Publication number: 20140241234Abstract: The present invention discloses a method for transmitting control information. Downlink control information is categorized into common control information and dedicated control information. A physical broadcast channel is extended by dividing a common control channel domain into a plurality of narrowband sub-control channel domains by adding a position identifier. Before a connection is established, the common control information is sent, according to the position identifier, in each sub-control channel domain of the common control channel domain. After the connection is established, a sub-control channel domain with a channel state that complies with a set standard is selected, according to a channel state of each sub-control channel domain, for sending the dedicated control information.Type: ApplicationFiled: May 7, 2014Publication date: August 28, 2014Inventors: Song Zhu, Yue Li, Bin Zhen

Patent number: 8351339Abstract: A method for Bluetooth on-demand routing, and network formation, and a communication method of a Bluetooth group ad hoc network. With respect to a Bluetooth network system that has a source node, a destination node and a plurality of independent nodes, the method includes the forward and the backward path set-up steps. In the forward path set-up step, the source node sends out a route request message, thus setting up multi forward paths towards the source node and the destination node. In the backward path set-up step, the destination node in receipt of the route request message sends out a route reply message to the source node through one of the set forward paths, thus setting up a backward path. Through the set backward path, a route is formed as the most suitable path between the source node and the destination node to save battery power and provide broader bandwidth.Type: GrantFiled: April 9, 2003Date of Patent: January 8, 2013Assignee: Samsung Electronics Co., Ltd.Inventors: Bin Zhen, Myung-jong Lee

Patent number: 8279111Abstract: A high-precision distance measuring with a reduced error in a distance measuring system which calculates a distance from an arrival time of each pulse signal constituting a pulse sequence is provided. For an oscillator which generates pulse signals by counting the number of pulse signals constituting a received pulse sequence, a relative time difference between a transmitting device and a return device is acquired, a distance from the transmitting device to the return device is calculated, and the calculated distance is corrected based on the calculated relative time difference.Type: GrantFiled: February 9, 2007Date of Patent: October 2, 2012Assignee: National Institute of Information and Communications TechnologyInventors: Bin Zhen, Huan-Bang Li, Ryuji Kohno

Publication number: 20110164605Abstract: A wireless communication system includes a coordinator (3) that broadcasts a beacon (21) having at least a preamble part (32) and a payload part (33), and a plurality of devices (2) each of which is synchronizable with at least the coordinator (3) by listening to the beacon (21) through a listen period set based on an own reference clock. The coordinator (3) fixes a position of the end of the beacon (21) with respect to a beacon slot constituting a superframe, and generates the beacon (21) where a start of a preamble part (32) is extended toward a start of the beacon slot over a time To. The devices (2) are synchronized with the coordinator (3) via an end time of the beacon slot detected from an end time of the preamble part (32) in the beacon frame.Type: ApplicationFiled: September 9, 2008Publication date: July 7, 2011Applicant: NATIONAL INSTITUTE OF INFORMATION AND COMMUNICATIONS TECHNOLOGYInventors: Bin Zhen, Huan-Bang Li, Ryuji Kohno

Patent number: 7372866Abstract: The present invention discloses an apparatus and method for avoiding mutual interference between wireless communication systems. A measurement unit measures the strength of a signal received through a channel to be used in a transmission slot for a switching time of a reception mode and a transmission mode. A judgment unit compares the strength of the received signal with the strength of a reference signal, and judges data transmission. A control unit outputs a signal for performing a transmission operation of the data according to the judgment of the judgment unit. The wireless communication system transmits the data according to the input signal from the control unit. The data transmission is decided by confirming the state of the transmission slot, thereby avoiding collision with a communication apparatus using a frequency identical to a frequency of the channel of the transmission slot.Type: GrantFiled: March 18, 2002Date of Patent: May 13, 2008Assignee: Samsung Electronics Co., Ltd.Inventors: Kyung-Hun Jang, Jong-hun Park, Bin Zhen
