In some cases, the origination device dual-encodes the multiuser packet. The multiuser packet is transmitted to one or more signal forwarding devices that each serve at least one of the users associated with the data contained in the multiuser packet. The signal forwarding device decodes the multiuser packet to obtain the first and second user data. The signal forwarding device transmits at least one portion of the multiuser packet, as single-encoded signals, to one or more appropriate destination devices (e.g., UE devices). ## Claims ### Claim 1 A method comprising: combining first data associated with a first user with second data associated with a second user;
