Method and device for user cooperative communication

摘要

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.

主权项

1. 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.
