Abstract: Methods, systems, and devices related to digital wireless communication, and more specifically, to techniques related to implementing SCG suspension. In one exemplary aspect, a method for wireless communication includes detecting data to be transmitted via a group of cells. The method also includes transmitting a first message initiating activation of the group of cells to a network node. In another exemplary aspect, a method for wireless communication includes receiving a first message providing an indication to activate a serving cell included in a group of cells from a network node. The method also includes activating the serving cell of the group of cells based on the first message.

Abstract: Provided are an address allocation method and apparatus, a core network, a node, a network system and a medium. In at least one of the case of establishing a session, at least two uplink addresses are configured and send to an access network. The access network is a connectivity network formed by a coupling of at least two network element nodes. At least part of the at least two uplink addresses are used for being allocated among the network element nodes. The access network receives the at least two uplink addresses sent by the core network and allocates the at least two uplink addresses. The access network sends at least one downlink address to the core network and determines usage of the uplink addresses. The access network may determine a correspondence between the uplink address and the downlink address. The core network receives the downlink address.

Abstract: Provided are a method and a device for determining a carrier for bearing a paging message and sending a paging message. The method for determining a carrier for bearing a paging message can comprise: acquiring, from a paging message sent by a mobility management entity (MME) or information locally stored by a base station, a paging characteristic of a terminal, where the paging characteristic indicates whether the terminal has the capability of supporting a non-anchor carrier for bearing the paging message; and determining a carrier for bearing the paging message corresponding to the terminal according to the paging characteristic.

Abstract: Provided is a dynamic scheduling method and apparatus. The method includes: in a process in which a user equipment (UE) receives data of a channel A, the UE triggers to start or restart an inactivity timer a preset length at a preset moment; during running of the inactivity timer, the UE receives a Physical Downlink Control Channel (PDCCH) signaling sent by a base station, and detects a PDCCH signaling for scheduling a downlink control information (DCI) of the channel A.
