RRU5309 Description

1 Overview

1

Overview

The RRU5309 is an outdoor remote radio unit that is powered by a power cabinet. It is the RF part of a distributed base station and can be installed near the antenna. The RRU5309 performs modulation, demodulation, data processing, and combination and division of baseband signals and RF signals. With the software-defined radio (SDR) technology, the RRU5309 can work in multiple modes through software configuration. With the feature of LTE FDD and NR uplink spectrum sharing, the RRU5309 can work in multiple modes that include NR in the uplink. The RRU5309 adopts a 2T2R design, which further improves the output power and carrier capacity.



The LTE FDD receiver sensitivity, as recommended in 3GPP TS 36.104, is measured under a 5 MHz bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs) standard.



The LTE NB-IoT receiver sensitivity, as recommended in 3GPP TS 36.104, is measured under a 200 KHz bandwidth and a 15 KHz subcarrier spacing based on the FRC A14-1 in Annex A.14 (π/2 BPSK, R = 1/3, 1 RB) standard.

2.4 Typical Output Power

Issue 03 (2019-03-30)



The "Output Power per Carrier" in the output power tables indicates the maximum output power supported by the network performance. The actually configured carrier power of GSM/UMTS/LTE FDD/NB-IoT can be less than or equal to the output power per carrier in the tables.



(a)

indicates that LTE NB-IoT cells can be deployed only in inband mode.

RRU5309 Description

2 Technical Specifications 

The following inband & guardband table describes the total output power of LTE FDD+LTE NB-IoT. For details about power configurations for LTE FDD and LTE NB-IoT, see the "L+M Configuration Combination" sheet in NB-IoT Typical Power Configurations (RRU) or NB-IoT Typical Power Configurations (RFU).



When two LTE FDD carriers are configured, it is recommended that the power spectrum density (PSD) of the two carriers be set to the same value. PSD = Carrier output power/Carrier bandwidth (1.4 MHz and 3 MHz bandwidths are considered as 5 MHz bandwidth in this formula.)



The output power is 1 dB less than the standard power when an RRU/RFU is located at a height of 3500 m to 4500 m; and is 2 dB less than the standard power when the RRU/RFU is located at a height of 4500 m to 6000 m.
