[0032] The following will be combined with the accompanying drawings in the embodiments of this application to clearly describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0033] The following describes the terms involved in the embodiments of the present application.

[0034] 1. Low-power Internet of Things (IoT) devices

[0035] A low-power IoT device is a type of IoT device that consumes relatively low power. For example, the device consumes relatively low power (less than or equal to a preset power consumption) when receiving signals and relatively low power when transmitting signals. Energy for such a device can come from the environment, such as wind energy, kinetic energy, thermal energy, or radio frequency (RF) signals. Such a device can also be referred to as an ambient IoT device, a passive IoT device, or a transponder.

[0036] Among them, the signal transmission method of the low-power IOT device can be to backscatter RF signals for signal transmission, such as electronic tags and radio frequency tags in low-power IOT devices; it can also be to actively generate signals and transmit signals, such as active tags in low-power IOT devices, but in order to achieve low power consumption of the device, the power of the signal generated by the active tag is lower than 0 decibel milliwatt dBm, such as less than or equal to -10dBm.

[0037] Regarding the signal transmission method of low-power IoT devices, taking electronic tags as an example, a simple implementation method is: when the electronic tag needs to send "1", the electronic tag reflects the incident RF signal, and when the electronic tag needs to send "0", the electronic tag does not reflect the incident RF signal. Here, the electronic tag can control the reflection coefficient Γ of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the incident signal to achieve signal modulation. The reflection coefficient of the signal can be represented as: Γ=(Z_1-Z_0) / (Z_1+Z_0)=|Γ|e ^ (jθ_T)

[0038] Where Z_0 is the antenna characteristic impedance, and Z_1 is the load impedance. Assuming the incident signal is S_in(t), the output signal is S_out(t) = s_in(t)|Γ|e^(jθ_T). Therefore, by properly controlling the reflection coefficient, corresponding amplitude modulation, frequency modulation, or phase modulation can be achieved.

[0039] Low-power IoT devices typically use low-power reception, typically using low-power RF, IF, or baseband envelope detection. The waveform of the transmitted signal typically uses simple modulation methods, such as on-off keying (OOK), amplitude shift keying (ASK), and frequency shift keying (FSK).

[0040] Furthermore, a device that communicates with a low-power IoT device is called a read-write device, which may be a terminal, a base station, or a device with read-write functions, such as a reader / writer, and the specifics are not limited here.

[0041] 2. Low power consumption wake-up receiving module

[0042] A low-power receiving module can be used for the wake-up function. The low-power wake-up receiving module can also be called a low-power wake-up receiver (LP WUR). The low-power receiving module is set in a low-power IoT device, and the low-power IoT device is also provided with a main communication module for sending and receiving mobile communication data.

[0043] In this way, when the low-power IoT device is in an energy-saving state, the low-power IoT device can turn on the low-power receiving module to listen for the low-power wake-up signal (LP-WUS) and turn off the main communication module (Main Radio, MR). When downlink data arrives, the sending device (such as a network-side device) will send the LP-WUS to the low-power IoT device. After the low-power IoT device listens to the LP-WUS through the low-power receiving module, it can turn on the main communication module and turn off the low-power receiving module. Among them, the low-power wake-up receiving module can be turned on continuously or intermittently. When the low-power wake-up receiving module is turned on, the low-power IoT device can receive the LP-WUS.

[0044] 3. LP-WUS

[0045] To reduce the amount of reception activity in low-power IoT devices while in standby mode, effectively shutting down the RF module and baseband (MODEM) module, significantly reducing power consumption during communication reception, a near-zero-power receiver can be introduced into the low-power IoT device's receiving module. This near-zero-power receiver eliminates the need for complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM module signal processing, relying solely on passive matched filtering and low-power signal processing. This allows network-side devices to trigger an on-demand wake-up signal, activating the near-zero-power receiver to receive notification of activation, thereby triggering a series of internal processes within the low-power IoT device, such as turning on the RF module and baseband module.

[0046] LP-WUS is generally a simple on-off keying signal, so that the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and recognition processes.

[0047] 4. Information transmission between reader and tag in Radio Frequency Identification (RFID)

[0048] Currently, the Ultra High Frequency (UHF) RFID protocol stipulates that in inventory mode, after the reader sends a query command (Query), the tag responds (Reply), that is, it generates a 16-bit random number to the reader, and then the reader sends the random number to the tag through an acknowledgment (ACK) command, and the tag sends the relevant data to the reader.

