The present invention relates to a method for transmitting data by a base station in a wireless communication system supporting carrier aggregation, comprising the steps of: confirming whether a condition for data transmission distribution is satisfied; if the condition is satisfied, determining respective radio link control (RLC) data to be allocated to the base station and another base station, and sequence numbers for the RLC data; and transmitting the RLC data allocated to the other base station and the sequence numbers. However, the present invention is not limited to the embodiment above and other embodiments are possible.

Method and apparatus for transmitting data in wireless communication system supporting carrier aggregation

The present disclosure relates to a load balancing for a control in a wireless communication system. According to a various embodiments of the present disclosure, a method for operating a base station in a wireless communication system comprises determining a mobility of a terminal, and responsive to the mobility exceeding a threshold, transmitting, to the terminal, a message for requesting the terminal to process a control plane of the terminal with at least one other base station.

Apparatus and method for load balancing in wireless communication system

A method for setting a path by a base station in a mobile communication system and a system thereof are provided. The base station measures quality of a link directly connected to the mobile terminal using the received signal, if a signal is directly received from a mobile terminal. If the signal is received via at least one relaying node, the base station calculates quality of an entire path determined taking quality of each link into account, depending on the signal received via the at least one relaying node. The base station compares the calculated quality of the entire path with the quality of the directly connected link, and determines an optimal path according to the comparison result. The base station sends a relaying request message to a relaying node corresponding to the optimal path. Upon receipt of a relaying response message from the relaying node, the base station configures new broadcast information and broadcasts the newly configured broadcast information.

Relaying method of a mobile communication system and system thereof

A method and system for relaying data in a mobile communication system are provided, in which a Relay Station (RS) configures a routing table using Link Quality Information (LQI) exchanged among Relay Stations (RSs) in a cell, determines a relay path referring to the routing table, measures the quality of a signal received from an Mobile Station (MS), determines whether to relay data received from the MS by comparing the measured signal quality with at least one of information regarding a data rate of the MS and a reference threshold, transmits a relay request message to a Base Station (BS), if the RS determines to relay the data received from the MS, updates the relay path, upon receipt of a relay response message accepting the relay request and broadcasting information from the BS, and relays the data received from the MS to the BS in the updated relay path.
