Abstract: In addition to the normal modulation states of 5G and 6G (BPSK, QPSK, 16QAM, etc.), the modulation scheme may include one or more zero-power states in which an amplitude is transmitted with very low or zero power. The receiver can detect the zero-power state and treat that state as an additional modulation state of the modulation scheme, thereby increasing the information content of each message element due to the additional number of modulation states available for encoding. Alternatively, the zero-power state or states may be used for special options, such as indicating a beginning or an ending of the message. Zero-power states may also be used to separate the message from an associated demodulation reference or to separate sequential messages. Substantial power may be saved since the zero-power states require very little (or no) transmitter power.
