Abstract

Methods and apparatus for configuring a UE to assist in mitigating network congestion include determining whether a data packet has expired based on a first parameter, which indicates an expiration of the data, and adjusting a transmission of the data packet based on the determination of whether the data packet has expired. In some aspects, the UE may drop the data packet upon determination that the data packet has expired. The UE may be configured detect to a first congestion level, receive a second congestion level from a second UE, and process a frame for transmission based on the first or second congestion level. The UE may be configured determine a priority, generate a data packet that includes a destination parameter or a source parameter, adjust radio resource parameters based on the destination parameter or source parameter, and transmit data packets according to adjusted radio resources.

First claim

What is claimed is:

1. A method of wireless communication of a user equipment (UE), comprising:
determining at least one priority parameter associated with a data packet, the at least one priority parameter including a first parameter that indicates an expiration of the data packet and a second parameter that indicates a transmission classification of the data packet, wherein the first parameter includes a date stamp that indicates the age of the data packet, wherein the second parameter includes one of a drop expired packet indication or a transmit expired packet indication;
determining whether the data packet has expired based on the first parameter; and
adjusting a transmission of the data packet based on the determination of whether the data packet has expired, wherein the adjusting the transmission of the data packet is based on the second parameter.

2. The method of claim 1 , further comprising dropping the data packet upon determining that the data packet has expired, wherein dropping the data packet corresponds to refraining from transmitting the data packet.

3. The method of claim 1 , further comprising transmitting the data packet, upon determining that the data packet is not expired and based on the second parameter.

4. The method of claim 1 , wherein the second parameter includes congestion thresholds for determining whether to drop the data packet or to transmit the data packet based on a congestion level.

5. The method of claim 4 , wherein the congestion thresholds include at least three levels.

6. The method of claim 1 , wherein the UE is coupled to a vehicle as part of a proximity-based service.

7. A user equipment (UE) for wireless communication, comprising:
means for determining at least one priority parameter associated with a data packet, the at least one priority parameter including a first parameter that indicates an expiration of the data packet and a second parameter that indicates a transmission classification of the data packet, wherein the first parameter includes a date stamp that indicates the age of the data packet, wherein the second parameter includes one of a drop expired packet indication or a transmit expired packet indication;
means for determining whether the data packet has expired based on the first parameter; and
means for adjusting a transmission of the data packet based on the determination of whether the data packet has expired, wherein the means for adjusting the transmission of the data packet is based on the second parameter.

8. The UE of claim 7 , further comprising means for dropping the data packet upon determining that the data packet has expired, wherein the means for dropping the data packet is configured to refrain from transmitting the data packet.

9. The UE of claim 7 , further comprising means for transmitting the data packet upon determination that the data packet is not expired and based on the second parameter.

10. The UE of claim 7 , wherein the second parameter includes congestion thresholds for determining whether to drop the data packet or to transmit the data packet based on a congestion level.

11. The UE of claim 10 , wherein the congestion thresholds include at least three levels.

12. The UE of claim 7 , wherein the UE is coupled to a vehicle as part of a proximity-based service.

13. A user equipment (UE) for wireless communication, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
determine at least one priority parameter associated with a data packet, the at least one priority parameter including a first parameter that indicates an expiration of the data packet and a second parameter that indicates a transmission classification of the data packet, wherein the first parameter includes a date stamp that indicates the age of the data packet, wherein the second parameter includes one of a drop expired packet indication or a transmit expired packet indication;
determine whether the data packet has expired based on the first parameter; and
adjust a transmission of the data packet based on the determination of whether the data packet has expired, wherein to adjust the transmission of the data packet based on the second parameter.

14. The UE of claim 13 , wherein the at least one processor is further configured to drop the data packet upon determination that the data packet has expired, wherein the configuration to drop the data packet corresponds to a configuration to refrain from transmitting the data packet.

15. The UE of claim 13 , wherein the at least one processor is further configured to transmit the data packet upon determination that the data packet is not expired and based on the second parameter.

16. The UE of claim 13 , wherein the second parameter includes congestion thresholds for determining whether to drop the data packet or to transmit the data packet based on a congestion level.

17. The UE of claim 16 , wherein the congestion thresholds include at least three levels.

18. The UE of claim 13 , wherein the UE is coupled to a vehicle as part of a proximity-based service.

19. A non-transitory computer-readable medium storing computer executable code for a user equipment (UE), comprising code to:
determine, at a UE, at least one priority parameter associated with a data packet, the at least one priority parameter includes a first parameter that indicates an expiration of the data packet and a second parameter that indicates a transmission classification of the data packet, wherein the first parameter includes a date stamp that indicates the age of the data packet, wherein the second parameter includes one of a drop expired packet indication or a transmit expired packet indication;
determine whether the data packet has expired based on the first parameter; and
adjust a transmission of the data packet based on the determination of whether the data packet has expired, wherein to adjust the transmission of the data packet based on the second parameter.
