摘要：A framework is provided for generating a MA signal based on modulating atleast one first stream of bits using a first modulation type to generate at least one firstmodulated symbol from each of the at least one first stream of bits, spreading each ofthe at least one first modulated symbols using a spreading sequence that is specific to arespective first stream of bits to generate a second set of modulated symbols, mappingat least one of the second set of modulated symbols using a resource element mappingand transmitting the mapped second sets of modulated symbols as a MA signal. Thespreading of each of the at least one first modulated symbols using a spreadingsequence that is specific to a respective first stream of bits may use a layer specificspreading sequence and a layer specific sparsity pattern. The mapping of the at least oneof the second set of modulated symbols to a resource element may use a user
equipment (UE) specific and/or layer specific spreading sequence. The mapping of the atleast one of the second set of modulated symbols to a resource element may use sparsespreading.
