Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a method, apparatus and communication equipment for determining signal transmission parameters. Background Technology

[0002] Some Internet of Things (IoT) devices, such as tags, require carrier excitation signals for power. The tag encodes the carrier excitation signal and sends it to the reader.

In related technologies, a certain time interval is required between the signal transmission between the reader and the tag.

[0049] Before describing the embodiments of this application, the relevant technologies are briefly introduced below:

[0050] I. Types of Ambient IoT (AIoT) Devices

[0051] In the 3rd Generation Partnership Project (3GPP) R19 A-IoT study, A-IoT devices are characterized by their energy storage capacity and ability to generate and transmit radio frequency signals. A-IoT devices include the following types:

[0052] Type A: It has energy storage but no independent signal generation / amplification, i.e., backscatter transmission.

[0053] Type B: It has energy storage but no independent signal generation, i.e., backscatter transmission. The use of stored energy can include amplification of the reflected signal.

[0054] Type C: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.

[0055] A-IoT devices can be, for example, tags. Continuous-Wave (CW) nodes power tags by sending carrier excitation signals (CW signals), which the tags then encode and send to the reader. Tags with different energy storage capacities exhibit varying transmission quality. Devices with higher energy storage typically have higher receiver sensitivity or higher transmit power, resulting in better reliability of the receive or transmit link.

[0056] II. AIoT Business Types

[0057] The main data / service types of A-IoT include Device-originating (DO) data and Device-terminated (DT) data. DO data indicates that the data stream originates from an A-IoT device (similar to a Radio Frequency Identification (RFID) tag), while DT data indicates that the data stream is transmitted to an A-IoT device. DO data can be further divided into the following types:

[0058] Autonomous DO (DO-A): This refers to AIoT devices autonomously initiating data transmission. For example, AIoT devices connect to a large number of various sensors, which collect information and proactively report information about the environment, devices, and organisms when necessary.

[0059] Device-terminated triggered (DO-DTT) refers to a data transmission initiated by an AIoT device via a reader device, such as a base station. For example, in asset identification, status reporting, and tracking, the Reader collects data from a Tag by triggering an inventory procedure. Since the data is generated / initiated within the IoT device, this service should be considered as a DO service initiated by the Tag via a control command on the Reader side.

[0060] III. AIoT Topology Types

[0061] Topology 1:

[0062] For Topology-1, 3GPP has reached an agreement to further investigate the following cases:

[0063] Case 1-1: CW is transmitted by BS on the DL spectrum, i.e., BS acts as CW node, such as... Figure 2 As shown;

[0064] Case 1-2: CW is transmitted by the BS on the UL spectrum, i.e., the BS acts as the CW node, such as... Figure 2 As shown;

[0065] Cases 1-4: CW is transmitted on the UL spectrum by a CW node outside the Topology, such as... Figure 3 As shown.

[0066] Topology 2:

[0067] For Topology-2, 3GPP has reached an agreement to further study the following cases:

[0068] Case 2-2: CW is transmitted by the Intermediate UE on the UL spectrum, i.e., the Intermediate UE acts as the CW node, such as... Figure 4 As shown;

[0069] Cases 2-3: CW is transmitted on the DL spectrum by a CW node outside the Topology, such as... Figure 5 As shown;

[0070] Cases 2-4: CW is transmitted on the UL spectrum by a CW node outside the Topology, such as... Figure 5 As shown.

[0071] When CW is transmitted from a CW node outside the Topology, the CW may not be transmitted continuously, but rather in a certain transmission time pattern. The CW signal can be transmitted periodically, for example, as... Figure 6 As shown, the period T and transmission time T1 of the CW signal are configured. By default, the CW signal is transmitted during the first T1 time period of each period T, and no CW signal is transmitted during the subsequent (T-T1) time period.

[0072] CW signals can also be sent periodically according to a certain pattern. Within the pattern, the transmission of CW signals is aperiodic, such as... Figure 7 As shown, the period of the pattern is 110ms. Within the pattern, a 30ms CW signal is sent first, then the transmission stops for 20ms, then a 40ms CW signal is sent, and then the transmission stops for another 20ms. The CW signal is sent periodically using the pattern described above.

