    Abstract: According to aspects of the disclosure, a method and system are provided for managing signaling in a wireless communication network. In some aspects, a base station serves a user equipment device (UE) over an air interface connection between the base station and the UE, and a bearer extends between the UE and a gateway. An example method may involve determining a quality of service (QoS) level of the bearer, and responsively selecting a channel state information (CSI) reporting rate based on the determined QoS level. Further, in some aspects, responsive to the selection of the CSI reporting rate, the method may involve causing the UE to periodically report CSI to the base station according to the selected CSI reporting rate. The method may be performed, in whole or in part, by the UE, the base station, and/or another entity in the wireless communication system.

    Abstract: A method and system for controlling how many carriers to aggregate together for carrier-aggregation service of a UE. A base station could take into account how many MIMO layers a UE would support respectively for each of various candidate quantities of carriers, and the base station could select the candidate quantity of carriers that would result in use of a highest aggregate total number of MIMO layers. Further, the selection could involve mapping UE-reported rank to a quantity of carriers, with the rank being inversely proportional to the selected quantity of carriers. The base station could then configure carrier-aggregation service of the UE with the selected quantity of carriers.

    Abstract: A method and system to help manage resources in a fallback scenario is disclosed. A first network may be configured to serve user equipment devices (UEs) according to a first protocol and a second network may be configured to serve UEs according to a second protocol. The method may involve the first network serving a UE, where serving the UE includes allocating at least one resource to the UE. The method may also involve, after the UE has transitioned from being served by the first network to being served by the second network for a circuit-switched-fallback call, (i) if the UE completes call setup, the first network releasing the resources, but (ii) if the UE does not complete call setup, the first network using the allocated resources to serve the UE after the UE transitions back to being served by the first network.

    Abstract: Disclosed are methods and systems for setting a timeout period. In particular, a BS may have data storage defining a buffer. Also, the BS may be configured to (i) provide an air interface through which the BS serves UEs, (ii) buffer data packets destined to individual UEs, and (iii) apply a buffer timeout process according to which the BS drops a data packet from the buffer in response to that data packet being in the buffer for a timeout period. As such, the BS may make a determination that a served UE is a relay-UE that provides wireless backhaul connectivity for a relay-BS, and may set the timeout period based on the determination. When the BS then applies the buffer timeout process, the BS drops a data packet from the buffer in response to that data packet being in the buffer for the timeout period set based on the determination.

    Abstract: Disclosed is a method and system for channel selection. As disclosed, a wireless communication system includes a base station that is configured to operate on a plurality of channels, each having a respective level of port-to-port isolation. The system determines a measure of quality of an air interface between the base station and a user equipment device (UE) served by the base station. The system then selects, from the plurality of channels, a channel on which the base station should serve the UE, where the selecting is based at least in part on (i) the determined measure of quality of the air interface between the base station and the UE and (ii) a correlation between the determined measure of quality of the air interface and the respective level of port-to-port isolation of the channel. Upon the selection, the base station serves the UE on the selected channel.

    Abstract: One embodiment takes the form of a method carried out by a handover source while the handover source is serving a UE with communication service at a quality of service level. The method includes the handover source transmitting, to a first handover target, a first handover request including an indication of the quality of service level. Next, in response to the transmitted first handover request, the handover source receives from the first handover target a response indicating that the first handover target does not support the quality of service level, but specifying a second handover target that supports the quality of service level. The handover source may then transmit to the specified second handover target a second handover request seeking handover of the UE from being served by the handover source to being served by the second handover target.
