Uni-RAN Technical Proposal
2 Uni-RAN Solution Designing
2.1 Uni-RAN Product Introduction
2.1.1 2G/3G SDR BTS Proposed for Vinaphone
ZTE proposes indoor Macro BS8800 for GSM900/1800MHz network and distributed RRU R8840 for UMTS2100MHz network by sharing the same BBU B8200 in BS8800. The SDR base station can switch GSM/UMTS (at 900MHz or 1800MHz) by software. This shows high integration at equipment side and essence of Uni-RAN solution, which is to share hardware as much as possible for 2G and 3G.
The RF module RSU60E (900MHz or 1800MHz) in indoor Macro BS8800 supports up to 6 GSM TRXs (80W ToC) and RRU R8840 supports up to 4 UMTS carriers (60W ToC), which can be set remotely by OMC-R.
The UBPG and BPC board are baseband processing board in B8200. UBPG supports up to 12 GSM TRXs and BPC board supports 6 carrier sectors,192 CE and 64.8Mbps throughput(DL) /17.3Mbps(UL). With 2 UBPG + 2 BPC configuration, we can provide 24 GSM TRX and 12 carrier sectors, 384 CE and 129.6Mbps(DL)/34.6Mbps(UL) so that the proposed 2G/3G SDR BTS (with RTU and software features) can support HSDPA 21.6Mbps(DL)/5.76Mbps(UL) per cell based on UMTS S222 configuration.
The proposed 2G/3G SDR BTS can provide 4 E1s(IP over E1) to BSC and 4 E1s(IP over E1) to RNC. In addition, 1 IP (FE) interface(optical) and 1 IP(FE) interface(electrical) are also provided to be shared by Abis and Iub interfaces..

Uni-RAN Technical Proposal
2.1.2 Uni-Controller Proposed for Vinaphone
ZTE proposes Uni-Controller for Vinaphone, which can work as Uni-Controller(iBSC) for GSM single mode and Uni-Controller(RNC) for UMTS single mode. Right now, Uni-Controller is able to work as dual mode step one (BSC/RNC co-rack), it can be upgraded to dual mode step two (BSC/RNC co-shelf) according to roadmap. ZTE will take our own cost to complete the upgrade according to Vinaphone’s request.
The Uni-Controller(iBSC) and Uni-Controller(RNC) utilize the universal all IP hardware platform. So, it is easy to share boards according to respective configuration. With unified hardware platform, Uni-Controller(iBSC) and Uni-Controller(RNC) are able to share the same rack.
The Uni-Controller(iBSC) is ready and fully compatible with GSM 900/1800 frequency band. Built-in PCU and GPRS (CS1 to CS4)/EDGE (MCS1 to MCS9) are supported by user plane board at Gb unit.
The Uni-Controller(RNC) is ready and fully compatible with UMTS 2100 frequency band and HSPA+ with the maximum peak rate up to 21.6Mbps per cell and HSUPA with the maximum peak rate up to 5.76 Mbps per cell are also supported.
The physical appearance of Uni-Controller is showed as below:

2.2 Proposed Uni-RAN Solution
2.2.1 Overall Sharing of Uni-RAN Hardware
The concept of Uni-RAN and SDR (Software Defined Radio) technology is to share hardware as much as possible so that it can save CAPEX of operator and guarantee long term protection of operator’s investment.
The following picture shows the physical structure of BBU (B8200) of ZTE SDR BTS. It is installed in BS8800 and shared by GSM and UMTS.

Uni-RAN Technical Proposal
Module Description
FAM FAN Module
On the basis of ZTE’s innovative design to share hardware as much as possible for Uni-RAN, BBU is almost fully shared by 2G/3G or even 4G for future evolution within the box of only 2U height. Regarding radio module (RSU module or RRU), it is also shared by 2G/3G or 4G based on SDR technology. The following picture shows the capability of overall sharing.
Figure 12 Overall sharing of BBU and RRU
The capability of BTS hardware sharing guarantees the SDR BTS to support multi-mode and multi-frequency. For example, 900MHz radio unit can be configured as GSM/UMTS dual mode and ready to evolve to LTE technology.
In terms of hardware sharing of Uni-Controller(iBSC) and Uni-Controller(RNC), since they are based on the same all IP hardware platform and architecture design, almost all hardware is shared. When the plug-in-unit is used to process GSM or UMTS services, it will be uploaded with corresponding software and given different logical name for easy distinction.
The following picture shows the physical structure of Uni-Controller.

Uni-RAN Technical Proposal
The Uni-Controller can be evolved from Step 1(Co-rack) to Step 2(Co-shelf) is showed as follows.

2.2.2 IP Co-transmission Solution for 2G/3G SDR BTS
As required in Pre-requisite in this tender,
The 2G/3G Integrated BTS offered must support co-transmission in IP mode to use the same transmission lines for both 2G and 3G without changing or adding software or hardware.
ZTE Confidential Proprietary © 2010 ZTE Corporation. All rights reserved. 11
Uni-RAN Technical Proposal
ZTE proposed 2G/3G SDR BTS can share one IP link by 2G and 3G packet without changing or adding any hardware. What’s more, this IP link can be shared by 4G LTE packet when the SDR BTS smoothly evolves to support LTE technology. Since GSM900/1800MHz and UMTS2100MHz share the same BBU, obviously, they can share the same IP link on CC board. This is fully compliant with VInaphone’s pre-requisite requirement without and deviation. The following picture shows the situation.
Figure 15 IP Co-transmission for 2G/3G/4G SDR BTS
2.2.3 IP Synchronization Solution for Uni-RAN
IEEE 1588v2 based IP clock is carried with UDP datagram between the Master Clock and the Slave Clock. In ZTE Uni-RAN solution, usually the Uni-Controller(iBSC) and Uni-Controller(RNC) act as the Master Clock and the 2G/3G SDR BTS as the Slave Clock, which is commercially used in Hong Kong CSL. IEEE 1588v2 enables clock synchronization without extra equipment investment.
The ICM board configured in Uni-Controller can work as integrated synchronization clock server for BSS or UTRAN system.

