Abstract: A method and system for generating performance measurements related to DL and UL packet delays through a NG-RAN are described. The NG-RAN receives GTP PDU monitoring packets from a UPF and, in response measures the DL delays of the packets to and UL delays from a UE. The NG-RAN determines the per 5QI and per S-NSSAI distribution of the DL and UL delays and sends the performance measurements to a service provider. The average DL and UL delays may also be provided to the service provider. The service provider is in the NG-RAN or a separate management system. For a network slice, service providers for different NG-RANs send the performance measurements to a network slice service provider, where the individual NG-RAN performance measurements are combined to provide both the average and distribution of the DL and UL delays in the network slice.

Abstract: A Bluetooth-based data transmission method is provided. The method is applied on a first device and includes the following steps: establishing a communication connection with a second device; determining a sniff interval which comprises a sniff wake-up window; entering a sniff mode; and transmitting a first data packet to the second device in the sniff interval. The transmission duration of the first data packet is longer than or equal to two time slots. The step of transmitting the first data packet to the second device in the sniff interval includes the steps of starting to transmit the first data packet to the second device in an even time slot of the sniff interval or in an odd time slot of the sniff interval. With the data transmission method of the present application, synchronization between transmission of the first device and reception of the second device can be realized.

Abstract: The present disclosure provides radio-frequency (RF) systems that can detect the presence of RF signals received by the system, as well as determine characteristics such as the operating frequency of RF signals, the type of RF source that transmitted each RF signal, and/or the location of each RF source with high precision and sensitivity while using low cost, scalable electronics that are versatile enough for deployment in a variety of environments. Such systems can employ a network of RF sensors that can coordinate in response to communication with a computer to perform any such detection and/or determination using trained models executed onboard the RF sensors and/or the computer. RF signals may have unique characteristics when received at one or more RF sensors that may be detected using trained models described herein, even in high noise or non-line of sight (LOS) environments and with low cost, low resolution RF receiver hardware.

Abstract: A limited-function, low-power wakeup receiver is based on frequency shift keying (FSK), avoiding the inherent problems of AM demodulation such as non-linearity of the amplitude detector. The FSK detector is easily realized in the digital domain. Due to the time discrete nature of FSK signals, the detector has a periodic response in frequency, allowing the signal to be demodulated at different offsets from the center frequency. The relaxed accuracy demands on the local oscillator frequency avoid the need for a power-hungry phase locked loop (PLL) circuit. To avoid potential loss if a signal coincides with one of the regular sensitivity nulls, the network at least occasionally transmits an FSK wakeup signal at a slightly shifted frequency, so at least one of the FSK wakeup signals will be received. Transmitting multiple frequency-shifted signals improves the likelihood of reception.

Abstract: This disclosure relates to methods, non-transitory computer readable media, and client devices that automatically initiate a wireless network connection (e.g., a pairing) with an auxiliary computing device based on recurring detection of a wireless broadcast signal from the auxiliary computing device.
