BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
This invention relates generally to communication devices and more particularly to the communication devices that communicate with multiple networks in multiple frequency bands.
2. Description of Related Art
Wireless communication systems are known to support wireless communications between wireless communication devices affiliated with the system. Such wireless communication systems range from national and/or international cellular telephone systems to point-to-point in-home wireless networks. Each type of wireless communication system is constructed, and hence operates, in accordance with one or more standards. Such wireless communication standards include, but are not limited to IEEE 802.11, 802.15, 802.16, long term evolution (LTE), Bluetooth, advanced mobile phone services (AMPS), digital AMPS, global system for mobile communications (GSM), code division multiple access (CDMA), wireless application protocols (WAP), local multi-point distribution services (LMDS), multi-channel multi-point distribution systems (MMDS), and/or variations thereof.
An IEEE 802.11 compliant wireless communication system includes a plurality of client devices (e.g., laptops, personal computers, personal digital assistants, etc., coupled to a station) that communicate over a wireless link with one or more access points. As is also generally understood in the art, many wireless communications systems employ a carrier-sense multiple access (CSMA) protocol that allows multiple communication devices to share the same radio spectrum. Before a wireless communication device transmits, it “listens” to the wireless link to determine if the spectrum is in use by another station to avoid a potential data collision. In other systems, transmissions can be scheduled using management frames or power save multi-poll (PSMP), for example. In many cases, the transmitting device (e.g., a client device or access point) transmits at a fixed power level regardless of the distance between the transmitting device and a targeted device (e.g., station or access point). Typically, the closer the transmitting device is to the targeted device, the less error there will be in the reception of the transmitted signal.
A cognitive radio is a wireless communication device that can adjust transmission or reception parameters to communicate efficiently to avoiding interference. This alteration of parameters can be based on the active monitoring of several factors in the external and internal radio environment, such as radio frequency spectrum, user behavior and network state.
When one or more of these communication devices is mobile, its transmit and receive characteristics can change with the motion of the device, as it moves closer or farther from a device it is communication with, and as the transmission environment changes due to the devices position with respect to reflecting members, interfering stations, noise sources, etc.
The limitations and disadvantages of conventional and traditional approaches will become apparent to one of ordinary skill in the art through comparison of such systems with the present invention.

Power management circuit 95 can operate from one or more batteries, line power, an inductive power received from a remote device, a piezoelectric source that generates power in response to motion of the integrated circuit and/or from other power sources, not shown. In particular, power management module 95 can selectively supply power supply signals of different voltages, currents or current limits or with adjustable voltages, currents or current limits in response to power mode signals received from the IC 50. While shown as an off-chip module, PMU 95 can be alternatively implemented as an on-chip circuit.

In operation, the RF transceivers 73 . . . 73′ generate outbound RF signals from outbound data and generate inbound data from inbound RF signals to communication with a plurality of networks, such as networks 2, 4, 6, 8, etc. In an embodiment of the present invention, the IC 50 is a system on a chip integrated circuit that includes at least one processing device. Such a processing device, for instance, processing module 225, may be a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions.

Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, and/or any device that stores digital information. Note that when the IC 50 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the associated memory storing the corresponding operational instructions for this circuitry is embedded with the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry.
Also note that while certain modules of communication device 125 are shown to be included on IC 50 while others are not, IC 50 is shown for illustrative purposes and may include more or less of the modules of communication device 125, depending on the particular implementation. Further, communication device 125 can include additional modules or fewer modules than those specifically shown. In operation, the IC 50 executes operational instructions that implement one or more of the applications (real-time or non-real-time) attributed to communication devices 125 as discussed above and in conjunction with FIGS. 1-3.
FIG. 5 is a schematic block diagram of an embodiment of RF transceiver 123, such as transceiver 73 or 73′, in accordance with the present invention. The RF transceiver 123 includes an RF transmitter 129, and an RF receiver 127. The RF receiver 127 includes a RF front end 140, a down conversion module 142 and a receiver baseband processing module 144 that operate under the control of control signals 141. The RF transmitter 129 includes a transmitter baseband processing module 146, an up conversion module 148, and a radio transmitter front-end 150 that also operate under control of control signals 141.
