Background Technology

[0004] 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 a reader.

In related technologies, the reader controls the transmission of the carrier excitation signal, allowing it to know when to send relevant signals to the tag. However, the transmission of the carrier excitation signal can be independent of the reader's control, necessitating the development of new signal transmission schemes. Summary of the Invention

[0062] Before describing the embodiments of this application, the relevant technologies are briefly introduced below:

[0063] I. Types of Ambient IoT (AIoT) Devices

[0064] 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:

[0065] Type A: It has energy storage but no independent signal generation / amplification, i.e., backscatter transmission.

[0066] 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.

[0067] Type C: It has energy storage and independent signal generation, i.e., an active radio frequency component for transmission.

[0068] 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.

[0069] II. AIoT Business Types

[0070] 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:

[0071] 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.

[0072] 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.

[0073] III. AIoT Topology Types

[0074] Topology 1: Base Station (BS) Ambient IoT device

[0075] For Topology-1, 3GPP has reached an agreement to further investigate the following cases:

[0076] Case 1-1: CW is transmitted by BS on the DL spectrum, that is, BS acts as CW node, as shown in Figure 2;

[0077] Case 1-2: CW is transmitted by BS on the UL spectrum, that is, BS acts as CW node, as shown in Figure 2;

[0078] Cases 1-4: CW is transmitted on the UL spectrum by a CW node outside the Topology, as shown in Figure 3.

[0079] Topology 2:BS Intermediate node Ambient IoT device

[0080] For Topology-2, 3GPP has reached an agreement to further study the following cases:

[0081] Case 2-2: CW is transmitted by the Intermediate UE on the UL spectrum, that is, the Intermediate UE acts as the CW node, as shown in Figure 4;

[0082] Case 2-3: CW is transmitted by a CW node outside the Topology on the DL spectrum, as shown in Figure 5;

[0083] Case 2-4: CW is transmitted on the UL spectrum by a CW node outside the Topology, as shown in Figure 5.

[0084] IV. Reader-to-Device (R2D) transmission in RFID (i.e., Reader-to-Tag transmission)

[0085] 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 shown in Figure 6, and the format of the frame-sync is shown in Figure 7. The 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. The frame-sync does not contain the TRcal symbol, but its other components are the same as the preamble. The reader sends the data or command after sending the preamble or frame-sync to the tag (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.

[0086] Currently, the transmission of the CW signal is controlled by the Reader; specifically, the CW signal can be transmitted by the Reader. Since the delimiter / OFF chip is null (which can be understood as a zero-level signal), the Reader needs to stop transmitting the CW signal during the delimiter / OFF chip period; otherwise, the delimiter / OFF chip cannot be constructed.

[0087] V. Timing Relationship between R2D and D2R Transmissions in AIoT

[0088] 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 interval between an R2D transmission and the corresponding D2R transmission following it. D2R_minT refers to the minimum time interval between a D2R transmission and the corresponding R2D transmission following it. R2D_R2D_min T refers to the minimum time interval between two consecutive R2D transmissions to the same A-IoT device. D2R_D2R_min It refers to the minimum time interval between two different consecutive D2R transmissions from the same A-IoT device.

[0089] As shown above, in current R19-AIoT research, CW signals can be sent by devices within the Topology or by devices outside the Topology. When the CW signal is sent by a CW node outside the Topology, and the Reader within the Topology cannot control the CW node (i.e., the Reader cannot control whether the CW signal is sent or not), then the Reader cannot construct a delimiter / OFF chip, thus preventing R2D transmission from being realized. This necessitates proposing a new signal transmission scheme.

[0090] In view of this, embodiments of this application provide a method for determining signal transmission parameters, a signal transmission method, a method for configuring signal transmission parameters, an apparatus, and a communication device to solve the related problems in the art caused by the transmission of CW signals not being controlled by the Reader.

