    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: A method and system for managing carriers on which a base station provides service to a user equipment device (UE), based on consideration of latency. A base station that is arranged to operate on a plurality of carriers may, while serving a UE on a set of one or more carriers of the plurality, select, from at least two other carriers of the plurality, an additional carrier to add to the set of one or more carriers on which the base station serves the UE, and may make the selection based a latency on the selected carrier. In response to selecting the additional carrier, the base station may add the selected carrier to the set of one or more carriers on which the base station serves the UE, and may then serve the UE on the set of one or more carriers including the selected carrier.

    Abstract: Disclosed is a method and system for controlling air interface communication in a wireless communication system that supports multiple TDD configurations. In a disclosed example, a base station's cell is initially configured to operate with a particular TDD configuration. The base station then detects a trigger to reduce uplink latency in the cell, such as by detecting a threshold number of devices being served with latency-sensitive communication such as voice-over-packet communication. And the base station responsively reconfigures the cell to operate with a different TDD configuration having lower uplink latency, where uplink latency of each TDD configuration is based average wait to uplink subframe of the TDD configuration.
