Abstract: An apparatus and a method for measuring an SINR(Signal-to-Interference and Noise Ratio) by using a preamble in a mobile communication system are provided to enable more precise estimation for the SINR although selective frequency fading is too much, by using the fact that density of the preamble is higher than a pilot. An SINR estimator calculates the average noise power by using the CP(Cyclic Prefix) of a received signal. On the assumption that an identical frequency domain channel exists between neighbor sub-carriers of an identical segment, the SINR estimator calculates the signal power of a serving segment(601), calculates average power of the serving segment, and then calculates interference power of the serving segment by using the difference between the sum of the average noise power and the signal power of the serving segment and the calculated average power. The SINR estimator calculates the average power of each interference segment, and obtains the interference power of each interference segment, based on the difference between the average noise power and the calculated average power(603). The SINR estimator divides the signal power of the serving segment by the sum of the average noise power and the total interference power and obtains the SINR of the received signal(605).

Abstract: A method and a system for transmitting data in a communication system are provided to enable MSs(Mobile Stations), which suffers cell interference from a neighbor cell, to easily remove the cell interference by segmenting a data transmission domain into an interference domain and a non-interference domain, and then transmitting data through either the interference domain or the non-interference domain according to feedback information received from each MS. An MS measures the CINR(Carrier to Interference Noise Ratio) or RSSI(Received Signal Strength Indicator) of a signal received from a serving BS(Base Station) and compares the measured value with a preset threshold(801,802). According to the comparison result, the MS creates an interference domain allocation flag and transmits the created flag information to the serving BS(805,807). Based on the flag information, the serving BS judges whether the MS exists in an interference domain or a non-interference domain(809). In case the MS exists in the interference domain, the serving BS allocates interference domain resources to the MS. Then, the serving BS inserts interference domain allocation information in the MAP message domain of a frame and transmits the frame to the MS(811,815).

The MIMO detection part(402) generates the soft decision values of coded bits using a list composed of an Rx vector, prior information from the decoder(408), and candidate code symbol vectors. The decoder(408) executes SISO(Soft-Input/Soft-Output) decoding for the soft decision values, generated from the MIMO detection part(402), using prior information and generates the soft decision values of coded bits. The hard decision part(413) carries out hard decision for the soft decision values outputted from the decoder(408) and generates code symbol vectors. The list updating part(401) creates a list of candidate code symbol vectors using the Rx vector at the first iteration and provides it to the MIMO detection part(402). At the next iterations, the list updating part(401) updates the list using the code symbol vectors outputted from the hard decision part(413) and provides the updated list to the MIMO detection part(402).
