Disclosed is a method for channel switching in a wireless mesh network. The method comprises: any slave node in a wireless mesh network receiving a channel switching command broadcast by a master node to perform channel switching; the slave node determining whether the channel switching is successful; and if successful, searching for the master node or a mesh network containing the master node for networking; otherwise, exiting the current invalid mesh network, and scanning for a mesh network after the channel switching, and joining the detected mesh network. According to the present application, after channel switching is performed, a mesh network for a slave node is automatically configured, thereby making up for the defect of an existing mesh network protocol not supporting switching between different frequency bands, and realizing automatic re-establishment of a mesh connection after the channel switching is successful.

Embodiments of the present application are directed to a method and apparatus for reporting time information of conditional handover (CHO). In an embodiment of the present application, the method includes: receiving configuration information on CHO, and transmitting time information of CHO in response to at least one failure that occurs during a CHO procedure.

The method includes: in a case that a sidelink is transmitted based on N carriers, determining, according to first entities associated with some or all of the N carriers, whether the sidelink satisfies a carrier failure condition, or determining, according to a first entity associated with each of the N carriers, whether the corresponding carrier satisfies a carrier reselection condition. N is an integer greater than 1, and the first entity includes at least one of a hybrid automatic repeat request (HARQ) entity and a radio link control (RLC) entity.

The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus for handling sidelink communication according to type of handover are provided.

An information processing apparatus that communicates with a communication apparatus includes a connecting unit that connects to a first access point in the communication apparatus, a connection-information acquisition unit that acquires connection information for connecting to a second access point in the communication apparatus via the first access point, a storage unit that stores the acquired connection information in a memory, and a receiving unit that receives an instruction to transmit data. Upon receipt of an instruction to transmit data when the connecting unit is not connected to the second access point, the connecting unit connects to the second access point using the stored connection information stored in the storage unit, and when the connecting unit is connected to the second access point, the first access point is disabled.

The disclosure provides a method for resource selection and a first device. The method is applied to a first device and includes the following. A first signaling is transmitted to a second device, where the first signaling is used to trigger the second device to transmit a resource set to the first device, and the resource set is used to assist the first device in sidelink (SL) transmission resource selection. The resource set is received from the second device. A resource for SL transmission is selected according to the resource set.

A device and a method for automatically deploying a communication network between a moving vehicle VM and a rear base BA, the moving vehicle moving from an initial position along a trajectory T. The deployment involves positioning a plurality of communication relay appliances along the trajectory of the VM to form, between the VM and the rear base, a two-way, linear wireless mesh communication network, such that the communications between the moving vehicle and the rear base maintain a communication link quality Q that is equal to or greater than a threshold value S. Each communication relay appliance is an autonomous mobile appliance, called Autonomous Robotic Communication Relay RCRA, capable of autonomously moving and of being positioned along the trajectory T followed by the VM in order to allow the quality of the communication link to be maintained.

An electronic device includes a traffic redirect module that creates a traffic sink interface that enables data to be sent to it, without generating an error if an underlying physical link does not exist. To send data over a physical link, a processor of the electronic device creates a network interface to connect to another electronic device using a transport connection over the physical link. If the physical link disconnects, then the processor removes the network interface, and the traffic redirect module redirects data to be sent to the other electronic device to use the traffic sink interface, without indicating that the physical link has disconnected. When the physical link reconnects, or a new physical link to the other electronic device is established, the processor creates a new network interface to connect to the other electronic device using the transport connection over the reconnected or new physical link.

The present specification relates to a device and method for wirelessly transmitting power on the basis of the reestablishment of out-band communication. The present specification discloses a wireless power receiving device comprising a communication/control circuit configured to carry out the operations of: performing handover from in-band communication using operating frequencies to out-band communication using any frequencies except for the operating frequencies; transmitting power characteristic information to the wireless power transmitting device or receiving power characteristic information from the wireless power transmitting device through the out-band communication before entering a power transmission phase; and saving power state information determined during the power transmission phase. By defining an out-band communication reestablishment protocol for the wireless power transmitting device or wireless power receiving device, it is possible to improve the performance of wireless power transmission throughout-band communication reestablishment that is fast and efficient.
