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.

摘要： Provided is a handover method of a wireless communication system using a hierarchical cellular scheme. In the method, signal quality of a serving node is measured, so that whether to start scanning for a handover is determined. When the scanning for the handover starts, signal qualities of a serving cell including the serving node and one or more neighbor cells are measured through a first preamble including a first identifier for distinguishing a cell. An intra-cell handover or an inter-cell handover is selected using the signal qualities of the serving cell and the neighbor cells. Therefore, a terminal can easily distinguish between the inter-cell handover and the intra-cell handover, and an overhead during a handover can be reduced because an intra-cell handover procedure is simplified.
