[0046] The aspects, features, and advantages of this disclosure will readily be apparent from the following detailed description, which simply illustrates several specific embodiments and implementations, including the best mode contemplated for carrying out this disclosure. This disclosure is also capable of having other different embodiments and modifications can be made to several details therein in various obvious aspects, all without departing from the spirit and scope of this disclosure. Therefore, the drawings and description should be considered illustrative in nature and not restrictive. In the drawings, this disclosure is illustrated by way of example rather than limitation.

[0047] The following Figures 1 to 4b Various embodiments implemented in wireless communication systems and various embodiments implemented using orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) communication technologies are described. Figures 1 to 3 The description is not intended to impose physical or architectural limitations on the ways in which different embodiments can be implemented. Different embodiments of this disclosure can be implemented in any suitably arranged communication system.

[0048] Figure 1 An example wireless network according to an embodiment of this disclosure is shown. Figure 1 The embodiments of the wireless network shown are for illustrative purposes only. Other embodiments of the wireless network 100 may be used without departing from the scope of this disclosure.

[0049] like Figure 1 As shown, the wireless network includes gNB 101 (e.g., a base station (BS)), gNB 102, and gNB 103. gNB 101 communicates with gNB 102 and gNB 103. gNB 101 also communicates with at least one network 130, such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0050] gNB 102 provides wireless broadband access to network 130 to a first plurality of user equipments (UEs) within its coverage area 120. The first plurality of UEs includes: UE 111, which may be located in a small business (SB); UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi hotspot (HS); UE 114, which may be located in a first residence (R); UE 115, which may be located in a second residence (R); and UE 116, which may be a mobile device (M), such as a cellular phone, wireless laptop computer, wireless PDA, etc. gNB 103 provides wireless broadband access to network 130 to a second plurality of UEs within its coverage area 125. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of gNBs 101 to 103 may use 5G, LTE, LTE-A, WiMAX, WiFi or other wireless communication technologies to communicate with each other and with UEs 111 to 116.

[0051] Depending on the network type, the term "base station" or "BS" can refer to any component (or set of components) configured to provide wireless access to a network, such as a transmitting point (TP), a transmitting-receiving point (TRP), an enhanced base station (eNodeB or eNB), a 5G base station (gNB), a macro cell, a femtocell, a WiFi access point (AP), or other equipment supporting wireless functionality. A base station can provide wireless access according to one or more wireless communication protocols, such as 5G 3GPP New Radio Interface / Access (NR), Long Term Evolution (LTE), LTE Advanced (LTE-A), High Speed ​​Packet Access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For convenience, the terms "BS" and "TRP" are used interchangeably in this patent document to refer to network infrastructure components that provide wireless access to remote terminals. Furthermore, depending on the network type, the term "user equipment" or "UE" can refer to any component, such as a "mobile station," "subscriber station," "remote terminal," "wireless terminal," "receiving point," or "user equipment." For convenience, the terms “user equipment” and “UE” are used in this patent document to refer to a remote wireless device that provides wireless access to a BS, whether the UE is a mobile device (such as a mobile phone or smartphone) or is generally considered to be a fixed device (such as a desktop computer or vending machine).

[0052] The dashed lines indicate the approximate extent of coverage areas 120 and 125, which are shown as roughly circular for illustrative and explanatory purposes only. It should be clearly understood that coverage areas associated with the gNB (such as coverage areas 120 and 125) may have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and man-made obstacles.

[0053] As described in more detail below, one or more of UEs 111 to 116 include circuitry, programming, or a combination thereof for data transmission performed in a ranging cycle. In some embodiments, one or more of gNBs 101 to 103 include circuitry, programming, or a combination thereof for data transmission performed in a ranging cycle.

[0054] Although Figure 1 An example of a wireless network is shown, but more can be found on... Figure 1 Various modifications can be made. For example, the wireless network can include any number of gNBs and any number of UEs arranged in any suitable configuration. Furthermore, gNB 101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to network 130. Similarly, each gNB 102 to 103 can communicate directly with network 130 and provide UEs with direct wireless broadband access to network 130. Additionally, gNBs 101, 102, and / or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

[0055] Figure 2 An example gNB 102 according to an embodiment of this disclosure is shown. Figure 2 The embodiment of gNB 102 shown is for illustrative purposes only, and Figure 1 gNBs 101 and 103 can have the same or similar configurations. However, gNBs come in a wide variety of configurations, and Figure 2 This disclosure is not intended to limit the scope to any particular implementation of gNB.

