Abstract: This application provides a physical downlink control channel processing method and a related device. In the method, a search space may be determined based on a first radio network temporary identifier, where the search space is a set of M candidate physical downlink control channels; and a target physical downlink control channel is detected from the search space based on a second radio network temporary identifier, where the first radio network temporary identifier is a radio network temporary identifier of a first device or a second device, the second radio network temporary identifier is the radio network temporary identifier of the second device, first downlink control information carried by the target physical downlink control channel is information that is scrambled by using the second radio network temporary identifier and that is used to schedule the second device, and the second device communicates with a network by using the first device.

Abstract: A terminal synchronization method and a terminal relate to the communications field, where the terminal sends synchronization signals in a distributed manner by controlling a sequence for sending the synchronization signals, such that terminals in a vehicle to vehicle communications system can have uniform timing. The method includes obtaining, by a terminal, a configurable transmission period for sending a first synchronization signal, and sending, by the terminal, the first synchronization signal based on the configurable transmission period.

Abstract: Embodiments of the present invention relate to the field of communications technologies, and provide an interference cancellation apparatus and method, which can avoid being limited by a dynamic range of an ADC/DAC and can cancel a second-type self-interference component effectively. The interference cancellation apparatus includes a main receive antenna, a divider, a first-type interference canceller, a down converter, a filter, a coupler, a digital down-conversion unit, a second-type interference reconstructor, and a local-frequency signal generator. The present invention is used for interference cancellation.

Abstract: A data processing method includes communicating, by a remote terminal device, with a network device by a relay device. The communicating includes starting a timer in response to a radio resource control (RRC) connection establishment procedure of the remote terminal device being initialized. The communicating includes sending indication information to the relay terminal device in response to the timer expiring. The indication information is useable to indicate the relay terminal device not to forward data corresponding to the remote terminal device, the indication information is useable to release a unicast link between the remote terminal device and the relay terminal device, or the indication information is useable to indicate to clear a buffer corresponding to the remote terminal device.

Abstract: First configuration information is configured for a second device by a first device. The first configuration information is used to indicate a first time-frequency resource allocated by the first device. The first time-frequency resource is different from a second time-frequency resource that is allocated by the first device to a third device in a same group. The first time-frequency resource comprises a third time-frequency resource and a fourth time-frequency resource. The third time-frequency resource is a time-frequency resource used when the first device receives a message sent by the second device. The fourth time-frequency resource is a time-frequency resource used when the first device sends a message to the second device. The third time-frequency resource is different from the fourth time-frequency resource. Control information that includes the first configuration information is sent by the first device.
