Method and apparatus for concurrent operation of an SPS receiver and a wireless transmitter

Abstract

A mobile device can be configured to perform concurrent SPS operations and wireless communication when uplink signals transmitted by the mobile device interfere with the reception of Satellite Positioning System (SPS) signals in one or more frequency bands. The mobile device can determine whether the SPS receiver has acquired an SPS signal and is in tracking mode. If the SPS receiver is not in tracking mode, an SPS acquisition process is initiated before initiating a wireless communication session. The SPS acquisition process is performed until the SPS receiver reaches tracking mode, or until a timeout occurs. Once the SPS receiver is in tracking mode, a wireless communication session can be initiated, during which time the SPS receiver can be controlled to perform, for example, signal blanking, measurement exclusion, or disable SPS reception to mitigate interference with the SPS signal.

[0003] Aspects of the present disclosure relate generally to wireless communications and positioning. Background Art

[0004] Receivers for satellite positioning systems (SPS) and transceivers for wireless communication systems are typically embedded in mobile devices such as mobile phones, wearable devices, laptops, Internet of Things (IoT) devices, etc. For example, SPS may include a global navigation satellite system (GNSS) such as a global positioning system (GPS), while wireless communication systems include, for example, terrestrial wireless wide area networks (WWANs), such as long-term evolution (LTE) or fifth-generation new radio (5G NR); non-terrestrial WWANs, such as satellite communication systems, and wireless local area networks (WLANs), such as Wi-Fi. The SPS receiver may receive SPS signals from a satellite vehicle and provide the SPS signals to positioning operations, while the wireless communication transceiver may receive and transmit wireless data and control signals for various communication operations. The wireless communication signal or its harmonics may be in the same frequency band as the SPS signal or very close to the same frequency band. In addition, the wireless communication signal may be transmitted with much greater power than the SPS signal. Therefore, if a mobile device receives SPS signals and simultaneously transmits wireless communication signals to support concurrent communication and positioning operations, the wireless communication signals or their harmonics may interfere with the SPS signals, which may adversely affect the reception of the SPS signals and the positioning operations of the mobile device.

[0005] There are many scenarios where concurrent communication and positioning operations are desirable or even required. As an example, a user may use a mobile device to make a phone call while driving and navigate a location at the same time, or for emergency services. As another example, some applications may concurrently use positioning functions and communication functions, such as real-time location tracking and reporting applications. Thus, there is a need for improvements in the field of wireless communication devices to manage concurrent SPS and wireless communication operations. Summary of the invention

[0006] The mobile device can be configured to perform concurrent SPS operations (such as acquisition and tracking) and wireless communications when the uplink signal transmitted by the mobile device interferes with the reception of satellite positioning system (SPS) signals in one or more frequency bands. The mobile device can determine whether the SPS receiver has acquired the SPS signal and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition process is initiated before initiating a wireless communication session. The SPS acquisition process is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, a wireless communication session can be initiated, during which the SPS receiver is controlled to, for example, perform signal blanking, measurement exclusion or prohibit SPS reception to mitigate interference with the SPS signal. The mobile device can measure the SPS signal in the first frequency band interfered by the uplink signal transmission within one or more measurement dwell times, and the one or more measurement dwell times are aligned with the uplink signal transmission (e.g., actually aligned or effectively aligned), and are not longer than the shutdown duration of the uplink signal transmission. The SPS signal in the first frequency band can be used for acquisition state and tracking state. Furthermore, SPS signals in a second frequency band that are not interfered with by uplink signal transmissions may be measured during the on-duration or both the on-duration and off-duration of uplink signal transmissions and may be used for SPS signal acquisition and tracking.

[0027] Several illustrative embodiments will now be described with reference to the accompanying drawings, which form a part of this specification. Although specific embodiments are described below in which one or more aspects of the present disclosure may be implemented, other embodiments may be used and various modifications may be made without departing from the scope of the present disclosure or the spirit of the appended claims.

[0028] Satellite positioning system (SPS) receivers and wireless transmitters, such as wireless wide area network (WWAN) and wireless local area network (WLAN) transmitters, are typically embedded in mobile devices (such as mobile phones), wearable devices, laptops, Internet of Things (IoT) devices, or semi-autonomous or autonomous vehicles (such as ground vehicles, i.e., self-driving cars or trucks), or aerial vehicles (such as unmanned aerial vehicles (UAVs) sometimes referred to as drones). SPS receivers can receive SPS signals from satellite vehicles and perform positioning operations based on the received SPS signals. SPS receivers can support different global or regional positioning systems, such as global positioning system (GPS) signals, global navigation satellite system (GLONASS) signals, Galileo signals, BeiDou signals, and / or signals of other types of satellite positioning systems.

[0029] The wireless transmitter transmits and receives wireless signals for various communication operations, including data and control. The WWAN transmitter can support various communication systems, including, for example, fourth generation (4G) systems such as long-term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-APro systems, and fifth generation (5G) systems that can be referred to as new radio (NR) systems. These systems can use technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread spectrum orthogonal frequency division multiplexing (DFT-S-OFDM). In addition, the WWAN transmitter can support non-terrestrial communication systems, such as satellite-based communication systems. In some implementations, satellite-based communication systems can be combined with terrestrial wireless communication systems (such as 5G new radio (NR) networks). In such a system, mobile devices can access satellites, also known as satellite vehicles (SVs), instead of terrestrial base stations, which can connect to earth stations, also known as ground stations or non-terrestrial (NTN) gateways, which in turn can connect to 5G networks. WLAN transmitters can support various communication systems, including Wi-Fi, Long Term Evolution (LTE) Direct, etc.

[0030] WWAN (land-based or non-land-based) and WLAN signals (hereinafter referred to as "wireless network signals") or their harmonics may be in the same or nearly the same frequency band as the SPS signal, and may interfere with the SPS signal, which may adversely affect the positioning operation of the mobile device. For example, wireless communication transmissions to some satellite vehicles may be at least partially in the Institute of Electrical and Electronics Engineers (IEEE) L1 band. In addition, wireless communication signals such as those with satellite communication systems can be transmitted at a power much greater than the power (e.g., approximately 150db) of the received SPS signal. If a mobile device simultaneously receives an SPS signal and transmits a wireless network signal to support concurrent communication and positioning operations, the wireless network signal or its harmonics may interfere with the SPS signal. This interference may cause problems with SPS reception, including interference with the ability to acquire and track SPS signals, as well as reduced sensitivity and increased probability of false detection, where the interfering signal is misdetected as an SPS satellite signal. False detection may be particularly harmful and may result in very large position errors.

[0031] There are many scenarios where concurrent communication and positioning operations are desirable or even required. As an example, a user may use a mobile device to make a phone call and navigate a location while driving. In another example, emergency services may require concurrent communication and positioning. As another example, some applications may use positioning functions and communication functions concurrently, such as real-time location tracking and reporting applications. For example, in semi-autonomous or autonomous vehicle use cases, concurrent location tracking and communication are necessary. As a result of interference, the ability of the mobile device to provide concurrent communication and positioning operations may be reduced.

[0032] Techniques exist to mitigate the effects of wireless network signal interference on positioning operations. One technique includes improving the isolation of the SPS and WWAN / WLAN components on the device and / or reducing the amount of nonlinearity in the coupling path between the WWAN / WLAN transmitter and the SPS receiver to reduce interference of the wireless network signal on the SPS signal. However, such techniques rely on complex hardware filters, which are difficult and / or expensive to design to provide adequate isolation and linearity, particularly when the interfering communication signal transmission is significantly stronger than the received SPS signal, e.g., 150 dB.

[0033] Another technique may include not using the interfered SPS signals for measurement operations, such as measurement exclusion. For example, SPS signals received while transmitting wireless communication signals may be marked as "not used" and the positioning engine will not use these SPS signals. Similarly, rather than marking the interfered SPS signals, the interfered SPS signals may simply not be provided to the positioning engine.

[0034] Another technique may include disabling reception of SPS signals in a particular frequency band whenever a mobile device is connected to a wireless network, and transmitting an uplink signal that may interfere with the SPS signals in that frequency band.

[0035] Another technique may include blanking the interfered SPS signal when the mobile device is actively transmitting on the interfering wireless network signal band or simply connected to the interfering wireless network signal band. Signal blanking can be enabled by additional functions of the SPS receiver. For example, the SPS receiver may include a function that configures the SPS receiver to ignore the radio signal received via the antenna element when enabled. The signal blanking function may include forcing the output of the analog or digital signal processing device or operation to a zero or null value or a sequence of values ​​when the mobile device is transmitting on the interfering wireless network signal band or connected to the interfering wireless network signal band. However, in general, the blanking mode associated with, for example, LTE TDD has a blanking period of 10ms or less and a duty cycle of 50% or less, and the blanking process does not require significant modifications to the SPS signal measurement process. However, in some implementations, such as in the case of satellite communications, the blanking period will need to be greater than 1s, the duty cycle will be greater than 50%, and traditional signal blanking may not ensure optimal operation.

[0036] The SPS receiver can support multiple frequency bands, including one or more bands that are not interfered by wireless transmitters. For example, the SPS receiver can receive signals in the L1 band and the L2 band, the L5 band or the L2+L5 band. The signal in the L1 band is more susceptible to interference than the signal in the L2 band or the L5 band. However, in some cases, compared with the signal in the interfered frequency band (for example, the L1 band), the available signal in the uninterfered frequency band (for example, the L2 or L5 band) is not suitable for the acquisition process. In this case, the interference of the SPS signal caused by the concurrent communication transmission will hinder the acquisition of the SPS signal. In addition, the available technology (such as signal blanking) discussed above for mitigating the impact of wireless signal interference on the positioning operation is not helpful because the reception of the SPS signal is necessary for the SPS signal acquisition.

