Abstract: This application provides a communication method and apparatus, to help ensure a transmission reliability and/or communication range requirement. When configuring a transmission resource of a sidelink for a terminal, a network device also configures attribute information of the transmission resource. The attribute information may indicate reliability and/or a communication range corresponding to the transmission resource. The terminal device may select a matched logical channel for the transmission resource based on the attribute information of the transmission resource and attribute information of each logical channel of the terminal device. The attribute information of the logical channel is used to indicate reliability and/or a communication range of the logical channel.

Abstract: This application provides a communication method, so that sidelink signaling can be used for transmission of AS configuration information. Specifically, a first terminal device obtains a source identifier allocated to groupcast communication by a second terminal device, where the groupcast communication is communication for a target group, and the first terminal device and the second terminal device belong to the target group. A V2X layer of the first terminal device generates first sidelink signaling, and sends the first sidelink signaling, a first identifier, and a group identifier to an AS of the first terminal device, where the first identifier is a source identifier allocated to the groupcast communication by the first terminal device, and the group identifier is used to identify the target group. The AS sends the first sidelink signaling by using the first identifier as a source identifier and using the group identifier as a destination identifier.

Abstract: The present disclosure relates to information transmission methods. In one example method, a first network device or a second network device triggers a terminal device to be handed over from a first cell to a second cell. The terminal device sends second information, where the second information includes information about a radio link failure that occurs between the terminal device and the second cell, or information about beam failure recovery that occurs between the terminal device and the second cell. The first network device or the second network device performs mobility robustness optimization based on the second information.

Abstract: This application discloses a signal transmission method. The method may include: A core network delivers two sets of QoS parameters to an access network device. The access network device selects one of the two sets of QoS parameters, and indicates the selected set of QoS parameters to the core network. An air interface rate required by the set of QoS parameters can be supported by a RAN. In this way, a QoS parameter applied to related UE, a related bearer, a related PDU session, or a related QoS flow can be effectively determined, and a board capability of an LTE base station does not need to be upgraded. In addition, the core network may set, based on a QoS parameter selected by a RAN side, a corresponding QoS management policy such as a rate adjustment policy, to facilitate data transmission between UE and the core network.
