Abstract:
1. An MU-MIMO scheduling method for allocating frequency- and space-divided resource blocks to users, comprising: allocating one or more resource blocks to a user with a maximum priority by determining the maximum priority used in allocation of resource blocks to users such that a priority based on reception Signal to Interference and Noise power Ratios for each resource block is used for a first multiple MIMO layer, and a priority based on corrected Signal to Interference and Noise power Ratios is used for the second and onward multiple MIMO layers; computing a corrected Signal to Interference and Noise power Ratio of an unselected user for resource blocks in the multiple MIMO layer next to that of the allocated resource blocks; computing a priority represented by a function of the corrected Signal to Interference and Noise power Ratio; and allocating resource blocks to a next user by using priorities for unallocated resource blocks including the resource blocks for which the priority has been computed.
