Systems and methods to enhance radio link performance in a multi-carrier environment

A device, comprising:

• a non-transitory memory having a program stored thereon;
• and
• a processor executing the program, wherein the execution of the program causes the processor to perform operations comprising:
• sending, by a media access control (“MAC”) layer of a wireless device to an upper level layer of the wireless device, a request for packets having a predetermined level of priority;
• sending, by the upper level layer, data in a packet for transmission, wherein the packet includes an indication of a level of priority of the packet, wherein the indicated level of priority satisfies the predetermined level of priority, and
• receiving, by the MAC layer of the device, the packet including the indication of the level of priority provided by the upper level layer,
• identifying, by the MAC layer, a reliability of each of a plurality of component carriers, and
• selecting, by the MAC layer, one of the component carriers on which to transmit the packet, wherein the selecting is based on the level of priority of the packet and the reliability of the one of the component carriers.

A non-transitory computer readable storage medium with an executable program stored thereon, wherein the program instructs a processor to perform the following operations, comprising:

• sending, by a media access control (“MAC”) layer of a wireless device to an upper level layer of the wireless device, a request for packets having a predetermined level of priority;
• sending, by the upper level layer, data in a packet for transmission, wherein the packet includes an indication of a level of priority of the packet, wherein the indicated level of priority satisfies the predetermined level of priority;
• receiving, by the MAC layer of the wireless device, the packet including the indication of the level of priority provided by the upper level layer;
• identifying, by the MAC layer, a reliability of each of a plurality of component carriers;
• and
• selecting, by the MAC layer, one of the component carriers on which to transmit the packet, wherein the selecting is based on the level of priority of the packet and the reliability of the one of the component carriers.
