20080198906APPARATUS AND METHOD FOR INCREASING CELL CAPACITY THROUGH OPTIONAL SIGNAL COMBINING BETWEEN RELAY STATIONS IN A CELLULAR SYSTEM USING WIRED RELAY STATIONS - A method, apparatus and system for increasing cell capacity through optional signal combining between Relay Stations (RSs) in a cellular system using wired RSs is disclosed. The method includes receiving, by a Base Station (BS), an average Carrier-to-Interference ratio (C/I) value of transmission signals from Mobile Stations (MSs) located inside each coverage area, being fed back from the RSs or the MSs in its corresponding cell; classifying the MSs into two groups according to the C/I value; performing resource allocation satisfying a minimum data rate from a corresponding RS, for MSs belonging to a group having a C/I value greater than a preset threshold Γ among the classified groups; performing resource allocation by applying an optional signal combining scheme taking into account two RSs having a highest C/I value, for MSs belonging to a group having a C/I value below the threshold among the classified groups; and allocating all unallocated subchannels of each individual RS in an order of an MS having a high C/I value among MSs of a corresponding RS until there is no more unallocated subchannel of each RS.08-21-2008
20090017835SIGNAL COMBINING APPARATUS SATISFYING MAXIMUM TRANSMISSION CAPACITY IN CELLULAR SYSTEM EMPLOYING DISTRIBUTED ANTENNAS AND RESOURCE ALLOCATION METHOD USING THE SAME - Disclosed is a signal combining apparatus and a resource allocation method using the same in a cellular system using distributed antennas. The resource allocation method includes detecting a channel transmission capacity when a signal is transmitted from a single Relay Station (RS) to a Mobile Station (MS), by a Base Station (BS), detecting a channel transmission capacity when transmitting a signal produced by using signal combining by two or more RSs to the MS, by the BS, selecting a channel transmission capacity with a larger gain between the detected channel transmission capacity of the single RS and the detected channel transmission capacity of the two or more RSs, by the BS; and selecting the signal transmitted by the single RS or the signal produced by using the signal combining by the two or more RSs having the selected channel transmission capacity with the larger gain, and then transmitting the selected signal to the MS.01-15-2009
