Abstract: The present disclosure relates to quality of service (QoS) information notification methods, devices, and systems. In one example method, a user plane network element obtains a first QoS notification, where the first QoS notification includes first QoS information used to indicate QoS of a target service. The user plane network element sends first indication information to an application network element to which a QoS notification needs to be reported, where the first indication information is used to indicate a second QoS notification, the second QoS notification includes second QoS information of the target service, and the first QoS notification is the same as the second QoS notification, or the second QoS notification is determined based on the first QoS notification.

Abstract: Example methods, devices, and apparatuses are discussed. An example method includes determining that a condition associated with triggering a registration procedure is satisfied. The condition comprises that a second tracking area (TA) supports a first slice. The second TA belongs to a current registration area (RA) of the terminal device. The first slice is rejected in the current RA, wherein the terminal device is in the second TA. The example method further includes,n response to the determination, sending a second registration request message to a core network device. The second registration request message requests to access the first slice. The second registration request message comprises information about the first slice.

Abstract: Continuous-time (CT) analog-to-digital converters (ADCs) implementing digital correction of digital-to-analog converter (DAC) errors are disclosed. In a CT pipeline stage of a CT ADC, a CT analog input signal is sent to two different paths. A first path (a “feedforward” path) includes a cascade of a sub-ADC and a sub-DAC. A second path (a “forward” path) includes an analog delay circuit to align the delays of the input signal in the feedforward and forward paths. A combiner subtracts the output of the analog delay of the forward path from the output of the sub-DAC in the feedforward path to generate a residue signal. Devices and methods disclosed herein are based on recognition that, if the errors introduced by the sub-DAC are known, they can be corrected in the digital domain during reconstruction, achieving superior NSD and distortion performance compared to conventional approaches.
