Abstract: A method for communicating between first multiple nodes and second multiple nodes in a wireless communication system is disclosed. The second multiple nodes may perform a first local sharing procedure for a virtual MIMO (Multiple Input Multiple Output) feedback during a first predetermined time. And then, the second multiple nodes may transmit feedback of channel status information to the first multiple nodes during an integer multiple of a second predetermined time. Finally, the first multiple nodes may perform a second local sharing procedure for the virtual MIMO feedback during the first predetermined time.

Abstract: Provided is an apparatus and method for transmitting and receiving a streaming service. An inter-arrival jitter may correspond to a delay variation in arrival time between TCP packets arriving at an apparatus for receiving the streaming service. The apparatus for receiving the streaming service may determine a de-jitter buffering time to absorb a network jitter before TS packets in a TCP packet is input to a T-STD buffer model. Based on the de-jitter buffering time, an initial playout delay lime at the apparatus for receiving the streaming service may be determined.

Abstract: A replay station and a method of operating the relay station in a multi-hop communication system are provided. A method of operating a relay station of a multi-hop communication system includes monitoring a delay of the relay station, determining whether the monitored delay exceeds a predetermined threshold, and controlling the relay station to be handed over to another upper relay station that is different from a connecting upper relay station.

Abstract: Disclosed herein is a method of analyzing load-settlement characteristics of a top-base foundation. The method includes the step of inputting properties of a material of a top base, a basic size of footing configuration, and a load of a structure, the step of inputting the kind of ground and a base ground thickness, the step of determining an influential depth and a load dispersion angle depending on the kind of ground, the step of inputting properties of the ground, the step of determining an immediate settlement amount of the ground, and the step of determining a total settlement amount. The method according to the present invention can precisely determine settlement taking into account footing configuration. Furthermore, the method calculates the settlement taking into account consolidation settlement when the ground is cohesive soil ground or top-cohesive-soil and bottom-sandy-soil ground. Thus, the settlement can be precisely determined.
