1. A network node device, comprising:

  • a processor; and

    a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

    determining a metric representative of a shift in a received frequency of a signal determined to have been received by a user equipment and an actual frequency determined to have been used to transmit the signal;

    in response to the metric being determined to exceed a threshold, facilitating transmitting, to the user equipment, a message instructing the user equipment to enable a reception of transmission signals having a precoding rank value of one, wherein the precoding rank value of one indicates transmissions of data comprising same content concurrently from the network node device to the user equipment;

    facilitating transmitting, to the user equipment, a reference signal specific to the user equipment and having the precoding rank value of one;

    receiving, from the user equipment, feedback comprising an indicator of channel quality applicable to a quality of a channel between the network node device and the user equipment;

    based on the indicator of channel quality, determining a transmission scheduling parameter related to a transmission protocol for further transmissions from the network node device to the user equipment; and

    facilitating transmitting, to the user equipment, the transmission scheduling parameter.
