关于6670的BCP中CRC问题



您好!

    我现在想做LTE的PDCCH的掩码操作,请问如何配METHOD2_ID????

    Bits          Field Name                Description

     31-0        METHOD2_ID            CRC method 2 ID. If the CRC format is not crc0, the CRC result is XORed with this value. For CRC formats shorter than 32                                                                bits,  the value should be placed in the MSBs (most-significant- bits) of this register. METHOD2_ID comes from the 3GPP                                                                  standard (3GPP 25.212 section 4.5.1.2 for FDD HSDPA) (3GPP 36.212 section 5.3.3.2 for LTE PDCCH).

                                                           Set to 0 for other standards.

比如我的RNTI为1掩码,我就使这个值为0x00000001吗???但是由这句话the value should be placed in the MSBs,我就配0x80000000???这两种我的试了,都不对。请问该怎么配???谢谢。。。。。。
