In our recent paper, we propose the first measurement-backed model of millimeter wave self-interference. Using our stochastic model, engineers can draw realizations of self-interference that exhibit the large-scale and small-scale spatial characteristics observed in our nearly 6.5 million measurements.

A paper by G. Y. Suk et al. proposes a computationally efficient beamforming design for full-duplex millimeter wave systems by relying on transmit and receive RF beams to prevent self-interference-induced receiver-side saturation.

We present STEER, which tackles a similar problem as our work LoneSTAR. STEER can enable a mmWave communication system to operate in a full-duplex fashion by strategically selecting transmit and receive beams that deliver high beamforming gain in desired directions while coupling low self-interference. This is achieved by leveraging small-scale phenomena observed in our recent measurement campaign of self-interference. STEER provides a means to use beamforming to mitigate self-interference while also allowing the mmWave system to conduct beam alignment.

We introduce LoneSTAR, an enabler of full-duplex mmWave communication systems through the design of analog beamforming codebooks that can deliver high gain and reduce self-interference. This allows a system to conduct beam alignment and use a single solution to serve any downlink-uplink user pair in a full-duplex fashion.

Our paper measuring 28 GHz self-interference is available as early access in the IEEE Transactions on Wireless Communications. In this paper, we present statistically characterize self-interference and discover noteworthy small-scale variability that can be leveraged to reduce self-interference. We have published a GitHub repository containing related MATLAB code that allows researchers to draw realizations of mmWave self-interference based on our statistical models.

A paper by G. Y. Suk et al. on full-duplex integrated access and backhaul (IAB) is available as early access in the IEEE Wireless Communications Magazine. They present a full-duplex IAB framework, along with simulation and measurement results.

Our paper presenting 6.5 million measurements of self-interference at 28 GHz using phased arrays was presented at IEEE WCNC 2022.
December 01, 2021
Our paper illustrates that upgrading integrated access and backhaul (IAB) nodes with full-duplex capability can translate to latency and throughput gains far beyond the familiar doubling of spectral efficiency.

The ComSoc Full-Duplex ETI held a very interesting and insightful panel discussion with industry and academic experts on full-duplex.

Our journal paper on hybrid beamforming for mmWave full-duplex under limited receive dynamic range is available as early access in the IEEE Transactions on Wireless Communications . This paper tackles a number of practical challenges including limited channel knowledge, codebook-based beam alignment, a minimal number of RF chains, and a limited receive dynamic range. The hybrid beamforming design ensures that self-interference does not saturate receive-chain elements per-antenna nor those per-RF chain.
