  • Publication number: 20140341178
    Abstract: A communication method between a plurality of terminals and a resource allocation method in an infrastructure network are disclosed. A terminal according to an embodiment communicates with at least one other terminal using a particular frequency band in a third time section distinguished from a first time section for reception of a downlink data and a second time section for transmission of an uplink data, thereby providing a technology of generating a small-scale network partly with respect to a particular region in a network with an extensive coverage of an infrastructure network.
