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 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.

Abstract: This application provides an information transmission method and apparatus. The method includes: generating, by a network device, first information; and sending, by the network device, the first information to a terminal device, where the first information is used to instruct the terminal device to detect at least one group common PDCCH on N component carriers CCs, N is a positive integer and is less than or equal to M, M is a quantity of CCs configured for the terminal device, and M is a positive integer. Based on this, after receiving the first information, the terminal device detects the at least one group common PDCCH on the N CCs according to the first information.

Abstract: A resource indication method includes generating, by a network device, first control information, where the first control information is used to indicate a frequency resource occupied to transmit data in N time resource units, and N is a positive integer greater than or equal to 2; and sending, by the network device, the first control information to a terminal device. Therefore, the network device may indicate, for the scheduled N time resource units, the frequency resource occupied to transmit data in the N time resource units.

Abstract: A communication method and a communications device are disclosed. A first device in a communications system separately sends, to a second device, responses used to indicate a transmission result of target data: a first response and a second response. An indication manner of the first response is different from an indication manner of the second response. This approach can improve flexibility of a response indication manner. Therefore, the communications system can flexibly adjust indication manners of responses sent at different times to ensure indication precision of the responses while reducing transmission resources of the responses.

Abstract: This application provides a method that includes the step of receiving, by a first device in a first time domain position, first scheduling information. The first scheduling information includes first indication information sent by a network device, wherein the first indication information is used to indicate a first interval. The method further comprises sending, by the first device, second scheduling information including second indication information to a second device in a second time domain position, wherein the second indication information is used to indicate a second interval, which is the difference between the first interval and a third interval. The second scheduling information is used by the second device to determine the target time domain position used by the second device to determine a time domain resource used to send and/or receive data.
