1. A device, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
determining different modulation indexes for a code rate of a data transmission to be sent to the device by network equipment in accordance with using a multiple-input and multiple-output communication protocol with a group of layers;
generating a first pair comprising the code rate and a first modulation index of the different modulation indexes;
generating a second pair comprising the code rate and a second modulation index of the different modulation indexes;
mapping the first pair to a first layer of the group of layers based on signal interference values associated with respective layers of the group of layers;
mapping the second pair to a second layer of the group of layers based on the signal interference values;
sending recommendation information to the network equipment identifying the different modulation indexes for the code rate, the first pair, the second pair, the first layer to which the first pair is mapped, and the second layer to which the second pair is mapped; and
based on the sending, receiving the data transmission from the network equipment in accordance with a scheduling configuration determined based on the recommendation information.
