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-CDMA)

4G only (LTE )1

Multi-technologies, using different modules for each technology:

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

2G/4G (GSM/LTE)1

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

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

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

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

2G/4G (GSM/LTE) 1

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

2G/3G/4G (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 down to 4.2 MHz, thus, GSM and W-CDMA signals 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 of SM SFP are available:

The Single Mode Single 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 ensuringinventory information reporting.

The remote inventory functionality allows the W-CDMA OAM access to determine the

state of the RRH.

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 the remote site

An optical module on the Node B site, or a SUMx 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 a maximum of two managed cells per RRH. As a example, a maximum of

twelve remote cells can be provisioned with six RRH in a full 3G solution.

Daisy chain configuration

More cells can be provisioned by daisy-chaining three RRHs (or RFMs) to a single fiberlink coming from the BBU, or the SUMx.

Sector or repeater configuration

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

Sector mode to use the RRH as another remote sector not configured at Node B

Repeater mode to use the RRH as a local sector configured at Node B. This allows to

extend 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

Combined configurations

The connection scheme can also be a combination of chain and ring and star as shown in

the next figure.

Multi-Standard configuration

The RRH can also be configured in a multi-technology environment as shown in the next

figure.

Multiple RRH per cell (optional)

To extend mobility coverage without adding cells to a Node B, Multiple RRH Sets (MRS)

can be used following the next rules:

An MRS contains one Cell-Mode RRH (CM RRH) acting as a normal cell, and

several Repeater-Mode RRHs (RM RRHs) acting as repeaters.

Up to four RM RRHs can be set in star or daisy-chain configuration.

Up to three MRSs can be connected to a d2U Node B in star configuration; and up to

six in daisy-chain configuration.

One MRS can support up to 12 cells and up to four carriers.

One BBU can support up to 12 RRHs.

OAM principles

OAM mastership rules

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.
