摘要： A pilot symbol structure and a pilot transmission method for improving channel estimation performance in a wireless access system using multiple carriers are provided. In the method for transmitting subcarriers using a pilot structure, pilot subcarriers are repeatedly allocated at predetermined subcarrier spacings and at predetermined symbol spacings in a basic resource block, and the basic resource block is periodically and repeatedly allocated in a time domain and a frequency domain within a subframe, and then the pilot subcarriers and data subcarriers included in the subframe are transmitted. When one or more antennas are used, it is possible to transmit pilot symbols while maintaining predetermined spacings in the time domain and the frequency domain, thereby improving channel estimation performance.

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.
摘要翻译：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。
