Figure 7-6 RHUB-pRRU star topology
Figure 7-7 RHUB-pRRU load sharing topology
Configuration principles for the RHUB-pRRU load sharing topology are as follows:
l
Load sharing cannot be realized over the optical ports on pRRUs.
l
A pRRU cannot connect to two RHUBs at the same time.
l
Extenders are optional. If used, an extender must be used for both Ethernet cables
between an RHUB and a pRRU and the length difference between the two Ethernet
cables cannot exceed 10 m.
l
An RHUB can connect to up to four pRRUs. Data of a cell does not support load sharing
over two Ethernet ports.
Figure 7-8 RHUB-pRRU dual-star topology
Configuration principles for the RHUB-pRRU dual-star topology are as follows:
l
Only Wi-Fi-capable pRRU3911s support the dual-star topology.
l
A pRRU must use the CPRI_E0 port (for power supply and CPRI signal transmission)
and the GE port (for Wi-Fi signal transmission).
l
A pRRU connects to an RHUB over the CPRI_E0 port and to a common Ethernet device
over the GE port.

7.1.2.2 BBU-DCU Networking Configurations
This section describes the BBU-DCU networking configuration principles in BBU+DCU
mode.
l
Only one BBU is allowed to connect to a DCU to avoid clock inconsistency.
l
The BBU is connected only to the even-numbered optical ports (ports 0, 2, 4, 6, 8, and
10) on the DCU and must be first connected to port 0 or 2, from which clock signals of
the DCU are recovered. The length difference of optical fibers between the DCU and the
BBU must be less than 30 m to ensure delay alignment of the baseband data from the
BBU to the DCU.
l
The BBU is connected only to the even-numbered optical ports (ports 0, 2, 4, 6, 8, and
10) on the DCU, while the RHUB is connected only to the odd-numbered optical ports
(ports 1, 3, 5, 7, 9, and 11) on the DCU. CPRI ports on the DCU must be used in the
following pairs: CPRI0/CPRI1, CPRI2/CPRI3, CPRI4/CPRI5, CPRI6/CPRI7, CPRI8/
CPRI9, and CPRI10/CPRI11. Even-numbered optical ports are used for signal input, and
odd-numbered optical ports are used for signal output. BBU baseband data exchange
over optical ports on the DCU is not required.
l
The main control board of the BBU must be configured in slot 6. The rate of the optical
link between the DCU and the BBU must be 10.1 Gbit/s or 9.8 Gbit/s, instead of being
auto-negotiated. The BBU cannot work in load sharing mode.
l
The total input power of RFC ports on the DCU must not exceed 20 dBm. If the RRU
serves as the signal source (the recommended RRU output power is at least 5 W), use a
20–30 dB attenuator or coupler based on the RRU transmit power. Do not connect the
RRU to the RFC port directly. Otherwise, the RFC will be damaged.
l
The transition band configured on the DCU must be 800 kHz for the GSM/CDMA
subband.
l
Only one subband can be scheduled in an RHUB.
l
Configured GSM TRXs cannot be contiguous.
l
All pRRUs on an optical link must connect to the RHUB through either a single Ethernet
cable or two Ethernet cables.
l
In BBU+DCU dual-Ethernet cable networking, the pRRU connects to the RHUB over
the following port pairs on the RHUB: 0/1, 2/3, 4/5, and 6/7. On the pRRU, port

Configuration Principle
7 Networking Configurations
Configuration principles for the RHUB-pRRU load sharing topology are as follows:
l
Load sharing cannot be realized over the optical ports on pRRUs.
l
A pRRU cannot connect to two RHUBs at the same time.
l
Extenders are optional. If used, an extender must be used for both Ethernet cables
between an RHUB and a pRRU and the length difference between the two Ethernet
cables cannot exceed 10 m.
l
An RHUB can connect to up to four pRRUs. Data of a cell does not support load sharing
over two Ethernet ports.
Figure 7-15 RHUB-pRRU dual-star topology
Configuration principles for the RHUB-pRRU dual-star topology are as follows:
l
Only Wi-Fi-capable pRRU3911s support the dual-star topology.
l
A pRRU must use the CPRI_E0 port (for power supply and CPRI signal transmission)
and the GE port (for Wi-Fi signal transmission).
l
A pRRU connects to an RHUB over the CPRI_E0 port and to a common Ethernet device
over the GE port.

