Abstract
In a wireless network there is a scheduling method in which a base station (BS) acquires information relevant to signal quality between the BS and each mobile terminal and reports to a scheduling apparatus. The scheduling apparatus selects a service BS for each terminal and determines a specific BS to compensate for interference; and may provide further controls to correspondingly transmit service data of the terminal to the service BS. The BS determines the serviced terminal and the terminal of which the interference is eliminated. When servicing the terminal on a time-frequency resource and eliminating the interference from other BS, the BS may only acquire channel state information of the terminal associated with the BS to the BS on the corresponding time-frequency resource and calculate a pre-coded matrix, so as to pre-code terminal service data from the service BS and generate downlink signals to be transmitted.