As shown, the receiver and transmitter are each coupled to an antenna through an antenna interface 171 and a diplexer (duplexer) 177, such as antenna interface 72 or 74, that couples the transmit signal 155 to the antenna to produce outbound RF signal 170 and couples inbound signal 152 to produce received signal 153. Alternatively, a transmit/receive switch can be used in place of diplexer 177. While a single antenna is represented, the receiver and transmitter may share a multiple antenna structure that includes two or more antennas. In another embodiment, the receiver and transmitter may share a multiple input multiple output (MIMO) antenna structure, diversity antenna structure, phased array or other controllable antenna structure that includes a plurality of antennas. Each of these antennas may be fixed, programmable, and antenna array or other antenna configuration.
In operation, the transmitter receives outbound data 162 from other portions of its a host device, such as a communication application executed by processing module 225 or other source via the transmitter processing module 146. The transmitter processing module 146 processes the outbound data 162 in accordance with a particular wireless communication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce baseband or low intermediate frequency (IF) transmit (TX) signals 164 that contain outbound data 162. The baseband or low IF TX signals 164 may be digital baseband signals (e.g., have a zero IF) or digital low IF signals, where the low IF typically will be in a frequency range of one hundred kilohertz to a few megahertz. Note that the processing performed by the transmitter processing module 146 can include, but is not limited to, scrambling, encoding, puncturing, mapping, modulation, and/or digital baseband to IF conversion.
The up conversion module 148 includes a digital-to-analog conversion (DAC) module, a filtering and/or gain module, and a mixing section. The DAC module converts the baseband or low IF TX signals 164 from the digital domain to the analog domain. The filtering and/or gain module filters and/or adjusts the gain of the analog signals prior to providing it to the mixing section. The mixing section converts the analog baseband or low IF signals into up-converted signals 166 based on a transmitter local oscillation.
The radio transmitter front end 150 includes a power amplifier and may also include a transmit filter module. The power amplifier amplifies the up-converted signals 166 to produce outbound RF signals 170, which may be filtered by the transmitter filter module, if included. The antenna structure transmits the outbound RF signals 170 to a targeted device such as a RF tag, base station, an access point and/or another wireless communication device via an antenna interface 171 coupled to an antenna that provides impedance matching and optional bandpass filtration.
The receiver receives inbound RF signals 152 via the antenna and off-chip antenna interface 171 that operates to process the inbound RF signal 152 into received signal 153 for the receiver front-end 140. In general, antenna interface 171 provides impedance matching of antenna to the RF front-end 140, optional bandpass filtration of the inbound RF signal 152 and optionally controls the configuration of the antenna in response to one or more control signals 141 generated by processing module 225.
The down conversion module 142 includes a mixing section, an analog to digital conversion (ADC) module, and may also include a filtering and/or gain module. The mixing section converts the desired RF signal 154 into a down converted signal 156 that is based on a receiver local oscillation, such as an analog baseband or low IF signal. The ADC module converts the analog baseband or low IF signal into a digital baseband or low IF signal. The filtering and/or gain module high pass and/or low pass filters the digital baseband or low IF signal to produce a baseband or low IF signal 156. Note that the ordering of the ADC module and filtering and/or gain module may be switched, such that the filtering and/or gain module is an analog module.
The receiver processing module 144 processes the baseband or low IF signal 156 in accordance with a particular wireless communication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce inbound data 160. The processing performed by the receiver processing module 144 includes, but is not limited to, digital intermediate frequency to baseband conversion, demodulation, demapping, depuncturing, decoding, and/or descrambling.
Further, processing module 225 generates one or more control signals 141 to configure or adapt the RF transceiver 123 to communication with one or more of the networks 2, 4, 6 and 8. In operation, processing module 225 generates control signals 141 to modify the transmit and/or receiver parameters of the RF transceiver 125 such as protocol parameters, data rates, modulation types and other data parameters used by receiver processing module 144 and transmitter processing module 146, frequency bands, channels and bandwidths, filter settings, gains, power levels, ADC and DAC parameters, and other parameters used by RF front-end 140, radio transmitter front-end 150, down conversion module 142 and up conversion module 148, as well as antenna configurations used by antenna interface 171 to set the beam pattern, gain, polarization or other antenna configuration of the antenna.