[0056] like Figure 2 As shown, gNB 102 includes multiple antennas 205a to 205n, multiple RF transceivers 210a to 210n, transmit (TX) processing circuitry 215, and receive (RX) processing circuitry 220. gNB 102 also includes a controller / processor 225, a memory 230, and a backhaul or network interface 235.

[0057] RF transceivers 210a to 210n receive incoming RF signals, such as signals transmitted by the UE in network 100, from antennas 205a to 205n. RF transceivers 210a to 210n down-convert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 220, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signals. RX processing circuitry 220 sends the processed baseband signal to controller / processor 225 for further processing.

[0058] TX processing circuit 215 receives analog or digital data (such as voice data, network data, email, or interactive video game data) from controller / processor 225. TX processing circuit 215 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 210a to 210n receive the outgoing processed baseband or IF signal from TX processing circuit 215 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 205a to 205n.

[0059] The controller / processor 225 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 225 may control the RF transceivers 210a to 210n, the RX processing circuitry 220, and the TX processing circuitry 215 to receive forward channel signals and transmit reverse channel signals, based on well-known principles. The controller / processor 225 may also support additional functions, such as more advanced wireless communication capabilities.

[0060] For example, the controller / processor 225 can support beamforming or directional routing operations, where outgoing signals from multiple antennas 205a to 205n are weighted differently to effectively direct the outgoing signals in a desired direction. Any of a variety of other functions can be supported in the gNB 102 via the controller / processor 225.

[0061] The controller / processor 225 is also capable of executing programs and other processes, such as an operating system, residing in the memory 230. The controller / processor 225 can move data into or out of the memory 230 as needed by the executing process.

[0062] The controller / processor 225 is also coupled to a backhaul or network interface 235. The backhaul or network interface 235 allows the gNB 102 to communicate with other devices or systems via a backhaul connection or network. Interface 235 can support communication via any suitable wired or wireless connection. For example, when the gNB 102 is implemented as part of a cellular communication system (such as a system supporting 5G, LTE, or LTE-A), interface 235 can allow the gNB 102 to communicate with other gNBs via a wired or wireless backhaul connection. When the gNB 102 is implemented as an access point, interface 235 can allow the gNB 102 to communicate via a wired or wireless local area network or via a wired or wireless connection to a larger network (such as the Internet). Interface 235 includes any suitable architecture supporting communication via a wired or wireless connection, such as an Ethernet or RF transceiver.

[0063] The memory 230 is coupled to the controller / processor 225. A portion of the memory 230 may include RAM, and another portion of the memory 230 may include flash memory or other ROM.

[0064] Although Figure 2 An example of gNB 102 is shown, but it is possible to compare it with other models. Figure 2 Various changes can be made. For example, gNB 102 can include any number of Figure 2 Each component shown. As a specific example, an access point may include multiple interfaces 235, and the controller / processor 225 may support routing functionality to route data between different network addresses. As another specific example, although shown as a single instance of TX processing circuitry 215 and a single instance of RX processing circuitry 220, the gNB102 may include multiple instances of each (such as one per RF transceiver). Furthermore, Figure 2 The various components can be combined, further subdivided, or omitted, and additional components can be added according to specific needs.

[0065] Figure 3 An example UE 116 according to an embodiment of this disclosure is shown. Figure 3 The embodiment of UE 116 shown is for illustrative purposes only, and Figure 1 UEs 111 to 115 can have the same or similar configurations. However, UEs have a wide variety of configurations, and Figure 3 This disclosure is not intended to limit the scope of any particular implementation of the UE.

