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： 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： To perform rank adaptation for a mobile station in a wireless network, it is determined whether the mobile station is fast moving. In response to determining that the mobile station is fast moving, an open loop multi-antenna mode is selected to perform wireless communication between the mobile station and a base station. Also, selection is made from among plural ranks for the wireless communication according to the open loop multi-antenna mode between the mobile station and the base station.
