Facilitation of rank and precoding matrix indication determinations for multiple antenna systems with aperiodic channel state information reporting in 5G or other next generation networks

A method, comprising:

• generating, by a device comprising a processor, an aperiodic channel state information report based on selected data derived from a periodic channel state information report;
• and
• facilitating, by the device, a transmission of the aperiodic channel state information report to a network device of a communications network, wherein the selected data comprises first rank information of the periodic channel state information report and a first precoding matrix index of the periodic channel state information report, and wherein generating the aperiodic channel state information report comprises reducing a complexity associated with aperiodic reporting based on determining second rank information and a second precoding matrix index for the aperiodic reporting based on the first rank information and the first precoding matrix index.

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

• determining first channel state data of a channel based on selected data from second channel state data of the channel, wherein the second channel state data is received prior to the determining the first channel state data, and wherein the first channel state data is based on a periodic configuration of a user equipment, and wherein the determining comprises determining the first channel state data based on the periodic configuration of the user equipment;
• and
• transmitting, to network equipment, an aperiodic channel state information report that comprises the first channel state data.
