Abstract

The present invention relates to a scheduling method, an apparatus and a base station apparatus. The method comprises the steps of: pre-pairing all candidate users on a channel to be scheduled, to get pre-pairing result corresponding to the channel to be scheduled; calculating a signal to interference plus noise power ratio of each pairing user of each pre-pairing group in the pre-pairing result, according to a channel quality information of the channel to be scheduled, a channel response message and a high interference indication information of cells interaction; according to the signal to interference plus noise power ratio of each pairing user of each pre-pairing group in the pre-pairing result, processing each pre-pairing group, to obtain all final suitable matched group, and calculating a weight value of all final suitable matched group that the maximum weight value corresponding final suitable matched group is a first pairing user of the channel to be scheduled; and scheduling the user by using the first pairing user of the channel to be scheduled. Accordingly, the present invention by using the interference information of cell interaction improves the cell average handling capacity and edge user handling capacity.

Description

technical field [0001] The present invention relates to the communication field, in particular to a scheduling method, device and base station. Background technique [0002] With the continuous development of wireless communication technologies, how to effectively improve the spectrum utilization rate of the entire network becomes more and more important. The traditional technology to improve spectrum utilization is Multiple Input Multiple Output (MIMO) technology. However, the distance between the antennas at the transmitting end and the receiving end restricts the correlation of the MIMO channel matrix itself and the improvement of the spatial spectrum efficiency. In addition, the terminal Factors such as size and cost also restrict the application of traditional MIMO technology. At present, a technology that is widely used is a Multi User-Multiple Input Multiple Output (MU-MIMO) technology, which can further improve spectrum utilization in the airspace dimension. [000...
