Introduction
Background For a separate-MPT multimode base station in co-transmission c o-transmission scenarios, the cotransmission port transmits and receives the local data and the passing data. In this case, the co-transmission port centrally schedules and manages the data of multiple RATs. For a co-MPT multimode base station in co-transmission scenarios, the co-transmission port transmits and receives only the local data, which includes i ncludes the data for all RATs of this base station. In this case, the co-transmission port centrally schedules and manages the data for all modes. To enable a co-transmission port to implement unied unied data data scheduling and management, diferentiation diferentiation and and fairness among diferent diferent service service types t ypes and RATs must be ensured. Moreover, Moreover, transmission resource congestion when all of the RATs have overlapping trac trac bursts bursts must be addressed. Therefore, Huawei introduces the Bandwidth Sharing of Multimode Base Station Co-T Co-Transmission feature. The diferentiation and diferentiation and fairness are described as follows: ● Diferentiation: Diferentiation: Transmission Transmission diferentiation diferentiation is is used when transmission bandwidth is limited. Transmission diferentiation diferentiation prioritizes prioritizes bandwidth use, with real-time services taking precedence over non-real-time services. servic es. ●
Fa Fairn irness ess:: If tr trans ansmis missio sion n conge congesti stion on occurs, occurs, ser servic vice e diferentiation diferentiation ensures ensures that real-time services are preferentially preferentially processed. As a result, non-real-time services may experience packet losses, which afect afect fairness fairness among non-realtime services. The transmission ow ow control control function enables each type of service or each RAT to be allocated a certain amount of bandwidth. This eliminates the possibility that a certain service or a certain RAT experiences service interruptions because of lack of transmission bandwidth.
This feature adopts four recommended transmission resource management strategies: mapping between trac trac classes classes and transmission priorities, trac limiting and shaping, load control, and ow ow control. control. For details about transmission resource management strategies for GSM, UMTS, LTE, and NR, see Transmission Resource Management for for GBSS, WCDMA RAN, eRAN, and 5G RAN.
Transmission Conguration Conguration Model Model As network trac trac volume volume increases, network transmission scenarios become increasingly complicated. For example, transmission ports transmission or boards need to be adjusted to support i nter-board inter -board functions. The traditional network Issue 01 (2022-03-08)

3 Introduction
conguration is complicated and struggles to meet the requirement for fast conguration is deployment on the live network. Therefore, Therefore, a new transmission conguration model is introduced to decouple transmission congurations congurations from from physical devices to simplify operations. A transmission conguration conguration model model can either be new or old, which is controlled by the GTRANSPARA GTRANSPARA..TRANSCFGMODE (5G gNodeB, LTE eNodeB) parameter. parameter. ●
When When th this is par paramet ameter er is set set to to OLD OLD,, the old transmission conguration conguration model model (referred to as old model) is used. In the old model, location information such (referred as cabinet, subrack, and slot numbers are congured, congured, the the transmission conguration is conguration is bound to physical devices, and IPv4 and IPv6 conguration objects above the IP layer are independent of each other.
●
When When th this is par paramet ameter er is set set to to NEW NEW,, the new transmission conguration model (referred to as new model) is used. In the new model, the transmission model is decoupled from the device model. That is, the transmission conguration does conguration does not contain cabinet, subrack, and slot numbers, and IPv4 and IPv6 conguration conguration objects objects above the IP layer are combined. This model facilitates the expansion of new transmission functions and requires fewer transmission conguration conguration parameters. parameters.
Compared with the old model, the new model incorporates an INTERFACE INTERFACE MO MO to isolate the upper layer from the physic physical al layer. layer. In this way, transmission conguration objects conguration objects are decoupled from physical devices. In addition, with the new model, when a transmission link is congured congured or or a transmission board or port is modied, modied, the the information such as the cabinet, subrack, and slot numbers as well as the subboard type only needs to be congured for congured for the physical layer and data link layer. The new model is applicable to base stations excluding GBTSs and pico base stations.

