Abstract: A transmitting apparatus and a transmitting method are provided. The transmitting apparatus comprises: an encoder configured to encode data for a plurality of user equipments into corresponding encoded signals, respectively; a modulator configured to perform a joint modulation on the encoded signals for the plurality of user equipments to generate modulated signals, wherein the modulator performs the joint modulation by mapping bits of the encoded signals for the plurality of user equipments to a symbol corresponding to each constellation point of a constellation map of the modulated signals so that respective constellation points satisfy a Gray mapping rule; a transmitter configured to transmit the modulated signals.
