Abstract: This application provides a sidelink feedback information transmission method and a communication apparatus. The method includes: A first terminal sends first indication information to a second terminal, where the first indication information indicates that first channel occupancy time includes a first physical sidelink feedback channel PSFCH resource; and the first terminal receives, on the first PSFCH resource, feedback information from the second terminal. In this application, the second terminal sends the feedback information by using a resource contended by the first terminal. Compared with a solution in which the second terminal contends for a resource to send the feedback information, this solution in this application can reduce a possibility of a contention failure of the second terminal, and improve accuracy of data transmission.

Abstract: This application relates to the field of wireless communications technologies, and provides a method for communication between terminals, a network-side device, and a terminal. The method discloses that the network-side device allocates, to the terminal, time-frequency resources for transmitting uplink information and sidelink information. On the time-frequency resources and at a same moment in a range of time domain-frequency resources, the terminal transmits the uplink information used for performing uplink beamform training to the network-side device, and transmits the sidelink information used for performing sidelink beamform training to another terminal. According to solutions provided in this application, based on conventional uplink and downlink beamform training procedures, the terminal performs the sidelink beamform training without additionally using a new time-frequency resource.

Abstract: This application discloses a resource configuration method and a communication apparatus, and is applicable to fields such as V2X, internet of vehicles, intelligent driving, or intelligent connected vehicles. The method includes: A first terminal apparatus obtains first configuration information, and sends resource occupation information to a network apparatus. The first configuration information may indicate a first resource pool, and the first resource pool is used by the first terminal apparatus to send first information. The resource occupation information may indicate resource occupation of a second information set in the first resource pool. In this way, the network device flexibly adjusts, based on the actual occupation, of allocated resources, by the second information, resources configured for a terminal device that transmits the first information and a terminal device that transmits the second information, to improve resource utilization.

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.