[0073] IV. Reader-to-Device (R2D) transmission in RFID (i.e., Reader-to-Tag transmission)

[0074] In RFID, before sending data or commands to a tag, the reader first sends a preamble or frame-sync. The format of the preamble is as follows: Figure 8 As shown, the format of frame-sync is as follows: Figure 9 As shown. A Preamble contains a fixed-length delimiter, a data-0 symbol, an R (Reader) to T (Tag) calibration (RTcal) symbol, and a T to R calibration (TRcal) symbol. A Frame-sync does not contain a TRcal symbol, but its structure is the same as the Preamble. The Reader sends the Preamble or Frame-sync to the Tag before sending data or commands (e.g., sending a Query command after sending the Preamble). The Delimiter and other OFF chips in the Preamble / Frame-sync, as well as the OFF chip in the R2D command, can be considered as a null value. Currently, the transmission of the CW signal is controlled by the Reader; specifically, the CW signal can be sent by the Reader. Since the delimiter / OFF chip are both null values ​​(which can be understood as zero-level signals), the Reader needs to stop sending the CW signal during the delimiter / OFF chip period; otherwise, the delimiter / OFF chip cannot be constructed.

[0075] In addition, 3GPP is currently conducting research and discussion on midamble and postamble. Midamble is added between the information bits of R2D (or D2R) for clock synchronization and channel estimation, while postamble is added after the information bits of R2D (or D2R) for channel estimation, time synchronization, and indicating the end position of transmission.

[0076] V. Timing Relationship between R2D and D2R Transmissions in AIoT

[0077] Currently, 3GPP has reached an agreement to study the time relationship between R2D transmission and Device-to-Reader (D2R) transmission (i.e., Tag-to-Reader transmission) in AIoT. Among these, T... R2D_min T refers to the minimum time between one R2D transmission and the subsequent corresponding D2R transmission.D2R_min T refers to the minimum time interval between a D2R transmission and the subsequent corresponding R2D transmission. R2D_R2D_min T refers to the minimum time interval between two consecutive R2D transmissions with the same AIoT device. D2R_D2R_min This refers to the minimum time interval between two consecutive D2R transmissions from the same AIoT device. Furthermore, in AIoT, T... R2D T D2R There may also be a maximum value requirement, such as T. R2D_max T D2R_max .

[0078] As shown above, in the R19-AIoT research, CW can be sent by devices within the Topology or by devices outside the Topology. When CW is sent by a CW node outside the Topology, CW may not be sent continuously, but rather in a certain transmission time pattern. Furthermore, the CW transmission time pattern may only be visible to the UE or network-side devices, but not to the Tag; that is, the Tag is unaware of the CW transmission time pattern. In addition, Tags can only be transmitted via backscatter, therefore D2R signals can only be transmitted within the CW signal transmission time resources, while R2D signals can only be transmitted within the CW non-transmission time resources. Moreover, to satisfy the timing relationship between R2D and D2R, the time interval T between R2D transmission and the subsequent corresponding D2R transmission... R2D Requirement not less than T R2D_min and / or not greater than T R2D_max The time interval T between the end of a D2R transmission and the start of a subsequent corresponding R2D transmission. D2R Requirement not less than T D2R_min and / or not greater than T D2R_max .

[0079] In this case, the transmission time pattern of CW may conflict with the timing relationship of R2D / D2R. For example, in Figure 10 In this context, since R2D transmission only occurs during the non-transmission time resources of CW, if D2R transmission ends early, it may cause T... D2R Greater than T D2R_max Similarly, since D2R transmission can only occur within the CW transmission time, if R2D transmission ends early, it may cause T... R2D Greater than T R2D_max Therefore, in the case of discontinuous CW transmission, in order to satisfy the timing relationship between R2D and D2R, it is necessary to ensure that the start time of CW transmission is T after the end of R2D signal transmission. R2D_min Within the time frame, ensure that the end time of CW transmission is within T after the end of D2R transmission. D2R_maxWithin the time frame.

[0080] In view of this, embodiments of this application provide a method, apparatus, and communication device for determining signal transmission parameters to solve the related problems in the art caused by the transmission of CW signals not being controlled by the Reader.

[0081] The signal transmission parameter determination method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0082] Figure 11 This diagram illustrates a flowchart of a signal transmission parameter determination method provided in an embodiment of this application. Figure 11 As shown, the method for determining signal transmission parameters includes the following steps:

[0083] Step 1101: The first device acquires the transmission time parameters corresponding to the first signal, wherein the first signal includes a carrier excitation signal;

[0084] Step 1102: The first device determines the transmission time parameter of the first sub-signal in the second signal based on at least one of the transmission time parameter corresponding to the first signal and the first time length.

