Abstract: This application provides a control information sending method and a communication apparatus. According to the method, a terminal may determine, based on first information, a resource occupied by transmission according to a first communication protocol; determine, based on the resource occupied by transmission according to the first communication protocol, that a first resource is an available resource; and transmit control information on the first resource according to a second communication protocol. This can avoid control information transmission according to the second communication protocol by using the resource occupied by transmission according to the first communication protocol, thereby helping avoid a resource conflict between transmission according to the first communication protocol and transmission according to the second communication protocol.

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: Embodiments of this application disclose a feedback indication method and a communications apparatus, and relate to the communications field, to unify behavior of a transmitting party and a receiving party. This ensures data transmission performance as far as possible. The method includes: A transmitting node determines a first message. A first field in the first message is set to be null, and the first field is used to indicate a time-frequency resource that carries hybrid automatic repeat request HARQ information. The transmitting node sends the first message to a receiving node. The first message is used to indicate the receiving node to delay feeding back HARQ information corresponding to a first transport block TB, or the first message is used to indicate the receiving node to give up feeding back the HARQ information corresponding to the first TB. The first TB is a transport block scheduled by the first message.

Abstract: Embodiments of the present disclosure include example device-to-device communication methods and terminal devices. One example method includes determining, by a terminal device, a first resource, where the first resource is some time-frequency resources in a first resource set, where the first resource set is all time-frequency resources that can be used to detect a first transmission resource. The first transmission resource is a spectrum resource used to transmit first data. The terminal device can then perform detection for the first transmission resource in the first resource. In some instances, the terminal device can then send first data on the first transmission resource.

Abstract: The invention relates to device-to-device (D2D) communications technologies, and in particular, to a method, apparatus, and device for control signaling processing. A method of receiving a control signaling is applied to a D2D communication process. The method receives, by a second device, a control signaling sent by a first device, where the control signaling carries attribute identification information of service data that the first device needs to send. The method determines, by the second device according to the attribute identification information, whether the service data is data required by the second device. The method receives, by the second device, the service data if the service data is the data required by the second device. The method, apparatus, and device for control signaling processing of the invention are applied to selectively receive or demodulate service data, and reduce reception complexity and power consumption of a receiver user equipment (UE).
