Multi-layer wireless streaming with adaptive constellation mapping (acm)

A method for transmitting a plurality of layers from a plurality of transmitters having a plurality of transmitter chains having a plurality of transmitter antennas, the method comprising:

• determining a set of candidate transmission arrangements, each candidate transmission arrangement specifying a combination of layers, transmitters, transmitter chains, and transmitter antennas;
• for each candidate transmission arrangement:
• determining a set of mapping combinations, each mapping combination applicable to the respective candidate transmission arrangement,
• determining a combined estimated received signal constellation associated each mapping combination,
• determining, a distance metric for each combined estimated received signal constellation,
• determining, for each mapping combination, a blended metric based on the distance metric associated with the respective mapping combination, and
• selecting a best one of the blended metrics;
• selecting one of the candidate transmission arrangements based on the selected blended metrics associated with each candidate transmission arrangement;
• and
• transmitting using the combination of layers, transmitters, transmitter chains, and transmitter antennas associated with the selected candidate transmission arrangement and the mapping combination associated with the selected blended metric associated with the selected candidate transmission arrangement.

An electronic device comprising:

• a plurality of transmitter chains for transmitting a plurality of layers;
• a plurality of antenna coupled to the transmitter chains;
• and
• a processor configured to
• determine, for each transmitter chain of the plurality of transmitter chains, a set of mapped constellations by applying a set of mapping options, each mapping option associated with the each of the transmitter chains, to a signal constellation associated with the each of the transmitter chains;
• determine for each mapping option of the set of mapping options associated with the each of the transmitter chains, estimated received constellations using the set of mapped constellations associated with the each of the transmitter chain and an estimated channel transfer function used by the each of the transmitter chain;
• determine a set of mapping combinations, each mapping combination including one mapping option of the set of mapping options associated with each transmitter chain of the plurality of transmitter chains;
• determine, a set of combined estimated received constellations, each combined estimated received constellation being a combination of the estimated received constellations associated with one of the mapping combinations;
• determine a distance metric for each combined estimated received constellation;
• determine a set of blended metrics, each blended metric associated with one of the mapping combinations, each blended metric based on the distance metric associated with the respective mapping combination;
• and
• determine a transmission format using the set of blended metrics, wherein the transmitter chains transmit using the determined transmission format.