[0037] Disclosed herein is a technique for supporting concurrent execution of wireless communications and SPS operations such as acquisition and tracking (e.g., where an SPS receiver receives SPS signals in multiple frequency bands). SPS signals in one or more frequency bands (sometimes referred to herein as a first band) may be interfered with by uplink transmissions of a mobile device, while SPS signals in other frequency bands (sometimes referred to herein as a second band) may be less suitable for signal acquisition. When requesting a wireless communication session, the mobile device may determine whether the SPS receiver is already in a tracking state, i.e., has acquired and is tracking an SPS signal. If the SPS receiver is not in a tracking state, a first band signal is used to initiate an SPS acquisition process before transmitting an uplink communication signal to avoid interfering with the SPS signal during acquisition. The SPS acquisition process may be performed until the SPS receiver reaches a tracking state, or, for example, until a timeout is reached. Once the SPS receiver is in a tracking state, or after a timeout is reached, a wireless communication session may be initiated and an uplink communication signal may be transmitted. During a wireless communication session, for example, while transmitting an uplink signal, appropriate techniques may be employed to mitigate interference of the transmitted uplink signal to the SPS signal in the first band, such as signal blanking, measurement exclusion, or disabling SPS reception.

[0038] In some implementations, in the event that a timeout is reached and the SPS acquisition process has not yet been completed, the acquisition operation may be continued, for example, using an SPS signal from the second band or using an SPS signal from the first band in the event of a signal blanking or dwell alignment. Using dwell alignment, the SPS receiver performs a measurement dwell that begins when the wireless transmitter stops transmitting and ends before or when the wireless transmitter starts transmitting. The continued acquisition operation may be seeded with the result of the initial (incomplete) acquisition attempt. For example, during the continued acquisition operation, it is possible to eliminate one or more of the satellite vehicle identification, time and / or frequency window, and dwell time that have been searched in the initial (incomplete) acquisition attempt. Although the use of continued acquisition operations may be worse in terms of sensitivity and / or first positioning time than using a continuous signal in the first band, the process allows wireless communication to begin without further delay and may be better than a complete failure of SPS acquisition after a timeout occurs.

[0039] In one implementation, one or more frequency bands may be interfered by the uplink transmission of the mobile device, and the SPS signals in other frequency bands may not be suitable for signal acquisition. The SPS receiver can align the SPS signal measurement dwell time with the period when the wireless transmitter does not transmit the wireless signal. For example, the start of the uplink signal transmission, as well as the on-duration and off-duration of the uplink signal transmission can be determined. The measurement dwell time of the frequency band interfered by the uplink signal transmission can be based on the off-duration of the uplink signal, and the measurement dwell time can be aligned with the uplink signal transmission. Accordingly, the SPS signal in the interfered frequency band can be measured by the SPS receiver when the uplink signal is not transmitted, and is not measured when the uplink signal is transmitted.

[0040] Figure 1 A simplified diagram of a system 100 is illustrated, wherein the reception of SPS signals by a mobile device 105 may be affected by the transmission of wireless communication signals by the mobile device 105. The SPS signals may be transmitted based on various satellite position signaling standards, such as a global positioning system (GPS), a global navigation satellite system (GLONASS), Galileo, BeiDou, and / or other types of satellite positioning systems. The mobile device 105 may include a satellite positioning system (SPS) receiver that may be compatible with one or more of these satellite position signaling standards. The SPS receiver may process the SPS signals based on the signaling standard to extract information and perform position calculation operations based on the extracted information.

[0041] Mobile device 105 can be a device designed to perform multiple functions, including the ability to determine its own position based on the reception of SPS signals from satellites. Mobile device 105 can perform satellite-based positioning by receiving SPS signals from one or more satellites. As shown here, mobile device 105 receives SPS signals 111, 113 and 115 from positioning satellites 112, 114 and 116, respectively. SPS can be, for example, a global navigation satellite system (GNSS), such as GPS, GLONASS, Galileo or Beidou, or some other local or regional systems, such as Indian Regional Navigation Satellite System (IRNSS), European Geosynchronous Navigation Overlay Service (EGNOS) or Wide Area Augmentation System (WAAS).

[0042] In general, each of the SPS signals 111, 113, and 115 will include timing information related to when the SPS signal was transmitted from the corresponding satellite. Each SPS signal may also include ephemeris information that can be used to determine the position of the satellite when the SPS signal was transmitted. The mobile device 105 can determine when it receives each of the SPS signals 111, 113, and 115. The transmission time and reception time of each SPS signal can be aligned on a common timing reference (such as a common clock) known to the mobile device 105. By taking the difference between the reception time and the transmission time, the mobile device 105 can calculate the flight time associated with each SPS signal for the SPS signal to travel from the corresponding satellite to the mobile device 105. Then, the flight time can be used to calculate the distance between each satellite and the mobile device based on the signal propagation speed, i.e., the speed of light. Once the distance between each satellite and the mobile device is found, the position of the mobile device 105 can be calculated using multi-point positioning (multilateration) based on the known position of each satellite and the distance between each satellite and the mobile device 105.

[0043] In addition to satellite-based positioning, an important category of functions performed by the mobile device 105 involves wireless communications. Wireless communications can serve as an important link connecting the mobile device 105 with other devices such as servers and other mobile devices through private and / or public networks. This can include communication through various types of wireless networks, including wireless local area networks (WLANs) and wireless wide area networks (WWANs), among others. Examples of WLANs can be different types of Wi-Fi networks, such as those implemented based on various 802.11 standards. Figure 1 Wireless communications between the mobile device 105 and a terrestrial base station, a satellite carrier, and an access point are illustrated. However, other examples of wireless communications may include peer-to-peer communications between mobile devices, such as Wi-Fi Direct, Long Term Evolution (LTE) Direct, or Proximity-based Services (ProSe) Direct Communications (PC5), etc. Examples of WWAN may include satellite communications, 5G NR, LTE, Wideband Code Division Multiple Access (WCDMA), etc. Additional examples of wireless communications may include Near Field Communications (NFC), Bluetooth communications, etc.

[0044] As used herein, the terms "mobile device" and "base station" are not intended to be specific or otherwise limited to any particular radio access technology (RAT), unless otherwise noted. In general, a mobile device can be any wireless communication device used by a user to communicate over a wireless communication network (e.g., a mobile phone, a router, a tablet computer, a laptop computer, a tracking device, a wearable (e.g., a smart watch, glasses, augmented reality (AR) / virtual reality (VR) headsets, etc.), a semi-autonomous or autonomous ground vehicle (e.g., a car, a truck, a motorcycle, a bicycle, a drone, etc.), a semi-autonomous or autonomous aerial vehicle (e.g., a UAV or drone), an Internet of Things (IoT) device, etc.). A mobile device can be mobile or can be (e.g., at certain times) stationary and can communicate with a radio access network (RAN). As used herein, the term "mobile device" and "base station" are not intended to be specific or otherwise limited to any particular radio access technology (RAT), unless otherwise noted. In general, a mobile device can be any wireless communication device used by a user to communicate over a wireless communication network (e.g., a mobile phone, a router, a tablet computer, a laptop computer, a tracking device, a wearable (e.g., a smart watch, glasses, an augmented reality (AR) / virtual reality (VR) headset, etc.), a semi-autonomous or autonomous ground vehicle (e.g., a car, a truck, a motorcycle, a bicycle, a drone, etc.), a semi-autonomous or autonomous aerial vehicle (e.g., a UAV or drone), an Internet of Things (IoT) device, etc.). A mobile device can be mobile or can be (e.g., at certain times) stationary and can communicate with a radio access network (RAN). A "mobile device" may be interchangeably referred to as a "user equipment," "access terminal" or "AT," "client device," "wireless device," "subscriber equipment," "subscriber terminal," "subscriber station," "user terminal" or UT, "mobile terminal," "mobile station," or variations thereof. Typically, a mobile device may communicate with a core network via a RAN or, in some cases, a communication satellite, and through the core network, the mobile device may connect to external networks such as the Internet and to other mobile devices. Of course, other mechanisms for connecting to the core network and / or the Internet are also possible for the mobile device, such as through a wired access network, a wireless local area network (WLAN) network (e.g., based on IEEE 802.11, etc.), and the like.

[0045] exist Figure 1 In the example shown, the mobile device 105 performs wireless communications by sending signals to and receiving signals from one or more communication satellites via a wireless communication link. For example, the mobile device 105 can send a communication signal 121 to a communication satellite 122 over a wireless communication link. It should be understood that the communication satellite 122 is separate from the positioning satellites 112, 114, and 116 and is not part of the SPS. The communication satellite 122 can be part of a wireless communication network, such as 5G New Radio (NR) or some other wireless access type, such as code division multiple access (CDMA). The mobile device 105 can transmit data and control signals to the communication satellite 122 via the wireless communication link 121, and receive data and control signals from the communication satellite 122.

[0046] like Figure 1As further illustrated in FIG. 1 , the mobile device 105 may additionally or alternatively support wireless communications using one or more radio access technologies (RATs), such as Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), LTE, High Rate Packet Data (HRPD), IEEE 802.11 WiFi (also known as Wi-Fi), (BT), Worldwide Interoperability for Microwave Access (WiMAX), 5G New Radio (NR), etc. For example, the mobile device 105 can send a communication signal 125 to the base station 126 over the wireless communication link, and send a communication signal 129 to the access point 130 over the wireless communication link. For example, the base station 126 can be part of a radio access technology (RAT) and can support LTE or 5G NR communication, and the access point 130 can support IEEE 802.11 WiFi. Figure 1 Wireless signals transmitted from the mobile device 105 (as opposed to wireless signals received by the mobile device 105) are highlighted because the various embodiments discussed herein are directed to techniques for reducing interference caused by such transmitted signals, but it should be understood that the mobile device 105 can transmit and receive communication signals via wireless communication links.

