IX2User

module interface

This module interface provides the fundamental structure for submodules of the LTE/NR protocol stack that need to interact with the LteX2Manager to utilize X2 communication to accomplish their tasks, such as handover, dual connectivity, and Coordinated Multi-Point.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
DualConnectivityManager	simple module	This module is responsible for bridging data-plane packets between PDCP entities of two eNodeBs or gNodeBs when Dual Connectivity is employed. The module directly interfaces with the LteX2Manager to transfer such packets over the X2 interface.
LteCompManagerBase	simple module	ALTERNATIVE:
LteCompManagerProportional	simple module	This module implements a simple CoMP (Coordinated Multi-Point) coordinated scheduling algorithm. A CompManager module within an eNodeB can be either a master or a slave. Slave nodes send the master node the number of RBs required to satisfy their users' load. The master node partitions the bandwidth based on these requests and sends back an indication of which RBs are available for transmission and which are not.
LteHandoverManager	simple module	This module is responsible for managing the exchange of messages during the handover process. It handles the signaling and coordination required to transfer both control and data-plane information from the source eNodeB to the target eNodeB. The module directly interfaces with the LteX2Manager to facilitate this inter-eNodeB communication.

Known subclasses

Name	Type	Description
IDualConnectivityManager	module interface	Interface for the Dual Connectivity Manager. This module extends the X2User module interface to define the basic contract that any Dual Connectivity Manager must adhere to.
ILteCompManager	module interface	The LteCompManager interface defines the structure for the CoMP Manager. It extends the X2User interface and provides the necessary parameters and configurations for managing Coordinated Multi-Point (CoMP) communications in LTE networks.
ILteHandoverManager	module interface	Interface for the Handover Manager. This module extends the X2User module interface to define the basic contract that any handover manager must adhere to.
