Full duplex device-to-device cooperative communication
First Claim
1. A method, comprising:
- approaching a plurality of devices via a vehicle;
transmitting, from a transceiver of the vehicle, a first message to a base station via the plurality of devices via a first set of antennas of the vehicle on a carrier during a first time period; and
contemporaneously receiving, at the transceiver, respective codes corresponding to a second message via respective signals transmitted from at least two of the plurality of devices, wherein the respective codes are generated using a particular data vector based on distributed space-time coding (DSTC), wherein the second message is provided to the plurality of device by the base station; and
reconstructing a second message from the signals by combining the respective signals with a self-interference noise signal generated based on the first message.

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.).

4. A system comprising:
-
a stationary communications device; a plurality of devices in communication with the stationary communications device; and a vehicle configured to move past the plurality of devices, wherein the vehicle is configured to communicate with the stationary communications device via the plurality of devices, wherein the vehicle is configured to transmit a first message to the stationary communications device via the plurality of devices via a first set of antennas on a carrier of a radio frequency bandwidth during a first time period and to receive a second message from the stationary communications device via at least two of the plurality of devices via a second set of antennas on the carrier of the radio frequency during the first time period, wherein the vehicle is configured to contemporaneously receive respective portions of the second message from the two or more of the plurality of devices via distributed space-time coding (DSTC), wherein, in DSTC, each of the two or more of the plurality of devices is configured to transmit respective codes generated using a particular data vector, wherein, to receive the second message, the vehicle is configured to generate an interference signal to filter the first message from signals received at the second set of antennas. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. A vehicle comprising:
a transceiver configured to transmit a first message on a carrier to a plurality of devices via a first set of antennas during a first time period and to receive a second message on the carrier from at least one of the plurality of devices via a second set of antennas, wherein the transceiver is further configured to generate a self-interference noise signal based on the first message and combine the self-interference noise signal with signals received from the second set of antennas to reconstruct the second message, wherein the transceiver is configured to receive the second message from two or more of the plurality of devices via distributed space-time coding by contemporaneously receiving a respective code derived from a data vector from each of the two or more of the plurality of devices. - View Dependent Claims (13, 14)