[0047] If the mobile device 105 simultaneously attempts to receive SPS signals such as signals 111, 113, and 115 and transmit wireless communication signals such as signals 121, 125, and 129, interference may cause problems with SPS signal reception, including failure to acquire SPS signals, as well as reduced sensitivity and increased probability of false detection. For example, if any of the received SPS signals 111, 113, and 115 and the transmitted wireless signals 121, 125, and 129 utilize common or overlapping, or even adjacent frequency bands, interference may occur. For example, interference may be caused by spectrum transmissions from adjacent or close frequency bands, especially when the transmission power is significantly greater than the SPS signal, which may cause the signal band to be saturated when the wireless communication signal is transmitted, thereby preventing the SPS receiver in the mobile device 105 from receiving SPS signals in those bands. Even when the received SPS signals 111, 113, and 115 and the transmitted wireless signals 121, 125, and 129 do not utilize common or overlapping frequency bands, interference may further occur when intermodulation products introduce interference.

[0048] Figure 2 An example of an SPS signal and its frequency band 200 is shown. Figure 2As shown, the first group of SPS signals may occupy a frequency band of 1166-1249 MHz, which corresponds to the IEEE L2 band and the L5 band. The first group of SPS signals may include, for example, IRNSS signals, Beidou B2a signals (labeled as "BDS B2a"), Galileo E5a and E5b signals (labeled as "GAL E5a" and "GAL E5b"), GPS L2 and L5 signals (labeled as "GPS L2" and "GPS L5"), and GLONASS G2, L2OC and L3OC signals (labeled as "GLOG2", "GLO L2OC" and "GLO L3OC", respectively). Each of the first group of SPS signals includes a carrier of a predetermined frequency. For example, the carrier frequency of each of IRNSS, BDS B2a, GAL E5a and GPS L5 is 1176 MHz, the carrier frequency of GAL E5b and BDS B2 is 1207 MHz, the carrier frequency of GPS L2 is 1227.6 MHz, and the carrier frequency of GLO G2 is 1246 MHz+k*437.5 kHz, where k ranges from -7 to +6, the carrier frequency of GLO L2OC is 1248.06 MHz, and the carrier frequency of GLO L3OC is 1202.025 MHz.

[0049] In addition, the second group of SPS signals may occupy a frequency band of 1559-1606 MHz, which corresponds to the IEEE L1 band. The second group of SPS signals may include, for example, a BeiDou B1 signal (labeled as "BDS B1"), a BeiDou B1C signal (labeled as "BDS B1C"), a Galileo E1 signal (labeled as "GAL E1"), a GPS L1 and L1C signal (labeled as "GPS L1" and GPS L1C), and a GLONASS G1 and L1OC signal (labeled as "GLO G1" and "GLO L1OC"). Each of the second group of SPS signals also includes a carrier of a predetermined frequency. For example, the carrier frequency of BDS B1 is 1561 MHz, the carrier frequency of each of BDS B1C, GAL E1, GPS L1 and GPS L1C is 1575.42 MHz, the carrier frequency of GLO L1OC is 1600.995 MHz, and the carrier frequency of GLO G1 is 1602 MHz+k*562.5 kHz, where k ranges from -7 to +6.

[0050] WWAN signals such as LTE and WLAN signals may be outside the L1 and L2+L5 bands of the aforementioned SPS signals. However, intermodulation (IM) products or harmonic distortion of WLAN and WWAN signals may result in signals falling into the L1 band and potentially interfering with SPS signals.

[0051] As examples, the following interference signals may be caused by concurrent operation of SPS and communication transceivers: (A) Long Term Evolution (LTE) B13 / B14 (777-798 MHz uplink), the second harmonic falls in the SPS L1 band (e.g., 2×780 MHz=1600 MHz); (B) 800 MHz WWAN and 2.4 GHz WLAN, the second-order IM product (IM2) falls at 1.6 GHz (e.g., 2.4 GHz–800 MHz); and (C) 1.7 / 1.9 GHz WWAN and 5 GHz WLAN, the third-order IM product falls at 1.6 GHz (e.g., 5 GHz–2×1.7 GHz).

[0052] It can be seen that although 2.4GHz or 5GHz WLAN signals and 800MHz or 1.7 / 1.9GHz WWAN signals do not necessarily use the same frequency as the SPS signal in the L1 band, the IM products generated by the mixing of such WLAN and WWAN signals may fall into the same frequency used by the SPS signal.

[0053] In addition, some WWAN signals, such as those using satellite communication systems, are transmitted in the 1610-1625.5 MHz range, for example, by Figure 2 202 in FIG. 1 , and therefore, may at least partially overlap with the L1 band. In addition, the uplink transmit signal level of some communications may be about 150 dB stronger than the received SPS signal. Accordingly, during uplink transmission, the front end of the L1 band radio receiver will be saturated, for example, in one or more parts of the front end, including RF (radio frequency), IF (intermediate frequency) or DFE (digital front end), which will prevent the reception of all SPS signals within the L1 band.

[0054] The SPS receiver in the mobile device 105 may be able to receive multiple frequency bands, including one or more bands (first band) that will be interfered with by uplink transmissions and one or more bands (second band) that are less likely to be interfered with. In addition, the SPS signals available in the second band may be less suitable for the acquisition process than the SPS signals in the first band. For example, the SPS receiver in the mobile device 105 may receive frequency bands in the L1 band and the L2 and / or L5 bands. Uplink communication transmissions may interfere with the reception of SPS signals in the L1 band, but will not interfere with the reception of SPS signals in the L2 band or the L5 band. However, SPS signals in the L2 band or the L5 band are not as suitable for the acquisition process as SPS signals in the L1 band.

[0055] Interference to SPS signals in the first band (e.g., L1 band) may prevent the mobile device 105 from acquiring SPS signals for tracking when transmitting communication signals. In addition, interference mitigation techniques such as signal blanking cannot be used during SPS signal acquisition because these techniques eliminate SPS signals. If the SPS signal cannot be received during the acquisition process due to interference or interference mitigation techniques, the SPS receiver may never reach a tracking state, and concurrent operation of SPS tracking and wireless communication may not be possible.

[0056] Therefore, in one implementation, concurrent operation of SPS tracking and wireless communication is performed by first determining whether the SPS receiver is in a tracking state (e.g., characterized by a small satellite search space in the frequency domain and the time domain). If the SPS receiver is not in a tracking state, an SPS acquisition process may be initiated before initiating a wireless communication session. The SPS acquisition process may be performed until the SPS receiver reaches a tracking state, or, for example, until a timeout is reached. Once the SPS receiver is in a tracking state, or after a timeout is reached, a wireless communication session may be initiated. During a wireless communication session, for example, while transmitting an uplink signal, appropriate techniques may be employed to mitigate interference to the SPS signal, such as signal blanking, measurement exclusion, or prohibition of SPS reception.

[0057] If the timeout is reached without SPS signal acquisition, the SPS acquisition process can end and wireless communication can begin. In some implementations, entities such as location service clients can be given the option of continuing the SPS signal acquisition process or continuing wireless communication. In another implementation, if the timeout is reached without SPS signal acquisition, the acquisition operation can be continued, for example, using an SPS signal from a first band with signal blanking or dwell alignment or using an SPS signal from a second band (non-interference band). With signal blanking, the SPS receiver sets the SPS signal received when the wireless transmitter transmits a communication signal to a sequence of zero or null values ​​or values. With dwell alignment, the SPS receiver does not measure the SPS signal when the wireless transmitter transmits a communication signal, for example, by aligning the measurement dwell time to measure the SPS signal only during the shutdown transmission period of the wireless transmitter. The continued acquisition operation can be carried out with the result of the initial (incomplete) acquisition attempt as a seed. Therefore, a wireless communication session can start after reaching the timeout, but the SPS acquisition process can continue.

[0058] Measurements of SPS satellite signals are typically generated based on measurement dwells anywhere from 20 milliseconds to 12 seconds. A measurement dwell typically consists of a coherent integration period (e.g., 20 milliseconds) and multiple (e.g., 50) non-coherent ones. A measurement dwell uses a correlation window consisting of time and frequency dimensions. The window dimensions are sized to cover the SPS receiver's time and frequency uncertainties for a given satellite, which are derived from the SPS receiver's knowledge of its position and time and its knowledge of the satellite's position. These uncertainties are typically largest during the initial acquisition process, during which the SPS receiver may have only a rough knowledge of its position and time, and are typically smallest during the tracking process, during which the SPS receiver can accurately predict the time and frequency of a given satellite signal.

[0059] During a wireless transmission session, a wireless transmitter may be active only part of the time. For example, the wireless transmitter may be active for 2 seconds out of every 2.56 seconds, or for some other duration and / or ratio. Whenever the wireless transmitter is active, the wireless transmitter may provide an indication to the SPS receiver, such as a transmission activity indicator. In some implementations, the wireless transmitter may also provide an indication to the SPS receiver of how long the wireless transmitter will be on or off. Alternatively, the duration of the on and off periods of the wireless transmitter may be a fixed amount that is known in advance by the SPS receiver.

