Abstract:
An operation method of a transmitting apparatus in a multi-connection based mobile communication system includes generating combined data by combining data and an extended information element (IE), when the data received from a serving gate way (SGW) or a core network is determined to be transmitted to a receiving apparatus; transmitting the combined data to the receiving apparatus; and receiving, from the receiving apparatus, feedback information indicating whether or not the receiving apparatus normally receives the combined data.

An integrated base station which is a combination of a small cell base station and a wireless LAN access point is provided. The integrated base station includes: a small cell antenna that transmits and receives a small cell broadcast signal; a wireless LAN antenna that transmits and receives a wireless LAN signal; a small cell communication unit that broadcasts small cell broadcast information including wireless LAN access point information via the small cell antenna; and a wireless LAN communication unit that receives a wireless LAN report including a small cell camp-on report from a terminal that has received the small cell broadcast information, and passes the small cell camp-on report to the small cell communication unit.
Abstract:
The present invention relates to a method of selecting, by an eNB, a PCC for UE in a multiple component carrier system. The method includes obtaining mobility state information about the UE and coverage information and load information about carriers managed by the eNB; determining whether or not a mobility state value of the UE is greater than a specific threshold based on the obtained mobility state information; and selecting the PCC based on the load information if, as a result of the determination, the mobility state value is greater than the specific threshold. In accordance with the present invention, a BS adaptively selects a PCC by taking the load state of a carrier (or cell), UE mobility velocity, and the coverage of each carrier (or cell) into consideration.
Abstract:
The present invention relates to a method and apparatus for controlling traffic which can be applied to the next generation mobile communication system. The method includes determining whether or not a load state of a cell is greater than a threshold, determining whether or not UE capable of D2D communication is present in UEs connected to the cell if, as a result of the determination, it is determined that the load state is greater than the threshold, performing a D2D communication configuration on the UE capable of D2D communication, determining whether or not UE capable of handover is present in remaining UEs not capable of the D2D communication, and performing a handover communication configuration on the UE capable of handover. According to the present invention, a signaling overload due to the simultaneous handover of a plurality of UEs or congestion of traffic in a target cell can be prevented.
Abstract:
According to an exemplary embodiment of the present invention, a master base station selects a target serving cell in which a state is changed, among the serving cells of at least one slave base station set in the terminal, generates a MAC control element which instructs a state change of the target serving cell, and then directly transmits the MAC control element to the terminal in the case of an uplink asynchronous state between the target slave base station managing the target serving cell and the terminal.
Abstract:
An apparatus for allocating resources of a cell allocates some of the entire frequency band for a D2D link in the entire zone of the cell, allocates the rest of the entire frequency band for a cellular link in at least some zone of the cell, and allocates time resources different from those of D2D links of adjacent cells to the D2D link.
Abstract:
A carrier aggregation-based interference control method and apparatus for small base stations are disclosed. The present invention comprises setting a primary component carrier (PCC) as a first carrier and setting a secondary component carrier (SCC) as a second carrier, monitoring a signal-to-interference plus noise ratio (SINR) of the first carrier or the second carrier, and determining whether the SINR of the first carrier is smaller than a predetermined threshold.
Abstract:
The present invention relates to a method and apparatus for managing radio resources in a multi-carrier and heterogeneous network-integrated radio access environment. A method of managing radio resources in a BS supporting multiple carriers includes sending an RRC connection reconfiguration message, including measurement control information, to UE, receiving a measurement report, including a measurement result for an HetNet RAT cell, from the UE, determining to configure HetNet RAT bearer connection with the UE based on the measurement report, sending an RRC connection reconfiguration message, requesting to configure the HetNet RAT bearer connection, to the UE, and sending some of or the entire traffic for the UE, to the UE through the HetNet RAT bearer. If overload or interference occurs in a serving cell, some of or the entire traffic is transmitted through a cell based on HetNet RAT, if necessary. Accordingly, load balancing or interference coordination can be achieved.
