Abstract: A wireless telecommunication device conducts base station pages at large intervals, such as 30 seconds, rather than the more conventional 0.5 to 4 seconds. The network processes calls placed to that telecommunication device in accordance with an SMS (Short Messaging Service) type protocol rather than a conventional voice call protocol. Particularly, the network sends an SMS to the telephone indicating that a third party is calling (hereinafter termed a “pre-call SMS”). The pre-call SMS indicates the telephone number of the third party. The user of the telephone may call the third party back. In accordance with this protocol, the need to page at very short intervals so as to permit a telephone call to be established in “real-time” is eliminated. Therefore, the paging interval can be increased substantially, thereby substantially prolonging battery charge lifetime of the telephone. In accordance with another aspect of the invention, when a cellular telephone sends a pre-call SMS, it temporarily decreases its paging interval to a more conventional interval such as 0.5 seconds for a predetermined period of time (e.g., 1-5 minutes) after placing a call so that, if the called party returns the call, the calling party will receive the return call in real-time and be able to answer the incoming call and establish a voice call.

Abstract translation: 无线电信设备以大的时间间隔进行基站页面，例如30秒，而不是更常规的0.5至4秒。 网络根据SMS（短消息服务）类型协议而不是传统语音呼叫协议来处理对该电信设备的呼叫。 特别地，网络向电话发送指示第三方正在呼叫的SMS（以下称为“预呼叫SMS”）。 预通话短信表示第三方的电话号码。 电话的用户可以将第三方呼叫回来。 根据该协议，消除了以非常短的间隔寻呼以便允许以“实时”建立电话呼叫的需要。 因此，可以大幅度地提高寻呼间隔，从而大大延长电话的电池充电寿命。 根据本发明的另一方面，当蜂窝电话发送预呼叫SMS时，它将其寻呼间隔临时减小到更常规的时间间隔，例如0.5秒，预定时间段（例如，1-5分钟）之后 拨打电话，如果被叫方返回呼叫，主叫方将实时接收返回呼叫，并能够接听来电并建立语音电话。

Abstract: A method is described that enables maximum-likelihood (ML) demodulation for MIMO communications over frequency-selective channels. An equalizer is typically employed to suppress inter-symbol interference (ISI) due to frequency-selectiveness of the channel, but the noise of the equalizer output can be highly correlated such that standard ML-MIMO demodulations cannot directly apply. The method comprises first constructing equivalent post-equalization MIMO channel and noise covariance matrix, and then de-correlating the equalizer output so that ML or near-ML MIMO demodulations can be applied to improve the performance. Additionally, successive ISI cancellation (SIC) is described for further performance improvement.

Abstract translation: 描述了一种能够通过频率选择信道进行MIMO通信的最大似然（ML）解调的方法。 通常采用均衡器来抑制由于信道的频率选择性引起的符号间干扰（ISI），但是均衡器输出的噪声可以高度相关，使得标准ML-MIMO解调不能直接应用。 该方法包括首先构建等效的后均衡MIMO信道和噪声协方差矩阵，然后将均衡器输出去相关，使ML或近ML MIMO解调可以应用于提高性能。 另外，为了进一步提高性能，描述了连续的ISI取消（SIC）。

Abstract: Methods and apparatus are described that provide carrier-phase difference (CPD) acquisition via signaling protocols between communicating devices. The random CPD between two disjoint devices can be measured by the signaling protocols described herein. With the availability of the CPD, a device is also able to acquire its outgoing channel (transmit channel) information, thus avoiding the channel information feedback that is being considered and/or practiced in some wireless communications systems. Also described are methods and apparatus that use the CPD to synchronize the clocks of two or more devices and that track the time-variations of the CPD for reliable CPD measurement and tracking loop operations. Applications of the described methods and apparatus include wireless multipoint broadcast systems, also known as coordinated multipoint transmission, or CoMP, in LTE (long-term evolution)-advanced systems, point-to-point wireless MIMO systems, and general wireless device networks.
