## Background
FIELD
The technical field relates to wireless communications. More particularly, the technical field relates to cognitive radio systems and methods employing software defined radio techniques to control and configure multiradio hardware in wireless communications.
BACKGROUND
Multiradio mobile devices typically include several different wireless subsystems that enable the use of diverse mobile services, such as the communication of voice, data, and images over diverse wireless networks. Examples of such diverse wireless networks include mobile telephony networks (e.g., Universal Mobile Telecommunications System (UMTS), Global System for Mobile Communication (GSM)), wireless local area networks (WLANs) and WiFi networks, and piconets (e.g., Bluetooth). An example multiradio device may have one radio for voice (or combined voice/data) service over a traditional cellular network and another radio for data communications over another network (e.g., WLAN). A multiradio device may have a WLAN radio for communication with a WLAN access point, a Bluetooth radio for communication with a Bluetooth enabled printer or headset, and a traditional voice service over a cellular telephone radio. A multiradio device may have a GSM radio and a digital video broadcast for handhelds (DVB-H) radio. A multiradio device may have more than one radio for communicating over different cellular telephone networks, such as a mobile telephone having two cellular radios for use with different types of networks in different countries.
Software Defined Radio (SDR) is typically a multiradio mobile device that is controlled by embedded control software. Some of the hardware components of a multiradio device may have their characteristics adjusted by SDR control software. The tuning capabilities in an example SDR may include RF band, RF bandwidth and channel bandwidth. Also, performance related parameters, such as gain and output power affecting for example noise and linearity may be tuned by control software making adjustments to hardware components to accommodate different wireless protocols and different radio conditions.
Cognitive radio is an intelligent wireless communication system that can be based on software-defined radios, which monitors the environment and adapts to variations in input signals, to improve the reliability of communication and the efficient use of the radio spectrum. When a user requests a task, such as a voice call, a data download, location tracking etc., the cognitive radio may aid the selection of the most suitable technology, such as GSM, WLAN, Bluetooth, or the like. Cognitive radio may more efficiently use the radio spectrum because a mobile device may scan the environment, determine the best or preferred frequency band and transmission standard, and indicate its preferences by signaling other cognitive radio devices with its preferred transmit power, channel equalization and coding scheme.

It is not uncommon in these days of ubiquitous wireless communications, to find an area having such a diverse ambient radio frequency environment. When an application a requests communication services from the wireless device 100, the example embodiments gather information about ambient wireless communication protocols, select an appropriate protocol for the requested communication, and configure the multiradio hardware components in the wireless device 100 for optimum performance in the requested communications session. The example embodiments can handle a requested communications service that involves two or more concurrent sessions using two or more communications protocols, such as downloading a file over a GSM cellular telephone network and transferring the downloaded file via a Bluetooth link to a personal computer. The example embodiments select communication protocols that can be run concurrently for the requested communications and configure the multiradio hardware components in the wireless device 100 to handle the two or more concurrent sessions.
FIG. 1B illustrates an example functional block diagram and an example circuit diagram of the wireless device 100 organized into three sections: the multiradio baseband processing section 120, the multichannel radio frequency (RF) software defined radio (SDR) application-specific integrated circuit (ASIC) section 122, and the RF front-end section 124. The ASIC is an integrated circuit customized to perform the functions of the multichannel radio frequency software defined radio.

The hardware accelerators 125 are hardware processors that have direct access to the memory and can handle extremely high bandwidth through parallel transactions to multiple buffers. They perform computationally intensive software code faster than a CPU executing software instructions, in applications such as high-speed packet processing and motion estimation in MPEG2. The baseband processing section 120 may also include interface circuits to interface with a key pad, display, optional microphone, speakers, ear pieces, and camera or other imaging devices, etc. The CPU processors 121 are programmed with computer program instructions stored in the memory, RAM 126 and/or ROM 128, to operate in accordance with the example processes depicted in the flow diagrams 200, 200′ and 200′′ of FIGS. 2A, 2B, and 2C, respectively. The memory, RAM 126 and/or ROM 128 in the multiradio baseband processing section 120, also stores an example cognitive platform control (CPC) stack 300 and the hardware manager 7 shown in FIGS. 3A and 3B.
