Abstract:
One embodiment of the present invention is a device-to-device (D2D) communication method. According to said method, a first terminal performs D2D communication with a second terminal in a wireless communication system, and comprises the steps of: receiving a first signal from the second terminal; and transmitting a second signal based on the received first signal to a third terminal. The first signal and the second signal are used in acquiring synchronization related to the D2D communication in each of the first terminal and the third terminal.
Abstract:
A method and mobile station are described for reporting channel quality information for multi-cell cooperation. The mobile station receives a channel quality request message for requesting channel quality information from a base station. The channel quality request message indicates that the mobile station is one of a plurality of candidate mobile stations to perform multi-cell cooperation. The mobile station reports the channel quality information to the base station. The channel quality information includes first channel quality information for the base station and second channel quality information for a neighboring base station.
Abstract:
Disclosed is a method for performing resource stream alignment (RSA) to be able communication through two data streams in a wireless communication system supporting multi cell, the method comprising: measuring wireless channel state between the first base station and the second base station receiving, by each base station, a channel status information related to a link of each mobile station from each mobile station, respectively; receiving, by the second base station, a channel status information related to a device-to-device (D2D) link from the second mobile station; exchanging channel status informationsreceived at each base station between the first base station and the second base station; and determining data stream directions of the first base station and the second base station based on the exchanged channel status informations.
