Abstract: A control information processing method and system includes: receiving, by a first device, first control information sent by a network device; determining, by the first device based on first information, that the first control information is used to schedule a target device, where the target device is one of the first device and at least one second device. The first information is related to the first control information. When the target device is at least one second device, determining, by the first device, second control information based on resource information that is used for data transmission and that is included in the first control information, and sending the second control information to the target device, so that the target device transmits data based on the second control information. When the target device is the first device, transmitting, by the first device, data based on the first control information.

Abstract: A slot scheduling method and apparatus are provided. A determined slot includes a first slot, the first slot includes a first idle time, and a time interval between a start moment of the first idle time and a start moment of the first slot is less than or equal to a preset time interval threshold, or a time interval between a start moment of the first idle time and an end moment of at least one OFDM symbol that is in the first slot and that is used to transmit control signaling is less than or equal to a preset time interval threshold. No first service is scheduled in the first idle time, thereby providing a transmission opportunity for a second service. In addition, time-domain locations of uplink transmission and downlink transmission of the first service and the second service do not overlap.

Abstract: This application discloses a signal transmission method and a related device. The method may include: sending, by a first terminal, a first message to a network device, where the first message is used to indicate a transmission mode used by the first terminal to transmit a signal; receiving a second message sent by the network device, where the second message is used to indicate a resource used by the first terminal to transmit the signal; and transmitting the signal on the resource. According to the foregoing solution, a terminal may transmit a signal by using different transmission modes and resources.

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.
