MULTIPLEXING AND CODING SCHEMES FOR MULTIPLE TRANSMIT ANTENNAS IN WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD).SOLUTION: For the SORTD scheme, a different orthogonal resource is assigned to each transmit antenna. Data is sent from the multiple transmit antennas using multiple orthogonal resources. UE processes at least one information bit with joint or independent coding to obtain first and second sets of at least one modulation symbol. The UE processes the first set of modulation symbols for transmission from the first transmit antenna using a first orthogonal resource. The UE processes the second set of modulation symbols for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource includes a different reference signal sequence or a different set of a reference signal sequence and an orthogonal sequence.