[0049] Among them, Table 1 shows the instructions for reader operation, and Table 2 shows the status of the tag. As shown in Tables 1 and 2:

[0050] Table 1 Reader / Writer Operation Instructions

[0051] Table 2 Label status

[0052] 5. Other terms

[0057] The signal transmission method, apparatus, receiving device, sending device and medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0058] Figure 2 shows a schematic flow chart of a signal transmission method provided by an embodiment of the present application. As shown in Figure 2, a signal transmission method provided by an embodiment of the present application may include the following steps 101 to 103.

[0059] Step 101: The sending device determines configuration information of N control signals according to target factors.

[0060] In some embodiments of the present application, the sending device may specifically be any one of the following: a network-side device, a terminal, an IoT device (such as a reader / writer), etc.

[0061] In an embodiment of the present application, the above-mentioned target factors include at least one of the following: channel quality of the frequency domain resource group, available frequency domain resources, and receiving capability of the receiving device.

[0062] In an embodiment of the present application, each of the above-mentioned N control signals is used to carry control information, and the control information is used to control the receiving device.

[0063] In some embodiments of the present application, the above-mentioned receiving device may be any one of the following: a low-power IoT device, a terminal, or other network-side devices (such as a base station).

[0064] In some embodiments of the present application, the configuration information may include at least one of the following:

[0065] The number of N frequency domain resource groups;

[0066] Indexes of N frequency domain resource groups;

[0067] Transmission parameters for transmitting control information on each frequency domain resource group;

[0068] A transmission mode of transmitting N control signals on N frequency domain resource groups.

[0069] In some embodiments of the present application, the above-mentioned transmission parameters may include at least one of the following: coding mapping mode, signal amplitude, power, phase, modulation mode, coding mode transmission rate, and bandwidth.

[0070] In some embodiments of the present application, the transmission mode may include any of the following: a repeated transmission mode and a multiplexed transmission mode. The repeated transmission mode may be a transmission mode in which a control signal is transmitted on each frequency domain resource group, and each control signal carries the same control information; the multiplexed transmission mode may be a transmission mode in which a control signal is transmitted on each frequency domain resource group, and each control signal carries different information parts of the same control information.

[0071] In some embodiments of the present application, when the target factor includes the channel quality of the frequency domain resource group, the transmitting device can first measure the channel quality of the channel corresponding to each frequency domain resource group in all the frequency domain resource groups (the all the frequency domain resource groups include N frequency domain resource groups), and determine the configuration information of N control signals based on the channel quality of the channel corresponding to each frequency domain resource group.

[0072] Optionally, if the channel quality of the channels corresponding to the frequency domain resource groups is better, the number N of frequency domain resource groups used for transmission is smaller to save resources; if the channel quality of the channels corresponding to the frequency domain resource groups is worse, the number N of frequency domain resource groups used for transmission is larger to improve transmission performance. The transmitting device may select, based on the number N of frequency domain resource groups used for transmission, the N frequency domain resource groups with the highest frequency domain positions from all frequency domain resource groups, or select the N frequency domain resource groups with the lowest frequency domain positions, or randomly select N frequency domain resource groups.

[0073] Optionally, if the channel quality of the channels corresponding to each frequency domain resource group is good, the transmission method for transmitting N control signals on N frequency domain resource groups can be a multiplexing transmission method to improve transmission efficiency; if the channel quality of the channels corresponding to each frequency domain resource group is poor, the transmission method for transmitting N control signals on N frequency domain resource groups can be a repeated transmission method to improve transmission performance.

[0074] In some embodiments of the present application, when the target factors include available frequency domain resources, the transmitting device may first determine the number of available frequency domain resources, and determine the configuration information of N control signals based on the number of available frequency domain resources.

[0075] Optionally, if the number of available frequency domain resources is greater, the number N of frequency domain resource groups used for transmission is greater to improve transmission performance; if the number of available frequency domain resources is smaller, the number N of frequency domain resource groups used for transmission is smaller to save resources.

[0076] In some embodiments of the present application, when the target factor includes the receiving capability of the receiving device, the transmitting device may first obtain the receiving capability of the receiving device from the receiving device, and determine the configuration information of N control signals based on the receiving capability of the receiving device.

[0077] Optionally, if the receiving capability of the receiving device is strong, the sending device can flexibly select the frequency domain resource group to determine N frequency domain resource groups, and the transmission method for transmitting N control signals on the N frequency domain resource groups can be a multiplexing transmission method to improve the transmission rate; if the receiving capability of the receiving device is weak, the sending device can select a predetermined frequency domain resource group to determine N frequency domain resource groups, and the transmission method for transmitting N control signals on the N frequency domain resource groups can be a repeated transmission method to improve the transmission performance.

[0078] It should be noted that the above-mentioned "receiving capability of the receiving device" can be understood as: the demodulation capability of the receiving device. It can be understood that the stronger the receiving capability of the receiving device, the lower the bit error rate when the receiving device transmits data.

