Abstract:
According to one embodiment of the present invention, disclosed is a method for a first pico base station for controlling handover between the first pico base station and a second pico base station in a wireless communication system. The method comprises the steps of: receiving, from user equipment, measurement results of a downlink reference signal of the second pico base station; and determining whether it is necessary to hand over to the second pico station based on the measurement results. If it is determined that it is necessary to handover to the second pico base station, the method may further comprise the steps of: sending an action switch request to the second pico base station; receiving setting data of the second pico base station for the action switch with the second pico base station; and changing the setting data of the first pico base station into the received setting data of the second pico base station.
Abstract:
A method and apparatus for controlling interference in a wireless communication system are disclosed. A method for measuring inter-cell interference by a pico eNB in a wireless communication system includes: receiving transmission information of a dummy signal to be transmitted on at least one candidate carrier from a neighbor pico eNB; scheduling at least one user equipment (UE) served by the pico eNB to measure the dummy signal based on the transmission information; receiving a measurement value of the dummy signal from the at least one UE; and transmitting a measurement report of the dummy signal based on the measurement value to the neighbor pico eNB, wherein the dummy signal transmission information is specified for each of a plurality of subframe sets of the at least one candidate carrier.
Abstract:
The present invention relates to a method for offloading data in a wireless communication system for supporting a multiple radio access network and an apparatus for same. Specifically, the method includes the steps of: receiving a message of a connected cell report including an identifier of a wireless local area network (WLAN) access point (AP) to which a terminal is connected via a base station, from the terminal connected to the base station of a cellular network; transmitting scheduling information on a data transmission time to the base station, when data to be transmitted to the terminal is determined to be transmitted via the WLAN AP; and transmitting the data via the WLAN AP to the terminal according to the scheduling information.
Abstract:
A method and apparatus for measuring inter-cell measurement in a wireless communication system are discussed. The method includes: receiving information regarding a predetermined resource region to which a sounding signal allocated for user equipments (UEs) connected to base stations (BSs) contained in the same coordinated cluster is transmitted, the sounding signal being used to detect a UE causing inter-cell interference; determining whether transmission of the sounding signal is granted for a serving UE in the predetermined resource region; and if transmission of the sounding signal is granted, transmitting a transmission grant message of the sounding signal to the serving UE, wherein whether the sounding signal transmission is granted is determined based on a random number, or is determined based on information of an available resource region of each BS if information regarding the available resource region of each BS is received with the information regarding the predetermined resource region.
Abstract:
According to one embodiment of the present invention, a method configured to enable user equipment to transmit or receive data relating to hybrid automatic repeat request (HARQ) process to/from a plurality of base stations in a wireless communication system may comprise the steps of: receiving, from a serving base station, information relating to HARQ processes allocated for the HARQ process of the plurality of base stations, and base station pattern information indicating the base station to/from which the user equipment transmits or receives the data in a specific subframe; and transmitting or receiving the data to/from at least one base station from among the plurality of base stations on the basis of the information relating to the HARQ processes and the base station pattern information.