[0060] When the wireless transmission session is active, the SPS receiver can use the SPS signal received when the wireless transmitter is turned off to perform measurement dwell. In other words, the SPS signal measurement dwell time can be aligned with the period when the wireless transmitter does not transmit the wireless signal. The SPS receiver can limit the number of incoherents to the maximum multiple of the coherent integration period that meets the off period of the wireless transmitter. The measurement dwell time is the total integration time generated based on the product of the coherent integration interval and the number of incoherents. The number of incoherents can be selected to ensure that the total integration time is equal to or less than the off duration of the uplink signal transmission. Accordingly, when there is no uplink signal transmission, the SPS signal received in the interfered frequency band can be measured by the SPS receiver, but not measured during the uplink signal transmission to avoid interference. In some implementations, the SPS receiver can continue to receive the SPS signal in the interfered frequency band, but can blank the SPS signal during the on duration of the uplink signal transmission. The SPS receiver may include blanked signals in the measurement operation, wherein the blanked signals do not contribute substantially to the measurement results, and report a timestamp associated with the measurement that effectively aligns the measurement dwell time with the off-duration of the uplink signal transmission.

[0061] In some implementations, the SPS receiver may perform multiple measurement dwells during the wireless transmitter off period. For example, the sum of the total integration time of each measurement dwell should conform to the off period. This option may be useful for applications such as semi-autonomous or autonomous ground or aerial vehicles that require higher rate position updates. For example, a typical application of this type may require a 10Hz position update, which means a 100 millisecond measurement dwell. In this case, if the wireless transmitter off period is 0.56 seconds, up to five measurement dwells may be performed during the off period.

[0062] In some implementations, SPS signal data received during a wireless transmitter off period can be stored in memory and played back to the correlator hardware so that measurement processing can be performed when the wireless transmitter is active. Storing SPS signal data for processing during signal transmission optimizes the use of correlators and other hardware resources, but at the expense of memory for signal storage. In addition, SPS signal data received during a wireless transmitter off period can be used for non-coherent integration with SPS signal data received from consecutive off periods. For example, if a measurement operation for a given satellite is unsuccessful within an available off period, the SPS receiver can save the correlation results and continue the non-coherent integration during the next available off period.

[0063] During the acquisition process, if the measurement operation for a given satellite using a measurement dwell aligned with the wireless transmitter off period is successful, the SPS receiver may perform a verification measurement operation for the satellite. The verification measurement operation may be performed in the same or subsequent wireless transmitter off period. Compared with the measurement operation used for acquisition, the verification measurement operation generally has a detection threshold with a smaller probability of false detection and a smaller correlation window. It may also have a longer non-coherent integration period. In addition, after the verification operation, the SPS receiver may perform bit edge detection or auxiliary code synchronization operations in one or more subsequent wireless transmitter off periods. Non-coherent integration can be used to combine results from more than one off period.

[0064] In addition, during the acquisition process, it may be desirable to decode time parameters broadcast by satellites, such as the time of week (TOW) parameter broadcast by GPS satellites. The knowledge of this time parameter allows the receiver to reduce its time uncertainty, thereby completing the acquisition process and generating a position fix faster. Since the SPS receiver can only receive part of the SPS signal when the wireless transmitter is turned off, it may not be able to synchronize to the broadcast data stream and decode the time parameters. To address this problem, the SPS receiver can use the acquisition results from the interfered SPS band to initiate a tracking process on a second SPS band that is not interfered with by the wireless transmitter. The SPS receiver can continuously receive signals on the second SPS band, enabling it to synchronize to the broadcast data stream and decode the time parameters.

[0065] Once the acquisition process is complete, the SPS receiver can track the SPS signals received on the first SPS band (i.e., the interfered band) using measurement dwells aligned with the wireless transmitter off period. The SPS receiver can additionally track the SPS signals continuously received on the second SPS band (i.e., the non-interfering band). In some implementations, the SPS signals received on the second SPS band (i.e., the non-interfering band) can be tracked only during the wireless transmitter on period, and the SPS receiver can switch to tracking the SPS signals on the first SPS band (i.e., the interfered band) during the wireless transmitter off period.

[0066] For example, Figure 3A A flowchart 300 of a process for concurrently performing wireless transmission and multi-band SPS operations is illustrated. As shown, at block 302, the mobile device 105 determines to initiate a wireless call, i.e., a wireless communication session. For example, a request to initiate wireless communication may be received, for example, from the mobile device 105 or from an external entity.

[0067] At decision 304, the mobile device 105 determines whether the SPS receiver is performing SPS tracking, i.e., whether it is in a tracking state. If the SPS receiver is already in a tracking state, the wireless communication transmission can start immediately, and the process can flow to block 310. If the SPS receiver is not in a tracking state, the mobile device 105 can leave time for SPS acquisition before starting the wireless communication transmission. For example, the mobile device 105 can delay the initiation of wireless communication, or in some implementations, if the wireless communication has been initiated, the mobile device 105 can pause the wireless communication transmission.

[0068] At block 306, the mobile device 105 performs an SPS acquisition process before initiating a wireless call, during which SPS signals are acquired and tracked by an SPS receiver. During SPS signal acquisition, a relatively large satellite search space in the frequency domain and time domain may be used compared to that used during SPS tracking. The acquisition of SPS signals may use a frequency band of SPS signals that would be interfered with if an uplink signal were transmitted by the mobile device 105.

[0069] The SPS acquisition process may include multiple operations. For example, the initial acquisition operation may be used to identify available satellite vehicles, for example, using a relatively large correlation window in the frequency domain and time domain with a relatively high probability of false alarm (Pfa). The verification measurement operation uses a detection threshold with a relatively small probability of false detection (Pfa) and a relatively small correlation window. The SPS receiver may additionally perform at least one of bit edge detection or auxiliary code synchronization operations. In addition, a time decoding operation may be used to synchronize to the broadcast data stream and decode the time parameters in the SPS signal, thereby allowing the SPS receiver to reduce time uncertainty and shrink the search space for signal tracking. The SPS acquisition time may depend on the SPS receiver state (e.g., cold start, warm start or hot start mode), whether the SPS receiver has valid almanac data and ephemeris data, whether it has a rough knowledge of its position, etc. The acquisition time may also depend on the environment, such as whether the mobile device is outdoors, in an urban canyon, indoors, etc., and the number and position of satellites. The SPS acquisition process may include a timeout, and if the acquisition process takes too long, such as 4 seconds or longer, the timeout may be used to stop the SPS acquisition process or change the process. The length of the timeout may be chosen as a compromise between the probability of successful SPS acquisition and the speed at which wireless communication is completed.

[0070] For example, at decision 308, it is determined whether the SPS acquisition is successful. Decision 308 may occur before the timeout period, for example, if the acquisition procedure ends prematurely, or after the timeout period. If the SPS acquisition is successful, the process flows to block 310, and if the SPS acquisition is unsuccessful, the process may flow to block 312. In some implementations, if the SPS signal has not been acquired at the end of the timeout period, the SPS acquisition process may end, and the process may proceed to wireless communication without SPS signal tracking. In some implementations, the entity requesting wireless communication (e.g., an external entity or a user of a mobile device) may be notified of the SPS acquisition timeout, and may be given the option of continuing wireless communication or continuing to attempt to acquire the SPS signal.

[0071] When the SPS signal has been acquired and the SPS receiver is in the tracking state (e.g., as determined at decision 304 or 308), the process flows to box 310, during which the mobile device 105 performs concurrent wireless calls and SPS tracking, for example, by controlling the SPS receiver to mitigate interference when transmitting wireless communication signals. For example, when transmitting wireless signals, the SPS receiver will continue to continuously track SPS signals from one or more undisturbed frequency bands while blanking the SPS signals on one or more interfered bands. For example, whenever the wireless transmitter is active, the SPS signal in the interfered band can be blanked by replacing the signal with a zero signal or a fixed sequence. Instead of signal blanking, measurement exclusion can be used, in which SPS signals on all bands including one or more interfered bands are received, but measurements of SPS signals in the frequency bands interfered by the wireless transmitter are excluded in positioning or timing calculations. Another alternative is to completely prohibit the reception of SPS signals in the frequency bands interfered by the wireless transmitter, while continuing to receive signals on one or more other SPS bands that are not interfered with.

[0072] If the SPS signal has not been acquired at the end of the timeout period and the SPS receiver is not in a tracking state, e.g., as determined at decision 308, the process may flow to block 312, during which the mobile device 105 initiates wireless communication and continues the SPS acquisition process. For example, in some implementations, the SPS receiver may continue the SPS acquisition process using an SPS signal on a frequency band (Band 2) that is not interfered with by wireless communication signal transmissions. In another implementation, the SPS receiver may continue the SPS acquisition process using an SPS signal on a frequency band (Band 1) that is interfered with by wireless communication signal transmissions using signal blanking or dwell alignment. For example, using signal blanking, the SPS receiver sets the SPS signal received in Band 1, where the wireless transmitter is simultaneously transmitting a communication signal, to 0 or a null value or a sequence of values.

[0073] In another example, measurement dwell alignment can be used so that the SPS receiver measures the SPS signal when the wireless transmitter does not transmit a communication signal, and does not measure the SPS signal when the wireless transmitter transmits a communication signal. For example, the wireless transmitter can provide a transmission activity indicator to the SPS receiver, indicating when the wireless transmitter starts or stops wireless transmission. When the transmission activity indicator indicates that the wireless transmitter has stopped wireless transmission, the SPS receiver can start measuring the SPS signal. The SPS receiver can limit the measurement dwell time to no longer than the shutdown duration of the signal transmission. For example, the shutdown duration of the uplink signal transmission can be provided to the SPS receiver, or it can be preconfigured and stored in a memory. The measurement dwell time is the total integration time generated based on the product of the coherent integration interval and the number of incoherents. The SPS receiver can adjust the number of incoherents to ensure that the total integration time is equal to or less than the shutdown duration of the uplink signal transmission.

