The methods include deploying a network synchronization calibration unit at a location within receiving range of a plurality of direct path reference signals transmitted by the plurality of emitter antennas. The synchronization calibration unit receives the plurality of direct path reference signals and one or more reflected reference signals, which are then separated from one another to identify the direct path reference signals when a signal strength of one direct path reference signal is less than a signal strength of a reflected reference signal. A set of data is collected from the reflected reference signals that is indicative of the timing offset and that set of data is analyzed to estimate the timing offset.

A navigation system is disclosed. In embodiments, the navigation system includes one or more transmitting devices configured to generate one or more transmission signals by performing one or more frequency-modulation operations on a carrier signal to encode communication data onto the carrier signal, and performing one or more amplitude-modulation operations on the carrier signal to encode navigational data onto the carrier signal. In embodiments, the one or more transmitting devices are further configured to transmit the one or more transmission signals to one or more receiving devices, wherein a receiving device of the one or more receiving devices is configured to extract the navigational data from the one or more transmission signals and determine a position of the receiving device based at least in part on the extracted navigational data.

In one aspect, the present invention provides a simple method of signaling reference signal muting information to receiving radio equipment, such as items of user equipment (UEs). The reference signals may be positioning reference signals and/or cell-specific reference signals, for example. In one or more embodiments, the present invention proposes a general solution whereby the receiving radio equipment is informed not only on whether muting is used in general in a cell, but also the particular timing and formatting of such muting. Further, the contemplated method provides for the use of dynamic muting patterns, and thus avoids the need for statically defined muting patterns, and provides for coordinated muting control, across two or more network cells. In at least one embodiment, static or less dynamic aspects of the muting configuration is signaled via higher-layer signaling, while lower-layer signaling is used to signal more dynamic aspects of the muting configuration.
