NOTE
● In the AAU Configuration Combination column containing xA+yP, A indicates the
active module and P indicates the passive module that is not installed in the AAU slot. x
and y indicate the frequency bands of active and passive modules, respectively. For
example, 2100 MHz A+700-900 MHz P means that the frequency band of the active
module is 2100 MHz and that of the passive module ranges from 700 MHz to 900 MHz.
● In the RU Configuration column, UP indicates that the RU is installed in the upper slot
of the AAU and DOWN indicates that the RU is installed in the lower slot of the AAU.
● In the Antenna Configuration column, UP indicates the frequency band supported by
the antenna port connected to the RU in the upper slot at the rear of the antenna,
DOWN indicates the frequency band supported by the antenna port connected to the
RU in the lower slot at the rear of the antenna, and BOTTOM indicates the frequency
band supported by the antenna port located at the bottom of the antenna and
connected to a passive RF module.
● If a combiner is configured, the insertion loss caused by the combiner must be
considered when the passive module is connected to the combiner. Therefore, the gain
of a passive module on the antenna side equals the antenna gain minus 0.5 dB. For
example, with the configuration of 2100 A (2T4R 2x60 W)+1800 P (4 ports)+700-900 P
(2 ports), if a combiner is connected to an RF module working on the 1800 MHz
frequency band, the gain of the RF module on the antenna side is 16.5 dBi (= 17 dBi –
0.5 dB).

transmit channels and B receive channels.
b: The bandwidth information in Supported Bandwidth is the standard
bandwidth that can be configured for a single-mode carrier when only one
carrier is configured. In any carrier combination scenario, the total bandwidth of
all carriers cannot exceed the IBW value. For details about the bandwidth that

● The Typical Power Configuration Reference for AAU Modules document includes the
configurable carrier combinations and the output power of each carrier in each
combination. Before referring to this document, you must be familiar with the output
power configuration rules. For details, see 18 Power Configuration Rules for RF
Modules.
● Each Output Power per Carrier (W) value in the Typical Power Configuration
Reference for AAU Modules document indicates the maximum output power of each
carrier under the corresponding configuration while ensuring the network performance.
The actually configured carrier power of RF modules can be less than or equal to the
value of Output Power per Carrier (W) in the document. The power configuration that
is not supported in the document may be configurable on the software. Huawei can
only promise the performance with the power configurations listed in the document.

18 Power Configuration Rules for RF Modules
Power Configuration Rules for RF
Modules
This section describes the power configuration standards for RF modules, RF
channel configuration rules, and remarks.
RF Compliance Standards
When you configure power for RF modules, comply with the following standards:
●
GSM: multi-carrier base transceiver station (MCBTS) in 3GPP TS 45.005
●
UMTS: 3GPP TS 25.141
●
LTE: 3GPP TS 36.141
●
NR TDD: 3GPP TS 38.104
●
Multimode: multi-standard radio (MSR) in 3GPP TS 37.141
RF Channel Configuration Rules
When multimode RF modules work in a single mode, the rules for configuring RF
channels are the same as those for configuring RF channels in single-mode RF
modules. The following table provides the rules for configuring RF channels in
multimode RF modules working in multiple modes.
Table 18-1 Rules for configuring RF channels in multimode RF modules
RF
Module
Type
RF Channel Configuration Rule
1T RF
module
Non-MSR standard: One RF module can serve only one RAT and the
rules for configuring RF channels in such an RF module is the same
as those for configuring RF channels in a single-mode RF module.
MSR standard: One RF module can serve two RATs at the same time,
and the two RATs can be carried over the same transmit channel.

Module
Type
RF Channel Configuration Rule
2T RF
module
Non-MSR standard: Multiple RATs cannot be configured on one RF
channel. For example, GSM carriers are carried over TX channel A
while UMTS carriers are carried over TX channel B.
MSR standard: One RF channel can be configured with two RATs.
Power of two transmit channels must be balanced if possible.
NOTE
1T RF module: module that has only one transmit channel. 2T RF module: module that has two
transmit channels.
NR Configuration Rules
To ensure the performance of an NR cell in low frequency bands, the minimum
configurable output power of the NR cell is equal to the total rated power of an
RF module (unit: W) divided by 10. To ensure the performance of an NR cell in
high frequency bands, the minimum configurable EIRP of an RF module is equal
to the rated EIRP of the RF module (unit: dBm) minus 10.
NOTE
The AAU5612 is used as an example. The maximum output power of the AAU5612 is 200 W.
When you configure an NR cell, the minimum output power of the NR cell is 20 W (equal to
200 W divided by 10).
●
●
In this document, a transmit channel is represented by PA. For example, n
transmit channels of an RF module are represented by PA1, PA2, ..., and PAn.
The two transmit channels of a 2T RF module are represented by PA1 and
PA2. Unless otherwise specified, the power configuration values of all PAs of
an RF module can be interchanged.
In this document, each value in the Output Power per Carrier (W) column
indicates the maximum output power of each carrier under the corresponding
configuration while ensuring the network performance. Output Power per
GSM Carrier With Dynamic Power Sharing is the available maximum
output power for every carrier during dynamic power sharing. If this power is
exceeded, the system cannot guarantee the network performance and will
report an alarm.
NOTE
● The actually configured carrier power of RF modules can be less than or equal to the
value in the Output Power per Carrier (W) column in this document.
● The specifications that are not supported in this document may be configurable. Only
the performance with the configuration within the committed specification scope is
ensured.
●
●
In MIMO carrier scenarios, MxN W indicates that an MIMO carrier is
configured in M PAs, and each PA is configured with power of N W.
For an nT RF module (n is 2, 4, or 8), the restriction is as follows:

channel i; Pi indicates the output power of each carrier of transmit channel i;
PAt indicates the total number of carriers configured in this RF module; P
indicates the maximum output power supported by each carrier.
●
A requirement for the GU frequency spacing is as follows: GU frequency
spacing ≥ [(GSM bandwidth/2) + (UMTS bandwidth/2)].
●
The typical configuration tables for PAs of GSM RF modules provided in this
document only list power values in GMSK mode because power values in
8PSK mode cannot be configured.
●
For the GBTS and eGBTS, the output power per carrier of the same RF module
is the same. For GBTSs, the unit of the output power per carrier is W. For
eGBTSs, the unit of the output power per carrier is dBm. The conversion
relationship is as follows: dBm = 10 x log (1000 x W, 10) For example, when
there is only one carrier on an AAU (GSM, 1900 MHz), the output power per
carrier for a GBTS is 60 W (GMSK), and that for an eGBTS is 47.8 dBm
(GMSK) which is the result of ROUND(10 x log (1000 x 60, 10)).
●
The formulas for calculating the minimum NB-IoT power per PA for an RF
module are as follows:
–
Minimum NB-IoT power per PA for an RF module when NB-IoT cells work
in guardband or in-band mode = Total rated power per PA/10000
–
Minimum NB-IoT power per PA for an RF module when NB-IoT cells work
in standalone mode = Total rated power per PA/100
NOTE
For example, an AAU3920 supports a maximum output power configuration of 2x80 W.
The minimum NB-IoT power per PA for an AAU3920 when NB-IoT cells work in standalone
mode is calculated as follows: Minimum NB-IoT power per PA for an AAU3920 = 80 W/100
= 0.8 W.
●
Issue 02 (2020-07-27)
When two LTE NB-IoT carriers are configured, the bandwidth spacing
between the two NB-IoT carriers cannot be greater than 300 kHz.
