Further, UEs may transmit SRSs to base stations in accordance with an SRS configuration. For example, a base station may provide SRS configuration information to a UE that indicates, for example, information related to SRS scheduling, subband information, a cyclic prefix length, a cyclic postfix length, listen-before-talk (LBT) type information, an SRS trigger, an SRS cancellation procedure, or any combinations thereof. Based on such SRS configuration information, a UE may perform partial subband SRS techniques, subband selection techniques, SRS bandwidth adaptation techniques, LBT type configuration techniques, etc."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sounding reference signal enhancements for unlicensed spectrum","description":"A user equipment (UE) may employ an extended cyclic prefix, a postfix, or both for sounding reference signal (SRS) transmissions, such that gaps between SRS transmissions are long enough for UE antenn","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11463885","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.
