Abstract: PURPOSE: An SoQ(Service of Quality) based cooperative communication protocol implementation method is provided to connect an installed system by having compatibility with a WiMedia D-MAC(Distributed-Medium Access Control) standard technology without modifying a specific system. CONSTITUTION: In case it is possible to reserve MAS S-R and MAS R-T for random relay nodes, a reservation host node sets up a reservation reason code of a DRP IE for MAS S-T as relay approval and transmits the reservation reason code to a reservation target node. The reservation host node sets up a reservation detail state code of the DRP IE for MAS S-R as relay request and transmits the reservation detail state code to the relay node. The relay node sets up the reservation detail state code of the DRP IE for MAS R-T as relay notification and transmits the reservation detail code to the reservation target node. In case the reservation detail code of the DRP IE received from the relay node and the reservation target node is relay approval, the reservation host node transmits data through the relay node.

Abstract: PURPOSE: A cell management method and a handover method are provided to increase the accuracy of handover generated in a boundary area of a cell by reducing the size of a cell management message including the information of a neighboring base station. CONSTITUTION: A serving base station broadcasts a neighboring base station notification message to a terminal. The neighboring base station notification message includes the information of a sector, in which a terminal is located, and the information of a base station which locates in a boundary area of a cell. A neighboring base station provides cell tier information to the terminal. When a reception signal of the serving base station is maintained during timeout time set as a predetermined value, the terminal handovers data to an adjacent cell. The predetermined value is smaller than a value except for a variable hysteresis margin of handover set from the reception signal of the neighboring base station.
