Abstract: A wireless network serves User Equipment (UEs) over Fifth Generation New Radio (5GNR) and Long Term Evolution (LTE). 5GNR circuitry allocates downlink data into a 5GNR portion and an LTE portion. The 5GNR circuitry transfers the 5GNR data portion to the UEs and transfers the LTE data portion to LTE circuitry. The LTE circuitry wirelessly transfers the LTE data portion to the UEs. The 5GNR and/or LTE circuitry measure UL noise and modify the 5GNR portion and the LTE portion based on the UL noise. The 5GNR circuitry allocates additional downlink data into a modified 5GNR portion and a modified LTE portion. The 5GNR circuitry wirelessly transfers the modified 5GNR data portion to the UEs. The 5GNR circuitry transfers the modified LTE data portion to the LTE circuitry. The LTE circuitry wirelessly transfers the modified LTE data portion to the UEs.

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.

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.

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.

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.

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.

Abstract: A method for configuring a base station to group UEs for MU-MIMO service, where the base station provides wireless communication service in a cell having a geometric size. In an example implementation, the method includes determining, based on the geometric size of the cell, a maximum quantity of UEs that the base station should allow per MU-MIMO group, and configuring the base station to apply the determined maximum quantity when grouping UEs for MU-MIMO service. For instance, the maximum quantity of UEs per MU-MIMO group could be set based on the radius of the cell.

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.

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.

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.

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.

A second subset of wireless devices in the sector that are not configured as relay nodes are also identified. One or more wireless device in the first subset of wireless devices are instructed, allocated resources, or otherwise controlled to not utilize the MU-MIMO operating mode.

Abstract: Systems and methods are provided for dynamically modifying the radio state of a user device based on monitored properties of the user device. One or more device properties associated with the power of the user device are monitored to determine a radio state change for the user device based on a triggering event. The triggering event corresponds to the one or more monitored device properties, and based on the determined radio state change for the user device, the radio state of the user device is automatically modified. Based on the modified radio state, information is transmitted to a cell site, the information including modified user device capability information. Based on the modified user device capability information, the user device receives communications from the cell site.

A number of latency sensitive wireless devices attached to the relay nodes can be determined. A latency sensitive wireless device can be a wireless device running a latency sensitive application. A latency sensitive relay node can be a relay node attached to the donor access node having an attached latency sensitive wireless device. A maximum number of relay nodes attached to the donor access node can be set, for example, based on the number of latency sensitive wireless devices attached to latency sensitive relay nodes.

Abstract: When a first node is considering setup of dual-connectivity service for a UE, the first node will take into consideration data-buffer occupancy of one or more candidate second nodes, 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 threshold high data-buffer occupancy, 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 lower data-buffer occupancy than one or more other candidate second nodes. Further, data-buffer occupancy could be based on downlink data buffering and/or uplink data buffering.

Abstract: When a first node is considering setup of dual-connectivity service for a UE, the first node will take into consideration uplink noise at one or more candidate second nodes, 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 threshold high uplink noise, 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 lower uplink noise than one or more other candidate second nodes.

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.

Abstract: In a wireless access point, a Long Term Evolution (LTE) Common Unit (CU) exchanges media-conferencing data with an LTE Distributed Unit (DU). The LTE DU exchanges the media-conferencing data User Equipment (UEs). The LTE CU determines a media-conferencing load. Based the media-conferencing load, the LTE CU determines a Fifth Generation New Radio (5GNR) Uplink (UL) allocation and an LTE UL allocation for an internet-access service. The LTE CU transfers LTE signaling and 5GNR signaling for delivery to the UEs. The LTE DU receives LTE UL internet data from the UEs per the LTE UL allocation and transfers the LTE UL internet data to the LTE CU. The 5GNR DU receives 5GNR UL internet data from the UEs per the 5GNR UL allocation and transfers the 5GNR UL internet data to the 5GNR CU. The LTE CU may also implement 5GNR/LTE downlink allocations for the internet-access service based on the media-conference load.

The system comprises an access point that is configured to transmit wireless downlink signals to a WCD using a first communication protocol and a second communication protocol. A processor collects at least one set of data, which may include historical and current data such as noise interference and GPS location. Then, the processor analyzes the at least one set of data, and determines an updated transmission power for each of the first communication protocol and the second communication protocol. Subsequently, the system proactively instructs the WCD to communicate to the access point the updated transmission power for each communication protocol.

Abstract: A method and system for controlling application of MU-MIMO. The disclosure provides for considering a device's rate of change of RF conditions 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 rate of change of RF conditions. 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' rates of change of RF conditions and could select the devices that have lower rate of change of RF conditions to receive MU-MIMO service.
