Facilitation of computational complexity reduction for periodic and aperiodic channel state information reporting in 5G or other next generation network

A system, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• based on ranking information associated with periodically received channel state data and an indication that a mobile device is to report in an aperiodic reporting mode, sending selection data indicative of a group of vectors of a codebook data structure over which the mobile device is to search when selecting transmission parameters for operation according to an aperiodic reporting mode of the mobile device;
• and
• in response to sending reference signal data, associated with a reference signal, to the mobile device, aperiodically receiving the channel state data associated with a channel of the mobile device according to the aperiodic reporting mode of the mobile device, resulting in aperiodically received channel state data.

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

• in response to sending reference signal data to a mobile device, receiving first channel state data according to a periodic configuration supported by the mobile device, wherein the first channel state data comprises ranking data representative of ranks that prioritize different transmission layers represented by a codebook data structure;
• based on a rank of the ranks of the first channel state data, facilitating an aperiodic configuration supported by the mobile device during which the mobile device reports channel state data aperiodically according to aperiodic requests received by the mobile device;
• and
• following an aperiodic request having been received by the mobile device, receiving second channel state data according to the aperiodic configuration in response to the aperiodic request.
