Description

Technical Field

[0001] One or more embodiments disclosed herein relate generally to electronic devices and methods of operating the same, and more particularly to techniques for adjusting a peak voltage of a signal transmitted via ultra-wideband (UWB) communications. Background Art

[0002] Various electronic devices such as smart phones, tablet PCs, portable multimedia players (PMPs), personal digital assistants (PDAs), laptop personal computers, and wearable devices have become increasingly popular.

[0003] Recently, progress has been made in technologies that support ultra-wideband (UWB) communications for these electronic devices. For example, technologies have been developed for measuring the location of electronic devices through UWB communications between electronic devices and using the measured locations to provide various services (e.g., authentication services). UWB communications can use a wider bandwidth than other communication schemes. Position measurement services using UWB communications can have a smaller error rate than, for example, GPS position measurement services.

[0004] Communication frequency management agencies around the world have imposed restrictions on the characteristics of UWB signals. For example, the Federal Communications Commission (FCC) in the United States limits the maximum average power of UWB signals to -41.3dBm / MHz and the peak power to 0dBm / MHz.

[0005] The above information is presented as background information only to assist with understanding the present disclosure. No determination has been made and no assertion has been made as to whether any of the above techniques might be applicable as prior art with respect to the present disclosure. Summary of the invention

[0006] In order to comply with the above-mentioned limitations of UWB communication, the signal transmitted by UWB communication may be maintained at a constant strength. However, if the peak voltage of the signal remains constant even when the peak voltage can be increased, the transmission quality of the signal may not be improved.

[0007] The electronic device according to the embodiment includes: a first communication circuit configured to perform a first communication using an ultra-wideband (UWB) communication scheme; and a processor. The processor can control the communication circuit to: identify a frame length of the data to be sent based on the characteristics of the data to be sent using the first communication circuit; determine a peak voltage of a signal containing the data to be sent based on the identified frame length; and send the data using the signal with the determined peak voltage.

[0008] According to an embodiment, an operating method of an electronic device may include: generating data to be sent using a first communication circuit, wherein the first communication circuit is configured to perform a first communication using an ultra-wideband (UWB) communication scheme; identifying a frame length of the generated data; based on the identified frame length, determining a peak voltage of a signal containing the data to be sent; and sending the data using a signal having the determined peak voltage.

[0009] Additional aspects will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the presented embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The sensor module 176 may detect an operating state (e.g., power or temperature) of the electronic device 101 or an environmental state (e.g., a state of a user) outside the electronic device 101, and then generate an electrical signal or data value corresponding to the detected state.

The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with an external electronic device via a first network 198 (e.g., a short-range communication network such as Bluetooth, Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (e.g., a long-range communication network such as a cellular network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip), or these various types of communication modules can be implemented as multiple components separated from each other (e.g., multiple chips). The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199) using user information (e.g., an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

A signal or power may then be transmitted or received between the communication module 190 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as a part of the antenna module 197.

[0043] At least some of the above components may be connected to each other via an inter-peripheral communication scheme (e.g., a bus, a general purpose input output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)) and communicatively transmit signals (e.g., commands or data) therebetween.

[0044] According to an embodiment, a command or data may be sent or received between the electronic device 101 and the external electronic device 104 via the server 108 connected to the second network 199. Each of the electronic device 102 and the electronic device 104 may be a device of the same type as the electronic device 101, or a device of a different type from the electronic device 101. According to an embodiment, all or some operations to be executed in the electronic device 101 may be executed in one or more of the external electronic device 102, the external electronic device 104, or the server 108.

[0053] Figure 3 is a block diagram of an electronic device according to an embodiment.

