BTS Description

4.2

Nokia UltraSite WCDMA BTS architecture In the uplink path, the BTS receives signals from the UE; in the downlink path, the BTS sends signals to the UE. Uplink and downlink signals travel through the air interface (Uu) on different frequencies, the higher frequency carrying downlink signals. Uplink path

The antenna picks up a signal from the UE through the air interface. The antenna passes the signal to the optional MHA and Bias-T units and further on to the antenna connectors at the BTS cabinet top. The signal then goes through the Antenna Filter Unit (WAF) to the Transmitter and Receiver Unit (WTR). The WTR unit converts the received signal to a digital format and sends it to the baseband unit for further processing. The signal passes the Summing and Multiplexing Unit(s) (WSM) which provides the so-called pooled WSP capacity feature and is then routed to the allocated WSP unit. The WSP sends the processed signal to the Application Manager Unit (WAM) which passes the signal to the ATM Cross-connect Unit (AXU). The AXU unit sends the signal to the Interface Unit (IFU) which then passes the signal through the Iub interface to the RNC. Downlink path

The RNC receives a signal from the network and sends the signal to the IFU unit through the Iub interface. The IFU unit passes the signal to the AXU unit. The AXU unit then switches the signal to the allocated WAM unit for ATM termination. The WAM unit unpacks the ATM frame and sends the signal to the allocated WSP unit for digital processing. The WSP unit sends the processed signal to the WTR unit via the WSM unit(s). In the WTR unit, the signal is converted from digital to analog and modulated to the carrier frequency. The WTR unit then sends the signal to the Power Amplifier Unit (WPA) through a WIC unit. WPA amplifies the TX RF-signal to the final RF-power level. The WAF unit sends the signal to the antenna connectors at the BTS cabinet top. The signal then goes through the optional Bias-T and MHA units to the antenna which passes the signal through the air interface to the UE. See the diagram below.

Transmission

5.1

Transmission interfaces Transmission functionality is integrated in the WCDMA BTS. The transmission between the RNC and the BTSs (Iub interface) is based on ATM. It is possible to use the already available PDH or SDH based transmission networks (for example E1, STM-1 and so on). The WCDMA ATM Iub traffic can be transported over the existing transmission systems by using inverse multiplexing (IMA). IMA combines 2/1.5/6.3 Mbit/s connections to one ATM connection, and vice versa. There is no immediate reason to change or modify the existing access network, except for the necessary capacity upgrades due to increased traffic. The RAN (BTS-RNC) transmission can be based on star, chain, tree, and loop topologies. The physical transmission links can be shared between the WCDMA generated traffic and the second generation mobile traffic and fixed traffic. Each Nokia UltraSite WCDMA BTS has an integrated ATM switch, called the ATM Cross-connect (AXC) Node, for communication between the sectors inside the BTS, towards the RNC, and towards other BTSs. The AXC is constructed of one AXU unit and 1 to 5 Interface Units (IFUs). The AXU unit performs the main ATM functionality for the communication within the BTS and provides the connections to other network elements. The IFUs provide the physical connection to the network. The IFUs currently available for Nokia UltraSite WCDMA BTS are the IFUs A/ C/D and E. They support the following transmission interfaces, respectively: .

6.3

Software updates Nokia UltraSite WCDMA BTS can store two SW packages in its memory. SW can be loaded either locally with the element manager SW, or remotely from the RNC or Nokia NetAct ™ (via the RNC). Local SW downloading is typically done only when Nokia NetAct ™ connection is missing, that is, during the commissioning. Nokia UltraSite WCDMA BTS SW can be downloaded as a background operation without interrupting the BTS operation. The new SW can be activated at any time suitable for the operator. Only downloadable SW is used in Nokia UltraSite WCDMA BTS. The SW can be downloaded and updated from Nokia NetAct ™. This procedure is centralised, which means that several BTSs can be upgraded with the new SW either simultaneously or one by one. Nokia UltraSite WCDMA BTS keeps the current and a previous SW package in its flash memory. In the case of, for example, a power cut, the current SW package will be brought into use from the flash memory in a few seconds.

6.4

External alarms and controls The BTS inputs and outputs can be configured and tested locally on the Nokia UltraSite WCDMA BTS site with the element manager SW. There are 24 userdefinable external inputs and 6 user-controllable outputs available. These can be freely configured to support different observation or control needs at the BTS site. In normal operation, the BTS's external alarms and control outputs are managed from Nokia NetAct ™ after they have been configured.

# Nokia Corporation


Units

Nokia UltraSite WCDMA BTS Optima Compact Outdoor (WREB) and Supreme Indoor (WINB) use only Rel2 units.

