    • Methods and apparatus enabling a wireless network to generate data that can be used by a receiver (e.g., UE) to resolve the contributions of individual transmitters, such as to determine its location without resort to external devices such as GPS satellites. In one embodiment, the wireless network comprises a single frequency network (SFN), and a unique base station identifier is embedded within the data, and encoded in a manner which allows the UE to calculate path characteristics (such as path latency, and Direction of Arrival) to triangulate its position. In one variant, the data encoding comprises weighting frames of data from different base stations using an orthogonal matrix. Advantageously, the encoding and embedded identifier are also transparent to legacy UE, thereby allowing for implementation with no infrastructure or UE modifications other than software. Network and user apparatus implementing these methodologies, and methods of doing business, are also disclosed.

    • Methods and apparatus that enable one or more wireless networks to minimize inter-cellular interference (ICI) at a receiver. In one embodiment, the network comprises an OFDM-based cellular network, and the method comprises utilizing a priori knowledge of non-data portions of signals from multiple base stations in order to schedule transmissions. In one variant, these non-data portions comprise pilot tones; the pilot tones can be scheduled onto various time-frequency resources of the network so as to minimize ICI. The mobility context of the receiver can also be used as a basis for dynamically adjusting the pilot tone density. In another variant, preceding (e.g., Tomlinson-Harashima precoding) can be applied to "shape" the non-data portions of the transmitted signals so as to mitigate ICI. In yet other variants, frame preambles and learning sequences are used as the basis for invoking selective transmission time shifts across the potentially interfering base stations so as to minimize ICI.

    • Methods and apparatus to enable a wireless network system to dynamically change information channel message broadcasts. In one aspect, cellular network systems optimize pilot channel message delivery based at least in part on one or more network parameters. Base stations and/or cellular devices can dynamically configure the pilot channel message delivery or reception based on the network parameters. For example, such flexible pilot channel message delivery may more frequently deliver prioritized pilot channel messages, and less frequently broadcast low priority messages. Cellular subscribers with appropriately enabled user equipment may improve their power and applications performance through implementation of the invention. Furthermore, base stations may reclaim the freed cellular resources to support other services. Legacy subscribers are advantageously not affected.
    • 使无线网络系统动态地改变信息信道消息广播的方法和装置。 在一个方面,蜂窝网络系统至少部分地基于一个或多个网络参数优化导频信道消息传递。 基站和/或蜂窝设备可以基于网络参数动态配置导频信道消息传递或接收。 例如,这种灵活的导频信道消息传递可以更频繁地传送优先级导频信道消息,并且较不频繁地传送低优先级消息。 具有适当启用的用户设备的蜂窝用户可以通过实施本发明来提高其功率和应用性能。 此外,基站可以回收释放的蜂窝资源来支持其他业务。 传统用户有利地不受影响。
