| 20100080269 | METHOD OF TRANSMITTING REFERENCE SIGNALS FOR COOPERATIVE WIRELESS COMMUNICATION SYSTEM AND METHOD OF ALLOCATING RADIO RESOURCES FOR RELAY-BASED WIRELESS COMMUNICATION SYSTEM - A method of transmitting reference signals in a wireless communication system for cooperative communication is provided. The wireless communication system defines a plurality of transmission patterns of the reference signals each having a different pattern, and each of a plurality of base stations and/or each of a base station and a relay station participating in the cooperative communication transmit the reference signals based on one transmission pattern selected from the plurality of transmission patterns of the reference signals. | 04-01-2010 |
| 20100142417 | RELAY STATION AND WIRELESS COMMUNICATION SYSTEM USING THE SAME - A relay station, method and system operated in a frequency division duplex (FDD) are disclosed. The relay station is operated in a band switching FDD mode and/or a dual band transmit (Tx)/receive (Rx) mode. In the band switching FDD mode, Tx frequency and Rx frequency are switched. In the dual band Tx/Rx mode, concurrent transmission or concurrent reception is achieved in the Tx frequency and Rx frequency. | 06-10-2010 |
| 20110044240 | Method for transmitting a packet at a base station in a network using multiple communication schemes - A method of transmitting a packet, at a MS and base station operable using multiple communication schemes is disclosed. The base station of the multiple communication schemes receives a packet from the MS and then determines a transmission path based on a link status of a network, a traffic characteristic of the packet and the like. The base station transmits the packet of the first communication scheme via a network using a second communication scheme, thereby enabling traffic redirection. Such a resource as a frequency band and the like, which will be used between networks using different communication schemes, can be cooperatively set between the MS and the base station. | 02-24-2011 |
| 20110058504 | SCHEDULING METHOD, MS APPARATUS USING THE SCHEDULING METHOD, DATA TRANSMISSION METHOD, AND BS APPARATUS USING THE DATA TRANSMISSION METHOD IN WIRELESS COMMUNICATION SYSTEM - In the MS apparatus for performing scheduling, a reception module receives any number information through a specific downlink channel in a first time unit from each of neighbor BSs. A scheduling module determines, among the neighbor BSs, a BS which is to transmit and receive data using a downlink data transmission region and an uplink data reception region, respectively, in a second time unit according to a previously set rule based on the number information. A transmission module transmits a signal, indicating that data transmission and reception using the downlink transmission region and uplink data reception region, respectively, in the second time unit are not possible, to the other neighbor BSs excluding the determined BS among the neighbor BSs. | 03-10-2011 |
