Abstract
The embodiments of the present invention disclose a data transmission method and device, which are used to solve the problem of low system spectrum utilization rate in the existing distributed algorithm based on time slot reservation and occupying time-frequency resources. The data transmission method includes: the first node selecting the first time-frequency resource occupied by the first node from the time-frequency resources corresponding to the sub-band that is free for the first node on the time slot capable of frequency division multiplexing, and Data transmission is performed on the first time-frequency resource, wherein at least one time-frequency resource other than the time-frequency resource occupied by the first node on the time slot capable of frequency division multiplexing is the second time occupied by the second node Frequency resources, the spatial isolation between the first node and all second nodes on the time slot capable of frequency division multiplexing is less than or equal to the maximum distance to be satisfied between nodes with communication requirements. The embodiment of the present invention realizes frequency division multiplexing between at least two nodes with communication requirements and different time-frequency resources in the same time slot, which improves the system spectrum utilization rate and also increases the system capacity.
