Abstract

An origination device (e.g., a base station) combines and encodes first user data and second user data, having similar QoS requirements, to generate a multiuser packet. 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).

Dependent claims

A method comprising:

combining first data associated with a first user with second data associated with a second user;
encoding the first data and the second data, where the combined, encoded first data and second data is a multiuser packet, wherein encoding the first data and the second data comprises
encoding the first data, according to a first set of encoding parameters corresponding to channel conditions associated with a first communication link between a signal forwarding device and a first destination device associated with the first user, and
encoding the second data, according to a second set of encoding parameters corresponding to channel conditions associated with a second communication link between the signal forwarding device and a second destination device associated with the second user, and
wherein the combining, which occurs after encoding the first data and encoding the second data, yields a single-encoded data block;
encoding the single-encoded data block, according to a third set of encoding parameters corresponding to channel conditions associated with a third communication link between an origination device and the signal forwarding device, to generate a dual-encoded multiuser packet;
and
transmitting the multiuser packet to the signal forwarding device configured to decode the multiuser packet to obtain the first data and the second data.
