The present invention provides a method and device for feeding back grouping indication information and a method and device for acquiring grouping indication information. The method for feeding back grouping indication information includes: determining M resources from a candidate resource set and dividing the M resources into N first-type resource groups, where M is an integer greater than or equal to 1 and N is a positive integer less than or equal to M; and feeding back indication information for indicating the M resources and first-type grouping indication information for indicating that the M resources are divided into the N first-type resource groups to a first communication node. Resources in the candidate resource set include at least one of: a transmission beam resource, a transmission antenna resource, a transmission port resource, a transmission frequency domain resource, a transmission sequence resource and a transmission time domain resource.
