Abstract
The present disclosure relates to delay compensation during synchronization of uplink and downlink frames in a base station in a cellular communication network. In general, the base station includes a radio equipment and a radio equipment controller that together form at least part of the base station. In one embodiment, the radio equipment includes a first interface configured to receive data from the radio equipment controller and a second interface configured to send data to the radio equipment controller. During synchronization, the radio equipment receives, at the first interface of the radio equipment, a synchronization message from the radio equipment controller. The radio equipment then passes the synchronization message from the first interface of the radio equipment to the second interface of the radio equipment with a synthetic delay that is in addition to an in-equipment delay from the first interface to the second interface.
