Abstract: An access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value instructs a station that has accessed a channel to hand over a held TXOP to the access point, and the second value instructs the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.

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: 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 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.