[0079] For example, the receiving device in the embodiment of the present application may include a low-power IoT device, a tag, a terminal, etc. The receiving capability of the receiving device can be divided according to different device types.

[0080] For example, low-power IoT devices can be divided into OOK envelope detection receivers and orthogonal frequency division multiplexing (OFDM) receivers. For OOK envelope detection receivers, this type of receiver has poor reception performance and poor coverage, but is relatively power-saving. If you want to enhance coverage, you can use a repeated transmission scheme, that is, each control signal transmitted on N frequency domain resource groups carries a control information; for OFDM receivers, this type of receiver can distinguish between IQ two-way signals and has stronger demodulation capabilities, reception performance, and coverage performance than OOK envelope detection receivers, but is more power-consuming. At this time, multiplexing can be used to transmit at a higher rate.

[0081] For example, tags can be categorized as passive, semi-passive, and active. Passive tags lack energy storage capacitors or batteries and rely on RF signals for power (the received RF signal serves as the power source for the rectifier). They lack carrier generation capabilities and have the simplest circuitry, the lowest power consumption, and the worst decoding performance. Semi-passive tags have energy storage capacitors or batteries and rely on non-RF signals for power. They may also include power amplifiers, low-noise amplifiers, or other active devices. They lack carrier generation capabilities and have the lowest power consumption. Active tags have energy storage capacitors or batteries and rely on non-RF signals for power. They have carrier generation capabilities and can utilize more complex internal circuitry. They consume the most power but have the best reception performance.

[0082] In some embodiments of the present application, when the target factors include the channel quality of the frequency domain resource group, the available frequency domain resources, and the receiving capability of the receiving device, if the channel quality of the frequency domain resource group is good, the available frequency domain resources are sufficient, and the receiving capability of the receiving device is strong, then the transmission method for transmitting N control signals on N frequency domain resource groups may be a multiplexing transmission method to increase the transmission rate; if the channel quality of the frequency domain resource group is poor, the available frequency domain resources are insufficient, and the receiving capability of the receiving device is weak, then the transmission method for transmitting N control signals on N frequency domain resource groups may be a repeated transmission method.

[0083] In some embodiments of the present application, the sending device can directly determine all the configuration information of N control signals based on the target factors; or, the sending device can first determine part of the configuration information of N control signals based on the target factors, and then determine another part of the configuration information of N control signals based on part of the configuration information of the N control signals.

[0084] In an embodiment of the present application, the frequency domain resource group includes at least one frequency domain resource, and N is a positive integer.

[0085] In some embodiments of the present application, for each frequency domain resource group in the N frequency domain resource groups, one frequency domain resource group includes each frequency domain resource in a frequency domain segment on the frequency domain resource.

[0086] In some embodiments of the present application, the frequency domain resources may specifically be resource elements (REs). For each of the N frequency domain resource groups, the REs included in a frequency domain resource group may be continuous in the frequency domain.

[0087] In some embodiments of the present application, different frequency domain resource sets have different resource parameters, and the resource parameters include at least one of the following: the number of included frequency domain resource groups, the frequency domain position of the included frequency domain resource groups, and the size of the frequency domain resources occupied by the included frequency domain resource groups.

[0088] Optionally, the N frequency domain resource groups may belong to the same frequency domain resource set, i.e., M=1; or, some of the N frequency domain resource groups belong to one frequency domain resource set, and the other part of the frequency domain resource groups belong to another frequency domain resource set, i.e., M<N; or, each of the N frequency domain resource groups belongs to a frequency domain resource set, i.e., M=N.

[0089] For example, Figure 3 shows a schematic diagram of N frequency domain resource groups. As shown in Figure 3, the N frequency domain resource groups may include Seg#0, Seg#1, Seg#2, and Seg#3; wherein Seg#0, Seg#1, Seg#2, and Seg#3 may belong to one frequency domain resource set, such as AL#4. Alternatively, Seg#0 and Seg#1 may belong to one frequency domain resource set, such as AL#21, and Seg#2 and Seg#3 may belong to another frequency domain resource set, such as AL#22. Alternatively, Seg#0 may belong to one frequency domain resource set, such as AL#11, Seg#1 may belong to another frequency domain resource set, such as AL#12, Seg#2 may belong to yet another frequency domain resource set, such as AL#13, and Seg#3 may belong to yet another frequency domain resource set, such as AL#14.

[0090] In some embodiments of the present application, the indexes of the N frequency domain resource groups may be continuous or discontinuous indexes. The index of the frequency domain resource group may be a sequence number obtained by sorting the N frequency domain resource groups according to their frequency domain positions. The index of the frequency domain resource group may satisfy any of the following conditions: determined by the transmitting device, agreed upon by the protocol, or predefined.