[0091] The signal transmission parameter determination method and signal transmission parameter configuration method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0092] Figure 8 shows a flowchart of a signal transmission parameter determination method provided in an embodiment of this application. As shown in Figure 8, the signal transmission parameter determination method includes the following steps:

[0093] Step 801: The first device acquires the transmission parameters corresponding to the first signal, wherein the first signal includes a carrier excitation signal;

[0094] Step 802: The first device determines the transmission parameters corresponding to the second signal based on the transmission parameters corresponding to the first signal.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 predefined or configured transmission parameters corresponding to the first signal. 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 parameters corresponding to the first signal, the first device can know how the first signal is transmitted, and thus can determine the transmission parameters corresponding to the second signal based on the transmission parameters corresponding to the first signal, and transmit the second signal according to the transmission parameters corresponding to the second signal.

[0099] In this embodiment, a first device acquires transmission parameters corresponding to a first signal, where the first signal includes a carrier excitation signal. Based on the transmission parameters corresponding to the first signal, the first device determines transmission parameters corresponding to a second signal. Thus, by acquiring the transmission parameters corresponding to the first signal, the first device can determine the transmission parameters corresponding to the second signal, thereby enabling the transmission of the second signal.

[0100] In some embodiments, the first signal is sent by a third device, and the third device and the first device are different devices.

[0101] In other words, the signal transmission scheme of this application embodiment can be applied when the sending node of the first signal and the sending node of the second signal are not the same node.

[0102] It should be noted that the signal transmission scheme of this application embodiment can also be applied when the sending node of the first signal and the sending node of the second signal are the same node. This is because the sending node of the second signal also needs to send the first signal based on the transmission parameters corresponding to the first signal, and determine the transmission parameters of the second signal based on the transmission parameters corresponding to the first signal, and then send the second signal.

[0103] In some embodiments, at least some parameters of the transmission parameters corresponding to the first signal are predefined by a protocol; or,

[0104] At least some of the transmission parameters corresponding to the first signal are configured by network-side devices; or,

[0105] At least some of the transmission parameters corresponding to the first signal are configured by the first device.

[0106] In some embodiments, the method further includes:

[0107] The first device sends a first indication message to the network-side device, the first indication message being used to indicate the transmission parameters corresponding to the first signal that the first device wishes to configure.

[0108] The first instruction information can be either request information or auxiliary information. For example, the first device sends request information to the network-side device, which then configures the transmission parameters corresponding to the first signal based on the request information. The request information may or may not include R2D / D2R service-related information. As another example, the first device reports auxiliary information to the network-side device, which then configures the transmission parameters corresponding to the first signal based on the auxiliary information. The auxiliary information may or may not include R2D / D2R service-related information.

[0109] It should be noted that at least some of the parameters in the transmission parameters corresponding to the first signal can be configured by the network-side device, or at least some of the parameters in the transmission parameters corresponding to the first signal can be configured by the first device.

[0110] In some embodiments, the transmission parameters corresponding to the first signal include at least one of the following:

[0111] The first parameter includes at least one of the transmission time mode of the first signal and the transmission time resource of the first signal;

[0112] The second parameter includes the frequency resources of the first signal.

[0113] In one implementation, the first signal is transmitted in a specific transmission time pattern, or the first signal is transmitted on specific transmission time resources. In this implementation, the first device needs to know the transmission time pattern of the first signal, or the first device needs to know the transmission time resources of the first signal. Based on at least one of the transmission time pattern and transmission time resources, the first device can determine on which time resources the first signal is transmitted on and on which time resources it is not transmitted on. Thus, the first device can construct a delimiter / OFF chip on the time resources where the first signal is not transmitted, thereby enabling the transmission of the second signal. Alternatively, the first device can determine whether the transmission conditions of the second signal are met based on at least one of the transmission time pattern and transmission time resources, thus avoiding unnecessary processing when the transmission conditions of the second signal are not met.

[0114] It should be noted that, in one implementation, the transmission time mode of the first signal includes both mode information (such as periodic mode, aperiodic mode, or other specific modes) and the transmission time resources of the first signal under each mode (such as the transmission time resources of the first signal or the non-transmission time resources of the first signal). In this case, the first parameter is used to indicate the transmission time mode of the first signal. In another implementation, the transmission time mode of the first signal includes mode information but does not include the transmission time resources of the first signal under each mode. In this case, the first parameter can indicate both the transmission time mode and the transmission time resources of the first signal.

