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: A sidelink communication method, a terminal device, and a network device are provided. In some embodiments, a terminal device receives resource configuration information sent by a network device, where the resource configuration information is for configuring a common resource for the terminal device, and the common resource is a resource that is configured by the network device for all terminal devices within coverage of the network device and that is to be used by all the terminal devices to perform sidelink communication. The terminal device receives sidelink BWP indication information sent by the network device, where the sidelink BWP indication information indicates N sidelink bandwidth parts SL-BWPs, and the N SL-BWPs include a frequency domain resource corresponding to the common resource, where N is a positive integer. The terminal device performs sidelink communication with another terminal device in the N SL-BWPs.

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.