FIG. 1D illustrates an example circuit diagram of the multiradio components in the multichannel RF SDR ASIC section 122 of the wireless device 100. Example multiradio components in the multichannel RF SDR ASIC section 122 include ASIC RF front-end paths 2A to 2L connected to multiplexers 150A to 150G and baseband paths 1A to 1H connected to lines 129 from the multiradio baseband processing section 120. ASIC RF front-end paths 2A to 2G are receive paths and include variable amplifiers such as 142A and mixers such as 141A to remove the RF carrier frequency from the received signal by mixing it with a reference signal from a selected one of the phase locked loop circuits 152A, 152B, 152C, or 152D, selected with the multiplexer 146A, as shown in FIG. 1H. The multiplexer 146C selectively steers the down-converted signal to one of the baseband paths 1A to 1D. Baseband paths 1A to 1D are receive paths and include RF filters such as 131A, analog-to-digital converters such as 132A, and digital filters such as 133A. Each of the amplifiers, filters, multiplexers, and analog-to-digital converters may have its characteristics selectively adjusted by the hardware abstraction layer (HAL) 0 and the protocol level hardware control 1 of the cognitive platform control stack 300 in the multiradio baseband processing section 120.

Each of the amplifiers, filters, multiplexers, and digital-to-analog converters may have its characteristics selectively adjusted by the hardware abstraction layer 0 and the protocol level hardware control 1 of the cognitive platform control stack 300 in the multiradio baseband processing section 120.
FIG. 1E illustrates an example circuit diagram of the multiradio components in the RF front-end section 124 of the wireless device 100.

The hardware manager 7 in the RAM 126 and/or ROM 128 of the wireless communications device is configured to receive information about ambient wireless communication protocols from the connection manager 304 and receive from applications 303 a request for communication services and to provide options for possible communication protocols to satisfy the request. The connection manager 304, an example functional block diagram of which is shown in FIG. 3C, continuously or periodically scans for ambient wireless communication signals over a wide RF band, e.g., an available spectrum from 1900 to 4000 MHz. The connection manager 304 includes a database of the carrier frequency, modulation type, timing, and format characteristics of a plurality of widely used wireless communication protocols. The connection manager 304 extracts the characteristics of received ambient wireless communication signals, identifies the ambient protocols, and compiles a list of the ambient protocols that it updates as the wireless device 100 moves from one location to another.
FIG. 3D illustrates an example functional block diagram of the hardware manager 7. The hardware manager 7 receives one or more requests for communication services, which may be received from another wireless device or may originate in an application running on the device 100. The hardware manager 7 receives the list of the ambient protocols from the connection manager 304. The hardware manager 7 select one or more possible communication protocols that fit the requests for communication services. The hardware manager 7 provides requests for one or more possible communication protocols to the cognitive hardware engine 6, to satisfy the requests for communication services. Later, the hardware manager 7 receives from the cognitive hardware engine 6 a recommendation for one or more of the protocols, which the hardware manager 7 confirms.
FIG. 3E illustrates an example functional block diagram of the cognitive hardware engine 6. The cognitive hardware engine 6 searches for one or more possible hardware configurations to satisfy the requests, in a database of hardware configuration path models of generic configurable and dedicated components for a variety of protocols. The cognitive hardware engine 6 receives hardware information from multiradio components in the device. The cognitive hardware engine 6 generates descriptions of one or more possible connected signal paths of the multiradio components to implement the one or more possible protocol options. The descriptions are output to the resource performance estimator 5. The cognitive hardware engine 6 receives a report of the lowest cost solutions from the resource allocator 3, which it forwards as a recommendation of one or more protocols to the hardware manager 7.
The cognitive hardware engine 6 in the RAM 126 and/or ROM 128 of the wireless communications device is configured to obtain hardware information from multiradio components in the multi-channel RF SDR ASIC 122 and RF front-end 124 of the device and to receive from the hardware manager 7, the application request and the options for possible protocols concerning the request. The cognitive hardware engine 6 is further configured to generate descriptions of one or more possible connected signal paths of the multiradio components to implement the one or more suggested possible protocols and request one or more performance estimates of the one or more possible connected signal paths of the multiradio components.
The cognitive hardware engine 6 consists of two sublayers, upper layer and lower layer. The functionality of the upper layer is to function as a recommendation engine for hardware manager 7. The cognitive hardware engine 6 possesses information on possible spectrum allocations and a database of generic paths of generic components for a variety of protocols. The functionality of the lower layer is as a hardware configuration engine that knows all possible configurations and their key properties (RF band, baseband bandwidth, dynamic range, baseband capacity) of the multiradio components in the multi-channel RF SDR ASIC 122 and RF front-end 124. The recommendation is based on the processes performed by the resource performance estimation layer 5, the multiradio timing 4, the resource allocation 3. The task that cognitive hardware engine 6 performs is, for example “Ask resource allocation layer 3 to provide resources for tasks”. In addition, cognitive hardware engine 6 communicates with the hardware abstraction layer 0 to get information on what kind of multiradio components are in the multi-channel RF SDR ASIC 122 and RF front-end 124. The hardware abstraction layer 0 abstracts the RF information from the application. This layer has precise information on the configuration possibilities, configuration times, power consumption estimates, performance (NF, DR, Gain, Band, Bandwidth) and maps the functions to hardware registers.
