Abstract: Determining when to display a Fifth Generation (5G) service indicator is described herein. In an example, a user equipment (UE) can compare capabilities supported by the UE with capabilities available to the UE (e.g., in a geographic area of the UE) to determine whether the UE can display the 5G service indicator. In some examples, such capabilities can be determined based at least in part on E-UTRAN New Radio-Dual Connectivity (EN-DC) combinations of frequency bands.

Abstract: A user equipment (UE), such as a mobile phone, may support multiple power classes. Power classes can define maximum output power levels for uplink transmissions. A base station of a radio access network (RAN) can, based on metrics reported by the UE, dynamically instruct the UE to switch to using a different power class. For example, the base station may instruct the UE to switch from using a first power class with a higher maximum output power to using a second power class with a lower maximum output power, in order to preserve battery life of the UE in situations in which the second power class provides sufficient output power for uplink transmissions to reach the base station.

Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to dynamically switch the primary cell (PCell) used by user equipment (UE) for carrier aggregation (CA) in 5G cellular networks. Instead of remaining anchored to an initially selected PCell, a different PCell may be dynamically selected based on different network conditions. The network conditions may include network congestion, network capacity, uplink speed, location of the UE, an activity of the UE (e.g., is the UE uploading or planning to upload data), and the like. As an example, the PCell may be selected from an n41 (2.5 GHz) cell and an n71 (600 MHz) cell. When the UE is close to the n41 cell, the n41 cell may be selected. When the UE is moving away from the cell center and toward the cell edge, the PCell may be switched from the n41 cell to the n71 cell.

Abstract: A telecommunication network associated with a wireless telecommunication provider can be configured to switch between New Radio (NR) Dual Connectivity (DC) and NR Carrier Aggregation (CA) in 5G cellular networks. According to examples, a UE is not limited to using a single mode (e.g., either NR CA or NR DC) that is initially selected for use by the UE. For example, a UE can be reconfigured during a session to switch from NR DC to NR CA when the UE moves toward mid-cell and/or a cell edge. In other examples, the UE can be reconfigured to switch from NR CA to NR DC when the UE moves closer to the cell. To determine when to switch, one or more network conditions (e.g., UE RF conditions) can be monitored. In some examples, a gNB can monitor power headroom reports (PHRs) received from the UE to determine when to switch.

Abstract: Techniques for measuring and reducing signal misalignment in a dual connectivity environment are discussed herein. When using Non-Standalone Architecture (NSA), a device initially communicates with a network using a Long-Term Evolution (LTE) connection. After the LTE connection is established, an LTE base station may instruct the device to measure signal strength of a neighboring New Radio (NR) cell during a specified LTE measurement gap. When the NR cell is implemented by an indoor NR base station, the NR signal may not be sufficiently synchronized with the LTE signal and the device may be unable to measure the NR signal during the measurement gap. In these cases, the device can determine the frame timing difference between the LTE and NR signals, obtain an adjusted measurement gap that reduces any measurement gap misalignment, and attempt to measure the signal strength of the NR cell using the adjusted measurement gap.

Abstract: Techniques for dynamically adjusting Connected Mode Discontinuous Reception (CDRX) parameters are discussed herein. For example, a base station may receive information associated with downlink data to be sent to a user equipment (UE) and/or information associated with the UE itself. The base station may adjust CDRX parameters to be implemented on the UE based on the received information in order to maximize performance of the UE. In some examples, the base station may adjust CDRX parameters based on a traffic type (e.g., voice traffic, video traffic, data traffic, etc.) associated with the downlink data, UE state parameters associated with the UE, and/or Received Signal Strength Indicator (RSSI) data associated with the UE.

Abstract: Systems, devices, and techniques described herein relate to intelligently allocating network resources to Quality of Service (QoS)-sensitive data traffic. An example method includes identifying a request to deliver QoS-sensitive services to a User Equipment (UE) over at least one delivery network. The at least one delivery network may include at least one reserved resource and at least one pooled resource. The QoS-sensitive services are determined to be delivered over the at least one pooled resource. In addition, delivery of the QoS-sensitive services is caused over the at least one pooled resource.

Abstract: A user equipment (UE) may support establishing an E-UTRAN New Radio-Dual Connectivity (EN-DC) connection with a telecommunication network that involves both a Long-Term Evolution (LTE) connection and a fifth generation (5G) connection. However, the EN-DC connection may drain a battery of the UE more quickly than the LTE connection would alone. Accordingly, an EN-DC switcher executing on the UE can determine when the UE should use the LTE connection alone or use the EN-DC connection, for example based on factors that may indicate when a user of the UE is less likely to perceive improved throughput or other benefits of the EN-DC connection.