[0091] In some embodiments of the present application, the configuration information of the control signal received on adjacent frequency domain resource groups among N frequency domain resource groups is different; wherein, the above-mentioned adjacent frequency domain resource groups are any one of the following: frequency domain resource groups adjacent in the frequency domain, and frequency domain resource groups adjacent in the same frequency domain resource set.

[0092] In an embodiment of the present application, if each control signal carries a control information, it may cause the Peak to Average Power Ratio (PAPR) of the transmitting device to become higher. Therefore, the transmitting device can use different transmission parameters for different frequency domain resource groups to reduce the PAPR.

[0093] In some embodiments of the present application, the configuration information includes the indexes of the N frequency domain resource groups and the transmission parameters for transmitting control information on each frequency domain resource group. Optionally, in combination with Figure 2, as shown in Figure 4, the above step 101 can be specifically implemented through the following steps 101a and 101b.

[0094] Step 101a: The sending device determines the indexes of N frequency domain resource groups according to target factors.

[0095] In some embodiments of the present application, the transmitting device may first determine the number N of frequency domain resource groups used for transmission based on target factors, and then determine the indexes of the N frequency domain resource groups based on the number N of frequency domain resource groups used for transmission.

[0096] It should be noted that, for the description of how the transmitting device determines the indexes of N frequency domain resource groups based on the number N of frequency domain resource groups used for transmission, reference can be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0097] Step 101b: The sending device determines the transmission parameters corresponding to each frequency domain resource group according to the index of the N frequency domain resource groups.

[0098] In some embodiments of the present application, the above-mentioned transmission parameters may include at least one of the following: coding mapping mode, signal amplitude, power, phase, modulation mode, coding mode transmission rate, and bandwidth.

[0099] In some embodiments of the present application, the transmitting device may determine the transmission parameters corresponding to each frequency domain resource group according to the parity of the indexes of the N frequency domain resource groups.

[0100] Optionally, when the above-mentioned transmission parameters include a coding mapping mode, among the N frequency domain resource groups, the coding mapping modes corresponding to the frequency domain resource groups with odd indexes and the frequency domain resource groups with even indexes may be opposite.

[0101] Exemplarily, assuming that the above-mentioned transmission parameter is a coding mapping mode, the transmitting device can determine the coding mapping mode corresponding to the frequency domain resource group with an even index in the N frequency domain resource groups as a first mapping mode, and determine the coding mapping mode corresponding to the frequency domain resource group with an odd index in the N frequency domain resource groups as a second mapping mode, and the second mapping mode and the first mapping mode can be opposite. For example, when the first mapping mode is adopted, 1 can be mapped to {0,1}, and 0 can be mapped to {1,0}, and when the second mapping mode is adopted, 1 can be mapped to {1,0}, and 0 can be mapped to {0,1}, or, when the first mapping mode is adopted, 1 can be mapped to {-1,1}, and 0 can be mapped to {1,-1}, and when the second mapping mode is adopted, 1 can be mapped to {1,-1}, and 0 can be mapped to {-1,1}.

[0102] For example, Figure 5 shows a schematic diagram of transmission parameters corresponding to N frequency domain resource groups determined by a transmitting device. As shown in Figure 5, the N frequency domain resource groups may include Seg#0, Seg#1, Seg#2, and Seg#3. The transmitting device transmits a control message on each of Seg#0, Seg#1, Seg#2, and Seg#3. Thus, the transmitting device can determine the transmission parameters (e.g., coding mapping method) corresponding to each frequency domain resource group based on the parity of the indexes of Seg#0, Seg#1, Seg#2, and Seg#3. For example, the sequence mapped on Seg#0 is {0101…}, the sequence mapped on Seg#1 is {1010…}, the sequence mapped on Seg#2 is {0101…}, and the sequence mapped on Seg#3 is {1010…}. It can be understood that the same information (i.e., the above-mentioned control information) is transmitted on Seg#0 and Seg#1, but different coding mapping methods are used. Therefore, the sequence mapped on Seg#0 is completely different from the sequence mapped on Seg#1; the same information (i.e., the above-mentioned control information) is transmitted on Seg#2 and Seg#3, but different coding mapping methods are used. Therefore, the sequence mapped on Seg#2 is completely different from the sequence mapped on Seg#3.

[0103] It can be seen that since the transmitting device can determine the transmission parameters corresponding to each frequency domain resource group based on the index of N frequency domain resource groups, and the transmission parameters corresponding to adjacent frequency domain resource groups in the frequency domain or adjacent frequency domain resource groups in the same frequency domain resource set are different, the PAPR of the transmitting device can be reduced.

[0104] Step 102: The sending device sends N control signals on N frequency domain resource groups according to the configuration information of the N control signals.

