Abstract: Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.

Abstract: Data identifying a plurality of wireless coverage areas in a region may be obtained. The data may identify geographic locations of the wireless coverage areas. Possibly based on the data, the wireless coverage areas may be arranged into a plurality of mutually exclusive tracking area groups. Each of the tracking area groups may include multiple wireless coverage areas and may be identified by respective unique tracking area identifiers. The tracking area groups may form a geographically-defined sequence across the region. A numerical sequence of wireless coverage area identifiers may be assigned to the wireless coverage areas in the region, one wireless coverage area identifier per wireless coverage area. The wireless coverage areas of the tracking area groups may be provisioned to use the assigned wireless coverage area identifiers.

Abstract: A computing device may obtain n values of a first performance indicator of a network and n values of a second performance indicator of the network. The ith value of the first performance indicator may be based on a measurement of the first performance indicator within an ith time period, and the ith value of the second performance indicator may be based on a measurement of the second performance indicator within the ith time period. A set of aggregate weighted rank values of the first and second performance indicators may be determined. A jth entry in the set of aggregate weighted rank values may be selected, and the jth value of the first performance indicator and the jth value of the second performance indicator may be used to provision the network.

Abstract: A base station or an associated control entity determines when base station's air interface is threshold highly loaded or is predicted to be threshold highly loaded, and the base station responsively reduces the number of transmit antennas that the base station uses. Further, the base station or associated control entity could determine when the base station's air interface is no longer actually or predicted to be threshold highly loaded, and the base station could responsively increase the number of transmit antennas that the base station uses, such as by reverting to use a default number of antennas. Reducing the number of transmit antennas that the base station uses when its air interface is threshold highly loaded may help to increase air-interface capacity by reducing resource consumption from transmission of reference signals associated with the transmit antennas.

Abstract: A method and system for controlling air-interface connectivity of a user equipment device (UE). A computing system detects, when the UE has dual connectivity including a first air-interface connection with a first access node and a second air-interface connection with a second access node, and when the first air-interface connection is defined on a first carrier, that the UE is moving toward a geographic area where UEs that were served by the first access node on the first carrier as part of dual connectivity lost their dual connectivity due to their having insufficient aggregate dual-connectivity throughput. And based at least on the detecting, the computing system reconfigures the first air-interface connection of the UE's dual connectivity to be defined on a lower-frequency second carrier, to help avoid having the UE lose its dual connectivity.

Abstract: A method and system for controlling wireless service of a user equipment device (UE) by an access node. The access node serves the UE with uplink carrier-aggregation over a connection encompassing multiple uplink channels including a primary uplink channel (uplink PCell) and a secondary uplink channel (uplink SCell). Further, the access node dynamically sets a channel-quality threshold applicable to control when to deconfigure the uplink SCell from service of the UE, with the dynamically setting of the channel-quality threshold including setting the channel-quality threshold to a value selected based on one or more operational circumstances of the UE, such as whether the UE is engaged in uplink heavy or rather uplink light communication. And the access node applies the dynamically set channel-quality threshold to control when to deconfigure the uplink SCell from service of the UE.

Abstract: When a UE is served by a first radio access network (RAN) and is engaged in a voice call such as a VoIP call, a determination will be made that the UE is at an edge of coverage (e.g., threshold poor coverage) of the first RAN and that there is no other adjacent coverage of the first RAN that could support the voice call. In response, signaling will cause a second RAN to page the UE via the first RAN so as to cause the UE to transition from being served by the first RAN to being served by the second RAN. More generally, when a UE has poor coverage of its serving RAN, another RAN will pull the UE to the second RAN by paging the UE to trigger transition of the UE from to the second RAN.

Abstract: Methods and systems for controlling service by a base station when the base station is serving both a first UE without carrier aggregation and a plurality of second UEs with carrier aggregation. As a basis for invoking carrier aggregation service for the first UE, the base station selects one of the second UEs to transition from being served by the base station with carrier aggregation to being served by the base station without carrier aggregation. The base station makes such a selection based at least in part on a modulation and coding scheme that the base station uses to serve the selected one of the second UEs. The base station transitions from serving the selected second UE with carrier aggregation to serving the selected second UE without carrier aggregation. And the base station transitions from serving the first UE without carrier aggregation to serving the first UE with carrier aggregation.

Abstract: Methods and systems to help manage wireless communication with UEs in a manner that takes into account an extent of TTI bundling on a given carrier frequency. When a base station is serving a threshold high number of TTI-bundling-UEs on a first carrier frequency, the base station will reduce the number of TTI-bundling-UEs on the first carrier frequency by offloading one or more of the TTI-bundling-UEs from the first carrier frequency to a second carrier frequency. Further, to avoid increasing the number of TTI-bundling-UEs served on the first carrier frequency, when the base station detects a trigger event for enabling TTI bundling for an additional UE served on the first carrier frequency, the base station will offload the additional UE from the first carrier frequency to the second carrier frequency.
