Title: Control method and circuit for earphone, and smart wrist-worn device
Inventor: SUI TAO
IPC: H04R1/10
Filed: 2019-09-25
Abstract: Disclosed is a control method for an earphone, which considers that misdetection may occur in the process of detecting that a wireless earphone is placed in a charging base, and at the same time, it is considered that the charging base will charge the wireless earphone after the wireless earphone is placed in the charging base. Therefore, on the basis of detecting that a wireless earphone is placed in a charging base, the present application uses the charging base charging the wireless earphone as a sign that the wireless earphone is successfully placed in the charging base. On the basis of the foregoing, in the present application, when detected that the wireless earphone is placed in the charging base, the wireless earphone is not immediately controlled to shut down, instead the wireless earphone is first maintained in a turned-on state, and only when detected that the charging base is charging the wireless earphone will the wireless earphone be controlled to shut down, thereby avoiding the false triggering of wireless earphone shutdown. Further disclosed are a control circuit for an earphone and a smart wrist-worn device, which have the same beneficial effects as those of the described control method.

Title: Secondary positioning reference signals for non-terrestrial networks in 5g new radio
Inventor: MA JUN
IPC: H04W4/02
Filed: 2020-02-07
Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.