Transmitter and Receiver unit, WTRA (Rel1)

On the transmit side, the WCDMA Transmitter and Receiver unit (WTR) receives digital data from the Signal Processing unit (WSP) via the Summing and Multiplexing unit (WSM) and performs modulation and up conversion of the carrier, which is amplified by the Power Amplifier (WPA). On the receive side, the WTR performs channel selection and down conversion for the selected carrier. The received signal is digitised and connected to the WSP via the WSM. The main features of the WTRA unit are: .

.

.

Two receivers (RX1 and RX2) and one transmitter (TX1) RX band 1920-1980 MHz and TX band 2110-2170 MHz (duplex separation of 190 MHz) Implementation from baseband to the RF in TX and from RF to baseband in RX

.

Digital IF sampling with 61.44 MHz clock

.

Internal VCXO for high quality clock reference

Transmitter and Receiver unit, WTRB (Rel2)

The Rel2 WTR unit (WTRB) offers double the capacity of the Rel1 WTR unit (WTRA). It contains two separate TRXs that can be used independently from each other. TRXs of the WTRB can operate on the same frequency or, if necessary, on different frequencies. The unit offers also combined output (TX1 + TX2). WTRAs and WTRBs can be used in the same cabinet. The features of the WTRB are the following: .

.

.


Two independent diversity receivers, each consisting of two RX paths resulting in a total of four RX paths (RXM1, RXD1, RXM2 and RXD2), and two independent transmitters (TX1 and TX2) RX band 1920-1980 MHz and TX band 2110-2170 MHz, duplex separation of 190 MHz (WTRB can support also variable duplex separation) Implementation from baseband to RF in TX and from RF to baseband in RX

Transmitter and Receiver unit, WTRD

The WTRD unit is a 2100 MHz frequency variant. WTRD provides RF functions for two carriers. The features of the WTRD are the following: .

Two independent TX paths (TX1 and TX2)

.

Four RX paths, two-diversity path (RXM1, RXD1, RXM2, and RXD2)

.

.

.

Digital dual carrier combining (in TX side) and and the sum signal is available from TX1 connector. In digital dual carrier case the channel spacing is 5 MHz. RX band 1920-1980 MHz, TX band 2110-2170 MHz, duplex separation of 190 MHz Only one TCP/IP address, sub-addresses sub-addresses are used to route messages on the unit

The WTRD also provides capability for the RF-test loop. The main function of the loop is to provide self-test functionality for the WTRD unit. This is performed by looping back the transmitter signal to the receivers. Only fixed transmit to receive frequency separation is supported.

8.2.2

Power Amplifier unit The Power Amplifier unit (WPA) provides linear amplification to WCDMA carriers with a constant power gain of 40 dB (WPAA/B) or 43 dB (WPAC/D/K). The WPAA/B/C WPAA/B/C/D /D amplifier is capable capable of supporting supporting up to four adjacent carriers in any 20 MHz section on the whole 60 MHz WCDMA allocation. The WPAK amplifiers support up to two carriers in 15 MHz occupied bandwidth. There are 30 W WPA units (WPAA/B/I/J) and 54 W WPA units (WPAC/D/K). The EEWPA (WPAI/J) is an efficiency enhanced version of the 30 W WPA. The EEWPA supports up to two adjacent carriers in 10 MHz bandwidth on the whole 60 MHz WCDMA allocation and can be used in all Rel2 HW configurations. To increase output power, two power amplifiers can be combined parallel by using the Input Combiner Unit (WIC) at the WPA input and the Output Combiner Unit (WOC) at the WPA output. 54 W versions cannot be combined parallel. All versions of the WPA and EEWPA can be used with a Wideband Power Divider unit (WPD) to divide output power to more than one sector (ROC configurations).

Note Nokia UltraSite WCDMA BTS Optima Compact Outdoor (WREB) uses only the DC version of the WPA unit.

8.2.3

Input Combiner The Input Combiner (WIC) unit connects output signals from the WTR unit to the WPA inputs. The 1900/2100 MHz variants use only A.205 or a later version of the WIC unit.

8.2.4

Output Combiner 2100 MHz variant: The Output Combiner (WOC) connects output signals from two WPAs to one Antenna Filter unit.

8.2.5

Antenna Filter unit The Antenna Filter (WAF) combines and isolates TX/RX signals and amplifies received signals. The unit contains a receiver multicoupler with four outputs for main branch and four outputs for diversity branch. The unit also has an RF Monitoring port for TX signal monitoring. The WAF is capable of feeding operating power to two Nokia UltraSite WCDMA Masthead Amplifier (MHA) units.

8.3

Baseband units Note Nokia UltraSite WCDMA BTS Optima Compact Outdoor (WREB) and Supreme Indoor (WINB) use only Rel2 units.


