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.

Abstract: Multipoint broadcasting requires the base stations to be phase-synchronized. Methods and apparatus are described that provide phase synchronization of base stations with the downlink-channel phase feedback by mobile users. Also described are methods and apparatus that make phase synchronization of base stations independent of multipoint-broadcast sessions, thus reducing the synchronization overhead and improving network capacity. The methods and apparatus utilize model-based downlink-channel phase feedback that reduces most of the feedback overhead. Applications of the described methods and apparatus include wireless multipoint broadcast systems, also known as coordinated multipoint transmission, or CoMP, in LTE-A (long-term evolution, advanced) systems, and frequency and phase synchronization of a cluster of base stations, or more generally, of a cluster of wireless devices.

Abstract: Large-dimension MIMO and multipoint broadcasting in new generation of wireless networks create high demand for various types of pilots in transmission signals for channel estimation, data demodulation, synchronization, etc. More pilots, as in existing networks, use more resources and thus diminish the network capacity. Methods and apparatus of heterogeneous pilots are disclosed. A heterogeneous pilot has its own signal characteristics that are different from the primary information-bearing signals in the network. Heterogeneous pilots can be spread-spectrum signals in an OFDM-based wireless network. Heterogeneous pilots use no network resources, and can be as many as desired, and can be designed to have versatile utilities. Also described are methods and apparatus of heterogeneous pilot cancellation that minimizes the interference of heterogeneous pilots on the primary information-bearing signals. Applications of the described methods and apparatus include OFDM-based wireless cellular networks, such as LTE-advanced and Wireless LAN.

Abstract: A method and apparatus are disclosed for detecting a pilot signal in a wireless receiver using coherent combining/noncoherent detection techniques. Coherent combining/noncoherent detection techniques are used to detect the pilot signal whenever the receiver is already frequency locked, or otherwise known to have a small frequency offset Conventional noncoherent combining/noncoherent detection techniques are utilized to initially acquire the timing of the forward channel. Once the receiver is frequency locked, coherent combining/noncoherent detection techniques may be used to continuously detect the pilot signals. After the receiver is frequency locked, the residue frequency error is small over several consecutive correlator outputs The correlator outputs can thus be combined coherently (since the frequency error is known to be small), and the phase dependency is then eliminated by noncoherent detection.

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。
