Computing channel state information in a 5G wireless communication system in 4G spectrum frequencies

A user equipment, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
• obtaining information at a new radio component indicating whether long term evolution-new radio coexistence is in use in a cell in which the user equipment is operating;
• determining, based on the information, whether long term evolution-new radio coexistence is in use;
• in response to determining that long term evolution-new radio coexistence is in use,
• obtaining first overhead data corresponding to long term evolution signals and new radio signals, and
• determining channel state information reference resources based on removing the first overhead data of the long term evolution signals and new radio signals from channel state information computation data, wherein the determining comprises computing a link-quality metric, using the link-quality metric to obtain a precoding matrix indicator and a rank indicator, and estimating a channel quality indicator based on the precoding matrix indicator and the rank indicator;
• and
• in response to determining that long term evolution-new radio coexistence is not in use,
• obtaining second overhead data of new radio signals, and
• determining channel state information reference resources by removing the second overhead data of the new radio signals from channel state information computation data.
