Forward error correction adjustments for c-v2x communications

Abstract

A user equipment (e.g., C-V2X user equipment) can receive a transmission from a network device of a mobile network and decode the transmission using a first forward error correction code. The user equipment can determine an attribute of the transmission to determine a condition of the communication channel. Based on the condition of the communication channel, the user equipment can facilitate transmitting feedback to the network device, wherein the feedback is forwarded through the mobile network to an application server device that selects a second forward error correction code based on the feedback. The second forward error correction code can be transmitted to, and received by, the user equipment. The user equipment can use the second forward error correction code to decode subsequent transmissions.

What is claimed is: 
     
         1 . A method, comprising:
 determining, by a user equipment comprising a processor, an attribute associated with a first transmission received by the user equipment via a communication channel and decoded using a first forward error correction code;   based on the attribute of the first transmission, selecting, by the user equipment, a second forward error correction code to employ for a second transmission via the communication channel to modify the attribute associated with the second transmission; and   sending, by the user equipment, the second forward error correction code to network equipment.   
     
     
         2 . The method of  claim 1 , further comprising receiving, by the user equipment, from the network equipment, an acknowledgement of the network equipment having received the second forward error correction code. 
     
     
         3 . The method of  claim 2 , further comprising receiving, by the user equipment, the second transmission via the communication channel using the second forward error correction code. 
     
     
         4 . The method of  claim 1 , wherein the attribute corresponds to a bandwidth of the communication channel. 
     
     
         5 . The method of  claim 1 , wherein the attribute corresponds to a signal-to-noise ratio of the communication channel. 
     
     
         6 . The method of  claim 1 , wherein the attribute corresponds to an error rate of the communication channel. 
     
     
         7 . The method of  claim 1 , wherein the attribute corresponds to a latency of the communication channel. 
     
     
         8 . A user equipment, comprising:
 a processor; and   a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
 determining a characteristic associated with a first transmission received by the user equipment on a communication channel and decoded using a first forward error correction code; 
 based on the characteristic of the first transmission, selecting a second forward error correction code to employ for a second transmission on the communication channel to adjust the characteristic associated with the second transmission; and 
 transmitting the second forward error correction code to network equipment. 
   
     
     
         9 . The user equipment of  claim 8 , wherein the operations further comprise receiving, from the network equipment, a confirmation of the second forward error correction code. 
     
     
         10 . The user equipment of  claim 9 , wherein the operations further comprise receiving the second transmission on the communication channel using the second forward error correction code. 
     
     
         11 . The user equipment of  claim 8 , wherein the characteristic corresponds to a bandwidth of the communication channel. 
     
     
         12 . The user equipment of  claim 8 , wherein the characteristic corresponds to a signal-to-noise ratio of the communication channel. 
     
     
         13 . The user equipment of  claim 8 , wherein the characteristic corresponds to an error rate of the communication channel. 
     
     
         14 . The user equipment of  claim 8 , wherein the characteristic corresponds to a latency of the communication channel. 
     
     
         15 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a mobile device, facilitate performance of operations, comprising:
 determining a condition associated with a first transmission received by the mobile device via a communication channel and decoded using a first forward error correction code;   based on the condition of the first transmission, selecting a second forward error correction code to employ for a second transmission via the communication channel to improve the condition associated with the second transmission; and   communicating the second forward error correction code to network equipment.   
     
     
         16 . The non-transitory machine-readable medium of  claim 15 , wherein the operations further comprise receiving, from the network equipment, a confirmation of the second forward error correction code. 
     
     
         17 . The non-transitory machine-readable medium of  claim 16 , further comprising receiving the second transmission via the communication channel using the second forward error correction code. 
     
     
         18 . The non-transitory machine-readable medium of  claim 15 , wherein the condition corresponds to a bandwidth of the communication channel. 
     
     
         19 . The non-transitory machine-readable medium of  claim 15 , wherein the condition corresponds to a signal-to-noise ratio of the communication channel. 
     
     
         20 . The non-transitory machine-readable medium of  claim 15 , wherein the condition corresponds to an error rate of the communication channel.
