1. A communication method of a receiver corresponding to a second transmitter, the method comprising:
- receiving a 1-1-(i−
1)th sub-message and a 2-1-(i−
1)th sub-message from among the 1-1-(i−
1)th sub-message, the 2-1-(i−
1)th sub-message, a 2-1- (i)th sub-message, and a 3-1-(i−
1)th sub-message transmitted from a first transmitter based on different transmission powers in a (i−
1)th time slot;
receiving a 1-2-(i−
1)th sub-message, a 2-2-(i−
1)th sub-message, a 2-2-(i)th sub-message, and a 3-2-(i−
1)th sub-message transmitted from the second transmitter based on different transmission powers in the (i−
1)th time slot;
decoding the 1-2-(i−
1)th sub-message and the 2-2-(i−
1)th sub-message;
eliminating the 1-2-(i−
1)th sub-message and the 2-2-(i−
1)th sub-message from the received sub-messages; and
providing, to a receiver corresponding to the first transmitter, the 1-1-(i−
1)th sub-message, the 2-1-(i−
1)th sub-message, the 2-2-(i)th sub-message and the 3-2-(i−
1)th sub-message.

Abstract
Each of a first transmitter and a second transmitter uses a rate split scheme. Each of the first transmitter and the second transmitter may transmit at least four sub-messages, and different transmission powers may be allocated to the at least four sub-messages. Also, each of receivers may cooperate with each other, may share sub-messages that act as interferences, and may extract desired messages using the shared sub-messages.

5. A communication method of a receiver corresponding to a first transmitter, the method comprising:
-
distinguishing a 1-1-(i−
1)th sub-message, a 2-1-(i−
