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.

Abstract: This application relates to a communication method and device. A first terminal device receives at least one message for reserving a resource, and the first terminal device determines, from S resources based on the at least one message, M resources whose signal strengths do not meet a first signal strength threshold. The first terminal device adjusts the first signal strength threshold if M does not meet a first resource quantity or S-M does not meet a first resource quantity. The first terminal device sends a first message to a second terminal device, where the first message indicates a resource determined based on an adjusted signal strength threshold, and the adjusted signal strength threshold enables M or S-M to meet the first resource quantity.

Abstract: A power saving method includes: sending, by a terminal device, first information to a network device, where the first information is used to indicate processing time for the terminal device to process to-be-processed information; and configuring, by the network device, a time domain resource for the to-be-processed information based on the first information, and sending second information to the terminal device, where the second information is used to indicate the time domain resource. After receiving the second information, the terminal device adjusts the foregoing processing time based on the time domain resource indicated by the second information, to relax a clock of each module corresponding to the processing time. Thereby, a terminal device power saving is implemented. In addition, the network device configures the time domain resource based on the processing time of the terminal device that is indicated by the first information.

Abstract: A method includes that a first terminal device sends a sidelink discontinuous reception (DRX) parameter of a second terminal device or indication information to a network device such that the network device determines a first time period based on the sidelink DRX parameter or the indication information, where the first time period belongs to sidelink DRX active time of the second terminal device. The first terminal device receives a sidelink grant sent by the network device, where the sidelink grant is used to indicate the first terminal device to send a resource of a physical sidelink control channel (PSCCH) and/or a physical sidelink shared channel (PSSCH), and a time domain position of the resource is in the first time period. The first terminal device sends a PSCCH and/or a PSSCH based on the sidelink grant.
