Description

[0001] This application is a divisional application of Chinese invention patent application 201680071238.0 (PCT / US2016 / 067061), filed on December 15, 2016, entitled "Method and System for Processing Global Navigation Satellite System Signals". Technical Field

[0002] The embodiments described herein are for obtaining measurement results of signals acquired from a mobile transmitter. Background Technology

[0003] For example, satellite positioning systems (SPS) such as the Global Positioning System (GPS) have enabled navigation services for mobile handheld devices in outdoor environments. Mobile handheld devices can have navigation receivers capable of acquiring signals emitted by the SPS to obtain location information. Unfortunately, in some cases, noise and interference at the navigation receiver (such as from local man-made interference signals) can introduce false detections that lead to incorrect location estimates. Summary of the Invention

[0010] In another particular embodiment, a storage medium includes computer-readable instructions stored thereon, the computer-readable instructions being executable by a processor of a communication device to: encode an application content signal for transmission in a wireless transmission medium to provide symbolic content, the symbolic content including first symbols representing several portions of the application content signal; and generate a signal to selectively blank a receiver synchronized with at least a portion of the symbolic content.

[0011] In another embodiment, as described above, a communication apparatus includes: means for encoding application content signals for transmission in a wireless transmission medium to provide symbolic content, the symbolic content including first symbols representing a plurality of portions of the application content signals; means for up-converting the symbolic content into radio frequency signals for transmission in the wireless transmission medium; and means for selectively blanking a receiver synchronized with at least a portion of the symbolic content.

Furthermore, it should be understood that the particular features, structures, characteristics, and / or the like described can be combined in different ways in one or more embodiments and / or examples and are therefore within the scope of the established claims. Of course, generally, as has always been the case in the specification of the patent application, these and other issues may vary in the specific use case. In other words, throughout the patent application, the specific use case described and / or used provides useful guidance on reasonable inferences about what is to be drawn; however, similarly, "in this case" generally does not further limit itself and refers to the case of this patent application.

[0023] Wireless communication systems have come in various generations, including first-generation analog wireless telephone service (1G), second-generation (2G) digital wireless telephone service (including temporary 2.5G networks), and third-generation (3G) and fourth-generation (4G) high-speed data / Internet-enabled wireless services.

[0024] In recent years, Long Term Evolution (LTE) has been developed by the 3rd Generation Partnership Project (3GPP) as a radio access network technology for high-speed data and packet-based voice wireless communication in mobile phones and other mobile terminals. LTE has evolved from the Global System for Mobile Communications (GSM) and from GSM derivatives such as GSM Evolution Enhanced Data Rate (EDGE), Universal Mobile Telecommunications System (UMTS), and High Speed ​​Packet Access (HSPA).

[0025] Uplink carrier aggregation (ULCA) is a specific technique for improving upload speeds in LTE-capable mobile devices, which may involve increasing modulation complexity and throughput from 16-QAM to 64-QAM. However, these improved uplink bandwidth maps cannot be reliably achieved in areas with poor coverage. In certain implementations of LTE-capable mobile devices, using frequency division duplex (FDD) to communicate with base stations in the wireless communication link allows for greater coverage.

[0026] Mobile devices with LTE capability may include navigation receivers, such as receivers capable of acquiring signals transmitted by spacecraft (SVs) in a Global Navigation Satellite System (GNSS). Unfortunately, uplink signal transmissions by LTE-enabled mobile devices over FDD links can introduce multi-tone interference (MTI) at the GNSS receiver. Specifically, transmissions of certain content in the uplink portion of an FDD wireless communication link can cause spectral components in the GNSS receiver's receiving band to interfere, leading to false detections at the GNSS receiver. For example, transmissions of certain content in the uplink, such as demodulation reference signal (DMRS) symbols or sounding reference signal (SRS) symbols, can introduce MTI into the GNSS receiver. As explained below, such MTI can introduce evenly spaced frequencies.

[0027] According to one embodiment, a GNSS receiver on a mobile device can be selectively blanked in synchronization with a portion of the content in an uplink signal being transmitted by the mobile device. Selectively blanking the GNSS receiver during the transmission of specific content in the uplink signal enables simultaneous use of the GNSS receiver with the transmission of the uplink signal, while reducing or eliminating artificial interference effects from the transmission of certain content (e.g., SRS or DMRS symbols) in the uplink signal.

