| 主权项 | 1. A method comprising: using a precoding code book for controlling transmissions from four antennas of a device, said code book consisting of a plurality of entries comprising different antenna pair combination whereby one or two antenna pairs are selected for transmission, wherein each of said entries are such that only a single layer is mapped to each antenna that is selected for transmission. | ||
