摘要
Various aspects of the disclosure relate to a codebook design that defines phase rotation on one or more layers of a codebook. This codebook may be used, for example, for sparse code multiple access (SCMA) encoding. One feature pertains to a method of communication that includes receiving at least one input signal, and mapping each of the at least one input signal to a corresponding layer of a codebook, where the codebook defines phase rotation between the layers. The method may further include generating a coded signal for each of the at least one input signal on each corresponding layer based on the codebook, and generating an output signal based on each generated coded signal.
