Introduction Overview

The RRH is deployed in networks that support different technologies. Installing the correct software is enough to migrate from one technology to another one. It can also be shared by different operators (RAN sharing). The RRH specified in this document operates in the following technologies: •

•

•

Single technology –

2G only (GSM)

–

3G only (W (W-CDMA) -CDMA)

–

4G only (L (LTE TE )1

Multi-technologies, using different different modules for each technology: –

2G/3G (GSM/W-CDMA)

–

2G/4G (GSM/LTE)1

–

3G/4G (W-CDMA/LTE (W-CDMA/LTE )

–

2G/3G/4G (GSM/W-CDMA/LTE) (GSM/W-CDMA/LTE) 1

Multi-technologies, using using the same module for the different technologies: –

2G/3G (GSM/W-CDMA)

–

2G/4G (GSM/LTE) 1

–

3G/4G (W-CDMA/LTE) (W-CDMA/LTE)1

–

2G/3G/4G (GSM/W-CDMA/LTE (GSM/W-CDMA/LTE1)

Note: 1

The RRH 2X40-09 is hardware ready to the support LTE technology but the feature is not yet implemented. The RRH performs the transmission and reception of radio frequencies in the corresponding frequency band. It also performs the baseband processing. It consists of one digital-analog board and two power amplifier boards. The RRH 2X40-900 operates in a reduced bandwidth bandwidth down to 4.2 MHz, thus, GSM and W-CDM W-CDMA A signal signalss use the same available spectrum. The RRH 2X40 supports antenna diversity. If the 3G (or 4G) technology is used, the RRH is linked to the d2U or to the BBU through a CPRI interface and optical fibers. If the 2G technology is used, the RRH is connected to the BSC through a central equipment called Station Unit Module (SUMx). This equipment is hosted either in an existing BTS rack, or in a dedicated Site Support Cabinet (SSC). The SSC also integrates AC/DC converters and batteries for power back-up. ....................................................................................................................................................................................................................................

....................................................................................................................................................................................................................................

Optical access

This function provides duplex optical communication towards the Node B site through optical fibers using Single-Mode or Multi-Mode propagation: •

•

In Single-Mode propagation, two variants variants of SM SFP are available: –

The Single Mode Single S ingle Fiber (SM SF), one fiber carries both downlink and uplink signals using Coarse Wavelength Division Multiplexing (CWDM).

–

The Single Mode Dual Fiber (SM DF), carries the DL/UL in two separate fibers, one fiber carries the downlink signal, and another fiber carries the uplink signal.

In Multi-Mode propagation, one fiber carries the downlink signal, and another fiber carries the uplink signal.

Configuration/supervision

This function is in charge of configuring and supervising the modules as well as ensuring inventory information reporting. The remote inventory functionality allows the W-CDMA OAM access to determine the state of the RRH.





....................................................................................................................................................................................................................................

Call processing

The call processing function is in charge of radio resource management inside the base station equipment. Call processing manages: •

W-CDMA WCDMA services as described described in 3GPP standards

Configurations Radio configurations

The RRH can be linked to the BBU, using different configurations: •

Star

•

Daisy-chain

•

Sector or repeater

The RRH is used as a: •

Full 2G module

•

Full 3G module

•

2G/3G module

In a full GSM configuration, the SUMx is directly connected to the RRH 2X40W with optical Ethernet cables (max. six RRH), while in a multistandard configuration the SUMx is connected to the W-CDMA/LTE BBU module by the optical Ethernet cable and CPRI. Star configuration

The star configuration information involves the following hardware components: •

RRH on on the remot remotee site site

•

An optical optical module module on the Node Node B site, site, or a SUMx board board

The implementation of the RRH solution allows to connect, in star configuration, a maximum of six RRH to a BBU, or three RRHs to a SUMx. Each RRH provides service to a single sector, which supports either a single-cell or a twin-cell configuration, allowing allow ing a maximum of two managed cells per RRH. RRH. As a example, a maximum of twelvee remote cells can be provisioned twelv provisioned with six RRH in a full 3G solut solution. ion.

Sector or repeater configuration

An RRH operates in one of the following modes selected from OAM: • •

Sector mode mode to use the RRH as another remote remote sector sector not configured configured at Node B Repeater mode to use the RRH as a local sector configur Repeater configured ed at Node B. This allows allows to extend coverage coverage of a local sector to rural or shadow areas.

When RRHs are used as repeaters on a 20-km optical fiber length, the cell size (set at the OMC) of the last RRH in the daisy-chain cannot exceed 5 km. To guarantee a continuity in mobility coverage, RRH cell management is based on the following parameters: •

Optical fiber length

•

Cell size

•

Soft handover (SHO) between local and remote cells

In 2G configuration the Operation and Maintenance Center (OMC 2G) is used as management system, while in 3G it is the Wireless Management System (WMS 3G). When RRH is in 2G and 3G mixed mode the 2G system (OMC 2G) is the master, and RRH acts as a virtual machine for 3G usage. Therefore some actions such as hardware reset,, software upgrade are only managed by the OMC 2G. reset This table provides the OAM mastership rules: Supervison
