Facilitating fast channel state information computation for 5G wireless communication systems

Network node equipment, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• transmitting a request to a user equipment to determine channel state information based on a demodulation reference signal;
• receiving, from the user equipment, the channel state information, wherein the channel state information comprises wideband channel state information associated with a wideband configuration that has been transmitted via radio resource control signaling;
• based on the channel state information, determining a parameter for a data channel transmission to the user equipment;
• transmitting the parameter to the user equipment via a downlink control channel;
• determining, by the user equipment, wideband channel state information and sub-band channel state information associated with a communication link;
• and
• receiving an offset value, from the user equipment, wherein the offset value is based on a difference between the wideband channel state information and the sub-band channel state information.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• receiving a demodulation reference signal to facilitate channel estimation for a data channel of a communication link with network node equipment;
• receiving a physical downlink shared channel signal to facilitate channel estimation for the data channel of the communication link with the network node equipment;
• in response to receiving the demodulation reference signal and the physical downlink shared channel signal, estimating channel state data;
• decoding the physical downlink shared channel signal and a channel quality indicator in a same slot;
• in response to estimating the channel state data, transmitting the channel state data to the network node equipment, wherein the transmitting comprises transmitting, via radio resource control signaling, wideband channel state data associated with a wideband configuration;
• determining sub-band channel state data associated with the communication link;
• and in response to determining the sub-band channel state data, determining an offset value, wherein the offset value is a difference between the wideband channel state data and the sub-band channel state data.
