Samsung patents method for phones to relay data for other devices

Samsung has been granted a patent for a method where one phone acts as a relay to send data from another device to a cell tower. The relay phone tells the tower it is helping a specific device, and the tower sends instructions on how to handle that data. This allows the second device to communicate through the first phone's connection.

Why it mattersThis could improve network coverage in areas with weak signal strength by allowing devices to share connections more efficiently.

In the filing’s own words

Provided is a method, performed by a relay user equipment (UE), of relaying communication between a remote UE and a base station, in a wireless communication system. The method includes: transmitting, to the base station, a message about sidelink UE information including first identifier information of the remote UE; receiving, from the base station, a radio resource control (RRC) reconfiguration message including configuration information for relaying data of the remote UE and second identifier information, based on the message about the sidelink UE information; and transmitting the data of the remote UE to the base station, based on the RRC reconfiguration message.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: transmitting, to a base station, a sidelink UE information message including information indicating that the UE is acting as a relay UE, information associated with an identifier (ID) for a remote UE and transmission (TX) resource request information for a sidelink communication; receiving, from the base station, a radio resource control (RRC) reconfiguration message associated with a relay operation, the RRC reconfiguration message including identification information of the remote UE used in a sidelink relay adaptation protocol (RAP); and performing the relay operation, based on the RRC reconfiguration message, wherein the RRC reconfiguration message further includes information indicating a list of one or more Uu relay radio link control (RLC) channel IDs corresponding to one or more Uu relay RLC channels to be added or modified, and information indicating a list of one or more Uu relay RLC channel IDs corresponding to one or more Uu relay RLC channels to be released.
