The method includes: receiving, by a first network device, resource group indication information sent by a network controller, where a resource indicated by the resource group indication information does not overlap a resource used by another network device; determining, by the first network device, a first search space based on a user equipment UE-specific search space and the resource group indication information; and sending, by the first network device, a first PDCCH to the terminal device through the first search space."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control channel transmission method, network device, network controller, and terminal device","description":"Embodiments of the application provide a control channel transmission method, a network device, a network controller, and a terminal device, to avoid a resource collision between physical downlink con","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11246142","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.
