Inter-channel encoding and decoding of multiple high-band audio signals

A method of communication comprising:

• generating, at a device, a first high-band portion of a first signal based on a left signal and a right signal;
• generating, at the device, a set of adjustment gain parameters based on a high-band non-reference signal, the high-band non-reference signal corresponding to one of a left high-band portion of the left signal or a right high-band portion of the right signal as a high-band non-reference signal;
• and
• transmitting, from the device, information corresponding to the first high-band portion of the first signal, and the set of adjustment gain parameters.

A computer-readable storage device storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• generating a first high-band portion of a first signal based on a left signal and a right signal;
• generating a set of adjustment gain parameters based on a high-band non-reference signal, the high-band non-reference signal corresponding to one of a left high-band portion of the left signal or a right high-band portion of the right signal as a high-band non-reference signal;
• and
• causing transmission of information corresponding to the first high-band portion of the first signal, and the set of adjustment gain parameters.

An apparatus comprising:

• means for generating a first high-band portion of a first signal based on a left signal and a right signal;
• means for generating a set of adjustment gain parameters based on a high-band non-reference signal, the high-band non-reference signal corresponding to one of a left high-band portion of the left signal or a right high-band portion of the right signal as a high-band non-reference signal;
• and
• means for transmitting information corresponding to the first high-band portion of the first signal, and a set of adjustment gain parameters corresponding to the high-band non-reference signal.
