| 发明名称 | Base station and method for selecting best transmit antenna(s) for signaling control channel information | ||
| 摘要 | A base station is described herein which implements a method that uses different aspects of reported channel quality information (CQI) measurements to help select the “best” transmit antenna(s) on which to transmit control channel information to mobile terminal(s). The base station can also transmit a format indicator to communicate the assigned control channel transmit antenna(s) and the assigned data transmit antenna(s) to the mobile terminal(s). | ||

| 主权项 | 1. A method for selecting one or more transmit antennas from which to transmit control channel information to one or more receivers, said method comprising the steps of: receiving channel quality information measurements from the one or more receivers, wherein said channel quality information measurements are a function of the channel quality of downlink data channels; and, analyzing the received channel quality information measurements to select which transmit antenna(s) to be used to transmit the control channel information independently from which antenna(s) are selected for data transmission, wherein when said received channel quality information measurements have a specific antenna detection ordering then said analyzing step results in selecting the transmit antenna(s) which are going to be detected first by the one or more receivers. | ||