The control signals 141 can be analog signals, digital signals, discrete-time signals of other signals that control the modules of RF transceiver 123 to adapt to communication via different networks. For example, in one mode of operation, communication device 125 includes a plurality of different transceivers 73 . . . 73′, that are each designed and implemented by a particular RF transceiver 123 for communicating with one of the plurality of networks 2, 4, 6 and/or 8. Each of these RF transceivers 123 can be selectively enabled or disabled via control signals 141 to operate under the control of processing module 225 to communicate with its corresponding network 2, 4, 6 or 8 when required. In another embodiment of the present invention one or more of the transceivers 73 . . . 73′ is implemented via a cognitive radio transceiver or other flexible RF transceiver 123 that can be configured to communicate with different networks based on a selected mode of operation. For example, such a flexible RF transceiver 123 can be configured to operate as either a Bluetooth transceiver, a GSM transceiver or a 802.11g transceiver based on the generation of the control signals 141 to implement the corresponding transmit and receive characteristics. Further details regarding particular conditions for generating control signals 141 will be discussed in conjunction with FIGS. 6-51 that follow.
FIG. 6 is a schematic block diagram of another embodiment of a communication device 125 in accordance with the present invention. In particular, a communication device is shown that includes many common elements shown in conjunction with FIG. 4. In this embodiment however, IC 50 includes an optional receiver 77, such as an environmental monitoring receiver, that can evaluate the RF environment via an analysis of RF signal spectrum 203.
In particular, communication device 125 includes a plurality of transceivers 73 that wirelessly transceive data with a corresponding plurality of networks, such as networks 2, 4, 6, 8, etc. in accordance with a corresponding plurality of network protocols. Receiver 77 receives and processes received RF signals, over a broadband spectrum, such as RF signal spectrum 203 and generates environmental data in response thereto. Processing module 225 processes the environmental data and generates one or more control signals 141 in response thereto for adapting the transceivers 73 based on the environmental data.
In operation, receiver 77 analyzed an RF spectrum that encompasses the frequency bands used by each of the transceivers 73 including optional frequency bands that can be used by each of these transceivers. The environmental data can identify unused spectrum, used spectrum, desired channels, undesired channels, noise and interference, that can be used to adapt the transceivers 73 to more favorable conditions.
In one example, when conditions with respect to a particular frequency channel begin to deteriorate or otherwise a better frequency channel is found by receiver 77 for use by one of the plurality of transceivers 73, processing module 225 can generate control signals 141 and outbound data to coordinate with a remote station via control signaling and to switch the new frequency channel and to change the transceiver 73 to the new frequency channel. In another example, when communications with a particular network begin to deteriorate or otherwise a better network is found by receiver 77 for use by communication device 125, processing module 225 can generate control signals 141 and outbound data to coordinate a handoff to a new network or a new network device and either adapt a transceiver 73 to the new network or switch the transceiver 73 in use to a transceiver adapted for communication with the new network or network device. In addition, transceiver 73 can take on the function of receiver 77 during idle periods. In a further example, when communication conditions, such as noise and interference change for a particular transceiver, processing module 225 can generate control signals 141 to modify a transmission parameter and/or a receive parameter of the transceiver 73 to adapt to the change in conditions.
FIG. 7 is a graphical representation of a spectrum 210 in accordance with an embodiment of the present invention.

In particular, a communication system is shown wherein the management unit supplies cognitive transceiver configuration data 260 via a control channel to configure one or more cognitive radio transceivers of communication device 125. In this fashion, the cognitive radio transceiver can be configured for communication on different frequency channels, different frequency bands, with different networks, via different data rates and different protocols, to adapt to environmental conditions, device conditions and/or to otherwise be adapted with other transmit and receive characteristics.
For example, a logical control channel can be established between the communication device 125 and the management unit 200 via either a dedicated control channel transceiver, a transceiver operated in a control channel mode of operation, or a cognitive radio transceiver configured for operation as a control channel transceiver.

In this embodiment, a management unit 201 is used in place of management unit to communicates with communication device 125 via a direct or separate physical control channel, as discussed, for instance in conjunction with FIGS. 13-14.
