Title: WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION DEVICE, AND COMMUNICATION METHOD
Abstract:
Proposed is a technology for improving throughput of inter-terminal data communication when the wireless environment between terminals is better than that between a base station and a terminal. According to the present invention, a base station acquires surrounding terminal information from terminal stations (#1), (#2) (S10), and, upon receipt of an inter-terminal communication request (S12), determines whether or not the condition for allowing inter-terminal direct communication is fulfilled (S14). In the case when the condition is fulfilled (Y at S14), the base station lets the communication between terminal (#1) and terminal (#2) be executed by inter-terminal direct communication without involving the base station itself (S18).
