    摘要: 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. 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.
