    摘要: A transmitter is for use with multiple transmit antennas and includes a precoder unit configured to precode data for a transmission using a precoding matrix selected from a codebook, wherein the codebook corresponds to the following three transmission properties for an uplink transmission: 1) all precoding elements from the precoding matrix have a same magnitude, 2) each precoding element from the precoding matrix is taken from a set of finite values and 3) there is only one non-zero element in any row of the precoding matrix. The transmitter also includes a transmit unit configured to transmit the precoded data.

    摘要: A method for setting a periodicity and an offset in rank indicator (RI) reporting in a user equipment in a wireless communication system receives a radio resource control (RRC) signal from a base station, decodes a RI periodicity and offset configuration index, sets the periodicity and offset in accordance with said decoded periodicity and offset configuration index and reports a RI according to the set periodicity and offset. The periodicity is an integer and reporting a RI reports with equal the product of the periodicity and a period of reporting of the channel quality indicator (CQI) and the preceding matrix indicator (PMI).

    摘要: Transmission with multiple antennas in a wireless network is performed by transmitting a plurality of reference sequences (RS) from a UE. A first RS s1[k] is produced using a first cyclic shift and a base sequence s0[k], wherein k={1, 2 . . . K} is an element index. A second RS s2[k] is produced using a second cyclic shift and s0[k]. A first symbol sequence x1[k] is produced using at least s1[k] and s2[k], for at least one k. A second symbol sequence x2[k] is produced using at least s1[k] and s2[k], for at least one k. x1[k] is transmitted using a first transmit antenna and x2[k] is transmitted using a second transmit antenna.
