Title: I/Q Record-Playback in OAI

Abstract: Describe and demonstrate the capability to record and playback radio samples in OAI.

Title: LTE/5G Self-Backhauling with OAI

Abstract: A challenge for LTE/5G cell densification is the backhauling of the small cells, since the fiber-based backhauling is costly and is not always feasible given the physical environment. For this, a recent idea is to use LTE/5G self-backhauling, where an eNB/gNB can relay its data to another g/eNB through the use of LTE/5G access technology. In this study, we develop and evaluate an implementation of LTE Self-Backhauling building on OAI and commodity hardware for the LTE system. For this, we implement a self-backhauled eNodeB, which connects to another eNB through an LTE connection.

Title: Analysis and Design of Enhanced OFDM Waveforms with OAI

Abstract: The Fifth Generation of mobile communications (5G) is being standardized in order to reach higher data rates and deploy new services. Orthogonal Frequency Division Multiplexing (OFDM) has a high Out-of-Band Emissions (OBE) which forces us to leave wider guard bands, reducing so the spectral efficiency. Recently, we have proposed the Power Adapted – OFDM (PA-OFDM) which is capable of fulfilling the requirements of 5G and avoid the main issues of the proposed candidates. OpenAirInterface (OAI) is a powerful and flexible wireless technology platform based on the Long-Term Evolution (LTE) ecosystem, which offers the possibility of evaluating the entire mobile communication system. In this paper, we will evaluate the proposed waveform candidate using the OAI throughout some measurements.

Title: Development of Access Platform Technology based on Virtualization

Abstract: The key technologies of the 5G system are High Bandwidth, Low Latency and Massive Connectivity. The 5G mobile communication should provide users with personalized, localized and intelligent new concept services. Therefore, it is necessary to secure design and implementation technology that guarantees flexibility of its structure in addition to communication technology such as high speed, low delay, and concatenation. The 5G mobile communication infrastructure with virtualization can adapt and reconfigure communication functions adaptively to the environment, so that it can quickly reflect the needs of users and markets. The services of the 5G can be accommodated by sharing resources in one equipment, rather than requiring different devices for execution. The virtualization system is good candidate to support a converged 5G service. In this talk, we focus on the work in progress in virtualization of the base station including some use case, design and implementation.

Title: LTE Latency Reduction with Shortened TTI using OpenAirInterface

Abstract: Future wireless communication is delivering many new use cases demanding ultra-low latency, ultra-reliability or a combination of both high reliability and low latency (namely the ultra-reliable and low latency communications (URLLC) technology). Currently, new radio (NR) standardization has started rapidly in the 3GPP standardization with basic numerologies, functionalities, and cross-layers suitable solutions for URLLC. Similarly, LTE in its upcoming release (Rel. 15) is going to utilize the basic findings in NR together with the conducted achievements of the shorten transmission time interval (sTTI) study to enhance LTE operation for a range of reliability targets and latency constraints. Accordingly, with a focus on URLLC goals, Fraunhofer IIS has started steadily implementing the new sTTI physical structure and the identified improvements in data and control scheduling for low-latency. This is implemented by modifying OpenAirInterface protocol stack accordingly and restructure the code modules mainly for layer-1 and layer-2. Our talk gives more insights and details about our design aspects and proposed solutions. Furthermore, challenges for satisfying the ITU-IMT-2020/3GPP-TR38.913 requirements of URLLC as well as migration towards NR numerology is going to be discussed.
