Samsung patents 5G method for devices to relay messages based on signal strength
Samsung has filed a patent application for a method that allows one mobile device to act as a relay for another in 5G or 6G networks. The system uses a specific signal strength threshold to decide whether the relay device should forward a discovery message from one user to another.
In the filing’s own words
The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system to support a data transmission rate higher than before. Disclosed is a method performed by a first user equipment (UE), including obtaining configuration information including information on a threshold used for identifying, by the first UE performing a UE-to-UE (U2U) relay operation, whether to perform transmission of a second message based on a first message received by the first UE from a second UE, receiving, from the second UE, a first discovery message including information on the second UE, identifying, based on reference signal received power (RSRP) measured based on communication with the second UE and the threshold, whether to perform transmission of the second message based on the received first discovery message, and performing, based on a result of the identification, transmission of the second message based on the received first discovery message.
What exactly they claim (claim 1)
1. A method performed by a relay user equipment (UE) for a sidelink UE-to-UE (U2U) relay in a wireless communication system, the method comprising: obtaining first configuration information for the relay UE including information on a first reference signal received power (RSRP) threshold for the relay UE; determining, based on the information on the first RSRP threshold, whether to forward a first discovery message received from a source remote UE; and transmitting, to a target remote UE, the first discovery message based on the determination, wherein the first discovery message includes a direct communication request (DCR) message.
