This module extends the LtePhyBase(1,2) module by providing the specific PHY functions on the eNodeB side. It is responsible for checking if a frame received on the air interface originates from a User Equipment (UE) connected to the eNB itself, and it provides the functions necessary to compute the Channel Status Information (CSI) for the UEs connected to it.

Inheritance diagram

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

Known subclasses

Name	Type	Description
LtePhyEnbD2D	simple module	This module extends the LTE PHY functionalities on the eNodeB side to support device-to-device (D2D) communications. Specifically, it enables the computation of Channel Status Information (CSI) related to the D2D link between two UEs, which still needs to be stored at the eNodeB for scheduling purposes.

Extends

Name	Type	Description
LtePhyBase	simple module	Base module for the Physical (PHY) layer of the LTE protocol stack.
