Abstract
There is provided a device including: an acquisition unit configured to acquire information on power allocation to a data signal serving as a target for multiplexing using power allocation; and a reporting unit configured to report the information on the power allocation to a terminal device.
Claims21
A device, comprising:
- a first antenna port configured to transmit a first data signal of a plurality of data signals;
- and
- at least one processor configured to:
- determine first information on power allocation for the first data signal, wherein
- the first information indicates a difference between a power allocated to the first data signal and a power allocated to a reference signal,
- the reference signal is specific to a terminal device and is transmitted by the first antenna port,
- and the first information on the power allocation is based on the first antenna port;
- execute a multiplexing operation on the first data signal based on the power allocation for the first data signal, wherein:
- the first data signal is a spatial stream signal, and
- the power allocation for the first data signal is one of:
- an adaptive power allocation based on a diagonal matrix, or
- a scalar power allocation;
- report the first information on the power allocation to the terminal device;
- and
- report a power rank of the first data signal to the terminal device, wherein the power rank corresponds to a power level of the first data signal with respect to a plurality of power levels of the plurality of data signals other than the power level of the first data signal.
