Abstract

Embodiments of a system and method for dual connectivity for device to vehicle or vehicle to vehicle communication in a Wireless Network are generally described herein. In some embodiments, processing circuitry may determine a quality of service (QoS) level for data to be transmitted over a first radio access technology (RAT) connection and determine a QoS indicator from the QoS level, the QoS indicator identifying a dual connectivity backup transmission, the dual connectivity backup transmission including a hot, warm, or cold backup. In some embodiments, transceiver circuitry may attempt to transmit the data using a first transmission mode, the first transmission mode using the first RAT connection and the data including the QoS indicator and retransmit, in response to the attempt failing, the data using a second transmission mode.

Claims (41)

1. An apparatus, comprising:

a processor configured to cause a user equipment (UE) to:

identify a data session to be duplicated based at least in part on an importance level of the data session;

wherein a connection structure for the data session to be duplicated includes duplication of the data session above access stratum (AS) layers;

wherein the AS layers include at least packet data convergence protocol (PDCP) and physical (PHY) layers;

initiate transmission of data associated with the data session using a first transmission mode to a first transmission point, wherein the first transmission mode uses a first radio access technology (RAT); and

initiate transmission of the data associated with the data session using a second transmission mode to a second transmission point, wherein the second transmission mode uses a second RAT, wherein the second RAT is different than the first RAT;

wherein the first RAT to the first transmission point and the second RAT to the second transmission point establish dual connectivity in which the UE is configured for use of a primary radio link and a secondary radio link for transmission.

2. The apparatus of claim 1 , wherein the second RAT used by the second transmission mode is same as the first RAT used by the first transmission mode.

3. The apparatus of claim 1 , wherein the first RAT operates on a 3GPP LTE network and the second RAT operates on a 5G network.

4. The apparatus of claim 1 , wherein the data session is duplicated in response to determining a quality of service (QOS) level of the data session.

5. The apparatus of claim 1 , wherein the first transmission mode uses a first carrier and the second transmission mode uses a second carrier, wherein the first carrier is different from the second carrier.

6. The apparatus of claim 1 , wherein the first transmission mode and the second transmission mode use a same carrier.

7. The apparatus of claim 1 , wherein the first transmission point and the second transmission point are the same.

8. The apparatus of claim 1 , wherein the first transmission mode operates at a frequency below 6 GHz and the second transmission mode operates at or above 6 GHz.

9. The apparatus of claim 1 , wherein transmissions for the first transmission mode and the second transmission mode occur simultaneously.

10. The apparatus of claim 1 , wherein the first transmission mode and the second transmission mode take place at different times without regard to overlap.

11. A non-transitory computer-readable storage medium storing program instructions executable by one or more processors of a user equipment (UE) to configure the UE to perform operations to:

identify a data session to be duplicated based at least in part on an importance level of the data session;

wherein a connection structure for the data session to be duplicated includes duplication of the data session above access stratum (AS) layers;

wherein the AS layers include at least PDCP and PHY layers;

initiate transmission of data associated with the data session using a first transmission mode to a first transmission point, wherein the first transmission mode uses a first radio access technology (RAT); and

initiate transmission of the data associated with the data session using a second transmission mode to a second transmission point, wherein the second transmission mode uses a second RAT, wherein the second RAT is different than the first RAT;

wherein the first RAT to the first transmission point and the second RAT to the second transmission point establish dual connectivity in which the UE is configured for use of a primary radio link and a secondary radio link for transmission.

12. The non-transitory computer-readable storage medium of claim 11 , wherein the second RAT is same as the first RAT.

13. The non-transitory computer-readable storage medium of claim 11 , wherein the first RAT operates on a 3GPP LTE network and the second RAT operates on a 5G network.

14. The non-transitory computer-readable storage medium of claim 11 , wherein the first transmission mode and the second transmission mode use a same carrier frequency for transmission.

15. The non-transitory computer-readable storage medium of claim 11 , wherein transmissions for the first transmission mode and the second transmission mode occur simultaneously.

16. A wireless device, comprising:

wireless communication circuitry; and

at least one processor coupled to the wireless communication circuitry and configured to cause the wireless device to:

identify a data session to be duplicated based at least in part on an importance level of the data session;

wherein a connection structure for the data session to be duplicated includes duplication of the data session above access stratum (AS) layers;

wherein the AS layers include at least packet data convergence protocol (PDCP) and physical (PHY) layers;

initiate transmission of data associated with the data session using a first transmission mode to a first transmission point, wherein the first transmission mode uses a first radio access technology (RAT); and

initiate transmission of the data associated with the data session using a second transmission mode to a second transmission point, wherein the second transmission mode uses a second RAT, wherein the second RAT is different than the first RAT;

wherein the first RAT to the first transmission point and the second RAT to the second transmission point establish dual connectivity in which the UE is configured for use of a primary radio link and a secondary radio link for transmission.

17. The wireless device of claim 16 , wherein the first RAT operates on a 3GPP LTE network and the second RAT operates on a 5G network.

18. The wireless device of claim 16 , wherein the data session is duplicated in response to determining a quality of service (QOS) level of the data session.

19. The wireless device of claim 16 , wherein the first transmission mode uses a first carrier and the second transmission mode uses a second carrier, and wherein the first carrier is different from the second carrier.

20. The wireless device of claim 16 , wherein transmissions for the first transmission mode and the second transmission mode occur simultaneously.
