    • 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.
    • 公开了当具有不同的循环前缀长度的无线接入系统共存时发送循环前缀长度信息的方法。 发送循环前缀长度信息的方法包括在前同步码中包括循环前缀长度信息; 以及将前导码发送到接收端,由此发射机可以向接收端通知当前的循环前缀长度。 此外,在定义了超帧报头的特定间隔中,在传统支持模式和遗留禁用模式中使用单个循环前缀长度,并且其他数据或控制信道的循环前缀长度信息被包括在超帧报头中 然后发送到接收端。 如果在演进系统的传统支持模式中使用不同的CP长度,则可以解决检测控制信道或数据信道时的问题,这可能由于在前导码检测之后CP长度彼此不区分而发生。

    • A frame structure for flexibly supporting heterogeneous modes and TDD/FDD modes and a method for transmitting signals using the same are disclosed. A method for transmitting a signal using a preset frame structure in a communication system which supports a TDD mode and an FDD mode and supports two or more different communication schemes includes constructing a signal in units of the frames and transmitting the signal, wherein at least one of determination of a ratio of a DL region and a UL region within the frame when the communication system communicates according to the TDD mode allocation of a time region according to the modes of the communication schemes when the communication system communicates according to a heterogeneous mode supporting the two or more communication schemes and setting of a construction scheme of sub-frames within the frame in units of a prescribed number of the frames or super-frames, is performed on the basis of a specific unit comprised of n OFDM symbols corresponding to a multiple of a UL subchannelization unit.

    • 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.
    • 公开了一种用于发送特定类型的小区的ID作为物理小区ID信息以及现有小区ID信息的方法。 为了传输物理小区ID信息,在同步信道上发送现有小区ID信息中使用的小区ID的数量增加,或者为了发送附加特定小区ID信息而保留现有小区ID的一部分。 如果要增加小区ID的数量,则以消除歧义和冲突的方式增加与次同步信道相关的小区ID组的数量,添加与主同步信道相关的小区ID,其满足共轭对称 基于主同步码和辅同步码之间的发送定时关系来发送信息,或修改扰频方案。 当现有小区ID的一部分被保留时,也考虑与主同步信道相关的共轭对称性,并且还考虑与次同步信道相关的模糊性和冲突。
