Method and apparatus of a source network device and a destination network device for autonomous transmission are provided in this disclosure. In a source network device, a coordination indicator and a portion of data is transmitted to the destination network device, the coordination indicator identifying a resource coordination zone to coordinate interference resolution. Then, the source network device determines whether an acknowledgement is received from the destination device prior to an allocation of its repeated transmission. When a message is detected in the resource coordination zone and the acknowledgement is received, the source device transmits a further portion of the data to be transmitted. Problem arising from channel interference can be resolved through the provided methods.
