Provided are a resource allocation method and device, a storage medium and an electronic device. The method includes the following operations. A first communication node determines resources needing to be allocated to a second communication node, where the resources include K clusters, each cluster includes one or more continuous resources, a maximum value of K is Kmax, Kmax is a predefined value or a value agreed in advance between the first communication node and the second communication node, and Kmax is a positive integer greater than 1. The first communication node notifies the second communication node of the resources, wherein the resources are resources needing to be avoided when the second communication node receives and/or sends a channel or a signal, or resources from which the second communication node, when needing to send data, selects one or more clusters of resources to send the data.
