A terminal includes: a receiving unit of receiving first information for configuring scheduling and second information for executing scheduling from a base station; and a control unit that identifies a single scheduled carrier or a plurality of scheduled carriers, based on the first information and the single second information.

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.

A network operating system (NOS) acquires, for a plurality of network functions that achieve a network slice constructed on a mobile wireless communication network, information on an operation of each network function which is measured by one or more apparatus configured to provide at least a part of the plurality of network functions. The NOS derives an evaluation index value of each of the plurality of network functions based on the information on the operation of each of the plurality of network functions, and derives an evaluation index value of the network slice based on the evaluation index values of the plurality of network functions.