[0115] In another implementation, the first signal is transmitted using specific frequency domain resources. In this implementation, the first device needs to know the frequency domain resources of the first signal. The first device can determine the frequency domain resources of the second signal based on the frequency domain resources of the first signal, thereby enabling the transmission of the second signal.

[0116] In some embodiments, the transmission time pattern of the first signal includes at least one of the following:

[0117] In the first mode, the first signal is transmitted periodically with a first cycle.

[0118] In the second mode, the first signal is periodically transmitted in a second period, and within the second period, the first signal includes N sub-signals, which are transmitted 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.

[0119] In the third mode, the first signal includes M sub-signals, which are transmitted 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.

[0120] The first period, the second period, the duration or time interval of the sub-signals mentioned above can be determined by configuration or by predefinition.

[0121] The aforementioned aperiodic transmission can be understood as transmitting the first signal with independent (which may be unequal or partially unequal) time lengths and time intervals, which can be determined by predefinition or configuration.

[0122] In one implementation, the first signal is sent periodically. For example, the period T of the first signal is configured.

[0123] Optionally, the first signal is transmitted periodically with a first cycle, including at least one of the following:

[0124] There is a first offset between the start time of the first signal transmission within the first period and the start time of the first period;

[0125] There is a second offset between the end time of the first signal transmission within the first period and the end time of the first period;

[0126] The transmission time resource of the first signal within the first period is the first T1 time resource of the first period;

[0127] The transmission time resource of the first signal within the first period is the time resource after T2 of the first period.

[0128] For example, the period T of the first signal and the T at which the first signal begins to be transmitted within the period T. _offset1 T after the start time of each period T _offset1 Begin sending the first signal. For example, configure the period T of the first signal and the point T at which the first signal ends transmission within period T. _offset2 T before the end time of each period T _offset2 End the transmission of the first signal. For example, if the period T and transmission time resource T1 of the first signal are configured, by default, the first signal is transmitted within the first T1 time resources of each period T, and not transmitted within the subsequent (T-T1) time resources. For another example, if the period T and transmission time resource T2 of the first signal are configured, by default, the first signal is transmitted within the latter T2 time resources of each period T, and not transmitted within the first (T-T2) time resources.

[0129] In another implementation, the first signal is sent in a periodic pattern, or in other words, the first signal is sent periodically according to a certain pattern, with the first signal being sent aperiodically within each period. For example, the period of the configured pattern is T, and the first signal within period T includes two sub-signals. The first sub-signal is sent during time T1 within period T, then the first sub-signal is stopped during time T2 within period T, then the second sub-signal is sent during time T3 within period T, and then the second sub-signal is stopped during time T4 within period T, and the first signal is sent periodically according to the aforementioned pattern.

[0130] In another implementation, the first signal is sent with a specific non-periodic pattern. For example, the first signal includes three sub-signals: the first sub-signal is sent at time T1, then the first sub-signal is stopped at time T2, then the second sub-signal is sent at time T3, then the second sub-signal is stopped at time T4, then the third sub-signal is sent at time T5, and then the third sub-signal is stopped at time T6.

[0131] The transmission time pattern of the first signal can be configured by the network-side device, which then indicates the configured transmission time pattern to the first device. Alternatively, the transmission time pattern of the first signal can be predefined by the protocol. The transmission time pattern of the first signal can also be configured by the first device, or the first device can request configuration from the network-side device. This application embodiment does not limit this aspect.

[0132] In some embodiments, the transmission time resources of the first signal include at least one of the following:

[0133] The length of the non-transmission time resource of the first signal is greater than or equal to the length of the time resource required by the second signal.

[0134] The transmission time resource of the first signal is greater than or equal to the length of the time resource required by the third signal.

[0135] Here, the third signal can be found in the aforementioned explanation of the third signal; to avoid repetition, it will not be repeated here.

[0136] If the length of the non-transmission time resource of the first signal satisfies the above conditions, the length of the non-transmission time resource of the first signal satisfies the transmission time length required by the second signal, the second signal has the conditions for transmission, and thus the transmission of the second signal can be realized.

