A UE monitors a new radio discovery signal (NRDS-U) window in an unlicensed band for a DRS transmission that is constrained to be transmitted within the NRDS-U window. The UE determines initial access information, including an offset that indicates when the DRS transmission occurs within the NRDS-U window, and engages in initial access dependent on the offset. The offset is from a radio frame or half radio frame boundary or the start of the NRDS-U window. The offset is indicated in three least/most significant bits an SSB index or from an sl-offset field in a MIB of the SSB. When the base station uses a DFS channel, the base station transmits a periodic signal to emulate a radar signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PBCH content for NR unlicensed","description":"Systems and methods of providing timing information for initial access in an unlicensed band are described.
