Abstract: A wireless communication network delivers multi-frequency service to User Equipment (UE). A primary node receives signaling from the UE that indicates secondary nodes along with their frequencies and signal strengths. The primary node selects candidate nodes based on the signal strengths for the secondary nodes. The primary node determines potential intermodulation interference between the primary frequency and the frequencies for the candidate set. The primary node selects a qualifying set from the candidate set based on the potential intermodulation interference. The primary node determines communication performance for the qualifying set and selects a serving set from the qualifying set based on the communication performance. The primary node wirelessly transfers signaling to the UE identifying the serving set and transfers signaling to the serving set identifying the UE. The serving set of secondary access nodes wirelessly transfer user data to the UE over their frequencies responsive to the signaling.

Abstract: Baseband circuitry receives and processes measurement reports from multiple User Equipment (UEs) at multiple locations and responsively determines radio metric variances at the multiple locations. The baseband circuitry receives attachment signaling from a new UE, determines the location for the new UE, and determines a measurement time period for the new UE based on the radio metric variance at the location of the new UE. The baseband circuitry transfers the measurement time period to the new UE. The baseband circuitry receives and processes a measurement report from the new UE and determines to add a secondary access node based on a radio metric for the secondary access node in the new measurement report. The baseband circuitry transfers network signaling to the secondary access node to serve the new UE and transfers additional user signaling to new UE to attach to the secondary access node.

Abstract: Embodiments herein disclose systems, methods, and computer-readable media for automatically adjusting settings of antenna elements to reduce radio link failures. In embodiments, a base station monitors radio link failures occurring at the base station that are associated with a first technology, such as 5G protocol. When the radio link failures meet or exceed a predefined or predetermined threshold, the base station may adjust a portion of antenna elements in an antenna array controlled by the base station, in some embodiments. For example, the base station may only adjust those antenna elements in the antenna array that are associated with the first technology, while other antenna elements in the same antenna array that are associated with a second technology, such as 4G protocol, are not adjusted.

Abstract: One or more elements of a communication system receives a first indicator that a first wireless device is within a first coverage area of a first access node and is also within a second coverage area of a second access node. The first access node and the second access node are both configured to provide a multi-user multiple-input multiple-output (MU-MIMO) operating mode. The communication system determines a first number of wireless devices attached to the first access node that are utilizing the MU-MIMO operating mode. The communication system identifies the first wireless devices as being configured as a relay node. The communication system, based on the first number meeting a first threshold, instructs the first wireless device to attach to the second access node.

Abstract: A mechanism for controlling operation of a first access node that supports operation according to a first radio access technology (RAT) but does not support dual-connectivity operation according to the first RAT and a second RAT. A system detects a high extent of occurrences of dual-connectivity-capable user equipment devices (UEs) being connected with the first access node when the dual-connectivity-capable UEs could instead connect with a second access node that supports the dual-connectivity operation. And in response, the first access node blocks dual-connectivity-capable UEs from being connected with the first access node while allowing UEs that are not dual-connectivity capable to be connected with the first access node.

The system includes a network load monitoring processor that measures a network load on carriers using a first RAT to produce a measured value and a buffer management processor that receives the measured value, performs a comparison of the measured value with a predetermined value, and dynamically modifies a size of the buffer when the measured value exceeds the predetermined value.

Abstract: A method and system for controlling air-interface resources on a radio-frequency (RF) carrier on which an access node provides wireless communication service. While the access node is set to apply at least two resource-reservations (e.g., PRB-reservations) that are mutually exclusive on the carrier, a computing system detects that resource-availability on the carrier is threshold low. And in response to the detecting, the computing system causes the access node to combine together the at least two resource-reservations on the carrier The combining together of the at least two resource-reservations on the carrier retains the at least two resource-reservations on the carrier but results in a reduction in aggregate total quantity of air-interface resources consumed by the at least two resource-reservations on the carrier.

Abstract: Methods are provided for dynamically modifying an SSB beam configuration. SINR and/or other network efficiency parameters are monitored at a cell site. It is determined that the SINR or other network efficiency parameter is lower than a threshold value. The current SSB beam configuration of the cell site is compared with other potential SSB beam configurations. Based on the comparing, an SSB beam configuration is compared with an optimal side lobe antenna gain and back lobe antenna gain to avoid interference with adjacent cell sites. In response to the identifying, the SSB beam configuration at the cell site is dynamically modified.