[0074] The results of the initial (incomplete) acquisition attempt may be used as a seed for continued acquisition operations. For example, during continued acquisition operations, it may be possible to eliminate one or more of the satellite vehicle identifications, time and / or frequency windows, and dwell times that have been searched in the initial (incomplete) acquisition attempt.

[0075] Once SPS signal acquisition in block 312 is complete, the process may flow to block 310 for concurrent wireless communications and SPS tracking as discussed above.

[0076] Figure 3B 3 is an expanded flowchart 320 illustrating concurrent execution of a wireless transmission and a multi-band SPS operation process. Flowchart 320 illustrates a process where the mobile device 105 has already made a wireless call, e.g., wireless communication has been initiated. For example, the mobile device 105 may have initiated the wireless call before SPS acquisition occurs. In another example, the mobile device 105 may have already performed Figure 3A , and concurrent wireless call and SPS tracking in block 310 may be being performed when the SPS receiver exits the tracking state, for example due to failure to receive an SPS signal for a period of time, but the wireless call continues.

[0077] At block 322, the mobile device 105 conducts a wireless call. The mobile device 105 may or may not be concurrently conducting SPS tracking.

[0078] At decision 324, the mobile device 105 determines whether the SPS receiver is performing SPS tracking. If the SPS receiver is in the tracking state, the concurrent wireless call and SPS tracking can continue, such as Figure 3AIf the SPS receiver is not in the tracking state, the process may flow to block 326 to allow time for SPS acquisition before transmitting the wireless communication signal. For example, the mobile device 105 may not have been performing SPS tracking. In another implementation, at block 322, the mobile device 105 may have been performing concurrent wireless calls and SPS tracking, but the mobile device 105 may have exited the tracking state, for example, which may be caused by the SPS receiver not detecting an SPS signal for a period of time.

[0079] At block 326, the mobile device 105 can pause or stop wireless transmissions to allow time for SPS acquisition.

[0080] At block 328, the mobile device 105 performs an SPS acquisition process during which the SPS signal is acquired and tracked by the SPS receiver, e.g., similar to Figure 3A Block 306 in the SPS acquisition process may include a timeout.

[0081] When the SPS signal has been acquired and the SPS receiver is in a tracking state, eg, after block 328, the process flows to block 330 during which the mobile device 105 begins wireless transmissions again.

[0082] At block 332, the mobile device 105 may perform concurrent wireless calls and SPS tracking, for example, by controlling the SPS receiver to mitigate interference when transmitting wireless communication signals, for example, similar to Figure 3A Frame 310 in FIG.

[0083] Figure 3C 340 is a flowchart illustrating an expansion of the concurrent execution of wireless transmission and multi-band SPS operation process. Figure 3B 320, flowchart 340 illustrates a process in which mobile device 105 has made a wireless call, such as initiating wireless communication. For example, mobile device 105 may have performed Figure 3A , and may be performing concurrent wireless calls and SPS tracking in block 310 when the SPS receiver exits the tracking state, for example due to failure to receive an SPS signal for a period of time, but the wireless call continues.

[0084] At block 342, the mobile device 105 conducts a wireless call. The mobile device 105 may or may not be concurrently conducting SPS tracking.

[0085] At decision 344, the mobile device 105 determines whether the SPS receiver is performing SPS tracking. If the SPS receiver is in the tracking state, the concurrent wireless call and SPS tracking can continue, such as Figure 3AIf the SPS receiver is not in the tracking state, the process may flow to block 346 to allow time for SPS acquisition before transmitting the wireless communication signal. For example, at block 342, the mobile device 105 may have been conducting a concurrent wireless call and SPS tracking, but the mobile device 105 may have exited the tracking state, for example, which may be caused by the SPS receiver not detecting an SPS signal for a period of time.

[0086] At block 346, the mobile device 105 may drop the wireless call.

[0087] At block 348, the mobile device 105 may return to Figure 3A Frame 302.

[0088] Figure 4 is a block diagram illustrating a communication system 400 that can facilitate concurrent reception of SPS signals and transmission of wireless communication signals. Figure 4 As shown, communication system 400 includes wireless transmitter 402, controller 404, and SPS receiver 406. Communication system 400 may be part of a mobile device, such as mobile device 105.

[0089] For example, the wireless transmitter 402 may be part of a wireless transceiver and may transmit wireless communication signals in a wireless communication link, for example, when enabled by the controller 404 via a transmit (Tx) enable signal. For example, the wireless transmitter 402 may transmit wireless signals of various communication protocols / standards, such as satellite communication, 5G NR, LTE, Wi-Fi, etc., and may communicate with wireless transmitters, such as Figure 1 A communication satellite 122, a base station 126, or an access point 130 is shown. Whenever the wireless transmitter 402 is actively transmitting, the wireless transmitter 402 may assert a transmission (Tx) activity indicator signal.

[0090] Controller 404 can manage Figure 3A , 3B 3C. For example, the controller 404 may provide an SPS enable signal to the SPS receiver 406 to indicate when the SPS receiver 406 starts SPS acquisition and tracking. When the SPS receiver 406 is in the tracking state, the controller 404 may receive a tracking state indicator signal from the SPS receiver 406. The controller 404 may also provide a transmit (Tx) enable signal to the wireless transmitter 402 to indicate when the wireless transmitter 402 may start transmitting wireless communication signals.

[0091] The SPS receiver 406 receives SPS signals, which can be used for positioning of the mobile device. For example, the SPS receiver 406 can receive SPS signals of various satellite position signaling standards, such as global positioning system (GPS), global navigation satellite system (GLONASS), Galileo, Beidou and / or other types of satellite positioning systems. The SPS receiver 406 can be divided into a measurement engine (ME) 408 and a position engine (PE) 410, which operate independently in some cases. In some implementations, the position engine (PE) 410 can be outside the mobile device, such as in a location server. The SPS receiver 406 receives SPS signals in two or more frequency bands, for example, a first band (Band 1) on the Band 1 Rx input and a second band (Band 2) on the Band 2 Rx input. As illustrated in the interference path, the transmission of the wireless communication signal by the wireless transmitter 402 may interfere with the reception of the SPS signal on one or more SPS signal (frequency) bands, for example, interfering with the Band 1 signal received on the Band 1 Rx input. However, as illustrated, wireless communication signals transmitted by wireless transmitter 402 may not interfere with reception of SPS signals on other frequency bands (eg, Band 2 signals received on Band 2 Rx input).The interference mechanism may be radiated or conducted.

[0092] SPS receiver 406 may receive an SPS enable signal from controller 404 that instructs SPS receiver 406 to perform, for example, SPS acquisition and tracking. SPS receiver 406 may also provide a tracking status indicator signal to controller 404, for example, to indicate when SPS receiver 406 has acquired an SPS signal and is in a tracking state.

[0093] The SPS receiver 406 may further receive a transmission activity indicator signal from the wireless transmitter 402 indicating when the wireless transmitter 402 is transmitting a wireless communication signal. In response to the transmission activity indicator signal from the wireless transmitter 402, the SPS receiver 406 may control the measurement engine (ME) 408 and / or the location engine (PE) 410 to mitigate interference of the transmission of the wireless communication transmission to the SPS signal in at least one of the multiple frequency bands (e.g., the signal received on the Band 1 Rx input), while continuing to receive the SPS signal in the frequency band that is not interfered by the wireless transmission (e.g., the signal received on the Band 2 Rx input). For example, whenever the transmission activity indicator signal indicates that the wireless transmitter 402 is transmitting a wireless communication signal, the measurement engine (ME) 408 in the SPS receiver 406 may blank the SPS signals received on the Band 1 Rx input, for example, marking these signals with a zero signal or a fixed sequence. Alternatively, when the transmission activity indicator signal indicates that the wireless transmitter 402 is transmitting wireless communication signals, the measurement engine (ME) 408 may completely prohibit receiving signals on the Band 1 Rx input. In another implementation, when the transmission activity indicator signal indicates that the wireless transmitter 402 is transmitting wireless communication signals, when the signals received on the Band 1 Rx input are provided to the location engine (PE) 410, these signals may be marked as "not used" by the measurement engine (ME) 408, or the measurement engine (ME) may simply not send these signals to the location engine (PE). Similarly, the location engine (PE) 410 may receive the Tx activity indication signal directly from the wireless transmitter 402 or the controller 404, and may not use the signals received on the Band 1 Rx input when the transmission activity indicator signal indicates that the wireless transmitter 402 is transmitting wireless communication signals.

[0094] The SPS receiver 406 can perform SPS signal acquisition and tracking using an SPS signal received in a frequency band interfered by the transmitted wireless communication signal (e.g., a Band 1 signal received on a Band 1 Rx input) by aligning the measurement dwell time with the off duration of the wireless communication signal transmission. The SPS receiver 406 can receive a transmission activity indicator signal from the wireless transmitter 402 indicating when the wireless transmitter 402 is transmitting a wireless communication signal. The SPS receiver 406 can also receive an indication of the duty cycle of the wireless communication signal transmission, for example, together with the transmission activity indicator signal, as part of the transmission activity indicator signal, or previously configured and stored in a memory. The SPS receiver 406 can configure the measurement dwell time to be equal to or less than the off duration of the wireless communication signal transmission. For example, the measurement dwell time can be a total integration time based on the product of the coherent integration interval and the number of incoherents, and the number of coherents can be selected to produce a total integration time equal to or less than the off duration. The SPS receiver 406 aligns the measurement dwell time with the off-duration of the wireless communication signal transmission, for example, by starting to measure the Band 1 signal received on the Band 1 Rx input when the transmission activity indicator signal indicates that the off-duration of the wireless communication signal transmission begins. The measurement dwell time is limited to be equal to or less than the off-duration of the wireless communication signal transmission, and accordingly, the Band 1 signal received on the Band 1 Rx input is not measured during the wireless communication signal transmission, thereby avoiding interference caused by the wireless communication signal transmission. Accordingly, the SPS signal in frequency band 1 received on the Band 1 Rx input can be used for the acquisition process and SPS signal tracking without interference caused by the wireless communication signal transmission.