[0028] Figure 1 This is a system diagram illustrating certain features of a system containing a mobile device (MD) 100 according to an embodiment. The MD 100 can receive or acquire Satellite Positioning System (SPS) signals 159 from an SPS satellite 160. In some embodiments, the SPS satellite 160, including the transmitter, may originate from a Global Navigation Satellite System (GNSS), such as GPS or Galileo. In other embodiments, the SPS satellite may originate from multiple GNSSs, such as (but not limited to) GPS, Galileo, GLONASS, or BeiDou (Compass) satellite systems. In other embodiments, the SPS satellite may originate from any of several Regional Navigation Satellite Systems (RNSSs), such as WAAS, EGNOS, QZSS (to name just a few).

[0029] Additionally, MD 100 can transmit radio signals to and / or receive radio signals from a wireless communication network. In one example, MD 100 can communicate with a cellular communication network by transmitting or receiving radio signals from base transceiver 110 via wireless communication link 123. Similarly, MD 100 can transmit or receive radio signals from local transceiver 115 via wireless communication link 125.

[0030] In a particular implementation, local transceiver 115 may be configured to communicate with MD 100 over a shorter distance via wireless communication link 123 than that achieved by base transceiver 110 via wireless communication link 123. For example, local transceiver 115 may be located in an indoor environment. Local transceiver 115 may provide access to a wireless local area network (WLAN, such as an IEEE standard 802.11 network) or a wireless personal area network (WPAN, such as a Bluetooth network). In another example implementation, local transceiver 115 may include a femtocell transceiver capable of facilitating communication on link 125 according to cellular communication protocols. However, it should be understood that these are merely examples of networks that can communicate with MD via wireless links, and / or the claimed subject matter is not limited in this respect.

[0031] In a particular embodiment, base transceiver 110 and / or local transceiver 115 can communicate with servers 140, 150, and / or 155 via link 145 through network 130. Here, network 130 may include any combination of wired and / or wireless links. In a particular embodiment, network 130 may include Internet Protocol (IP) infrastructure capable of facilitating communication between MD 100 and servers 140, 150, or 155 via local transceiver 115 or base transceiver 110. In another embodiment, network 130 may include cellular communication network infrastructure, such as a base station controller or primary switching center, to facilitate mobile cellular communication with MD 100.

[0032] In certain embodiments, and / or as discussed below, MD 100 may have circuitry and / or processing resources capable of calculating the location and / or estimated position of MD 100. For example, MD 100 may calculate the location at least in part based on pseudorange measurements to four or more SPS satellites 160. Here, MD 100 may calculate the pseudorange measurements at least in part based on pseudo-noise code phase detection in signals 159 acquired from four or more SPS satellites 160. In certain embodiments, MD 100 may receive positioning assistance data from servers 140, 150, or 155 to assist in acquiring signals 159 transmitted by SPS satellites 160, including, for example, calendars, ephemeris data, Doppler search windows, and to name just a few.

[0033] As discussed above, in a particular embodiment, MD 100 can communicate with base transceiver 110 via an LTE-enabled FDD wireless communication link. Thus, when attempting to acquire the SPS signal 159 to perform a positioning operation, the uplink portion of the wireless communication link 123 can impart multi-frequency tone (MFT) artificial interference signals to the SPS receiver at MD 100. In a particular embodiment, MD 100 can blank the SPS receiver synchronously with the content being transmitted on the uplink portion of the wireless communication link 123 to avoid or mitigate MFT artificial interference effects.

[0034] Figure 2 This describes the transmission of specific content in the uplink signal of an FDD wireless communication link according to one embodiment. Here, the signal transmission is divided into several "time slots" according to time, during which a series of discrete symbols can be transmitted. In the fourth symbol period of time slots 0 and 1, demodulation reference symbols (DMRS) pilot symbols are transmitted, and physical uplink shared channel (PUSCH) symbols are transmitted in the first to third and fifth to seventh symbols of time slots 0 and 1. Figure 3 This illustrates another scenario where the DMRS pilot symbols are similarly transmitted in the fourth symbol period (shown as PUSCH RS) of time slots 0 and 1. As shown, additional content can be transmitted in the first two and last two subcarrier bands. As noted above according to one embodiment, the transmitter in... Figure 2 and 3 DMRS symbols transmitted in slots 0 and 1 of the FDD uplink can impart multi-tone artificial interference signals at an SPS receiver located in the same position as the transmitter (e.g., in a mobile phone). In one instance, multi-tone artificial interference may include a single tone at a specific frequency repeated at intervals that are integer multiples of a particular harmonic frequency (e.g., 1.0 kHz). It should be understood, however, that 1.0 kHz is merely an example of a specific harmonic interval for a tone in a multi-tone artificial interference signal, and the claimed target is not limited in this respect. As discussed above, the SPS receiver can be blanked during the transmission of the DMRS symbol to reduce or eliminate spectral interference that generates false detections of artificial interference signals at the SPS receiver.

