O-RAN Software Community O-DU PHY with OAI-specific modifications

This repository is fork of the O-RAN-SC O-DU Phy project.

The OpenAirInterface (OAI) RAN project uses several parts:

• the Open Fronthaul Library (LibXRAN) for O-RAN Open Fronthaul implementation to communicate with Open RAN Radio Units (RUs)
• the shared memory interface WLS (libwls) for FAPI message exchange with MAC
• the AAL rte_bbdev.h for LDPC AAL integration is not sourced from this repository, but from DPDK itself. Therefore, it has been deleted from this repository.

Historically, OAI maintained a set of Git patches on top of the upstream O-DU PHY repository to support OAI-specific requirements. As these patches grew in size and complexity, maintaining them became increasingly difficult.

To streamline development and improve collaboration for both developers and users, we created this fork of the O-DU PHY project.

Scope and Goals

This fork will diverge from the upstream O-RAN-SC O-DU PHY project for seamless integration with OpenAirInterface. All enhancements and fixes are expected to align with OAI design principles and Open RAN specifications.

Licenses

This repository follows the same primary license as the upstream O-RAN-SC O-DU PHY project. Detailed licensing information can be found in Licenses.txt.
