CUAV coordination refers to utilizing the coordination of multiple CUAVs to accomplish specific tasks through network communication. To enable CUAVs to cooperate well and accomplish tasks successfully, three important parts need to be fulfilled. First, stable and reliable network connection is required to be established among CUAVs to ensure that every CUAV can connect with each other; second, efficient and reliable data transmission among CUAVs is required so as to ensure the perception information, control information, coordination information and other required information exchanged among CUAVs; finally, CUAV collaborative task execution strategy is required to be worked out reasonably during the coordination process in order to improve the efficiency and quality of collaborative task execution. This Recommendation specifies the requirements of CUAV coordination, including the requirements of network connection among CUAVs, the requirements of data transmission among CUAVs, and the requirements of CUAV collaborative task execution.