[0066] like Figure 3As shown, UE 116 includes an antenna 305, a radio frequency (RF) transceiver 310, a TX processing circuit 315, a microphone 320, and a receive (RX) processing circuit 325. UE 116 also includes a speaker 330, a processor 340, an input / output (I / O) interface (IF) 345, a touchscreen 350, a display 355, and memory 360. Memory 360 includes an operating system (OS) 361 and one or more application programs 362.

[0067] RF transceiver 310 receives incoming RF signals transmitted by a gNB of network 100 from antenna 305. RF transceiver 310 down-converts the incoming RF signals to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to RX processing circuitry 325, which generates a processed baseband signal by filtering, decoding, and / or digitizing the baseband or IF signal. RX processing circuitry 325 sends the processed baseband signal to speaker 330 (e.g., for voice data) or processor 340 (e.g., for web browsing data) for further processing.

[0068] The TX processing circuit 315 receives analog or digital voice data from the microphone 320, or other outgoing baseband data (such as network data, email, or interactive video game data) from the processor 340. The TX processing circuit 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 310 receives the outgoing processed baseband or IF signal from the TX processing circuit 315 and up-converts the baseband or IF signal into an RF signal transmitted via the antenna 305.

[0069] Processor 340 may include one or more processors or other processing devices and executes OS 361 stored in memory 360 to control the overall operation of UE 116. For example, processor 340 may control the RF transceiver 310, RX processing circuitry 325, and TX processing circuitry 315 to receive forward channel signals and transmit reverse channel signals according to well-known principles. In some embodiments, processor 340 includes at least one microprocessor or microcontroller.

[0070] Processor 340 is also capable of executing other processes and programs residing in memory 360, such as processes for data transfer in a ranging loop. Processor 340 can move data into or out of memory 360 as needed for executing processes. In some embodiments, processor 340 is configured to execute application 362 based on OS 361 or in response to signals received from a gNB or operator. Processor 340 is also coupled to I / O interface 345, which provides UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. I / O interface 345 is the communication path between these accessories and processor 340.

[0071] The processor 340 is also connected to the touchscreen 350 and the display 355. The operator of the UE 116 can use the touchscreen 350 to input data into the UE 116. The display 355 may be a liquid crystal display, a light-emitting diode display, or other display capable of rendering (e.g., from a website) text and / or at least limited graphics.

[0072] The memory 360 is coupled to the processor 340. A portion of the memory 360 may include random access memory (RAM), and another portion of the memory 360 may include flash memory or other read-only memory (ROM).

[0073] Although Figure 3 An example of UE 116 is shown, but it is possible to modify it. Figure 3 Make various changes. For example, Figure 3 The various components can be combined, further subdivided, or omitted, and additional components can be added according to specific needs. As a specific example, processor 340 can be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although... Figure 3 The UE 116 is shown configured as a mobile phone or smartphone, but the UE can be configured to operate as other types of mobile or fixed devices.

[0074] Figure 4a This is a high-level diagram of the transmit path circuitry. For example, the transmit path circuitry can be used in Orthogonal Frequency Division Multiple Access (OFDMA) communication. Figure 4b This is a high-level diagram of the receive path circuitry. For example, the receive path circuitry can be used in Orthogonal Frequency Division Multiple Access (OFDMA) communication. Figure 4a and Figure 4b In the context of downlink communication, the transmitting path circuitry can be implemented in the base station (gNB) 102 or a relay station, and the receiving path circuitry can be implemented in the user equipment (e.g., Figure 1The user equipment 116) is implemented in other examples. For uplink communication, the receive path circuit 450 can be implemented in the base station (e.g., Figure 1 This can be implemented in a gNB 102 or a relay station, and the transmission path circuit can be implemented in the user equipment (e.g., Figure 1 Implemented in user equipment 116).

[0075] The transmit path circuitry includes a channel coding and modulation block 405, a serial-to-parallel (SP) conversion block 410, an N-size inverse fast Fourier transform (IFFT) block 415, a parallel-to-serial (PS) conversion block 420, a cyclic prefix addition block 425, and an up-conversion converter (UC) 430. The receive path circuitry includes a down-conversion converter (DC) 455, a cyclic prefix removal block 460, a serial-to-parallel (SP) conversion block 465, an N-size fast Fourier transform (FFT) block 470, a parallel-to-serial (PS) conversion block 475, and a channel decoding and demodulation block 480.

