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.
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a service discovery method and device in a wireless LAN system. A service discovery method in a wireless LAN system according to one embodiment of the present invention can comprise: transmitting, by a request device, a service discovery request frame to a response device; and receiving, by the request device, a service discovery response frame, which comprises service information of the response device and service information of each of one or more other devices, from the response device. The one or more other devices can comprise a device which does not belong to the same group as the response device.
