MRFUd Description 1 Introduction



1

1 IntroductionThe MRFUd can be used in a BTS3900 (Ver.C)/BTS3900 (Ver.D), BTS3900A(Ver.C)/BTS3900A (Ver.D). The MRFUd performs modulation, demodulation, data

processing, and combination and division of baseband signals and RF signals. With the

Software Defined Radio (SDR) technology, the MRFUd can work either in GU or GLdual-mode through software configuration modification.

MRFUd has a dual-transmitter and dual-receiver structure, which supports higher outputpower and carrier capacity.

The receiver sensitivity of GSM, as recommended in 3GPP TS 51.021, is measured in the central

band (80% of the entire operating band, excluding the edge band) at the antenna connector on thecondition that the channel rate is 13 kbit/s and the Bit Error Rate (BER) is not higher than 2%.

The receiver sensitivity of UMTS, as recommended in 3GPP TS 25.104, is measured in the entire

operating band at the antenna connector on the condition that the channel rate is 12.2 kbit/s and theBER is not higher than 0.001.

The receiver sensitivity of LTE is measured, as recommended in 3GPP TS 36.104, under a 5 MHz

channel bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.

2.4 Output Power

MRFUd modules operating in GSM mode and in the 1800 MHz frequency band comply with thestandard EN 301 502 V9.2.1.

MRFUd modules operating in UMTS, LTE, or Multi-Standard Radio (MSR) mode and in 1800 MHzfrequency band comply with the standard ETSI EN 301 908 V5.2.1 and 3GPP TS 37.104.

For the MRFUd working in GSM mode: when the S1 or S2 configuration is applied, the maximumoutput power of each carrier on the MRFUd is 80 W. If the output power of 60 W or 80 W isrequired, the related license must be obtained. After design optimization, the 8PSK and GMSK

modulation schemes enable the same output power for each carrier on the MRFUd when any of theS1 through S6 configurations is used. When the S7 or S8 configuration is used, the license

controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the

MRFUd.

The output power is 1 dB lesser than the standard power when the MRFUd is located at a height of3500 m to 4500 m; and is 2 dB lesser than the standard power when the MRFUd is located at a

height of 4500 m to 6000 m.

Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and trafficmodel affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network

planning can be based on the power specification achieved by dynamic power allocation.

In power sharing mode, the power control and DTX functions must be enabled. In GBSS8.1, thedynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell,

GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and

GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, thedynamic power sharing feature can be used together with these features. However, the dynamicpower sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference

Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, andGBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

Power sharing assumes a random distribution of UEs in the cell.

Table 2-5,Table 2-6, Table 2-7,andTable 2-8 list the typical configurations of the MRFUd.

2.5 Power Consumption

The typical power consumption and the maximum power consumption are measured when the base

station works at a temperature of 25C. The typical power consumption for GSM is reached when the base station works with 30% load and

power control and DTX are enabled. The maximum power consumption for GSM is reached whenthe base station works with 100% load.

The typical power consumption for UMTS is reached when the base station works with 40% load.The maximum power consumption for UMTS is reached when the base station works with 100%load.

The typical power consumption for LTE is reached when the base station works with 50% load. Themaximum power consumption for LTE is reached when the base station works with 100% load.

LTE power consumption is calculated based on the 2 x 2 MIMO configuration. Two MRFUs areconfigured in each sector.
