Abstract: This application relates to a communication method and apparatus. A network device receives first information from a terminal device, where the first information indicates a transmission capability of the terminal device. The network device determines, based on the first information, scheduling information supported by the terminal device, where the scheduling information includes a maximum quantity of data blocks and/or a maximum quantity of bits that can be transmitted in a single time domain unit. The network device schedules the terminal device based on the scheduling information. The network device can learn of an actual transmission capability of the terminal device, and therefore can determine a scheduling policy based on the actual transmission capability of the terminal device.

Abstract: A method describes that a lost first block in a first stripe is directly reconstructed based on a first result obtained from a target quantity of storage devices, so that there is no need to read an unlost block in the first stripe. The first block may be reconstructed provided that the target quantity of first results are obtained. An amount of data of the first result is less than that of the unlost block in the first stripe. Therefore, a data transmission process occupies less network bandwidth, and this improves block reconstruction performance.

Abstract: In a voltage conversion circuit, a sampling signal and a triangular wave signal are synthesized into a first signal, and the first signal and a second signal are compared to output a pulse-width modulation (PWM) signal. A frequency of the PWM signal may be determined by a frequency of the triangular wave signal. Therefore, the frequency of the PWM signal is fixed using the frequency-fixed triangular wave signal. Turning on or switching off of a power transistor in a voltage conversion subcircuit is controlled according to the PWM signal to convert a received direct current input voltage into a direct current output voltage, thereby implementing a fixed operating frequency for the voltage conversion circuit.

Abstract: In a data storage method, a storage system comprises first and second medium layers for data storage, wherein the performance of the first medium layer is different from the performance of the second medium layer. Based on the performance difference between the two layers, the storage system stores data in the first medium layer and the second medium layer based on different erasure code ratios. The different erasure code ratios correspond to different write amplification, and result in different storage space utilization.
