Abstract
Provided is a device including an acquisition unit to acquire that acquires information indicating a layer allocated to a terminal device among a plurality of layers that are subject to non-orthogonal multiplexing using a codebook and a reporting unit that reports the layer to the terminal device.
Claims16
A device, comprising:
- at least one processor configured to:
- allocate at least one layer of a plurality of layers to a terminal device;
- change, based on a change in traffic, a number of layers of the plurality of layers,
- wherein the plurality of layers are subjected to a non-orthogonal multiplexing operation based on a codebook;
- acquire information that indicates the at least one layer of the plurality of layers is allocated to the terminal device;
- select one of a first codebook group of a plurality of codebook groups or a second codebook group of the plurality of codebook groups based on a first number of layers of the first codebook group and a second number of layers of the second codebook group,
- wherein the second number of layers is smaller than the first number of layers;
- transmit the at least one layer and the selected one of the first codebook group or the second codebook group, to the terminal device;
- and
- transmit data associated with the at least one layer based on the selected one of the first codebook group or the second codebook group,
- wherein the transmission of the data includes generation of a codeword of the at least one layer based on the data associated with the at least one layer.

A method, comprising:
- allocating at least one layer of a plurality of layers to a terminal device;
- changing, based on a change in traffic, a number of layers of the plurality of layers,
- wherein the plurality of layers are subjected to a non-orthogonal multiplexing operation based on a codebook;
- acquiring information that indicates the at least one layer of the plurality of layers is allocated to the terminal device;
- selecting one of a first codebook group of a plurality of codebook groups or a second codebook group of the plurality of codebook groups based on a first number of layers of the first codebook group and a second number of layers of the second codebook group,
- wherein the second number of layers is smaller than the first number of layers;
- transmitting the at least one layer and the selected one of the first codebook group or the second codebook group, to the terminal device;
- and
- transmitting data associated with the at least one layer based on the selected one of the first codebook group or the second codebook group,
- wherein the transmission of the data includes generation of a codeword of the at least one layer based on the data associated with the at least one layer.