[0137] Accordingly, if the length of the transmission time resource of the first signal satisfies the above conditions, the length of the transmission time resource of the first signal satisfies the transmission time length required by the third signal, the third signal has the conditions for transmission, and thus the transmission of the third signal can be realized.

[0138] In some embodiments, the first device determines the transmission parameters corresponding to the second signal based on the transmission parameters corresponding to the first signal, including at least one of the following:

[0139] If the length of the non-transmission time resource of the first signal is greater than or equal to the length of the time resource required by the second signal, the first device determines the transmission parameters corresponding to the second signal.

[0140] The first device determines the transmission parameters corresponding to the second signal if the length of the transmission time resource of the first signal is greater than or equal to the length of the time resource required for the third signal.

[0141] Here, the third signal can be found in the aforementioned explanation of the third signal; to avoid repetition, it will not be repeated here.

[0142] If the length of the non-transmission time resource of the first signal meets the above conditions, the second signal is ready for transmission. In this case, the first device determines that the transmission parameters corresponding to the second signal are valid. The first device transmits the second signal only when the length of the non-transmission time resource of the first signal meets the required transmission time length of the second signal. This avoids unnecessary processing by the first device when the transmission conditions of the second signal are not met.

[0143] Accordingly, when the length of the transmission time resource of the first signal meets the above conditions, the third signal is ready for transmission. In this case, the first device determines that the transmission parameters corresponding to the second signal are valid. When the length of the transmission time resource of the first signal meets the required transmission time length for the third signal, the first device instructs the second device to transmit the third signal. This not only avoids unnecessary processing by the first device when the transmission conditions of the second signal are not met, but also avoids unnecessary processing by the second device when the transmission conditions of the third signal are not met.

[0144] In some embodiments, the transmission parameters corresponding to the second signal include at least one of the following:

[0145] The transmission time resources of the second signal;

[0146] The frequency resources of the second signal.

[0147] In some embodiments, the transmission time resources of the second signal include:

[0148] The transmission time resource of the second signal is located after the target time length following the end transmission time of the first signal;

[0149] Wherein, the target time length satisfies at least one of the following conditions:

[0150] The time length Tmin is greater than or equal to the time length Tmin, which is determined based on at least one of the minimum time length of the separator and the transmission time interval between the second signal and the third signal;

[0151] The time length Tmax is less than or equal to the time length Tmax, which is determined based on the maximum time length of the separator, and at least one of the transmission time interval between the second signal and the third signal.

[0152] Here, the third signal can be found in the aforementioned explanation of the third signal; to avoid repetition, it will not be repeated here.

[0153] In one example, the first time length is greater than or equal to the minimum time length of the separator, and less than or equal to the maximum time length of the separator. In another example, the first time length is greater than or equal to the minimum time length of the separator, and less than or equal to the maximum time length of the separator plus the maximum transmission time interval between the second and third signals. In yet another example, the first time length is greater than or equal to the minimum time length of the separator plus the minimum transmission time interval between the second and third signals, and less than or equal to the maximum time length of the separator. Many other cases are not listed here.

[0154] It should be noted that the values ​​or ranges of the minimum and maximum time lengths of the separator, the minimum and maximum transmission time intervals between the second and third signals, etc., can be predefined by the protocol or configured by the network-side equipment.

[0155] In some embodiments, the frequency resources of the first signal and the frequency resources of the second signal satisfy the following conditions:

[0156] The frequency resources of the first signal are different from those of the second signal.

[0157] When the frequency resources of the first signal and the second signal are different, the second device can receive the first signal and the second signal respectively through two matching networks or filters. In this way, the first signal will not affect the construction of the delimiter / off chip of the second signal. Thus, the transmission of the second signal can be achieved without considering the transmission time mode or transmission time resources corresponding to the first signal.

[0158] In one implementation, the frequency resources of the first signal and the frequency resources of the second signal are located in the same frequency band. That is, the first signal and the second signal use different frequency domain resources within the same frequency band.

[0214] Optionally, the frequency resources of the first signal and the frequency resources of the second signal are located in the same frequency band.

