Claim of US Patent No. 10,462,801

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 and to exclude, from channel state information feedback, reporting of a rank indicator representative of a number of different data streams transmitted between the network node device and the user equipment, 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, the channel state information 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.
