| 20090073952 | METHOD AND APPARATUS FOR RETRANSMITTING DATA IN WIRELESS LAN SYSTEM USING VISIBLE LIGHT COMMUNICATION - A method for retransmitting data when data transmission/reception has failed in a wireless LAN system using visible light communication. A mobile node searches a received frame for a fast feedback slot allocated for retransmission information when momentary data transmission/reception failure has occurred. One mini-slot from among the plurality of mini-slots is selected from the fast feedback slot. The mobile node transmits a fast feedback message, including information for retransmission, to an access point by using the selected mini-slot. | 03-19-2009 |

| 20080207214 | Apparatus and method for allocating uplink radio resource in wideband wireless communication system - An apparatus and method for UpLink (UL) radio resource allocation in a wideband wireless communication system are provided. In a method of operating a Relay Station (RS) for UpLink (UL) radio resource allocation in a wideband wireless communication system, the method includes relaying to a Base Station (BS) a resource request message of at least one or more Mobile Stations (MSs); receiving data from the at least one or more mobile stations; if the received data is non-real time traffic, queuing the data received from the mobile stations according to a traffic type; and requesting the base station to allocate necessary radio resources by checking a queue status. Accordingly, a delay can be reduced when the UL resource is allocated to an relay station for real time traffic. | 08-28-2008 |
