Abstract: A method for transmitting a sounding reference signal from a user equipment in a MIMO antenna wireless communication system. The method includes receiving sounding reference signal setup information from a base station, the sounding reference signal setup information including an initial cyclic shift value nSRScs and an initial transmissionComb parameter value kTC; setting an interval between cyclic shift values corresponding to each antenna port based on the initial cyclic shift value, to reach a maximum interval; setting a transmissionComb parameter value corresponding to a specific one of the antenna ports to a value different from the initial transmissionComb parameter value if the initial cyclic shift value is a previously set value and the number of antenna ports is 4; and transmitting the sounding reference signal to the base station through each antenna port by using the set cyclic shift value and transmissionComb parameter value.

Abstract: A method of performing paging by a first D2D terminal in a wireless communication system supporting D2D communication includes: obtaining information on a paging slot, the paging slot being designated to be dedicated to the first D2D terminal for the D2D communication and including a plurality of paging sections; monitoring whether a signal for the first D2D terminal is transmitted in a first paging section in the obtained paging slot through a region assigned to the first D2D terminal; monitoring whether a paging request message is transmitted in a paging region only for the first D2D terminal in a second paging section if the signal is detected; and transmitting a paging response message through a third paging section to the second D2D terminal that transmits the paging request signal, as a response to the paging request message, if the paging request message is detected.

Abstract: A method and apparatus for reconfiguring device-to-device (D2D) connection information in a wireless communication system is provided. A first device is connected to a second device through a D2D connection. The first device receives a connection reconfiguration request message including at least one of a new quality of service (QoS) parameter, a new security information parameter, and a new D2D identifier, transmits a connection reconfiguration response message, which indicates whether to accept the request of the connection reconfiguration, to the response of the connection reconfiguration request message, and receives a connection reconfiguration confirm message.

Abstract: The present invention relates to a wireless communication system, and more specifically, to a method and apparatus for reporting channel state information. A method in which a terminal transmits uplink control information (UCI) in a wireless communication system according to one embodiment of the present invention comprises: a step of determining channel state information (CSI) report timing; a step of determining acknowledgement/non-acknowledgement (ACK/NACK) information transmission timing; and a step of transmitting one or more pieces of the CSI or the ACK/NACK information via an uplink subframe. In the event that the CSI is invalid CSI, then said CSI is omitted, and only said ACK/NACK information can be transmitted via the uplink subframe.
