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: Embodiments of the present invention provide an uplink transmission method and an apparatus. When a first data packet and a second data packet are simultaneously transmitted, UE maps the first data packet to a first time-frequency resource of a time-frequency resource block, maps the second data packet to a second time-frequency resource of the time-frequency resource block, sends the first data packet and the second data packet by using different time-frequency resources of the same time-frequency resource block, and feeds back a receiving result of the first data packet and the second data packet by using a new feedback mechanism. In this way, a conflict between an initially transmitted data packet and a retransmitted data packet in an SPS scenario can be avoided, and time-frequency resources can be more effectively used.

Abstract: In a communication method, a first communication apparatus obtains first configuration information of a first signal, where the first configuration information is associated with a first communication procedure of the first communication apparatus. The first communication apparatus obtains second configuration information of the first signal, where the second configuration information is associated with a second communication procedure of the first communication apparatus. The first communication apparatus sends the first signal based on at least one of the first configuration information or the second configuration information. In this way, the first communication apparatus can use a same type of signals to perform different communication procedures. This reduces processing complexity, and can further reduce chip costs of the first communication apparatus and improve resource utilization.

Abstract: A first access network device (AND) sends a first message to a second AND. The first message is usable to request to hand over a group of terminal devices under the first AND to the second AND. The group of terminal devices includes one or more terminal devices. In response to the first AND receiving a first response message from the second AND for the first message, the first AND sends a second message to the terminal devices. The first response message is usable to indicate that the terminal devices are allowed to be handed over to the second AND, and the second message is usable to indicate the terminal devices to be handed over to the second AND. After the terminal devices are handed over to the second AND, the first AND switches off one or more cells.

Abstract: Embodiments provide a communication method, a network device, and a terminal device. Under the method, a network device can send SRS configuration information of a first transmission resource and of a second transmission resource to a terminal device. The first transmission resource is a switching source carrier or bandwidth part. The second transmission resource is a switching destination carrier or bandwidth part. The SRS configuration information of the first and second transmission resource includes a first OFDM symbol set and a second OFDM symbol set respectively. Some and all symbols in the first set and second set may be used by the terminal device to send an SRS on the first and second transmission resource respectively. In various embodiments, the network device configures one or more symbols for the terminal device to transmit an SRS, so that high-frequency channel measurement can be better supported.
