Abstract
The invention discloses a data transmission method and device and solves problems that the system frequency spectrum utilization rate is low as the conventional distributed algorithm based on time slot reservation occupies time frequency resources. The method comprises steps that a first node selects the first time-frequency resource occupied by the first node from the time-frequency resource corresponding to a sub-band in which the first node is idle, from 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 expect the time frequency resource occupied by the first node on the time slot capable of frequency division multiplexing is a second time frequency resource occupied by a second node, and space isolation between the first node and all the second nodes on the time slot capable of frequency division multiplexing is smaller than or equal to the maximal distance required among nodes with communication requirements. Therefore, frequency division multiplexing of different time frequency resources of the same time slot is achieved for at least two nodes with communication requirements, the system frequency spectrum utilization rate is improved, and the system capacity is improved.
