    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments of the present application provide a method and a device for routing a data packet, and a method and a device for controlling a data packet transmission. The data packet routing method includes: receiving a first message transmitted by a first node; and determining a transmission path of the data packet according to the first message. The method provided in the present application achieves that a node in a relay network can determine a condition for transmitting the data packet by using other transmission paths, thereby effectively using multiple transmission paths to implement the data packet transmission.
