According to one or more embodiments of the disclosure, a device receives data regarding wireless communications between a wireless access point and a client. The device evaluates, based on the data, motion of the client relative to the wireless access point. The device makes, based on the motion of the client relative to the wireless access point, a determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point. The device adjusts the wireless communications, based on the determination that the motion of the client relative to the wireless access point will result in the wireless communications degrading as the client approaches the wireless access point.

The present invention relates to a method and a device for selecting a cell in a mobile communication system and, more particularly, to a method and a device for selecting a cell for transmitting data, by a base station, not only in a licensed frequency band but in an unlicensed frequency band. In order to achieve the described task, a method for configuring a cell of a base station in a mobile communication system according to an embodiment of the present invention comprises the steps of: connecting with a terminal through a first cell of a licensed band; transmitting, to the terminal, a message for configuring multiple second cells in an unlicensed band through the first cell; and monitoring the configured multiple second cells in the unlicensed band, wherein the number of the multiple second cells exceeds the number of cells, a Carrier Aggregation (CA) of which the terminal can support. The present disclosure relates to a 5G or a pre-5G communication system to be provided in order to support a higher data transmission rate after a 4G communication system such as an LTE.

A communications method, device, and system for solving the connection and communications efficiency problem due to the presence of a large number of cells. The method comprises: a first local controller determines that a user equipment needs to establish a data bearer; data bearer configuration information for transmitting user data is generated; the data bearer configuration information is transmitted to a first local gateway and/or at least a first small base station, so that the network element entity that has received the data bearer configuration information establishes a data transmission channel according to the data bearer configuration information, the user equipment belonging to the first local controller and the first local gateway, the first small base station providing services to the user equipment.

[Object] To enable flexible arrangement of cells with a smaller burden. [Solution] Provided is an apparatus including: an acquisition unit configured to acquire information indicating one or more second base stations located within coverage of a first base station connected to a wired backhaul; and a controller configured to control establishment of a wireless backhaul between the first base station and each of the one or more second base stations.

A wireless communication system using cells to provide wireless access to services, comprising a first base station installed on board a public transportation vehicle to provide a moving cell, and a second base station installed at a stop at which users enter or leave the vehicle, to provide a fixed cell. A central controller guides handovers of users entering or leaving the vehicle. The first and second base stations to provide data concerning users to the central controller, and the central controller, over many journeys of the vehicle, gathers profile data of users based on the data provided by the base stations. As the vehicle approaches a stop, the central controller makes predictions about users likely to enter and leave the vehicle, and, provides guidance to the first and second base stations for performing handovers.

Disclosed are various embodiments for assigning a short address to a node in a network. A first node receives an association request that is a request from a second node to join the network. The first node transmits an association response to the second node, whereby the association response permits the second node to conditionally join the network and enter a low-power state. Data from the association request is transmitted to a coordinator node for the network on behalf of the second node. The first node receives a proxy response from the coordinator node in response to the data from the association request. When the second node is active, a notification is transmitted to the second node based on the response to the request. The notification includes an assignment of a short address when the response indicates the second node has joined the network.
