    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: This invention is a method of downlink, multiuser, multiple input, multiple output communication between a single base station and plural user equipment. Resource buffers are distributed into sub-bands. Each user equipment is assigned to a sub-band with at least one sub-band assigned plural user equipment. The base station transmits user equipment according to assigned sub-bands. A single user equipment may be assigned one sub-band while plural user equipment are assigned to another sub-band. In one embodiment the base station has N transmit antennas. N user equipment is assigned to a first sub-band and less than N user equipment is assigned to a second sub-band. In another embodiment a first second user equipment is assigned a first sub-band and the first and a third user equipment are assigned to a second sub-band.

    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.

    摘要: This invention prevents a periodically reported Rank Indicator from interfering with a similarly periodically reported wideband and subband channel quality indicator. Such interference is disadvantageous because it may eliminate wideband channel quality indicator reporting or eliminate each first bandwidth part of subband channel quality indicator reporting. Proper selection of the rank indicator reporting periodicity and offset relative to the wideband and subband channel quality indicator reporting periodicity prevents this interference.

    摘要: A method of mapping data in a wireless communication system is disclosed. The method includes forming a first frame (504) having plural positions at a first transmitter (eNB 1, 200). The first frame has a first plurality of reference signals (500). A second frame (508) has plural positions corresponding to the plural positions of the first frame and is formed at a second transmitter (eNB 2, 450) that is remote from the first transmitter. The second frame has a second plurality of reference signals (506). A plurality of data signals (S1, S2) is inserted into the first frame at positions that are not occupied by either the first or second plurality of reference signals. The plurality of data signals (S1, S2) is inserted into the second frame at positions that are not occupied by either the first or second plurality of reference signals. The first and second frames are transmitted to a remote receiver (UE 1, 106).