[0105] In an embodiment of the present application, each of the above-mentioned N control signals corresponds to a frequency domain resource group, and the control signal is used to carry control information, and the control information is used to control the receiving device.

[0106] It can be understood that the transmitting device can send a control signal on each frequency domain resource group respectively.

[0107] In some embodiments of the present application, when the above-mentioned configuration information includes the indexes of N frequency domain resource groups, the above-mentioned N frequency domain resource groups are the frequency domain resource groups indicated by the indexes of the N frequency domain resource groups; when the above-mentioned configuration information does not include the indexes of N frequency domain resource groups, the above-mentioned N frequency domain resource groups can be the frequency domain resource groups selected by the transmitting device from all frequency domain resource groups.

[0108] It should be noted that, for the description of the transmitting device selecting N frequency domain resource groups from all frequency domain resource groups, reference may be made to the specific description in the above embodiment, and the embodiments of the present application will not be repeated here.

[0109] In some embodiments of the present application, the transmitting device may send a control signal to the receiving device using a frequency domain resource set as a unit.

[0110] Optionally, the transmitting device may determine the number M of M frequency domain resource sets based on the above target factors to determine N frequency domain resource groups, so that the transmitting device can send N control signals on the N frequency domain resource groups.

[0111] For example, when the wireless network environment quality is good, the transmitting device may determine the number M of the M frequency domain resource sets to be 1, and the one frequency domain resource set includes at least one frequency domain resource group, that is, the N frequency domain resource groups are the at least one frequency domain resource group, so that the transmitting device can send a control signal to the receiving device on the one frequency domain resource group to save resources, or send at least two control signals on at least two frequency domain resource groups, and each control signal carries different information parts of the same control information, so as to improve the transmission rate. Alternatively, when the wireless network environment quality is poor, the transmitting device may determine the number M of the M frequency domain resource sets to be at least two, and each frequency domain resource set includes at least one frequency domain resource group, so as to determine multiple frequency domain resource groups, that is, the N frequency domain resource groups are the multiple frequency domain resource groups, so that the transmitting device can send multiple control signals on the multiple frequency domain resource groups to ensure the performance of control information transmission.

[0112] The transmitting device can modulate each frequency domain resource group in the following manner: the transmitting device can modulate the frequency domain information within each frequency domain resource group so that each frequency domain resource group presents a square wave shape in the time domain, thereby allowing each frequency domain resource group to carry multiple bits of information in the time domain. Using this method, the size of the transmitted frequency domain resources can be modulated according to actual conditions. The frequency domain information can include at least one of the following: frequency shift information, phase change information, etc.

[0113] In some embodiments of the present application, the control signal may be modulated by OOK, ASK, or FSK. The control signal includes at least one of the following: high-level signaling, a wake-up signal, and a periodic signal.

[0114] In some embodiments of the present application, when the transmitting device is a reader / writer and the receiving device is an IoT device, the control signal may be any of the following: a Select signal, a Query signal, a Request signal, etc. The Select signal is used to indicate a tag selection operation, the Query signal is used to perform a Query operation, and the Request signal is used to perform a Request operation.

[0115] In some embodiments of the present application, the wake-up signal may be an LP-WUS, which may be used to wake up a main communication module of a receiving device. The periodic signal may include any of the following: a beacon signal or a low-power synchronization signal (LP-SS); the beacon signal or LP-SS is a signal used to transmit time information, and the receiving device may obtain time synchronization information by receiving the beacon signal or LP-SS.

[0116] In some embodiments of the present application, each control signal carries a control information; or, each control signal carries different information parts of the same control information.

[0117] Optionally, in the case where each control signal carries a piece of control information, each of the N control signals is self-decodable.

[0118] In an embodiment of the present application, if each control signal carries a control information, it can be considered that the sending device repeatedly sends N control signals to the receiving device. In this way, the receiving device can decode the control information when it receives a signal on any frequency domain resource group, thereby improving the transmission capacity of the control information.

[0119] Optionally, the above-mentioned information part may be information bits of a control information, and the bits of this part may be encoded bits, or may be bits before encoding.

[0120] Exemplarily, assuming that N control signals include control signal 1 and control signal 2, the control signal 1 can carry an information part of a control information, such as 1 to 50 bits, and the control signal 2 can carry another information part of the control information, such as 51 to 100 bits.

[0121] It can be understood that in this example, after the transmitting device sends N control signals, the receiving device needs to receive signals on all frequency domain resource groups before it can decode the control information.

[0122] In an embodiment of the present application, if each control signal carries different information parts of the same control information, it can be considered that the sending device sends one control information through N control signals. Therefore, the sending device can send more control information bits; or, more complex encoding can be used to send the encoded bits on N control signals to improve the performance of control information transmission.

