Abstract: Embodiments of the present invention provide a subframe indication method and a device. A first device determines subframe indication information that indicates at least one of uplink control signaling, downlink control signaling, and data of a first subframe, and sends the subframe indication information to a second device, so that the second device determines a type of the first subframe based on the subframe indication information. In this process, the first device needs to send, to the second device, only the subframe indication information that indicates at least one of parts of the first subframe, and the second device may determine the type of the first subframe based on the subframe indication information, so as to reduce overheads of the subframe indication information.

Abstract: A device-to-device (D2D) communication method and a D2D terminal device, where the method includes determining, by a first device, a time that the first device is out of coverage of a synchronization source after leaving the coverage of the synchronization source determining, by the first device, target timing based on the time, and performing, by the first device, D2D communication based on the target timing. Hence, the target timing can be selected more accurately for the first device.

Abstract: A data transmission method, device, and system to resolve a problem that encoding cannot be performed based on an incomplete subframe because a length of the incomplete subframe is unknown. A first device generates a first subframe and a second subframe according to first data, determines a redundancy version (RV) of the first subframe according to an RV of the second subframe, and sends M of N orthogonal frequency division multiplexing (OFDM) symbols of the first subframe and N OFDM symbols of the second subframe to a second device.

Abstract: A method includes receiving, by a core network entity, a first message from a first terminal. When the core network entity determines, according to the first message, that the first terminal is allowed to associate with a second terminal, a second message is generated by the core network entity and sent to the first terminal, where the second message is used to establish an association between the first terminal and the second terminal.

Abstract: The present invention discloses a data retransmission method, a device, and a system, and relates to the communications field, so as to resolve a prior-art problem that when a device transmits data by using an unlicensed carrier, the data cannot be retransmitted because a channel needs to be preempted again. A specific solution is as follows: A first device transmits data to a second device by using a first carrier, where the first carrier is an unlicensed carrier. The first device obtains status information of the first carrier, where the status information is used to determine whether the first carrier is available. When the first carrier is unavailable, the first device retransmits the data to the second device by using a second carrier, where the first carrier and the second carrier are different carriers. The present invention is used for data retransmission.
