Abstract: An access network device determines to add, for a remote terminal device, a direct path for connecting a first cell. The remote terminal device is connected to a second cell through an indirect path. The access network device sends an RRC reconfiguration message to indicate the remote terminal device to switch to the direct path. The RRC reconfiguration message further indicate not to release the indirect path. When being indicated to switch to the direct path, the remote terminal device may further be indicated not to release the indirect path.

Abstract: Example communication methods, apparatus, storage media are described. In one example method, a first node obtains a backhaul adaptation protocol (BAP) routing identifier of a data packet and a topology type indicator of a topology that the data packet needs to pass through. The first node determines a source internet protocol (IP) address based on the BAP routing identifier, the topology type indicator, and a correspondence between a topology type and an IP address.

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: A directional sound pickup method and a device implement targeted sound pickup for one or more targets without affecting video recording. An electronic device may identify a directional sound pickup target based on selection of a target object (or a region) in a viewfinder frame so that during audio recording, a sound signal from an identified target is picked up in a targeted manner, for example, a sound intensity of the directional sound pickup target is enhanced and/or a sound intensity of another target is weakened, or a sound intensity of another target is excluded.

Abstract: A method and apparatus for adaptively processing video samples in a video signal frame, the video samples being arranged in a Largest Coding Unit. The method comprises extracting a plurality of video samples from the Largest Coding Unit, calculating a correction offset for a first video sample of the extracted plurality of video samples upon the basis of a first value of the first video sample and a second value of a second video sample of the extracted plurality of video samples, and weighting the first video sample with the correction offset.

Abstract: The technology of this application is directed to reducing a data transmission latency in multi-hop transmission and improving data transmission efficiency, A method is provided and may be applied to a multi-hop transmission system. The method includes a first node obtaining second transmission parameter information. The second transmission parameter information may include one or more of the following: quality of service (QoS) configuration information, candidate transmission path information, candidate transmission resource information, or a candidate forwarding mode. The first node determines first transmission parameter information based on the second transmission parameter information. The first node sends service data to a second node based on the first transmission parameter information, where the second node is a next-hop node determined by the first node based on the first transmission parameter information.