FIG. 18 is a schematic block diagram of an embodiment of an RF transceiver 123′′ in accordance with the present invention. In particular, an RF transceiver 123′′ is shown that shares many common elements of the RF transceivers 123 and 123′ described in conjunction with FIGS. 5 and 15 that are referred to by common reference numerals and that can be used to implement transceivers 73, 73′ and 75. The RF transceiver 123′′ includes an RF transmitter 229, and an RF receiver 227. The RF receiver 227 includes a RF front end 140, a down conversion module 142 and a receiver processing module 144′. The RF transmitter 229 includes a transmitter processing module 146′, an up conversion module 148, and a radio transmitter front-end 150.
As shown, the receiver and transmitter are each coupled to an antenna through an antenna interface 171 and a diplexer (duplexer) 177, such as antenna interface 72 or 74, that couples the transmit signal 155 to the antenna to produce outbound RF signal 170 and couples inbound signal 152 to produce received signal 153. Alternatively, a transmit/receive switch can be used in place of diplexer 177. While a single antenna is represented, the receiver and transmitter may share a multiple antenna structure that includes two or more antennas. In another embodiment, the receiver and transmitter may share a multiple input multiple output (MIMO) antenna structure, diversity antenna structure, phased array or other controllable antenna structure that includes a plurality of antennas. Each of these antennas may be fixed, programmable, and antenna array or other antenna configuration.
In operation, the transmitter receives outbound realtime data 162 from other portions of its a host device, such as a communication application executed by processing module 225 or other source via the transmitter processing module 146′. The transmitter processing module 146′ processes the outbound data 162 in accordance with a particular wireless communication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce baseband or low intermediate frequency (IF) transmit (TX) signals 164 that contain outbound data 162. The baseband or low IF TX signals 164 may be digital baseband signals (e.g., have a zero IF) or digital low IF signals, where the low IF typically will be in a frequency range of one hundred kilohertz to a few megahertz. Note that the processing performed by the transmitter processing module 146′ can include, but is not limited to, scrambling, encoding, puncturing, mapping, modulation, and/or digital baseband to IF conversion.
The up conversion module 148 includes a digital-to-analog conversion (DAC) module, a filtering and/or gain module, and a mixing section. The DAC module converts the baseband or low IF TX signals 164 from the digital domain to the analog domain. The filtering and/or gain module filters and/or adjusts the gain of the analog signals prior to providing it to the mixing section. The mixing section converts the analog baseband or low IF signals into up-converted signals 166 based on a transmitter local oscillation.
The radio transmitter front end 150 includes a power amplifier and may also include a transmit filter module. The power amplifier amplifies the up-converted signals 166 to produce outbound RF signals 170, which may be filtered by the transmitter filter module, if included. The antenna structure transmits the outbound RF signals 170 to a targeted device such as a RF tag, base station, an access point and/or another wireless communication device via an antenna interface 171 coupled to an antenna that provides impedance matching and optional bandpass filtration.
The receiver receives inbound RF signals 152 via the antenna and off-chip antenna interface 171 that operates to process the inbound RF signal 152 into received signal 153 for the receiver front-end 140. In general, antenna interface 171 provides impedance matching of antenna to the RF front-end 140, optional bandpass filtration of the inbound RF signal 152 and optionally controls the configuration of the antenna in response to one or more control signals 141 generated by processing module 225.
The down conversion module 142 includes a mixing section, an analog to digital conversion (ADC) module, and may also include a filtering and/or gain module. The mixing section converts the desired RF signal 154 into a down converted signal 156 that is based on a receiver local oscillation, such as an analog baseband or low IF signal. The ADC module converts the analog baseband or low IF signal into a digital baseband or low IF signal. The filtering and/or gain module high pass and/or low pass filters the digital baseband or low IF signal to produce a baseband or low IF signal 156. Note that the ordering of the ADC module and filtering and/or gain module may be switched, such that the filtering and/or gain module is an analog module.
The receiver processing module 144′ processes the baseband or low IF signal 156 in accordance with a particular wireless communication standard (e.g., IEEE 802.11, Bluetooth, RFID, GSM, CDMA, et cetera) to produce inbound data 160. The processing performed by the receiver processing module 144′ includes, but is not limited to, digital intermediate frequency to baseband conversion, demodulation, demapping, depuncturing, decoding, and/or descrambling.
In an embodiment of the present invention, the RF transceiver 123′′ can be configured as a control channel transceiver to receive inbound data 160 that includes cognitive transceiver configuration data 260. The RF transceiver 123′′ can be configured as a control channel transceiver in a default mode of operation and then reconfigure itself based on the cognitive transceiver configuration data 260 received via either a physical or logical control channel established with management unit 200 or 201. Then, for example, when communication device 125 completes the task assigned to it in its reconfigured state, the RF transceiver 123′′ can reconfigure itself again to revert back to operation as a control channel transceiver.
