The method of performing NL for a RU in a base station having a structure of a C-RAN, performed between a C-RAN base station body and a RU in the C-RAN supporting multiple cells and multiple RUs, includes the steps of: (a) searching for, by the C-RAN base station body, RU configuration (a cell-RU combination) information constructed therein to instruct an RU that is to perform NL to perform the NL while instructing a RU using the same physical cell identifier (PCI) as the RU that is to perform the NL to turn off a radio frequency (RF) transmit (Tx) output thereof during performance of the NL of the RU that is to perform NL; (b) performing, by the RU instructed to perform the NL, the NL with a RF transmit (Tx) output thereof turned off; (c) turning on, by the RU instructed to perform the NL, the RF transmit (Tx) output thereof after completion of the performance of the NL while reporting a result of the performance of the NL and completion of the NL to the C-RAN base station body; and (d) instructing, by the C-RAN base station body, the RU using the same PCI to turn on the RF transmit (Tx) output thereof."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of performing network listening for RU in cloud-radio access network structure base station","description":"Provided is a method of performing network listening (NL) for a radio unit (RU) in a Cloud-Radio Access Network (C-RAN) structure base station in which a certain RU distinguishes and automatically det","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11477658","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.
