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 that encompasses 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 (e.g., an RSRP 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 iteratively adjusting the channel-quality threshold based on uplink spectral efficiency of the access node. 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: A method and system for controlling uplink air-interface communication over an air interface from a given user equipment device (UE) to the access node, where the uplink air-interface communication normally operates with a modulation order corresponding with a most recently determined channel quality of the given UE. An example method includes (i) detecting at least a threshold high rate of uplink voice muting on the air interface, and (ii) responsive to at least the detecting of the threshold high rate of uplink voice muting on the air interface, suppressing the modulation order used for the uplink air-interface communication from the given UE to the access node over the air interface.

Abstract: When a user equipment device (UE) is served with standalone connectivity by a first access node on a first carrier, the first access node could detect a trigger for transitioning the UE from the standalone connectivity to dual connectivity. In response to at least the trigger, the first access node could then (i) transition the UE from the first carrier to a second carrier selected based on the second carrier being lower in frequency than the first carrier, so as to help facilitate quality communication in the dual connectivity service, and then (ii) transition the UE from the standalone connectivity to the dual connectivity.

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: 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.

Abstract: Disclosed herein is a method and corresponding apparatus to help manage wireless communication between a base station and a device served by the base. In accordance with the disclosure, when a base station transitions from serving the device on just a first carrier to serving the device on a combination of the first carrier and a second carrier, the base station will responsively take action to improve downlink communication to the device on the first carrier. In particular, the base station will respond to the occurrence of that transition by starting to beamform downlink transmission to the device on the first carrier.

Abstract: A method and system for controlling wireless communication over an air interface between a base station and a user equipment device (UE) served by the base station. In examples, the base station is configured to use a particular modulation and coding scheme (MCS) to transmit downlink control signals over the air interface to the UE without the base station beamforming the downlink control signals to the UE. Responsive to the base station determining that the UE is experiencing threshold poor RF conditions on the air interface, the base station reconfigures itself to beamform downlink control signals to the UE. And, given that the base station is reconfigured to beamform downlink control signals to the UE, the base station further reconfigures itself to use a higher-order MCS to transmit downlink control signals to the UE.

Abstract: In a long term evolution (LTE) network, coordinated multipoint (CoMP) and transmission time interval (TTI) bundling can both help to improve uplink communications, but both can also place a burden on network resource. Further, since both utilize redundancy to improve uplink communications, albeit in different ways, use of CoMP and TTI bundling may be considered unnecessary. Accordingly, example methods and systems are provided that may help to balance the application of TTI bundling and CoMP.
