Abstract:
1. A method for enhancing performance for a wireless communication environment, comprising: determining channel information for user devices; assigning the user devices to at least one beam from a predetermined set of beams, the set of beams comprising at least one narrow beam and a wide beam, wherein assigning the user devices to the at least one narrow beam comprises scheduling a first user device using a spatial division multiplexing (SDM) scheduling technique and scheduling a second user device using a multiple-in multiple-out (MIMO) scheduling technique, and wherein the at least one narrow beam and the wide beam are separate beams, reassigning at least one user device from a narrow beam to the wide beam if channel quality information is lower than a threshold value, wherein the at least one narrow beam comprises a first cluster of narrow beams having a dominant direction and a second cluster of narrow beams having a dominant direction, wherein the dominant direction of the first cluster is different from the dominant direction of the second cluster; and scheduling the first and second user devices simultaneously, using said SDM scheduling technique and said MIMO scheduling technique, by employing the first cluster of narrow beams and the second cluster of narrow beams.
