Abstract
A method of selecting a codebook is disclosed. The method is performed in a network node and includes: determining whether to use single-user multiple-input-multiple output, SU-MIMO, or multi-user multiple-input-multiple output, MU-MIMO, in a cell (C1) controlled by the network node, and selecting, based on the determining, a first codebook or a second codebook for use in communication with a communication device within the cell (C1). The first codebook is configured for SU-MIMO communication and the second codebook is configured for MU-MIMO communication. A network node, computer program and computer program product are also disclosed.
Claims21
A method of selecting a codebook, the method being performed in a network node, the method comprising:
- determining whether to use one of single-user multiple-input-multiple output, SU-MIMO, and multi-user multiple-input-multiple output, MU-MIMO, in a cell (C1) controlled by the network node;
- and
- selecting, based on the determining, one of a first codebook and a second codebook for use in communication with a communication device within the cell (C1), the first codebook being configured for SU-MIMO communication and the second codebook being configured for MU-MIMO communication.
A computer storage medium storing an executable computer program for a network node for selecting a codebook, the computer program comprising computer program code, which, when executed on at least one processor on the network node causes the network node to:
- determine whether to use one of single-user multiple-input-multiple output, SU-MIMO, and multi-user multiple-input-multiple output, MU-MIMO, in a cell (C1) controlled by the network node;
- and
- selecting, based on the determining, one of a first codebook and a second codebook for use in communication with a communication device within the cell (C1), the first codebook being configured for SU-MIMO communication and the second codebook being configured for MU-MIMO communication.
(canceled)
A network node for selecting a codebook, the network node being configured to:
- determine whether to use one of single-user multiple-input-multiple output, SU-MIMO, and multi-user multiple-input-multiple output, MU-MIMO, in a cell (C1) controlled by the network node;
- and
- select, based on the determining, one of a first codebook and a second codebook for use in communication with a communication device within the cell (C1), the first codebook being configured for SU-MIMO communication and the second codebook being configured for MU-MIMO communication.
