Abstract:
Disclosed is a device-to-device (D2D) communications method and apparatus. A communications method performed in a second device comprises the steps of: receiving first configuration information for receiving a reference signal and second configuration information for reporting channel state information from a base station; receiving the reference signal based on the first configuration information from a first device; generating the channel state information on a communications link between the first device and the second device based on the reference signal; and transmitting the channel state information based on the second configuration information to the base station. Therefore, the D2D communications can be performed effectively.

Abstract:
Disclosed is a method for signaling control information for coordinated multipoint transmission in a wireless communication system. The method for signaling the control information performed in a base station for CoMP transmission supplies set information about each CSI-RS resource which belongs to a CoMP measurement set which is set in a terminal and selectively supplies the control information showing at least one information among quasi co-location information of CSI-RS and DM-RS and PDSCH resource element mapping information corresponding to the terminal to the terminal through DCI. Therefore, the control information for the CoMP is efficiently processed. [Reference numerals] (AA,DD) Frequency; (BB,EE) Time; (CC) Terminal
Abstract:
PURPOSE: A device-to-device (D2D) communication method in a wireless communication system is provided to control the transmission and reception of a sounding reference signal for measuring a channel state of a D2D link. CONSTITUTION: A first terminal (411) receives an activation reception allocation information of a first D2D link from a first base station (410) in a first sub frame (S410). The first terminal transmits whether a reception is successful about the activation reception allocation information of the first D2D link or not in a second sub frame after the fixed number of sub frames from the first sub frame (S430). The first terminal receives the data of the first D2D link from a second terminal based on the activation reception allocation information of the first D2D link in a third sub frame after the fixed number of sub frames from the second sub frame.

PURPOSE: A method of transmitting and receiving control information in a mobile communication system is provided to efficiently use resources by adaptively assigning the resources according to a required capacity of the control information. CONSTITUTION: Down link control information is generated. A down link control channel resource which transmits the down link control information is determined through a data channel domain. The generated down link control information is transmitted to a terminal using the determined control channel resource. The control channel is transmitted using either of a first slot(101) or a second slot(102) of a subframe(100) or both the first slot and the second slot.

The base station allocates respectively different virtual cell IDs in a downlink and an uplink.
Abstract:
PURPOSE: A wireless communication system using multiple transmission and reception points is provided to offer a physical channel transmission method and a reference signal transmission method for downlink communication using a plurality of transmission and reception points. CONSTITUTION: A wideband transmission and reception point(130) includes a wide transmission area(131) which is wider than one or more narrowband transmission and reception points(150). The wideband transmission and reception point and the one or more narrowband transmission and reception points creates a downlink transmission signal using physical cell ID(Identification). The wideband transmission and reception point uses high transmission power. The narrowband transmission and reception point uses power which is lower than the wideband transmission and reception band.
