摘要： A method and apparatus for selecting an antenna mapping in multiple-in/multiple-out (MIMO) enabled wireless communication networks. A candidate set of currently available antenna mappings is determined based upon measured long term channel conditions. An antenna mapping is selected from the candidate set, and the mapping is calibrated with a selected antenna mapping of a receiving wireless transmit/receive unit (WTRU). When the selected mappings are calibrated, packet data transmission begins. In an alternative embodiment, a calibration training frame (CTF) is used to calibrate multiple antenna mappings simultaneously or sequentially. Also disclosed are physical layer and medium access control layer frame formats for implementing antenna mapping selection according to the invention.

摘要翻译： 一种用于在启用多输入多输出（MIMO）的无线通信网络中选择天线映射的方法和装置。 基于测量的长期信道条件确定当前可用的天线映射的候选集。 从候选集中选择天线映射，并且利用接收无线发射/接收单元（WTRU）的选定的天线映射校准映射。 当所选择的映射被校准时，分组数据传输开始。 在替代实施例中，校准训练帧（CTF）用于同时或顺序地校准多个天线映射。 还公开了根据本发明的用于实现天线映射选择的物理层和媒体接入控制层帧格式。
