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.
Claims8
A communication method of a transmitter, the method comprising:
- generating a transmission message comprising:
- a 1-1-(i−1)th sub-message;
- a 2-1-(i−1)th sub-message;
- a 2-1-(i)th sub-message;
- and
- a 3-1-(i−1)th sub-message in a (i−1)th time slot;
- allocating transmission powers A, B, C, and D [W], respectively, in the transmission message of the (i−1)th time slot, A, B, C, and D denoting real numbers and A>B>C>D, to:
- the 1-1-(i−1)th sub-message;
- the 2-1-(i−1)th sub-message;
- the 2-1-(i)th sub-message;
- and
- the 3-1-(i−1)th sub-message;
- and
- generating a transmission message comprising the 2-1-(i)th sub-message in a (i)th time slot.