[0076] Figure 4a 400 and Figure 4b At least some of the components in 450 can be implemented in software, while others can be implemented in configurable hardware or a mixture of software and configurable hardware. Specifically, note that the FFT and IFFT blocks described in this disclosure can be implemented as configurable software algorithms, where the value of size N can be modified depending on the implementation.

[0077] Furthermore, while this disclosure pertains to embodiments implementing the Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT), these are merely exemplary and should not be construed as limiting the scope of this disclosure. It will be understood that in alternative embodiments of this disclosure, the FFT and IFFT functions can be readily replaced by Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions, respectively. It will be understood that for the DFT and IDFT functions, the value of variable N can be any integer (i.e., 1, 2, 3, 4, etc.), while for the FFT and IFFT functions, the value of variable N can be any integer that is a power of 2 (i.e., 1, 2, 4, 8, 16, etc.).

[0078] In the transmit path circuit 400, the channel coding and modulation block 405 receives a set of information bits and applies coding (e.g., LDPC coding) and modulation (e.g., Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM)) to the input bits to generate a frequency-domain modulated symbol sequence. The serial-to-parallel conversion block 410 converts (i.e., demultiplexes) the serial modulated symbols into parallel data to generate N parallel symbol streams, where N is the IFFT / FFT size used in BS 102 and UE 116. An IFFT block 415 of size N then performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. A parallel-to-serial block 420 converts (i.e., multiplexes) the parallel time-domain output symbols from the N-size IFFT block 415 to generate a serial time-domain signal. A cyclic prefix addition block 425 then inserts a cyclic prefix into the time-domain signal. Finally, an up-converter 430 modulates (i.e., up-converts) the output of the cyclic prefix addition block 425 to an RF frequency for transmission via the radio channel. The signal can also be filtered at the baseband before being switched to the RF frequency.

[0079] The transmitted RF signal arrives at UE 116 after traversing the wireless channel, and performs the opposite operation to that at gNB 102. Downconverter 455 downconverts the received signal to the baseband frequency, and cyclic prefix removal block 460 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel conversion block 465 converts the time-domain baseband signal into a parallel time-domain signal. An N-sized FFT block 470 then performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial conversion block 475 converts the parallel frequency-domain signals into a sequence of modulated data symbols. Channel decoding and demodulation block 480 demodulates and then decodes the modulated symbols to recover the original input data stream.

[0080] Each of gNBs 101 to 103 can implement a transmission path similar to that used for transmitting to user equipments 111 to 116 in the downlink, and a reception path similar to that used for receiving from user equipments 111 to 116 in the uplink. Similarly, each of user equipments 111 to 116 can implement a transmission path corresponding to the architecture used for transmitting to gNBs 101 to 103 in the uplink, and a reception path corresponding to the architecture used for receiving from gNBs 101 to 103 in the downlink.

[0081] Peer-to-Peer (PAC) sensing networks are fully distributed communication networks that allow direct communication between PAC devices (PDs). Wireless Personal Area Networks (WPANs) or Simple Personal Area Networks (PANs) can also be fully distributed communication networks. WPANs or PANs are communication networks that allow wireless connections between PAN devices (PDs). PAN devices and PAC devices can be used interchangeably because a PAC network is also a PAN network, and vice versa.

[0082] PAC networks can employ various topologies, such as mesh, star, and / or pair-to-pair, to support interactions between PDs for various services. Although this disclosure uses PAC networks and PDs as examples to develop and illustrate this disclosure, it should be noted that this disclosure is not limited to these networks. The general concepts developed in this disclosure can be applied in various types of networks and different scenarios.

Communication interface 590 may include one or more communication processors that can operate independently of processor 520 (e.g., application processor (AP)) and support direct (e.g., wired) or wireless communication.

[0103] In one embodiment, such as Figure 5 The electronic device 500 shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term "non-transitory" simply means that the storage medium is a tangible device and does not include signals (e.g., electromagnetic waves), but this term does not distinguish between data that is semi-permanently stored in the storage medium and data that is temporarily stored in the storage medium.

