Abstract: Embodiments of this application disclose a data processing method, which can be applied to a clock synchronization network system. The system can correct, based on a clock frequency error or a time error, a data timestamp of a data packet collected by the system in a time period in which there is no reference clock, so that a corrected system time of the data packet is consistent with a reference time. This improves accuracy of data record.

Abstract: Disclosed are an information sending method, information receiving method, apparatus, and device. The information sending method includes: receiving a physical sidelink feedback channel (PSFCH); determining a first duration; and sending a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) not earlier than a first moment, where the first moment is a moment the first duration after an end moment of receiving the PSFCH. A terminal device does not send the PUCCH or the PUSCH before the moment the first duration after the end moment of receiving the PSFCH. Because the terminal device can determine the first duration, it is ensured that the terminal device may have sufficient time to process the PUCCH or the PUSCH. The PUCCH or the PUSCH may be used to carry sidelink hybrid automatic repeat request (HARQ) information, and the HARQ information may be generated based on the received PSFCH.
