Abstract: A transmission parameter obtaining method includes obtaining, by a terminal device, a transmission parameter of a network device, wherein the transmission parameter indicates location information of the network device. The method also includes determining, by the terminal device, at least one of an intra-frequency cell-reselection measurement threshold or an inter-frequency cell-reselection measurement threshold based on the transmission parameter. The method further includes determining, by the terminal device, a radio link failure threshold based on the transmission parameter. The method additionally includes determining, by the terminal device, at least one of an intra-frequency connected-state measurement threshold or an inter-frequency connected-state measurement threshold based on the transmission parameter.

Abstract: A network device sends multicast configuration information to a terminal device, where the multicast configuration information corresponds to a first multicast service, the multicast configuration information includes first indication information, and the first indication information indicates that the terminal device sends first feedback information for the first multicast service. The terminal device receives the first multicast service based on the first multicast configuration information, and then sends the first feedback information corresponding to the first multicast service to the network device based on the first indication information in the first multicast configuration information. The feedback mechanism applies to a multicast transmission technology and improves transmission reliability of a multicast service.

Abstract: This application provides a communication method and a related apparatus, which are applied to the multicast field, and in particular, relate to a multimedia broadcast multicast service MBMS. In this method, a terminal device receives, from a target base station to which the terminal device is handed over, at least one first data packet that is of a first service and that is sent in a transmission mode, and receives first indication information from the first base station. The terminal device sends a part of or all data packets in the at least one first data packet to an upper layer entity of the terminal device based on the first indication information.

Abstract: This application provides a communication method and a related apparatus, and is applied to the multicast field. One example method includes: A first terminal device obtains a first multicast configuration parameter, where the first multicast configuration parameter includes a group radio network temporary identifier (G-RNTI) and an identifier of a multicast service. The first terminal device in an idle state or an inactive state receives the multicast service based on the first multicast configuration parameter.

Abstract: This application provides a communication method and apparatus. An example method includes: A first core network device generates first information, and sends the first information to a first access network device, where the first information is used to indicate a service type and/or a service priority of a first service, the first service is a service of a first terminal device in a radio resource control (RRC) inactive state, and the first access network device is an anchor access network device of the first terminal device. The first core network device sends the first access network device the first information used to indicate the service type and/or the service priority of the first service of the first terminal device, so that the service type and/or the service priority of the first service may be carried when the first access network device pages the first terminal device.

Abstract: The present invention provides an uplink reference signal sending method, and the method includes: sending, by a terminal device, an uplink reference signal on N1 second component carriers within a determined uplink reference signal sending time, and prohibiting, on M1 first component carriers in M first component carriers within the sending time, the terminal device from sending an uplink signal, where the first component carriers are carriers on which scheduling of uplink data transmission is allowed, and the second component carriers are carriers on which scheduling of uplink data transmission is prohibited. N1=M1, in other words, within the sending time, a quantity N1 of second component carriers on which the uplink reference signal is sent is less than or equal to a quantity M1 of first component carriers on which sending of the uplink signal is prohibited.
