Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: A random access method includes working, by a user equipment (UE), on a first bandwidth part (BWP), where the first BWP is a currently active BWP, when the UE needs to perform a random access procedure, the UE performs the random access procedure on an initial BWP or on the first BWP, and when the UE receives BWP switching indication information from a network device instructing the UE to use a second BWP when performing the random access procedure on the first BWP, continuing, by the UE, to perform the random access procedure on the first BWP, or stopping, by the UE, performing the random access procedure on the first BWP, and performing the random access procedure on the second BWP.

Abstract: This application provides a communications method and apparatus. The method includes: obtaining, by a media access control (MAC) entity, M radio link control (RLC) protocol data units PDUs, where M is an integer greater than or equal to 2; and generating, by the MAC entity, N media access control MAC protocol data units (PDUs) based on a logical channel corresponding to each of the M RLC PDUs, where any two RLC PDUs corresponding to a same logical channel and having consecutive RLC sequence numbers are carried in different MAC PDUs, and N is an integer greater than or equal to 2. Consecutive RLC PDUs are placed into different MAC PDUs, so that a continuous packet loss of a same service can be avoided, and transmission reliability can be improved.

Abstract: The present disclosure relates to data transmission methods, network devices, and terminal devices. One example data transmission method includes receiving, by a first network node, a first report from a terminal device, where the first report is used to indicate an uplink data volume of a buffer of the terminal device, and sending, by the first network node, first indication information to a second network node, where the first indication information includes information about the uplink data volume of the buffer of the terminal device, or the first indication information is used to indicate a relationship between the uplink data volume of the buffer of the terminal device and a predefined data volume threshold.

Abstract: A data transmission, by a terminal device, is described that improves data transmission efficiency while ensuring a transmission latency. The data transmission method includes sending a first transport block to a radio access device for X times by using a shared resource that is configured by the radio access device for at least one terminal, where the terminal is one of the at least one terminal, and X>0. The method further includes determining a dedicated resource allocated by the radio access device to the terminal, and sending the first transport block to the radio access device for Y times by using a target resource. The target resource includes the dedicated resource, and Y≥0.

Abstract: A communication method is provided. In the method, if a first logical channel of a terminal device does not have an uplink resource for carrying a scheduling request (SR) and the terminal device is in a first SR state, remaining, by the terminal device, in the first SR state and/or a first buffer status report (BSR) state until data of the first logical channel and/or a BSR are/is sent, where the BSR is used to indicate buffer status information of a logical channel group including the first logical channel. When a logical channel of the terminal device does not have an uplink resource for carrying the scheduling request, a problem that the terminal device cannot obtain an uplink transmission resource can be resolved.

Abstract: Embodiments of this application provide a resource scheduling method, which includes: transmitting, by a terminal device, at least first indication information to a network device on a pre-allocated uplink resource, where the first indication information indicates a data volume of to-be-transmitted data of the terminal device; and transmitting the to-be-transmitted data on an uplink resource if the terminal device receives at least second indication information transmitted by the network device, where the second indication information indicates the uplink resource allocated by the network device to the terminal device. In the embodiments of this application, when to-be-transmitted data is MBB service data, the terminal device may transmit a data volume of the MBB service data to the network device on a grant-free resource, so that the network device allocates an uplink resource to the terminal device and the terminal device transmits the MBB service data on the uplink resource.

Abstract: Embodiments disclose a random access method, a device, and a system, and relate to the field of communications technologies, to resolve a problem of how to implement network access when two or more uplink frequency bands exist in a 5G system. A specific solution is as follows: A terminal receives, from an access network device, random access configurations corresponding to at least two uplink frequency bands, and initiates random access based on at least one of the random access configurations corresponding to the at least two uplink frequency bands. The embodiments are used for a random access process.

Abstract: A method, an apparatus, and a system for implementing data scheduling are provided. According to the application, a buffer status report (BSR) is generated when uplink data that needs to be sent exists; and by using the BSR and correspondence between a logical channel and a base station, a UE transmits the uplink data on a logical channel that corresponds to a base station, thereby avoiding a problem that data cannot be processed because a radio resource and a logical channel correspond to different base stations. Accordingly, the UE can transfer data to be uploaded to a correct base station corresponding thereto, which greatly improves efficiency of data scheduling in a mode of carrier aggregation between base stations.