[0035] In a particular implementation, a mobile device transmitting FDD uplink signals may have transceiver and / or modem devices to transmit on the uplink signals and process downlink signals. According to one embodiment, the transceiver and / or modem devices may generate a blanking signal to be applied to a terminal of an SPS receiver located in the same position to control the blanking of the SPS receiver during certain portions of the FDD uplink transmission. For example, the blanking signal may be synchronized with the transmission of specific content on the FDD uplink that could introduce the aforementioned multi-frequency tone artificial interference effects. Figure 4 As shown, in a particular embodiment, the transceiver device and / or modem device may generate a blanking signal synchronized with the transmission of specific content (e.g., DMRS symbols and / or SRS symbols) in the FDD uplink. The blanking signal may be applied to a terminal of the SPS receiver device to receive the blanking signal during the transmission of content that introduces multi-frequency audio interference.

[0036] According to one embodiment, a GNSS receiver (e.g., such as...) Figure 4 The band-related blanking (as described in the document) can be configured to enable / disable individual FDD-LTE bands for non-ULCA and ULCA scenarios, respectively. For example, for the LTE B2 non-ULCA scenario, LTE B2 can be configured to not be blanked because the B2 LTE band itself may not interfere with or obstruct GNSS receivers. In the B2 / B4 ULCA scenario, LTE B2 can be configured to be blanked because the B4 LTE band may interfere with or obstruct GNSS receivers. And in the B2 / B13 ULCA scenario, LTE B2 can be configured to not be blanked because B13 may not interfere with or obstruct GNSS receivers. However, it should be understood that these are merely examples of how bands in the FDD uplink can be blanked independently, and the claimed subject matter is not limited in this respect. Blanking in individual frequency bands for both non-ULCA and ULCA cases can be controlled independently based on lookup tables (e.g., for B2, different lookup table items for non-ULCA (single Tx), B2 / B4ULCA, B2 / B13 ULCA, etc.).

[0037] According to one embodiment, blanking can be configured to be enabled in a specific FDD-LTE band across multiple frequency bands in the uplink signal. In one embodiment, before the transmission of a DMRS or SRS symbol from the LTE transmit antenna begins, the modem software or firmware can control the assertion of the blanking terminal of the signal to the GNSS receiver with a specific lead time (e.g., 2.0 μsec). In another embodiment, after the transmission of a DMRS or SRS symbol, the modem software or hardware can assert the blanking terminal to indicate non-blanking for 2.0 μsec. However, it should be understood that these are merely examples of how the receiver can be controlled to blank in response to a specific content symbol, and the claimed subject matter is not limited in this respect.

[0038] Figure 5 This describes the spectrum of multi-frequency tone interference signals at a GNSS receiver caused by uplink transmissions in the FDD wireless communication link without blanking certain content (e.g., SRS or DMRS symbols). Without blanking, energy peaks 500 extending above 119.5 dB can introduce false detections at the SPS receiver. Selective blanking of the SPS receiver, synchronized with specific content transmitted in the FDD uplink, can largely eliminate energy peaks 500.

[0039] Figure 6 This is a schematic block diagram of a system according to one embodiment that transmits symbols in a wireless transmission medium via radio frequency (R / F) circuitry 614 and processes the signals at an SPS receiver 612 (e.g., on the same handheld device) very close to the R / F circuitry 614. In a particular embodiment, modem 600 may process application content 602 for transmission in uplink signals at the radio frequency (R / F) circuitry 614. Modem 600 may also provide control signals 610 to the SPS receiver 612 to selectively blank reception of signals received at the GNSS receiver 612 to mitigate artificial interference from the transmission of content at the R / F circuitry 614. Modem 600 may include a combination of hardware circuitry and firmware (e.g., for execution on a microprocessor or digital signal processor) to implement action or to process application content 602 for transmission by the R / F circuitry 614 and to generate control signals 610.

[0040] According to one embodiment, application content 602 may include digital content such as text of a text message, sampled audio / voice signals, digital images (e.g., video or still images), Internet Protocol packets, to name just a few. Application content 602 may be stored digitally (e.g., as bits representing one and zero) in memory or a buffer. While application content 603 may further exist in a specific encoded format (e.g., ASCII encoded text, vocoder or other audio encoded symbols, MPEG or JPEG encoded symbols), box 603 in modem 600 may provide a particular application content encoding to process application content 60 for transmission over a wireless transmission medium. In other embodiments, without departing from the claimed subject matter, one or more actions described as being performed at box 603 may be performed in an application processor.

