用于MIMO通信的有效的预编码信息验证的方法和设备
Abstract:
本发明提供了一种用于多输入多输出MIMO无线通信系统中的有效预编码矩阵验证的方法和设备。无线发射/接收单元WTRU向e节点B发送预编码矩阵索引PMI。e节点B发送验证消息，该验证消息包含用以指示WTRU的PMI与e节点B的PMI是否相同的PMI指示符。如果WTRU的PMI与e节点B的PMI相同，则e节点B发送仅PMI指示符，否则e节点B会向WTRU发送PMI指示符以及e节点B的PMI。多个PMI可以被同时发送，并且PMI可以被划分成多个群组。PMI指示符可以附着于控制信令或被插入到控制信令中。PMI验证消息可以通过控制信令或使用专用基准信号以信号发送至WTRU。
Abstract(English):

A method and apparatus for efficient precoding matrix verification in a multiple-input multiple-output MIMO wireless communication system are disclosed. A wireless transmit/receive unit WTRU sends a precoding matrix index PMI to an eNodeB. The eNodeB sends a verification message including a PMI indicator indicating whether or not the PMI of the WTRU and a PMI of the eNodeB are identical. If the PMI of the WTRU and of the eNodeB are identical, the eNodeB sends just a PMI indicator otherwise the eNodeB sends to the WTRU a PMI indicator and the PMI of the eNodeB. A plurality of PMIs may be sent simultaneously, and the PMIs may be partitioned into a plurality of groups. The PMI indicator may be either attached to or inserted into control signaling. PMI validation messages can be signaled to WTRU by control signaling or use of a dedicated reference signal.
