Employing modulation layer mapping to improve performance of MIMO communication systems

A device, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• determining a code rate for a codeword of a downlink data transmission to be sent to the device by network equipment, wherein the device and the network equipment are configured to communicate using a multiple-input and multiple-output communication protocol with a group of layers;
• determining different modulation indexes for the code rate based on signal-to-noise plus interference ratios associated with respective layers of the group of layers, wherein the different modulation indexes comprise a first modulation index and a second modulation index;
• generating different modulation index and code rate pairs using the different modulation indexes and the code rate, comprising generating a first pair that comprises the first modulation index and the code rate and generating a second pair that comprises the second modulation index and the code rate;
• mapping the different modulation index and code rate pairs to different subsets of layers of the group of layers based on the different modulation indexes and the signal-to-noise plus interference ratios;
• sending channel state information, to the network equipment, identifying the different modulation indexes for the code rate, the different modulation index and code rate pairs, and the different subsets of layers to which the different modulation index and code rate pairs are mapped;
• and
• based on sending the channel state information, receiving the downlink data transmission from the network equipment in accordance with a scheduling configuration determined based on the channel state information.