[0041] Box 604 can further prepare the encoded application content for transmission over a wireless transmission medium (e.g., an LTE FDD uplink channel). For example, such as Figure 2 and 3 As described herein, block 604 may allocate the transmission of coded symbols containing application content to distribute transmission time slots (e.g., as PUSCH symbols) and interleave additional channel-specific symbols (including, for example, DMRS and SRS symbols). However, it should be understood that this is merely an example of how application content can be further processed for transmission in a wireless communication channel, and the claimed subject matter is not limited in this respect.

[0042] The encoded content generated by block 604 can be further processed in block 606 by, for example, further encoding the symbol content for up-conversion at R / F circuit 614. For instance, block 606 can further encode the symbol content for QPSK, CDMA, or QAM processing to generate a baseband signal. R / F circuit 614 can then up-convert the baseband signal into an R / F signal for transmission in a wireless communication medium (e.g., a signal in an LTE FDD uplink) using circuitry that performs, for example, digital-to-analog conversion, modulation, RF up-conversion, and power amplification.

[0043] According to one embodiment, block 604 can generate a signal comprising a sequence of symbols in digital form (e.g., expressed as a sequence of ones and zeros). Figure 2 and 3In a specific instance of the channel-coded content shown, this symbol sequence may include coded content symbols interleaved with channel-specific symbols such as DMRS or SRS symbols. According to one embodiment, block 608 may analyze the channel-coded content generated at block 604 to generate a control signal 610 to determine the timing and / or duration at which the SPS receiver 612 will blank. For example, block 604 may analyze a specific symbol pattern, such as analyzing a specific symbol or bit sequence allocated to a specific time slot for transmission in the uplink channel. In one embodiment, block 604 may insert / interleave DMRS and / or SRS symbols. Block 608 may detect the timing of DMRS and / or SRS symbols and predict / determine the timing of DMRS and / or SRS symbol transmission via an antenna connected to R / F circuitry 614. Control signal 610 may implement, as... Figure 4 The blanking signal shown is used to blank the SPS receiver 612 during the transmission of SRS and / or DMRS symbols by the R / F circuit 614. In a particular embodiment, the control signal 610 may include a voltage applied to a device pin, such as... Figure 4 As shown. In an alternative embodiment, the control signal can be asserted as a bi-state switch for the start of a signaling blanking cycle followed by the start of a non-blanking cycle. In another embodiment, control signal 610 can provide digital signals on a high-speed bus. However, it should be understood that these are merely examples of how control signal 610 can be implemented to achieve the blanking SPS receiver 612, and the claimed object is not limited in this respect.

[0044] Figure 7A and 7B This is a flowchart of the process used to blank the receiver in a way that synchronizes with the content of the transmitted signal. Figure 7A and 7B The action performed at the location can be, for example, by a mobile device (e.g., Figure 8 The mobile device 1100 shown or the access point may perform this action. However, it should be understood that these are only those that can be configured to perform this action. Figure 7A and 7BThe examples shown are examples of the structure of the actions, and the claimed object is not limited in this respect. At block 702, an uplink signal can be transmitted in a wireless communication link. In one particular embodiment, block 702 can transmit an uplink signal in an FDD wireless communication link (e.g., an LTE FDD uplink). In another particular embodiment, block 702 can transmit an uplink signal in a wireless local area network (WLAN) communication link or a wireless personal area network (WPAN) communication link or a combination thereof. In this context, "uplink signal" as used herein refers to a signal transmitted to a device in a wireless communication medium to enable access to a wireless communication service. For example, a mobile user equipment can transmit a message to a base station in an LTE network in an uplink signal. However, it should be understood that these are merely examples of uplink signals, and the claimed object is not limited in this respect. In this context, as used herein, "FDD wireless communication link" refers to an established wireless communication link that allows message transmission between first and second devices such that messages transmitted from the first device to the second device are transmitted in a first portion of the wireless spectrum, and messages transmitted from the second device to the first device are transmitted in a second portion of the wireless spectrum at frequencies not overlapping with the first portion of the wireless spectrum. In one example implementation, the uplink signal in the FDD wireless communication link transmits messages from the mobile user device to the base station in a spectrum that does not overlap with the spectrum used for transmitting messages from the base station to the mobile user device in the downlink signal. However, it should be understood that this is merely an example of an FDD wireless communication link, and the claimed subject matter is not limited in this respect.

