Method and device for resource group spatial relationships in wireless communication

A base station, comprising:

• a transmitter configured to transmit control information indicating a resource pool, wherein the resource pool includes a plurality of resource sets, and a sub-pool includes a portion of the plurality of resource sets, each resource set of the plurality of resource sets includes a plurality of resource groups, a resource group of the resource pool is part of one of a plurality of resource group subsets, a first resource set of the plurality of resource sets has a first index in the sub-pool, and a number of resource groups in each resource set of the plurality of resource sets is the same, a first resource group of the plurality of resource groups of the first resource set has a second index, and the first resource group belongs to a first resource group subset of the plurality of resource group subsets, and the first resource group subset is related to at least one of the first index or the second index, and the plurality of resource group subsets respectively correspond to a plurality of quasi-colocation spatial relations that indicate a respective plurality of reference signals,
• wherein the resource pool is monitored.