7.1.3.3 RHUB-pRRU Networking Configurations
This section describes the RHUB-pRRU networking configuration principles in BBU+MERC
mode.
The star, load sharing, and dual-star topologies are supported between the RHUB and the
pRRU. (Wi-Fi is supported in dual-star topology only for international market.)
Figure 7-20 RHUB-pRRU star topology
Figure 7-21 RHUB-pRRU load sharing topology
Configuration principles for the RHUB-pRRU load sharing topology are as follows:
l
Load sharing cannot be realized over the optical ports on pRRUs.
l
A pRRU cannot connect to two RHUBs at the same time.
l
Extenders are optional. If used, an extender must be used for both Ethernet cables
between an RHUB and a pRRU and the length difference between the two Ethernet
cables cannot exceed 10 m.
l
An RHUB can connect to up to four pRRUs. Data of a cell does not support load sharing
over two Ethernet ports.

7.1.4 Macro-LampSite Co-BBU
This section describes macro-LampSite co-BBU configuration principles, including general
restrictions, RRU quantity specifications, and cell specifications.
NOTE
l In macro-LampSite co-BBU networking, macro RRUs and LampSite pRRUs/vRRUs share a BBU
subrack. Macro RRUs can be DAS macro RRUs, outdoor macro RRUs, or Book RRUs.
l By default, macro-LampSite co-BBU is not supported. If it is required, contact Huawei engineers for
application.
7.1.4.1 General Restrictions
This section describes general restrictions in macro-LampSite co-BBU scenarios.
Based on the configuration principles of macro base stations, this section describes the BBU
in the LampSite solution and its application differences. For details about BBU configuration
principles, typical configurations, and version upgrades, see 3900 Series BBU Hardware
Description and BBU5900 Hardware Description.

l
In SRAN12.0 or earlier, DAS macro RRUs, outdoor macro RRUs, and LampSite pRRUs
share a BBU subrack. In SRAN12.1 or later, DAS macro RRUs, outdoor macro RRUs,
Book RRUs, and LampSite pRRUs/vRRUs share a BBU subrack.
l
Macro-LampSite co-BBU applies to the LTE only, UL, and GUL modes. The LampSite
solution does not support BBU access in GSM mode. In macro-LampSite co-BBU
networking, the base station type must be macro.
l
Macro and LampSite base stations share the BBU but not the baseband processing unit
or CPRI link.
l
In LTE FDD macro+LTE FDD/UMTS LampSite networking, the MBTS must be used.
In the separate-MPT scenario, if LTE FDD macro needs to be upgraded, both LTE FDD
macro and MBTS must be upgraded. Such a restriction also applies to the LampSite only
scenario. This is because separate upgrade in the separate-MPT scenario is not supported
when Ethernet cables are shared among GSM, UMTS, and LTE and 4:1 CPRI
compression is used.
l
Main control boards and baseband processing units that are applicable to both macro and
LampSite base stations are used for UMTS and LTE. Main control boards and baseband
processing units that are applicable only to macro base stations are used for GSM.
l
In macro-LampSite co-BBU networking, BBU cascading is not supported.

