Technical Description
5 Physical Devices
5.1 BBU
The BBU is a baseband processing unit and centrally manages the entire base station.
The BBU provides the following functions:
l
Manages the entire base station system in terms of operation, maintenance, signaling
processing, and system clock.
l
Processes uplink and downlink data, and provides common public radio interfaces
(CPRIs) for the communication between the BBU and RF modules.
l
Provides physical ports for information exchange between the base station and the
transport network.
l
Provides an OMCH between the base station and the operation and maintenance center
(OMC).
l
Provides ports for receiving and transmitting signals from environment monitoring
devices.
BBUs fall into two types: BBU3900 and BBU3910. With a case structure, BBUs can house
different types of boards and modules. For details about ports, indicators, DIP switches,
configuration principles, and functions of boards and modules, see BBU Hardware
Description by choosing 3900 Series Base Station Product Documentation > Description >
Hardware Description. For technical specifications of a BBU, see 8.1 BBU Technical
Specifications.
NOTE
Unless otherwise specified, the BBU refers to both the BBU3900 and BBU3910 in this document.
5.2 DCU
In the downlink, the DCU converts the GSM RF signals into baseband signals through downconversion and digital sampling, performs CPRI MUX for GSM baseband signals, and then
sends the signals to the RHUBs over CPRI ports. The uplink flow is the reverse of the
downlink flow.
The DCU provides the following functions:
l
Provides physical ports for information exchange between base stations and the transport
network.
l
Provides CPRI ports for communication with RHUBs.
l

5.3 RHUB
The RHUB is a remote CPRI data convergence unit. It supports the communication between
the BBU and pRRUs and between the BBU and RRUs. The RHUB provides the following
functions:
l
Receives downlink baseband signals from the BBU, splits these signals, and transmits
them to pRRUs or RRUs.
l
Receives uplink baseband signals from pRRUs or RRUs, combines these signals, and
transmits them to the BBU.
l
Supplies power to pRRUs or RRUs using the built-in Power over Ethernet (PoE)
technology.
For details about the appearance, ports, and indicators of an RHUB, see DBS3900 LampSite
Hardware Description by choosing 3900 Series Base Station Product Documentation >
Description > Hardware Description. For technical specifications of an RHUB, see 8.3
RHUB Technical Specifications.
5.4 pRRU
The pRRU works as a pico remote radio unit to process RF signals.
The pRRU transmits CPRI data using Ethernet cables. The main functions of the pRRU are as
follows:
l
The transmit channel receives the baseband signals from the BBU and performs digitalto-analog conversion. The baseband signals are up-converted to the transmit frequency
band using the zero intermediate frequency (IF) technology. The pRRU then filters and
amplifies the signals, which are sent to the antenna for transmission.
l
The receive channel receives the RF signals from the antenna. Then, the RF signals are
down-converted to baseband signals using the zero IF technology and sent to the BBU
for processing after being filtered and amplified.
l
The pRRU supports internal or external antennas.
l
The pRRU supports PoE as the power supply.
l
RF daughter boards in different modes can be configured to achieve flexible multimode
configurations.
l
One UMTS+LTE capable RF daughter board on the pRRU can be used in refarming for
mode evolution and deployment cost reduction.
For details about the appearance, ports, and indicators of a pRRU, see DBS3900 LampSite
Hardware Description by choosing 3900 Series Base Station Product Documentation >
Description > Hardware Description. For technical specifications of a pRRU, see 8.4
pRRU Technical Specifications.
NOTE
l Unless otherwise specified, the pRRU refers to the pRRU3901, pRRU3902, pRRU3907, pRRU3911, and
pRRU3916 in this document.
l The pRRU3902 is classified into pRRU3902 with internal antennas and pRRU3902 using external
antennas. The pRRU3902 using external antennas has no internal antennas and must connect to external
antennas to work properly.

