Resource allocation methods and nodes with self-adapting to different synchronizations

Abstract:

A method of operating a network node grants a first resource for UE transmissions and identified by a time identifier mapped to a first synchronization reference and by a frequency identifier. The time and frequency identifiers are identified by a relative resource identifier. A second resource is reserved for transmissions by the UE, and is identified by the time identifier mapped to a second synchronization reference and by the frequency identifier. The first and second synchronization references can be used by a UE for transmissions synchronization. The relative resource identifier is sent to the UE for use in controlling transmissions. Responsive to information reported by the UE indicating the UE is using the second synchronization reference for transmissions synchronization, a new relative resource identifier is sent that identifies a time identifier mapped to the second synchronization reference that corresponds to a location of the second resource and identifies the frequency.