[0054] Reference Figure 3 According to the electronic device 300 (eg Figure 1 The electronic device 101 in the embodiment may include an antenna 310 (eg Figure 1 Antenna module 197 in), communication circuit 320 (e.g. Figure 1 The communication module 190 in FIG. 1 and the processor 330 (eg Figure 1 120 in ). Processor 330 may include a microprocessor or any suitable type of processing circuit, such as one or more general-purpose processors (e.g., ARM-based processors), digital signal processors (DSPs), programmable logic devices (PLDs), application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), graphics processing units (GPUs), video card controllers, etc. In addition, it should be recognized that when a general-purpose computer accesses the code for implementing the processing shown herein, the execution of the code converts the general-purpose computer into a special-purpose computer for performing the processing shown herein. Certain functions and steps provided in the accompanying drawings may be implemented in hardware, software, or a combination of both, and may be executed in whole or in part within the programming instructions of a computer. In addition, the skilled person should understand and appreciate that a "processor" or "microprocessor" may be hardware in the disclosure claimed for protection.

[0055] According to an embodiment, antenna 310 can use various communication standards to send or receive signals. One such communication standard can be ultra-wideband or UWB communication. UWB communication can also refer to several different communication methods for sending information with relatively low power by using a wider frequency band (e.g., a frequency band of 3.1 GHz to 10 GHz) than other communication methods.

[0056] According to an embodiment, the electronic device 300 may use the UWB signal output or received by the antenna 310 to obtain the location information of an external electronic device (not shown) that transmits and receives UWB data. When the electronic device 300 obtains the location information of the external electronic device through UWB communication, the location information of the external electronic device may be more accurate relative to other methods of obtaining location information. For example, the actual location error of the external electronic device obtained through UWB may be in the order of centimeters.

[0057] According to an embodiment, the communication circuit 320 is electrically connected to the processor 330 and may transmit a signal received through the antenna 310 to the processor 330. The communication circuit 320 is electrically connected to the antenna 310 and may transmit a signal including data to be transmitted through UWB communication to the antenna 310.

[0058] According to an embodiment, the characteristics of the UWB signal can be adjusted by the standards established by the FCC of the United States. For example, the FCC has defined the maximum average power of the UWB signal as -41.3dBm / MHz, and the peak power as 0dBm / MHz. The UWB signal must meet the maximum average power and peak power defined by the FCC. The UWB signal is usually transmitted with a relatively low power than the signal of other communication methods. In view of this, conventionally the UWB signal can be sent with a constant peak voltage to solve the worst-case scenario in which the transmission or reception of the signal may be difficult, for example, the transmission is blocked due to the shielding of the electronic device outputting the UWB signal by a container such as a handbag. The constant peak voltage can be determined to be close to the maximum average power and peak power specified by the FCC. However, conventional technology also maintains a constant peak power amplitude. Since conventional technology keeps the peak voltage of the signal constant even when the peak voltage may be increased, conventional technology may not increase the transmission quality of the signal.

[0059] Hereinafter, the output of a UWB signal when the signal peak voltage is changed so as to adapt to a specific situation will be described.

[0060] According to an embodiment, the processor 330 may identify the frame length of the data to be transmitted based on the characteristics of the data to be transmitted. The frame length may refer to the difference between the data transmission start time and the data transmission completion time.

[0061] According to an embodiment, the data to be transmitted may be generated by the processor 330 according to a standard (e.g., 802.15.4) defined by the Institute of Electrical and Electronics Engineers (IEEE). The data may include one or more of various fields such as: synchronization data (SYNC) for time synchronization between the electronic device 300 performing transmission and an external electronic device (not shown) performing reception, a physical payload (PHY) including data to be transmitted, a PHY header (PHR) representing a header portion of the PHY, a frame start delimiter (SFD) indicating the end of the SYNC and the beginning of the PHR, and a scrambled timestamp security (STS) configured to prevent attacks (e.g., relay attacks) on the data.

[0062] According to an embodiment, information related to data to be transmitted may be received from an external electronic device (for example, Fig. 7AThe characteristics of the data to be transmitted may be identified when the UWB parameters exchanged in operation 721 are received. According to another embodiment, the characteristics of the data to be transmitted may be identified when the data is generated.

[0063] According to an embodiment, the processor 330 may identify the frame length based on the characteristics of the data to be transmitted. Figure 4A and Figure 4B A detailed example for identifying the frame length is described.