Uni-RAN Technical Proposal
2.2.3.1 Synchronization Solution of 2G/3G SDR BTS
B8200 supports all the traditional clock references and IEEE 1588, and in ZTE solution the primary clock reference is Line Clock (if available) and the IEEE 1588V2 is the second clock reference. All the clock reference is showed as follows:
Line clock (E1,primary)
BITS (2MHz)
IEEE1588 V2
GPS (Optional)
The 2G/3G SDR BTS clock source and its distribution architecture is showed as follows:
Figure 17 Clock Distribution Inner B8200
ZTE Confidential Proprietary © 2010 ZTE Corporation. All rights reserved. 13
Uni-RAN Technical Proposal
ZTE provides E1 and FE/GE for each 2G/3G SDR BTS as required in Vinaphone’s RFP, thus all the 2G/3G SDR BTS can get clock signal from BSC/RNC by E1 or IP line. The CC board of B8200 can get clock from BSC/RNC and distributes the clock signal to FS and BP. FS boards distribute the clock signal to RRU/RSU.
To improve the reliability of the system, we should set up a backup clock source for each 2G/3G SDR BTS and ZTE provides the traditional BITS (2MHz) synchronization solution.
2.2.3.2 Synchronization Solution of Uni-Controller
ZTE provides A-GPS function for Vinaphone as required and the clock board ICM which supports A-GPS function which is configured in the Uni-Controller(iBSC) and Uni-Controller(RNC) and it also work as clock server. What’s more, ZTE supports IEEE 1588 which is commercially used in Hong Kong CSL. The primary clock reference is GPS clock and the Line clock (STM-1) is the second clock reference. And all the clock reference is showed as follows:
GPS clock
Line clock (STM-1)
BITS (2MHz)
And the following picture shows the clock input and distribution architecture of Uni-Controller:
Figure 18 Uni-Controller Internal Clock Distribution
ZTE Confidential Proprietary © 2010 ZTE Corporation. All rights reserved. 14
Uni-RAN Technical Proposal
The clock source of each controller is GPS clock and the clock signal is distributed to GUIM board. Then GUIM boards will distribute clock signal to each board in the same shelf through the backplane.
According to the description above, we can come to the conclusion that if we want to make two or more controllers to get synchronization it only needs giving the same clock source to their GUIM board. And in ZTE solution, all the Uni-Controller(iBSC) and Uni-Controller(RNC) get the same clock source from GPS, so they are synchronized.
To improve the reliability of the system, we should set up a backup clock source for each controller and ZTE provides the traditional BITS (2MHz) synchronization solution for Uni-Controller(iBSC) and Uni-Controller(RNC).

2.2.4.5 Lightning Protection for Distributed RRU and DC Power System
For distributed RRU (R8840), it is installed outside on top of tower or pole so the lightning protection is very important to ensure the safety of RRU and DC power supply system. Besides internal design of lightning protection for RRU and DC power supply system, ZTE proposes outdoor lightning protection box (LPB) and indoor lightning protection box as the solution. The connection diagram is showed as follows.
Figure 23 Lightning Protection Connection
2.2.5 Refarming and Smooth Evolution
Vinaphone has 8.2MHz spectrum of 900MHz, it is similar with Hong Kong CSL. ZTE proposed 2G/3G SDR BTS is hardware ready for GSM/UMTS900MHz dual mode configuration. It is very easy for Vinaphone to refarm the 900MHz spectrum to support GU900MHz only through software configuration (Software Defined Radio technology) and even for LTE evolution.
The solution is commercially applied in Hong Kong CSL and Cell C in South Africa with more than 3000 sites in total. The following picture shows the smoothest refarming process.

Uni-RAN Technical Proposal
The proposed Uni-RAN solution is HSPA+ (Phase I) capable to provide 21Mbps for each cell. When the Uni-RAN network evolves to HSPA+ Phase II (e.g. on 2100MHz) which needs to support 2*2 MIMO or Dual Carrier (short for DC) to support 43Mbps downlink throughput, following upgrade process needs to be implemented.
Upgrade to MIMO: Adding 3 RRUs for a 3-sector site and software upgrade
Upgrade to DC: Software upgrade only
All the other existing hardware can be reused to save the Vinapohone’s investment. The following picture shows how ZTE proposed Uni-RAN evolves to HSPA+ Phase II.
Figure 25 Evolution to MIMO
Figure 26 Evolution to DC
ZTE Confidential Proprietary © 2010 ZTE Corporation. All rights reserved. 21
Uni-RAN Technical Proposal
Considering facility of implementation and Vinaphone’s frequency resource (3*UMTS carriers), ZTE suggests to choose DC (43Mbps DL) for HSPA+ (PhaseII) evolution by combining 2 carriers together for single user.
ZTE proposed Uni-RAN SDR BTS is also ready for LTE evolution. If Vinaphone plan to evolve UMTS2100MHz BTS(with MIMO ready) to support LTE on 2100MHz, only one LTE BP board and software upgrade is required. The following picture shows the procedure.
Figure 27 Evolution to LTE(2100MHz)
If Vinaphone gets LTE license at 2.6GHz, the proposed SDR BTS is also capable of upgrade to 2.6GHz LTE by adding LTE BP card and RRU to support 2.6GHz spectrum. The following picture shows the procedure.