[0215] For related descriptions of the embodiments of this application, please refer to the descriptions of the method embodiments in Figures 8 and 9, which can achieve the same technical effects. To avoid repetition, they will not be described again.

[0216] To better understand the embodiments of this application, specific embodiments are provided below for illustrative purposes.

[0217] In the following embodiments, the explanation mainly focuses on signal transmission parameters. The first signal is a CW signal, the second signal is an R2D signal, and the third signal is a D2R signal. The first device is a Reader (or an Intermediate UE), the second device is a Tag, and the third device is a CW node.

[0218] Example 1: CW signal and R2D signal at different frequency positions

[0219] As shown in Figure 11, CW signals and R2D signals are transmitted using different frequency resources. For example, CW signals and R2D signals use different frequency resources within the same frequency band (such as the downlink (DL) spectrum of Frequency Division Duplex (FDD) or the uplink (UL) spectrum of FDD). CW signals are transmitted on frequency resource f1, and R2D signals containing delimiter / OFF chips are transmitted on frequency resource f2. f1 ≠ f2.

[0220] In this embodiment, the Tag receives the CW signal and the R2D signal respectively through two matching networks or filters, so that the CW signal does not affect the generation of the Delimiter / OFF chip of the R2D signal.

[0221] Example 2: CW signals are transmitted using a specific transmission time pattern.

[0222] CW signals can be transmitted periodically, for example, configuring the period T of the CW signal, and the starting point T of the CW signal transmission within period T. _offset T within each period T _offset Start sending CW signals. For example, as shown in Figure 12, configure the period T and transmission time T1 of the CW signal. By default, CW signals are sent during the first T1 time period of each period T, and no CW signals are sent during the subsequent (T-T1) time period.

[0223] CW signals can also be sent periodically according to a certain pattern. The transmission of CW signals within the pattern is non-periodic, as shown in Figure 13. The period of the pattern is 110ms. Within the pattern, CW signals are first sent for 30ms, then stopped for 20ms, then sent for 40ms, and then stopped for 20ms again. CW signals are sent periodically according to the aforementioned pattern.

[0224] The CW transmission time mode can be determined based on predefined rules, or the network-side device can configure the CW transmission time mode and instruct the Intermediate UE, or the Intermediate UE can request the network-side device to configure the corresponding CW transmission time mode for the CW node.

[0225] As shown in Figure 14, the Reader (or Intermediate UE) transmits signals to the Tag after a time T0 following the cessation of CW signal transmission. This includes, but is not limited to, transmission of Preamble, clock acquisition within Preamble, or R2D transmission. T0 is the delimiter time length, meaning that the OFF chip within the T0 time length is considered the delimiter. Furthermore, the value of T0 can be a time range, i.e., T0 is greater than or equal to the minimum value T. 0_min or less than or equal to the maximum value T 0_max T 0_min and T 0_max The value or range of values ​​can be predefined by the protocol or configured by the network-side device.

[0226] When determining the CW transmission time mode, it is necessary to ensure that the length of the non-transmission time resource of the CW signal within the transmission time mode can meet the transmission time of the R2D signal, so that the R2D signal can be transmitted normally; it is also necessary to ensure that the length of the transmission time resource of the CW signal within the transmission time mode can meet the transmission time of the D2R signal, so that the D2R signal can be transmitted normally.

[0227] Alternatively, the Reader may perform R2D transmission only when the length of the non-transmission time resource of the CW signal meets the transmission time of the R2D signal, thereby ensuring that the R2D signal can be transmitted normally; or the Reader may perform R2D transmission only when the length of the transmission time resource of the CW signal after the non-transmission time resource of the CW signal meets the transmission time of the D2R signal, thereby ensuring that the subsequent D2R can be transmitted normally.

[0228] In summary, the embodiments of this application provide a method for transmitting CW signals, which ensures that the transmission of CW signals does not affect the generation of the Delimiter / OFF chip of the R2D signal when the CW signal is sent by a CW node outside the Topology and the Reader inside the Topology cannot dynamically control the CW node to send or not send the CW signal.
