Methods and devices for determining effective mutual information

摘要

A method includes receiving at a receiver circuit a composite signal including non-interfered data resource elements and interfered data resource elements from a plurality of radio cells, and determining a first mutual information metric based on the non-interfered data resource elements. The method further includes determining a second mutual information metric based on the interfered data resource elements, and determining effective mutual information based on a combination of the first mutual information metric and the second mutual information metric.

1. A method, comprising:
receiving at a receiver circuit a composite signal comprising non-interfered data resource elements and interfered data resource elements from a plurality of radio cells; determining a first mutual information metric based on the non-interfered data resource elements; determining a second mutual information metric based on the interfered data resource elements; and determining effective mutual information based on a combination of the first mutual information metric and the second mutual information metric; determining for each precoder in a baseband circuit associated with the receiver circuit, and each rank, a maximum weighted mutual information based on the effective mutual information subject to a maximum criterion with respect to modulation types.
