Abstract:
1. A method for common channel processing, comprising: generating a first set of common channel spectrum candidates according to location information of available sub-carriers and attribute information of the available sub-carriers retrieved from a first database of spectrum statuses; transmitting the first set of the common channel spectrum candidates to a terminal, so that the terminal determines a third set of common channel spectrum candidates according to the first set of the common channel spectrum candidates and a second set of common channel spectrum candidates generated by the terminal, wherein the third set of the common channel spectrum candidates is an intersection of the first set of the common channel spectrum candidates and the second set of the common channel spectrum candidates; and determining candidate sub-channels for common channels from the third set of the common channel spectrum candidates returned by the terminal, so as to generate and transmit a set of common channel spectrums to the terminal, wherein the set of the common channel spectrums comprises mapping relationship between the common channels and the spectrums of the candidate sub-channels for the common channels, wherein each set of the common channel spectrum candidates comprises location information of the candidate sub-channels, wherein the transmitting the first set of the common channel spectrum candidates to the terminal comprises: encoding the location information of the candidate sub-channels in the first set of the common channel spectrum candidates; and transmitting the encoded first set of the common channel spectrum candidates to the terminal in a Cyclic Code Shift Keying sequence modulation mode.
