1. A method comprising:
communicating, in a wireless communication network, signaling that is indicative of multiple modulation domains for overlaid modulation of data and is indicative of multiple modulation switching intervals, the multiple modulation domains being different from each other, the multiple modulation switching intervals comprising a respective modulation switching interval at which modulation elements associated with each of the multiple modulation domains may be switched, each respective modulation switching interval being different from other modulation switching intervals in the multiple modulation switching intervals;
communicating data, that is modulated using the overlaid modulation, in the wireless communication network, the communicating comprising communicating data that is modulated using a first modulation domain of the multiple modulation domains and a second modulation domain of the multiple modulation domains,
wherein
communicating signaling comprises communicating first signaling that is indicative of the first modulation domain and is indicative of a first modulation switching interval at which modulation elements associated with the first modulation domain may be switched;
the method further comprises communicating data that is modulated using the first modulation domain;
communicating signaling further comprises communicating second signaling that is indicative of the second modulation domain and is indicative of a second modulation switching interval at which modulation elements associated with the second modulation domain may be switched;
communicating data that is modulated using the overlaid modulation comprises, subsequent to communicating the second signaling, communicating data that is modulated using the first modulation domain and the second modulation domain.
