A connection may be established via a first UL/DL transmission/reception beam pair and a frequency tracking loop may be established and maintained to correct for frequency error (e.g., due to Doppler shift) of received transmissions at a receiving device. In cases where a beam switch is performed, and the UE and base station switch from the first UL/DL transmission/reception beam pair to a second UL/DL transmission/reception beam pair, and a frequency offset difference between the first and second UL/DL transmission/reception beam pairs may be applied to the frequency tracking loop. The frequency offset difference may be obtained from a table of frequency offset measurements of multiple UL/DL beam pairs using associated reference signal transmissions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency offset adjustment for beam switching in wireless communications","description":"Methods, systems, and devices for wireless communications are described that provide for adjustment of a frequency offset based on switching between uplink/downlink (UL/DL) transmission/reception beam","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11233559","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
