Abstract: A method of allowing a local Driving Assistance Service (DAS) center within a base station to provide a DAS to a vehicle by using a communication network is provided. The method includes receiving, from a vehicle terminal, local DAS information and surrounding information of the vehicle, generating Analyzed-local (A-local) DAS information by using the received local DAS information, and transmitting, when the DAS is provided by using the generated A-local DAS information, the A-local DAS information to the vehicle terminal.

Abstract: Methods and apparatuses are provided for performing carrier aggregation (CA) using a plurality of almost blank subframe (ABS) patterns in a macro enhanced Node B (eNB) of a wireless communication system connected to a heterogeneous network. An ABS pattern having a different pattern is determined for each component carrier (CC), when two or more carriers are deployed in each of the macro eNB and at least one small cell eNB. A serving cell for each user equipment (UE) is determined for each CC, from among a macro cell and a small cell. CA is performed for data transmission to each UE using the determined ABS pattern, in accordance with each determined serving cell.

Abstract: A method and an apparatus for controlling an adaptive flow in a wireless communication system is provided. A method of a master base station in a wireless communication system, in which base stations having different cell sizes coexist, comprises the steps of: receiving load information from at least one other base station, receiving channel information about the at least one other base station from a terminal connected to the master base station, determining a secondary base station capable of load sharing for the terminal on basis of the channel information and the load information, and requesting, from the terminal, a further connection to the secondary base station. Offloading for downlink transmission of the terminal is determined based on the load information of a small cell. Furthermore, a resource distribution ratio for downlink transmission of the terminal is determined based on channel quality information reported from the terminal.

Abstract: An apparatus for a terminal in a wireless communication system includes a receiver configured to receive frame configuration information used by a second carrier which is operated using a Time Division Duplex (TDD) scheme and receive downlink data through downlink TDD-Frequency Division Duplex (FDD) Carrier Aggregation (CA) using a first carrier and the second carrier operated using an FDD scheme and a transmitter configured to transmit uplink data via the first carrier. The downlink data received via the second carrier is received through a downlink subframe identified by the frame configuration information.

Abstract: Performing scheduling operations by a centralized scheduler in a wireless communication system. Receiving Channel State Information (CSI) about a channel between each of a plurality of Transmission Points (TPs) and each of a plurality of User Equipments (UEs) performing communication with each of the plurality of TPs from each of the plurality of TPs, performing a first scheduling operation for allocating wireless resources to each of the plurality of TPs based on the CSI received from each of the plurality of TPs, and transmitting first scheduling information representing a result of the first scheduling operation to each of the plurality of TPs. The first scheduling information contains transmission power information representing transmission power for each of the wireless resources allocated to each of the plurality of TPs, and is used to perform a second scheduling operation to select a UE to communicate with each of the plurality of TPs.
