    摘要： A signal transmission apparatus in a communication system, includes: a first IFFT unit for generating a first signal by performing inverse fast Fourier transform on a first communication service signal corresponding to a first communication scheme; a first CP inserter for generating a second signal by inserting a first cyclic prefix having a length corresponding to the first communication scheme into the first signal; a second IFFT unit for generating a third signal by performing inverse fast Fourier transform on a second communication service signal corresponding to a second communication scheme; a second cyclic prefix inserter for generating a fourth signal by inserting a second cyclic prefix having a length corresponding to the second communication scheme into the third signal; and a transmission unit for multiplexing the second signal and the fourth signal and transmitting the multiplexed signals.

    摘要： A method and an apparatus maximize the capacity of a wireless communication network by taking into consideration inter-cell interference coordination. A home cell's capacity sensitivity to interference is calculated. At least one neighbor cell's capacity sensitivity to interference is collected. And at least one UE located in the home cell is scheduled based on the home cell's capacity sensitivity and the neighbor cell's capacity sensitivity. Accordingly, it is possible to achieve power and allocation control to maximize the capacity of the overall network including neighbor cells increase the system capacity in a cellular system in which inter-cell interference is large, and adaptively perform a UE scheduling in real time to changing distribution of UEs because information on a change in the capacity of each cell is shared by periods.
