Low-cost IoT applications that 6G is intended to serve may be impractical unless phase noise mitigation can be applied on each uplink and downlink message. Accordingly, a single-branch phase-tracking reference is disclosed occupying just a single resource element, in which one quadrature branch is transmitted with a predetermined maximum modulation amplitude, and the other branch has zero amplitude. The receiver can then quantify the phase noise (or the phase rotation angle) according to a ratio of the as-received branch amplitudes, and mitigate a concurrent message by de-rotating each message element by the same phase angle, thereby restoring high reliability at high frequencies at negligible cost."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Scheduling single-branch phase-tracking references in 5G and 6G","description":"5G and especially 6G are susceptible to phase faults due to rapid phase fluctuations, usually in the local oscillator of the user device.
