Abstract: The present disclosure discloses example power control methods and apparatuses. One example method includes determining a transmit power of a control channel and a first data subchannel, where the control channel and the first data subchannel completely overlap in time domain and do not overlap in frequency domain. A transmit power of a second data subchannel is determined to be the same as the transmit power of the control channel and the first data subchannel, where the second data subchannel and the control channel overlap in frequency domain and do not overlap in time domain. The control channel and the first data subchannel are sent to a second terminal apparatus at the transmit power of the control channel and the first data subchannel. The second data subchannel is sent to the second terminal apparatus at the transmit power of the control channel and the first data subchannel.

Abstract: This application provides example communication methods and example terminal apparatuses. One example method includes obtaining, by a first terminal apparatus, resource pool configuration information, where the resource pool configuration information includes information about a physical sidelink control channel (PSCCH) time domain resource. The first terminal apparatus can then determine a PSCCH frequency domain resource based on the resource pool configuration information and a format of control information. The first terminal apparatus can then send the control information to a second terminal apparatus, where the control information is carried on a PSCCH time-frequency resource, and where the PSCCH time-frequency resource includes the PSCCH time domain resource and the PSCCH frequency domain resource.

Abstract: A sidelink resource determining method includes determining, by a first terminal device, a first sidelink candidate resource through monitoring. The method also includes receiving, by the first terminal device, at least one piece of resource indication information from a second terminal device. The at least one piece of resource indication information indicates at least one second sidelink candidate resource obtained by the second terminal device through monitoring. The method further includes determining, by the first terminal device, a sidelink sending resource based on the first sidelink candidate resource and based on the at least one second sidelink candidate resource. The method additionally includes sending, by the first terminal device, sidelink control information and data on the sidelink sending resource.

Abstract: This application may be applied to an internet of vehicles, for example, V2X, LTE-V, and V2V. A first terminal device obtains a first time-frequency resource, where the first time-frequency resource is used to send sidelink control information and data. The first terminal device sends, on the first time-frequency resource, a sidelink reference signal, the sidelink control information, and the data to a second terminal device, where the sidelink reference signal is used to determine a channel status of a sidelink between the first terminal device and the second terminal device. According to the sidelink reference signal transmission method provided in this application, the sidelink reference signal is carried on the time-frequency resource used to send the sidelink control information and/or the data, and is sent together with the sidelink control information and/or the data.

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.
