Apparatus including a transmission processing unit that generates transmission signal sequences of multiple power layers

An apparatus, comprising:

• an acquirer that acquires a unique descrambler corresponding to the apparatus for which a transmission signal sequence of a power layer is destinated, wherein each power layer among multiple power layers that are to be multiplexed using power allocation, and wherein the multiple power layers are all different;
• and
• a reception processor that performs a reception process using the descrambler corresponding to the apparatus for which the transmission signal sequence of the power layer is destinated,
• wherein all of the multiple power layers are different from each other,
• wherein the reception processor receives the signal sequence of the multiple power layers,
• wherein the reception processor determines a power layer of which the transmission signal sequence is to be processed using a scrambler corresponding to the apparatus for which the transmission signal sequence of the power layer is destinated,
• wherein the apparatus further comprises a notificator that receives a notification of the power layer of which the transmission signal sequence is destinated for the apparatus, and
• wherein the notificator receives the notification of the power layer through downlink control information destined for the apparatus.