[0111] According to one embodiment of this disclosure, methods according to various embodiments of this disclosure can be included and provided in a computer program product. The computer program product can be traded as a product between a seller and a buyer.

According to various embodiments, operations performed by a module, program, or other component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more operations may be performed in a different order or omitted, or one or more other operations may be added.

[0113] Ultra-wideband (UWB) based pulse radio technology uses short radio pulses for wireless communication. This technology offers numerous advantages, such as low-complexity transceiver design, high capacity through the utilization of large bandwidth, and robustness against inter-symbol interference (ISI) in multipath environments. Furthermore, the short radio pulse characteristic significantly reduces the probability of unintentional interception and eavesdropping by unauthorized parties. This enables secure communication for data transmission and ranging. The IEEE 802.15.4z standard is currently under development to improve the accuracy, integrity, and efficiency of UWB-based pulse radio communication.

[0114] Ranging and relative positioning are essential for various location-based services and applications, such as Wi-Fi direct communication and the Internet of Things (IoT). The number of networked devices in the wireless ecosystem is experiencing tremendous growth, significantly increasing the demand for ranging requests and the number of related ranging messages exchanged over the network. Currently, in the IEEE standard, dedicated resource elements are allocated to ranging pairs in a contention-free period (CFP) to enable unicast ranging in sequence (i.e., one-to-one). Furthermore, using broadcast transmission can reduce the number of ranging exchanges required. For example, a device can initiate ranging with multiple responders by broadcasting ranging frames.

Figure 16This disclosure is not intended to limit the scope to any particular implementation.

[0146] In one embodiment, example ranging mode values ​​for ranging auxiliary data 1600 (in the payload) can be derived from, for example... Figure 8 For use by the controller and / or controlled party as shown. Figure 8 The controllers and / or controllers shown may, for example, Figure 5 Implemented in the illustrated electronic device, the electronic device can be implemented as follows Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0147] Figure 17 An exemplary ranging mode value 1700 for ranging auxiliary data (in a payload) with and without RFRAME is shown according to an embodiment of the present disclosure. Figure 17 The example of ranging mode value 1700 shown is for illustrative purposes only. Figure 17 This disclosure is not intended to limit the scope to any particular implementation.

[0148] In one embodiment, the ranging mode value 1700 can be derived from, for example: Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0149] In one embodiment, a scheme is provided for transmitting ranging auxiliary data using an Advanced Ranging Control IE. New modes are defined in the ranging mode values ​​of the Advanced Ranging Control IE, with several examples as follows: Figure 16 and Figure 17 As shown.

[0150] Figure 18 A flowchart of a method 1800 for indicating ranging auxiliary data (in a payload) using ranging mode values, according to an embodiment of the present disclosure, is shown. Figure 18 The embodiments of method 1800 shown are for illustrative purposes only. Figure 18 This disclosure is not intended to limit the scope to any particular implementation.

[0151] In one embodiment, method 1800 may be performed by, for example Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1The UE and / or base station shown (e.g., 111-116 and 101-103).

[0152] like Figure 18 As shown, method 1800 begins at step 1802. In step 1802, a ranging control message is received. In step 1804, the method determines whether the ranging mode value indicates ranging assistance data. If the method determines that the ranging mode value indicates ranging assistance data, the method proceeds to step 1806. In step 1806, ranging assistance data is expected. In step 1805, if the method determines that the ranging mode value does not indicate ranging assistance data, the method proceeds to step 1808. In step 1808, no ranging assistance data is found.

[0153] Note that other values ​​for the ranging mode used to represent ranging assistance data (in the payload) are not excluded. When reading the ranging mode value, the receiver equipment can identify which ranging cycle can be used for ranging assistance data (in the payload). This is in Figure 18 It is described as a flowchart.

[0154] This enables data communication within a ranging loop without interrupting the current session. It also allows the use of inactive ranging loops within a block to transmit potentially needed information, messages, or data without interrupting the current ranging session or initiating a new session for data transmission. This is used in conjunction with the ranging scheduling IE to schedule (in the payload) ranging auxiliary data polling (or data) and acknowledgment as needed. It can also be used in conjunction with the contention cycle IE. For the purpose of ranging auxiliary data (in the payload), the initiator sends data / messages, and the responder receives data / messages.