[0123] Step 103: The receiving device receives N control signals on N frequency domain resource groups according to the configuration information of the N control signals.

[0124] In an embodiment of the present application, the above-mentioned configuration information is determined by the sending device based on the target factors, and the target factors include at least one of the following: the channel quality of the frequency domain resource group, the available frequency domain resources, and the receiving capability of the receiving device; the frequency domain resource group includes at least one frequency domain resource, and N is a positive integer greater than 1.

[0125] In some embodiments of the present application, the configuration information includes at least one of the following:

[0126] The number of N frequency domain resource groups;

[0127] Indexes of N frequency domain resource groups;

[0128] Transmission parameters for transmitting control information on each frequency domain resource group;

[0129] A transmission mode of transmitting N control signals on N frequency domain resource groups.

[0130] In some embodiments of the present application, N frequency domain resource groups belong to M frequency domain resource sets, where M is a positive integer less than or equal to N; wherein, different frequency domain resource sets have different resource parameters, and the resource parameters include at least one of the following: the number of included frequency domain resource groups, the frequency domain position of the included frequency domain resource groups, and the size of the frequency domain resources occupied by the included frequency domain resource groups.

[0131] In some embodiments of the present application, the configuration information of the control signal received on adjacent frequency domain resource groups among N frequency domain resource groups is different; wherein, the above-mentioned adjacent frequency domain resource groups are any one of the following: frequency domain resource groups adjacent in the frequency domain, and frequency domain resource groups adjacent in the same frequency domain resource set.

[0132] In some embodiments of the present application, the above-mentioned control signal includes at least one of the following: a beacon signal, a high-layer signaling, a control signal, and a periodic signal.

[0133] In some embodiments of the present application, each control signal carries a control information; or, each control signal carries different information parts of the same control information.

[0134] An embodiment of the present application provides a signal transmission method, in which a sending device may first determine configuration information of N control signals based on target factors, where the control signals are used to carry control information, and the control information is used to control a receiving device, where the target factors include at least one of the channel quality of a frequency domain resource group, available frequency domain resources, and the receiving capability of the receiving device, and the N control signals are sent on N frequency domain resource groups according to the configuration information of the N control signals, where each control signal corresponds to a frequency domain resource group, so that the receiving device can receive the N control signals on the N frequency domain resource groups according to the configuration information of the N control signals; wherein the frequency domain resource group includes at least one frequency domain resource, and N is a positive integer greater than 1. Since the transmitting device can determine the configuration information for sending at least two control signals based on the channel quality of the frequency domain resource group, so as to send the at least two control signals on at least two frequency domain resource groups according to the configuration information of the at least two control signals, instead of sending the control signal on only one frequency domain resource group, in this way, when the channel quality of one frequency domain resource group is poor, even if the receiving device cannot receive the control signal on the one frequency domain resource group, it can still receive the control signal on other resource groups of the at least two frequency domain resource groups except the one frequency domain resource group, thereby avoiding the situation where the receiving device cannot receive the control signal; and / or, the transmitting device can determine the configuration information for sending at least two control signals based on the available frequency domain resources, so as to send the at least two control signals on at least two frequency domain resource groups according to the configuration information of the at least two control signals, Therefore, the situation in which the receiving device is unable to receive the control signal due to the conflict between the frequency domain resources of at least two frequency domain resource groups and other signals can be avoided; and / or, the sending device can determine the configuration information for sending at least two control signals based on the receiving capability of the receiving device, so as to send the at least two control signals on at least two frequency domain resource groups according to the configuration information of the at least two control signals. Therefore, for devices with weak receiving capabilities, the situation in which the control signal cannot be received due to insufficient receiving capability of the receiving device can be avoided, and for devices with strong receiving capabilities, the data transmission rate can be improved; thereby, the receiving device can quickly execute the operation corresponding to the control information carried by the control signal, and thus can improve the data transmission rate of the receiving device while avoiding the situation in which the receiving device is unable to communicate with other devices, thereby improving the communication quality of the receiving device.

[0135] Of course, since the number of frequency domain resource groups, and / or indexes, and / or transmission parameters for transmitting control information on each frequency domain resource group, and / or the transmission method for transmitting N control signals on N frequency domain resource groups are flexibly determined by the transmitting device, the receiving device can perform detection on multiple frequency domain resource groups at the same time to avoid missing the control signal, which will be explained with examples below.

[0136] In some embodiments of the present application, the signal transmission method provided in the embodiments of the present application may further include the following steps 201 to 203.

[0137] Step 201: A sending device sends N target signals on N frequency domain resource groups.

