    摘要: A method for generating/transmitting a transmission-unit symbol sequence is disclosed. In the case of transmission information, the information is modulated in time and frequency domains on the basis of a predetermined transmission unit (e.g., a transmission time interval TTI or slot), simultaneous transmission of the information is made, and then a transmission unit symbol is generated/transmitted. A transmission sequence is masked in each symbol contained in one transmission unit. Symbol-unit circular shift (cyclic shift) is applied to the masked result, so that transmission efficiency increases. A control signal transmission method for supporting a variety of formats and a signal transmission method based on a prime-length sequence are also provided.

    摘要: A method of transmitting cyclic prefix length information when wireless access systems having different cyclic prefix lengths coexist is disclosed. The method of transmitting cyclic prefix length information comprises including the cyclic prefix length information in a preamble; and transmitting the preamble to a receiving end, whereby a transmitter can notify the receiving end of a current cyclic prefix length. Also, in a specific interval where a super frame header is defined, a single cyclic prefix length is used in a legacy support mode and a legacy disable mode, and cyclic prefix length information of other data or control channel is included in the super frame header and then transmitted to the receiving end. If different CP lengths are used in a legacy support mode of an evolved system, it is possible to solve a problem in detecting a control channel or a data channel, which may occur as the CP lengths are not distinguished from each other after preamble detection.

    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.