[0155] In one embodiment, a scheme is provided for transmitting ranging auxiliary data (in the payload) using ranging auxiliary data IE.

[0156] Figure 19 An example of ranging auxiliary data IE 1900 (in a payload) according to an embodiment of this disclosure is shown. Figure 19 The example of the ranging auxiliary data IE 1900 (in the payload) shown is for illustrative purposes only. Figure 19 This disclosure is not intended to limit the scope to any particular implementation.

[0157] In one embodiment, the ranging auxiliary data IE 1900 (in the payload) can be obtained from, for example... Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1The UE and / or base station shown (e.g., 111-116 and 101-103).

[0158] The ranging cycle can be used with ranging auxiliary data (IE) (in the payload) and ranging auxiliary data (IE) (in the payload). This IE can be used as follows: Figure 19 The format shown is correct.

[0159] The scheduling mode field specifies whether the ranging used in subsequent ranging loops is contention-based or scheduling-based. When scheduling mode = 0, contention-based ranging is used in subsequent loops. When scheduling mode = 1, scheduling-based ranging is used in subsequent loops. When scheduling mode = 0, the ranging initiator / responder list IE and the ranging contention cycle IE can be invoked. When scheduling mode = 1, the ranging scheduling IE can be invoked.

[0160] The timing parameter indicates whether columns 3-7 exist. If the timing parameter = 1, then columns 3-7 exist. Otherwise, the ranging auxiliary data transmission (in the payload) follows the time structure that has been transmitted in place via a higher-level or advanced ranging control IE or other methods.

[0161] The time structure indicator field specifies whether the ranging used in the subsequent ranging loop is in interval-based mode (0) that calls the ranging interval update IE, or in block-based mode (1) that calls the ranging loop start IE, the next ranging loop IE, and the ranging block update IE.

[0162] The block length multiplier field specifies the multiplier of the minimum block length to calculate the distance measurement block length.

[0163] The number of active ranging cycles specifies the number of active ranging cycles managed by ARC IE. The minimum block length field specifies the minimum length (duration) of a ranging block. The length of a ranging slot specifies the length (duration) of each ranging slot.

[0164] In one embodiment, a scheme is provided for using reserved bits to transmit ranging auxiliary data in an advanced ranging control (IE).

[0165] A single field in existing information elements in 802.15.4z or any similar standard, such as the Advanced Ranging Control IE (excluding other IEs), can be used as an indicator to configure the ranging loop for ranging-assisted data transmission.

[0166] Figure 20 An example of ranging auxiliary data IE (in the payload) having message mode 2000 is shown according to an embodiment of the present disclosure. Figure 20 The embodiment of the IE2000 ranging assistance data (in the payload) with message mode shown is for illustrative purposes only. Figure 20 This disclosure is not intended to limit the scope to any particular implementation.

[0167] In one embodiment, the ranging assistance data IE2000 with a message pattern (in the payload) can be generated by, for example... Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

Figure 21 The example of the ranging auxiliary data bits (in the payload) in the ARC IE 2100 shown is for illustrative purposes only. Figure 21 This disclosure is not intended to limit the scope to any particular implementation.

Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0170] Reserved bits from the Advanced Ranging Control (IE) can be used as indicators to suggest that the current ranging cycle can be used for ranging-aided data transmission. Figure 21 The diagram illustrates the fields of the ARC IE that support this for both formats, but does not exclude other ARC IE formats or any other IE. For a ranging loop to be configured for transmitting ranging auxiliary data, the ranging auxiliary data bit (in the payload) is set to 1; otherwise, the bit is set to 0.

[0171] Figure 22 A flowchart is shown of a method 2200 for indicating ranging-aided data transmission using ranging-aided data bits (in the payload) in the ARC IE, according to an embodiment of the present disclosure. Figure 22 The embodiments of method 2200 shown are for illustrative purposes only. Figure 22 This disclosure is not intended to limit the scope to any particular implementation.