7.1.5.1 General Restrictions
This section describes general restrictions in macro-LampSite co-cell scenarios.
In SRAN12.1 or later, LTE FDD macro-LampSite co-cell is supported where DAS macro
RRUs and Book RRUs can be deployed with LampSite pRRUs/vRRUs or pRRU/vRRU
groups to serve SFN cells.
Macro-LampSite co-cell in LTE FDD is subject to the following general restrictions:
l
Requirements described in 7.1.4.1 General Restrictions must be met.
l
When 1T1R/2T2R DAS macro RRUs are deployed with LampSite pRRUs/vRRUs to
serve SFN cells, there are no constraints on DAS macro RRU and LampSite pRRU/
vRRU models. 1T2R/2T4R/4T/8T DAS macro RRUs cannot be deployed with LampSite
pRRUs/vRRUs to serve SFN cells.
l
Two 1T1R DAS macro RRUs can be combined to serve one 2T2R physical cell. Two
2T2R pRRUs/vRRUs and DAS macro RRUs cannot be combined to serve one 4T4R
physical cell.
l
The cell bandwidth can be 5 MHz, 10 MHz, 15 MHz, or 20 MHz.
l
BS-DIY, configuration express, automatic topology configuration, or automatic cell
configuration is not supported.
l
The power can be different and separately configured for the macro and LampSite
physical cells. The power cannot be adjusted for pRRUs/vRRUs serving the same
physical cell, that is, pRRUs/vRRUs involved in RF combination can only be configured
with the same power.
l
The baseband processing units applicable to macro-LampSite co-cell are those applicable
to macro-LampSite co-BBU.
7.1.5.2 Configuration Restrictions

NOTE
In the Slot Assignment column, the leftmost slot has the highest priority.
It is recommended that the LTE baseband processing unit converge data and provide optical fiber
connections for data transmission.
If the BBU3910 works in separate-MPT mode, only the board in slot 2 or 3 can provide optical fiber
connections in SRAN11.1 and earlier versions.
If the BBU3910 works in separate-MPT mode, only boards in slots 2 and 3 can provide optical fiber
connections in SRAN12.0 and later versions.
The CPRI networking principles for LTE NB-IoT are the same as those for LTE FDD.
For China Unicom with pRRU3912s/5000 series pRRU modules used in the UL separate-MPT scenario,
the following restrictions apply if SRAN12.1 or a later version is not used for UMTS:
l
The RHUB must be connected to the UMTS baseband processing unit over optical fiber
connections.
l
The maximum BBU-RHUB distance must not exceed 6 km.
l
pRRU3912s/5000 series pRRU modules and pRRU3902s/pRRU3911s cannot be connected to the
same BBU.

Board Configuration Principles
Main control board:
l
The UMPTb supports UMTS/LTE FDD/LTE TDD/LTE NB-IoT/RFA. LTE FDD and
LTE TDD must share the main control board. UMTS and LTE can use the same or
different main control boards. When MERC-based input is used, only co-MPT is
supported.
l
The UMPTe supports UMTS/LTE FDD/LTE TDD/LTE NB-IoT/RFA. LTE FDD and
LTE TDD must share the main control board. UMTS and LTE can use the same or
different main control boards. When MERC-based input is used, only co-MPT is
supported.
l
When UMTS and LTE share the baseband processing unit, they must also share the main
control board.
Baseband processing unit:
l
The model and number of baseband processing units need to be configured according to
the network plan based on the supported modes and specifications. A single BBU
subrack can be configured with up to six baseband processing units.
l
LTE FDD and LTE TDD cannot share the baseband processing unit.
MERC:
l
For Chinese market, the BBU equipped with the MERC supports CDMA in RF input
mode in SRAN12.1 and later versions. For international market, the BBU equipped with
the MERC supports GSM/CDMA/UMTS in RF input mode in SRAN13.1 and later
versions.
l
Only the BBU3910 and later BBU subracks can be configured with the MERC.
l
One MERC supports only one frequency band. A single BBU can house up to five
MERCs.
l
The MERC does not have CPRI ports and therefore cannot be connected to RF modules
through optical fibers. Instead, optical fibers must be routed from the baseband
processing unit to transmit data forwarded by the backplane.

NOTE
The full-load input power per MERC port ranges from 0 dBm to 16 dBm or is converted into the input
pilot power using the following formula: Pilot power = Full-load power – Pilot power ratio. The pilot
power ratio for each mode is calculated as follows:
l
The pilot power ratio in GSM mode depends on the number of TRXs which is calculated as
follows: 10 x lg(1/TRX quantity) dB.
l
The pilot power ratio in UMTS mode depends on the power configuration of channels such as the
Common Pilot Channel (CPICH), synchronization channel (SCH), and broadcast channel (BCH).
For example, if the CPICH has a 10% power ratio, the pilot power ratio is –7.4 dB.
When multiple carriers share one port, the full-load power of each carrier must be at least –6 dBm and
the difference between the total power of the port and the full-load power of each carrier must be 12 dB
or less.

