Asymmetric constellations for channel characterization

A network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
• receive, from a user equipment (UE), a capability message indicating a capability of the UE to support asymmetric modulation constellations;
• transmit, to the UE, in response to receiving the capability message, a message indicating a configuration of an asymmetric modulation constellation for demodulation of at least one wireless data signal from the network entity;
• modulate data symbols based at least in part on the configuration of the asymmetric modulation constellation;
• and
• transmit a wireless data signal to the UE, the wireless data signal comprising the data symbols modulated in accordance with the asymmetric modulation constellation.

A method for wireless communications by a user equipment (UE), comprising:

• receiving, from a network entity, a message indicating a configuration of an asymmetric modulation constellation for demodulation of at least one wireless data signal from the network entity;
• receiving a wireless data signal from the network entity, the wireless data signal comprising data symbols modulated in accordance with the asymmetric modulation constellation;
• and
• demodulating the data symbols of the wireless data signal based at least in part on a channel characterization estimate of the wireless data signal, the channel characterization estimate associated with the configuration of the asymmetric modulation constellation.