[0085] The first device can be understood as a handheld or fixed device that reads (and sometimes writes) tag information (i.e., a Reader), or a device that communicates with the second device (such as a tag). The first device can be, for example, a terminal or a base station. Alternatively, the first device can be understood as a device with read and write functions, such as a reader.

[0086] The second device can be understood as a response device. In one possible implementation, it can be a tag, specifically an electronic tag (i.e., an RFID tag). RFID can be further divided into active, passive, and semi-active types. Passive tags can also be called passive IoT, i.e., passive Internet of Things devices. The communication method of the second device can be signal transmission via backscattered radio frequency (RF) signals, or some active tags can have the ability to actively generate signals. Because the energy of the second device can come from the environment, such as ambient RF energy, heat energy, wind energy, or kinetic energy, the second device can also be called an AIoT device. The second device can be regarded as a terminal and can be called a terminal device.

[0087] In this embodiment, the first device can communicate with the second device by sending a second signal. That is, the transmission direction of the second signal is from the first device to the second device. Therefore, the second signal can be understood as an R2D signal, or as including a Preamble, clock acquisition within a Preamble, or an R2D signal. Besides sending the second signal, the first device can also send a first signal. The first signal can also be sent by a third device other than the first device. The first signal can be understood as a CW signal, and the third device can be understood as a CW node. Correspondingly, the second device can respond by backscattering the first signal to generate a third signal. The transmission direction of the third signal is from the second device to the first device; therefore, the third signal can be understood as a D2R signal.

[0088] In related technologies, the transmission of the first signal is controlled by a first device; that is, the first device controls whether the first signal is transmitted or not. In this embodiment, the transmission of the first signal may not be controlled by the first device, but rather by a device transmitting the first signal based on a predefined or configured transmission time parameter. Since the transmission of the first signal is not controlled by the first device, the first device does not know how the first signal is transmitted, and therefore cannot determine how the second signal is transmitted, making the transmission of the second signal impossible. Therefore, by obtaining the transmission time parameter corresponding to the first signal, the first device can know how the first signal is transmitted. Thus, the first device can determine the transmission time parameter of the first sub-signal in the second signal based on at least one of the transmission time parameter and the first time length, and construct the first sub-signal according to the transmission time parameter of the first sub-signal in the second signal.

[0089] In this embodiment of the application, at least some of the transmission parameters corresponding to the first signal can be predefined by the protocol, configured by the network-side device, or configured by the first device.

[0090] In this embodiment, the first sub-signal can be understood as a signal portion added to the second signal to adjust the length of the transmission time resource of the second signal so that the length of the transmission time resource of the second signal can satisfy the timing relationship of R2D and D2R transmission. The first sub-signal can be empty information or null value, or it can be data information, or it can be a combination of empty information and data information. The data information in the first sub-signal can be valid data information (such as information bits or clock synchronization signals, etc.) or it can be data information used only for filling. This embodiment does not limit this.

[0091] Since the first sub-signal is part of the second signal, determining the transmission time parameter of the first sub-signal in the second signal can also be understood as determining the transmission time parameter of the second signal.

[0092] In this embodiment, the first time length can be understood as the time length related to the timing relationship between R2D transmission and D2R transmission, or in other words, the first time length is determined based on the timing relationship between R2D transmission and D2R transmission. In this way, the first sub-signal constructed by the first device can satisfy the timing relationship between R2D transmission and D2R transmission, thereby ensuring the transmission performance of R2D transmission and D2R transmission.

[0093] In this embodiment, a first device acquires a transmission time parameter corresponding to a first signal, the first signal including a carrier excitation signal. The first device determines the transmission time parameter of a first sub-signal in a second signal based on at least one of the transmission time parameter corresponding to the first signal and a first time length. Thus, by acquiring the transmission time parameter corresponding to the first signal, the first device can determine the transmission time parameter corresponding to the second signal based on at least one of the transmission time parameter corresponding to the first signal and the first time length, thereby enabling the transmission of the second signal and ensuring transmission performance between the first device and the IoT device.

