1.1 | MC-RRH900 Theoretical Overview

5. MC-RRH Introduction
MC-RRH is a Multi-Carrier outdoor Remote Radio Head which can be mounted close to the antenna
This has the advantage to reduce feeder losses and therefore improve coverage.
It reduces also the required BTS footprint
MC-RRH is based on MCPA architecture
It’s having scalable capacity by simple remote configuration
MC-RRH is multi-standard capable:
Supports multi-mode operation of 2G & 3G
In next step LTE

6. MC-RRH Architecture
The MC-RRH architecture is based on 2 MCPA, each at 40W, in order to be MIMO ready with a single MC-RRH module.
An MC-RRH constitutes an independent network element (outdoor box) communicating with its BTS site manager (central box)

9. MC-RRH Benefits
Mounting MC-RRH close to the antenna eliminates feeder losses, lowering the RF power required and correspondingly reducing power consumption. Also it reduces feeder cost
MC-RRH is virtually a no-footprint solution and a noise-free (no fan) module: it minimizes impacts on the neighbourhood and makes negotiation with site owners easier
MC-RRH is multi-standard capable supporting simultaneous operation on 2G & 3G
The number of 2G carriers and the mode of operation 2G vs 2G+3G can be configured via remote configuration"

1.2 | Multi-Standard Distributed BTS solution

11. Overview
Alcatel-Lucent Multi-standard distributed BTS solution is based on the MC-RRH unit, built on the principle of MCPA technology
The components of the distributed BTS in 2G/3G multimode are:
RRH2x40: The main radio unit containing the transmitter and receiver functions as well as the GSM baseband processing.
AC/DC conversion: Required to provide 48V DC for the RRH2x40 and provide battery backup in case of loss of power grid
GSM SUMX19’’: Provides the transmission termination to 2G BSC and Base Station Control function. Also it’s the entity which is used to configure the MC-RRH
WCDMA D2U: Provides the transmission termination to 3G RNC and digital processing function
Antennas: Normal standard antennas to be used

MC-RRH 2G/3G optical connectivity:
Towards digital part of the NodeB using optical fibers supporting CPRI, carrying downlink and uplink (main and diversity) base band signals, and OAM information.
GSM traffic is carried via GE on optical links to the SUMx.
SFP modules have to be inserted in the SFP cage of the digital modules (SUMx/D2U) and MC-RRH.
In Multi-mode and SM-DF, the SFP used on each side are the same.
In single-mode /SF, the wavelength of the SFP on each side is different.

17. SUMX 19 Inch Characteristics (1/3)
The SUMX19’’ (Station Unit Module eXtended nineteen inch) is required to form with the RRH2x40 a distributed BTS. It realizes the following functions:
Transmission termination
Clock generation
SW download
Alarm collection
O&M functions
The SUMX19’’ box contains the same SUMX as it is used in the Alcatel-Lucent Macro cabinet. It comes in a standard mountable 19’’ housing and is intended to be mountable in every standard nineteen inch rack.
In addition to the SUMX in the Macro cabinet a daughter board is plugged to realize the optical interfaces to the RRH2x40 and it allows also the connection of a fiber based Abis transmission interface.
A SUMX19’’ is operating every RRH2x40 independent of the frequency band.

In WCDMA, the MC-RRH is connected to the 9326 D2U (CCM board) on CPRI links 1 to 3.
The D2U hosts 1 to 3 CEM boards. The number of CEM is dependent on the capacity required: Up to 2 frequencies per CEM, up to 6 cells per CEM (and 12 cells per D2U), 256 R99 CE & 128 HSxPA users / CEM.
The D2U supports on the Iub interface of the CCM:
Up to 8 PCM (4PCM on the mother board and 4 PCM on the MDA 4PCM)
or GE interface (the MDA 4PCM is then replaced by a MDA/GE, as shown in this figure ).

Detailed procedure for installation is available in “Distributed BTS Installation
Manual”

36. Frequency Allocation Notes
MC-RRH module covers frequency bandwidth of 25 MHz called ‘PA RF BW’ or ‘MC-RRH module frequency span’
The spectrum is 35 MHz large in 900 band (PGSM + EGSM)
The frequency allocation of 2G/3G carriers defined on MC-RRH shall use a frequency window smaller than the MC-RRH module frequency span.
According to the carriers used , this limited bandwidth (25 MHZ) is shifted within the 35 MHz
Apart from that, as general rule of frequency allocation, proper 2G/3G planning should be followed in order to avoid interferences between the two technologies
