[0012] 参考图2,为上述表格1、2中的格式I、格式2、格式3、格式4的在一个时隙上的传输结构示意图。 [0012] Referring to Figure 2, the format 1 in the above table I, format 2, format 3, a schematic diagram of a transmission in a slot structure 4 format. 其中,左斜纹(45°斜线)表示短CP;右斜纹(135°斜线)表示长CP;子载波间隔即子载波宽度。 Wherein the twill left (45 ° hatched) represents the CP short; the right twill (135 ° hatched) represents the CP length; i.e., subcarrier spacing of subcarriers width.

[0013] 现有技术中,仅涉及UC/MC即15kHz子载波宽度下的同步信息发送、接收方法,为:将同步序列映射到同步信道(SCH, Synchronization Channel)所占用的时频资源上,发送出去。 [0013] In the prior art, relates only UC / MC i.e. synchronization information at 15kHz subcarrier width of the transmission, reception method, as follows: when the synchronization sequence is mapped to the synchronization channel (SCH, Synchronization Channel) occupied frequency resources, sent out. 终端通过检测所述同步序列,并运算得知有关同步的信息。 Terminal by detecting the synchronization sequence, and that information about the synchronization operation.

[0014] 具体而言,参考图3,为现有技术中占用15kHz子载波宽度的系统的频域结构示意图,对于采用15kHz的子载波间隔的通信系统,例如UC/MC情况下的前述格式I或格式2下的同步信道,在频域上占用系统带宽的中心960kHz带宽,占用中心的64个子载波。 [0014] Specifically, with reference to FIG. 3, a schematic diagram of a frequency domain occupied by the sub-system configuration 15kHz carrier width of the prior art, a communication system for a subcarrier spacing of 15kHz, for example, the form I at UC / MC where 2 format or the synchronization channel at, the center of the system bandwidth occupied bandwidth of 960kHz in the frequency domain and occupies 64 sub-carriers in the center.

[0015] 参考图4,为现有技术中同步信道在时域上的结构示意图(格式I的帧结构位置图):同步信道位于一个无线帧的第O个和第5个子帧,其中主同步信道(P-SCH,Primary-SCH)位于子巾贞O、子巾贞5的第一个时隙的最后一个符号,在图中以网格表示,辅同步信道(S-SCH,Secondary-SCH)位于该时隙的倒数第二个符号,在分别以以左斜纹(45°斜线)和右斜纹(135°斜线)表示。 [0015] Referring to FIG 4, the prior art synchronization channel structure diagram of channel in the time domain (format I frame configuration map to): a synchronization channel in a first O-th and 5 th radio frame, wherein the primary synchronization channel (P-SCH, Primary-SCH) is located in the last symbol of sub Zhen O towels, towels Zhen first sub-slot 5 in the figure represents a grid, secondary synchronization channel (S-SCH, secondary-SCH ) located in the slot penultimate symbols, respectively to the left in the twill (45 ° diagonal lines) and the right twill (135 ° diagonal lines).

[0016] 主同步信道上承载了主同步序列,辅同步信道上承载了辅同步序列。 [0016] a primary synchronization channel carries a primary synchronization sequence, the secondary synchronization channel carries a secondary synchronization sequences. 现有技术中主同步序列有3个,辅同步序列有170个。 The prior art, a primary synchronization sequence has three, 170 secondary synchronization sequences. 现有技术中同步信道同时还可以承载小区ID,其中主同步信道承载3个“组内ID”的其中之一,用所述3个主同步序列来区分,辅同步信道承载170个“ID组号”,用所述170个辅同步序列来区分。 The prior art synchronization channel also can carry a cell ID, wherein the primary synchronization channel carries one of "the group ID" of which three, with the three primary synchronization sequence to distinguish secondary synchronization channel carries 170 "ID group number ", with the 170 secondary synchronization sequences are distinguished. 这样现有技术中的同步信道能够承载510个小区ID。 Such prior art synchronization channel capable of carrying 510 cell ID. 小区ID是关于小区的信息之一,用于区分不同的小区。 It is one of information about a cell ID of the cell, for distinguishing different cells. 终端接收到上述同步序列后根据分析可知上述小区ID。 After receiving the above-described synchronization sequence according to the above-described analysis shows that cell ID.