[0094] In this embodiment, there can be multiple sub-signal types, and different sub-signal types can correspond to different transmission time parameters. Therefore, the first device can indirectly determine the transmission time parameters of the first sub-signal by determining the type of the first sub-signal. The sub-signal types and the corresponding transmission time parameters for different sub-signal types can be predefined by network configuration or protocol, or determined by the first device itself. Alternatively, there can be multiple transmission time parameters for the first sub-signal, and the different transmission time parameters of the first sub-signal can be predefined by network configuration or protocol, or determined by the first device itself. For example, the network configures multiple sub-signal types and corresponding transmission time parameters for each sub-signal type. The first device determines the type of the first sub-signal from these multiple sub-signal types based on at least one of the transmission time parameters corresponding to the first signal and the first time length, thereby determining the transmission time parameters of the first sub-signal. As another example, the network configures multiple transmission time parameters, and the first device determines the transmission time parameters of the first sub-signal from these multiple transmission time parameters based on at least one of the transmission time parameters corresponding to the first signal and the first time length. The method of protocol predefinition can refer to the method of network configuration; to avoid repetition, it will not be elaborated further.

[0095] In some embodiments, the first time length is determined based on at least one of the following:

[0096] The minimum time interval between the second signal and the third signal;

[0097] The maximum time interval between the second signal and the third signal;

[0098] The minimum time interval between the second signal and the fourth signal;

[0099] The maximum time interval between the second signal and the fourth signal;

[0100] Wherein, the second signal is a signal sent by the first device, the third signal is a signal sent by the second device, and the fourth signal is a signal sent by the first device, wherein the second device includes an Internet of Things (IoT) device.

[0101] In one implementation, the third signal is a signal sent by the second device after receiving the second signal, and the fourth signal is a signal sent by the first device after receiving the third signal. The second device can be found in the foregoing description of the second device; to avoid repetition, it will not be described again.

[0102] In one implementation, the second signal is an R2D signal, the third signal is a D2R signal, and the fourth signal is an R2D signal.

[0103] The minimum time interval between the second and third signals can be understood as the aforementioned T. R2D_min .

[0104] The maximum time interval between the second and third signals can be understood as the aforementioned T. R2D_max .

[0105] The minimum time interval between the second and fourth signals can be understood as the aforementioned T. R2D_R2D_min .

[0106] The maximum time interval between the second and fourth signals can be understood as the aforementioned T. R2D_R2D_max .

[0107] In other words, the first time length is determined based on the timing relationship between R2D and D2R transmissions. In this way, the transmission time parameters of the first sub-signal determined by the first device can meet the timing relationship between R2D and D2R transmissions, thereby ensuring the transmission performance of R2D and D2R transmissions.

[0108] In some embodiments, the transmission time parameter of the first sub-signal includes at least one of the following:

[0109] The transmission time length of the first sub-signal;

[0110] The transmission start time of the first sub-signal;

[0111] The transmission end time of the first sub-signal.

[0112] In some embodiments, the first sub-signal satisfies at least one of the following conditions:

[0113] The first sub-signal is located at the beginning of the second signal;

[0114] The first sub-signal is located at the tail of the second signal.

[0115] The first device may add the first sub-signal only at the beginning of the second signal, or only at the end of the second signal, or add the first sub-signal at both the beginning and the end of the second signal.

[0116] In some embodiments, the first sub-signal includes at least one of the following:

[0117] A continuous zero-level signal; a continuous high-level signal; a carrier signal with one or more single-frequency points.

[0118] A zero-level signal, also known as a low-level signal, is equivalent to a null value.

[0119] Optionally, one or more single-frequency carrier signals include at least one of the following:

[0120] One or more single-frequency sinusoidal signals;

[0121] One or more single-frequency cosine signals.

[0122] Whether the first sub-signal is located at the beginning or end of the second signal, and whether it is a continuous zero-level signal, a continuous high-level signal, or one or more single-frequency carrier signals, can be flexibly selected based on the type of the first sub-signal. Embodiments of this application provide first sub-signals of at least one of the following types for reference: start indicator, delimeter, preamble, clock acquisition signal, midamble, postamble, information bits, predefined signal, and sequence pattern of a specific format.

[0123] For example, first sub-signals of types such as end codes, predefined signals, and sequences of specific formats can be placed at the end of the second signal, while first sub-signals of types such as start symbols, separators, preambles, clock synchronization signals, predefined signals, and sequences of specific formats can be placed at the beginning of the second signal. For example, if a first sub-signal of type such as a predefined signal or a sequence of specific formats is sent before the separator or placed at the end of the second signal, the signal can be a continuous high-level signal or one or more single-frequency carrier signals; a first sub-signal of type such as a start symbol or separator can be a continuous low-level signal or a zero-level signal.