Bandwidth Sharing of Multimode Base Station Co-Transmission
4.1 Principles 4.1.1 Introduction The Bandwidth Sharing of Multimode Base Station Co-T Co-Transmission feature centrally manages GSM, UMTS, LTE, and NR transmission resources. When transmission resources are congested, this feature ensures the smooth processing of high-priority services and prevents GSM, UMTS, L LTE, TE, and NR services from impacting each other. This ensures high service quality and good user experience. This feature performs transmission resource management through the following strategies: mapping between trac trac classes classes and transmission priorities, trac limiting and shaping, load control, and ow ow control. control. If this feature is not enabled, the transmission resources for each RAT of a multimode base station are managed in the same way as those of a single-mode base station. For details about transmission resource management strategies for single-mode base stations, see Transmission Resource Management for for GBSS, WCDMA RAN, eRAN, and 5G RAN.
4.1.2 Application Networking This feature applies to networking schemes where both the local end (the multimode base station) and the peer end (the base station controller, MME, or SGW) use IP transmission (IP over FE/GE or IP over E1/T1). Figure 4-1 shows 4-1 shows the networking scheme for a GUL co-MPT base station in cotransmission scenarios.

The GSM, UMTS, and LTE sides of a multimode base station are referred to as the GBTS/ eGBTS, NodeB, and eNodeB, respectively. LTE can be LTE FDD, LTE TDD, or LTE NB-IoT. The NR side of a multimode base station is referred to as the gNodeB. ● Multim Multimode ode bas base e statio stations ns ar are e classied classied into into co-MPT and separate-MPT multimode base stations. The GSM side of a separate-MPT multimode base station can be either an eGBTS or a GBTS. The GSM side of a co-MPT multimode base station must be an eGBTS. The GBTS is not recommended for providing a co-transmission port to a separate-MPT multimode base station. This scenario is not covered in this document.
4.1.3 Transmission Strategies 4.1.3.1 Transmission Transmission Priorities In the Bandwidth Sharing of Multimode Base Station Co-T Co-Transmission ransmission feature, the mapping between GSM/UMTS/LTE/NR trac trac classes classes and transmission priorities must be congured congured to to ensure that diferentiated diferentiated services services (DifServ) (DifServ) are are provided based on transmission priorities.

For NB-IoT, NB-IoT, if control-plane c ontrol-plane EPS optimized transmission is used, NB-IoT services are carried on SCTP links. The transmission priority mapping for NB-IoT services is the transmission priority mapping for SCTP services.
DSCP DSCP is a eld eld in in an IP packet header to indicate the QoS requirements. The L3 network implements DifServ DifServ based based on the DSCP value. A multimode base station or a multimode base station controller sets the DSCP value for each IP packet based on the QoS requirements of each service ttype. ype. The L3 transmission device diferentiates diferentiates each each type of service and its QoS requirements according to the DSCP value, and then provides services such as resource allocation, queue scheduling, and packet discarding policies. This service is called per-hop behavior (PHB). All the network nodes for DifServ DifServ comply comply with the PHB according to the DSCP eld eld contained contained in an IP packet.

4.1.3.2 Trac Trac Limiting Limiting and Shaping When transmission network resources are limited, transmission devices may be incapable of receiving excess packets that arrive at the co-transmission port in a multimode base station. To prevent transmission devices from discarding packets, the trac trac limiting limiting function is introduced. Data services have unstable transmission rates due to unexpected trac trac bursts. bursts. The trac trac shaping shaping function is introduced to ensure stable in a multimode base station. The trac trac limiting limiting and shaping functions use rates the Generic Trac Shaping Trac Shaping (GTS) technology, which shapes irregular data ows, ows, or or trac trac ows ows that that do not match preset characteristics, to balance the bandwidths between upstream and downstream nodes. See Figure 4-2 4-2.. The trac limiting and shaping functions can limit the trac trac and and reduce packet loss caused by trac trac bursts. bursts.

