Method, device and computer program product for wireless communication are provided. A method includes: transmitting, by a first wireless communication node, unmanned aerial vehicle, UAV, related information of a UAV to a second wireless communication node, wherein the UAV related information comprises at least one of UAV Flight Path Information or UAV Height Information.

Provided are a method and an apparatus for processing a Radio Link Failure (RLF) when duplicate data transmission is performed via single-BS-based CA. The method of processing an RLF by a user equipment (UE) may include: receiving, from a Base Station (BS), higher layer signaling including information for configuring duplicate data transmission via single BS-based CA; configuring a logical channel restricted to one or more secondary cells and a Radio Link Control (RLC) entity for duplicate transmission, based on the higher layer signaling; and transmitting, to the BS, a secondary cell failure report without performing RRC re-establishment procedure, when an RLF occurs in the RLC entity.

Provided is a method of modifying a data path between a user equipment (UE) and a core network node (CNN) in a wireless communication network. The method comprises the steps of: at a network node handling both signalling messages and user data for an existing data path between said UE and said CNN, obtaining data uniquely associated with a data path resource for said UE and/or uniquely identifying said UE and mapping said data to said existing data path; and modifying said existing data path based on said mapping. The network node handling both signal messaging and user data for an existing data path may comprise a gateway (GW) connecting a source base station (SBS) and a target base station (TBS) to a Mobility Management Entity (MME) of the core network, said GW being configured to handle both user plane data and control plane data for a plurality of UEs. The data uniquely associated with a data path resource for said UE and/or uniquely identifying said UE may be obtained from a Source to Target Transparent Container Information Element (IE) of a Handover Required message issued by the SBS.

An information interaction method, applicable to a first base station by which coverage of a cell is to be changed, the information interaction method includes: notifying by the first base station to a second base station that the coverage of the cell is to be changed by using a new information element different from ServedCellsToAdd, the new information element is used to indicate that the coverage of the cell is to be changed including that a cell is to be closed or a cell being to be shrunk in coverage.

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). A method for operating a proxy apparatus in a wireless communication system includes receiving a plurality of packets from a plurality of servers, and transmitting, to base station, data of one bearer data including the plurality of packets. A proxy apparatus in a wireless communication system includes a communication device configured to receive a plurality of packets from a plurality of servers, and transmit, to base station, data of one bearer including the plurality of packets. A base station apparatus in a wireless communication system includes a communication device configured to receive, from a proxy apparatus, data of one bearer including a plurality of packets.

A key management is provided that enables security activation before handing over a user equipment from a source 5G wireless communication system, i.e., a Next Generation System (NGS), to a target 4G wireless communication system, i.e., a Evolved Packet System (EPS)/Long Term Evolution (LTE). The key management achieves backward security, i.e., prevents the target 4G wireless communication system from getting knowledge of 5G security information used in the source 5G wireless communication system.

There is provided a method, apparatus, and computer program for causing a centralized unit of a second access point to perform: signalling, to a first distributed unit of a first access point configured to provide a serving cell to a user equipment, a plurality of power control parameters associated with a target cell and a reconfiguration instruction for configuring the user equipment to report uplink measurements with an indication of whether a maximum permissible exposure event has occurred.

Providing an indication whether a source radio network controller requests to receive system information from a handover target. Receiving the system information in a target to source transparent container, if the indication requests to receive the system information, and not receiving the system information in the target to source transparent container without the indication requesting to receive system information.

A method for processing information and a device for processing information are provided. The method for processing information is applied to a first node. The method includes: receiving, by the first node, an indication message from a network side, wherein the indication message indicates a user equipment under the first node to hand over to a second node; and negotiating, by the first node, with the second node to reserve radio link layer control protocol (RLC) status information and cached data of all bearers of the user equipment, so that the second node provides a continuing data service to the user equipment based on the reserved information.

A terminal device includes: a communication unit; and a control unit. The control unit transmits a measurement result relating to a radio wave environment and connection switching means information indicating which of two or more means of connection switching to another base station device is used to a first base station device through the communication unit, receives instruction information corresponding to the transmitted connection switching means information from the first base station device through the communication unit, and performs connection with a second base station device based on the instruction information.
