Abstract: An exemplary embodiment provides a transmission resource determining method and apparatus. A first terminal device obtains a slot format corresponding to at least one other terminal device in a first slot, where the slot format includes a first slot format and/or a second slot format; symbols used for sending information and receiving information in the first slot format are inconsistent with those in the second slot format. The first terminal device determines, based on the slot format corresponding to the at least one other terminal device in the first slot, a slot format corresponding to the first terminal device in the first slot. This may be applied to an Internet of Vehicles, for example, V2X, LTE-V, and V2V.

Abstract: This application provides example sidelink control information sending methods and example communications devices. One example method includes sending, by a first communications device, first sub control information to a second communications device and a third communications device, where the first sub control information is scrambled by using a common scrambling sequence, the first communications device and the second communications device belong to a first communications device group, and the third communications device does not belong to the first communications device group. The first communications device can then send second sub control information to the second communications device, where the second sub control information is scrambled by using a scrambling sequence generated by using a user equipment identifier of the second communications device or a scrambling sequence generated by using a group identifier of the first communications device group.

Abstract: Embodiments relate to the field of wireless communication technologies and provide a method for performing channel sounding, a network-side device, and a terminal. A first terminal sends a resource scheduling request to a network-side device when the first terminal starts a communication connection with a second terminal. The resource scheduling request carrying information about the second terminal requests the network-side device to allocate a transmission resource for channel sounding between the first terminal and the second terminal. The first terminal receives a sounding reference signal sent by the second terminal, and obtains information of a channel for communication between the first terminal and the second terminal. The method enables quick and effective channel sounding between terminals, thereby increasing communication efficiency between the terminals.

Abstract: The present disclosure discloses a data transmission method, device, and system. The method includes: receiving, by a cooperation device and a target device, to-be-transmitted data sent by a network side device. A first moment is defined as the moment when the target device feeds back, to the network side device, whether the to-be-transmitted data is correctly received is defined as a first moment. Before the first moment, the cooperation device is configured to send the to-be-transmitted data to the target device. And the target device is configured to receive, process and check the to-be-transmitted data sent by the cooperation device before the first moment.
