Abstract: This disclosure provides methods and apparatuses for multi-carrier operation in wireless communication networks. In various examples, a user equipment (UE) obtains a first radio resource control (RRC) configuration associated with a first carrier, the first carrier being associated with a first cell, a first bandwidth part (BWP) configured for the first cell, or at least one RRC profile respectively including a set of RRC parameters. The UE generates, at least in part from the first RRC configuration, a second RRC configuration associated with a second carrier, the second carrier being associated with a second cell, a second BWP configured for the second cell, or the at least one RRC profile. The UE communicates, with a network entity, over the first carrier and the second carrier. The methods and apparatuses provide lower memory requirements, reduced signaling overhead, and reduced secondary cell (SCell) activation time.

Abstract: In a method for controlling a virtual object, at least one virtual vehicle and a vehicle entry control element are output for display in a virtual scene. A first virtual vehicle of the at least one virtual vehicle that is associated with the vehicle entry control element is obtained. A first indication of which of the at least one virtual vehicle is the first virtual vehicle that is associated with the vehicle entry control element is output for display. A trigger operation performed on the vehicle entry control element is received. Based on the trigger operation performed on the vehicle entry control element when the vehicle entry control element is associated with the first virtual vehicle, the virtual object is controlled to automatically enter the first virtual vehicle associated with the vehicle entry control element.

Abstract: A direct current charging apparatus, a powertrain, and an electric vehicle. The direct current charging apparatus which includes a direct current charging interface, a switch module, and a direct current voltage conversion module is configured to charge power battery of the electric vehicle. The direct current charging interface is configured to connect a positive electrode and a negative electrode of a power supply apparatus and a positive electrode and a negative electrode of the power battery to form a charging loop. The switch module is configured to connect or disconnect the charging loop. The direct current voltage conversion module is configured to output a preset direct current voltage to the positive electrode and the negative electrode of the power supply apparatus. When the charging loop between the power battery and a charging pile is connected again, charging can be resumed without re-swiping card/re-scanning QR code.

Abstract: A steel, a steel mechanical part, an electronic device, and a preparation method for a steel mechanical part are provided. The steel includes components of the following mass percentages: chromium: 7% to 11%, nickel: 2% to 7.5%, cobalt: 6% to 15%, molybdenum: 4% to 7%, oxygen: a trace to 0.4%, carbon: a trace to 0.35%, and iron: 50% to 80%. The steel provided in this application has relatively high mechanical strength and is not easily deformed, and therefore a risk of fracture caused when an electronic device using the steel falls off from a height is reduced.

Abstract: A frequency regulation method and apparatus is applied to an insulation impedance detection apparatus in a direct current power system, and relates to the field of security monitoring technologies of a direct current electrical system. The method includes: collecting sampling voltages at a sampling point for at least three time points; determining a voltage frequency regulation manner based on the sampling voltages, obtained through sampling, at the at least three time points; and then regulating a voltage frequency of a power supply according to the determined voltage frequency regulation manner. The voltage frequency of the power supply can be regulated based on the at least three sampling voltages obtained through sampling. Therefore, the insulation impedance detection apparatus reduces insulation impedance detection duration while ensuring accuracy of measured insulation impedance.

Abstract: A method and apparatus are disclosed for use with multiple input, multiple output (MIMO) signal processing techniques, which reduce the amount of memory and memory bandwidth used to store and access filter coefficients by compressing a filter coefficient based at least in part on one or more neighboring filter coefficients for storage and decompressing the filter coefficients when retrieved. The decompressed filter coefficients can be used with a MIMO filtering technique, and/or can be used to compress or decompress additional coefficients.

Abstract: A multi-channel communication transceiver configured to communicate over multiple channels, such as multiple twisted pair conductors, and implement MIMO processing is disclosed. The MIMO processing occurs in a separate MIMO co-processor, which may be a DSP type processor executing machine readable code or a dedicated MIMO filter. The MIMO co-processor may be located on a separate integrated circuit and interface with the transceiver via one or more data paths and one or more control data paths. Control data is exchanged to facilitate processing of the data in the MIMO filter. A slicer output or an error term, may be forwarded to the MIMO co-processor or generated within the co-processor.
