1. A first network entity for wireless communication, comprising:
one or more communication interfaces; and
one or more processors coupled to the one or more communication interfaces, wherein the first network entity is configured to:
receive, via the one or more communication interfaces and from a second network entity, an indication of a first frequency offset associated with the second network entity;
receive, via the one or more communication interfaces and from the second network entity, a first transmission including a first communication and a first helper signal that are separated in a frequency domain based on the first frequency offset; and
decode, via envelope tracking, the first transmission to obtain the first communication from the first transmission.
