Claim of US Patent No. 10,716,124

1. A method for controlling service over an air interface in a wireless communication system, the method comprising:serving, by a base station, a plurality of user equipment devices (UEs) over the air interface, wherein each UE is located at a respective geographic location;
determining by the base station to group at least two of the UEs together with each other as a Multi-User Multiple-Input-Multiple-Output (MU-MIMO) group for MU-MIMO service over the air interface, wherein the determining is based on the geographic locations of the at least two UEs being at least a threshold Euclidian distance apart from each other and additionally on a beam direction from the base station to each UE of the at least two UEs being at least threshold different than a beam direction from the base station to each other UE of the at least two UEs; and
based on the determining, grouping by the base station the at least two UEs together with each other as the MU-MIMO group for MU-MIMO service over the air interface,
wherein determining to group the at least two UEs together with each other for MU-MIMO service with the determining being based on the geographic locations of the at least two UEs being at least the threshold Euclidian distance apart from each other and additionally on the beam direction from the base station to each UE of the at least two UEs being at least threshold different than the beam direction from the base station to each other UE of the at least two UEs comprises (i) making a first determination that the geographic locations of the at least two UEs are at least the threshold Euclidian distance apart from each other, (ii) making a second determination that the beam direction from the base station to each UE of the at least two UEs is at least threshold different than the beam direction from the base station to each other UE of the at least two UEs, and (iii) based at least on a combination of the first determination and the second determination, determining to group the at least two UEs together with each other for MU-MIMO service.