[0124] In some embodiments, the encoding method of the first sub-signal is different from the encoding method of the signals in the second signal other than the first sub-signal. This enables the second device to distinguish between the first sub-signal and the signals other than the first sub-signal, thereby enabling it to better understand the second signal.

[0125] In some embodiments, the transmission time indicated by the transmission time parameter corresponding to the first signal is located after the transmission time of the second signal.

[0126] The transmission time parameters of the first sub-signal determined by the first device are based on the transmission time parameters of the first signal that follow the second signal. In other words, the first signal is the next first signal after the second signal. Within the transmission time resources of this next first signal, the second device needs to perform D2R transmission. Therefore, the transmission time parameters of the first sub-signal determined by the first device can satisfy T... R2D The relevant requirements are met to ensure the transmission performance of R2D and D2R transmissions.

[0127] In some embodiments, the first device determines the transmission time parameter of the first sub-signal in the second signal based on the transmission time parameter corresponding to the first signal and the first time length, including:

[0128] When the transmission mode of the first signal is discontinuous transmission, the first device determines the transmission time parameter of the first sub-signal in the second signal based on the transmission time parameter corresponding to the first signal and the first time length.

[0129] In other words, the embodiments of this application can be used when the first signal is transmitted discontinuously.

[0130] In one implementation, the first signal discontinuous transmission includes at least one of the following:

[0131] Case 1: The first signal is sent periodically;

[0132] Case 2: The first signal is sent periodically, and within the period, the first signal includes N sub-signals. The N sub-signals are sent non-periodically. The duration of each sub-signal and / or the time interval between the sub-signals are determined by configuration or predefinition, where N is an integer greater than 1.

[0133] Case 3: The first signal includes M sub-signals, which are sent aperiodically. The duration of each sub-signal and / or the time interval between sub-signals are determined by configuration or predefinition, where M is an integer greater than 1.

[0134] The period in the above situation can be determined by configuration or by predefinition.

[0135] The above are method embodiments on the first device side. The following describes method embodiments on the second device side.

[0136] Figure 12 This diagram illustrates a flowchart of a signal transmission parameter determination method provided in an embodiment of this application. Figure 12 As shown, the method for determining signal transmission parameters includes the following steps:

[0137] Step 1201: The second device acquires first information, which is used to indicate the target time resource;

[0138] Step 1202: The second device determines the transmission time parameter of the second sub-signal in the third signal based on at least one of the target time resource and the second time length.

[0139] In this embodiment of the application, the second device can obtain the target time resource and determine the transmission time parameter corresponding to the third signal based on at least one of the target time resource and the second time length, thereby enabling the transmission of the third signal and ensuring the transmission performance between the first device and the second device.

[0140] Optionally, the second time length is determined based on at least one of the following:

[0141] The minimum time interval between the third signal and the fifth signal;

[0142] The maximum time interval between the third signal and the fifth signal;

[0143] The minimum time interval between the third signal and the sixth signal;

[0144] The maximum time interval between the third signal and the sixth signal;

[0145] The third signal is a signal sent by the second device, the fifth signal is a signal sent by the first device, and the sixth signal is a signal sent by the second device.

[0146] In one implementation, the fifth signal is a signal sent by the first device after receiving the third signal, and the sixth signal is a signal sent by the second device after receiving the fifth signal.

[0147] In one implementation, the third signal is a D2R signal, the fifth signal is an R2D signal, and the sixth signal is a D2R signal.

[0148] The minimum time interval between the third and fifth signals can be understood as the aforementioned T. D2R_min .

[0149] The maximum time interval between the third and fifth signals can be understood as the aforementioned T. D2R_max .

[0150] The minimum time interval between the third and sixth signals can be understood as the aforementioned T. D2R_D2R_min .

[0151] The maximum time interval between the third and sixth signals can be understood as the aforementioned T. D2R_D2R_max .

[0152] In other words, the second time length is determined based on the timing relationship between R2D and D2R transmissions. In this way, the transmission time parameters of the second sub-signal determined by the second device can meet the timing relationship between R2D and D2R transmissions, thereby ensuring the transmission performance of R2D and D2R transmissions.

