Downlink control information (DCI) may be expanded to carry/transmit a beam/QCL (quasi co-location) indication for a control resource set (CORESET) for monitoring a next instance of a physical control channel. Error resilient design techniques may be employed to further improve device mobility while increasing the flexibility and reducing the latency for GC-PDCCH/PDCCH beam/QCL indications. For example, the aggregation level for select DCI (e.g. DCI in which the GC-PDCCH/PDCCH beam indication has changed) may be increased, the transmission of such select DCI may be limited to a certain (specified) aggregation level, and in case discontinuous transmission (DTX) is received, the base station may transmit both old and new beam/QCL indications."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hierarchical beamforming structure and transmission of beam indication to improve device mobility and reduce network traffic overhead in new radio (NR)","description":"A hierarchical beamforming structure may help reduce network traffic overhead for transmission of beam indication (information) and enable efficient Transmission Configuration Indication, while facili","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11272576","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.