[0045] Box 704 includes an SPS receiver that selectively blanks a portion of the content transmitted in the uplink at box 702. In this context, "SPS receiver" as used herein refers to a receiving device capable of processing at least a portion of a received signal transmitted by an SPS transmitter (e.g., SPS signal 159 transmitted by SPS satellite 160) to obtain information (e.g., code phase detection, carrier phase detection, system time, etc.). Additionally, in this context, "content" as used herein refers to a representation of a signal that will be stored or transmitted independently of any particular format used for transmission at a particular frequency or in a particular physical transmission or storage medium. It should be understood that content is not necessarily limited to application content. For example, content may include encoded application content combined with channel-specific symbols, including, for example, DMRS and SRS symbols interleaved with application content symbols (e.g., expressed as a series of ones and zeros for transmission in a time slot). In this context, as used herein, "blanking" of a receiver means that reception of one or more signals is suspended at the receiver device for a duration. In one example, blanking of the receiver may include suspending the electrical connection to the receiver device for a duration such that the reception of one or more signals is suspended during the blanking period. In a particular embodiment, the SPS receiver may blank for 72.0 μsec, covering the period of transmitting the DMRS symbol, and then not blank for the following 428.0 μsec for normal operation of the SPS receiver. Additionally, in this context, "selective blanking" as used herein refers to a process of controlling the receiver device in such a way as to suspend the processing of received signals. For example, the receiver device may be selectively blanked by, for instance, disconnecting the receiving circuitry from the received signal, removing power from at least a portion of the receiver device, attenuating / grounding the received signal (to name just a few examples). In one embodiment, the receiver device may be blanked in response to a voltage signal (e.g., control signal 610) applied to the input terminal of a switch to electrically disconnect the receiver device during the blanking period. In another embodiment, blacking out the receiver may include forcing the digital processing circuitry (e.g., analog-to-digital converter) in the receiver to provide 0.0V as an output signal during the blanking period. However, it should be understood that this is merely an example of how a blanking receiver device can be implemented, and the claimed subject matter is not limited in this respect.

[0046] Furthermore, in this context, blanking of a receiver "synchronized with a portion of the content," as mentioned herein, means that the reception blanks during the moment and / or period during which it is synchronized with the characteristics of the content being transmitted. Figure 6In the specific implementation examples described herein, SPS receiver 612 may be selectively blanked at least in part based on the timing of DMRS or SRS symbols detected in the symbol content generated at block 604. For example, SPS receiver 612 may be selectively blanked during intervals in which DMRS or SRS signals are transmitted via an antenna connected to R / F circuitry 614. In one example, as noted above, control signal 610 may include providing a blanking signal to SPS receiver 612 with a lead time (e.g., 2.0 μsec) before transmitting specific content (e.g., DMRS or SRS symbols or other content that imparts an artificial interference effect) via R / F circuitry 614. However, it should be understood that this is merely an example of how the blanking of the receiver can be synchronized with the content transmitted in the uplink signal, and the claimed subject matter is not limited in this respect.

[0047] In a particular implementation, block 704 may include selective blanking based at least in part on specific channels or frequency bands of the uplink signal. For example, block 704 may blank the SPS receiver without uplink transmission for ULCA LTE B2 / B4, but not for LTE B2 non-ULCA cases. Furthermore, block 704 may include selective blanking based on the transmit power applied by the transmitter for transmitting the uplink signal at block 702. Additionally, for multi-band SPS receivers (e.g., capable of handling any combination of GPS, GLONASS, BeiDou, or Galileo signals), block 704 may selectively blank some SPS bands without blanking others.

[0048] Figure 7B This is a flowchart of a process according to an alternative embodiment. Block 706 includes an encoded application content signal for transmission in a wireless communication medium to provide symbolic content. In this context, "application content signal" as used herein refers to an expression or representation of the content of an application (e.g., text, audio signals, image signals, etc.) that supports a specific format. "Symbolic content" as used herein includes discrete encoded expressions in a specific format that, if properly combined according to the format, represent all or part of the content to be transmitted in a wireless transmission medium. Figure 6 In an example, symbol content may include a sequence of symbols, such as those generated by box 604, which may contain coded symbols representing application content interleaved with channel control symbols. Therefore, it should be recognized that in this particular context, symbol content is not necessarily limited to coded symbols representing application content, but may also include channel control symbols, such as DMRS or SRS symbols. However, it should be understood that these are merely examples of symbol content, and the claimed subject matter is not limited in this respect.

[0049] Block 708 may include upconverting the symbol content generated at block 706 to an R / F frequency for transmission in a wireless transmission medium. In this context, "upconversion" as used herein refers to converting a signal to a specific format suitable for transmission in a transmission medium at a specific carrier frequency. For example, R / F circuitry 614 may modulate the signal at a specific carrier frequency based on a baseband signal from block 606, which is at least partially based on the symbol content generated by block 604. Block 710 then selectively blanks a receiver synchronized with a portion of the symbol content, as discussed above.

