摘要： Embodiments of this application provide a duplication (duplication) mode communication processing method in a central unit-distributed unit (CU-DU) architecture. In a possible implementation, in a process of establishing a user plane tunnel between a CU and a DU by exchanging information about uplink tunnel endpoints and information about downlink tunnel endpoints, the DU provides an identity of a primary path to the CU, thereby implementing a duplication mode of a data radio bearer.

摘要： This application provides a unicast communication method and apparatus. The method includes: A first relay device receives a first message sent by a first terminal device, where the first message includes a first identifier of a second terminal device. The first relay device sends a second message to the second terminal device when transmission quality of the first message meets a first preset condition, where the second message is for establishing a first unicast connection, and the first unicast connection is a unicast connection established between the first terminal device and the second terminal device through the first relay device. According to the unicast communication method provided in this application, an appropriate relay device is selected in a unicast connection establishment process. This helps improve a success rate of the unicast connection and communication quality of unicast communication.

摘要： Embodiments of this application provide a communication method and a related device. The method includes: User equipment obtains various conditions based on configuration information from a base station, and then performs path switching based on the various conditions. For example, a network device first sends the configuration information to the user equipment, and then the user equipment obtains a first condition based on the configuration information. Then, in a measurement process, the user equipment sends a measurement report to the network device when determining that the first condition is currently met. After obtaining the measurement report, the network device indicates at least one candidate relay device to the user equipment by using a path switch command. The user equipment determines one relay device in the at least one candidate relay device, and communicates with the network device or another network device through the determined relay device.

摘要： This application provides a communication method, a network device, and a terminal. The communication method includes: determining, by a first network device, at least one candidate target cell and first configuration information, where the first configuration information is used to trigger a terminal to determine one of the at least one candidate target cell as a to-be-handed-over-to cell, and the first network device is a network device to which a serving cell currently accessed by the terminal belongs; and sending, by the first network device, a first message to the terminal, where the first message includes first cell indication information and the first configuration information, and the first cell indication information is used to indicate the at least one candidate target cell. The communication method, the network device, and the terminal provided in this application can increase a handover success rate of a terminal, thereby improving communication quality of the terminal.

摘要： This application discloses a communication method, including: An access network device generates a candidate conditional handover configuration group, and sends the candidate conditional handover configuration group to a terminal, where the candidate conditional handover configuration group includes one or more candidate conditional handover configurations, and the one or more candidate conditional handover configurations correspond to a flight-related parameter of the terminal; and the terminal obtains a current flight parameter, and determines a target conditional handover configuration from the candidate conditional handover configuration group based on the current flight parameter, where the target conditional handover configuration is used to determine a second cell that the terminal expects to access. In this process, because the candidate conditional handover configuration group generated by the access network device to which a first cell belongs corresponds to the flight-related parameter, the terminal obtains the target conditional handover configuration in the candidate conditional handover configuration group based on a matching result between the current flight parameter and the flight-related parameter. In this way, accuracy of obtaining the target conditional handover configuration is improved, and efficiency of handover to the second cell is improved.

摘要： This application provides a communication method and an apparatus. The method may include: A terminal device determines height information, where a first parameter is related to the height information. The terminal device receives configuration information from a first network device, where the configuration information includes a correspondence between the height information and the first parameter. The terminal device determines, based on the height information, the first parameter corresponding to the terminal device. The first parameter includes one or more of a tracking area parameter, a radio access network notification area parameter, a cell selection or reselection parameter, and a measurement configuration parameter. According to the foregoing method, configuration information corresponding to a height of an uncrewed aerial vehicle is provided, to ensure that an uncrewed aerial vehicle terminal device at a high height can obtain an effective configuration parameter, so that user experience at different heights is improved.

摘要： This application provides a communication method and a communications apparatus, including: An access layer of a terminal device receives first information that is sent by an upper layer and is used to identify a first QoS flow. When the access layer determines that the first QoS flow is a new QoS flow for which sidelink communication needs to be performed, or when the access layer determines that the first QoS flow is a new QoS flow for which sidelink communication needs to be performed and no mapping relationship from the first QoS flow to an SLRB is configured, or when the access layer determines that no mapping relationship from the first QoS flow to a sidelink radio bearer SLRB is configured, the terminal device reports first QoS information to a network device, to request SLRB configuration information associated with the first QoS flow. The foregoing solutions clearly define a condition for triggering reporting of QoS information, so that the terminal device can report the QoS information on a proper occasion, to obtain the corresponding SLRB configuration information.
