摘要： 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.

摘要： When an access node is providing a UE with carrier-aggregation service on a PCell in combination with one or more SCells and the UE engages in a voice call including uplink voice communication on the PCell, the access node will determine that there is a threshold high level of IMD on the uplink resulting from concurrent downlink transmissions, and the access node will responsively swap the UE's PCell with one of the UE's one or more SCells. In a representative implementation, the decision to swap these carriers in the UE's connection could be based on a further determination that the level of IMD on the uplink of the SCell is not threshold high.

摘要： A method and a system for concurrently transmitting from an antenna a first sequence of data from a first access node and a second sequence of data from a second access node. An example method includes orthogonally encoding the first and second sequences, including encoding the first sequence with a first binary code to produce a first encoded sequence and encoding the second sequence with a second binary code to produce a second encoded sequence, combining the first encoded sequence and the second encoded sequence to produce a combined encoded sequence, and transmitting the combined encoded sequence from the antenna, with transmitting the combined encoded sequence from the antenna including engaging in a first transmission of the combined encoded sequence from the antenna and engaging in a second transmission of the combined encoded sequence from the same antenna with a phase delay compared with the first transmission.

摘要： A method and system for controlling transmission of signaling between a first access node and a second access node, in a system where the first access node and second access node are each configured to provide respective wireless coverage and service. An example method includes monitoring a total volume of data communication between the first access node and the second access node and, based at least on the monitoring, controlling a rate of periodic control signaling between the first access node and the second access node. In a dual-connectivity implementation, the method could apply, for instance, to control a rate at which the second access node transmits data-usage reports (e.g., second-RAT usage reports) to the first access node.

摘要： A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing a level of fading of the first air-interface connection with a level of fading of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

摘要： A method and system for controlling uplink transmit power of a UE when the UE is served concurrently on at least two air interfaces including a first air interface and a second air interface. An example method includes, iteratively for each successive given time interval of a continuum of equal-duration time intervals, (i) determining an actual average transmit power of the UE on the first air interface over the given time interval, (ii) using the determined actual average transmit power of the UE on the first air interface over the given time interval as a basis to set a maximum average transmit power of the UE for transmission on the second air interface in a respective subsequent time interval, and (iii) applying the set maximum average transmit power as a limitation on uplink transmit power of the UE for the transmission on the second air interface in the respective subsequent time interval.

摘要： A method and system for controlling maximum quantity of concurrent air-interface connections with an access node. An example method includes a tracking an aggregate rate of data flow served by the access node per time of day. And the example method includes, based on the tracking, determining what aggregate rate of data flow the access node tends to serve at a given time of day. Further, the example method includes, based on the determined aggregate rate of data that the access node tends to serve at the given time of day, (ii) determining a maximum limit on quantity of concurrent air-interface connections with the access node, and (iii) proactively configuring the access node to apply, at the given time of day, the determined maximum limit on quantity of concurrent air-interface connections with the access node.

摘要： A method and system to control configuration of a narrowband carrier within frequency bandwidth of a wideband carrier, where the frequency bandwidth of the wideband carrier defines a plurality of frequency segments. An example method includes selecting one of the frequency segments of the frequency bandwidth of the wideband carrier on which to define the narrowband carrier, with the selecting being based on the one frequency segment having a lowest level of noise among the plurality of frequency segments. And the example method may then further include, based on the selecting, configuring the narrowband carrier on the selected frequency segment of the frequency bandwidth of the wideband carrier rather than on another frequency segment of the plurality of frequency segments.

摘要： A method and system for controlling connectivity in a wireless communication system that includes a first cell and a second cell, when the first cell and the second cell are both candidates to serve a given user equipment device (UE). An example method includes determining a first Radio-Resource-Control (RRC)-connection-establishment failure rate of the first cell, where the first RRC-connection-establishment failure rate of the first cell is based on one or more instances of RRC-connection-establishment failure experienced in the first cell. And the method includes using at least the determined first RRC-connection-establishment failure rate of the first cell as a basis to control whether the given UE will be connected with the first cell or rather with the second cell. Further, in this method, the one or more instances of RRC-connection-establishment failure experienced in the first cell encompass RRC-connection-establishment failure experienced by one or more UEs other than the given UE.

摘要： A method and system for proactively reconfiguring communication to a user equipment device (UE) in anticipation the UE experiencing a coverage-throughput reduction when the UE is receiving streaming media. An example method includes (i) predicting, when the UE is receiving streaming media, that the UE is going to experience the coverage-throughput reduction and (ii) based at least in part on the predicting, proactively increasing a quality-of-service (QoS) level of a bearer through which the UE is receiving the streaming media, the proactively increasing occurring before the UE experiences the coverage-throughput reduction so that the QoS level is increased by when the UE experiences the coverage-throughput reduction.
