2 Overview
2.1 Introduction
A key feature in the LampSite UMTS solution and the LampSite UMTS solution for outdoor
residential areas, WRFD-141202 Independent Demodulation of Signals from Multiple Small
Cell RRUs in One Cell combines the areas covered by multiple pRRUs or RRUs into one
logical cell.
The LampSite solution is mainly used for indoor coverage. This solution consists of the
baseband unit (BBU), RRU HUB (RHUB), and pico remote radio unit (pRRU).
The LampSite solution for outdoor residential areas is used for outdoor coverage in residential
areas. This solution consists of the baseband unit (BBU), optical RRU HUB (RHUB), and
remote radio unit (RRU). Currently, only the RRU3930E supports this feature. Descriptions
about networking of the LampSite solution in this document also apply to the LampSite
solution for outdoor residential areas.
The RRU3930E works only on one frequency band and supports LTE only, UMTS only, or
UMTS+LTE mixed deployment. It features a low transmit power and plays the same role as
the pRRU. Descriptions about the pRRU in this document also apply to the RRU3930E.
2.2 Benefits
Feature Benefits
The WRFD-141202 Independent Demodulation of Signals from Multiple Small Cell RRUs in
One Cell feature effectively mitigates interference and reduces handovers and call drops
through flexible capacity-based division of sectors and cells.
Feature Comparison
Currently, Huawei products support the following features that allow for multiple RRUs in
one cell: WRFD-021350 Independent Demodulation of Signals from Multiple RRUs in One
Cell and WRFD-010205 Cell Digital Combination and Split.
When the cell is configured with only one pRRU/RRU, this feature works in the same manner and
provides the same benefits as the WRFD-021350 Independent Demodulation of Signals from
Multiple RRUs in One Cell feature. When the cell is configured with only one cell sector
equipment group, this feature works in the same manner and yields the same benefits as the
WRFD-010205 Cell Digital Combination and Split feature.
2.3 Architecture
The WRFD-141202 Independent Demodulation of Signals from Multiple Small Cell RRUs in
One Cell feature uses the following techniques:
l Digital combination and splitting within a cell sector equipment group
l Independent demodulation for each cell sector equipment group
l Cell-level desensitization and group-level desensitization
In the uplink, an RHUB combines signals from a cell sector equipment group and then
separately sends signals from different cell sector equipment groups to the BBU for
independent demodulation. All cell sector equipment groups connected to the BBU form a
local cell. Cell-level desensitization and group-level desensitization are used to reduce
interference between cell sector equipment groups and between a LampSite cell and its
neighboring cells. Figure 2-1 illustrates how this feature works.
Figure 2-1 Working principles of Independent Demodulation of Signals from Multiple Small
Cell RRUs in One Cell
3 Technical Description
3.1 Concepts
Multiple pRRUs/RRUs in One Cell
By combining the areas covered by multiple pRRUs/RRUs into one cell, this technique helps
to achieve flexible network coverage. See Figure 3-1.
Cell sector equipment groups for different carriers can be consistent or inconsistent. In typical
scenarios, such groups on multiple UMTS carriers on the same frequency band are configured
in the same manner. See Figure 3-3.
Figure 3-3 Relationship between cell sector equipment groups and sector equipment groups
Digital splitting refers to the process of duplicating and sending signals to all pRRUs/RRUs in
a group.
Independent Demodulation
Independent demodulation, also called baseband signal combination or independent
demodulation and combination, refers to the process of independently demodulating uplink
signals from cell sector equipment groups in a cell and combining the groups into a local cell.
Uplink signals from pRRUs/RRUs in a cell sector equipment group, after undergoing cell-
and group-level digital desensitization, are combined on an RHUB, sent to the BBU for
independent demodulation, and then combined to form a local cell. Downlink signals for a
cell sector equipment group are divided into multiple outputs by the RHUB.
l If the pRRUs/RRUs are configured with one carrier and work in 1T2R mode,
– An RHUB (such as RHUB 2 or RHUB 3 in Figure 3-4) combines digital signals
from pRRUs/RRUs in a cell sector equipment group, and then sends the combined
signals to an upper-level RHUB or the BBU.
– A higher-level RHUB (such as RHUB 1 in Figure 3-4) combines signals from a
lower-level RHUB and signals from the directly connected pRRUs/RRUs in a cell
sector equipment group, and then sends the combined signals to the BBU.
l If each of the pRRUs/RRUs is configured with two carriers (carrier 1 as cell sector
equipment group 1 and carrier 2 as cell sector equipment group 2), the RHUB separately
combines signals transmitted over carrier 1 and carrier 2 of a sector equipment group,
and then separately sends combined signals of the two carriers to an upper-level RHUB
or the BBU.
l If the pRRUs/RRUs work in 1T2R mode, the RHUB separately combines signals from
the two RX channels (R0A and R0B) and sends combined signals to an upper-level
RHUB or the BBU.
Figure 3-5 illustrates digital combination for pRRUs with two carriers and working in 1T2R
mode.
Figure 3-5 Digital combination for pRRUs with two carriers and working in 1T2R mode
The BBU can combine signals from cell sector equipment groups on one or multiple CPRI
chains.
Cell-Level Desensitization
Cell-level desensitization minimizes uplink interference generated in LampSite cells/
LampSite cells covering outdoor residential areas due to the following reasons:
The desensitization intensity for minimizing interference caused by low MCL is hard to
calculate because the RTWP increase of cell-center UEs is not yet agreed upon in the industry.
For this reason, this part describes how to calculate cell-level desensitization intensity for
minimizing uplink interference caused by difference in uplink between LampSite and intra-
frequency neighboring macro cells. Ideally, a UE experiencing the same RSCP on both
LampSite and intra-frequency neighboring macro cells can enjoy the same SIR. Then, uplink
interference caused by low MCL can be alleviated.
where
l P_PCPICH_ LampSite indicates the downlink pilot transmit power of each carrier in a
LampSite cell. For example, the value is 9 dBm for a typical LampSite cell with two
carriers.
Group-Level Desensitization
Group-level desensitization is employed to balance the rise over thermal (RoT) among cell
sector equipment groups. The RoT caused by RF combination in cell sector equipment groups
differs from each other if these groups contain different numbers of pRRUs/RRUs. For
example, a cell sector equipment group with a few pRRUs/RRUs typically has a low RoT but
a high RoT in busy hours, and thereby is unable to deliver satisfactory network performance if
this group admits too many UEs. As exemplified in Figure 3-8, cell sector equipment group 2
has fewer pRRUs/RRUs than cell sector equipment group 1 but admits two more UEs (UE 5'
and UE 6'). Consequently, UE 5' and UE 6' have poor experience.
In this case, desensitization is required in cell sector equipment group 2 to increase its no-load
RTWP until it is balanced with that of cell sector equipment group 1. After desensitization is
implemented, admitted UEs have better experience even though UE 5' and UE 6' are rejected,
as shown in Figure 3-9.
Independent Demodulation of Signals from Multiple Small Cell RRUs in One Cell allows
automatic group-level desensitization, which is enabled by default.
Each pRRU/RRU in a cell sector equipment group is assigned the same desensitization
intensity (measured in dB), which is defined as follows:
DI_Static_intracell_RRU_i = {ΔPN_Max – 10 x lg(nj)}
Figure 3-10 Network topology 1 where pRRUs/RRUs in a cell sector equipment group are
connected to the same RHUB
In the example shown in Figure 3-11, some pRRUs/RRUs in cell sector equipment group 1
are connected to RHUB 1, while others are connected to RHUB 2.
Figure 3-11 Network topology 2 where the pRRUs/RRUs in a cell sector equipment group
are connected to different RHUBs
In the example shown in Figure 3-12, cell 1 has two cell sector equipment groups, and signals
from the groups are forwarded to the same baseband processing unit in the BBU over
different CPRI ports.

