Abstract: A data feedback method is described. The method includes a second terminal sending first feedback information to a first terminal based on a sidelink. The first terminal determines, based on a receiving result of the first terminal for first data and a receiving result that is of the second terminal and that is indicated by the first feedback information, second feedback information that is sent to a network device. In this way, an energy saving requirement of the second terminal is met. Moreover, the described method ensures the network device can also determine receiving results of the first terminal and the second terminal based on the second feedback information, thereby reducing unnecessary operations performed by the network device.

Abstract: An information sending method, an information receiving method, a device, and an apparatus are disclosed. The information sending method includes: determining, by a first terminal device based on first information, at least one of a quantity or a position of m DMRSs carried on a PSSCH, where m is a positive integer, and the first information includes at least one of a subcarrier spacing, duration of the PSSCH, or a channel coherence time; and sending, by the first terminal device, the m DMRSs to a second terminal device. In addition, when the DMRS on the PSSCH is determined, a reference channel coherence time may be selected. For example, a time interval between two configured adjacent DMRSs may be less than or equal to the channel coherence time.

Abstract: The present disclosure relates to feedback channel sending methods. In one example method, a first terminal device obtains configuration information of a resource pool, where the configuration information is used to indicate that frequency domain resources of the resource pool include L sub-channels and each sub-channel includes q resource blocks (RBs), M of the L sub-channels are used by the first terminal device to send at least one of a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH), N of the L sub-channels are used by the first terminal device to receive a physical sidelink feedback channel (PSFCH) from a second terminal device, and there is a correspondence between one of the M sub-channels and one of N·q RBs included in the N sub-channels, and sends at least one of a first PSCCH or a first PSSCH on a first channel in a slot n.

Abstract: When a quantity of radio resources available for a terminal device is less than a quantity of required radio resources, the terminal device sends a request to another terminal device, to request the another terminal device to release at least one radio resource currently used by the another terminal device or reselect a radio resource. The another terminal device that receives the request may autonomously release or request a network to release the at least one radio resource currently used by the another terminal device, or autonomously reselect or request a network to reselect the radio resource, and send a response to the terminal that sends the request. Nonconsecutive fragmented radio resources may be integrated into consecutive and relatively large radio resources, so that radio resource fragments are reduced, and the terminal device can send control information and data in a timely manner, thereby improving radio resource utilization.

Abstract: This application provides a communication method and apparatus used for the internet of vehicles, for example, vehicle to everything (V2X), Long Term Evolution-Vehicle (LTE-V), and vehicle-to-vehicle communication (V2V). The method includes: a first terminal apparatus generates, based on indication information such as an aggregation level of a control channel or a demodulation reference sequence configuration of a data channel, a demodulation reference sequence of another control channel, and sends the demodulation reference sequence to a second terminal apparatus. The second terminal apparatus can obtain the indication information in a process of detecting the demodulation reference sequence of the other control channel, to demodulate the control channel or the data channel.

Abstract: This application provides a method for determining a transport block size and a communication apparatus, which may be used in systems such as vehicle-to-everything, V2X, and V2V. A receive-end terminal device and a transmit-end terminal device may determine a quantity of encoded symbols based on a symbol length used for sidelink communication in a time unit and an scaling factor, and may further determine a transport block size of a data channel based on the quantity of encoded symbols. Therefore, for all slots used for sidelink communication, a same quantity of encoded symbols can be determined, and a same transport block size can be further determined.

Abstract: Example response information sending and receiving methods and apparatus are described. One example sending method includes receiving first indication information by a first communications device from a network device, where the first indication information is used to indicate a first resource for transmitting first data. The first communications device sends the first data to a second communications device on the first resource. The first communications device receives second indication information from the network device, where the second indication information is used to indicate a second resource for transmitting response information of the first data. The second source and the first resource do not include a same resource. The first communications device receives the response information of the first data from the second communications device on the second resource.