MERC Configuration Principles
l
The MERC must be used with the UMPTb/UBBPd or later main control boards/
baseband processing units.
l
The MERC enables RFA which cannot be deployed alone and must be deployed with
UMTS/LTE in co-MPT mode.
l
An MERC working on any frequency band supports up to three 2T2R or six 1T1R RF
signal inputs.
l
The total input power of MERCs port in the BBU must not exceed 20 dBm. If the RRU
serves as the signal source (the recommended RRU output power is at least 5 W), use a
20–30 dB attenuator or coupler based on the RRU transmit power. Do not connect the
RRU to the MERC port directly. Otherwise, the MERC will be damaged.
l
An MERC provides six 1T1R RF ports, with up to eight subbands per port. An MERC
supports up to 24 1T1R or 12 2T2R subbands.
NOTE
In LTE MIMO scenarios, two consecutive 1T1R ports (for example 0–1, 2–3, 4–5) work as a
group of MIMO RF ports.

–
New deployment: A BBU3910 contains one UPEUd by default, which supports 650
W power supply. If 1000 W power supply or power backup (less than or equal to
650 W) is required, a second UPEUd needs to be configured.
–
Capacity expansion for inventory deployment: Circuit breakers in the existing
cabinets need to be reconfigured. In this case, the power capacity (≥ 20 A) of circuit
breakers needs to be considered.

Configuration Principle
l
3000 series pRRU modules support MERC-based input in SRAN13.1 but not in
SRAN12.1.
l
5000 series pRRU modules and 3000 series pRRU modules cannot serve the same cell
through RF combination. In the BBU access scenario, they cannot serve the same
physical cell through RF combination. In the MERC-based input scenario, they cannot
share the subband.

9.2 Spare Parts Configurations
This section describes the principles for configuring the spare parts.
9.3 Precautions
This section provides precautions on spare parts configuration.
9.1 Spare Parts List
This section provides the spare parts list.
The spare parts of LampSite base stations are classified into commissioning spare parts (such
as BBU boards and RF modules) and non-commissioning spare parts (such as cables, fans,
and optical modules).
You can visit http://support.huawei.com to obtain the spare parts catalogs for corresponding
base stations.
9.2 Spare Parts Configurations
This section describes the principles for configuring the spare parts.
The Poisson algorithm (recommended) and percentage algorithm apply in configuring the
spare parts.
l
Use the Poisson algorithm, unless otherwise required by the customer. The following
describes the Poisson algorithm which has been integrated into the Configurator, and
thereby does not need to be manually calculated by product managers.
Poisson algorithm: Use this formula to obtain the value of x which indicates the number
of spare parts.

P indicates the board damage probability accepted by customers, namely the service
level. Usually, the following applies: 85% ≤ P(x) < 100%.
е = 2.71828183
λ = Network capacity x Annual board failure rate x Replenishment period/365
–
Replenishment period: 60 days usually
–
Network capacity = Number of boards in the main equipment
Network capacity of board 02319428 = 1000
–
Board annual failure rate: Provided by the spare parts center. Each board has its
own annual failure rate.
Given that the annual failure rate of board 02319428 is 0.005000, then:
λ = 1000 x 0.005000 x 60/365 = 0.8219178
According to the Poisson algorithm, the number of spare parts for board 02319428
is 4.
l
If the customer has requirements on the percentage of spare parts, use the percentage
algorithm to calculate the number of spare parts.
9.3 Precautions
This section provides precautions on spare parts configuration.
The spare parts quantity calculated using the Poisson algorithm can meet only the basic
requirement for live networks. If a customer requires Huawei to comply with a specified SLA,
persuade the customer to purchase the spare parts management service (SPMS) of Huawei.