The general-purpose processor 1111 and / or the DSP 1112 can execute instructions to perform the combined instructions described above. Figure 6 , 7A One or more aspects of the process discussed in 7B.

[0055] Figure 8 The document also shows that the user interface 1135 may include any of a number of devices, such as a speaker, microphone, display device, vibration device, keyboard, touchscreen, to name just a few. In a particular embodiment, the user interface 1135 enables a user to interact with one or more applications hosted on the mobile device 1100. For example, the device of the user interface 1135 may store analog or digital signals on memory 1140 for further processing by the DSP 1112 or general-purpose / application processor 1111 in response to actions from the user. Similarly, an application hosted on the mobile device 1100 may store analog or digital signals on memory 1140 to present output signals to the user. In another embodiment, the mobile device 1100 may optionally include dedicated audio input / output (I / O) devices 1170, including, for example, dedicated speakers, microphones, digital-to-analog circuitry, analog-to-digital circuitry, amplifiers, and / or gain control. However, it should be understood that this is merely one example of how audio I / O can be implemented in a mobile device, and the claimed subject matter is not limited in this respect. In another embodiment, the mobile device 1100 may include a touch sensor 1162 that is responsive to touch or pressure on a keyboard or touchscreen device.

The environmental sensors of mobile device 1100 may include, for example, temperature sensors, barometric pressure sensors, ambient light sensors, camera imagers, and microphones, to name just a few. Sensor 1160 may generate analog or digital signals that can be stored in memory 1140 and processed by a DPS or general-purpose / application processor 1111, which supports one or more applications, such as applications for positioning or navigation operations.

[0058] In a particular embodiment, mobile device 1100 may include a dedicated modem processor 1166 capable of performing baseband processing on signals received and down-converted at wireless transceiver 1121. Similarly, dedicated modem processor 1166 may perform baseband processing on signals to be up-converted for transmission by wireless transceiver 1121. In exemplary embodiments, modem processor 1166 may have one or more of the features of modem 600 discussed above. In alternative embodiments, as an alternative to having a dedicated modem processor, baseband processing may be performed by a general-purpose processor or DSP (e.g., general-purpose / application processor 1111 or DSP 1112). However, it should be understood that these are merely examples of structures capable of performing baseband processing, and the claimed subject matter is not limited in this respect.

[0063] As used herein, the term "mobile device" refers to a device that may have a changing location from time to time. Changes in location may include changes in direction, distance, orientation, etc., as examples. In specific examples, a mobile device may include a cellular telephone, a wireless communication device, a user equipment, a laptop computer, other personal communication system (PCS) devices, a personal digital assistant (PDA), a personal audio device (PAD), a portable navigation device, or other portable communication device. A mobile device may also include a processor and / or computing platform adapted to perform functions controlled by machine-readable instructions.

[0064] The methods described herein may be implemented using various means depending on the application for a particular instance. For example, these methods may be implemented in hardware, firmware, software, or a combination thereof. In, for example, hardware implementations, the processing unit may be implemented within one or more application-specific integrated circuits (“ASICs”), digital signal processors (“DSPs”), digital signal processing devices (“DSPDs”), programmable logic devices (“PLDs”), field-programmable gate arrays (“FPGAs”), processors, controllers, microcontrollers, microprocessors, electronic devices, other device units designed to perform the functions described herein, or combinations thereof.

[0065] Algorithm descriptions and / or symbolic representations are examples of techniques used by those skilled in signal processing and / or related fields to communicate the substance of their work to others skilled in the field. An algorithm herein and generally is considered a self-consistent sequence of operations and / or similar signal processing that produces a desired result. In this context, operations and / or processing involve the physical manipulation of physical quantities. Often, but not necessarily, these quantities may take the form of electrical and / or magnetic signals and / or states that can be stored, transmitted, combined, compared, processed, or otherwise manipulated as electronic signals and / or states representing various forms of content (e.g., signal measurements, text, images, video, audio, etc.). Primarily for common use, it has proven sometimes convenient to refer to such physical signals and / or physical states as bits, bytes, values, elements, symbols, characters, terms, numbers, digits, expressions, messages, fields, identifier frames, measurements, content, and / or the like. However, it should be understood that all such terms or similar terms should be associated with the appropriate physical quantity and are merely convenient notations. Unless otherwise explicitly stated, as is apparent from the foregoing, it should be understood that throughout this specification, the use of terms such as “processing,” “operation,” “calculation,” “determining,” “establishing,” “acquiring,” “identifying,” “selecting,” “generating,” and / or the like can refer to the actions and / or processing procedures of a particular device, such as a dedicated computer and / or a similar dedicated computing and / or network device. Therefore, in the context of this specification, a dedicated computer and / or a similar dedicated computing and / or network device is capable of processing, manipulating, and / or transforming signals and / or states of physical electrical and / or magnetic quantities typically represented as memory, registers, and / or other storage devices, transmitting devices, and / or display devices of a dedicated computer and / or a similar dedicated computing and / or network device. In the context of this particular patent application, as mentioned, the term “particular device” can include general-purpose computing and / or network devices, such as a general-purpose computer (once it is programmed to perform a specific function according to instructions from program software).

