Fig. 2-74: Beamforming settings for TM8, 2 layers
Beamforming Mode ← Beamforming Model
Enables or disables beamforming.
●
Off
: Beamforming is disabled
●
On
: Beamforming is enabled. The configured beamforming matrix is used.
●
TS 36.521 Beamforming Mode
:
Beamforming is enabled. The beamforming matrix is selected randomly as defined
in 3GPP TS 36.521, Annex B.4.1 and B.4.2.
This value is not allowed for 1x1 beamforming matrices.
Remote command:
Number of Layers ← Beamforming Model
Transmission mode 7 uses only a single transmission layer. For transmission mode 8,
you can select between one layer (single-layer beamforming) and two layers (dual-
layer beamforming).
Remote command:
Beamforming Matrix ← Beamforming Model
This section defines the beamforming matrix for the beamforming mode "On".
The matrix characterizes the mapping of the UE-specific antenna ports 5, 7 and 8 to
the transmit antennas, see
chapter 2.2.11.2, "Beamforming Matrix"
Each element of the matrix is a complex number, defined via its phase and its magni-
tude. The size of the matrix depends on the scenario, the transmission mode and the
number of layers.
●
1x1 matrix (h

):
You can configure the phase of the coefficient.
●
1x2 matrix (h
11
and h
21
):
You can configure the phase of both coefficients.
●
2x2 matrix (h
11
to h
22
):