It is determined that a quantity of user devices using a first radio access technology at a base station is above a threshold. A current frequency allocation is then determined between the first radio access technology and a second radio access technology. Based on the quantity of user devices using the first radio access technology being above the threshold and the current frequency allocation, one or more user devices from the quantity of user devices are reallocated from the first radio access technology to the second radio access technology.

Abstract: Methods and systems are provided for dynamically modifying bandwidth allocation corresponding to a first radio access technology and a second radio access technology. A current allocation of channel bandwidth corresponding to the first radio access technology and the second radio access technology is determined. One or more radio frequency conditions associated with a base station may be monitored, which could include loading at a particular cell site or sector and/or user devices that have a guaranteed bit rate. Based on monitoring of the radio frequency conditions, the current allocation of the channel bandwidth corresponding to the first radio access technology and the second radio access technology is dynamically modified to a different allocation of channel bandwidth corresponding to the first radio access technology and the second radio access technology.

Abstract: A method and system for controlling application of MU-MIMO. The disclosure provides for considering a device's power class 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 that are threshold distant from the base station are each a high power device rather than a lower power device. 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' power classes and could select the devices that have higher power class to receive MU-MIMO service.

Abstract: A method and system for controlling connectivity of a user equipment device (UE), the UE being dual-connectivity capable. The UE detects that the UE has ping-ponged at a threshold high rate between standalone connectivity and dual connectivity. And responsive to at least detecting that the UE has ping-ponged at the threshold high rate between standalone connectivity and dual connectivity, the UE transmits, to an access node serving the UE, a report including an indication that the UE is not dual-connectivity capable, even though the UE is dual-connectivity capable. The access node could then use the indication in the report as a basis to forgo configuring of dual connectivity for the UE, which could thereby help discontinue the ping-ponging.

Abstract: A method and system for controlling wireless transmission to a user equipment device (UE) while the UE is served on a plurality of carriers each having a respective downlink bandwidth. An example method includes determining that a first carrier of the plurality of carriers has a wider downlink bandwidth than a second carrier of the plurality of carriers. And the method then includes, based at least on the determining, causing transmission to the UE on the first carrier to use a greater quantity of multiple-input-multiple-output (MIMO) layers than transmission to the UE on the second carrier.

Abstract: In a wireless access node, Packet Data Convergence Protocol (PDCP) circuitry identifies a noise metric for the wireless access node. The PDCP circuitry receives Downlink (DL) user data for User Equipment (UE). The PDCP circuitry allocates a first portion of the DL data and a second portion of the DL data based on the noise metric. The PDCP circuitry transfers the first portion of the DL data over first Radio Link Control (RLC) circuitry to first MAC circuitry. The PDCP circuitry transfers the second portion of the DL data over second RLC circuitry to second MAC circuitry. The first MAC circuitry schedules wireless delivery of the first portion of the DL data and transfers the first portion of the DL data to the UE over first Physical Layer (PHY) circuitry. The second MAC circuitry schedules wireless delivery of the second portion of the DL data and transfers the second portion of the DL data to the UE over second PHY circuitry.

Abstract: A mechanism to help control connectivity of a user equipment device (UE). When the UE is served by a master node (MN) that does not support VOP service, the MN will cause the UE to not have a secondary connection with a secondary node (SN) that would engage in control-plane signaling with the UE via the UE's master connection with the MN. For instance, in that situation, the MN could avoid setting up the secondary connection for the UE in the first place. Or if the secondary connection exists already, the MN could tear down that secondary connection. By causing the secondary connection to not exist, the mechanism may help to avoid problems with operation of the secondary connection as a result of the UE tuning away to facilitate voice service.

Abstract: Disclosed is a mechanism to help control which of multiple carriers a base station will serve a UE on—perhaps which carrier should be the UE's primary component carrier for carrier-aggregation service. The disclosed mechanism can apply in a scenario where a base station is configured to provide service on multiple carriers including at least a first carrier and a second carrier, and when the base station is serving one or more relays respectively on each carrier. In that scenario, the selection of a carrier on which the base station should serve a UE could be made based at least on a consideration of how many UEs are served in total by the one or more relays that the base station serves respectively on each carrier, such as by selecting the carrier having the fewest such relay-served UEs.