[0095] In another implementation, the SPS receiver 406 may configure the measurement dwell time to be greater than the off-duration of the wireless communication signal transmission. The SPS receiver 406 may continue to receive the band 1 signals received on the band 1 Rx input during the wireless communication signal transmission, i.e., during the on period of the wireless transmission, but may blank these signals, for example, using signal blanking. The SPS receiver 406 may include the blanked signals in the measurement operation, wherein the blanked signals do not contribute substantially to the measurement results, and report a timestamp associated with the measurement, which effectively aligns the measurement dwell time with the off-duration of the uplink signal transmission.

[0096] The SPS receiver 406 may measure the Band 2 signal received on the Band 2 Rx input during both the OFF and ON durations of the wireless communication signal transmission, because the SPS signal in Band 2 is not interfered with by the wireless communication signal transmission. However, the SPS signal in Band 2 may be less suitable for SPS signal acquisition than the SPS signal in Band 1, and therefore, the SPS signal in Band 2 may be used for SPS signal tracking. In some implementations, the SPS signal in Band 2 may also be used for SPS signal acquisition, for example, decoding time during an acquisition process or other acquisition operation. In some implementations, the SPS receiver 406 may measure the Band 2 signal received on the Band 2 Rx input only during the ON duration of the wireless communication signal, and may switch to measuring the Band 1 signal received on the Band 1 Rx input during the OFF duration of the wireless communication signal (e.g., during tracking or during acquisition and tracking). For example, the SPS receiver 406 may only receive one band at a time, but may be able to switch between multiple bands.

[0097] Figure 5 5 is a signal flow 500 illustrating the concurrent execution of reception of SPS signals and transmission of wireless communication signals by mobile device 105, SPS satellite vehicle (SV) 502, and wireless transceiver 504. For example, SPS SV 502 may be a satellite in any SPS network, such as Figure 1 Satellites 112, 114, and 116 are shown. Wireless transceiver 504 may be part of any wireless communication network, and may be one of satellite 122, base station 126, or access point 130, for example.

[0098] In Phase 1, the mobile device 105 may detect a request to wirelessly communicate, for example, with the wireless transceiver 504. The request may originate from the mobile device 105 or may originate from the wireless transceiver 504, for example.

[0099] In stage 2, the mobile device 105 may determine whether the SPS receiver is in a tracking state, ie, whether the SPS receiver has acquired and is tracking the SPS. If the SPS receiver is in a tracking state, stages 3-5 may be skipped.

[0100] In phase 3, assuming that the SPS receiver is not in a tracking state, the mobile device 105 begins SPS acquisition, during which the SPS receiver acquires and tracks the SPS signal. The SPS acquisition process may include a timeout, for example, in case the SPS signal cannot be acquired within a reasonable amount of time (e.g., 4 seconds or any desired amount of time).

[0101] In stage 4, mobile device 105 receives SPS signals from SPS SV 502, for example, during SPS acquisition. It should be understood that SPS SV 502 can continuously transmit SPS signals, and once mobile device 105 acquires an SPS signal, tracking can continue.

[0102] In stage 5, once the SPS signal has been acquired by the SPS receiver and is being tracked (or after a timeout period), the mobile device 105 can begin wireless communication with the wireless transceiver 504. As discussed above, if the SPS acquisition times out, the SPS acquisition process can continue after initiating wireless communication before completing SPS acquisition, for example, using SPS signals on an uninterrupted frequency band, or using signal blanking or dwell alignment for SPS signals on an interfered frequency band.

[0103] In stage 6, the mobile device 105 and the wireless transceiver 504 are in wireless communication concurrently with the SPS tracking. The SPS receiver is controlled to mitigate interference caused by the wireless transmission of the mobile device 105. For example, when the mobile device 105 transmits an uplink signal in the interfered frequency band, the SPS receiver can be controlled to perform signal blanking, measurement exclusion, reception inhibition, while continuing to receive the SPS signal. For example, the SPS receiver can use the SPS signal to determine the location of the mobile device 105 while the mobile device 105 is in wireless communication with the wireless transceiver 504.

[0104] At stage 7, the mobile device 105 can determine that the SPS receiver has exited the SPS tracking state, for example, due to a blocking condition that may have prevented the SPS receiver from detecting SPS signals for a period of time.

[0105] At stage 8, the mobile device 105 may suspend any further uplink signal transmissions, or may alternatively drop the wireless communication link.

[0106] In stage 9, the mobile device 105 begins SPS acquisition, during which the SPS receiver acquires and tracks the SPS signal, similar to stage 3. The SPS acquisition process may include a timeout.

[0107] At stage 10, mobile device 105 receives SPS signals from SPS SV 502, for example during SPS acquisition. It should be understood that SPS SV 502 can continuously transmit SPS signals, and once mobile device 105 acquires an SPS signal, it can continue tracking.

[0108] In stage 11, once the SPS receiver has reacquired and is tracking the SPS signal, the mobile device 105 may resume uplink signal transmission, or alternatively re-initiate the wireless communication link.

[0109] In stage 12, the mobile device 105 and the wireless transceiver 504 can again communicate wirelessly concurrently with the SPS tracking. As in stage 6, the SPS receiver can be controlled to mitigate interference caused by the wireless transmission of the mobile device 105. For example, the SPS receiver can use the SPS signals to determine the location of the mobile device 105 while the mobile device 105 is communicating wirelessly with the wireless transceiver 504.

[0110] Figure 6 An example of a transmission activity indicator 600 is illustrated, which can be provided by the wireless transmitter 402 in the mobile device 105 to indicate the start of uplink signal transmission. As shown, the transmission activity indicator 600 can indicate an off duration of wireless communication signal transmission with a low signal and an on duration of wireless communication signal transmission with a high signal. The wireless communication signal transmission can be periodic with a period 602, for example, for satellite communication transmission, the period can be 2.56 seconds, or any other length. Figure 6 The figure shows two cycles of wireless communication signal transmission, labeled #1 and #2. Figure 6 As further illustrated, the off-duration may be different from the on-duration. For example, in some implementations, such as for satellite communication transmissions, the off-duration may be 0.56 seconds and the on-duration may be 2.0 seconds, although other durations may be used.

[0111] It should be understood that the transmission activity indicator may have different Figure 6 Other waveforms shown. For example, the transmission activity indicator can simply indicate the start of each cycle, such as the start of the off-duration of the wireless communication signal transmission, with a pulse so that the measured dwell time can be aligned with the off-duration of the wireless communication signal transmission. For example, the SPS receiver may know the duty cycle of the wireless communication signal transmission, and therefore may not need a waveform indicating the transition from the off-duration to the on-duration. In addition, if the wireless transmitter clock and the SPS receiver clock are synchronized, the transmission activity indicator can indicate the start of the off-period of the wireless communication signal transmission for a single cycle, and the SPS receiver can determine the start of each subsequent off-period based on the known duty cycle and the SPS receiver clock.

[0112] In addition to the transmission activity indicator, the duty cycle of the wireless communication signal transmission can also be provided in a separate signal provided to the SPS receiver. In some implementations, the SPS receiver can determine the duty cycle based on the transmission activity indicator itself (e.g., based on the off duration and the on duration in the first period). In other implementations, the mobile device 105 can be pre-configured with the duty cycle of the wireless communication signal transmission, which can be stored in a memory.

[0113] During the transmission off period 604 in cycle #1, the SPS receiver 406 can perform measurements on the band 1 signal received on the band 1 Rx input, for example, at the configured measurement dwell time. The measurement dwell time can be constrained based on the off period 604 and can be aligned with the off period 604 so that the SPS signal is not measured during the on period 606. The measurement dwell time can start later than the start of the off period 604 to align the dwell time with the received SPS signal. For example, in the case of GPS L1, the dwell should be aligned with the 20 millisecond bit period, which may be slightly different for each satellite. For other signal types using pilot signals, all dwell times can be more closely aligned with the start of the off period. In some implementations, the SPS signal data measured during the period 604 can be stored in a memory for later processing. In another implementation, the measurement dwell time may not be pre-configured, but the SPS receiver can measure the SPS signal until the transmission activity indicator 600 turns high, indicating the on period of the wireless communication signal. The SPS receiver may eliminate or ignore the last coherent integration interval or any coherent integration interval that coincides with the transition of the transmission activity indicator to high. In another implementation, the SPS receiver 406 may configure the measurement dwell time to include the band 1 signal before or after the off period 604. The SPS receiver 406 may perform signal blanking on the band 1 signal received before or after the off period 604 (e.g., during the on period 606). The SPS receiver 406 may include the blanked signal in the measurement operation, wherein the blanked signal does not substantially contribute to the measurement result, and report a timestamp associated with the measurement that effectively aligns the measurement dwell time with the off period 604. In some implementations, for example, for a semi-autonomous or autonomous vehicle, multiple measurement dwells may be performed during the period 604 to obtain multiple position calculations.

