Abstract
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.
Claims18
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.
A receiver circuit, comprising:
- a first unit configured to receive a composite signal comprising non-interfered data resource elements and interfered data resource elements from a plurality of radio cells;
- a second unit configured to determine a first mutual information metric based on the non-interfered data resource elements;
- a third unit configured to determine a second mutual information metric based on the interfered data resource elements;
- and
- a fourth unit configured to determine effective mutual information based on a combination of the first mutual information metric and the second mutual information metric;
- wherein the third unit is configured to determine the second mutual information metric based on a noise and interference covariance matrix of the interfered data resource elements subject to an antenna port and a cell-specific reference signal shift configuration;
- and
- a baseband circuit associated with the receiver circuit, to determine for each precoder and each rank, a maximum weighted mutual information based on the effective mutual information subject to a maximum criterion with respect to modulation types.
A mobile device, comprising:
- a receiver circuit configured to receive a composite signal comprising non-interfered data resource elements and interfered data resource elements from a plurality of radio cells;
- a baseband circuit configured to determine a first mutual information metric based on the non-interfered data resource elements, a second mutual information metric based on the interfered data resource elements and effective mutual information based on a combination of the first mutual information metric and the second mutual information metric;
- a transmitter circuit configured to modulate a baseband signal comprising the effective mutual information on a radio frequency carrier and to transmit the modulated baseband signal through an air link to a base station;
- wherein the baseband circuit is configured to determine the second mutual information metric based on a noise and interference covariance matrix of the interfered data resource elements subject to an antenna port and a cell-specific reference signal shift configuration;
- wherein the baseband circuit determines for each precoder and each rank, a maximum weighted mutual information based on the effective mutual information subject to a maximum criterion with respect to modulation type.
