[0090] In the second embodiment, it is assumed that some resource blocks or resource block pairs or frequency resources are evenly extracted within the entire system bandwidth, and the explicit extraction method is adopted, and the corresponding extraction information is carried in broadcast information or system information or dedicated information or RRC signaling. The details are shown in Table 1:
[0091] Number of system bandwidth resource blocks
Extract information bits
p kinds of starting positions
i is the interval size

i＝2 x4
[0092] Table 1
[0093] In Table 1, x1, x2, x3, and x4 are any positive integers. When x1, x2, x3, and x4 are different, it means that different system bandwidths are extracted at different intervals; when x1, x2, x3, an...

[0103] In the third embodiment, assuming that some resource blocks or resource block pairs or frequency resources are uniformly extracted within the entire system bandwidth, explicit extraction is used at this time, and the corresponding extraction information is carried in broadcast information or system information or dedicated information or RRC signaling. The details are shown in Table 2:
[0104] Number of system bandwidth resource blocks
Extract information bits
p kinds of starting positions
q types of interval size

[0105] Table 2
[0106] In Table 2, x1, x2, x3, x4, y1, y2, y3, y4 are any positive integers; "2 x " means "x" power in base "2"; "2y" means "y" power in base "2". Preferably, or where N RB Indicates the number of resource block...

[0136] In the eighth embodiment, the extraction is performed according to the second embodiment to the seventh embodiment. After the resource blocks or resource block pairs or frequency resources are renumbered, at this time, the corresponding resource allocation method can be the same as that corresponding to the shared channel in the LTE system. The resource allocation method is the same, or the resource allocation method of the bitmap bitmap is adopted.
[0137] When using the same method as the resource allocation method corresponding to the shared channel in the LTE system, the resource allocation method corresponding to the resource allocation field in the first embodiment can be used;
[0138] When the bitmap resource allocation method is adopted, that is, one bit corresponds to one frequency resource, as in the second embodiment, the system bandwidth is 25 resource blocks, n=(0 1 2...24), according to the second embodiment Extraction, then there are i=2, j=1, m={(n-1) / ...