5 Network Impact
System Capacity
l Compared with the scheme of deploying one pRRU/RRU for one cell, this feature affects
system capacity as follows:
– In the uplink, multiple pRRUs/RRUs are grouped into a cell, independent
demodulation is used for each cell sector equipment group, so the uplink capacity of
a cell sector equipment group equals the capacity of a common cell. Therefore, this
feature has no or negative impact on system capacity, depending on the number of
cell sector equipment groups.
– In the downlink, this feature decreases system capacity because multiple pRRUs/
RRUs are deployed in one cell.
l Compared with the Cell Digital Combination and Split feature, this feature affects
system capacity as follows:
– In the uplink, this feature has positive impact on system capacity. If a cell is
configured with six cell sector equipment groups, the traffic is fully balanced, and
there is no overlapping area between pRRUs/RRUs, the maximum capacity gain
can reach 500%. If a cell is configured with 12 cell sector equipment groups, the
traffic is fully balanced, and there is no overlapping area between pRRUs/RRUs,
the maximum capacity gain can reach 1100%.
– In the downlink, this feature has no impact on system capacity.
l Compared with the Independent Demodulation of Signals from Multiple RRUs in One
Cell feature, this feature affects system capacity as follows:
– In the uplink, this feature decreases the system capacity if there are two or more
pRRUs/RRUs in a cell sector equipment group.
– In the downlink, this feature has no impact on system capacity.
Network Performance
Compared with the scheme of deploying one pRRU/RRU for one cell, this feature affects
network performance as follows:
l Network KPIs
– Downlink Ec/Io: Increases due to a decrease in inter-cell interference. Downlink
Ec/Io is measured by drive tests.
– Call drop rate: Reduces unless cell capacity is limited. The call drop rate includes
CS and PS call drop rates.

