Spectrum sharing based on signal-based shared access
First Claim
1. A process for sharing a spectrum, comprising:
- measuring, by a primary wireless system, a quality of signal of interest of the primary wireless system over an entire spectrum band while one or more secondary wireless systems are using all or a portion of the entire spectrum band owned by the primary wireless system, wherein the quality of the signal of interest comprising a signal quality performance in a physical layer of the primary wireless system;
comparing the quality of the signal of the primary wireless system with a minimum threshold level of the primary wireless system to determine a signal quality indicator;
upon measuring and comparing of the quality of the signal, transmitting, from the primary wireless system, the signal quality indicator of the primary wireless system to the one or more secondary wireless systems irrespective of a level or value of the signal quality indicator; and
receiving, by the primary wireless system, spectrum usage information from the one or more secondary wireless systems to ensure that the one or more secondary wireless systems comply with an agreement between the primary wireless system and the one or more secondary wireless systems, whereinthe signal quality indicator is related to an associated action message, wherein the associated action message represents a desired level of action required by the primary wireless system,the primary wireless system is the owner of the entire spectrum band in a primary network and licenses use of all or a portion of the entire spectrum band to the one or more secondary wireless systems eliminating a protection zone or exclusion zone, andthe secondary wireless system is a licensee of the primary wireless system and is able to overlap in coverage with the primary wireless system so long as the quality of the signal of interest for the primary wireless system is acceptable.

Abstract
A process for sharing spectrum based on signal based shared access (SSA) includes measuring by a primary wireless system, the quality of a signal of interest (SOI) over a shared spectrum band. The process includes transmitting a signal quality indicator related to an associated action message from the primary wireless system to a second wireless system. The process also includes receiving spectrum usage information by the primary wireless system from the second wireless system. The process further includes determining by the primary wireless system whether the second wireless system complies with spectrum sharing band conditions between the primary wireless system and the second wireless system.

8. A process for sharing a spectrum, comprising:
-
receiving, at a secondary wireless system, a signal quality indicator of a primary wireless system over an entire spectrum band or for one or more shared sub-frequency blocks of the spectrum band while the secondary wireless system is using the entire spectrum band or the one or more shared sub-frequency blocks within the entire spectrum band, wherein the signal quality indicator of the primary wireless system is related to a signal quality performance in a physical layer of the primary wireless system; transmitting, by the secondary wireless system, spectrum usage information to ensure that the secondary wireless system is complying with an agreement between the primary wireless system and the second wireless system; and based on the signal quality indicator, adjusting, by the secondary wireless system, a power level of user equipment or one or more wireless systems operating under the spectrum band, switching the user equipment or the secondary wireless system from operating under the entire spectrum band or the one or more shared sub-frequency blocks within the entire spectrum band to operate under another spectrum band outside of the entire spectrum band not owned by the primary wireless system, or maintain the power level of the user equipment or the secondary wireless system to continue to operate under the entire spectrum band, wherein the primarily wireless system is the owner of the entire spectrum band in a primary network and licenses use of the entire spectrum band or the one or more shared sub-frequency blocks within the entire spectrum band to the secondary wireless system eliminating a protection zone or exclusion zone, and the secondary wireless system is a licensee of the primary wireless system and is able to overlap in coverage with the primary wireless system so long as the quality of the signal of interest for the primary wireless system is acceptable, and the signal quality indicator is related to an associated action message, wherein the associated action message represents a desired level of action required by the primary wireless system. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system, comprising:
-
a primary wireless system configured to share a spectrum band with one or more secondary wireless systems, wherein the primary wireless system is configured to; measure a quality of a signal of interest of the primary wireless system over an entire spectrum band while one or more secondary wireless systems are using the spectrum band owned by the primary wireless system, wherein the quality of the signal of interest comprising a signal quality performance in a physical layer of the primary wireless system, comparing the quality of the signal of the primary wireless system with a minimum threshold level of the primary wireless system to determine a signal quality indicator, upon measuring and comparing of the quality of the signal, transmit the signal quality indicator of the primary wireless system to the one or more secondary wireless systems irrespective of a level or value of the signal quality indicator, and receiving, by the primary wireless system, spectrum usage information from the one or more secondary wireless systems to ensure that the one or more secondary wireless systems comply with an agreement between the primary wireless system and the one or more secondary wireless systems; and the one or more secondary wireless systems are configured to; receive the signal quality indicator from the primary wireless system, and apply interference mitigation techniques to avoid harmful interference with the primary wireless system, wherein the primary wireless system is the owner of the entire spectrum band in a primary network and licenses use of the spectrum band to the one or more secondary wireless systems eliminating a protection zone or exclusion zone, and the one or more secondary wireless systems are licensees of the primary wireless system and is able to overlap in coverage with the primary wireless system so long as the quality of the signal of interest for the primary wireless system is acceptable, and the signal quality indicator is related to an associated action message, wherein the associated action message represents a desired level of action required by the primary wireless system. - View Dependent Claims (17, 18, 19)
