A wireless network system and corresponding methodologies that operate in a user cooperative communication system are provided. In operation, the system either combines packets transmitted from a direct channel with packets transmitted from and a relay channel, or uses erroneously relayed packets to assist decoding a direct packet.

Method and device for user cooperative communication

Providing for soft error decoding for wireless relay networks is described herein. By way of example, a wireless node in a wireless relay network can receive a direct signal from a source node, and can receive a forwarded version of the source signal from a relay node. An information flag included with the forwarded version is referenced to determine whether the relay node properly received the source signal. If the relay node received the source signal with an error and a destination node received the source signal with an error, soft decision information can be generated from the forwarded version of the source signal and employed to assist with decoding of the source signal at the destination node. The soft-decision information improves end-to-end performance of the wireless relay system, while mitigating complexity and bandwidth requirements for the relay node as compared with conventional signal decoding techniques.

Soft forwarding for cooperative wireless communication

A wireless network system and corresponding methodologies that operates in a user cooperative communication system is provided. In operation, the system either combines packets transmitted from a direct channel with packets transmitted from and a relay channel, or uses erroneously relayed packets to assist decoding a direct packet.
