Abstract: Embodiments of this application provide a random access method including: A terminal side device obtains first uplink data from a first message buffer, where the first message buffer is a buffer specific to a first random access procedure, the first random access procedure is a procedure in which the terminal side device sends a first random access request, sends first uplink data on a first uplink resource, and receives response information, and the response information is a first random access response to the first random access request or a response to the first uplink data. The terminal side device sends the first random access request to a network side device, and sends the first uplink data to the network side device on the first uplink resource. The terminal side device detects downlink control information, where the downlink control information indicates a resource of the response information.

Abstract: A random access method and apparatus are provided. In the method, a configuration information element indicating a quantity of downlink signals per random access occasion and a first indication indicating a first downlink signal are sent by a network device to a terminal, and the terminal determines a correspondence between the first downlink signal and a random access occasion is determined based on the configuration information element, and sends a random access preamble via a random access occasion corresponding to the first downlink signal . In this way, the first random access occasion can be relatively accurately determined, and then a random access resource used for random access can be relatively precisely determined.

Abstract: This application provides a reflective QoS flow characteristic-based communications method and apparatus. In the method, an access-network network element sends first information to a core-network network element, where the first information is used to indicate whether a data packet has a reflective QoS flow characteristic; and the access-network network element determines, based on the first information, whether there is a need to send a QoS flow identifier to a terminal. In this way, signaling overheads are reduced.

Abstract: A positioning method, an apparatus, a storage medium, and a chip are provided, and relate to the field of communication technologies, to position a terminal device that is in an RRC inactive state and that reselects a target access network device. The terminal device in the RRC inactive state may move, for example, move from a first access network device to a cell of a second access network device. After receiving first information from a location management network element, the first access network device may send second information to an access network device. The first information is used to request to determine a reference signal resource for the terminal device, and the second information indicates to determine the reference signal resource for the terminal device.

Abstract: An example communication method includes determining that a first condition and a third condition are satisfied. The first condition is that preconfigured measurement information is configured and that at least one set of measurement information in the preconfigured measurement information satisfies a measurement requirement. The third condition is that measurement information of a positioning reference signal is not configured, or the third condition is that measurement information of a positioning reference signal does not satisfy the measurement requirement. The measurement information includes measurement gap (MG) configuration information. The method further includes sending a first request message. The first request message is for requesting to activate the at least one set of measurement information in the preconfigured measurement information.

Abstract: A sensing method includes determining, by a first communication apparatus, first information. The first information indicates a pulse repetition interval (PRI). The sensing method also includes sending, by the first communication apparatus, the first information to a second communication apparatus. The first information is used by the second communication apparatus to send a reference signal, and a periodicity of the reference signal in time domain is less than or equal to the PRI. The sensing method further includes receiving, by the first communication apparatus, the reference signal from the second communication apparatus. The sending method additionally includes sensing, by the first communication apparatus, a to-be-sensed target based on the reference signal.

Abstract: This application discloses a communication method and apparatus. In the method, a terminal device receives first configuration information from an access network device, where the first configuration information is for configuring M configured grant (CG) resources to correspond N downlink reference signals. The M CG resources are used by the terminal device to send uplink information when the terminal device is in a non-connected state. The terminal device then receives first reconfiguration information from the access network device after the terminal device enters the non-connected state, where the first reconfiguration information is for updating downlink reference signals corresponding to some or all of the M CG resources.
