Abstract:
The present invention relates to a method for controlling resource allocation and a transmission rate based on a multi-hop ship communication network and, more specifically, to a method for controlling the transmission rate and for setting the size of a sub-frame based on the transmission rate of ships or the distribution of the ships existing in each hop area in the multi-hop ship communication network. Specifically, the present invention has effects for remarkably improving the performance of the whole system by enabling a ground base station to set the size of the sub-frame for the ships of each hop area and the ships existing in each hop area to determine overload and control the transmission rate and for rapidly and safely transmitting data by effectively distributing resources in the multi-hop ship communication network. Therefore, the reliability and competitiveness can be improved in a multi-hop communication field and a marine ship communication field. The present invention can also provide similar effects in various communication fields based on the technology. [Reference numerals] (S100) Required resource estimation step for estimating the sum of transmission rates or numbers of ships existing in each hop area; (S200) Sub-frame setting step for setting a sub-frame for controlling the size of a sub-frame divided by hop area based on the estimated result; (S300) Transmission rate control step for controlling the transmission rate of the sub-frame according to data transmission of the ships existing in each hop area
Abstract:
PURPOSE: A wireless communication terminal and a wireless communication method thereof are provided to increase frequency deny ratio and deny communication information which is received through different beam direction while performing communication. CONSTITUTION: A wireless communication device receives communication information through an antenna(S110). First to m beam forming units generate beam directions(S120). A beam direction selecting unit selects a beam direction(S130). The wireless communication device performs communication(S140). The wireless communication device enters a communication standby state(S150).
