Ad-Hoc Control Protocol Governing Use of an Unlicensed or Shared Radio Frequency Band
First Claim
1. A method for sharing use of a radio frequency band by a plurality of devices that may operate with different communication protocols, the method comprising sharing information among the devices using a common signaling format so that the devices may self-regulate their use of the radio frequency band.

Abstract
Systems and methods to enable different types of radio communication devices to communicate using a common language in order to enable the devices to regulate their use of the spectrum. Each device participating in the ad hoc control channel (ACC) protocol transmits information using a common signal format that each of the other participant devices is capable of recognizing, in order to share information about how it uses the radio frequency band. Each device receives the information transmitted by other participant devices and based on that information, controls one or more of its operational parameters that impact usage of the radio frequency band. The ACC protocol enables devices of the same or different type to harmonize (instead of alienate) themselves with each other by allowing them to communicate about their usage of the radio frequency band using a common signaling framework. Improvement can be achieved in spectrum efficiency and ultimately provide a more reliable and enjoyable experience for the end user of a device that operates in that radio frequency band.

- 20. A method for operating a first radio communication device that operates in a radio frequency band shared with a plurality of other radio communication devices, the method comprising generating a signal for transmission from the first radio communication device to be received by the plurality of other radio communication devices, wherein the signal contains information describing how the first radio communication device uses the radio frequency band.
- 37. In combination, a modem that generates a baseband signal for radio transmission and recovers a baseband signal from a received radio signal, and a control processor coupled to the modem that supplies data for transmission to the modem and processes data recovered from a received radio signal by the modem, wherein the control processor generates spectrum usage data coupled to the modem to be formatted for transmission to other radio communication devices operating in a radio frequency band, wherein the spectrum usage data comprises information describing how a radio communication device associated with the modem and control processor uses the radio frequency band, and wherein the control processor processes received spectrum usage data derived from a received baseband signal that describes how at least one other radio communication device uses the radio frequency band, and wherein the control processor generates control signals to control one or more operational parameters of the radio communication device that impact usage of the radio frequency band based on the received spectrum usage data.
- 45. A processor readable medium encoded with instructions that, when executed by a processor, cause the processor to perform a step of generating a signal for transmission from a first radio communication device to be received by a plurality of other radio communication devices, wherein the signal contains information describing how the first radio communication device uses a radio frequency band in which it operates.