[0064] According to an embodiment, the processor 330 may determine the peak voltage of the signal based on the identified frame length. The signal may include data to be sent. The processor 330 may increase the peak voltage of the signal as the identified frame length decreases. This is because the signal output time decreases when the frame length decreases, so even if the peak voltage increases, the pre-configured condition (e.g., the maximum average power defined by the FCC) may be met.

[0065] According to an embodiment, the processor 330 may determine the peak voltage so that the average power of the signal does not exceed a preconfigured value (e.g., a maximum average power defined by the FCC). According to another embodiment, the processor 330 may determine the peak voltage so that the maximum output power of the signal does not exceed a preconfigured value (e.g., a peak power defined by the FCC).

[0066] According to an embodiment, the processor 330 can adaptively adjust the peak voltage of the signal according to the frame length, so that the peak voltage of the signal can be dynamically increased, thereby increasing the transmission quality and maximum reach of the signal.

[0085] According to an embodiment, the length of the PHR 415, 427, or 435 may be determined by Equation 3.

[0086] [Equation 3]

[0089] According to an embodiment, the length of PHY 417, 429 or 437 may be determined by Equation 4.

[0090] [Equation 4]

[0091] PHY payload = data size (bytes) * 8 / data_rate

[0092] Wherein, data_size is the data size of PHY; and data_rate is the transmission rate of PHY.

[0093] According to an embodiment, the length of the STS 425, 439, or 445 may be determined by Equation 5.

[0094] [Equation 5]

[0095] STS = STS length * 512 * pulse width + (NSEG + 1) * 512 * pulse width

NSEG in Equation 5 may refer to the number of gaps, and the number of gaps may be one more than the number of STS activities 453 and 457.

[0099] According to an embodiment, the processor 330 may use the above equation to determine the frame length of the elements included in the data, and may determine the sum of the frame lengths of the elements as the frame length of the data. Hereinafter, a detailed embodiment of determining the peak voltage of a signal based on the frame length will be described.

[0100] According to an embodiment, the processor 330 may determine the first voltage based on the identified frame length and a maximum allowed average power of the signal (eg, a maximum average power defined by the FCC).

[0101] According to an embodiment, the frame length related parameter (L burst ), maximum average power (P avg ), tolerance voltage (R margin ), antenna load impedance (Z 0 ), pulse repetition frequency (hereinafter referred to as “PRF”), resolution bandwidth (hereinafter referred to as “RBW”), and effective single pulse width (τ c ) to determine the first voltage. For example, the first voltage may be determined based on Equation 6. The first voltage may be a voltage associated with the maximum allowed average power.

[0102] [Equation 6]

[0103]

[0104] According to an embodiment, the effective single pulse width may be determined based on Equation 7.

[0105] [Equation 7]

[0106]

[0107] where p(t) is the function corresponding to the pulse envelope; V pk is the peak voltage of the signal; t c is a time interval that depends on the signal energy (for example, if the signal has a frequency of 499.2 MHz, t c is 2.0032ns, if the signal has a frequency of 1081.6MHz, tc is 0.9246ns, if the signal has a frequency of 1331.2MHz, t c is 0.7512ns, and if the signal has a frequency of 1354.97MHz, t c is 0.7380ns).

[0108] According to an embodiment, the frame length related parameter (L burst ) may vary based on a comparison between the frame length and a preconfigured value. For example, when the frame length is 1 ms or shorter, the frame length related parameter (L burst ) can be configured as 1 ms / frame length. In another example, when the frame length is 1 ms or longer, the frame length related parameter (L burst ) may be configured as a value of 1. Therefore, the first voltage may decrease as the frame length increases.

[0109] According to an embodiment, the processor 330 may determine the second voltage based on a maximum allowed peak voltage of the signal (eg, a peak voltage defined by the FCC).

[0110] According to one embodiment, the maximum peak power (P pk ), tolerance voltage (R margin ), antenna load impedance (Z 0 ), pulse desensitization correction factor (α b ) and antenna gain (G ant ) to determine the second voltage. For example, the second voltage may be determined based on Equation 8. The second voltage may be a voltage related to the maximum allowable peak voltage.