5.5 RRU
The RRU works as a lower-power remote radio unit to process RF signals. RRUs include the
RRU3230E and RRU3936E. The RRU provides the following functions:
l
Receives downlink baseband data from the BBU and sends uplink baseband data to the
BBU.
l
Receives RF signals from the antenna, down-converts the signals to IF signals, amplifies
the IF signals, and performs analog-to-digital conversion. Filters downlink signals,
performs digital-to-analog conversion, and up-converts RF signals to the transmit (TX)
band, on the TX channel.
l
Multiplexes receive (RX) and TX signals on the RF channel to enable these signals to
share the same antenna path, and filters RX and TX signals.
For details about the appearance, ports, and indicators of an RRU, see RRU3230E Hardware
Description and RRU3936E Hardware Description. For technical specifications of an RRU,
see 8.5 RRU Technical Specifications.
5.6 Wi-Fi
The DBS3900 LampSite provides Wi-Fi services if the pRRUs are equipped with Wi-Fi
daughter boards, which connect to WLAN networks through GE ports.

NOTE
l In UMTS+LTE, GSM DCU+UMTS, and GSM DCU+LTE modes, the pRRU can connect to the RHUB
through one Ethernet cable to carry the CPRI data. Therefore, one RHUB can connect to a maximum of
eight pRRUs. For details about Ethernet cable configurations, see Table 6-2 and Table 6-3.
l In UMTS mode, the WBBPf or UBBPd board can be used. In LTE mode, the LBBPd or UBBPd board
can be used. The UBBPd board is recommended.
l The UBBPd board is recommended to be used as a single-mode baseband processing unit, not multimode baseband processing unit.
l Combination indicates combination of pRRU cells.
l For details about the DCU, see DBS3900 IBS Product Description by choosing Support > Product
Support > Wireless Network > Small Cell > Small Cell > SingleDAS > DBS3900 IBS at http://
support.huawei.com.
Ethernet Cable Configuration for pRRUs
If the physical bandwidth of a CPRI port is inadequate to provide bandwidth required by cells
established by a pRRU, the branch load sharing topology can be used. In this topology, a
pRRU connects to the same RHUB over two Ethernet cables.
The integrated Wi-Fi module on a pRRU is not connected to any RHUB but directly
connected to a WLAN over an Ethernet cable.
Table 6-2 describes the Ethernet cable configurations for a pRRU3901, pRRU3907, or
pRRU3911 working in UMTS, LTE, or UMTS+LTE mode.
NOTE
l Only one Ethernet cable needs to be provided for a pRRU3902 to transmit CPRI signals.
l For a pRRU3911 enabled with the Wi-Fi function, only one Ethernet cable can be used to transmit CPRI
signals.

in slots 2 and 3 of the BBU, respectively.
For example, if one WBBPf/UBBPd (UMTS)
board is configured in slot 2, one LBBPd/
UBBPd (LTE) board must be configured in slot
3; if one LBBPd/UBBPd (LTE) board is
configured in slot 3, one WBBPf/UBBPd

baseband processing unit of one mode, either
WBBPf/UBBPd (UMTS) or LBBPd/UBBPd
(LTE), can provide the CPRI port. A single
BBU can provide six UMTS+LTE FDD dualmode CPRI ports at most.
l If the BBU3910 works in dual mode, the
baseband processing units in slots 2 and 3 can
provide CPRI ports. In separate-MPT
scenarios, the baseband processing units
providing CPRI ports must work in the same
mode, and the UBBPd for UMTS only and
UBBPd for LTE only can be used. In co-MPT
scenarios, the UBBPd for UMTS only, UBBPd
for LTE only, and UBBPd for UMTS/LTE can
be used to provide CPRI ports. A single BBU
can provide 12 UMTS+LTE FDD dual-mode
CPRI ports at most.
l If the BBU is configured with different
baseband processing units, the UBBPd board
preferentially provides the CPRI port.

