Claim Text:
1. A method for wireless communication, comprising: receiving, at a relay, at least one assignment for a packet; determining, at the relay, assigned resources for the packet based on the at least one assignment; receiving, at the relay, at least one transmission of the packet sent from a transmitter to a receiver, wherein the at least one transmission of the packet is received on the assigned resources; processing, at the relay, the at least one transmission to decode the packet; determining, at the relay, whether the packet is decoded correctly after each transmission of the packet from the transmitter, the transmitter terminating transmission of the packet in response to receiving a first acknowledgement (ACK) from the relay; generating, at the relay, at least one additional transmission of the packet after correctly decoding the packet; sending, at the relay, the at least one additional transmission of the packet from the relay to the receiver when the relay receives a negative acknowledgement (NAK) from the receiver wherein the at least one additional transmission of the packet is sent on the assigned resources; detecting, at the relay, whether a second ACK or second NAK is received from the receiver after each additional transmission of the packet sent from the relay; and sending, from the relay, another additional transmission of the packet to the receiver when the second NAK is received, wherein the at least one additional transmission and the another additional transmission of the packet comprise a hybrid automatic repeat request (HARQ) transmission comprising different redundancy information for the packet.
