Introduction
Long Term Evolution (LTE) is an evolved telecom standard. It provides various technical benefits to Evolved Universal Terrestrial Radio Access Network (E-UTRAN), including:
Reduced service delay
Higher user data rates
Increased spectral efficiency
Optimized support for packet services
Improved system capacity and coverage
LTE has flexible bandwidths, enhanced modulation schemes, and effective scheduling. In addition, LTE allows operators to use both original and new spectral resources to provide data and voice services.
1.1 Overview Focusing on customer-oriented innovation, Huawei launches a series of LTE products in its SingleBTS product portfolio. The LTE frequency division duplex (FDD) 3900 series base stations (referred to as the 3900 series eNodeBs in this document) fully utilize Huawei platform resources and use a variety of technologies to meet the challenges of mobile network development. The E-UTRAN NodeB (eNodeB) is used for radio access in the LTE system. The eNodeB mainly performs Radio Resource Management (RRM) functions such as air interface management, access control, mobility control, and User Equipment (UE) resource allocation. Multiple eNodeBs constitute an E-UTRAN system. The innovative design and flexible combinations of basic modules and auxiliary devices encourage Huawei to diversify 3900 series eNodeB products. Figure 1-1 shows the 3900 series eNodeBs.

1.2 Benefits Diverse Usage Scenarios and RF Module Types for Different Network Deployment Requirements Huawei provides two types of radio frequency (RF) modules: radio frequency unit (RFU) and remote radio unit (RRU), which can be installed based on installation scenarios for macro and distributed eNodeBs. Each RF module provides at least two TX channels and two RX channels (2T2R). The modules support main LTE frequency bands and the minimum requirement of 2x2 uplink and downlink multiple-input multiple-output (MIMO). RRUs that are designed with 2T4R or 4T4R are adopted to meet the requirement of higher MIMO. RF modules are also characterized by their support for various bandwidths, great TX power, and high power amplification efficiency. 3mRRU that supports multi-carrier, multi-mode, and MIMO is one of the smallest, lightest, and most-efficient RF modules in the industry. Diverse usage scenarios and RF module types can meet different network deployment requirements of operators.
SingleRAN Platform to Support Multi-Mode Base Stations and Smooth Network Evolution
As a SingleRAN solution, the 3900 series eNodeBs can share the mature platform with other base stations, such as the 3900 series base stations working in GSM or UMTS mode. Equipment of different standards can be installed in the same cabinet. An indoor cabinet or a BTS3900AL outdoor cabinet supports a maximum of five carriers and three standards (GSM, UMTS, and LTE).
The 3900 series eNodeBs enable smooth network upgrade by sharing equipment with other base stations working in the same frequency band according to the software-defined radio (SDR) technology. This protects the original investment and reduces the cost of network deployment.
Flexible Installation for Fast Network Deployment with a Low TCO Flexible installation of the 3900 series eNodeBs simplifies site acquisition and achieves fast network deployment with a low total cost of ownership (TCO). The BBU a baseband unit, can Issue 02 (2014-06-30)

2.5 BTS3900A Cabinet A BTS3900A cabinet consists of an RF cabinet (RFC) and a power cabinet, or of an RF cabinet and a transmission cabinet.
The RFC is installed outdoors and uses a direct ventilation system. The power cabinet or transmission cabinet can be stacked on top of the RFC. Together with the RFC, the power cabinet or transmission cabinet provides the power distribution and surge protection functions for the BBU and RFUs. An RFC can house a maximum of six RFUs.
If a 110 V AC or 220 V AC power supply is applied, an APM30H or APM30H (Ver.C) power cabinet is used and the BBU can be installed inside the power cabinet.
If a –48 V DC power supply is applied, a TMC11H or TMC11H (Ver.C) transmission cabinet is used and the BBU can be installed inside the transmission cabinet. NOTE
BTS3900A cabinets are of two versions: Ver.C, and Ver.D. The BTS3900A (Ver.C) cabinets can be APM30H (Ver.C) or TMC11H (Ver.C) cabinets. The BTS3900A (Ver.D) cabinets can be APM30H (Ver.D) or TMC11H (Ver.D) cabinets.
A single BTS3900A (Ver.C) cabinets can house a maximum of 6 RFUs and 1 BBU. A BTS3900A (Ver.D) can be configured with radio frequency units (RFUs) and remote radio units (RRUs). A BTS3900A (Ver.D) supports flexible networking and can be easily expanded or evolved.A single BTS3900A (Ver.D) cabinet can house a maximum of 12 RFUs, 9 RRUs (6 RRUs for 2 x 60 W, 3 RRUs for 2 x 40 W), and 2 BBUs. When the RFU and RRU are configured together on BTS3900A (Ver.D), the RFU and RRU can be configured on the same baseband processing board. If multiple baseband processing boards are available, it is recommended to configure the RFU and RRU on different baseband processing boards. NOTE
When BTS3900A (Ver.D) houses RRUs, an extra DCDU inside the cabinet is needed for the RRU power supply.
The internal structure of a BTS3900A cabinet supporting AC input power is taken as an example in the following figure. The BTS3900A cabinet supporting –48 V DC input power has the same internal structure as a cabinet supporting AC input power. However, the former uses different power modules.

2.9 LampSite solution 2.9.1 Overview The LampSite solution provides indoor coverage to indoor areas with high traffic, such as office buildings, shopping malls, bars, hotels, and parking lots. In the LampSite solution, the base station comprises the baseband unit (BBU), pico remote radio unit (pRRU), and RRU HUB (RHUB). These modules can be flexibly combined to meet different scenario requirements. Like the DBS3900, the LampSite uses the same type of BBU. The RHUB3908 and pRRU3901 are compact and light, and therefore they can be installed anywhere indoors. The RHUB3908, which is 1 U in height, can be installed in a cabinet, rack, shelf, or on a wall. The pRRU3901 can be installed on a wall or ceiling. In office buildings, BBUs are installed in an equipment room, and RHUBs and pRRUs are installed in the office areas, as shown in Figure 2-1.

NOTE
In SRAN9.0 or later: As listed Table 2-19, 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. Table 2-20 lists the number of required Ethernet cables for the LampSite solution in different scenarios. In the UMTS mode, the WBBPf or UBBPd board can be used as the baseband processing board. In the LTE mode, the LBBPd or UBBPd board can be used as the baseband board. The UBBPd board is recommended. When the UBBP board is used as the baseband board, the board supports only single-mode networks, not multi-mode networks. In the preceding tables, combination indicates combination of pRRU cells.
One pRRU has three slots, in which RF daughter boards in different modes can be configured to achieve flexible multi-mode configurations. Table 2-20 lists the number of required Ethernet cables for the LampSite solution in different scenarios.
