Communication of channel state information (CSI) in wireless networks

A User Equipment (UE) for communicating channel state information (CSI), the UE comprising:

• physical layer (PHY) circuitry configured to receive, from a radio access network (RAN), a communication signal traversing through a communication channel;
• and
• processor circuitry configured to:
• develop a plurality of channel coefficients describing a channel response of the communication channel at a plurality of discrete intervals of time,
• assign the plurality of channel coefficients to corresponding priorities from among a plurality of priorities, and
• selectively include or exclude channel coefficients from among the plurality of channel coefficients into a CSI report based upon the corresponding priorities,
• wherein the PHY circuitry is further configured to transmit the CSI report to the RAN.

An access node for communicating channel state information (CSI), the access node comprising:

• processor circuitry configured to:
• allocate a plurality of resources within a communication channel to be utilized by a User Equipment (UE) to provide a CSI report, and
• trigger the UE to provide the CSI report associated with a communication signal that traverses through the communication channel;
• and
• physical layer (PHY) circuitry configured to receive the CSI report from the UE,
• wherein the CSI report includes a first plurlaity of channel coefficients from among a plurlaity of channel coefficients describing a channel response of the communication channel at a plurality of discrete intervals of time,
• wherein the plurality of channel coefficients are assigned corresponding priorities from among a plurality of priorities,
• wherein the first plurlaity of channel coefficients are selectively included within the CSI report based upon their corresponding priorities from among the plurality of priorities and the plurality of resources allocated by a radio access network (RAN), and
• wherein a second plurlaity of channel coefficients from among the plurlaity of channel coefficients are selectively excluded form the CSI report based upon their corresponding priorities from among the plurality of priorities and the plurality of resources allocated by the RAN.
