Claim Text:
1. A method for dynamic spectrum management of an apparatus which comprises at least a processor executing program codes stored in a memory, which configure the apparatus to perform functions, comprising: determining, by a processor a reusable spectrum for one of multiple cell links in a network according to co-frequency indication information, wherein the co-frequency indication information comprises a co-frequency indication matrix, and wherein the co-frequency indication information is used to indicate reusable levels of spectrums of other cell links for each cell link in the multiple cell links; updating, by the processor, a spectrum configuration of the one of the multiple cell links by using the reusable spectrum of the one of the multiple cell links; obtaining, by the processor, a link state of each cell link in the multiple cell links, propagation attenuation parameters, and a topology of the network; and generating or updating, by the processor, the co-frequency indication matrix according to the link state of each cell link in the multiple cell links, the propagation attenuation parameters, and the topology of the network; wherein: each element of the co-frequency indication matrix indicates a reusable level of a spectrum of another cell link for one cell link in the multiple cell links; wherein: the link state comprises: a load of the cell link, interference strength, and transmit power of a base station of the cell link; the reusable level of the spectrum of the other cell link for the one cell link in the multiple cell links comprises: wherein the determining of the reusable spectrum for the one of the multiple cell links in the network according to the co-frequency indication information comprises: wherein: the load after the spectrum of the spectrum of the other cell link is reused by the one cell link is indicated by the following formula: where the one cell link is cell link i, the other cell link is cell link j,
