  • Patent number: 11026282
    Abstract: A mechanism for controlling configuration of dual connectivity for a UE that has a first connection with a first access node. The first access node could make a determination whether a beamwidth of a second access node with which the UE does not yet have a connection is at least as wide as a predefined threshold angle. If not, then the first access node could apply blind addition, in which the first access node works to add for the UE the second connection without requiring as a condition precedent the UE reporting being in threshold strong coverage of the second access node. Whereas, if so, then the first access node could instead apply threshold-based addition, in which the first access node works to add for the UE the second connection if and when the UE reports being in threshold strong coverage of the second access node.

  • Patent number: 11012142
    Abstract: A wireless network may have two types of wireless services such as 4G and 5G. The 4G service may not be configured to communicate with wireless devices using multi-user multiple-input multiple-output (MU-MIMO) operating mode, while the 5G service can communicate using MU-MIMO. When a relay node is positioned such that it is within the coverage areas of both types of wireless service, the relay node is instructed to attach to the wireless service that is not capable of utilizing the MU-MIMO operating mode. Conversely, wireless devices within the coverage areas of both types of wireless service that are not configured as relay nodes may be instructed to attach to the wireless service capable of utilizing the MU-MIMO operating mode so that these wireless devices may receive the benefit of utilizing MU-MIMO.

  • Patent number: 11012863
    Abstract: 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.

  • Patent number: 11006470
    Abstract: A method and system for controlling carrier use to help manage uplink noise. A base station detects threshold high uplink noise on a carrier, and the base station responsively configures itself to prevent the carrier from being added as a secondary carrier for carrier-aggregation service, though the base station still allows establishment of new radio-link-layer connectivity encompassing the carrier as a primary serving carrier.

  • Patent number: 10999883
    Abstract: 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.

  • Patent number: 10951385
    Abstract: When a wireless communication system serves a UE over a connection according to a first radio access technology (RAT) and the connection encompasses a carrier in a first band (first-band carrier), the system decides of whether to configure for the UE's connection intra-band carrier aggregation by adding to the connection another first-band carrier or rather to configure for the UE's connection inter-band carrier aggregation by adding to the connection a second-band carrier, with the decision being based on a determination of whether (i) the other first-band carrier is usable in providing service under a second RAT different than the first RAT and (ii) the candidate second-band carrier is not usable in providing service under the second RAT. The system then configures carrier-aggregation in accordance with the decision.

  • Patent number: 10952017
    Abstract: A wireless access point selects a Multiple User Multiple Input Multiple Output (MU-MIMO) geofence for a wireless user device based on its device location. The wireless access point transfers MU-MIMO signals to the wireless user device based on the selected MU-MIMO geofence. The wireless access point determines MU-MIMO information for the device location like MU-MIMO gain, user device type, or some other metric. A MIMO control system processes the MU-MIMO information for the device location and responsively modifies the MU-MIMO geofence. The wireless access point selects the modified MU-MIMO geofence for another wireless user device based on its device location. The wireless access point transfers other MU-MIMO signals to the other wireless user device based on the modified MU-MIMO geofence.

  • Patent number: 10932163
    Abstract: A method for controlling handover of a user equipment device (UE) between a first access node and a second access node. The first access node could select a handover process with the selecting being based on whether (i) the source access node and target access nodes are both dual-connectivity capable or both not dual-connectivity capable or rather (ii) one of the access nodes is dual-connectivity capable and the other of the access nodes is not dual-connectivity capable. For example, if both are dual-connectivity capable or not dual-connectivity capable, then the source access node could opt for X2 handover. Whereas if one is dual-connectivity capable and the other is not dual-connectivity capable, then the source access node could opt for S1 handover.

  • Patent number: 10917125
    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.

  • Patent number: 10856166
    Abstract: A wireless relay serves wireless User Equipment (UEs). In the wireless relay, a user transceiver exchanges user signaling and user data with the UEs and exchanges access signaling and the user data with a network transceiver. The network transceiver determines wideband radio measurements and wirelessly exchanges the user data and relay signaling with a wireless data network over the wideband. The relay signaling includes the access signaling and the wideband radio measurements. The network transceiver determines when communication quality for the UEs falls below a quality threshold. In response, the network transceiver determines sub-band radio measurements for the sub-bands within the wideband and wirelessly exchanges additional relay signaling with the wireless data network over the sub-bands. The additional relay signaling has the sub-band radio measurements. The network transceiver may receive instructions to determine sub-band radio measurements instead of wideband radio measurements.
