The method and apparatus comprises: receiving a synchronization signals and physical broadcast channel (SS/PBCH) block; determining whether a shared spectrum channel access is enabled; determining a first index of the SS/PBCH block as a candidate SS/PBCH block index (ISSB1) based on a number of candidate SS/PBCH blocks in a half frame; and determining a second index of the SS/PBCH block as an SS/PBCH block index (ISSB2) based on a quasi-co-location (QCL) parameter (Q) indicated by a PBCH in the SS/PBCH block, wherein the SS/PBCH block index (ISSB2) is determined as: ISSB2=ISSB1 mod Q based on a determination that the shared spectrum channel access is enabled, where mod is a modular operation; or ISSB2=ISSB1 based on the determination that the shared spectrum channel access is not enabled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for indexing of SS/PBCH block in unlicensed spectrum","description":"A method and apparatus of a user equipment (UE) in a wireless communication system is provided.
