Abstract: A system for appending an emergency call (e.g., E911) with a location is described herein. The system appends the emergency call to a public safety answering point (PSAP) with a location from which the E911 call occurred. A user equipment (UE), which places the emergency call, connects to the beacon via short-range communication and acquires the location from a beacon. The UE transmits the location to the PSAP via a telecommunications network.

Abstract: A cellular communication device is configured to use Non-Standalone Architecture (NSA) for communicating with a cellular communication network using 4th-Generation (4G) Long-Term Evolution (LTE) and 5th-Generation (5G) New Radio (NR) radio access technologies. In NSA mode, the device may receive separate transmit power control commands for LTE and NR transmissions, respectively. In some situations, the cellular communication device may be commanded to use LTE and NR transmit powers that when combined would exceed regulatory limits or performance limits. In these situations, LTE and NR uplink transmissions are scheduled to implement time-division multiplexing, so that the LTE and NR uplink transmissions occur during different time intervals rather than concurrently.

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.

Abstract: Systems and methods of testing the handling of, or response to, transmitted Wireless Emergency Alerts (WEA) that include a geofenced area. The testing can include providing first location Global Positioning System (GPS) signals to user equipment, causing the user equipment to determine it is geographically located at the first location. A WEA alert can be provided to the user equipment and the WEA can include a geofenced area that does not include the first location. The user equipment can be provided GPS signals corresponding to a second location that is within the geofenced area of the WEA. Verification can then be performed to check that the user equipment displays the WEA alert, or message, in response to the user equipment determining its geographical position as corresponding to the second location that is within the geofenced area.

Abstract: Systems and methods discussed herein are directed to selecting and attaching to different cells within wireless communication networks when multiple cells are available. An electronic device determines that a 5G new radio (NR) radio access topology and a non-standalone radio access topology are available within a wireless communication network. The electronic device obtains a bandwidth index for the NR radio access topology and a bandwidth index for the non-standalone radio access topology and compares the two bandwidth indices. Based at least in part on results of the comparison, the electronic device selects one of either (i) the NR radio access topology or (ii) the non-standalone radio access topology and attaches to the selected topology.

Abstract: Systems and methods of providing a location that include receiving location data from user equipment, such as a cellphone or mobile device, and providing the location data in an acceptable form to emergency services, such as a Public Safety Answering Point (PSAP). The location data from the user equipment can undergo a shape conversion process prior to being transmitted to emergency services. The systems and methods evaluate the received location data to determine if a semimajor and a semiminor axis of the received location data are equal in magnitude. If so, the shape conversion process is bypassed to prevent error from being introduced into the location data.

Abstract: A configurable radio frequency filter is discussed herein. A device can include a filter component that includes multiple filters coupled between a radio frequency integrated circuit (RFIC) and one or more antennas via individual switches. A filter of the filter component may comprise a bandpass filter configured to pass specific frequencies. Filters of the filter component can comprise pass bands that are mutually exclusive or at least partially overlapping. A device can receive a channel allocation in a Citizens Broadband Radio Service (CBRS) band from a Spectrum Access System when initiating a carrier aggregated communication. In response to receiving the channel allocation, the device can select one or more filters of the filter component for filtering signals to and from an antenna component.

The method includes receiving a battery exchange request from the work machine, calculating a synchronization location and a synchronization time of the work machine and the battery exchange device, generating pre-judgment information, sending the pre judgment information and a synchronization command to the battery exchange device to control the battery exchange device to move toward the work machine according to the pre-judgment information and the synchronization command, continually receiving the first status information from the work machine and second status information from the battery exchange device, determining whether synchronization of the work machine and the battery exchange device is complete, and sending a battery exchange command to the battery exchange device to control the battery exchange device to exchange the battery of the work machine.

Abstract: Techniques for improving signal quality of communication between a user equipment (UE) and a base station by launching a supplemental communication device as the UE experiences a degradation of the signal quality are discussed herein. In some cases, the techniques can be used to improve signal quality of a Fifth Generation (5G) millimeter wave band communication. Upon detecting that the signal quality has fallen below a preselected threshold, the supplemental communication device may be launched from a platform associated with the UE to establish an improved communication with the base station that is closer to a point-to-point communication while maintaining a communication with the UE. The supplemental communication device may track the movement of the UE and maintain the point-to-point communication with base station by directionally orienting its antenna(s) towards the base station and monitor and/or detect its surroundings to avoid physical obstructions.

Abstract: Systems and methods for managing multiple network connections for user equipment (UE) are disclosed. The systems and methods can monitor power headroom (PHR) reports on one or more networks. When the PHR report for a UE approaches a first predetermined level on a first network, the system can evaluate the UE for a predetermined amount of time. If during the predetermined amount of time, the PHR on the first network increases to a second predetermined level—i.e., to a level where the transmission power used by the UE is closer to a maximum transmission power that the UE can provide—the UE can be instructed to disconnect from the network. This can enable the UE to disconnect in a controlled manner rather than simply letting the connection “drop” due to radio link failure.

The PDU includes a detecting module and a storing module, the monitoring device includes an amplifying module and a processing module. The detecting module obtains signal as to voltage and current relating to a power supply, and the storing module stores data as to calibration. The amplifying module obtains the signal as to voltage and current, and amplifies the same. The processing module obtains the amplified signal and processes the amplified to obtain data as to electrical flow. The processing module can obtain calibration data from the storing module, and apply corrections according to the calibration data.

Abstract: A portable electronic apparatus and a battery power management method thereof are provided. The method includes the following steps. A discharge current of a battery is detected. Whether the discharge current is greater than a current threshold within a predetermined period is determined. If the discharge current is not greater than the current threshold within the predetermined period, whether a fully charge capacity of the battery is less than a battery capacity threshold is determined. If the fully charge capacity of the battery is not less than the battery capacity threshold, a relative state of charge of the battery is controlled to be maintained within a first power range. If the fully charge capacity of the battery is less than the battery capacity threshold, the relative state of charge of the battery is controlled to be maintained within a second power range.

Abstract: Techniques for time-division multiplexing for extending 5th Generation (5G) network coverage are described herein. In an example, a device operating in a dual transmission mode for transmitting data via a first network node associated with a 5G network and a second network node associated with a 4th Generation (4G) network at or near a same time, can determine a measurement associated with a transmission and/or receiving characteristic. The device can determine that the measurement meets or exceeds a threshold and, based at least in part on determining that the measurement meets or exceeds the threshold, the device can transition to an alternating transmission mode for transmitting data via the first network node and the second network node in an alternating pattern thereby extending 5G network coverage.

Abstract: This disclosure describes techniques for charging multiple heterogenous user equipment over-the-air at a mass scale. The techniques involve utilizing one or more dedicated radio frequency (RF) sources such as charging stations that include transmitters for transmitting RF energy to one or more user equipment including receiver components. The user equipment is configured to convert the RF energy into direct current (DC) power so as to allow the transmitters to provide power on demand for a number of close range wireless user equipment.

Abstract: A network base station can select, for each of one or more attached terminals, a respective downlink transmission mode (DTM) based at least in part on respective channel condition information (CCI). The base station can determine a subframe allocation of DTMs to subframes of a radio frame, and transmit downlink data to terminals based the subframe allocation. Additionally or alternatively, the base station can receive load information from a second base station associated with a different access network and determine the subframe allocation based on the load information. The subframe allocation can associate a specific access network with each subframe. Additionally or alternatively, the base station can send the subframe allocation to the second base station. Additionally or alternatively, the base station can determine a proportion of GBR traffic of a particular DTM, determine a reference-signal transmission rate associated with that DTM, and transmit reference signals accordingly.