The resource performance estimator 5 in the RAM 126 and/or ROM 128 of the wireless communications device is configured to receive the requests for performance estimates from the cognitive hardware engine 6 and to provide performance estimates for the possible connected signal paths of the multiradio components in the multi-channel RF SDR ASIC 122 and RF front-end 124 to implement the suggested possible protocols. The resource performance estimator 5 functions as general performance analyzer and estimator to monitor events, for example missed commands, and it estimates resource usage. The resource performance estimator 5 conveys the collected information to cognitive hardware engine 6 for further handling.
FIG. 3F illustrates an example functional block diagram of the resource allocator 3. The resource allocator 3 in the RAM 126 and/or ROM 128 of the of the wireless communications device is configured to receive from the resource performance estimator 5, the performance estimates for possible connected signal paths of the multiradio components. The resource allocator 3 proposes to the multiradio timing module 4 different resource options for signal paths and requests whether resource usage is possible in the time domain. The multiradio timing module 4 provides answers to these proposals until proposed resource usages are found that are available and enable concurrent operation of the signal paths that they form. The multiradio timing module 4 indicates the identity of good resource options for paths that can run concurrently. The resource allocator 3 provides to the cognitive hardware engine 6 an allocation of the multiradio components for a selected one or more signal paths in the multi-channel RF SDR ASIC 122 and RF front-end 124 for selected one or more of the protocol options. The resource allocator 3 dynamically configures the resource allocation for each protocol option, preferably using lowest cost path for the tasks, based on algorithms and data from the memory. The lowest cost path algorithms use various parameters, for example prioritization list, time, and power consumption, as basis for their decisions.
The hardware manager 7 is further configured to receive from the cognitive hardware engine, information on the selected one or more of the protocol options and further configured to approve configuring the selected one or more of the possible connected signal paths in the multiradio components to implement the selected one or more of the protocol options on the multiradio components in the multi-channel RF SDR ASIC 122 and RF front-end 124. The hardware manager 7 is configured to confirm to the cognitive hardware engine 6, the allocation of the multiradio components 122 and 124 for the selected protocol. When the one or more selected protocol options have been confirmed by the hardware manager 7, the hardware manager 7 passes the identity of the one or more selected protocol options to the connection manager 304. The connection manager 304 enables the selected protocol stacks (protocol_1, protocol_2, protocol_3, and/or protocol_4 of FIG. 3B) to begin sending and receiving packets through the configured, selected signal paths in the multiradio components.
The cognitive hardware engine 6 is further configured to grant permission for the allocation of the multiradio components 122 and 124 for the selected protocol options.
The resource allocator 3 is further configured to receive from the cognitive hardware engine 6 the grant of permission the allocation of the multiradio components 122 and 124 for the selected protocol options and to generate a command to use the allocation of the multiradio components 122 and 124.
A performance adjuster 2 in the wireless communications device is configured to receive the command from the resource allocator 3 and to make local adjustments in the allocated multiradio components 122 and 124 to optimize performance.
The performance adjuster 2 performs local adjustments in the reserved resources/paths in order to optimize the performance, for example to minimize power consumption by re-partitioning gains of the components in the paths.
A protocol level hardware control 1 in the wireless communications device is configured to receive the command from the resource allocator 3 and to latch hardware control based on the commands for the allocated multiradio components 122 and 124. The protocol level hardware control 1 latches the hardware control based on protocol commands for the allocated resource.
The allocated multiradio components 122 and 124 are configured to receive the latched hardware control and to implement the selected protocol options to carry out the requested for communication services. Software configurable radio frequency components are described, for example, in the copending published patent application US 2008/0293445 assigned to Nokia Corporation and incorporated herein by reference.
The hardware manager 7 is further configured to receive from applications 303 a plurality of requests for communication services and to provide options for possible communication protocols to satisfy the plurality of requests.