[0114] During the transmission of the communication signal on period 606 in cycle #1, the Band 1 signal received on the Band 1 Rx input is ignored and not processed by the SPS receiver 406. If the SPS signal data measured during period 604 is stored in memory, the SPS signal data may be processed during period 606. For example, the SPS signal data stored in memory may be played back to the correlator hardware in the measurement engine 408 so that the measurement process may be performed while the wireless transmitter is active. This optimizes the use of correlators and other hardware resources at the expense of memory used for signal storage.

[0115] During the transmission off period 608 in cycle #2, the SPS receiver 406 may perform measurements on the Band 1 signal received on the Band 1 Rx input within the configured measurement dwell time. Similar to period 604, the measurement dwell time may be configured to be equal to or less than the off period 608 and aligned with the off period 608 so that the SPS signal is not measured during the on period 610. In some implementations, the SPS signal data measured during period 604 may be stored in memory for later processing. In addition, the SPS receiver 406 may perform non-coherent integration during period 608 using the SPS signal measurements from period 604. In some implementations, for example, for semi-autonomous or autonomous vehicles, multiple measurement dwells may be performed during period 608 to obtain multiple position calculations.

[0116] During the signal transmission at period 610 in cycle #2, the SPS receiver 406 may ignore the Band 1 signal received at the Band 1 Rx input and not process it. If the SPS signal data measured during period 608 is stored in memory, the SPS signal data may be processed, for example, played back to the correlator hardware, so that the measurement process may be performed while the wireless transmitter is active.

[0117] This process may continue until the wireless communication signal transmission ceases.

[0118] Band 1 signals that are interfered with by wireless communication signal transmissions may be more suitable for signal acquisition than Band 2 signals that are not interfered with by signal transmissions. Accordingly, Band 1 signals received using a measurement dwell time aligned with the off period of wireless communication signal transmissions may be used for the acquisition process. Band 2 signals may be ignored during signal acquisition or may be used for decoding time. Once the signal acquisition process is complete, both Band 1 and Band 2 signals may be used for SPS tracking, for example, for Band 1 signals, continuing to use a measurement dwell time aligned with the off period of wireless communication signal transmissions.

[0119] Fig. 7A and 7B Different measurement dwell alignments relative to the off period of the wireless transmitter are illustrated. Fig. 7A and 7B Both illustrate a portion of a transmission activity indicator 700 that indicates an OFF duration of wireless communication signal transmission with a low signal and indicates an ON duration of wireless communication signal transmission with a high signal. Fig. 7A and 7B Also illustrated are measurement dwell times 710 and 720, respectively.

[0120] Fig. 7AThe measurement dwell time 710 is illustrated as being substantially aligned with the off-duration of the wireless transmitter, i.e., the measurement dwell time 710 is limited to the off-duration and does not include any portion of the on-duration. However, it should be understood that the measurement dwell time 710 may begin after the off-duration begins and may end before the off-duration ends. The SPS receiver 406 may include a timestamp indicating the applicability time of each measurement dwell. Because the measurement dwell time 710 does not include a portion of the on-duration of the wireless transmitter, the applicability time of the measurement dwell is the middle 712 of the measurement dwell time 710.

[0121] on the other hand, Figure 7B The measurement dwell time 720 is illustrated, which is effectively aligned with the off-duration of the wireless transmitter. Figure 7B As shown, the measurement dwell time 720 may extend into at least a portion of the on-duration of the wireless transmitter, for example, after or before the off-duration. The SPS receiver 406 may blank the signal received during the on-duration of the wireless transmitter, as indicated by a portion 722 of the measurement dwell time 720. The SPS receiver 406 may include the blanked signal in the measurement operation, which does not contribute substantially to the measurement result because the signal is blanked. However, as shown, the middle 724 of the measurement dwell time 720 is not an accurate representation of the applicability time of the measurement dwell time 720, because the middle 724 is based on a portion 722 of the measurement dwell time 720, which does not contribute to the measurement result. Accordingly, the SPS receiver 406 may assign an applicability time 726 based on the off-duration of the wireless signal transmission to the measurement result. Thus, by reporting a measurement timestamp of a measurement operation based on the off-duration of the uplink signal transmission, the measurement dwell time can be effectively aligned with the off-duration of the uplink signal transmission.

[0122] It should be understood that in some cases, there may be a delay or error in the determined on / off time of the uplink signal transmission, resulting in the measurement dwell time 710 or 720 being slightly longer than the uplink transmission on time, and / or resulting in a small portion of the interfered signal not being blanked. This may result in some degradation of performance, depending on how many interfered signals are actually used for measurement, but if the extension of the measurement dwell time 710 or 720 to the uplink transmission on time is small, the degradation of performance may be within the desired tolerance. Accordingly, the measurement dwell time 710 (or 720) can be longer than the uplink transmission on time, and / or can be aligned (or effectively aligned) with the off duration of the uplink signal transmission, so that, for example, if the degradation of performance is within the desired tolerance, the measurement dwell time 710 (or 720) extends slightly into (before and / or after) at least a portion of the on duration of the wireless transmitter.

[0123] Figure 8 8 is a flow chart illustrating a multi-band SPS process 800 performed concurrently with wireless transmissions, including acquisition and tracking. As discussed above, during both acquisition and tracking, SPS signals are received in a first frequency band (Band 1) using a measurement dwell time aligned with an off-duration of wireless communication signal transmissions. In some implementations, Band 2 signals may be received during an on-duration or both an on-duration and an off-duration of wireless communication signal transmissions and used for one or more acquisition operations.

[0124] At block 802 , the mobile device 105 engages in wireless communication with a wireless transceiver, such as one of a satellite 122 , a base station 126 , an access point 130 , a peer device, or the like.

[0125] At decision 804, the mobile device 105 determines whether the SPS receiver is performing SPS tracking, i.e., whether it is in a tracking state. If the SPS receiver is already in a tracking state, signal acquisition is not necessary, and the process can flow to box 816. If the SPS receiver is not in a tracking state, the mobile device 105 begins the acquisition phase. For example, acquisition involves identifying satellites that are visible to the SPS receiver and can be used to provide navigation information. In addition to using the measured dwell time aligned with the off duration of the wireless communication signal transmission as discussed above, a traditional signal acquisition process can also be used.

[0126] At block 806, an initial acquisition is performed using an SPS signal received in a first frequency band (Band 1) (e.g., an SPS signal received at the Band 1 Rx input of the SPS receiver 406 shown in FIG. 3). The Band 1 signal may be acquired using a relatively large correlation window in the frequency and time domains with a relatively high probability of false alarm (Pfa). The correlation window depends on the time and frequency uncertainties. The initial acquisition may be performed during a first set of one or more consecutive off periods of wireless communication signal transmission.

[0127] In block 808, a validation of the signal acquired in block 806 may be performed. The validation of the band 1 signal uses a relatively small search window in the frequency domain and time domain with a relatively low Pfa. The validation measurement operation has a detection threshold with a smaller probability of false detection (Pfa) and a smaller correlation window than the measurement operation used for acquisition in block 806. The validation operation may also have a longer non-coherent integration period than used in the initial acquisition. The validation may be performed during a second set of one or more consecutive off periods of wireless communication signal transmission. In some implementations, for example, where multiple measurement dwells are included within a single off duration of wireless transmission, the validation operation may be performed in the same off duration as the initial acquisition performed in block 806. If the initial acquisition at block 806 has the desired Pfa, the signal validation at block 808 may be skipped.

[0128] At block 810, after the validation operation, the SPS receiver may use the Band 1 signal in one or more subsequent wireless transmitter off periods to perform at least one of bit edge detection or auxiliary code synchronization operations, or a combination thereof. Non-coherent integration may be used to combine the results from more than one off period. If the time uncertainty is below a threshold, block 810 may be skipped and the process may proceed to block 816.

[0129] At block 812, the SPS receiver may begin tracking SPS signals on both Band 1 and Band 2, i.e., Band 2 being a frequency band that is not interfered with by wireless communication signal transmissions and that may be received at the Band 2Rx input of the SPS receiver 406. For example, the SPS receiver may use acquisition results from the Band 1 signal to initiate a tracking process for the Band 2 signal that is interfered with by the wireless transmitter. Due to the time uncertainty, tracking of the SPS signals on both Band 1 and Band 2 may continue using a relatively large search space. Tracking of the Band 1 signal uses a measurement dwell time that is aligned with the off duration of the wireless communication signal transmission, while tracking of the Band 2 signal may operate continuously, i.e., during both the off and on durations of the wireless communication signal transmission.

[0130] In block 814, the Band 2 data signal may be continuously received during the on and off periods of the wireless transmitter and may be synchronized to the broadcast data stream and the time parameters in the SPS signal may be decoded. For example, the Band 2 data signal may be used to decode the time of week (TOW) parameter broadcast by a GPS satellite. Knowledge of the time parameter allows the SPS receiver to reduce the time uncertainty and shrink the search space used to track both the Band 1 signal and the Band 2 signal. At this stage, the SPS receiver may exit the acquisition state. If the time uncertainty is below a threshold, block 814 may be skipped and the process may proceed to block 816 without waiting for the decoding of the time parameter.

[0131] At block 816, the SPS receiver enters a tracking state, during which both Band 1 and Band 2 may be tracked using a relatively small search space. Tracking of Band 1 signals uses a measurement dwell time aligned with the off duration of the wireless communication signal transmission, while tracking of Band 2 signals may operate continuously, i.e., during both the off and on durations of the wireless communication signal transmission. In some implementations, tracking of Band 2 signals may be performed only during the on duration of the wireless communication signal transmission, and the SPS receiver may switch to tracking Band 1 signals during the off duration of the wireless communication signal transmission. If the SPS receiver exits the tracking state, e.g., due to a failure to receive an SPS signal for a period of time (e.g., due to a blocking condition), the SPS receiver may re-enter the acquisition state.