# Nokia Corporation

51 (65)

BTS Description

8.3.1

Summing and Multi ltiplexing ing unit The Wideband Summing and Multiplexing unit (WSM) sums the TX signals from the Signal Processing units (per antenna) or other WSMs to its own TX signal, and routes and sums the TX data to the appropriate WTRs. RX data is routed through the same path, but without summing. The operating principle is the same for both WSMA and WSMB. Rel1 (WSMA) and Rel2 (WSMB) WSMs

In Rel2 the WSMA unit is replaced with the WSMB because the WTRB doubles the capacity offered by the WTRA unit. This means that the data throughput of the WSMA has to be doubled for it to be capable of handling WTRBs. The WSMB provides this capacity.

8.3.2

Signal Processing unit The Signal Processing unit (WSP) performs RX and TX code channel processing, channel coding, and channel decoding functions. Summing of the TX code channels is performed for the code channels processed in the unit. The operating principle is the same for WSPA and WSPC. Rel1 (WSPA) and Rel2 (WSPC) WSPs

In Rel2 WSPC replaces the WSPA. It offers double the capacity of WSPA, that is, 64 HW channels. Rel1 and Rel2 WSP units can be used in the same cabinet from release RAN'04 onwards.

8.3.3

Application Manager unit The Application Manager unit (WAM) takes care of the control functions in Nokia WCDMA BTSs, such as BTS initialisation, configuration, and O&M functions. The unit also performs transport channel processing, ATM processing, telecom frame protocol handling and logical resource management. One of the WAM units in the BTS acts as the master O&M unit and the other one as the telecom master unit.The O&M master WAM takes care of the BTS power up control and the control and maintenance functions during run time. The telecom master WAM operates as the main signalling counterpart to serve the RNC. All other WAMs perform lower level O&M and telecom functions. If there is only one WAM unit in a BTS, it takes care of both master functions.

Temperature control system Heat Exchanger

The Heat Exchangers (WHX and WHEX) are used in Supreme Oudoor and Optima Compact Outdoor to provide cooling for baseband and transmission units. The WHX heat exchanger cells remove heat from the cabinet internal air circulation to the external air circulation. Fan module

The Fan module is a module of the cabinet core. It provides cooling to a specific subrack in the cabinet. It brings outside air into the BTS, while exhausting warm air from the cabinet. It provides a temperature dependent, variable airflow. The functions of the Fan module are controlled by the WAM unit.

Note Nokia UltraSite WCDMA BTS Optima Compact Outdoor (WREB) uses a Cooling Fan Unit (MFUA) for both RF and baseband subrack system.

Cabinet Fan

The Cabinet Fans provide cooling to WTR, WPA, and WPS units. The WAM controls the fan units according to temperature information from other units. The cooling is performed by adjusting the rotation speed of the fans. Smooth speed variations also minimise the noise generated by the fan units.

8.7

Optional items Heater Kit

The optional heater units are used in Nokia UltraSite WCDMA BTS Outdoor cabinets to cold start BTS operation in temperatures below -10°C (14°F). The heater is designed to be installed to the system on site. In the Supreme Outdoor cabinet, heater elements are required for the RF units only. In Optima Compact Outdoor, optional heaters are available for both RF units and the batteries.

BTS Description

Dust Filter

For Nokia UltraSite WCDMA BTS Optima Compact an optional Dust Filter (WDUA) is available for use in extreme climatic conditions where the air contains harmful particles like dust. WDUA is located in the RF section where ambient air is used for cooling purposes. When the Dust Filter is used, the maximum ambient temperature of the BTS is reduced to +40°C (104°F) .

Note The Dust Filter is not available for older versions of Nokia UltraSite WCDMA BTS Optima Compact Outdoor (WREA/WBBA) or Supreme Outdoor.

Q1 adapter

The Q1 adapter, or Site Management Interface Controller, operates with the IBBU in the Nokia UltraSite WCDMA BTS Optima Compact Outdoor. By connecting the Power Control Unit (PCU) to the Q1 bus in the BTS, the Q1 adapter interfaces the remote Local Management Port (LMP) function and Automatic polling function to the network. The Q1 adapter also enables control of the support system via the LMP for local management when on site. Co-site kit

Co-Site kits are used in an outdoor situation for connecting the roof of a Nokia UltraSite WCDMA BTS Outdoor cabinet to the roof of the various other UltraSite cabinets. It makes it possible to connect cables (DC, alarms, transmission, RF chaining, synchronisation) directly from one BTS to another. Smoke Detector

The outdoor cabinets support optional Smoke Detector units. OVP (Over-Voltage Protection)

Nokia UltraSite WCDMA BTSs support the optional Over-Voltage Protection. MHA

The WCDMA Masthead Amplifier (MHA) amplifies the uplink channel to compensate for antenna feeder line losses and balance uplink and downlink signals. A WCDMA MHA subsystem includes an MHA unit and a Bias-T. The Bias-T supplies MHAs at the mast with DC power through the feeder cable. The Bias-T implements VSWR-monitoring of the TX power in the antenna line.

