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: 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 a 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. In this way, initial transmission or retransmission of a transport block can be performed in each slot used for sidelink communication, to avoid a limitation on selection of a transmission resource and a resulting transmission delay.

Abstract: In a method for resource determination for sidelink communications, a first terminal apparatus determines an available time-frequency resource set in a resource selection window based on resource reservation information of a second terminal apparatus and a first channel occupancy time. The first channel occupancy time is shared by the first terminal apparatus and the second terminal apparatus. When a time-frequency resource occupied by another terminal apparatus during resource selection is excluded, the first terminal apparatus does not need to exclude a time-frequency resource unit reserved by that other terminal apparatus except when it is the second terminal apparatus, to prevent excessive time-frequency resource units from being excluded.
