Abstract: A self-contained subframe configuration method includes obtaining configuration information of a self-contained subframe of a current frequency band based on a subframe transmission direction of a neighboring frequency band. The self-contained subframe includes a downlink control (DLcontrol) field, a first transmission subframe, a second transmission subframe, a guard period (GP), and an uplink control (ULcontrol) field. The first transmission subframe or the second transmission subframe of the self-contained subframe is transmitted in the same subframe transmission direction used during subframe transmission on the neighboring frequency band. Alternatively, the first transmission subframe or the second transmission subframe of the self-contained subframe is transmitted in a guard period of the neighboring frequency band.

Abstract: The present invention relates to the communications field, and discloses a path selection method, a device, and a system, to resolve a problem in the prior art that if a distance between two terminal devices performing direct communication is relatively long or channel quality changes relatively greatly, the two terminal devices cannot perform D2D communication. A specific solution is: A first device receives first discovery information sent by a second device, adds an ID of the first device to the first discovery information, and sends the first discovery information to which the ID of the first device is added, so that a destination device can determine a transmission path after receiving the first discovery information. The present invention is used for path selection.

Abstract: A data transmission method and a device are disclosed and relate to the field of communications technologies, so that a CSI status feedback mechanism suitable for an LTE-U system can be provided. The method includes: detecting, by a first device, data that is transmitted by a second device on an unlicensed carrier; and sending, by the first device, channel state information CSI to the second device on an Nth time resource that is after the first device starts to receive the data that is transmitted by the second device on the unlicensed carrier, where N is a positive integer less than 4. The method and the device are used for data transmission.

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.
