Abstract
An operation method of a relay node in a wireless network using a superposition coding scheme is provided. In particular, a relay node may receive a first transmission message from a first source node in a first time slot. The relay node may also receive a second transmission message from a second source node in a second time slot. The relay node may then transmit a relay message to a first destination node corresponding to the first source node and a second destination node corresponding to the second source node in a third time slot, the relay message being associated with the first transmission message and the second transmission message.

An operation method of a relay node, the operation method comprising:
- receiving a first transmission message from a first source node in a first time slot, the first transmission message comprising a superposition-coding of a 1-1 partial source message and a 1-2 partial source message that are included in a first source message corresponding to the first source node;
- receiving a second transmission message from a second source node in a second time slot, the second transmission message comprising a superposition-coding of a 2-1 partial source message and a 2-2 partial source message that are included in a second source message corresponding to the second source node;
- and
- transmitting a relay message to a first destination node corresponding to the first source node and to a second destination node corresponding to the second source node, in a third time slot, the relay message comprising a superposition-encoding of the 1-1, 1-2, 2-1, and 2-2 partial source messages,
- wherein the first source node, the second source node, the first destination node and the second destination node are different from each other.
An operation method of a relay node, the operation method comprising:
- receiving, in a first time period, a first transmission message from a first source node, and a second transmission message from a second source node, the first transmission message comprising a superposition-coding of a 1-1 partial source message and a 1-2 partial source message that are included in a first source message corresponding to the first source node, and the second transmission message comprising a superposition-coding of a 2-1 partial source message and a 2-2 partial source message that are included in a second source message corresponding to the second source node;
- distinguishing the first transmission message from the second transmission message based on a Successive Interference Cancellation (SIC) scheme;
- and
- transmitting a relay message to a first destination node corresponding to the first source node and to a second destination node corresponding to the second source node, in a second time period, the relay message comprising a superposition-coding of the 1-1, 1-2, 2-1, and 2-2 partial source messages,
- wherein the first source node, the second source node, the first destination node and the second destination node are different from each other.
A computer-readable storage medium storing a program to provide an operation method of a relay node, comprising instructions to cause a computer to:
- receive a first transmission message from a first source node in a first time period, the first transmission message comprising a superposition-coding of a 1-1 partial source message and a 1-2 partial source message that are included in a first source message corresponding to the first source node;
- receive a second transmission message from a second source node in a second time period, the second transmission message comprising a superposition-coding of a 2-1 partial source message and a 2-2 partial source message that are included in a second source message corresponding to the second source node;
- and
- transmit a relay message to a first destination node corresponding to the first source node and to a second destination node corresponding to the second source node, in a third time period, the relay message comprising a superposition-coding of the 1-1, 1-2, 2-1, and 2-2 partial source messages,
- wherein the first source node, the second source node, the first destination node and the second destination node are different from each other.
