摘要： A base station may transmit at varied power levels. Subscriber stations receiving the power levels can transmit noise information back to the base station. As a result, co-channel interference can be determined from the varied power transmissions, either in the base station or in the subscriber station. In addition, in some embodiments, the transmissions may include different phases so that the phase of the co-channel interference may be determined as well.

摘要： Techniques are described that can be used to perform one or more of the following actions in order to reduce signal interference between WLAN and BlueTooth radios that are proximate to one another. One action is to selectively reduce a filter bandwidth in a WLAN radio applied to a received WLAN radio signal to reduce BlueTooth signal interference. An additional or alternative action is to selectively indicate a WLAN radio channel bandwidth larger than a channel bandwidth used for the WLAN radio so that the BlueTooth radio avoids transmitting over the indicated channel bandwidth. An additional or alternative action is to selectively reduce BlueTooth transmitter power in response to antenna isolation between BT and WLAN radio being less than a first threshold in order to reduce the likelihood of WLAN radio front end saturation.

摘要： A first N×M codebook of a first rank M may be used to generate a second N×(N−M) codebook of a second rank (N−M). This second codebook is both orthogonal and complementary to the first codebook. In practice, this may reduce storage requirements in closed-loop MIMO beamforming, because the second codebook may be dynamically generated as needed by a base station and/or a mobile station. In some cases, a higher rank beamforming matrix or precoding matrix may be formed from a lower rank (e.g., one or two) beamforming matrix or precoding matrix. Also, a novel way to generate the rotation matrix Qv(t-1) is disclosed.
摘要翻译：可以使用第一等级M的第一N×M码本来生成第二等级（N-M）的第二N×（N-M）个码本。该第二码本与第一码本正交和互补。实际上，这可能减少闭环MIMO波束成形中的存储要求，因为第二码本可以根据基站和/或移动台的需要动态生成。在一些情况下，可以从较低等级（例如，一个或两个）波束形成矩阵或预编码矩阵形成较高秩波束形成矩阵或预编码矩阵。另外，公开了生成旋转矩阵Qv（t-1）的新颖方式。
