摘要： A resource allocation scheduling method for a cellular communication system that can avoid interference between cells. The method includes dividing a frequency band of a system into frames each having preferential allocation blocks and general allocation blocks on a time axis, classifying terminals in each cell into groups of terminals vulnerable to interference and terminals non-vulnerable to interference, and allocating resources by terminal groups according to priority orders given to the terminal groups. The preferential allocation resources designed to have the orthogonality to the interference cells, i.e., sectors, on the time axis are allocated to the terminals vulnerable to the interference, and the remaining resources are allocated to the terminals non-vulnerable to the interference.

摘要： Provided is a multiple-input multiple-output (MIMO) data transmission method. A transmitter generates a transmission symbol by adding a parity symbol to a predetermined number of data symbols, generates a preprocessed symbol by multiplying the predetermined number of transmission symbols by a preprocessing matrix in units of blocks, selects a transmission antenna associated with a non-zero transmission symbol among preprocessed transmission symbols constituting the preprocessed symbol, and transmits the preprocessed symbol via the selected transmission antenna. A receiver receives a signal transmitted from the transmitter, estimates a preprocessed symbol and a transmission antenna index from the received signal, and restores the transmission symbols using the estimated preprocessed symbol and transmission antenna index.