Abstract: An orchestration and mediation (O/M) stack to be installed in a user device that subscribes to a carrier system is provided. The O/M stack configures the user device to receive a policy for accessing a plurality of different network slices that are logical networks virtualized on a physical infrastructure of the carrier system. The O/M stack configures the user device to coordinate each application's access to different services provided by the plurality of different network slices. An application is allowed access to a particular network slice when the application and the user device meet a condition specified by the received policy for accessing the particular network slice.

Abstract: A user equipment (UE) may perform multiple searches within a specified search period to locate the wireless band that provides the most throughput. For instance, if the UE finds a low band with time remaining in the search period, the UE continues to search for a higher frequency wireless. In some examples, the UE attempts to locate a high band within a next portion of the search period. If the UE finds the high band, then the UE will use that band since it provides the most throughput of the available bands. If the UE does not find the high band, then the UE searches for a mid-band for another portion of the search time. By prioritizing higher bands over the first available band that is located in the initial search, the UE will connect to the band that provides the best user experience and the most throughput.

Abstract: A component of a cellular communication system is configured to prioritize data packets based on packet tags that have been associated with the data packets. The packet tags may comprise an application identifier and a customer identifier, as examples. A Packet Data Convergence Protocol (PDCP) layer of a radio protocol stack receives a data packet and associated packet tags and assigns the data packet to a preferred transmission queue or a non-preferred transmission queue, based on the packet tags associated with the data packet. In order to manage queue overflows, data packets of the non-preferred transmission queue may be discarded when they have been queued for more than a predetermined length of time. Data packets of the preferred transmission queue, however, are retained regardless of how long they have been queued.

Abstract: A knowledge base of cell information can be built and made available to one or more mobile devices. A mobile device with access to this cell information may proactively perform a radio signal scan at a frequency of an expected cell(s) that is/are indicated in the cell information (e.g., if the expected cell is associated with a serving cell and/or with a geolocation that corresponds to the current Global Positioning System (GPS) location of the mobile device). After performing the radio signal scan, the mobile device may store measurement information (e.g., signal strength) about the expected cell(s) in local memory of the mobile device, and, upon receiving an instruction from the serving cell, the mobile device may access the stored measurement information from its local memory, and may send the measurement information to the requesting serving cell.

Abstract: Providing access to Fifth Generation (5G) wireless communication services via an Application Programming Interface (API) is described. In an example, a request for 5G wireless communication services associated with a 5G wireless communication service provider can be received via the API. The 5G wireless communication service provider can determine that it can accommodate the request and can cause a notification to be presented via the application, wherein the notification includes an indication that the 5G wireless communication services are available. Based at least in part on receiving an indication of an input associated with the notification, the 5G wireless communication services can provide 5G wireless communication services to a user device via the API.

Abstract: Techniques for network-based and sender-based data packet prioritization for downlink transmissions are discussed herein. Packets can be tagged or associated with information indicative of a priority of the packet for downlink transmission to a user equipment (UE). A priority level can be determined based on an application identifier or type associated with a data request, a level of user interaction with the UE, network conditions, and other factors. Packets can be received by a PDCP layer of a base station for sending based on the priority. Packets may be associated with a primary priority level associated with a QCI level and a secondary priority level based on UE and/or network factors discussed herein. Packets associated with a same QCI may be prioritized to optimize transmission of downlink data associated with a single UE or between transmission of downlink data associated with a plurality of UEs.

Abstract: Described herein are techniques, devices, and systems for providing an optimal voice experience over varying radio frequency (RF) conditions while using EVS audio codecs. A user equipment (UE) may adaptively transition between using a music-capable EVS codec (e.g., EVS-FB) as a default audio codec that provides a first audio bandwidth and a different EVS audio codec that provides a second audio bandwidth that is less than the first audio bandwidth. The transition to the different EVS audio codec may occur in response to determining a value indicative of a RF condition associated with a serving base station is less than a threshold value, which allows for providing preserving at least a minimal level of voice quality in degraded RF conditions.

Abstract: The disclosed technology provides a system and method for scheduling downlink transmissions and for granting uplink frequency resources to a user device such that concurrent transmissions and receptions by the user device, or multiple concurrent transmissions and receptions by the user device, does not lead to deleterious intermodulation distortion or at least minimizes the extent of any such resulting intermodulation distortion.