[0132] Fig. 9 A flow chart of an exemplary method 900 for supporting concurrent operation of wireless communications and satellite positioning system (SPS) tracking performed by a mobile device, such as mobile device 105, is shown.

[0133] At block 902, a mobile device detects a request to initiate a wireless communication link with a wireless transceiver in a wireless communication network, e.g., as in Figure 3A Box 302 and Figure 5 For example, a request to initiate wireless communication may be received, for example, from the mobile device 105 or an external entity.

[0134] At block 904, the mobile device may determine whether a satellite positioning system (SPS) signal has been acquired for tracking, e.g., as in Figure 3A Box 304 and Figure 5 At block 906, if it is determined that a satellite positioning system (SPS) signal has not been acquired, an SPS receiver is used to acquire an SPS signal for tracking, wherein the SPS signal has multiple frequency bands, such as in Figure 3A Box 306 in and Figure 5 If it is determined that the SPS has been acquired, block 906 may not be performed. At block 908, a wireless communication link is initiated with the wireless transceiver, wherein transmission of an uplink signal on the wireless communication link interferes with at least one of the plurality of frequency bands in the SPS signal, e.g., as in Figure 3A Box 310 and Figure 5 At block 910, the mobile device concurrently performs wireless communications on a wireless communications link with a wireless transceiver and tracks SPS signals, including controlling the SPS receiver to mitigate interference of transmission of uplink signals on the wireless communications link with at least one of a plurality of frequency bands in the SPS signal, for example, as in Figure 3ABox 310 and Figure 5 as discussed in Stage 6 of

[0135] In one implementation, the request to initiate a wireless communication link may originate from a mobile device, for example, as in Figure 3A Box 302 and Figure 5 In another implementation, the request to initiate a wireless communication link may originate from a wireless transceiver, for example, as in Figure 3A Box 302 and Figure 5 As discussed in Phase 1 of

[0136] In one implementation, when it is determined that the SPS signal has been acquired, acquiring the SPS signal for tracking is not performed, for example, as in Figure 3A Box 302 and Figure 5 As discussed in Phase 1 of

[0137] In one implementation, an SPS signal for tracking may be acquired by executing an SPS acquisition process that has timed out before completion, and completing the SPS acquisition process using an SPS signal in a first frequency band that is interfered with by transmission of an uplink signal after initiating a wireless communication link (wherein only an SPS signal received when no uplink signal is transmitted is used for acquisition), or using an SPS signal in a second frequency band that is not interfered with by transmission of an uplink signal, for example, as in Figure 3A Information from the SPS acquisition process before the SPS acquisition process timeout can be used to initiate the SPS acquisition process after the wireless communication link is initiated, for example, as discussed in block 312 of FIG. Figure 3A As discussed at box 312 in .

[0138] In one implementation, the SPS receiver may be controlled to blank the SPS signal in at least one of the multiple frequency bands received while transmitting the uplink signal on the wireless communication link to mitigate interference, for example, as in Figure 3A Box 310 and Figure 5 as discussed in Stage 6 of

[0139] In one implementation, the SPS receiver may be controlled to exclude from the position calculation an SPS signal in at least one of the multiple frequency bands received when transmitting an uplink signal on the wireless communication link to mitigate interference, for example, as in Figure 3A Box 310 and Figure 5 as discussed in Stage 6 of

[0140] In one implementation, the SPS receiver may be controlled to prohibit reception of SPS signals in at least one of the multiple frequency bands while transmitting an uplink signal on the wireless communication link to mitigate interference, for example, Figure 3A Box 310 and Figure 5 as discussed in Stage 6 of

[0141] In one implementation, the plurality of frequency bands may include a first frequency band interfered by transmission of an uplink signal and a second frequency band not interfered by transmission of an uplink signal, wherein the first frequency band is used to acquire an SPS signal for tracking by an SPS receiver, and the second frequency band is used to perform tracking, e.g., as in Figure 2 , Figure 3A Boxes 306 and 310 in and Figure 5 For example, the first frequency band may be the L1 band, and the second frequency band may include one or more of the L2 band and the L5 band, for example, as described in Figure 2 discussed at the place.

[0142] In one implementation, at least one of the multiple frequency bands interfered by the transmission of the uplink signal may be, for example, Figure 2 At least one of the Galileo E1 signal, BeiDou (BDS) B1 signal, BDS B1C signal, Global Navigation Satellite System (GLONASS) G1 signal, GLONASS L1OC signal, Global Positioning System (GPS) L1, and GPS L1C signal discussed herein.

[0143] In one implementation, the mobile device may determine that the SPS receiver has exited the tracking state and is not tracking an SPS signal, e.g., Figure 3B Box 324 in and Figure 3C Box 344 and Figure 5 The mobile device may stop transmission of uplink signals on the wireless communication link, for example, as in Figure 3B Box 326 and Figure 3C Box 346 and Figure 5 When the transmission of the uplink signal is stopped, the SPS signal used for tracking can be reacquired, for example, as in Figure 3B Box 328 and Figure 3A Box 306 and Figure 5 After reacquiring the SPS signal, the mobile device 105 may begin transmission of an uplink signal over the wireless communication link, e.g., as in Figure 3B Frame 330, Figure 3A Box 310 in and Figure 5For example, stopping transmission of the uplink signal may include abandoning the wireless communication link, and starting transmission of the uplink signal on the wireless communication link after reacquiring the SPS signal may include re-initiating the wireless communication link, for example, as in Figure 3C Box 346 and Figure 3A Box 310 in and Figure 5 Stages 8 and 11 are discussed in this document.

[0144] In one implementation, the wireless transceiver may be a satellite vehicle in a satellite communication system, such as Figure 1 The diagram and Figure 5 In another implementation, the wireless transceiver may be a terrestrial base station in a radio access technology (RAT), such as Figure 1 The diagram and Figure 5 discussed.

[0145] Fig.10 A flow chart of an exemplary method 1000 for supporting concurrent execution of wireless communications and satellite positioning system (SPS) operations performed by a mobile device, such as mobile device 105, is shown.

[0146] At block 1002, a mobile device determines the start, on-duration, and off-duration of uplink signal transmission to a wireless transceiver over a wireless communication link, wherein, for example, Figure 4 and Figure 6 As discussed in , the transmission of uplink signals on the wireless communication link interferes with at least one of the multiple frequency bands received by the SPS receiver. Figure 4 The wireless transmitter 402 in the SPS receiver 406 receives the signal and Figure 6 The transmission activity indicator signal discussed in the specification is used to determine the start, on-duration and off-duration of uplink signal transmission.

[0147] At block 1004, a measurement dwell time is determined based on the off-duration of uplink signal transmission, e.g., Figure 4 and Figure 6 For example, the SPS receiver 406 may configure the measurement dwell time to be equal to or less than the off-duration of the wireless communication signal transmission determined based on the transmission activity indicator signal, e.g. Figure 4 and 6 As discussed in Fig. 7A In another example, the SPS receiver 406 may configure the measurement dwell time to be greater than the off-duration of the wireless communication signal transmission, such as Figure 4The measurement dwell time may be a total integration time based on the product of the coherent integration interval and the number of incoherents, and the number of coherents may be selected to produce a total integration time that is equal to or less than the off duration.

[0148] At block 1006, SPS signal acquisition or SPS signal tracking is performed using SPS signals received by the SPS receiver in a first frequency band during a measurement dwell time aligned with an OFF-duration of uplink signal transmission, and not using SPS signals received by the SPS receiver in the first frequency band during an ON-duration of uplink signal transmission, wherein the first frequency band is interfered by transmission of the uplink signal, e.g., as Figure 4 In and reference Figure 6 As discussed above with respect to the off-duration periods 604, 608 and on-duration periods 606 and 610 in FIG.

[0149] In one implementation, an SPS signal received by an SPS receiver in a first frequency band during an on-duration of an uplink signal transmission is blanked, and the SPS signal received during the off-duration and the blanked SPS signal received during the on-duration are used in a measurement operation, and wherein a measurement dwell time is effectively aligned with the off-duration of the uplink signal transmission by reporting a measurement timestamp of the measurement operation based on the off-duration of the uplink signal transmission, e.g., as Figure 4 , 6 , 7A and 7B.

[0150] In one implementation, the amount of measurement dwell time extends into the on-duration of the uplink signal during which the SPS signal received by the SPS receiver in the first frequency band is not blanked, and the amount of measurement dwell time extending into the on-duration of the uplink signal is constrained based on a desired tolerance for performance of SPS signal acquisition or SPS signal tracking, for example, as described with reference to Fig. 7A and 7B discussed.

[0151] In one implementation, the measurement dwell time may be constrained to be less than or equal to the off-duration of uplink signal transmission, e.g. Fig. 7A The measurement dwell time may be the total integration time as the product of the coherent integration interval and the number of incoherents, e.g. Figure 4 and 6 For example, the measurement dwell time can be constrained by adjusting the amount of incoherence based on the off-duration of the uplink signal transmission, e.g. Figure 6 discussed in .

[0152] In one implementation, performing SPS signal acquisition or tracking using SPS signals received in a first frequency band may include measuring, by the SPS receiver, a plurality of measurement dwell times within a single off-duration of uplink signal transmission, e.g., Figure 4 Reference Figure 6 As discussed in the off-duration periods 604, 608 in FIG.
