  • Patent number: 11902188
    Abstract: Systems and methods are described for selecting User Equipment(s) (UEs) for pairing in a cellular network. A channel orthogonality of one or more UEs located within a radio range of a first Access Node (AN) may be determined. The one or more UEs may be prioritized for Uplink (UL) Multi-User Multiple-Input-Multiple-Output (MU-MIMO) pairing when a channel orthogonality meets a set channel orthogonality condition. A second AN located within the radio range of the first AN may be detected. At least one of the prioritized UEs located within a radio range of the second AN may be selected for de-prioritization. The prioritized UEs may be paired to share a same set of resource blocks.

  • Patent number: 11849437
    Abstract: Disclosed are methods and systems to facilitate management of carriers to help ensure QoS for single-carrier UEs. In particular, a base station may serve one or more first user equipment devices (UEs) on just a first carrier. While doing so, the base station may determine that each of the one or more first UEs being served on just the first carrier is receiving threshold low quality of service from the base station on the first carrier. Responsive to this determining, the base station may (i) select one or more second UEs based on the one or more second UEs being served by the base station on both the first carrier and one or more other carriers and (ii) discontinue serving each selected second UE on the first carrier while continuing to serve each selected second UE on one or more other carriers.
