or more pairs of the plurality of ARPs, one of the one or more pairs including the first ARP and one of the one or more pairs including the second ARP, a relative timing error between the first ARP and the second ARP, and taking the determined relative timing error into consideration when providing the service to the wireless device.
