Abstract

Examples described herein include apparatuses and methods for full duplex device-to-device cooperative communication. Example systems described herein may include self-interference noise calculators. The output of a self-interference noise calculator may be used to compensate for the interference experienced due to signals transmitted by another antenna of the same wireless device or system. In implementing such a self-interference noise calculator, a selected wireless relaying device or wireless destination device may operate in a full-duplex mode, such that relayed messages may be transmitted as well as information from other sources or destinations during a common time period (e.g., symbol, slot, subframe, etc.).

Claims

1. A method, comprising:

transmitting, from a first set of antennas of a first device to a second device and a third device, a first message on a carrier during a first time period;

generating a self-interference noise signal at the first device based at least in part on the first message;

receiving, from the second device at a second set of antennas of the first device, a first part of a second message on the carrier during a first portion of the first time period, wherein the first part of the second message comprises a first part of a message from a fourth device and the first part of the second message is received based at least in part on the self-interference noise signal; and

receiving, from the third device at the second set of antennas of the first device, a second part of the second message on the carrier during a second portion of the first time period, wherein the second part of the second message comprises a second part of the message from the fourth device and is received based at least in part on the self-interference noise signal.

2. The method of claim 1, further comprising receiving a third message on the carrier during a second time period that is before the first time period, wherein the first message is transmitted in response to the third message.

3. The method of claim 2, wherein the first message comprises an acknowledgement (ACK) or a negative acknowledgment (NACK) for the third message.

4. The method of claim 1, wherein transmitting the first message comprises transmitting the first message on a sidelink to the second device.

5. The method of claim 1, wherein receiving second message comprises receiving the second message on a sidelink from the second device.

6. The method of claim 1, wherein the first device comprises first user equipment (UE), the second device comprises second UE, and the third device comprises third UE.

7. The method of claim 6, wherein the first UE, the second UE, and the third UE comprise a same category of UE.

8. The method of claim 6, wherein the fourth device comprises a third UE.

9. The method of claim 1, wherein the third device comprises a base station.

10. The method of claim 1, wherein the second device and the third device each comprise a respective relay node.
