    Abstract: In wireless communication, a device may handover between cells of network access for inter-cell mobility without interruptions. In a Dual Active Protocol Stack (DAPS) handover, the user equipment (UE) maintains simultaneous connection with the source node and target node until releasing the source cell after successful access to the target cell. The source node may generate the power coordination and/or resource coordination parameters or configurations that are transmitted to the target node during the handover. When there is a centralized unit (CU) split from a distributed unit (DU), the CU or DU may generate and/or transmit the parameters/configurations to the peer node.

    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: Methods, apparatus and systems for scheduling and transmission of system information in a wireless communication are disclosed. In one embodiment, a method performed by a wireless communication node is disclosed. The method comprises: transmitting, to a first wireless communication device having a first device type, a first configuration associated with the first device type for the first wireless communication device to perform paging occasion monitoring, wherein a device having the first device type is a reduced capability device or is configured with extended discontinuous reception (eDRX); and transmitting, to a second wireless communication device having a second device type, a second configuration associated with the second device type for the second wireless communication device to perform paging occasion monitoring, wherein a device having the second device type is not a reduced capability device and not configured with eDRX.

    Abstract: The present disclosure discloses a method and apparatus for processing information. The method for processing information comprises: retrieving, by a first base station, user context information of a User Equipment (UE) from a second base station by initiating a procedure to the second base station for retrieving the user context information, wherein the user context information doesn't include user history information; updating, by the first base station, bearer path information and resuming the user context information by initiating a path switch request message to a device in a core network; and performing, by the first base station, one or more of the following operations after the UE resumes to a connected state: re-starting to collect user history information, and re-retrieving user history information from the UE through an air interface.

    Abstract: Described are a method, a device and a system for resuming a User Equipment (UE) context. The method includes: receiving, by a Mobility Management Entity (MME), a UE context resume request message sent by a base station; resuming, by the MME, the UE context corresponding to the UE context resume request message; under a condition that a UE context resuming fails, informing, by the MME, the base station of a failure of the UE context resuming. According to the embodiment of the present disclosure, the problem that the base station cannot know the failure of the UE context resuming can be solved, and an effect that the base station can know the failure of the UE context resuming can be achieved.