[0153] Optionally, the transmission time parameter of the second sub-signal includes at least one of the following:

[0154] The transmission time length of the second sub-signal;

[0155] The transmission start time of the second sub-signal;

[0156] The transmission end time of the second sub-signal.

[0157] Optionally, the second sub-signal satisfies at least one of the following conditions:

[0158] The second sub-signal is located at the beginning of the third signal;

[0159] The second sub-signal is located at the tail of the third signal.

[0160] The second device may add a second sub-signal only at the beginning of the third signal, or only at the end of the third signal, or add a second sub-signal at both the beginning and end of the third signal.

[0161] Optionally, the second sub-signal includes at least one of a preamble, a predefined signal, and a sequence of a specific format.

[0162] For example, the second sub-signal can be the preamble itself or a sub-signal preceding the preamble. In one implementation, the length of the second sub-signal can be adjusted by repeating the preamble, in which case the preamble is variable-length. In another implementation, the preamble length remains constant, and an additional sub-signal is added before the preamble.

[0163] Optionally, the encoding method of the second sub-signal is different from the encoding method of the signals in the third signal other than the second sub-signal. This enables the first device to distinguish between the second sub-signal and signals other than the second sub-signal, thereby enabling it to better understand the third signal.

[0164] Optionally, the second device acquires the first information, including:

[0165] The second device receives first information from the first device.

[0166] In other words, the target time resource is the time resource indicated by the first device.

[0167] Optionally, the target time resource at least partially overlaps with the transmission time resource of the first signal, which includes a carrier excitation signal. That is, the transmission of the first signal occurs within the target time resource.

[0168] Optionally, the transmission mode of the first signal is discontinuous transmission.

[0169] For relevant descriptions of the embodiments in this application, please refer to... Figure 11 The relevant descriptions of the method embodiments, which can achieve the same technical effects, will not be repeated here to avoid repetition.

[0170] To better understand the embodiments of this application, specific embodiments are provided below for illustrative purposes.

[0171] In the following embodiments, the first device is a Reader (or an Intermediate UE), the second device is a Tag, the first signal is a CW signal, the second signal is an R2D signal, the first sub-signal is a first R2D signal (located at the tail) or a second R2D signal (located at the front), the third signal is a D2R signal, and the second sub-signal is a first D2R signal (located at the tail) or a second D2R signal (located at the front). The R2D signal mentioned below refers to the signal sent by the Reader to the Tag, including but not limited to Preamble, Information bits, Midamble, Postamble, etc. Similarly, the D2R signal transmission mentioned below refers to the signal sent by the Tag to the Reader, including but not limited to Preamble, Information bits, Midamble, Postamble, etc. The transmission time resources of the R2D / D2R signals mentioned below include at least one of the following: the start time, end time, and duration of the R2D / D2R signal.

[0172] Example 1: Determining the time resources of R2D signals

[0173] The Reader determines the time resources (i.e., transmission time resources, hereinafter the same) for the R2D signal based on the transmission / non-transmission time of the CW signal. In the case of discontinuous CW transmission, the Reader ensures the timing relationship between R2D signal transmission and the corresponding D2R signal transmission by determining the R2D signal time resources; that is, it ensures that the start time of CW transmission is within T after the end time of R2D signal transmission. R2D_min Within the time frame.

[0174] In some embodiments, the Reader determines the transmission duration or end time of the first R2D signal based on the transmission time of the CW. The first R2D signal can be a postamble; for example, postambles of different durations are available. When determining the R2D postamble, the Reader selects a postamble that satisfies the timing relationship requirements between the R2D and D2R signals. The first R2D signal can also be a predefined signal, such as a predefined signal of a specific format, transmitted after the information bits of the R2D signal or after the postamble. Optionally, the predefined signal can be a continuous high-level signal. Alternatively, the predefined signal can be a repetition of information bits or a postamble. Furthermore, the first R2D signal can employ an encoding method different from that of the information bits.

[0175] For example, such as Figure 13As shown, the first R2D signal is a high-level signal located at the end of the R2D transmission. The Reader determines the transmission length or end time of the first R2D signal based on the start transmission time of the CW, so that the start transmission time of the CW can be located within [T]. _R2D_end T _R2D_end +T _R2D_min This ensures that the D2R transmission is within the CW transmission time, allowing the Tag to perform backscatter communication.

