US Patent 11177871 Control signaling for the relay scenarios

An origination device (e.g., a base station) transmits a “received signal” to a signal forwarding device. The “received signal” comprises a first set of data, a first set of control information, and a second set of control information. The first and second sets of control information are both associated with the first set of data. The first set of control information contains instructions pertaining to the signal forwarding device processing the first set of data. The second set of control information contains instructions pertaining to a destination device (e.g. a user equipment (UE) device) processing the first set of data. The signal forwarding device transmits a “forwarded signal” to the destination device. The “forwarded signal” contains forwarded data, based on the first set of data, and forwarded control information, based on the second set of control information.
