Introduction

Purpose

In this repository we collect proposals for Opener, the Opener Initiative’s open NR+ reference implementation covering the MAC and upper layers.

Scope

Proposals cover the following areas:

• Medium Access Control (MAC) layer

• Data Link Control (DLC) layer

• Network layer signalling

• Management and control interfaces