[0172] In one embodiment, method 2200 can be performed by, for example Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0173] For a ranging loop to be configured for transmitting ranging auxiliary data, the ranging auxiliary data bit (in the payload) is set to 1; otherwise, the bit is set to 0. The flowchart is in... Figure 22 As shown in the image.

[0174] like Figure 22 As shown, method 2200 begins at step 2202. In step 2202, a ranging control message is received. In step 2204, the method determines whether the "(in the payload) ranging auxiliary data" bit is equal to 1. In step 2204, if the method determines that the "(in the payload) ranging auxiliary data" bit is equal to 1, then the method proceeds to step 2206. In step 2206, a ranging loop for transmitting ranging auxiliary data is configured. In step 2204, if the method determines that the "(in the payload) ranging auxiliary data" bit is not set to 1, then the method proceeds to step 2208. In step 2208, there is no ranging auxiliary data.

[0175] In one embodiment, a scheme uses the ranging method field in the Advanced Ranging Control IE to transmit ranging auxiliary data.

[0176] Figure 23 An exemplary ranging method field value 2300 for indicating ranging-aided information exchange (or data transmission) according to an embodiment of the present disclosure is shown. Figure 23 The example of the ranging method field value 2300 shown is for illustrative purposes only. Figure 23 This disclosure is not intended to limit the scope to any particular implementation.

[0177] In one embodiment, the ranging method field value 2300 can be derived from, for example: Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0178] Figure 24A flowchart is shown of a method 2400 for indicating distance-aided information exchange or data transmission using a distance measurement method field in ARC IE, according to an embodiment of the present disclosure. Figure 24 The embodiments of method 2400 shown are for illustrative purposes only. Figure 24 This disclosure is not intended to limit the scope to any particular implementation.

[0179] In one embodiment, method 2400 can be derived from, for example... Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0180] like Figure 24 As shown, method 2400 begins at step 2402. In step 2402, a ranging control message is received. In step 2404, the method determines whether the value of the "ranging method" field is set to 11. In step 2404, if the method determines that the value of the "ranging method" field is set to 11, then the method executes step 2406. In step 2406, a ranging loop for exchanging / transmitting ranging assistance information is configured. In step 2404, if the method determines that the value of the "ranging method" field is not set to 11, then the method executes step 2408. In step 2408, ranging assistance information / data is not received.

[0181] The distance measurement method field in ARC IE can be used to convey that the loop is being used for distance measurement assistance information exchange or distance measurement assistance data. Figure 23 The diagram illustrates the ranging method field 11, used to indicate the exchange (or data transmission) of ranging auxiliary information. Figure 24 An illustrative flowchart is shown below.

[0182] In one embodiment, a ranging auxiliary data / message counter and type (e.g., ranging auxiliary data / message counter and type (RADCT)IE) are provided.

[0183] Based on the message length, a given message can be "polled" multiple times. To indicate how many frames (or polls) remain after the current poll to complete the message, the Range Auxiliary Data / Message Counter and Type (RADCT)IE is included in the "Polling (Data)" field to indicate the number of frames remaining to complete the current message. Additionally, the message type can be transmitted using the "Message Type" field. The RADCT IE can be formatted as follows: Figure 25 As shown.

[0184] Figure 25 An exemplary (in payload) ranging auxiliary data counter and type IE format 2500 are shown according to an embodiment of this disclosure. Figure 25 The example shown (in the payload) ranging auxiliary data counter and type IE format 2500 is for illustrative purposes only. Figure 25 This disclosure is not intended to limit the scope to any particular implementation.

[0185] In one embodiment, the ranging auxiliary data counter (in the payload) and the Type IE format 2500 can be provided by, for example... Figure 8 Used by the controller and / or controlled as shown. Can be used as... Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103). Other methods of transmitting messages include, but are not limited to, adding additional fields in the Advanced Ranging Control IE, the Ranging Auxiliary Data IE, and / or defining a dedicated IE for this purpose.

Figure 26 The example shown, which illustrates the distance measurement assistance information message counter and the IE content field format 2600, is for illustrative purposes only. Figure 26 This disclosure is not intended to limit the scope to any particular implementation.

[0187] In one embodiment, the ranging assistance information message counter and the type IE content field format 2600 can be determined by, for example...

Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The UE and / or base station shown (e.g., 111-116 and 101-103).

[0188] In one embodiment, a ranging assist information message counter and a type IE are provided. The ranging assist information message counter and type IE (RAICT IE) are used during ranging assist information exchange (in the payload). The IE can be formatted, such as... Figure 26 As shown.

[0189] The initiator uses this IE in two ways: to transmit to the responder the sequence number of the current data frame, the number of remaining ranging auxiliary data frames to complete the message, and the message type; and to request the controller to schedule the number of time slots specified in the number of remaining data frames (or polls).

[0190] The "To Controller" bit (with RCR) is set to 1 to request a time slot from the controller using the RADCT IE. Otherwise, it is set to 0. The "Sequence Number Present" bit is set to 1 if a sequence number exists, otherwise it is set to 0. The "Message Type Present" bit is set to 1 if a message type is being transmitted. The sequence number is the eight-bit byte that transmits the sequence number of the MAC frame. The number of remaining data frames (or polling) is the number of remaining ranging-aided data frames transmitted to the responder to complete the current message / data. In this disclosure, the RADCT IE can be used as the RAICT IE. In this disclosure, the RADCT IE and RAICT IE can be interchangeable and interchangeable. In this disclosure, the RADCT IE and RAICT IE can have the same usage and content.

Figure 1 The 101-103 shown and as Figure 5 (as shown in 500) to execute. Figure 27 The embodiment of the electronic device 500 shown is for illustrative purposes only.

Figure 5 The electronic device shown implements, as Figure 8 The controller and / or controlled entity shown can be implemented as follows: Figure 1 The network entities and / or base stations shown (e.g., 101-103).

[0193] like Figure 27 As shown, method 2700 begins at step 2702. In step 2702, the network entity identifies one or more ranging loops in the ranging block for transmitting ranging control messages (RCM) and ranging auxiliary data.

[0194] Subsequently, in step 2704, the network entity generates an RCM that includes an Advanced Ranging Control Information Element (ARC IE), which includes a ranging method field, wherein the ranging method field includes a value indicating whether a ranging loop following the RCM is used for ranging auxiliary information exchange.

[0196] Next, in step 2706, when the value included in the ranging method field corresponds to ranging auxiliary information exchange, the first network entity sends ranging auxiliary data to the second network entity in the ranging loop after RCM.

[0197] Finally, in step 2708, the first network entity receives an acknowledgment (ACK) corresponding to the ranging assistance data from the second network entity.

[0198] In one embodiment, when the value included in the ranging method field corresponds to ranging assistance information exchange, the first network entity sends ranging assistance data to a group of network entities, including the second network entity, in the ranging loop following RCM.

[0199] In one embodiment, the first network entity receives an ACK corresponding to ranging auxiliary data from a group of network entities, including the second network entity.

[0200] In one embodiment, during the exchange of ranging assistance information, a first network entity generates a ranging assistance information message counter and a type IE (RAICT IE), wherein the RAICT IE includes: a ranging or assistance message number presence field indicating whether a sequence number field exists in the RAICT IE; a reserved field; a ranging or assistance message number field indicating a Media Access Control (MAC) frame sequence number; and a remaining frame field indicating the number of remaining frames to complete the ranging assistance data.

[0201] In one embodiment, a first network entity sends a RAICT IE to a second network entity to indicate the ranging or auxiliary message number of the data frame being transmitted and the number of remaining ranging auxiliary data frames, which are messages or message types, to complete the data frame.

[0202] In such embodiments, the first network entity is the initiator, which initiates ranging exchange or sends ranging assistance information to the second network entity by first sending a message to the second network entity; the second network entity is the responder that receives ranging assistance information from the first network entity and responds to the message first received from the first network entity.

[0203] In one embodiment, a first network entity receives a RAICT IE including a request field. In such an embodiment, the request field indicates that the RAICT IE requests the first network entity to schedule multiple time slots; the first network entity is a controller that sends a ranging cycle to a second network entity for data transmission purposes based on the number of time slots scheduled; the second network entity is a controller that requests the first network entity to schedule the multiple time slots.
