    摘要： A method and apparatus for transmitting and receiving a wireless transmission of a plurality of data streams in a wireless communication system having a plurality of nodes is disclosed. Each node has multiple antennas. The method involves receiving first and second data streams from respective first and second nodes at a receiver node, causing the receiver node to generate a receive filter for decoding each of the received data streams, and causing the receiver node to transmit receive filter information for each of the first and second data streams, the receive filter information facilitating precoding of the first and second data streams for simultaneous transmission within a common frequency band to the receiver node.

    摘要： A system and method for multi-cell joint codebook feedback in wireless communications systems are provided. A method for operations at a communications device receiving joint transmissions from a plurality of communications controllers includes estimating a channel between the communications device and each communications controller in the plurality of communications controllers, thereby producing a plurality of channel estimates, computing feedback information based on the plurality of channel estimates, transmitting the feedback information, and receiving simultaneous transmissions from the plurality of communications controllers. The computing is based on a phase adjustment for the plurality of channels or a joint optimization of the plurality of channels, and the simultaneous transmissions are precoded based on the feedback information.

    摘要： Aspects of the invention are directed to a transmit diversity method for use in a wireless terminal having a plurality of antennas and a wireless terminal configured to implement the method. The transmit diversity method includes using a different orthogonal sequence for each antenna, or group of antennas, for transmitting an uplink control channel from a wireless terminal to a base station. A first step of the method involves assigning at least one orthogonal sequence to one or more of the plurality of antennas, each of the plurality of antennas being assigned at least one orthogonal sequence. Once the orthogonal sequence is assigned, a further step involves scrambling a signal to be transmitted on the physical uplink control channel (PUCCH) using the at least one orthogonal sequence for each antenna thereby producing a scrambled PUCCH for transmission by each antenna. The scrambled PUCCH can then be transmitted on the plurality of antennas.
