Abstract:
The present invention relates to a Method for a device-to-device (D2D) communication in a wireless communication system. Specifically, when a terminal, which is performing a device-to-device communication while performing channel hopping, additionally performs the device-to-device communication with a new terminal, a channel hopping period of the existing device to device communication is configured by same time intervals for channels and one time interval among the same time intervals is configured to be identical to a channel hopping period for discovering a new terminal.
Abstract:
The D2D communication method may comprise the step of: transmitting, by a search device, a search request message through each of a plurality of channels in a search area, the search area corresponding to time resource allocated to integer multiple slots; receiving, by the search device, a search response message as a response to the search request message from a device found through at least one channel from among the plurality of channels in the search area, the search response message containing slot timing information and information on a first channel hopping pattern; synchronizing with the found device based on the slot timing information in a peering area by the search device; and performing communication with the found device, by the search device, on the basis of the information on the first channel hopping pattern in a communication area.
Abstract:
The present invention relates to a method for performing communication between terminals (D2D). Specifically, the method is characterized in that when a terminal communicating with another terminal is to perform an additional communication with yet another terminal, the channel sequence of the communicating terminal is determined, and one of the two terminals communicating with each other is defined as the channel synchronization reference terminal performing synchronization.
