20090197624 | APPARATUS AND METHOD FOR RELAYING BETWEEN BASE STATION AND MOBILE STATION, AND METHOD FOR RECEIVING CONTROL INFORMATION - When an event associated with a mobile station occurs, a relay station requests a base station to allocate a dedicated control channel required for transmitting control information on the mobile station to the base station. Next, when the control information on the mobile station is generated, the relay station transmits the control information to the base station through the dedicated control channel. Accordingly, since the base station allocates the dedicated control channel to the relay station in advance before the control information is generated in the relay station, the relay station can transmit the control information to the base station with a minimum of time delay. | 08-06-2009 |
20100265936 | METHOD AND DEVICE FOR ACQUIRING SYNCHRONIZATION BETWEEN NODES AND METHOD FOR ORGANIZING MULTIPLE PHYSICAL CHANNELS - A method for acquiring synchronization between nodes and configuring multiple physical channels in order to improve performance in the ad-hoc/mesh network is disclosed. | 10-21-2010 |
20110149910 | METHOD FOR COMMUNICATION CHANNEL CONTROL - A base station designates an identification symbol section in each communication frame in order to identify a plurality of transceivers, transmits a predetermined transceiver identification signal through subcarriers granted to the plurality of transceivers by granting a combination of subcarriers to be used in an identification symbol section to each of the plurality of transceivers, generates and stores terminal connection information for each of the plurality of transceivers by receiving information on evaluation of reception quality for the transceiver from the terminal and using the received information, and allocates a communication resource so as to use the subcarrier of the transceiver connected with the terminal for communicating with the terminal. | 06-23-2011 |
20110206033 | COMMUNICATION METHOD BETWEEN WIRELESS NODES - In a wireless communication system, when a transmission node has data to be transmitted to a reception node, it checks an acknowledgement slot of the current communication frame and transmits information regarding a reception available acknowledgement slot to the reception node through a request-to-send (RTS) slot in the current communication frame, and the reception node transmits information regarding the data slot available for receiving among at least one data slot corresponding to the reception available acknowledgement slot to the transmission node through a clear-to-send (CTS) slot corresponding to the data request slot in the current communication frame. Thereafter, the transmission node transmits data to the reception node through a reservation data slot of the subsequent communication frame until the message transmission fails or finishes. | 08-25-2011 |
20120155370 | METHOD FOR SUPPORTING TIME SYNCHRONIZATION RELAYING TO NEIGHBORING NODES IN WIRELESS NETWORK - Under a wireless communication environment in which nodes sharing a time reference communicate information with a frame having a predetermined structure, when a node that has failed to acquire synchronization, a protocol in which neighboring nodes relays synchronization to the synchronization acquisition failed node by using a preamble defined in the frame is provided. | 06-21-2012 |
20120163257 | METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING IN MOBILE WIRELESS NETWORK - In a mobile wireless network system including a plurality of nodes communicating with each other, a node attempting to transmit data finds useable resources through performing carrier sensing on packet data unit (PDU) slots and transmits data through the found resources. A node attempting to receive data finds useable resource through performing carrier sensing on acknowledge (ACK) slots and receives data through the found resources. | 06-28-2012 |
20120163316 | METHOD AND APPARATUS FOR ALLOCATING RESOURCE IN MOBILE WIRELESS NETWORK - In a mobile wireless network system including a plurality of nodes, available resources of a transmitting node and available resources of a receiving node are searched for. Commonly overlapped allocatable resources among available resources of a transmitting node and available resources of a receiving node are searched for, areas corresponding to the calculated allocation resource number according to an allocation condition that is set in the allocatable resource area are selected, and the areas are allocated to the transmitting node or the receiving node. | 06-28-2012 |
20120188924 | METHOD FOR CONTROLLING POWER IN WIRELESS AD-HOC NETWORK - A node in a wireless network system determines transmission power by performing transmission power control only on a plurality of data subcarriers, other than a plurality of pilot subcarriers, of a PDU slot or ACK slot to be transmitted, and then transmits the data subcarriers of the PDU slot or ACK slot at the determined transmission power and transmits the pilot subcarriers of the PDU slot or ACK slot at a fixed power level. Accordingly, neighboring nodes determine whether or not a channel of the PDU slot or ACK slot is sensed by using the pilot subcarriers of the PDU slot or ACK slot. | 07-26-2012 |
20130250839 | METHOD AND DEVICE FOR ACQUIRING SYNCHRONIZATION BETWEEN NODES AND METHOD FOR ORGANIZING MULTIPLE PHYSICAL CHANNELS - A method for acquiring synchronization between nodes and configuring multiple physical channels in order to improve performance in the ad-hoc/mesh network is disclosed. | 09-26-2013 |
