Abstract: An apparatus for setting the transmission power of a small-sized base station and a method therefor are provided to enable the small-sized base station to optimize the transmission power adaptively according to the state of an external base station. A small-sized base station operates in a terminal mode to scan neighboring base stations(201), measures the signal strength and thermal noise of the scanned neighboring base stations(203,205), and then selects the biggest value on the measured results(207) to set a target RSSI by adding a setup value to the selected result. The small-sized base station is converted into a general base station mode to communicate with terminals belonging to a coverage area(209), transmits a scan instruction message to the terminals within its coverage area(211), receives a scan report message including the scanning result from the terminals(213), and then selects the maximum value from the signal strengths of neighboring base stations which at least one terminal reports to set the selected maximum value as the maximum RSSI(215). Finally, the small-sized base station compares whether the maximum RSSI is identical to the target RSSI(217), if the RSSIs are different, determines whether the maximum RSSI is bigger than the target RSSI(219), and if so, reduces the transmission power by the set value(221).

Abstract: A scheduling method and apparatus in a communication system are provided to improve a resource usage rate and data transmission/reception rate by using more resources and scheduling band information of the optimum bands and band information of the others. A BS(Base Station) receives CQI(Channel Quality Indicator) including information about optimum bands, e.g., a band CINR(Carrier to Interference and Noise Ratio), from an MS(Mobile Station)(401). The BS updates a band CINR of physical bands through the CINR of the optimum bands(403). The BS estimates a band CINR of the other remaining bands than the optimum bands(405). The BS updates a band CINR of logical bands through the band CINR of the optimum bands included in the CQI and the band CINR of the bands estimated by using the band CINR of the optimum bands(407). The BS performs scheduling by using the band CINR of the logical bands and transmits/receives data to/from the MS(409).

Abstract: A power allocating apparatus and method of a space division multiple access system are provided to improve system performance by differentially distributing transmission power with respect to each terminal when a base station transmits a signal according to a channel state of each terminal. Terminals to be allocated radio resources at the same time period at the same frequency are determined(210). Transmission power of a base station is divided by the number of terminal to be allocated radio resources(220). A CINR(Carrier-to-Interference-and-Noise Ratio) of each terminal and each corresponding MPR(Modulation order Protection code Rate) value are obtained(230). Extra power of each terminal are added to obtain a total amount of extra power(240). Power required for each terminal to have an MPR of one-step higher(250). It is checked whether there exists a terminal for improving the MPR by checking whether there is a terminal whose power required for having an MPR of the next level is smaller than total extra power of the base station(260). When there is no such terminal, extra power is evenly distributed to each terminal(290).

Abstract: An apparatus for allocating radio resources in an adaptive antenna system and a method therefor are provided to estimate reception CINR(Carrier to Interference Noise Ratio) values of each terminal according to space division resource allocation and beam formation, and to allocate radio resources by compensating transmission power of each terminal, thereby preventing changes of a dynamic reception CINR. Physical radio resources are divided into a predetermined number of logical regional resources and a predetermined number of logical space resources for each logical regional resource(301,303). If empty logical resources or unallocated data sets exist, an unallocated logical regional resource having the highest receiving strength and a terminal having the highest priority are selected, and logical space resources necessary for allocating the selected terminal to the selected logical regional resource are calculated(305,307). If the number of the calculated logical space resources is smaller than or equal to empty space resources of the selected logical regional resource, the selected terminal is allocated to the selected logical regional resource, and the allocated terminal is removed from a scheduling set(309,313). If the empty resources or the unallocated data sets do not exist, the logical resource is allocated as a substantial physical wireless resource(315,317).
