  • Patent number: 10952270
    Abstract: In an arrangement where an access node (e.g., a Node-B) is used in dual-connectivity service of UEs that are served by other access nodes, resources of the access node could be dynamically allocated to the UEs based at least on respective priorities designated for the other access nodes. For instance, each other access node could be prioritized based on its type, such as whether it is a macro access node, a small-cell access node, an indoor access node, an access node for a special event, or a access node for dedicated service, among other possibilities, and allocation of resources of the jointly-used access node could be defined based on these priorities, giving higher resource-allocation priority to UEs that are served by a higher priority other access node and giving lower resource-allocation priority to UEs that are served by a lower priority other access node.

    Abstract: A cell site that has multiple first-RAT carriers will monitor a capacity demand respectively of each first-RAT carrier, with capacity demand representing an extent to which adding more service capacity could be useful in view of the state of service on the 4G carrier. Further, the cell site will dynamically allocate resources of a second-RAT carrier for use in dual-connectivity service of UEs served on various ones of the first-RAT carriers, with the allocation being based on the capacity demands of the various primary-RAT carriers. For instance, if a first first-RAT carrier has a higher capacity demand than a second first-RAT carrier, then the cell site could allocate a more resources of the secondary-RAT carrier for use in dual-connectivity service of UEs served on the first first-RAT carrier than for use in dual-connectivity service of UEs served on the second first-RAT carrier.

  • Patent number: 10862553
    Abstract: When a base station groups a given user equipment device (UE) together with one or more other UEs for multi-user multiple-input-multiple-output (MU-MIMO) service, the base station will predict a level of RF correlation between the given UE and the one or more other UEs of the group (e.g., based angular separation between beam direction of the UE and beam direction of each of the one or more other UEs). And the base station will use that predicted level of RF correlation as a basis to adjust a modulation and coding scheme (MCS) that the base station and the given UE will use for data communication with each other, so as to help improve data communication between the base station and the given UE in the presence of the predicted RF correlation.