[0111] [Equation 8]

[0112]

[0113] Will refer to it later Figure 5A , Figure 5B and Figure 5C Describes the pulse desensitization correction factor.

[0114] According to an embodiment, the processor 330 may determine which of the first voltage or the second voltage is lower, and use the lower voltage as the peak voltage of the signal, as shown in Equation 9.

[0115] [Equation 9]

[0116]

[0117] Referring to Equation 9, the lower of the first voltage and the second voltage may be determined as the peak voltage. The processor 330 may determine the lower of the first voltage and the second voltage as the peak voltage, and thus may adjust the peak voltage based on the data length to simultaneously meet the maximum allowable average power and the maximum allowable peak power specified by the FCC.

[0118] Referring to Equation 6 and Equation 9, when the pulse repetition frequency increases, the processor 330 may reduce the peak voltage. When the pulse repetition frequency decreases, the processor 330 may increase the peak voltage.

[0119] Referring to Equation 6 and Equation 9, when the frame length increases, the processor 330 may reduce the peak voltage. When the frame length decreases, the processor 330 may increase the peak voltage.

[0120] Figure 5A An embodiment of determining a pulse desensitization correction factor used as a parameter for determining a peak voltage in an electronic device according to an embodiment is shown, Figure 5BAn embodiment of determining a pulse desensitization correction factor used as a parameter for determining a peak voltage in an electronic device according to another embodiment is shown, and Figure 5C An embodiment of determining a pulse desensitization correction factor used as a parameter for determining a peak voltage in an electronic device according to still another embodiment is shown.

[0121] According to an embodiment, the pulse desensitization correction factor (α b ).

[0122] [Equation 10]

[0123]

[0124] Where Q is a one-dimensional Gaussian function; τ b is effectively multiple pulse widths.

[0125] The effective multi-pulse width (τ) included in Equation 10 can be calculated using Equation 11. b ).

[0126] [Equation 11]

[0127]

[0128] Among them, P b,max (t) is the burst shape corresponding to the burst-scrambling code and the maximum peak power; and t b It includes burst p b (t) is the time interval of all energies.

[0129] According to an embodiment, t can be determined by multiplying the pulse width by the number of pulses within 20 ns. b .

[0130] For example, refer to Figure 5A , which shows a data symbol with a pulse repetition frequency of 124.8 MHz, a segment 511 may correspond to an area of ​​2 ns. A duration of 20 ns may correspond to ten segments 510. Five pulses may be included in the ten segments. b Determined to be 10 ns, which is obtained by multiplying the pulse width (2 ns) by the number of pulses (5).

[0131] In another example, refer to Figure 5B , which shows a data symbol with a pulse repetition frequency of 249.6 MHz, a segment 521 may correspond to an area of ​​2 ns. A duration of 20 ns may correspond to ten segments 520. Six pulses may be included in the ten segments. bcan be determined to be 12ns, which is obtained by multiplying the pulse width (2ns) by the number of pulses (6).

[0132] In another example, refer to Figure 5C , which shows a data symbol with a pulse repetition frequency of 15.6 MHz, one cycle 531 may correspond to a region of 2 ns. A duration of 20 ns may correspond to ten cycles 530. Ten pulses may be included in the ten cycles. b It can be determined as 20 ns, which is obtained by multiplying the pulse width (2 ns) by the number of pulses (10).

[0133] According to an embodiment, the processor 330 can use the above method to adaptively adjust the peak voltage of the signal according to the frame length. Therefore, the peak voltage of the signal can be dynamically increased to increase the transmission quality and maximum reach of the signal.

[0134] Figure 6 is a graph illustrating a peak voltage determined according to a frame length and a pulse repetition frequency (PRF) in an electronic device according to an embodiment.

[0135] Figure 6 The variation of the peak voltage 620 as the frame length 610 varies is shown.

[0136] According to an embodiment, the processor 330 may reduce the peak voltage 620 as the frame length 610 increases. In one example, when the pulse repetition frequency (PRF) is 124.8 MHz (631), the processor 330 may reduce the peak voltage 620 as the frame length 610 increases. In another example, when the pulse repetition frequency (PRF) is 62.4 MHz (633), the processor 330 may reduce the peak voltage 620 as the frame length 610 increases.

