Abstract: A control signaling processing method, a device, and a system relate to the field of communications technologies, to perform integrity protection on control signaling exchanged between a DU and UE in a CU-DU separated access network architecture. The method includes: determining, by a DU, integrity protection parameters and an integrity protection algorithm, where the integrity protection parameters and the integrity protection algorithm are used to perform integrity protection on a signaling radio bearer between the DU and UE; determining, by the DU, a message authentication code MAC-I based on the integrity protection parameters and the integrity protection algorithm; and receiving, by the DU, control signaling sent by an RRC layer of the DU, and sending, to the UE, the control signaling carrying the MAC-I.

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: A path switching method includes: determining, by a base station, to switch a first terminal device from a first communication link to a second communication link, and sending, to the first terminal device by using a second terminal device, access information required by the first terminal device to access the base station, so that the first terminal device establishes the second communication link to the base station based on the access information. In the method, the second terminal device may release the first communication link before or after the second communication link is established, or may release the first communication link in a process of establishing the second communication link.

Abstract: In the embodiments of the present invention, a base station can determine a relay communication period of remote user equipment by using indication information carried in a resource request of relay user equipment or by using a resource request of the remote user equipment, and allocate a resource in the relay communication period to the relay user equipment, so that the relay user equipment returns a response message to the remote user equipment by using the resource. Therefore, for a request message sent by the remote user equipment, it can be ensured that the relay user equipment returns, in the relay communication period, a response message corresponding to the request message to the remote user equipment, to avoid a case in which the remote user equipment cannot detect the response message, and to reduce a failure probability of a service requested by the remote user equipment.
