Abstract

The embodiment of the present invention discloses a scheduling method for multi-user multiple-input multiple-output MU-MIMO, which includes: performing optimal pairing of candidate users on the first to nth resources to be allocated, and obtaining the first to nth resources respectively The optimal user pairing of resources to be allocated, n is a positive integer; combine the optimal user pairings to obtain all user pairing groups composed of the optimal user pairings, and guarantee to obtain when combining the optimal user pairings In each user pairing group, the same user only exists in one optimal user pairing; the 1st to nth resources to be allocated are assigned to the optimal user pairing in the user pairing group with the largest number of optimal user pairings . The embodiment of the invention also discloses a scheduling device. By adopting the invention, the computational complexity in the scheduling process can be reduced, and the frequency spectrum utilization rate can be improved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a scheduling method and device for MU-MIMO (Multi-User Multiple Input Multiple Output, multi-user multiple input multiple output). Background technique [0002] With the continuous development of wireless communication technology, the industry and academia continue to improve the spectrum utilization rate of the entire network from the dimensions of time domain, frequency domain, air domain or code domain, and tap potential gains. Among them, the MIMO technology is a method to effectively improve spectrum utilization without increasing the transmit power of the transmitter. However, the antenna spacing between the transmitting end and the receiving end restricts the correlation of the MIMO resource matrix itself and the improvement of the spatial spectrum efficiency, and factors such as the size and cost of the user terminal itself also restrict the application of MIMO...