[0066] In some cases, the operation of a memory device (e.g., a change of state from binary one to binary zero, or from binary zero to binary one) may include transformations such as physical conversions. In the case of certain types of memory devices, such physical conversions may include physically transforming an item into a different state or object. For example, but not limited to, for some types of memory devices, a change of state may involve accumulating and / or storing charge or releasing stored charge. Similarly, in other memory devices, a change of state may include physical changes, such as changes in magnetic orientation and / or physical alterations and / or changes in molecular structure, such as from a crystalline to an amorphous or from an amorphous to a crystalline state. In still other memory devices, for example, a change of physical state may involve quantum mechanical phenomena, such as the superposition, kinking, etc., of qubits. The foregoing is not intended to be an exhaustive list of all instances of transformations such as physical conversions that a change of state (from binary one to binary zero or from binary zero to binary one) in a memory device may include. Rather, the foregoing is intended to be illustrative.

[0067] The wireless communication technologies described herein can be combined with various wireless communication networks, such as wireless wide area networks (“WWAN”), wireless local area networks (“WLAN”), wireless personal area networks (WPAN), and so on. In this context, a “wireless communication network” includes multiple devices or nodes capable of communicating with each other via one or more wireless communication links. For example... Figure 1 and Figure 2As shown, 1, for example, a wireless communication network may include two or more devices from mobile devices 100a, 100b, 115a, and 115b. The terms "network" and "system" are used interchangeably herein. A WWAN may be a Code Division Multiple Access ("CDMA") network, a Time Division Multiple Access ("TDMA") network, a Frequency Division Multiple Access ("FDMA") network, an Orthogonal Frequency Division Multiple Access ("OFDMA") network, a Single Carrier Frequency Division Multiple Access ("SC-FDMA") network, or any combination thereof, etc. A CDMA network may implement one or more Radio Access Technologies ("RATs"), such as cdma2000, Wideband CDMA ("W-CDMA"), to name just a few. Here, cdma2000 may include technologies implemented according to the IS-95, IS-2000, and IS-856 standards. A TDMA network may implement the Global System for Mobile Communications ("GSM"), Digital Advanced Mobile Telephone Systems ("D-AMPS"), or some other RAT. GSM and W-CDMA are described in documents from an association called the 3rd Generation Partnership Project (3GPP). CDMA2000 is described in documents from an association called the 3rd Generation Partnership Project 2 (3GPP2). 3GPP and 3GPP2 documents are publicly available. In another respect, 4G Long Term Evolution (“LTE”) communication networks can also be implemented according to the claimed target. For example, WLAN may include IEEE 802.11x networks, and WPAN may include Bluetooth networks, IEEE 802.15x. The wireless communication implementations described herein can also be used in combination with any combination of WWAN, WLAN, or WPAN.

[0068] On the other hand, as previously mentioned, the wireless transmitter or access point may include a femtocell for extending cellular telephone service to businesses or homes. In this embodiment, for example, one or more mobile devices may communicate with the femtocell via a Code Division Multiple Access (“CDMA”) cellular communication protocol, and the femtocell may provide the mobile devices with access to a larger cellular telecommunications network via another broadband network (such as the Internet).

[0069] The techniques described herein can be used with SPS systems that include any of a number of GNSS systems and / or combinations of GNSS systems. Furthermore, these techniques can be used with positioning systems that utilize ground transmitters acting as “pseudo-satellites” or combinations of SV systems with these ground transmitters. The ground transmitter may be, for example, a ground-based transmitter that includes a broadcast PN code or other ranging code (e.g., similar to GPS or CDMA cellular signals). This transmitter may be assigned a unique PN code to allow identification by a remote receiver. The ground transmitter can be used, for example, to augment SPS systems in situations where SPS signals from orbital SVs may be unavailable, such as in tunnels, mines, buildings, urban canyons, or other enclosed areas. Another implementation of a pseudo-satellite is referred to as a radio beacon. As used herein, the term “SV” is intended to include ground transmitters that act as pseudo-satellites, pseudo-satellite equivalents, and possibly others. As used herein, the terms “SPS signal” and / or “SV signal” are intended to include SPS-like signals from ground transmitters that include ground transmitters acting as pseudo-satellites or pseudo-satellite equivalents.