FIG. 3G illustrates an example functional block diagram of the multiradio timing module 4. A multiradio timing module 4 in the wireless communications device is configured to receive from the resource allocator 3 different resource options for signal paths and receive a request to determine whether resource usage is possible for the possible signal paths for protocol options that can be implemented by a plurality of allocations of the multiradio components 122 and 124 to satisfy the plurality of respective requests. The multiradio timing module 4 determines whether the plurality of selected protocol options can run concurrently and whether resource usage is possible and it provides the resulting determination to the resource allocator 3. The multiradio timing module 4 determines the timing characteristics of each of the plurality of selected protocol options from timing allocation tables in the respective MAC layers of the protocols, as described in the copending published patent application US 2008/0002623 assigned to Nokia Corporation and incorporated herein by reference. The multiradio timing module 4 converts each protocol's system time to a common multiradio reference time, as described in the copending published patent application US 2008/0004070 assigned to Nokia Corporation and incorporated herein by reference. The multiradio timing module 4 performs a conventional RF circuit simulation of the operation of each of the signal paths in carrying out the respective protocol options, based on the common multiradio reference time. The multiradio timing module 4 simulates the operation of a first signal path for a first protocol option in common multiradio reference time, simulates the operation of a second signal path for a second protocol option in common multiradio reference time, and determines if the first and second signal paths can run concurrently. The multiradio timing module 4 repeats simulations and determinations in this manner for all combinations of the possible signal paths and the protocol options and identifies those possible signal paths that can run concurrently for the protocol options. The multiradio timing module 4 dynamically keeps track of the possible time scale allocations on a protocol level and provides the information as to whether certain protocols can run concurrently in the same platform. The multiradio timing module 4 then reports to the resource allocator 3 the identities of the possible signal paths that can run concurrently for protocol options. If two or more of the plurality of protocol options cannot run concurrently, then the multiradio timing module 4 requests the hardware manager 7 to determine whether to skip at least one of the plurality of protocol options.
The protocol level hardware control 1 is further configured to receive commands from the resource allocator 3 and to latch hardware control based on the commands for the plurality of allocations of multiradio components 122 and 124 connected over the plurality of respective signal paths for the plurality of respective selected protocols.
The allocated multiradio components 122 and 124 are further configured to receive the latched hardware control and to implement the plurality of respective selected protocols to carry out the plurality of respective requests for communication services.
FIG. 4 illustrates an example process flow diagram processing an example communications request using the multiradio RF platform control method of FIG. 3B. Initially, the hardware manager layer 7 in the wireless device 100 obtains information about ambient wireless communication protocols. Also, the cognitive hardware engine layer 6 gathers the hardware configurations and key properties in the wireless device 100 from the RF Hardware Abstraction Layer 0.
Then an example communications request is received by the hardware manager layer 7 in the wireless device 100 for an Internet connection. In response, the hardware manager layer 7 provides a recommendation of protocols X1, X2, and X4 to the cognitive hardware engine layer 6. The cognitive hardware engine layer 6 generates descriptions of one or more possible connected signal paths of the multiradio components to implement the one or more suggested possible protocols and requests one or more performance estimates of the one or more possible connected signal paths of the multiradio components from the resource performance estimation layer 5. The resource performance estimation layer 5 provides to the resource allocation layer 3, performance estimates for the possible connected signal paths of the multiradio components to implement the suggested possible protocols. The resource allocation layer 3 then asks the multiradio timing layer 4 if any of the possible connected signal paths can run concurrently with other existing signal paths. One or more signal paths are selected by the resource allocation layer 3 corresponding to one or more selected protocols and identified to the cognitive hardware engine layer 6. The cognitive hardware engine layer 6 then reports the recommendation of the selected signal paths for the identified protocols to the hardware manager layer 7.
The hardware manager layer 7 then confirms the selected signal paths for the identified protocols to the cognitive hardware engine layer 6. The cognitive hardware engine layer 6 grants permission for the selected signal paths for the identified protocols to the resource allocation layer 3. The resource allocation layer 3 commands the performance adjustment layer 2 to use the multiradio components to implement the selected signal paths for the identified protocols. The performance adjustment layer 2 obtains the current radio conditions from the protocol level hardware control layer 1. The performance adjustment layer 2 then instructs the RF Hardware Abstraction Layer 0 to use the multiradio components to implement the selected signal paths with specified values for the parameters of the components to accommodate the current radio conditions. The RF Hardware Abstraction Layer 0 then controls the multiradio components in the multi-channel RF SDR ASIC 122 and RF front-end 124 to form the selected signal paths for the identified protocols.
The granularity of the request by an application can vary. For example, the request may be “use WLAN access point having SSID XXX for the IP connection YYY” instead of using “use best connectivity to access service ZZZ in the internet”.
