1.2.5 AAU RET System
Massive MIMO modules adjust the tilt of antenna beams by modifying phase weights of RF
channels.
RET Function
Massive MIMO modules are 64T64R AAUs, and each antenna array has four independent RF
channels. The antenna beam tilt can be adjusted by changing the phase weights K1, K2, K3,
and K4 of the four RF channels.
Figure 1-4 shows the working principle of the RET system of a Massive MIMO module.

l
Run the MOD NRDUCELLTRPBEAM (NR) or MOD BFANT (LTE) command.
–
Set the downtilt using the Tilt parameter.
–
Set parameters such as the tilt, horizontal beamwidth, and vertical beamwidth of
broadcast beams using the Coverage Scenario parameter to adjust the broadcast
beam form.
n
Broadcast beamforming enables the base station to apply weighting on
broadcast beams to adjust the coverage scope of such beams.
n
The weighting designed for typical coverage scenarios has been written into
the antenna weight file.
The product software adjusts the antenna downtilt and other parameters
according to the values of K1, K2, K3, and K4. The values of K1, K2, K3, and
K4 are generated based on Tilt and Coverage Scenario parameters.
l
If the existing coverage scenarios do not meet the requirements, contact Huawei
technical support.
NOTE
For details on the Massive MIMO service coverage solutions and engineering guidelines, see Beam
Management Feature Parameter Description or Massive MIMO Feature Parameter Description.
1.2.6 Optical Modules
An optical module transmits optical signals between an optical port and an optical fiber.

The transmission mode is displayed as "SM" on the label of a single-mode optical
module and "MM" on the label of a multimode optical module.
Optical modules must be used in pairs on both ends of an optical fiber. The following table
describes the mapping.
Each type of optical module has its own mapping. If different types of optical modules are
used, performance risks may arise, for example, alarms, bit errors, and interrupted links.
