    摘要: When a first base station is serving a UE with carrier-aggregation on a combination of carriers including a first carrier as PCC of the carrier-aggregation service and a second carrier as an SCC of the carrier-aggregation service, the first base station could predict that the UE will hand over from being connected with the first base station to being connected with an adjacent second base station on the second carrier. In response to this prediction, the first base station could then reconfigure the UE's carrier aggregation service by swapping the UE's PCC and SCC so that the second carrier would become the PCC of the carrier-aggregation service and the first carrier would become an SCC of the carrier-aggregation service. This reconfiguration of the UE's carrier-aggregation service could thereby facilitate carrier continuity as the UE engages in the predicted handover.

    摘要: When a first node is considering setup of dual-connectivity service for a UE, the first node will take into consideration an uplink power headroom level of one or more candidate second nodes (representing uplink power headroom of one or more UEs served by such a node), in order to decide whether to set up the dual-connectivity service for the UE and/or to decide which of multiple second nodes to use for the UE's dual-connectivity service. For instance, if a candidate second node has a threshold high uplink power headroom level, then, based on that fact, the first node may decide to not use that second node for dual-connectivity service of the UE. Or the first node may decide to use a given candidate second node based on the given candidate second node having a higher uplink power headroom level than one or more other candidate second nodes.

    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: 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.

    摘要: A base station that is configured to provide first-RAT service on multiple carriers will reserve at least one of the carriers for use in providing UEs with dual-connectivity service on the first RAT and a second RAT, and the base station will reserve at least one other of the carriers for use in providing UEs with standalone first-RAT service. For instance, a 4G base station that is configured to provide 4G service on multiple 4G carriers could reserve at least one of those 4G carriers for use in providing UEs with EN-DC service (where each UE would be served concurrently on a 5G carrier as well) and could reserve another one of those 4G carriers for use in providing UEs with standalone 4G service.

    摘要: A method and system for controlling service of user equipment devices (UEs) by a base station in a wireless communication system. In an example arrangement, the base station detects that uplink noise on its air interface is threshold high and that multiple UEs being served by the base station are threshold distant from the base station. In response to detecting this combination of factors, the base selects at least one of the threshold distant UEs for the base station to stop serving, with the selection being based on the UE having highest uplink transmission power among the multiple served UEs that are threshold distant from the base station, and the base station then causes handover of the selected UE from the base station.

    摘要: A method and system for controlling application of MU-MIMO. The disclosure provides for considering a device's power headroom as a basis to decide whether to provide the device with MU-MIMO service. For instance, a base station could determine which of the base station's served devices each have threshold low power headroom. And on at least that basis, the base station could select each such device to receive MU-MIMO service. Or faced with a choice between devices to receive MU-MIMO service, the base station could compare the devices' levels of power headroom and could select the devices that have lower power headroom to receive MU-MIMO service.

    摘要: A radio access network (RAN) determines whether transmission time interval (TTI) bundling is warranted for a wireless communication device (WCD) based on information contained in one or more reports from the WCD. The information may include a reference-signal value, such as a reference signal received power (RSRP) or a reference signal received quality (RSRQ), in a measurement report, an amount of data indicated in a buffer status report as being buffered by the WCD for transmission via one or more bearers in a bearer group, and a service class associated with the bearer group. If the RAN determines that TTI bundling is warranted for the WCD, the RAN may further select a TTI bundle size for the WCD. The RAN may select the TTI bundle size from among a plurality of values, which values may include a standard TTI bundle size and a smaller TTI bundle size.
