Abstract

The invention relates to a scheduling method, device and base station. The method includes: pre-pairing all candidate users on the channel to be scheduled to obtain a pre-pairing result corresponding to the channel to be scheduled; according to the channel quality information of the channel to be scheduled, channel response information and high interference indication information interacted between cells, Calculate the SINR of each paired user in each pre-paired group in the pre-paired result; according to the SINR of each paired user in each pre-paired group in the pre-paired result, after processing each pre-paired group, get All final suitable pairing groups, and calculate the weights of all final suitable pairing groups and determine the final suitable pairing group corresponding to the maximum weight as the first pairing user of the channel to be scheduled; use the first pairing user of all channels to be scheduled for user scheduling. Therefore, the present invention realizes the use of inter-cell interaction interference information, and improves the average throughput of the cell and the throughput of the edge user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a user scheduling method and device. 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. [0003] The me...
