Abstract: This application relates to an access control method, applied to the field of short-range communication, for example, cockpit domain communication. The method includes: determining that a status of a first device is a first status; and sending first indication information, where the first indication information is used to indicate whether access of at least one second device to the first device is allowed. A system broadcast message carrying system status information is sent, so that after a non-vehicle-mounted device receives the system broadcast message, the non-vehicle-mounted device determines, based on the system status information, whether to initiate a random access request. This avoids impact, caused by random access request initiation performed by the non-vehicle-mounted device in this phase, on checking a status of a vehicle-mounted device performed by a CDC and self-check and access performed by the vehicle-mounted device.

Abstract: Embodiments of this application provide a communication method and a related apparatus, and may be applied to the field of vehicle-mounted devices, and in particular, to short-distance communication in a cockpit domain. According to embodiments of this application, an electronic device obtains at least one of identity information and priority information of a first apparatus. After determining that a priority of the first apparatus is higher than a priority of a second apparatus, the electronic device obtains first resource configuration information, where a resource configured by using the first resource configuration information is allocated by the first apparatus, and may be used for communication between the first apparatus and a third apparatus, or may be used for communication between the first apparatus and the second apparatus.

Abstract: This application provides a prompt method for fitness training and an electronic device, and relates to the field of artificial intelligence. The method includes: obtaining required training space, where the required training space is used to complete one or more training actions; determining, based on a training scenario in which a user is located and the required training space, a training location recommended to the user; and recording collecting a training action of the user based on the training location recommended to the user. A suitable training location is recommended to the user based on the training scenario in which the user is located and the required training space. Therefore, the user can also normally perform training in a scenario in which exercise space is limited, for example, when there is an obstruction or a site is insufficient.

Abstract: This application provides a direct link data transmission method, a terminal device, and a network device. The method includes: receiving, by a first terminal device, first configuration information sent by a network device, where the first configuration information includes information about a transmission resource set, and the transmission resource set is a transmission resource set shared between a second terminal device that uses a centralized scheduling transmission mode and a third terminal device that uses a distributed transmission mode; detecting, by the first terminal device, a load level of a resource unit in the transmission resource set based on the information about the transmission resource set; and sending, by the first terminal device, report information to the network device based on the load level, where the report information includes information about an occupied resource unit and/or information about an available resource unit in the transmission resource set. A transmission resource allocated to the first terminal device can be prevented from colliding with a transmission resource of another terminal device, so that communication quality of a terminal device and user experience is improved.
