Abstract: Embodiments of the present invention provide a resource allocation method and apparatus. A central control node determines a target backhaul node for a normal small cell from M candidate backhaul nodes and communication link resource information between the normal small cell and the target backhaul node based on access link resource pre-occupation information of the normal small cell, link quality information between the normal small cell and each of the M candidate backhaul nodes, and available backhaul link resource information sent by the M candidate backhaul nodes.

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: The present disclosure relates to communications methods and apparatuses. One example method includes receiving first indication information sent by a network device, where the first indication information is used to indicate a first time-frequency resource, generating first data based on a resource attribute of the first time-frequency resource, where the first data includes data of at least one logical channel, and sending the first data to the network device on the first time-frequency resource. The method may be applied to the internet of vehicles, for example, vehicle-to-everything (V2X), long term evolution-vehicle (LTE-V), and vehicle-to-vehicle (V2V).

Abstract: This application provides an access method and a communication apparatus, applied to the communication field, and in particular, to the field of short-range communication. The access method includes: sending first broadcast information based on a target access mode, where the first broadcast information indicates that a broadcast type is connectable; and if a first access request from a first device is received within first preset duration, sending first response information for the first access request, where the target access mode is an access mode in an access mode set, and the access mode set includes at least two access modes. Through configuration of the at least two access modes, access modes can be selected in different scenarios, to shorten time for subsequently establishing a connection between the first device and a second device, reduce power consumption of the first device or the second device.

Abstract: Embodiments of this disclosure provide a connection configuration method and apparatus, and relate to the field of communication technologies. The method includes: obtaining device information of at least one second device; and generating topology information based on the device information of the at least one second device, where the topology information indicates a connection relationship between a first device and the at least one second device or a connection relationship between the at least one second device, and the connection relationship indicates a priority of a device and/or a master-slave relationship between devices. In this way, efficiency and convenience of connection configuration of a plurality of short-distance devices can be improved.
