4 Highlight of Huawei Proposed Network Solution 4.1 SRAN Product Overview

4.1.1 Multi-mode BSC Introduction

Figure 3 Multi-mode BSC

Inherit unified platform

Huawei multi-mode BSC6900 is based on self-developed PARC (Platform of Advanced Radio Controller) platform with IP/TDM dual-switching plane and high reliability. First-in-class capacity and density

BSC6900 has a First-in-class capacity (5100Cells and 8.04Gbps throughput for UMTS only/3072TRXs for GSM only/2304TRXs&5Gbps throughput for UMTS&GSM with 2 cabinets) in industry. BSC6900 has only 7 board types (excluded interface board), it saves a lot in spare management. This large capacity and multi-mode BSC not only provide a more flexible solution, but also meet the needs for the wireless broadband, which greatly protect our customers investment and being ready for the future technologies.4.1.2 4th Generation BTS Introduction

Figure 4 The 4th Generation BTS Portfolio

To come across various capacity and coverage requirements of operator, Huawei delivers a comprehensive BTS family that includes the Macro BTS, Distributed BTS, Micro BTS, etc to achieve seamless coverage. It is convergent platform between different BTS portfolio as well as convergent platform between GSM, UMTS and LTE.

Figure 5 Module design BTS

Huawei 4th Generation BTS 3900 series are based on self-developed platform HERT and adopt modular design. The 3900 series BTS include 3 parts, RRU (Remote Radio Unit)/RFU (Radio Frequency Unit)/BBU (Base Band Unit), which can be combined in different ways in order to adapt various scenarios. Modular design also simplifies the transportation, installation, maintenance of the BTS and the most significant is that the 4th Generation BTS can support GSM/UMTS/LTE simultaneously.

4.2 Highlight of Huawei Proposed Network Solution

4.2.1 Huaweis SingleRAN Solution

Huaweis SingleRAN solution is an industry first, unique convergent solution for operators who run more than one network, especially for GSM/UMTS multi-mode network. It is a series of future-oriented and convergent network solutions (such as Mutli-mode BSC, 4th generation BTS, IP RAN, GSM/UMTS inter-working algorithm, etc.) in relation to network architecture, transmission, facility and O&M system. SingleRAN makes the technology choices and network evolution simple, to greatly reduce access to the site, the equipment room building, transmission and other ancillary costs of the OPEX.

Huaweis SingleRAN solution embraces three essential elements (Uni-equipment, Uni-site and Uni-operation):

Figure 6 Key Figures of SingleRAN

4.2.2 Uni-Equipment Saving TCOUni-BTS: Uni-BTS makes Uni-site (Co-transmission &Co-auxiliary facilities) a reality. The modular and multi-mode design of Huaweis 4th Generation BTS, supporting 2G and 3G in one compact cabinet, presents the ultimate solution. With its integrated SDR and MCPA technologies (software defined radio and multiple carrier power amplifiers), the 4th Generation BTS also supports software upgrades from GSM to UMTS on a single module protecting operators earlier investments in existing GSM equipment and sharply reducing the time of UMTS deployment.

Figure 7 Co-cabinet Uni-BTS Solution In Different RF

Figure 8 SDR Uni-BTS Solution In Same RFUni-BSC: Uni-BSC makes Uni-Operation a reality. Huaweis solution provides the integration of GSM BSC and UMTS RNC into a multi-mode BSC. MBSC has the unified PARC platform, have 2G and 3G in the same cabinet, can provide IP/TDM dual-switching plane.2G and 3G can share many boards in MBSC, it saves a lot in spare management.

Figure 9 Uni-BSC4.2.3 High Transmission Efficiency

Figure 10 Co-Transmission Reduces Transmission CostIn multi-mode era, transmission cost counted as an important part of operators TCO. Constructing a cost-effective transmission network and being available for the need of the future evolution is a challenge for all the operators. Huaweis co-transmission solution can solve this problem. We adopt co-transmission based on IP network.

Figure 11 Co-transmission Solution Based on IP network

The GSM & UMTS system can transport the traffic on the same IP network through the same E1/FE/GE line. GSM & UMTS can share the transmission resources dynamically, so there will be a transmission convergent effect, and the transmission efficiency will be enhanced. 4.2.4 Wireless Broadband Facing Future NeedsEnhanced EDGE PerformanceEDGE brings triple throughput compare to GPRS. Huawei provides state-of-the-art algorithm to enhance the EDGE performance.