[0138] In an embodiment of the present application, each of the above-mentioned N target signals corresponds to a frequency domain resource group, and the target signal is used to indicate the configuration information of N control signals; the target signal is any one of the following: the first part of the control signal, the first part of the signal sent by the sending device.

[0139] It can be understood that the transmitting device can send a target signal on each frequency domain resource group in the N frequency domain resource groups.

[0140] In the embodiment of the present application, the signal sent by the above-mentioned sending device can be understood as: a signal that the sending device has sent to the receiving device before sending the control signal.

[0141] Optionally, the signal sent by the sending device may be any one of the following: a selection signal, a query signal, a higher-layer signaling, etc. The higher-layer signaling may be any one of the following: downlink control information (DCI), radio resource control (RRC) information, etc.

[0142] In the embodiment of the present application, the structure of the signal transmitted by the transmitting device on each frequency domain resource group (i.e., the time domain signal structure) may include at least one of the following: a signal sequence portion, an information bit portion, and a cyclic redundancy check (CRC) portion of the information bit. The signal sequence portion may be used for synchronization, and the information bit portion may be used to carry coded or uncoded information.

[0143] For example, Figure 6 shows a schematic diagram of the time domain signal structure of a signal transmitted by a transmitting device on a frequency domain resource group. As shown in Figure 6, the time domain signal structure of the signal transmitted by the transmitting device on a frequency domain resource group may include: a signal sequence portion, an information bit portion, and a CRC portion of the information bit portion.

[0144] In some embodiments of the present application, the first part includes at least one of the following:

[0145] target sequence;

[0146] target bit;

[0147] CRC bits of the target bits.

[0148] It is understood that the target sequence may be a sequence portion of a control signal or a sequence portion of a signal already sent by the transmitting device. The target bit may be an information bit portion of a control signal or an information bit portion of a signal already sent by the transmitting device.

[0149] In some embodiments of the present application, at least one of the target sequence, target bit, and CRC bit of the target bit is used to carry configuration information of N control signals.

[0150] In some embodiments of the present application, the first part may satisfy any of the following conditions: being a predefined part, or being a part agreed upon in the protocol.

[0151] In some embodiments of the present application, the sending device may first determine the configuration information of N control signals based on the above-mentioned target factors, and then determine the target signal based on the configuration information of the N control signals, so that the sending device can send N target signals to indicate the configuration information of N control signals to the receiving device.

[0152] Optionally, after the transmitting device determines the configuration information of the N control signals, the transmitting device may determine a target value corresponding to the configuration information according to a target table, and determine a target signal according to the target value. The target table includes multiple correspondences, each of which is a correspondence between one configuration information and one value.

[0153] For example, Table 3 shows a target table, as shown in Table 3:

[0154] Table 3

[0155] The configuration information of the N control signals includes the number of N frequency domain resource groups (i.e., the frequency domain resource group in Table 3), the index of the N frequency domain resource groups (i.e., the frequency domain resource index in Table 3), the transmission parameters for transmitting the control information on each frequency domain resource group (i.e., the coding mode, transmission parameter, multiple bits per symbol, BW size, and modulation mode in Table 3), and the transmission mode for transmitting the N control signals on the N frequency domain resource groups (i.e., the multiplexing transmission mode or the repetition transmission mode in Table 3). Therefore, the transmitting device can determine the configuration information of the N control signals based on the above target factors, and use the target table to determine the target value corresponding to the configuration information of the N control signals (i.e., the Index in Table 3), and determine the target signal based on the target value, so that the transmitting device can send the N target signals on the N frequency domain resource groups.

[0156] For example, when the first part is a target sequence, the sending device may determine the target value corresponding to the configuration information of the N control signals using a target table (i.e., the Index in Table 3), and then directly determine the target value as the content of the target sequence. Alternatively, the sending device may determine the target value as the length of the target sequence.

[0157] For example, when the first part is a target bit, the sending device may carry the target value directly on the target bit after using the target table to determine the target value corresponding to the configuration information of the N control signals (ie, the Index in Table 3).

[0158] For example, when the first part is the CRC bit of the target bit, the transmitting device uses the target table to determine the target value corresponding to the configuration information of the N control signals (i.e., the index in Table 3), and then directly carries the target value in the CRC bit of the target bit. For example, different CRC parameters carry different values.

