    Abstract: A method for wireless communication method by a user equipment (UE). The method involves multiplying a plurality of data symbols with a first scrambling sequence and a first orthogonal sequence, mapping the data symbols multiplied by the first scrambling sequence and the first orthogonal sequence to a first slot, multiplying a plurality of data symbols with a second scrambling sequence and a second orthogonal sequence and mapping the data symbols multiplied by the second scrambling sequence and the second orthogonal sequence to a second slot. The method further involves transmitting the first slot and the second slot to a base station. The first slot includes five DFT-S-OFDM symbols to transmit the data symbols and the second slot includes four DFT-S-OFDM symbols to transmit the data symbols. The first orthogonal sequence is selected from first predefined sequences and the second orthogonal sequence is selected from second predefined sequences. The sequence index of the first orthogonal sequence is the same as the sequence index of the second orthogonal sequence .

    Abstract: A method and a system for operating cooperative-receiving diversity, and a method and a system for selective and cooperative communication are provided to adopt a selective standard by considering the efficiencies of both a performance improvement effect and a radio resource allocation. An MS(Mobile Station) and an RS(Relay Station) measure the channel quality(S810), and reports the channel quality measurement information to a BS(Base Station)(S820). The BS determines whether or not the MS is a terminal for direct transmission or cooperative relaying(S830). If the MS is for cooperative relaying, the base station calculates an equivalent burst transmission rate(S840). The BS selects one of cooperative communication methods(S850).
