Method and device for resource group spatial relationships in wireless communication
The present disclosure provides a method and a device in a node for wireless communications. A first node receives a first information block; and monitors a first-type signaling in a first resource pool. The first information block is used for determining the first resource pool, the first resource pool comprises K resource sets, any resource set comprises a positive integer number of resource group(s); a first resource set is one of the K resource sets, a first index is an index of the first resource set in a first resource sub-pool, a number of resource groups comprised in the first resource set is equal to L0, and a number of resource groups comprised in any resource set in the first resource sub-pool is equal to L0. The above method improves reliability of physical layer control channel transmission.
