Method for resource allocation in a wireless communication network, method for error-free transmission of information, node and wireless communication network

A method for transmission of information between a sender and a receiver over a wireless communication network, the wireless communication network further comprising a relay station, the method comprising:

• transmitting a codeword from the sender to the receiver,
• in case the codeword is falsely decoded at the receiver, requesting a retransmission of information from the relay station,
• allocating a resource for retransmission by the relay station in accordance with a method for resource allocation in the wireless communication network including the sender, the relay station and the receiver,
• wherein the receiver is configured to receive, combine and decode signals received from the sender and the relay station,
• wherein in case the receiver fails to decode a received signal, a retransmission of information from the relay station to the receiver is initiated, and
• wherein allocation of the resource for retransmission by the relay station is determined based on a relay protocol upon which the relay station operates, a channel quality of a channel between the sender and the receiver via the relay station, and a channel quality of a direct channel between the sender and the receiver, and
• performing the retransmission using the allocated resource from the relay station to the receiver to enable the receiver to decode the codeword, after the retransmission, with a predefined probability.

A non-transitory computer-readable medium comprising a program comprising instructions executable by a computer, the computer-readable medium comprising:

• instructions to execute a method for resource allocation in a wireless communication network including a sender, a relay station and a receiver,
• wherein the receiver receives, combines and decodes signals from the sender and the relay station, and
• instructions to initiate retransmission of information from the relay station to the receiver in a case where the receiver fails to decode a received signal;
• and
• instructions to determine a resource for retransmission of information from the relay station to the receiver based on a relay protocol upon which the relay station operates, a channel quality of a channel between the sender and the receiver via the relay station, and a channel quality of a direct channel between the sender and the receiver.

A node in a wireless communication network, the wireless communication network comprising a sender, a relay station and a receiver, the node comprising:

• a processor configured to allocate a resource in case of a retransmission from the relay station to the receiver in accordance with a method for resource allocation in the wireless communication network including the sender, the relay station and the receiver,
• wherein the receiver is configured to receive, combine and decode signals from the sender and the relay station,
• wherein in a case where the receiver fails to decode a received signal, a retransmission of information from the relay station to the receiver is initiated, and
• wherein a resource necessary for retransmission is determined based on a relay protocol upon which the relay station operates, a channel quality of a channel between the sender and the receiver via the relay station, and a channel quality of a direct channel between the sender and the receiver.

A wireless communication network, comprising:

• a sender;
• a receiver configured to receive a codeword from the sender and to request a retransmission in case the codeword is falsely decoded;
• and
• a relay station configured to cause a retransmission of information in case the receiver falsely decoded the codeword,
• wherein at least one of the sender, the receiver and the relay station is configured as a node in the wireless communication network comprising the sender, the relay station and the receiver, the node comprising:
• a processor configured to allocate a resource in case of a retransmission from the relay station to the receiver in accordance with a method for resource allocation in a wireless communication network including a sender, a relay station and a receiver,
• wherein the receiver is configured to receive, combine and decode signals received from the sender and the relay station,
• wherein in case the receiver fails to decode a received signal, a retransmission of information from the relay station to the receiver is initiated, and
• wherein a resource necessary for retransmission is determined based on a relay protocol upon which the relay station operates, a channel quality of a channel between the sender and the receiver via the relay station, and a direct channel between the sender and the receiver.
