  • Publication number: 20190014546
    Abstract: Embodiments of the present disclosure provide a method and apparatus for indicating power allocation in multiuser superposition transmission. The method comprises: transmitting a signaling for indicating a first power parameter and a first power offset to a first UE so that the first UE determines first power allocation information specific to it based on the first power parameter and the first power offset; and transmitting a signaling for indicating a second power parameter and a second power offset to a second UE paired with the first UE so that the second UE determines second power allocation information specific to it based on the second power parameter and the second power offset. Embodiments of the present disclosure enable the near/victim UE of paired UEs to decode an interference signal caused by far/interfering UE based on power allocation information and remove the interference signal caused by far/interfering UE to improve correctness of decoding its own physical downlink shared channel data.
