Method for vehicle-to-vehicle communication

A method of a first transportation vehicle for vehicle-to-vehicle (V2V) communication, the method comprising:

• receiving, within a transmission area of the second transportation vehicle, a first message from a second transportation vehicle comprising first channel quality information (CQI) related to a first position indicated in the message;
• comparing the first CQI with a second CQI related to a second position, wherein the second CQI is determined by the first transportation vehicle;
• and
• wherein the second position is identical to the first position or within a predetermined range about the first position,
• wherein the first transportation vehicle transmits the first CQI to a third transportation vehicle in response to a difference between the first CQI and the second CQI being below a first predetermined CQI threshold and wherein the first transportation vehicle transmits the second CQI to the third transportation vehicle in response to a difference between the first CQI and the second CQI being below a second predetermined CQI threshold.

A non-transitory computer readable medium including a computer program comprising instructions which, when the program is executed by a control unit of a transportation vehicle, cause the control unit to carry out a method of a first transportation vehicle for vehicle-to-vehicle (V2V) communication with a second transportation vehicle, the method comprising:

• receiving, within a transmission area of the second transportation vehicle, a first message from a second transportation vehicle comprising first channel quality information (CQI) related to a first position indicated in the message;
• comparing the first CQI with a second CQI related to a second position, wherein the second CQI is determined by the first transportation vehicle;
• and
• selectively transmitting a second message comprising the first CQI to a third transportation vehicle based on the comparison of the first CQI and the second CQI, the selection comprising determining a difference between the first COI and the second COI relative to a first predetermined COI threshold,
• selectively transmitting a third message comprising the second COI to the third transportation vehicle based on the comparison of the first COI and the second COI, the selection comprising determining a difference between the first COI and the second COI relative to a second predetermined COI threshold,
• wherein the second position is identical to the first position or within a predetermined range about the first position.

A non-transitory computer readable medium including a computer program comprising instructions which, when the program is executed by a control unit of a first transportation vehicle, cause the control unit to carry out a method of a second transportation vehicle for vehicle-to-vehicle (V2V) communication, the method comprising:

• determining first channel quality information (CQI) related to a first position;
• and
• transmitting a first message to a first transportation vehicle within a transmission area of the second transportation vehicle, the first message comprising the first CQI,
• wherein the second transportation vehicle transmits the first message in response to the second transportation vehicle and/or the first transportation vehicle being within a predetermined distance threshold about the first position,
• transmitting the first CQI to a third transportation vehicle in response to a difference between the first CQI and a second CQI being below a first predetermined CQI threshold and transmitting the second CQI to the third transportation vehicle in response to a difference between the first CQI and the second CQI being below a second predetermined CQI threshold.

A method for communication between a first, a second, and a third transportation vehicle, for vehicle-to-vehicle (V2V) communication, the method comprising:

• determining first channel quality information (CQI) related to a first position;
• and
• transmitting a first message to a first transportation vehicle within a transmission area of the second transportation vehicle, the first message comprising the first CQI,
• wherein the second transportation vehicle transmits the first message in response to the second transportation vehicle and/or the first transportation vehicle being within a predetermined distance threshold about the first position,
• wherein the first transportation vehicle transmits the first CQI to a third transportation vehicle in response to a difference between the first CQI and a second CQI being below a first predetermined CQI threshold, and
• wherein the first transportation vehicle transmits the second CQI to the third transportation vehicle in response to a difference between the first CQI and the second CQI being below a second predetermined CQI threshold.
