a: AxC W in the Maximum Output Power column indicates that the number of TX channels of the RF module is A and the maximum output power of each TX channel is C W.

The maximum output power that can be configured for a single channel in a single frequency band of the RRU5513 is 100 W, and the maximum output power that can be configured for a single channel in two frequency bands is 100 W. That is, if 1800 MHz carriers have been configured on a single RF channel and the total output power of all 1800 MHz carriers is 50 W, the total output power of 2100 MHz carriers to be configured for this channel cannot exceed 50 W. NOTE ● The Typical Power Configurations document includes the configurable carrier combinations and the output power of each carrier in each combination. Before referring to this document, you must be familiar with the output power configuration rules. For details, see 4 RF Output Power Configuration Rules. ● Each value of Output Power per Carrier (W) in the Typical Power Configurations document indicates the maximum output power of each carrier under the corresponding configuration while ensuring the network performance. The actually configured carrier power of RF modules can be less than or equal to the value of Output Power per Carrier (W) in the document. The power configuration that is not supported in the document may be configurable on the software. Huawei can only promise the performance with the power configurations listed in the document.

The maximum level of cascading between an RRU and a BBU depends on the cascading capability of the RRU working in different RATs and the bandwidth resources of the CPRI ports on the BBU side. The following table lists the maximum level of cascading and maximum distance between an RRU and a BBU when the RRU works in a single mode. When the RRU works in multimode concurrency scenarios, the maximum level of cascading and maximum distance between the multimode RRU and a BBU are determined by the capabilities for the mode with the lowest capabilities.

4 RF Output Power Configuration Rules

RF Output Power Configuration Rules This chapter describes the rules for configuring RF output power.

General Rules ●

For an nT RF module (n is 2, 4, or 8), the restriction is as follows: , where PAi indicates the number of carriers of transmit channel i; Pi indicates the output power of each carrier of transmit channel i; PAt indicates the total number of carriers configured in this RF module; P indicates the maximum output power supported by each carrier.

●

The output power is 1 dB less than the standard power when an RF module is located at a height of 3500 m (11482.80 ft.) to 4500 m (14763.60 ft.); and is 2 dB less than the standard power when the RF module is located at a height of 4500 m (14763.60 ft.) to 6000 m (19684.80 ft.).

GSM Output Power Configuration Rules ●

Output Power per GSM Carrier With Dynamic Power Sharing is the available maximum output power for every carrier during dynamic power sharing. If this power is exceeded, the system cannot guarantee the network performance and will report an alarm.

●

If the output power per carrier on a single channel is required to be 60 W, the corresponding power license item must be purchased.

●

Before using the GSM power sharing function, ensure that the license item "Resource-BSC6900-LGMIDPS-Dynamic Power Sharing (per TRX)" has been purchased. To enable the power sharing function, run the SET GCELLCHMGAD command with QTRUPWRSHARE set to DYNAMIC and MultiGSMDynPWShareSW set to ON.

●

For the GBTS and eGBTS, the output power per carrier of the same RF module is the same. However, the unit of the output power per carrier is W for the GBTS and dBm for the eGBTS. The conversion relationship between unit W and unit dBm is as follows: dBm = 10 x log (1000 x W, 10). For example, when an RRU works in GSM mode, the output power per carrier that can be configured for the GBTS is 60 W (GMSK). Then, the output power per carrier that can be configured for the eGBTS is 10 x log (1000 x 60, 10), which is rounded off to 47.8 dBm (GMSK).

UMTS Output Power Configuration Rules The standard bandwidth per UMTS carrier is 5 MHz.

LTE FDD Output Power Configuration Rules When two LTE FDD carriers are configured, it is recommended that the power spectral 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.)

LTE NB-IoT Output Power Configuration Rules ●

The formulas for calculating the minimum NB-IoT power per PA for an RF module are as follows: –

When an NB-IoT cell works in guardband or inband mode, the minimum NB-IoT power per PA for an RF module is equal to the rated total power per PA divided by 10000. When an NB-IoT cell works in standalone mode, the minimum NB-IoT power per PA for an RF module is equal to the rated total power per PA divided by 100.

–

For example, the maximum output power of an RRU is 2x60 W. The minimum NB-IoT power per PA for the RRU when NB-IoT cells work in standalone mode is equal to 0.6 W (60 W/100).

●

In standalone mode, the bandwidth spacing between two NB-IoT carriers must be less than or equal to 300 kHz.

●

When the LTE bandwidth is 5 MHz, LTE NB-IoT cells cannot be deployed in guardband mode.

●

After the NB-IoT multi-carrier function is enabled, one NB-IoT multi-carrier cell can be configured with multiple NB-IoT carriers.

Issue 01 (2021-03-05)

–

When an NB-IoT multi-carrier cell is configured in standalone mode, a maximum of four NB-IoT carriers can be configured.

–

When an NB-IoT multi-carrier cell is configured in inband mode and the LTE bandwidth is 5 MHz, a maximum of four NB-IoT carriers can be configured. If the LTE bandwidth is 10/15/20 MHz, a maximum of eight NB-IoT carriers can be configured for an NB-IoT multi-carrier cell. Copyright © Huawei Technologies Co., Ltd.

4 RF Output Power Configuration Rules

When a cell is configured with multiple NB-IoT carriers, the cell can have only one anchor carrier but can have multiple non-anchor carriers. NOTE The NB-IoT multi-carrier function is an NB-IoT multi-carrier transmission technology introduced based on 3GPP Release 13. An NB-IoT cell can have multiple carriers and assigns UEs to multiple carriers to increase cell capacity. For details about this function and related parameter settings, see NB-IoT Enhancements (FDD) in the eRAN FDD Feature Documentation.

NR Output Power Configuration Rules To ensure the performance of an NR cell, the minimum configurable output power of the NR cell is equal to the total rated power per PA for an RF module (unit: W) divided by 16. For example, the maximum output power of an RRU is 2x80 W. When you configure an NR cell, the minimum configurable output power of the NR cell is 5 W (80 W/16). For a single 4T cell, it is recommended that the carriers configured on the four channels have the same power. Unbalanced power configurations are also supported. For details about unbalanced power configurations, see Cell Management in 5G RAN Feature Documentation.

Multimode Output Power Configuration Rules ●

GSM, UMTS, and LTE FDD carriers cannot be configured on the same channel simultaneously in a single frequency band.

●

The output power per carrier must be balanced among multiple channels if possible.

●

Non-MSR and MSR –

Non-MSR: Carriers of different RATs cannot be configured on the same RF channel. For example, a 2T RF module supports GU. If GSM carriers are configured on PA1, then UMTS carriers cannot be configured on PA1. That is, UMTS carriers can be configured only on PA2, and GSM carriers cannot be configured on PA2.

–

MSR: Carriers of different RATs can be configured on the same RF channel. For example, a 2T RF module supports GU. Both GSM carriers and UMTS carriers can be configured on PA1 or PA2 simultaneously.

●

The GU frequency spacing can be calculated using the following formula: GU frequency spacing ≥ [(GSM bandwidth/2) + (UMTS bandwidth/2)].

●

When one LTE FDD carrier and one NR FDD carrier are configured, it is recommended that the power spectral 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.)