The processing module 225 receives the cognitive transceiver configuration data 260 and generates one or more control signals 141 to configure or adapt the RF transceiver 123′′ in response thereto. Like the processing module 225 of RF transceiver 123′, processing module 225 generates control signals 141 to modify the transmit and/or receiver parameters of the RF transceiver 125 such as protocol parameters, data rates, modulation types and other data parameters used by receiver processing module 144′ and transmitter processing module 146′, frequency bands, channels and bandwidths, filter settings, gains, power levels, ADC and DAC parameters, and other parameters used by RF front-end 140, radio transmitter front-end 150, down conversion module 142 and up conversion module 148, as well as antenna configurations used by antenna interface 171 to set the beam pattern, gain, polarization, frequency band or other antenna configuration of the antenna.
For example, the cognitive transceiver configuration data 260 can include receiver frequency band configuration data for configuring the frequency band of the receiver front-end 140 via adjustment of a local oscillator frequency, filter bandwidth, etc, via control signals 140. The cognitive transceiver configuration data 260 can include transmitter frequency band configuration data for configuring the frequency band of the transmitter front end via adjustment of a local oscillator frequency, filter bandwidth, etc. The cognitive transceiver configuration data 260 can include baseband processing configuration data for configuring at least one baseband processing parameter of the receiver baseband processing module 144′ such as a particular modulation scheme, protocol, data rate, etc. The cognitive transceiver configuration data 260 can include baseband processing configuration data for configuring at least one baseband processing parameter of the transmitter baseband processing module 146′ such as a particular modulation scheme, protocol, data rate, etc.
The control signals 141 can be analog signals, digital signals, discrete-time signals of other signals that control the modules of RF transceiver 123′′ to adapt to communication via different networks. In this fashion, such a cognitive RF transceiver 123′′ can be configured to operate as either a Bluetooth transceiver, a GSM transceiver or a 802.11g transceiver based on the generation of the control signals 141 to implement the corresponding transmit and receive characteristics.
In a further mode of operation, the receiver processing module 144′ includes a receiver application memory 240 that stores a receiver application that is executed by the receiver processing module to perform the functionality of this receiver processing module 144′. In a default mode of operation the receiver application memory can store a default receiver application that causes the receiver processing module to operate in a particular configuration—such as a GSM receiver, a Bluetooth receiver, a CDMA receiver, a WIMAX receiver, and UWB receiver, a 802.11 receiver or as a control channel receiver, etc. The cognitive transceiver configuration data 260 can includes other baseband processing application data that can be received and stored in receiver application memory 240 and for execution by the receiver baseband processing module 144′ in a new configuration. For example, while operating as a control channel receiver, the RF receiver 227 can receive cognitive transceiver configuration data 260 that includes baseband processing application data with a new receiver application, for example a GSM receiver application, that is stored in receiver application memory 240 and executed by the receiver baseband processing module 144′ as part of a reconfiguration of the RF receiver 227 by processing module 225 as a GSM receiver.
In a similar fashion, the transmitter processing module 146′ includes a transmitter application memory 241 that stores a transmitter application that is executed by the transmitter processing module to perform the functionality of the transmitter processing module 146′. In a default mode of operation, the transmitter application memory can store a default transmitter application that causes the transmitter processing module to operate in a particular configuration—such as a GSM transmitter, a Bluetooth transmitter, a CDMA transmitter, a WIMAX transmitter, and UWB transmitter, a 802.11 transmitter or as a control channel transmitter, etc. The cognitive transceiver configuration data 260 can includes other baseband processing application data that can be received and stored in transmitter application memory 241 and for execution by the transmitter baseband processing module 146′ in a new configuration. For example, while operating as a control channel transceiver, the RF transceiver 123′′ can receive cognitive transceiver configuration data 260 that includes baseband processing application data with a new transmitter application, for example a GSM transmitter application, that is stored in transmitter application memory 241 and executed by the transmitter baseband processing module 146′ as part of a reconfiguration of the RF transmitter 229 by processing module 225 as a GSM transmitter.
