Abstract: A communication method and a communication apparatus are provided. The method includes: A first terminal device sends data to a second terminal device over a plurality of carriers through a sidelink SL. The first terminal device determines feedback reception situations for the data on feedback reception occasions over the plurality of carriers, where the feedback reception occasion is a feedback reception occasion for the data. The first terminal device determines, based on the feedback reception situations, whether an SL radio link failure RLF occurs between the first terminal device and the second terminal device. According to this application, the SL RLF can be processed when transmission with one PC5-RRC connection is performed over the plurality of carriers.

Abstract: This application relates to a communication method and system. A first network element receives information about downlink data from a second network element, where the downlink data is from a core network device. The first network element is a first DU, and the second network element is a first CU; or the first network element is a first CU-CP, and the second network element is a first CU-UP. If the downlink data meets a downlink small data transmission condition, the first network element sends a paging message that indicates a terminal device to initiate a downlink small data transmission procedure. For example, the first network element is a DU, and the downlink data from the core network device may reach a CU.

Abstract: This application provides a radio resource control (RRC) message sending method and an apparatus. According to the method, a distributed unit (DU) determines not to start an RLC polling mechanism when sending an RRC message to a terminal device, so that when sending the RRC message to UE, the DU sets a polling bit in a header of an RLC PDU carrying the RRC message to be in an inactive state. Therefore, after receiving the RRC message, the terminal device does not feed back an RLC status report to the DU. Therefore, the terminal device does not need to initiate a random access procedure to obtain an uplink transmission resource for sending the RLC status report to the DU, thereby saving random access resources.

Abstract: This application provides a paging method and a communications apparatus. In the method, a first access network device may determine, based on grouping capability information of a first terminal device and a grouping manner supported by the first access network device for use, a first manner for paging the first terminal device. When determining the first manner, the first access network device considers the grouping capability information of the first terminal device. In this way, the determined first manner is a grouping manner supported by the first terminal device.

Abstract: A method for determining a feedback resource in a sidelink includes a first terminal sending SCI to a second terminal, where the SCI includes indication information. The indication information is used to indicate a first resource or a first resource window to be occupied for sending hybrid automatic repeat request HARQ feedback information by the second terminal, and the first resource window includes a plurality of candidate first resources. The method further includes the first terminal receiving, on the first resource, the HARQ feedback information sent by the second terminal, or monitors, in the first resource window, the HARQ feedback information sent by the second terminal.
