Description

Slot allocation method and electronic apparatus therefor The technical concept of the present disclosure relates to a slot allocation method and an electronic device for the same, and more specifically, to a method for allocating slots to a communication link established between a manned aircraft and an unmanned aircraft and an electronic device for performing the same. In environments where manned and unmanned aircraft form formations to perform cooperative missions, it may be required to reliably exchange control information and mission data through multiple communication links established between the aircraft. In particular, as the formation size increases and high-speed mobility grows, there is a greater tendency for multiple communication links to simultaneously transmit data within the same slot corresponding to the same time interval, which may increase the likelihood of collisions and retransmissions caused by interference. Conventionally, a method of distributing time slots to each node based on time division multiple access was considered. However, in environments where the traffic demand of nodes and the interference relationship between links change over time, relying solely on fixed or simple rule-based distribution can lead to under- or over-allocation of slots, resulting in transmission delays and reduced reliability. Additionally, a simple re-propagation method of state information between nodes can cause unnecessary retransmission of the same information, thereby increasing the waste of slot resources. Accordingly, regarding multiple communication links established between manned and unmanned aircraft, a slot allocation method and an electronic device for performing the same may be required, which can mitigate collisions and improve the stability and reliability of data transmission by selecting links capable of simultaneous transmission in the same slot and allocating the slot according to the selection result.