[0137] According to an embodiment, the processor 330 may determine the peak voltage based on a pulse repetition frequency (PRF). When the pulse repetition frequency increases, the processor 330 may reduce the peak voltage. Figure 6 , which shows that the peak voltage decreases when the pulse repetition frequency increases from 62.4 MHz to 124.8 MHz while keeping the frame length 610 constant. On the other hand, it is also shown that the peak voltage increases when the pulse repetition frequency decreases from 124.8 MHz to 62.4 MHz while keeping the frame length 610 constant.

[0138] According to an embodiment, the processor 330 may increase the peak voltage 620 as the frame length 610 decreases. In one example, when the pulse repetition frequency (PRF) is 124.8 MHz (631), the processor 330 may increase the peak voltage 620 as the frame length 610 decreases. In another example, when the pulse repetition frequency (PRF) is 62.4 MHz (633), the processor 330 may increase the peak voltage 620 as the frame length 610 decreases.

[0139] According to an embodiment, at a specific pulse repetition frequency or less, the processor 330 may not increase the peak voltage even if the frame length is reduced to a preconfigured value or less. Even if the frame length is reduced to a preconfigured value or less, in order to prevent the maximum output power or average power of the signal from exceeding the maximum peak power or maximum average power specified by the FCC, the peak voltage will not increase. When the frame length is reduced to a preconfigured value or less at a specific pulse repetition frequency (PRF) or less, the processor 330 may maintain the peak voltage without increasing the peak voltage. For example, referring to Figure 6 In section 635, when the frame length of a signal having a pulse repetition frequency of 62.4 MHz is reduced to 200 μs or less, the peak voltage of the signal can be maintained without increasing it. In order to prevent the maximum output power or average power of the signal from exceeding the maximum peak power or maximum average power specified by the FCC, the peak voltage of the signal is maintained without increasing. The preconfigured value can be changed based on the magnitude of the repetition frequency. For example, the preconfigured frame length value can increase as the repetition frequency decreases.

Various parameters may be used to determine the length of data and may be configured differently according to a pulse repetition frequency (PRF). Figure 7B One embodiment of a table stored in memory 130 is shown.

[0154] According to an embodiment, in operation 727, the electronic device 300 may transmit a polling message to the external electronic device 710 through UWB communication. For example, the polling message transmitted by the electronic device 300 may be transmitted to the first anchor point 711 to the anchor point N 713 through a multicast method. When the external electronic device 710 measures the location information of the electronic device 300, the polling message may be used.

[0155] According to an embodiment, in operation 729, the first anchor point 711 may transmit a response message corresponding to the polling message to the electronic device 300 through UWB communication in response to reception of the polling message.

[0156] According to an embodiment, in operation 731, the anchor point N 713 may transmit a response message corresponding to the polling message to the electronic device 300 through UWB communication in response to reception of the polling message.

[0157] According to an embodiment, in operation 733, the electronic device 300 may transmit a final message to the external electronic device 710 through UWB communication in response to reception of the response message. For example, one or more anchor points (eg, the first anchor point 711 to the anchor point N 713) may receive the final message through a multicast method.

[0158] According to an embodiment, the data transmitted in operations 727 to 733 may be in the form of Figure 4A 4. In the fourth PPDU 440, there is no PHY payload (e.g. Figure 4A PHY payload 417, 429 or 437).

[0159] According to an embodiment, in operation 735, the electronic device 300 may transmit an additional data frame to the external electronic device 710 through UWB communication. For example, one or more anchor points (eg, the first anchor point 711 or the anchor point N 713) may receive the additional data frame through a multicast method.

[0160] The electronic device 300 may transmit a data frame including ranging response time delay (RRTD) or ranging round trip measurement (RRTM) to the external electronic device 710. The external electronic device 710 may determine relative position information between the electronic device 300 and the external electronic device 710 based on the RRTD or RRTM included in the data frame.
