Abstract: A base station may use another base station's carrier-aggregation policy for a cell and carrier-aggregation capability information for a UE as a basis to control handover of the UE from the base station to the other base station. As one example, a first base station may receive, from a UE, a report that the UE has detected coverage of a target cell. The target cell may be provided by a second base station, and the first base station may determine whether the target cell can be aggregated with one or more other cells and whether the UE supports carrier aggregation. The first base station may then select a handover threshold based on the determination, and use the selected handover threshold as a basis to control handover of the UE from being served by the first base station to being served by the second base station.

Abstract: A mechanism for controlling secondary-coverage scanning for configuring dual-connectivity. A computing system establishes for a primary access node a scan list of secondary cells based on the primary access node having an X2 interface for each secondary cell and having received a threshold extent of B1 measurement reporting indicating threshold strong coverage of the secondary cell for configuration of dual-connectivity. Further, the computing system establishes for each secondary cell of the scan list a respective B1 measurement threshold based on evaluation of performance history of the secondary cell such as based on extent of secondary-access-node-addition failures involving the secondary cell and/or based on communication-quality metrics such as error rate or retransmission rate. The computing system then configures the primary access node to provide a B1 measurement object conveying the scan list with measurement thresholds.

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.

Abstract: When a base station is using multiple-input multiple-output (MIMO) communication defining multiple layers of communication to serve a user equipment device (UE) over an uplink channel, and the base station detects that its backhaul connection is threshold highly congested, the base station will responsively reduce the number of communication layers used to serve the UE over the uplink channel. In some examples, the base station could reduce the number of communication layers to a single layer, thereby transitioning from serving the UE using uplink MIMO communication to serving the UE using uplink single-input single-output (SISO) communication.

Abstract: A method and system to help manage air interface resources for communication between a user equipment device (UE) and a base station. As disclosed, a UE or base station detect a situation where a transport block that the base station would allocate to the UE would be too small to hold carry a packet that the UE would seek to transmit, and the UE and base station responsively switch to a mode of operation in which the UE will receive a multi-TTI transport block allocation rather than a single-TTI transport block allocation. Given a per-TTI limitation of available air interface resources, the allocation of a transport block spanning multiple TTIs may thus provide the UE with increased air interface capacity for transmission, thus optimally allowing the UE to transmit without a need for segmentation.

Abstract: A method and system to help control connectivity of a UE served with dual connectivity by a master node and a plurality of secondary nodes. An intermediary that is disposed between a core-network gateway system and the secondary nodes tracks data flow between the gateway system and the secondary nodes and provides the master node with a data-flow report, which the master node could use as a basis to trigger release of the UE's RRC connection, and/or to control addition or removal of one or more secondary nodes for the UE's dual-connectivity service.

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 method and system to help minimize communication latency. When data is to be transmitted from a transmitting entity to a receiving entity, the transmission will be scheduled to occur in a time interval that selected based on a consideration of the delay-sensitivity of the data and based on a HARQ delay associated with the selected time interval. For instance, if the data is particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that is selected based on the time interval having a relatively low associated HARQ delay, so as to help reduce the overall delay of the communication. Whereas, if the data is not particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that has a relatively high associated HARQ delay.

Abstract: Method and systems for assigning resources to user equipment devices (UEs) from a base station are disclosed. In accordance with the disclosure, the base station operates in a first mode in which the base station gives a UE a first scheduling priority level for resource assignment from the base station. The base station then makes a determination that a packet drop rate for the UE exceeds a threshold packet drop rate. Based on the determination, the base station switches from operating in the first mode to operating in a second mode in which the base station gives the UE a second scheduling priority level for resource assignment from the base station, where the second scheduling priority level is higher than the first scheduling priority level.

Abstract: Disclosed is a method and system for selectively muting default downlink transmission of particular reference signals in order to reduce interference experienced by user equipment devices (UEs) receiving user data. In scheduling transmission of a downlink resource block (RB), a base station may select a particular transmission mode (TM) that does not require transmission of the particular reference signal. The base station may also determine that no condition exists that requires default transmission of the particular reference signal during a time interval allocated for transmission of the RB and on sub-carrier frequencies allocated to the RB. With particular TM selected and the absence of other requirements for default transmission of the particular reference signal, the base station can then mute transmission of the particular reference signal during transmission of the downlink RB. The base station may also coordinate scheduling with a neighboring base station to achieve further interference reduction.
