Abstract:
1. A method for user pairing and resource allocation, the method comprising steps of: a) performing a multiuser multi-input-multi-output (MU-MIMO) user pairing computer process to maximize an objective metric without common rank restriction; b) performing a rank balancing computer process to determine a uniform transmission user rank along all allocated resource blocks for each user; c) with the uniform transmission user rank fixed for the users, determining in a computer process optimal user pairing and allocation for the resource blocks for each user, determining the each user's sum rates over all the resource blocks allocated to this user from step a) and an objective metric having the same rank; fixing the rank of a selected one of the users as a rank that has the highest sum rate; when the selected one of the users has a rank-2, removing all the user's rank-1 resource block allocations; when the selected one of the users does not have a rank-2, retaining all the user's allocated resource blocks; and for the users that are not allocated on any of the resource blocks, setting their rank equal to one (1).
