摘要： An apparatus includes one or more processors and a memory having instructions stored thereon that, when executed by the one or more processors, cause the apparatus to receive a first wake-up signal. The first wake-up signal is one of K wake-up signals, K is an integer greater than or equal to 1, and the K wake-up signals are quasi co-located with K synchronization signal blocks (SSBs), K channel state information-reference signals (CSI-RSs), or K demodulation reference signals (DMRSs). The apparatus is also caused to determine M paging occasions. There is a correspondence between the K wake-up signals and the M paging occasions, and M is an integer greater than or equal to 1. The apparatus is further caused to receive, on the M paging occasions, downlink control information (DCI) used for paging.

摘要： This application discloses a route selection method and a related device. A control entity determines first metric information of a first segment routing (SR) path, generates a first border gateway protocol (BGP) update message including the first metric information, and sends the first BGP update message to an ingress node of the first SR path, where the first metric information represents quality of the first SR path, the first metric information is used for route selection on a plurality of paths, each of the plurality of paths has a same IP prefix of a destination node, and the plurality of paths include the first SR path. According to the method, the control entity can send, to the ingress node of the SR path by using the BGP update message, the metric information that represents the quality of the SR path.