CPRIEX parameter in the MOD BBP or LST BBP command. Only the CPRI0, CPRI1, and CPRI2
ports on the LBBPd can be used when the CPRI extension switch is turned on.
l The CPRI port rates 1.25 Gbit/s and 2.5 Gbit/s are not recommended, for the transmission bandwidth
is limited.
l Only the LBBPd board in the separate-MPT scenario supports AxC expansion.

l The LTE receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 5 MHz channel
bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.
l The 11 configuration indicates that two continuous carriers are configured and the spacing between the
center frequencies of two neighboring carriers is 5 MHz. In 101 or 1001 configuration, discontinuous
carriers are configured. The value 0 indicates the spacing of 5 MHz. For example, the 1001 configuration
indicates that two discontinuous carriers are configured and the spacing between the center frequencies of
the two carriers is 15 MHz.
l When the DCU is used in GSM DCU+UMTS networking scenarios, the GSM mode does not involve
receiver sensitivity.

l A single-band pRRU can work in GSM+LTE mode only on the 1.8 GHz band and in UMTS+LTE mode
on the 850 MHz, 900 MHz, 2.1 GHz, AWS, or PCS band.
l A pRRU3911 can work in two or three different frequency bands in any modes. A pRRU3911 can work
in LTE FDD+LTE TDD mode in SRAN11.1 and later versions.
l When working in the same frequency band and in the same mode, the pRRU3901 and pRRU3911 can be
used together in the same networking.
l When working in the same frequency band and in the same mode, the pRRU3902 and pRRU3911 can be
used together in the same networking.
l FCA transparent transmission is supported by the pRRU3911.
l The pRRU3902 (2.1 GHz UMTS) and pRRU3911 (1.8 GHz LTE FDD+2.1 GHz UMTS+2.6 GHz LTE
FDD) can be used together in the same networking.
l The pRRU3911 cannot work in Wi-Fi only mode.
l The pRRU3911 supports Wi-Fi services in the following scenarios: 900 MHz GSM DCU+1.8 GHz LTE

Technical Specifications.
l A pRRU3911 only supports one band for UMTS. However, if a pRRU3911 can work at both 900 MHz
and 2.1 GHz, either band can accommodate a UMTS carrier.
Table 8-50 lists other RF specifications of a pRRU3911.
NOTE
l ATBR in the RX and TX Channels column indicates that the RF module has A transmit channels and B
receive channels.
l CxD in the Maximum Output Power column indicates that this RF module has C TX channels and the
maximum output power for each TX channel is D mW.
l Maximum output power = Maximum output power of the PA - Internal loss. The maximum output power
is measured at the antenna port.
l The LTE receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 5 MHz channel
bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.
l The 11 configuration indicates that two continuous carriers are configured and the spacing between the
center frequencies of two neighboring carriers is 5 MHz. In 101 or 1001 configuration, discontinuous
carriers are configured. The value 0 indicates the spacing of 5 MHz. For example, the 1001 configuration
indicates that two discontinuous carriers are configured and the spacing between the center frequencies of
the two carriers is 15 MHz.
l When the DCU is used in GSM DCU+UMTS/GSM DCU+LTE FDD/GSM DCU+UMTS+LTE FDD
networking scenarios, the GSM mode does not involve receiver sensitivity.

l ATBR in the RX and TX Channels column indicates that the RF module has A transmit channels and B
receive channels.
l CxD in the Maximum Output Power column indicates that this RF module has C TX channels and the
maximum output power for each TX channel is D mW.
l Maximum output power = Maximum output power of the PA - Internal loss. The maximum output power
is measured at the antenna port.
l The LTE receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 5 MHz channel
bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.
l The 11 configuration indicates that two continuous carriers are configured and the spacing between the
center frequencies of two neighboring carriers is 5 MHz. In 101 or 1001 configuration, discontinuous
carriers are configured. The value 0 indicates the spacing of 5 MHz. For example, the 1001 configuration
indicates that two discontinuous carriers are configured and the spacing between the center frequencies of
the two carriers is 15 MHz.
l When the DCU is used in GSM DCU+UMTS/GSM DCU+LTE FDD/GSM DCU+UMTS+LTE FDD
networking scenarios, the GSM mode does not involve receiver sensitivity.