6.3 Planning
Figure 6-1 Network planning for a high-rise building with a small floor area
For the LampSite solution for outdoor residential areas, in coverage-focused scenarios, it is
good practice to plan all RRUs covering the entire residential area into the same cell.

NOTE
However, the cell sector equipment groups in a cell sometimes cannot have the absolutely same number
of pRRUs/RRUs because the pRRUs/RRUs of the same group must be connected to the same CPRI port
on the baseband processing unit. Once activated, the Independent Demodulation of Signals from
Multiple Small Cell RRUs in One Cell feature automatically enables group-level desensitization to
balance the uplink noise floor between cell sector equipment groups.

6.4.3 Precautions
The following are restrictions on deploying Independent Demodulation of Signals from
Multiple Small Cell RRUs in One Cell.
l pRRU/RRU
– One pRRU is configured with one UMTS RF daughter board by default and
supports one or two carriers.
– The pRRU works in 1T1R or 1T2R mode, and only antenna R0A transmits signals.
– One pRRU/RRU is configured with only one sector and one set of sector
equipment. If the pRRU/RRU supports two carriers, the sector and sector
equipment are shared by the two cells so that both antennas work in the same
TX/RX mode.
l Cell sector equipment group
– One cell sector equipment group accommodates 1 to 16 pRRUs/RRUs.
– pRRUs/RRUs of the same cell sector equipment group must be connected to the
same CPRI port on the baseband processing unit, while those of different cell sector
equipment groups can be connected to the same or different CPRI ports on the
baseband processing unit.
l Cell
– One cell can be covered by 1 to 96 pRRUs/RRUs. The minimum configuration is
one pRRU/RRU in a cell.
– For details about the number of supported cell sector equipment groups, see 6.3.3
Hardware Planning.
– pRRUs/RRUs and RRUs cannot cover the same cell.
– A cell can be configured with either pRRUs/RRUs working in 1T1R mode or
pRRUs/RRUs working in 1T2R mode, but cannot be configured with both modes.
– All sector equipment groups in a cell must be connected to the same baseband
processing unit.
6.4.4 Activation
Step 2 Run the NodeB MML command ADD BASEBANDEQM with BASEBANDEQMTYPE set
to UL(UL) to configure uplink baseband equipment.
Step 3 Run the NodeB MML command ADD BASEBANDEQM with BASEBANDEQMTYPE set
to DL(DL) to configure downlink baseband equipment.
Step 4 Run the NodeB MML command ADD RRUCHAIN to configure an RRU chain connecting
the BBU and RHUBs.
Step 5 Run the NodeB MML command ADD RHUB to add an RHUB to an RRU chain or ring.
Step 6 Run the NodeB MML command ADD RRUCHAIN to configure a chain connecting the
RHUB and pRRUs/RRUs.
Step 7 Run the NodeB MML command ADD RRU to add a pRRU/RRU to an RHUB.
Step 8 (Optional) Run the NodeB MML command ADD LOCATION to add location information.
Step 9 Run the NodeB MML command ADD SECTOR to add a sector (one sector corresponds to
one pRRU/RRU).
Step 10 Run the NodeB MML command ADD SECTOREQM to add sector equipment (one set of
sector equipment corresponds to one sector).
Step 11 Run the NodeB MML command ADD ULOCELL to add a local cell.
For pPRUs, Local Cell Type must be set to MIXED_MULTIRRU_CELL. This command
can be used to add one to six cell sector equipment groups to a cell. When the number of cell
sector equipment groups in a cell exceeds six, you also need to perform Step 12 to add cell
sector equipment groups to the cell. Each cell sector equipment group supports one piece of
sector equipment. (In this case, each cell sector equipment group must support only piece of
sector equipment. To configure more than one piece of sector equipment, see Step 13.)
Step 12 (Optional) Run the NodeB MML command ADD ULOCELLSECTOREQMGRP to add a
sector equipment group to the local cell. One sector equipment group can be configured with
only one set of sector equipment.
Step 13 Run the NodeB MML command ADD ULOCELLSECTOREQMGRPITEM to add sector
equipment to an existing sector equipment group.
Step 14 Run the RNC MML command ADD UCELLQUICKSETUP to set up a cell.
Step 15 Run the RNC MML command ACT UCELL to activate each logical cell under the RNC.
NOTE
l During logical cell activation, TRXs are also being activated in batches on the NodeB. If there is a
large number of antennas in the cell, RRU activation may take some time. However, feature
activation is not affected. If you repeatedly activate and then deactivate a logical cell, logical cell
activation may fail.
l If the pRRU3911/pRRU3916/pRRU59xx is used and the operating frequency band of the new cell is
not within the valid range, the pRRU will be reset to make the frequency band take effect. The reset
will interrupt services on other frequency bands.

