    • Disclosed is a method for transmitting MBSFN subframe configuration information of neighboring cells in a wireless system, the method comprises steps of: transmitting, by a base station of a serving cell, MBSFN subframe configuration information of the serving cell to a UE which accepts services from the serving cell via a broadcast control channel (BCCH); transmitting, by the base station of the serving cell, information on a subset relationship of MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell to the UE which accepts services from the serving cell via the broadcast control channel (BCCH); performing, by the UE, measurements on the neighboring cells according to the subframe configuration information of the serving cell and the information on the subset relationship of the MBSFN subframe configurations of the neighboring cells relative to the MBSFN subframe configuration of the serving cell. With the method of the present invention, the UE can learn about the MBSFN subframe configuration information of the neighboring cells in a more accurately manner. Therefore, more subframes can be measured to improve measurement precision. Meanwhile, the present invention is based on redefinition of messages in the existing method, and thus no extra signaling overhead will be introduced.

    • The present invention defines an efficient method for (re)selecting a cell according to a speed of a terminal in a HetNet where cells having various regions such as macro cells, pico cells and femto cells are arranged in the same frequency band in a mobile communication system. A cell selection control method of a terminal in a mobile communication system, according to an embodiment of the present invention, comprises a step of receiving, from a base station, cell list information for not allowing a terminal moving at a high speed to select a cell and a step of setting the terminal so that cells included in the cell list information are considered or not considered to be targets of selection or reselection when the terminal moves at the high speed. According to the present invention, in a network consisting of various types of cells using the same frequency band, the terminal can determine whether to select or reselect a cell according to the speed of the terminal. That is, the terminal moving at the high speed does not select or reselect a frequent service cell, thereby efficiently performing the cell selection or reselection. Further, power consumption of the terminal can be reduced.
    • 本发明定义了一种根据HetNet中的终端的速度(重新)选择小区的有效方法,其中具有诸如宏小区,微微小区和毫微微小区等各种区域的小区在移动通信中被布置在相同的频带中 系统。 根据本发明的实施例的移动通信系统中的终端的小区选择控制方法包括从基站接收小区列表信息,用于不允许终端高速移动以选择一个 小区和设置终端的步骤,使得当终端以高速移动时,包括在小区列表信息中的小区被认为是不被认为是选择或重选的目标。 根据本发明,在由使用相同频带的各种类型的小区组成的网络中,终端可以根据终端的速度来确定是选择还是重新选择小区。 也就是说,以高速移动的终端不选择或重新选择频繁的服务小区,从而有效地执行小区选择或重选。 此外,可以减少终端的功耗。

    • A method for transmitting data in a mobile communication system comprises the steps of: when not receiving a status report for a certain time after the initial transmission of a polling PDU, generating an RLC PDU that informs the retransmission of the initially transmitted polling PDU; and transmitting the RLC PDU that informs the retransmission of the generated polling PDU. The process of generating the RLC PDU that informs the retransmission of the polling PDU comprises the steps of: dividing the initially transmitted polling PDU into a certain number of segments to retransmit the segments of the polling PDU; setting up the payload size of a certain segment among those segments as 0; and setting up the segment whose payload size is 0 as the RLC PDU that informs the retransmission of the polling PDU, wherein the segment whose payload size is 0 may be the first or last segment among those segments.