58 (65)

# Nokia Corporation


Units

One WCDMA MHA system is used for each received path. Nokia supports up to 12 MHAs. Noise Reduction Kit

An optional Noise Reduction Kit is available for Outdoor BTSs to be used in sites where additional noise reduction is needed. The Kit can be fitted to the BTS when installing the cabinet or afterwards at the site without any transmission service interruptions. The only effect on the dimensions of the cabinet will be a slight increase in depth; the height and width of the BTS remain unchanged. Nokia RealTilt System

Nokia RealTilt is a fully integrated solution, which enables the optimisation of WCDMA networks by adjusting antenna tilt angle remotely from the network management system. Nokia RealTilt hardware consists of RealTilt Control Unit (RCU), RealTilt Electronic Tilt Adjuster (RTA), Power and control cabling, including RealTilt Lightning Protection Device (RLP). The RCU provides the interface between the base station and the RTA. The RCU unit is connected on the antenna side to RTA using a RS485 connection and on the base station side to the Ethernet port. The RCU can either be housed within the customer equipment space of the site support cabinet, or be pole mounted or wall mounted external to the BTS by using a weatherproof enclosure (IP67). Nokia Advanced Indoor Radio

Nokia Advanced Indoor Radio is an innovative solution for providing seamless indoor coverage in WCDMA networks. The system is fully integrated into the WCDMA RAN and consists of a wideband optical unit (WOU) inside the base station and wideband remote units (WRU) distributed throughout the building. The optical unit is connected to the remote units by optical links. The WOU unit reserves one power amplifier slot in the base station. The unit is an integral part of the internal communication system of the base station, which means that full O&M functionality is available without the use of any external devices. Wideband Optical Unit (WOU) replaces Power Amplifier (WPA) in Nokia Advanced Indoor Radio applications. One WOU unit reserves one WPA slot inside Nokia UltraSite WCDMA BTS. One WOU supports up to three Wideband Optical Modules (WOM) that are plugged to a WOU unit. WOM unit contains the BTS end of the optical links between the base station and the remote units. One WOM supports up to four wideband remote units.

GSM co-siting When utilising existing BTS sites, the compatibility of Nokia UltraSite WCDMA BTS with existing Nokia BTSs is a major issue. Nokia has designed Nokia UltraSite WCDMA BTS so that it can be installed as easily as possible to an existing site. The figure below illustrates the principle of how this can be achieved.

Compatibility has been considered for the following areas: Mechanics

Nokia UltraSite WCDMA BTS Optima Indoor and Supreme cabinets have similar space requirements as Nokia Talk-family and Nokia UltraSite EDGE BTSs have. Their floor installations also share the same fixing points. Optima Compact Outdoor is slightly wider.

GSM co-siting

Power system

When Nokia UltraSite WCDMA BTSs are installed to existing GSM BTS sites, the same kind of connections and power supplies can be used. Existing alarm connections, for example fire alarm and door alarm, can be connected to Nokia UltraSite WCDMA BTS as well. Customer-specific alarm input and control output electrical specifications are the same, which allows full interchangeability between connections. Nokia UltraSite Support cabinet can support both Nokia UltraSite EDGE and WCDMA BTSs. Antennas

To minimise the work of adding WCDMA antennas to GSM BTS sites, a part of the existing antenna infrastructure can be reused. A diplexer is an effective way to add Nokia UltraSite WCDMA BTS to the existing site if the additional loss can be tolerated in the antenna line. Actual losses are dependent on the combination, but for example in the GSM 900 / WCDMA case typical loss is less than 0.5 dB. Nokia will supply diplexers to all needed combinations. The Bias-T, with or without VSWR monitoring of the antenna line, supplies the MHA with a DC voltage from the BTS.

Transmission

Transmission of the existing sites can be efficiently utilised when WCDMA is added. This has been a very important transmission design criteria for Nokia UltraSite WCDMA BTSs. Nokia UltraSite WCDMA BTS is capable of connecting to the existing PDH/ SDH networks. If there is excess capacity or possibility to increase capacity in those networks, Nokia UltraSite WCDMA BTSs are able to use it. The same kind of physical interfaces will be used in both GSM and WCDMA systems. This will allow easy connection to the existing transmission. Transmission capacity can be shared by using fractional E1s or circuit emulation.