4. (Optional) After activating the logical cells, conduct drive tests or walking tests and
ensure that there are no coverage holes or weak coverage areas.
5. Run the LST ULOCELL or DSP ULOCELLDESENS command to check whether the
desensitization intensity in the cell is the same as the preset one.
Expected result: The desensitization intensity is the same as the preset one.
6.4.6 Deactivation
Step 1 (Optional) Run the MML command SET ULOCELLDESENS or MOD ULOCELL with
DI set to 0 to disable cell-level desensitization.
Step 2 Run the DEA UCELL command on the RNC to deactivate logical cells under the RNC.
Step 3 Run the NodeB MML command RMV ULOCELL to remove local cells from the NodeB.
Step 4 Run the NodeB MML command RMV SECTOREQM to remove sector equipment from the
NodeB.
Step 5 Run the NodeB MML command RMV SECTOR to remove sectors from the NodeB.

6.4.7 Reconfiguration
Using MML Commands
1. Run the NodeB MML command ADD ULOCELLSECTOREQMGRP to add a sector
equipment group with one set of sector equipment to a cell.
2. Run the NodeB MML command RMV ULOCELLSECTOREQMGRP to remove a
sector equipment group from a cell.
3. Run the NodeB MML command ADD ULOCELLSECTOREQMGRPITEM to add
sector equipment to a cell.
4. Run the NodeB MML command RMV ULOCELLSECTOREQMGRPITEM to
remove sector equipment from a cell.
5. Run the NodeB MML command MOD ULOCELLSECTOREQM to change the
maximum downlink transmit power for a set of sector equipment.
NOTE
For a local cell or a set of sector equipment, this command takes effect 30s after the execution.
6. Run the NodeB MML command SET ULOCELLDESENS to set desensitization
intensity for a cell.
Using both cell sector equipment group-level and cell-level performance counters helps
achieve more precise network monitoring and fault diagnosis.
If the performance of a cell sector equipment group differs significantly from that of other
groups, check the cell sector equipment group. If all the groups do not differ much in
performance, it is good practice to check cell-level settings. For example, if the proportion of
abnormal RL releases in a cell sector equipment group is obviously higher than that in other
sector equipment groups, check whether the pRRU/RRU is faulty, whether the pRRU/RRU is
deployed properly, and whether there is strong interference nearby.
6.7 Troubleshooting
Fault Description
l Configuring Independent Demodulation of Signals from Multiple Small Cell RRUs in
One Cell fails.
l After Independent Demodulation of Signals from Multiple Small Cell RRUs in One Cell
is activated, the local cell becomes unavailable.
l ALM-28203 Local Cell Unusable is reported during cell activation.
l ALM-28201 Local Cell Blocked, ALM-28203 Local Cell Unusable, or ALM-28206
Local Cell Capability Decline is reported while a cell is running this feature.
l Configuring the desensitization intensity fails.
Handling Suggestions
1. If any of the alarms listed in Table 6-10 is reported, take measures according to the
alarm reference.
2. If none of the relevant alarms are reported, check the parameter settings of the local cell
and ensure that they are correct and match the NodeB capabilities.

DLRES BTS390 ADD None None Meaning: Indicates the Dl BB Resource Allocation
MODE 0, ULOCE Mode. The DL baseband resource assignment mode of
BTS390 LL the local cell determines the assignment scope of the
0 MOD DL baseband resources. The cell is assigned with
WCDM ULOCE baseband resources according to the selected DL
A LL baseband resource assignment mode. If the WBBPa
board is not configured, any value is applicable to this
LST parameter. Downlink resources are allocated from the
ULOCE WBBPb board and its compatible boards. The
LL parameter value has no impact on the system. The
default value is recommended. If 64QAM is required
for the local cell, this parameter needs to be set to
INEBOARD(From the WBBPb and other new
boards).
