摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Systems and methods are described for mitigating interference from neighbors. Interference may be monitored at a first access node, wherein the monitoring includes detecting an interference pattern over at least two monitored subframes. The interference pattern may be analyzed to identify one or more interference sources, wherein a first interference pattern indicates interference caused by a neighboring access node and a second interference pattern indicates interference caused by one or more wireless devices communicating with a neighboring access node. The identified interference sources may be instructed to adjust transmissions based on the monitored interference.

摘要： Performing carrier aggregation for high-powered wireless devices that may cause interference to other wireless devices includes determining that a wireless device attached to an access node is assigned to a high power class and capable of operating in a carrier aggregation mode, initiating the carrier aggregation mode for the wireless device, and instructing the access node to utilize a frequency-division-duplexing (FDD) carrier deployed by the access node as a primary carrier for the wireless device. A handover of the wireless device to the FDD carrier may be triggered by a threshold level of interference caused by uplink transmissions from the wireless device when operating in the high-powered transmission mode on a TDD carrier.
