    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 are methods and systems to facilitate handover of a UE away from a primary carrier of a base station, despite a primary carrier having a channel quality that is at or above a channel quality threshold of the primary carrier. In particular, a wireless communication system may serve the UE with carrier aggregation service using (i) a first carrier as a primary carrier for the UE and (ii) a second carrier as a secondary carrier for the UE. During the serving, while a channel quality of the primary carrier is at or above a first threshold quality, the system may make a determination that a channel quality of the secondary carrier is below a second threshold quality. In response to at least making the determination, the system may carry out a handover of the UE from the primary carrier of the first base station to another carrier.

    Abstract: A wireless network receives one or more data segments transmitted by a wireless communication device (WCD) in or more transmission time intervals (TTIs), estimates a size of a next data segment to be transmitted by the WCD based at least in part on sizes of the one or more data segments transmitted by the WCD, and allocates a quantity of uplink resources (e.g., a number of physical resource blocks) to the WCD for use in one or more subsequent TTIs (e.g., TTIs used for TTI bundling) based at least in part on the estimated size of the next data segment. The network may refer to an algorithm, such as a Transmission Control Protocol (TCP) congestion control algorithm, that specifies how sizes of successive data segments increase over time to predict the size of the next data segment based on the sizes of the one or more data segments.
