Abstract: When a UE is served with dual-connectivity by a master node (MN) over master connection on a first radio access technology (RAT) and a secondary node (SN) over a secondary connection on a second RAT and where the UE is engaged in a voice call over the master connection, an entity detects that quality of the UE's master connection has become threshold poor and responsively carries out a sequence of operations including (i) releasing the UE's secondary connection with the SN so as to transition the UE from dual-connectivity to standalone-connectivity served by the MN, and (ii) then transferring the UE's voice call from being served by the MN on the first RAT to instead being served by a tertiary node (TN) on a third RAT.

Abstract: When a serving base station encounters a trigger for handover of a UE to a target base station, the serving base station will responsively predict whether, before the serving base station would direct the UE to handover to the target base station, an inactivity timer for the UE will expire, and the serving base station will then control the handover based on that prediction. For instance, responsive to the predicting being that the inactivity timer will expire before the serving base station would send a handover command message to the UE, the serving base station could forgo engaging in handover-preparation signaling with the target base station for the handover, instead allowing the UE to transition to idle mode upon expiration of the timer, at which point the UE could then engage in idle-mode handover to the target base station.

Abstract: Disclosed is a method and system that may help control when a network will request (and receive) a remaining battery energy level report from a UE. Per the disclosure, a network that has an established radio-link-layer connection with the UE could track an amount of time in which the UE operates in a radio-link-layer connected mode. The network could then determine whether the amount of time in which the UE has operated in the radio-link-layer connected mode has exceeded a predetermined threshold amount of time. And responsive to determining that the amount of time in which the UE has operated in the radio-link-layer connected mode has exceeded the threshold amount of time, the network could cause the UE to report to the network the remaining battery energy level of the UE.

Abstract: A method and system to manage coordinated transmission of data in a wireless communication system. When a serving base station receives data of a particular class for transmission to a user equipment device (UE), the serving base station transmits the received data to the UE and sends a proper subset of the received data to a neighboring base station for the neighboring base station to also transmit to the UE optimally concurrently with the serving base station's transmission of the proper subset. To help comply with a policy in place at the neighboring base station, the serving base station decides how much of the received data to send to the neighboring base station as the proper subset by (i) determining what scheduling weight the neighboring base station is set to apply for data of the particular class and (ii) applying that determined scheduling weight to the received data.

Abstract: Disclosed are methods and systems to facilitate variation of timer duration. In particular, a relay node (RN) may be configured to be served by a base station (BS) over a relay backhaul air interface and may be configured to serve user equipment devices (UEs) over a relay coverage air interface. Also, the RN may be configured (i) to detect when a threshold error in communication occurs on the relay backhaul air interface, (ii) in response to detecting the threshold error in communication, to start a timer that runs for a timer duration, and (iii) to respond to expiration of the timer duration by engaging in management of the relay backhaul air interface. With these arrangements, the RN may determine a count of how many UEs are being served by the RN over the relay coverage air interface and may set the timer duration based on the determined count of UEs.

Abstract: A method and system to assign a contention-free access resource 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 involves the first network detecting an attempt to set up a circuit-switched-fallback (CSFB) call between (i) a UE served by the first network and (ii) a remote party, where the CSFB call is to be served by the second network to which the UE would transition to be served with the CSFB call. The method further involves, in response to detecting the attempt to set up the CSFB call, the first network assigning a contention-free access resource to the UE, so as to allow a contention-free access request by the UE to the first network.

Abstract: A radio access network may determine that a hybrid automatic repeat request (HARQ) transmission schedule of a wireless air interface defined by the RAN includes time-division-multiplexed slots that are subject to HARQ acknowledgment bundling and time-division-multiplexed slots that are not subject to HARQ acknowledgment bundling. The RAN may assign, to relay base stations served by the RAN, time-division-multiplexed slots of the wireless air interface that are not subject to HARQ acknowledgment bundling. The RAN may also assign, to non-relay wireless communication devices (WCDs) served by the RAN, time-division-multiplexed slots of the wireless air interface that are subject to HARQ acknowledgment bundling. The RAN may transmit, over the air interface, HARQ subpackets according to the transmission schedule and assignments of time-division-multiplexed slots.

Abstract: According to aspects of the disclosure, a method and system are provided for managing cell selection in a wireless communication network. In accordance with this disclosure, each cell in a radio access network (RAN) broadcasts a respective carrier-aggregation policy of the cell on its air interface. A UE engaging in a cell selection process reads the respective carrier-aggregation policy of each cell under consideration and selects a cell on which to attach based at least in part on the respective carrier-aggregation policies of the cells. The UE can then attach to the selected cell so that the selected cell can then serve the UE.

Abstract: A method for controlling a UE situated in both a coverage area of a first base station and a coverage area of a second base station involves detecting that the UE is ping-ponging between being served by the first base station and being served by the second base station and determining that the second base station is a relay base station. Further, the method involves, responsive to detecting the ping-ponging and determining that the second base station is a relay base station, (a) determining a carrier on which the first base station provides service and on which the second base station does not provide service, and (b) based on the first base station providing service on the determined carrier and the second base station not providing service on the determined carrier, causing the UE to be served by the first base station on the determined carrier.
