Definitions

  • the present disclosure generally relates to generating estimates of RF signal loss that are derived from and/or based on measured RF signal losses of an environment in which a receiver is disposed. Specifically, the present disclosure facilitates generation of accurate RF signal loss estimates for RF communications relative to a transmitter, receiver, and/or transceiver (any of which may be individually or collectively referred to as a radio station) that is located within a building or other structure that affects the propagation of the RF signal originating from or received at the radio station.
  • the loss estimates may be utilized to generate an attenuation profile, especially for indoor operation, for a stationary in-building radio station.
  • the attenuation profile provides information regarding the loss of RF communications relative to the radio station.
  • Such an attenuation profile as part of channel state or status information may be utilized in a number of contexts, which are disused in greater detail below.
  • the implementation of shared spectrum systems that utilize shared spectrum resources may account for a number of considerations regarding proposed use of a shared resource by a radio station. For example, a number of legacy services (e.g., licensed spectrum use such as licensed broadcasters, radar installations, or other high priority spectrum uses that must be free from radio interference by other spectrum users) may be considered when developing a shared spectrum system. Given the potential importance of such legacy services, newly added stations (e.g., through licensure, provision of rights, or other authorization to utilize the spectrum) in the shared spectrum system may be governed by the shared spectrum controller.
  • legacy services e.g., licensed spectrum use such as licensed broadcasters, radar installations, or other high priority spectrum uses that must be free from radio interference by other spectrum users
  • newly added stations e.g., through licensure, provision of rights, or other authorization to utilize the spectrum
  • GPS signals contain ephemeris data that may include or be utilized to determine the location of a space vehicle generating the GPS signal.
  • the location of the sounding transmitter in the form of the GPS space vehicle may be known such that a direction of incidence of the GPS signal relative to the receiver may be resolved.
  • the signal loss value may comprise a quantitative comparison between carrier to thermal nose power ratios for a measured signal relative to a signal in free space. That is, the signal loss value may comprise a measure derived based on a measured signal to noise ratio (SNR) of a measured signal relative to a known SNR for the sounding signal in free space.
  • SNR measured signal to noise ratio
  • Other appropriate values for the signal loss value may be utilized without limitation that quantify the amount of power loss of the signal due to the structure 105 and/or environment surrounding the receiver 100.
