  • Publication number: 20220300064
    Abstract: This application discloses a voltage scaling method and an electronic device. The method is applied to an electronic device having a processor and a power supply that supplies power to the processor. The method includes the processor sending power supply scaling information to the power supply based on an operating frequency in a next time period. The method further includes the power supply determining, based on the power supply scaling information, a supply voltage Vout used to supply power to the processor. The supply voltage Vout decreases as a load current of the power supply increases. Vmin?Vout?V, where Vmin is a lowest supply voltage of the processor at the operating frequency in the next time period, and V is a specified supply voltage of the processor at the operating frequency in the next time period.

  • Publication number: 20220303730
    Abstract: This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.

  • Publication number: 20220301417
    Abstract: A bridge device, in communication with a smart device, functions to command one or more controllable appliances in response to communications received from the smart device. The bridge device also includes input elements by which the bridge device can be used to directly command common functional operations of the one or more controllable appliances. In this manner, common functional operations, such as volume control, playback pause/resume control, etc., may be made readily available without necessitating the use of the smart device, whilst the more sophisticated GUI provided by the smart device remote control app may be advantageously utilized when more complex or less frequently used command functions are to be performed.

  • Publication number: 20220303767
    Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network, generating an identifier corresponding to the first credential, and generates a multi-access edge computing (MEC) authorization parameter. The UE then transmits an application registration request message to a server associated with an edge data network, the application registration request message including an indication of the first credential, the identifier corresponding to the first credential and the first authorization parameter. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

  • Publication number: 20220304062
    Abstract: A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index, of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

  • Publication number: 20220303020
    Abstract: Embodiments of this application provide a central unit, a remote unit, a small cell system, and a communication method. A digital-to-analog conversion (DAC) module and an analog-to-digital conversion (ADC) module are disposed in the central unit, so that the central unit transmits an analog optical signal to the remote unit. When the central unit transmits the analog optical signal to a plurality of remote units, because a processing delay of an analog component in analog transmission is usually at a nanosecond level, and a total delay formed by a path transmission delay and the processing delay fluctuates slightly or even is fixed, synchronization of the plurality of remote units can be easily implemented in the central unit through calibration. Therefore, it is possible to easily implement a distributed MIMO function.

Measurements of target gNB CSI-RS samples associated with a target gNB may be performed, wherein the CSI-RS samples associated with the source gNB and the CSI-RS samples associated with the target gNB are transmitted in a burst structure. A subset of the source gNB CSI-RS samples and the target gNB CSI-RS samples may be filtered using a layer 1 or a layer 2 filter. A filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples may be generated. Based on the generated filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples, determining whether a handover from the source gNB to the target gNB is to occur.
