NRMacUe

simple module

This module provides functionalities for the Medium Access Control (MAC) of the New Radio (NR) protocol stack at the User Equipment (UE) side. In particular, it extends the LteMacUeD2D module by redefining functions to support different numerology parameterizations.

Inheritance diagram

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

Extends

Name	Type	Description
LteMacUeD2D	simple module	This module extends LTE MAC functionalities at the User Equipment side to support device-to-device (D2D) communications. Specifically, it customizes LteMacUe functionalities to support the transmission and reception of MAC Protocol Data Units (PDUs), Channel Status Information (CSI), and Buffer Status Reports (BSRs) over a D2D link. It supports D2D multicast transmission to nearby UEs belonging to a given multicast group.
