Abstract: This application provides a communication method and a communication apparatus. The method performed by a relay terminal includes: determining that a network accessed by the relay terminal supports an emergency service, and sending a first message for a remote terminal discovering the relay terminal. The first message is a first discovery message including a relay service code corresponding to the emergency service; or the first message is a response message to a second discovery message including a relay service code corresponding to the emergency service from the remote terminal. This method can ensure that a network accessed by a relay terminal participating in a relay discovery procedure of the emergency service supports the emergency service, thereby ensuring that a relay terminal selected by a remote terminal that expects to access the emergency service can provide a relay service for the emergency service.

Abstract: The present disclosure provides a communication method and apparatus. The method may include: A terminal device receives a first timer from a network device that indicates a first duration after which the terminal device initiates periodic connection establishment to the network device. The first duration is greater than or equal to a duration of the terminal device in a non-coverage area of a satellite. The terminal device activates the first timer when the terminal device determines that the terminal device leaves a coverage area of the satellite.

Abstract: Embodiments of the present application propose a feedback method for an uplink channel, and an apparatus. In the solution, instead of always sending a first common message or a first scheduling command in any case, a base station determines, only after determining whether a data packet to be sent by a terminal is the last data packet of the terminal, whether a to-be-sent message including an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal is the first scheduling command or the first common message. Alternatively, when the base station determines that the terminal needs to send a next data packet or needs to retransmit the data packet, an indication bit for the terminal in at least two indication bits is used to indicate uplink control information. Therefore, this avoids a waste of resources.

Abstract: Embodiments of the present invention disclose a control information sending method, a control information detection method, a base station, and user equipment. The control information sending method includes: determining, by a base station, target control information and characteristic information corresponding to the target control information, where the target control information is information for scheduling target user equipment by the base station; determining, according to a preset rule and the characteristic information from a resource block set corresponding to a target coverage level, a target resource block subset corresponding to the target control information, and selecting, from the target resource block subset, an available resource block as a target resource block; and sending the target control information using the target resource block.
