Abstract: When cell system information changes, a first terminal device receives, during on duration of the first terminal device, system information sent by a second terminal device, so that the first terminal device can receive the system information through a sidelink between the first terminal device and the second terminal device without a need to maintain a cellular link, thereby reducing complexity and power consumption of system information transmission. Alternatively, when cell system information changes and a first terminal device has only one receive radio frequency chain, the first terminal device obtains system information within a gap period of communication between the second terminal device and the first terminal device through a link between the first terminal device and a network device, so that the first terminal device maintains a cellular link only within the gap period, thereby reducing complexity and power consumption of system information transmission to some extent.

Abstract: The technology of this application relates to a communication method and a communication apparatus. The method may include a terminal device receiving a first wake-up signal, where the first wake-up signal is used to wake up a terminal device group, the terminal device group includes at least two terminal devices, and the at least two terminal devices include the terminal device, and the terminal device accessing a network device based on the first wake-up signal. The network device may wake up a group of terminal devices by sending a wake-up signal. In other words, the group of terminal devices may access the network device based on the same wake-up signal. In this way, resource overheads caused by waking up the at least two terminal devices can be reduced.