4.1.3.3 Load Control Load control consists of the following functions: ●
Admission control Ensures the quality of admitted services by preventing excessive admission.
●
Load reshuing reshuing (LDR) (LDR) Increases the admission success rate and system capacity capacit y by relieving transmission load and preventing transmission resource congestion. L LTE TE does not support LDR.
●
Over Overlo load ad co con ntr trol ol (OL (OLC) Alleviates the negative impact of overload on high-priority users by quickly reducing transmission load.
Load control for each mode in a multimode base station in cco-transmission o-transmission scenarios is the same as load control in a single-mode base station. GSM and UMTS loads are controlled by the related base station controller and LTE LTE load is controlled by the eNodeB. NB-IoT and NR services do not support load control. For details about load control for GSM, UMTS, and LTE services, see Transmission Resource Management in in GBSS Feature Documentation , RAN Feature Documentation , and eRAN Feature Documentation , respectively.
4.1.3.4 Flow Control When the transmission bandwidth changes dynamically, the available bandwidth of the bottleneck node may be less than the limited bandwidth of the shared port. In this case, if the base station continues to send data based on the limited bandwidth, congestion occurs on the transport network. The ow ow control control algorithm estimates the bottleneck bandwidth of the network based on the detection of the transmission quality, and then dynamically adjusts the transmit bandwidth to ensure that it does not exceed the bottleneck bandwidth. GSM, UMTS, LTE, LTE, and NR support the ow ow control control algorithm in diferent diferent ways: ways: ●

The LTE/NR side performs uplink ow ow control control based on the detection result. In this scenario, if LTE/NR is not expected to use the detection result of the NodeB uplink bandwidth adaptive adjustment algorithm, two t wo transmission resource groups can be congured to congured to carry c arry UMTS and LTE/NR services separately. In this case, the uplink transmission ow ow control control of LTE/NR is independently controlled by LTE. For details, see Transmission Resource Management in in eRAN Feature Documentation . Precautions for Conguring Conguring the the NodeB HSDPA Adaptive Flow Control Algorithm (Downlink) After the HSDPA adaptive ow ow control control algorithm is enabled on the UMTS side, you are advised to enable enhanced enhanced HSDPA HSDPA ow ow control control and enhanced HSUPA Iub ow control ow control in the case of Iub congestion to prevent the ow ow control control algorithm from falsely decreasing the bandwidth when packet loss occurs on the transmission network due to non-congestion reasons (for example, packet loss caused by bit errors). ● Issue 01 (2022-03-08)

In most cases, intermediate transmission devices support queue scheduling. Layer 3 and Layer 2 intermediate transmission devices support eight queues. However, However, if intermediate transmission devices in the bearer network support less than eight queues, transmission priority combining strategies listed in Table 4-10 4-10 are are recommended. You can combine packets with diferent diferent DSCP DSCP values into one queue and combine packets with diferent diferent VLAN VLAN priorities into one queue. For example, if the intermediate transmission devices support six queues, packets whose DSCP values are 48 and 46 4 6 can be put into one queue. Accordingly, packets whose VLAN priorities are 6 and 5 can be put into one queue. This queue has the highest transmission priority.

Ba Band ndwi widt dth h pla plan n for for th the e bea beare rerr netw networ ork k Plan bandwidth for the bearer network based on services' servic es' bandwidth requirements and available bandwidth resources. When planning transmission bandwidth on the RAN side, ensure that the bandwidth between a base station and a base station controller is higher than the total bandwidth of real-time services. This guarantees the service quality of real-time services.
4.3.5 Others To provide guide on how to plan transmission bandwidth and transmission priorities for multimode base stations and multimode base station controllers, you need to know the network topology and transmission bandwidth plan of the bearer network, which include transmission bandwidth available in the bearer network and queues available on transmission devices. If bandwidth resources across the RATs are inappropriately allocated, reallocate the bandwidth resources based on the trac trac model. model. To implement the Bandwidth Sharing of Multimode Base Station Co-T Co-Transmission feature, the bearer network must support QoS management. Otherwise, this feature becomes invalid when the bearer network is congested. QoS management includes the following aspects: ● ●