Link adaptation, incremental redundancy, intelligent initial codec scheme, GPRS&EDGE multiplexing and dynamic RLC ACK window algorithm will enhance the throughput. Delayed DL TBF release, extended UL TBF, immediate assignment moved to BTS, PDCH assignment moved to BTS and fast RRBP will reduce the access delay. Streaming QoS, PoC QoS, ARP, THP and adaptive adjustment of Uplink & Downlink Channels will enhance QoS. NACC, NC2 and PSI status will reduce the gap of cell reselection.

Figure 12 EDGE ThroughputSwitching to GERAN only need software upgrade in RF Part. The BBU3900 has 8 slots for base board, which supports the plug-and-play function. The BBUs hardware is ready for EDGE Evolution and need to insert an additional card (embedded card), which will enhance the capabilities of 32QAM UL/1.2high symbol rate.

Figure 13 Upgrade to UL 32QAMHigh Performance HSPA Solution

With self-designed HSPA chipset, high performance HSPA can be achieved in Huawei UMTS products from the very first day, supporting full performance HSDPA with 15 codes /14.4 Mbps per user on downlink and HSUPA with 5.76Mbps/user on uplink.

In order to save evolution investment and keep the leading position of UMTS, Huawei is recommending HSPA deployment strategy as follows:

High performance HSPA capability

The offered BTS and BSC should be high performance HSDPA and HSUPA capable equipment from day one, which supports full performance HSDPA and HSUPA phase 1. By adding baseband extension card, full performance HSUPA service can be achieved.

Large capacity RNCHSPA will bring high throughput requirement for RNC in comparison to R99 network. Accordingly, the RNC is required to support large capacity and high throughput for HSPA large traffic requirements. To facilitate capacity expansion and keep network topology simple, Huawei new BSC can support flexible capacity configuration and adapt different interface type.

Flexible RRM strategy

Advanced RRM algorithms help to utilize the radio resource effectively. Key functions for HSDPA are highlighted below:

1) Flexible code and dynamical power allocation

2) Code multiplexing in initial deployment

3) Parameters configurable scheduler

Coverage improvement

In HSDPA solution, Huawei supports HS-DPCCH preamble mode technology help the Node B to distinguish between DTX and ACK/NACK without requiring a large ACK transmit power. In this way, the uplink coverage gain is about 0.2dB to 0.9dB with different accompanying DPCH service.

Evolution to HSPA+/LTE

The evolution paths for both distributed BTS and macro BTS is shown as follows:

Figure 14 Smooth Evolution to HSPA+/LTE

The Baseband Unit BBU3900 has 6 slots for base board, which supports the plug-and-play function. The BBU is hardware ready for HSPA+ phase 1 (downlink 64QAM and MIMO 2 x 2) and only need to add new baseband card to support HSPA+ phase 2 (uplink 16QAM) and LTE respectively.

The RF Unit is hardware ready for HSPA+, LTE, and only need software upgrade to support HSPA+ and LTE at the same frequency band. 4.2.5 Huawei Green SolutionStackable design makes it possible for hand carry installation and flexible expansion. The macro outdoor BTS (BTS3900A) can work stably in the range of -40 to +50 degree Celsius. Air direct-ventilation design makes it more reliable without air condition or heat-exchanger for temperature adjustment. It has the same baseband and radio performance with indoor macro BTS.

Distributed BTS (DBS3900) separates traditional cabinet BTS into two parts, baseband unit (BBU) and remote radio unit (RRU). RRU can be mounted near the antenna to save feeder loss of 3 db and TMA (Tower Mounted Amplifier). They mark small size, large capacity and high integration. Therefore, we can provide a zero footprint solution thus fulfilling the desire of easier, faster site acquisition, installation and network deployment. Huawei 4th generation BTS can support multi plicate methods on power control, there are two main kinds:1.dynamically shut down idle resources, like cell, TRX and PSU boards,2.allocate accurate power according to actual traffic requirement, like BCCH power optimization and power optimization based on channel type. Based on these advanced and innovative power control technologies, Huawei 4th generation BTS can bring extra 10-25% power consumption saving.High effective digital power amplifier (DPA) can save the electrical power cost. With DPD+ A-Doherty technology, the PA efficiency is up to 40%.DBS3900 S111 typical power consumption is only 400W compared to the traditional common Node B of 1500W.

Figure 15 Power consumption cooperation4.2.6 Successful cases with Huawei SingleRAN Solution
