Constellation shaping for multiple user multiple input multiple output

An apparatus for wireless communication at a network node, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on stored information that is stored in the at least one memory, the at least one processor, individually or in any combination, is configured to:
• output, for a first wireless device, an indication of at least one shaping operation associated with one or more additional wireless devices in a plurality of wireless devices, wherein each of the plurality of wireless devices is associated with multiple user multiple input multiple output (MU-MIMO) communication, and wherein the first wireless device is included in the plurality of wireless devices;
• generate, based on a first shaping operation associated with the first wireless device and the at least one shaping operation, a set of symbols for a DL transmission associated with the MU-MIMO communication;
• and
• output, for transmission to the plurality of wireless devices, the DL transmission.

A method of wireless communication at a first wireless device, comprising:

• receiving an indication of at least one shaping operation associated with one or more additional wireless devices in a plurality of wireless devices, wherein each of the plurality of wireless devices is associated with multiple user multiple input multiple output (MU-MIMO) communication, and wherein the first wireless device is included in the plurality of wireless devices;
• receiving a downlink (DL) transmission associated with the MU-MIMO communication;
• performing a demodulation of the DL transmission based on the indication;
• and
• outputting a result of the demodulation of the DL transmission for at least one of a transmission to at least one other wireless device or a local storage at the first wireless device.

A method of wireless communication at a network node, comprising:
