Abstract
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.
Claims20
A method, comprising:
- receiving, by a system including at least one processor, a first packet via a direct channel;
- receiving a second packet via a relay channel;
- receiving an indication in the second packet indicating that an interlink packet passed or failed a first packet error detection;
- and in response to the first packet failing to pass a second packet error detection, the second packet indicating that the interlink packet failed to pass the first packet error detection and the second packet passing the second packet error detection, decoding the first packet using a log-likelihood ratio (LLR) comprising side information relating to the second packet.

A system, comprising:
- a memory;
- and at least one processor, communicatively coupled to the memory, that executes or facilitates execution of one or more system-executable components, including:
- a receiving module configured to receive a first packet via a direct channel, a second packet via a relay channel, and an indication in the second packet that an interlink packet passed or failed a first packet error detection;
- an error detection module configured to perform a second packet error detection on the first packet and the second packet;
- and a decoder configured to decode the first packet using a log-likelihood ratio (LLR) comprising side information relating to the second packet in response to the first packet failing to pass the second packet error detection and the second packet passing the second packet error detection.

A computer-readable storage medium having computer-executable instructions stored thereon that, in response to execution, cause a system including at least one processor to perform operations, comprising:
- receiving a direct packet via a direct channel and a relay packet via a relay channel;
- detecting an indication in the relay packet that an interlink packet passed or failed a first interlink packet error detection;
- performing a second packet error detection on the direct packet and the relay packet;
- and in response to the direct packet failing to pass the second packet error detection, the the relay packet indicating that the interlink packet failed to pass the first packet error detection, and the relay packet passing the second packet error detection, decoding the direct packet using a log-likelihood ratio (LLR) comprising side information relating to the relay packet.