[0176] In some embodiments, the Reader determines the transmission duration or start time of the second R2D signal based on the transmission time of the CW. The second R2D signal can be a start indicator or a delimiter, in which case it can be located at the beginning of the R2D transmission. Optionally, the second R2D signal can be a low-level signal or a zero-level signal. The second R2D signal can also be a preamble or clock acquisition signal, such as a preamble or clock acquisition signal transmitted after the start indicator. The second R2D signal can also be a predefined signal, such as a predefined signal transmitted before the delimiter. Optionally, the second R2D signal can be a continuous high-level signal, or one or more single-frequency sine / cosine signals. This predefined signal can be a repetition of information bits or a postamble.

[0177] For example, such as Figure 14 As shown, the second R2D signal is a high-level signal at the beginning of the R2D transmission and is transmitted before the delimiter. The Reader determines the start time or transmission length of the second R2D signal based on the transmission time of the CW, so that the start time of the CW transmission can be located within [T]. _R2D_end T _R2D_end +T _R2D_min This ensures that the D2R transmission is within the CW transmission time, thus ensuring that the Tag can perform backscatter communication.

[0178] The above can be used in combination. For example, the Reader can determine the appropriate Preamble, Postamble, Delimiter, predefined signals, etc., so that the start time of CW transmission can be located within [T]. _R2D_end T _R2D_end +T _R2D_min ]between.

[0179] Example 2: Determining the Time Resources of D2R Signals

[0180] The Reader indicates the target time resource for the Tag, which is a time resource where CW transmission is present. The target time resource can also be a time resource where CW transmission is absent. In the case of discontinuous CW transmission, the Tag determines the time resource for the D2R signal based on the target time resource indicated by the Reader. This further ensures the timing relationship between the R2D signal transmission and the corresponding D2R signal transmission, i.e., ensuring that the CW transmission end time is within T after the D2R transmission ends. D2R_max Within the time frame, that is, ensuring that the end transmission time of CW is within [T] _D2R_end T _D2R_end +T D2R_max ]between.

[0181] In some embodiments, the Tag determines the transmission duration or end time of the first D2R signal based on the target time resource indicated by the Reader. The first D2R signal can be a postamble; for example, postambles of different durations are available. When determining the R2D postamble, the selected postamble should satisfy the timing relationship requirements between the D2R and R2D signals. The first D2R signal can also be a predefined signal, such as a predefined signal of a specific format, transmitted after the information bits of the D2R signal or after the postamble. Preferably, the predefined signal can employ a different encoding method than the information bit transmission. Alternatively, the predefined signal can be a repetition of information bits or a postamble.

[0182] For example, such as Figure 15 As shown, the first D2R signal is a predefined signal located at the end of the D2R transmission. The Tag determines the transmission length or end time of the first D2R signal based on the target time resource indicated by the Reader, such that the CW transmission end time is located at T after the end of the D2R transmission. D2R_max Within the time frame, that is, ensuring that the end transmission time of CW is within [T] _D2R_end T _D2R_end +T D2R_max This ensures that R2D transmissions begin within the CW's non-transmission time resources.

[0183] In some embodiments, the Tag determines the transmission duration or start time of the second D2R signal based on the target time resource indicated by the Reader. The second D2R signal can be a preamble or a predefined signal transmitted before the preamble. The predefined signal can be a repetition of the preamble.

[0184] For example, such as Figure 16As shown, the second D2R signal is a preamble at the beginning of the D2R transmission. The tag determines the start time or transmission duration of the second D2R signal based on the target time resources indicated by the Reader, such that the CW transmission end time is located at T after the end of the D2R transmission. D2R_max Within the time frame, that is, ensuring that the end transmission time of CW is within [T] _D2R_end T _D2R_end +T D2R_max ]between.

[0185] The above can be used in combination. For example, by determining appropriate preamble, postamble, and predefined signals, Tag can ensure that the CW transmission ends at time T after the D2R transmission ends. D2R_max Within the time frame, that is, ensuring that the end transmission time of CW is within [T] _D2R_end T _D2R_end +T D2R_max ]between.

[0186] In summary, the embodiments of this application provide a method for determining the transmission time parameters of R2D / D2R signals when CW is transmitted in a certain transmission time mode, so that R2D / D2R transmission can meet the required timing relationship.