[0070] Similarly, in this context, the terms "coupling," "connection," and / or similar terms are generally used. It should be understood that these terms are not intended to be synonyms. In practice, "connection" is generally used to indicate that two or more components (e.g.,) are in direct physical (including electrical) contact; while "coupling" is generally used to mean that two or more components may be in direct physical (including electrical) contact; however, "coupling" is also generally used to mean that two or more components are not necessarily in direct contact, but are able to cooperate and / or interact. The term "coupling" is also generally understood, for example, in this context, to mean an indirect connection.

[0071] As used herein, the terms “and,” “or,” “and / or,” and / or similar terms include multiple meanings, which are also assumed to be at least partly based on the specific context in which they are used. Generally, “or,” if used to relate a list (e.g., A, B, or C), implies A, B, and C (used here in an inclusive sense), and A, B, or C (used here in an exclusive sense). Additionally, the terms “one or more” and / or similar terms are used to describe any feature, structure, and / or characteristic in a singular form, and / or also to describe multiple features, structures, and / or characteristics and / or some other combination of features, structures, and / or characteristics. Similarly, the terms “based on” and / or similar terms are understood not to convey an exclusive set of factors, but rather to allow for the existence of additional factors that do not need to be explicitly described. Of course, for all the foregoing, the description of the content and / or the specific context of its use provides helpful guidance regarding the inferences to be made. It should be noted that the following description provides only one or more illustrative examples, and the subject matter claimed is not limited to these one or more examples; however, the description and / or use in a particular context provide helpful guidance on the inferences to be made.

[0072] In this context, the term "network device" refers to any device capable of communicating via and / or as part of a network, and may include computing devices. While network devices may be able to send and / or receive signals (e.g., signal packets and / or frames), for example via wired and / or wireless networks, they may also be able to perform arithmetic and / or logical operations, process and / or store signals, for example as physical memory states stored in memory, and / or operate as servers in various embodiments, for example. As examples, network devices capable of operating as servers or otherwise may include dedicated rack servers, desktop computers, laptop computers, set-top boxes, tablet computers, netbooks, smartphones, wearable devices, integrated devices combining two or more features of the aforementioned devices, the like, or any combination thereof. For example, signal packets and / or frames may be exchanged, for example, between server and client devices and / or other types of network devices, including wireless devices coupled via, for example, wireless networks. It should be noted that the terms server, server device, server computing device, server computing platform, and / or similar terms are used interchangeably. Similarly, the terms client, client device, client computing device, client computing platform, and / or similar terms are used interchangeably. Although in some cases these terms are used in the singular form, for ease of description, for example by reference to “client device” or “server device,” the description, as needed, is intended to cover one or more client devices and / or one or more server devices. Similarly, the reference to “database” is to be understood, as needed, to mean one or more databases and / or portions thereof.

[0073] It should be understood that, for ease of description, a network device (also referred to as a networking device) may be embodied and / or described in relation to a computing device. However, it should be further understood that this description should in no way be construed as limiting the claimed subject matter to a single embodiment, such as a computing device and / or a network device, and instead may be embodied as a variety of devices or combinations thereof, including, for example, one or more illustrative examples. References throughout this specification to an embodiment, an embodiment, an example, an example, and / or the like mean that a particular feature, structure, and / or characteristic described in connection with a particular embodiment and / or example is included in at least one embodiment and / or example of the claimed subject matter. Therefore, the appearance of such phrases (e.g.) throughout this specification in various places does not necessarily intend to refer to the same embodiment or any particular embodiment described. Furthermore, it should be understood that, for example, the specific features, structures, and / or characteristics described can be combined in various ways in one or more embodiments, and thus within the scope of the established claims. Generally, of course, these and other issues vary with context. Therefore, the specific context in which the description and / or use is given provides helpful guidance regarding the inferences to be made. While features described herein as exemplary have been illustrated, those skilled in the art will understand that various other modifications and equivalents may be made without departing from the claimed subject matter. Furthermore, numerous modifications may be made to suit specific circumstances to the teachings of the claimed subject matter without departing from the central concepts described herein. Therefore, it is intended that the claimed subject matter be limited to the specific examples disclosed, but rather that such claimed subject matter may encompass all aspects falling within the scope of the appended claims and their equivalents.
