The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method and a device for configuring data transmission are provided. The method includes transmitting a first message to a second node, the first message being used for the first node to provide configuration information for a user to the second node, or used for the first node to request the configuration information for the user from the second node, and/or receiving a second message from the second node, the second message being used for the second node to provide the configuration information for the user to the first node, or used for the second node to request the configuration information for the user from the first node, to avoid unnecessary signaling overhead.

A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.

Methods, systems, and devices for wireless communications are described. The method includes receiving, from a first base station, control signaling indicating one or more frequency bands on which one or more neighbor base stations operate that are associated with a first geographic location of the first base station, performing, based on the control signaling, a frequency scanning procedure using at least one frequency band of the one or more frequency bands to select a first neighbor base station of the one or more neighbor base stations, and establishing connectivity with the first neighbor base station based on the frequency scanning procedure.

The present application relates to devices and components including apparatus, systems, and methods to provide positional information for one or more NTN devices to a UE to be utilized for one or more UE operations.

A mobile wireless communication device provides information to a communication infrastructure. In response to the information, a serving base station of the mobile wireless communication device sends a transition instruction to the mobile wireless communication device indicating the mobile wireless communication device is authorized to perform a transition procedure from the serving base station to any one of a group of base stations. The transition instruction authorizes the mobile wireless communication device to perform the transition procedure in response to a trigger and without transmitting any measurement reports. In response to determining the trigger has occurred and without transmitting a measurement report, the mobile wireless communication device transitions from receiving communication service from the serving base station to receiving communication service from a target base station of the group of base stations.

Aspects described herein relate to receiving, from a serving cell, a configuration for performing conditional handover to one or more target cells, establishing, based on detecting a condition from the configuration, a connection with a target cell for performing handover to the target cell, and transmitting, based on establishing the connection with the target cell and based on determining that the conditional handover is of a type where a source connection with the source cell remains, a notification to the serving cell.

A UE is configured to perform Radio Link Monitoring (RLM) with a first Coverage Enhancement (CE) configuration that provides a first CE level. The first RLM configuration associated with the first CE configuration has a first radio-link-quality-improving threshold value that corresponds with a third distance from a base station that is closer to the base station than a second distance associated with an in-sync radio link quality threshold value associated with a first RLM configuration. The first RLM configuration also has a first radio-link-quality-improving-cancellation threshold value that corresponds with a fourth distance from the base station that is located farther from the base station than the third distance and closer to the base station than the first distance. If conditions are satisfied, the base station reconfigures the UE with a second RLM configuration and a second CE configuration having a second CE level lower than the first CE level.

A network controller monitors a wireless access node for a fault. The wireless access node experiences the fault and scans for wireless Integrated Access and Backhaul (IAB) service. The network controller detects the fault and directs a neighbor access node to deliver the wireless IAB service. The neighbor access node delivers the wireless IAB service in response to the network controller. The wireless access node detects the wireless IAB service from the neighbor access node and exchanges fault data with the network controller using the wireless IAB service delivered by the neighbor access node. The network controller exchanges the fault data with the wireless access node using the wireless IAB service delivered by the neighbor access node. An Access and Mobility Management Function (AMF) or a User Plane Function (UPF) may detect a lack of signaling or data from the wireless access node to detect the fault.

A communication apparatus is provided that establishes a wireless LAN communication by handover. The communication apparatus communicates with an external apparatus through a first communication path. The communication apparatus includes a storage unit that store a communication parameter used for communicating with the external apparatus through a second communication path, a communication establishment control unit that performs control to establish communication with the external apparatus through the second communication path using the communication parameter stored, and a communication parameter change control unit that performs control to change the communication parameter stored in the external apparatus that establishes communication through the second communication path. The communication parameter change control unit prohibits change of the communication parameter stored in the external apparatus that establishes communication through the second communication path when the communication through the second communication path is established by switching from communication through the first communication path.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention provides a method for controlling Wireless Local Area Network (WLAN) aggregation and an associated equipment. The method comprises the following steps of: acquiring, by a first radio access network node, WLAN information about a User Equipment (UE); and, controlling, by the first radio access network node, WLAN aggregation for the UE according to the acquired WLAN information. A second radio access network node decides whether to maintain a WT and/or whether to establish WLAN aggregation for the UE when the UE moves to a first radio access network; and, the second radio access network node transmits information about whether to maintain the WT and/or indication information about whether to establish the WLAN aggregation for the UE. The WT receives UE context reference information transmitted by the first radio access network node; and, the WT indexes a UE context according to the received UE context reference information. With the present invention, the WLAN aggregation performance in a UE mobility scenario can be improved.
