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.

5 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.).
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).
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 –
Issue Draft A (2020-12-29)
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.

5 RF Output Power Configuration Rules
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.)
