Systems and methods for enhanced rate adaptation in 5g

An apparatus for performing enhanced rate adaptation by a radio access network (RAN) node, the apparatus comprising:

• a memory storing instructions;
• and
• at least one processor configured to execute the instructions to:
• determine a first code rate, for sending one or more messages to a user equipment (UE) before a first time, based at least in part on a first rank and a first message error rate;
• send the one or more messages to the UE before the first time using the first code rate;
• receive channel quality information and a second rank from the UE at the first time, wherein the second rank is different than the first rank;
• determine a second code rate, for sending one or more messages to the UE after the first time and before a second time, based at least in part on the received channel quality information and second rank;
• and
• send the one or more messages to the UE, after the first time and before a second time, using the second code rate.

A non-transitory computer-readable medium for storing computer readable program code or instructions for carrying out operations, when executed by a processor, for enhanced rate adaptation (RA), the operations comprising:

• determining a first code rate, for sending one or more messages to a user equipment (UE) before a first time, based at least in part on a first rank and a first message error rate;
• sending the one or more messages to the UE before the first time using the first code rate;
• receiving channel quality information and a second rank from the UE at the first time, wherein the second rank is different than the first rank;
• determining a second code rate, for sending one or more messages to the UE after the first time and before a second time, based at least in part on the received channel quality information and second rank;
• and
• sending the one or more messages to the UE, after the first time and before a second time, using the second code rate.
