For transmission of the physical cell ID information, the number of cell IDs used in transmitting the existing cell ID information on a synchronization channel is increased or a part of existing cell IDs are reserved for transmitting the additional specific-cell ID information. If the number of cell IDs is to be increased, the number of cell ID groups related to a secondary synchronization channel is increased in a manner that removes ambiguity and collision, a cell ID related to a primary synchronization channel is added, which satisfies conjugate symmetry, information is transmitted based on a transmission timing relationship between a primary synchronization code and a secondary synchronization code, or a scrambling scheme is modified. When a part of the existing cell IDs are reserved, conjugate symmetry is also considered in relation to a primary synchronization channel and ambiguity and collision are also considered in relation to a secondary synchronization channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for transmitting physical layer ID information","description":"A method for transmitting IDs of cells of a specific type as physical cell ID information in addition to existing cell ID information is disclosed.
