Abstract: When a user equipment device (UE) is served with standalone connectivity by a first access node on a first carrier, the first access node could detect a trigger for transitioning the UE from the standalone connectivity to dual connectivity. In response to at least the trigger, the first access node could then (i) transition the UE from the first carrier to a second carrier selected based on the second carrier being lower in frequency than the first carrier, so as to help facilitate quality communication in the dual connectivity service, and then (ii) transition the UE from the standalone connectivity to the dual connectivity.

Abstract: According to aspects of the disclosure, a method and system are provided for managing signaling in a wireless communication network. In accordance with the disclosure, a base station radiates to provide an antenna radiation pattern defining a coverage area, and the base station serves a UE in the coverage area defined by the antenna radiation pattern. The base station also selects, based on the determined antenna radiation pattern, a CSI reporting rate. Responsive to the selection of the CSI reporting rate, the base station causes the UE to periodically report CSI to the base station according to the selected CSI reporting rate.

Abstract: A mechanism to control transmission by a base station, which may help to control interference on an adjacent frequency. The base station is configured to operate on a first frequency and is equipped with a number of antennas enabled for transmission on the first frequency. Upon detecting of a trigger for reducing potential interference on the adjacent frequency, the base station reduces the number of its antennas that are enabled for transmission on the first carrier, which may reduce the overall energy of the base station's transmission and may thereby reduce interference on the adjacent frequency. In an example implementation, the base station could disable a proper subset of its antennas from use for transmission on the first frequency, while leaving a remainder of its antennas enabled for transmission on the first frequency.

Abstract: A method and system to help control CoMP service in a V-RAN arrangement. The load on a cell site's fronthaul network interface between the cell site's RRH and the cell site's BBU is determined. And in response to detecting that the fronthaul load is threshold high, a limit will be imposed on application of CoMP service involving the cell site. For example, in response to detecting that the cell site's fronthaul network interface is threshold highly loaded, (i) the cell site could be made to use decentralized joint processing rather than centralized joint processing, (ii) a lower coverage strength threshold could be imposed as a basis to trigger CoMP service involving the cell site, and/or (iii) the quantity of uplink communication that is subject to CoMP service involving the cell site could be limited.

Abstract: In a wireless communication system where a wireless access network includes a base station providing coverage in which to serve devices and where the wireless access network provides connectivity with an Internet Multimedia Subsystem (IMS), a method and system to help manage network resources by dynamically controlling when setup of a dedicated bearer will be invoked for a packet-based call placed by a device served by the base station. If the base station is lightly loaded, then setup of dedicated bearer could be invoked before the called party answers the call. Whereas, if the base station is heavily loaded, then setup of the dedicated bearer could be invoked if and when the called party has answered.

Abstract: A base station configures a TDD carrier to have a first TDD configuration for serving of a first UE and to have a second TDD configuration for serving of a second UE concurrently with the serving of the first UE. Such configuring causes the second UE to engage in an uplink communication in at least one subframe in which the first UE engages in a downlink communication, which could lead to interference issues. Therefore, the base station causes the second UE to apply uplink beamforming, so as to help minimize interference resulting from the second UE engaging in the uplink communication in the at least one subframe in which the first UE engages in the downlink communication.

Abstract: Disclosed are methods and systems for configuring service of a user equipment device (UE). When the UE has dual-connectivity service, such as EN-DC service, poor quality on one of the UE's air-interface connections could result in transition of the UE to single-connectivity service. To address technological issues that may arise in this process, one of the UE's serving Node-Bs (NBs) could control teardown of an access bearer homed to the other of the UE's serving NBs. Further or alternatively, a control-plane signaling path that is homed to one of the UE's serving NBs could be replaced with a control-plane signaling path instead homed to the other of the UE's serving NBs. In addition, in appropriate circumstances, when such reconfiguration occurs, service of the UE could be switched from one core network to another.

Abstract: When a base station that does not support downlink beamforming is serving a UE and a guaranteed-bit-rate (GBR) bearer is established for the UE, the base station will detect the establishment of the GBR bearer for the UE and will responsively trigger handover of the UE to another base station selected based on the other base station supporting downlink beamforming. With this process, handing the UE over to a base station that supports downlink beamforming may thereby help to ensure successful transmission to the UE at the GBR associated with the bearer.

Abstract: A method and system to help minimize communication latency. When data is to be transmitted from a transmitting entity to a receiving entity, the transmission will be scheduled to occur in a time interval that selected based on a consideration of the delay-sensitivity of the data and based on a HARQ delay associated with the selected time interval. For instance, if the data is particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that is selected based on the time interval having a relatively low associated HARQ delay, so as to help reduce the overall delay of the communication. Whereas, if the data is not particularly delay-sensitive, then the transmission could be scheduled to occur in a time interval that has a relatively high associated HARQ delay.

Abstract: When a base station is going to offload a UE from a carrier and is faced with a choice of whether to transition the UE from that carrier to a first carrier or rather to a second carrier, the base station will select the first carrier as the target carrier based at least on a determination that the first carrier has higher insertion loss than the second carrier. In addition, to help offset service of the UE on the high-insertion-loss carrier, the base station may block other UEs from being served on the first carrier.
