Abstract

A receiving apparatus includes a receiving section that receives a data signal, a demodulation reference signal, and a specific signal in at least one of a plurality of layers, and a control section that, based on the demodulation reference signal and the specific signal, estimates interference, controls transmission of a result of the estimation, and performs a modulo operation of the data signal.

Claims (22)

1. A receiving apparatus comprising:

a receiving section that receives a data signal, a demodulation reference signal, and a specific signal in at least one of a plurality of layers; and

a control section that, based on the demodulation reference signal and the specific signal, estimates interference, controls transmission of a result of the estimation, and performs a modulo operation of the data signal.

2. The receiving apparatus according to claim 1 , wherein

a dedicated layer in the plurality of layers is allocated to the receiving apparatus, and

the data signal in the dedicated layer and the specific signal in the dedicated layer are transmitted based on interference with the dedicated layer from a specific layer having a layer number smaller than a layer number of the dedicated layer.

3. The receiving apparatus according to claim 2 , wherein

the control section estimates interference to the dedicated layer from the specific layer, based on a signal received in a demodulation reference signal resource in the specific layer, a signal received in a demodulation reference signal resource in the dedicated layer, and a signal received in a specific signal resource in the dedicated layer.

4. The receiving apparatus according to claim 3 , wherein

the specific signal in each of the plurality of layers is transmitted by employing the modulo operation.

5. The receiving apparatus according to claim 3 , wherein

the plurality of layers are mapped to ports for the demodulation reference signals according to a certain order.

6. The receiving apparatus according to claim 2 , wherein

the specific signal in each of the plurality of layers is transmitted by employing the modulo operation.

7. The receiving apparatus according to claim 2 , wherein

the plurality of layers are mapped to ports for the demodulation reference signals according to a certain order.

8. The receiving apparatus according to claim 1 , wherein

the specific signal in each of the plurality of layers is transmitted by employing the modulo operation.

9. The receiving apparatus according to claim 8 , wherein

the plurality of layers are mapped to ports for the demodulation reference signals according to a certain order.

10. The receiving apparatus according to claim 1 , wherein

the plurality of layers are mapped to ports for the demodulation reference signals according to a certain order.