[0159] It should be noted that the above-mentioned "different CRC parameters" can be understood as: using a predefined or configured scrambling sequence to scramble the CRC, for example, using <0,0,…0>, <0,0,…,1> to indicate the distinction of control commands of different formats; or, using different CRC generating polynomials for distinction, for example, the CRC generating polynomial for the control command of configuration 1 is x^15+x^11+x^10+x^7+x^4+x^2+x+1; the CRC generating polynomial for the control command of configuration 2 is x^15+x^13+x^9+x^8+x^6+x^3+x+1; the length of these two CRCs is both 16 bits. Different formats may also correspond to CRCs of different lengths. For example, the CRC generating polynomial for the control command of configuration 1 is x^15+x^11+x^10+x^7+x^4+x^2+x+1; the CRC generating polynomial for the control command of configuration 2 is x^7+x^6+x^3+x+1; the former is a CRC with a length of 16 bits, and the latter is a CRC with a length of 8 bits.

[0160] It should be noted that the coding in Table 3 may include a coding method and a code rate corresponding to the coding method; the coding method may include any of the following: Miller code, FM0 code, Manchester code, Walsh code, polar code, block code, etc. The frequency domain resource group in Table 3 refers to the number of frequency domain resource groups. For example, frequency domain resource group = 4 means that the frequency domain is divided into 4 frequency domain resource groups. The frequency domain resource index in Table 3 refers to the index of the frequency domain resource group, and its position can be represented by a bitmap. For example, when frequency domain resource group = 4, frequency domain resource index = [1, 0, 0, 1], which means that the two frequency domain resource groups with the lowest and highest indexes are transmitting information, such as AL#11 and AL#14 in Figure 3. The "Per bit in one symbol" in Table 3 can be 1, 2, 4, 8, etc., indicating the number of bits transmitted on an Orthogonal Frequency Division Multiplexing (OFDM) symbol. It can also directly indicate the transmission rate (data rate, communication link rate: different time units and reverse link basic clock cycle parameters). The "BW size" in Table 3 can be 4.32M, 2.16M, etc., set for different coverage levels. The "multiplexing" or "repetition" in Table 3 can be 1 or 0, for example, 1 represents multiplexing transmission mode and 0 represents repetition transmission mode. The "Modulation" in Table 3 can be OOK, ASK, etc.

[0161] In some embodiments of the present application, the target table may satisfy any one of the following conditions: configured by the sending device, predefined, or agreed upon by the protocol.

[0162] It should be noted that the embodiment of the present application does not limit the execution order of step 201 and step 101; in one example, when the target signal is the first part of the signal received by the receiving device, step 201 can be executed first and then step 101; in another example, when the target signal is the first part of the control signal, step 101 can be executed at the same time as step 201.

[0163] Step 202: The receiving device detects target signals on L frequency domain resource groups.

[0164] In an embodiment of the present application, the above-mentioned target signal is used to indicate configuration information of N control signals, and L is a positive integer.

[0165] It can be understood that the receiving device may first detect the target signal on L frequency domain resource groups to obtain configuration information of N control signals.

[0166] In the embodiment of the present application, the above-mentioned target signal is any one of the following: the first part of the control signal, the first part of the signal sent by the sending device.

[0167] In some embodiments of the present application, the first part includes at least one of the following:

[0168] target sequence;

[0169] target bit;

[0170] CRC bits of the target bits.

[0171] In some embodiments of the present application, the configuration information includes at least one of the following:

[0172] The number of N frequency domain resource groups;

[0173] Indexes of N frequency domain resource groups;

[0174] Transmission parameters for transmitting control information on each frequency domain resource group;

[0175] A transmission mode of transmitting N control signals on N frequency domain resource groups.

[0176] Step 203: The receiving device determines the configuration information of N control signals according to the detection result of the target signal.

[0177] In some embodiments of the present application, when a receiving device detects a target signal from any one of L frequency domain resource groups, the receiving device can determine the configuration information of N control signals based on the target signal; in this way, the receiving device can determine the N frequency domain resource groups, and / or the transmission parameters for transmitting control information on each frequency domain resource group, and / or the transmission method for transmitting N control signals on the N frequency domain resource groups, and based on the N frequency domain resource groups, and / or the transmission parameters for transmitting control information on each frequency domain resource group, and / or the transmission method for transmitting N control signals on the N frequency domain resource groups, decode the N control signals to obtain control information.

[0178] Optionally, the receiving device may determine the configuration information of the N control signals based on the frequency domain resource group in which the target signal is detected; or the receiving device may use the target table to determine the configuration information of the N control signals corresponding to the target signal. The target table may satisfy any of the following conditions: configured by the transmitting device, predefined, or agreed upon by the protocol.

[0179] In which case, when the first part is a target sequence, the receiving device may first determine a target value based on the content or length of the target sequence, and then determine the configuration information of N control signals corresponding to the target value from the target table.

[0180] In the case where the first part is a target bit, the receiving device may first decode the target bit to obtain a target value, and then determine the configuration information of N control signals corresponding to the target value from the target table.

[0181] It can be seen that since the sending device can send N target signals on N frequency domain resource groups, each target signal is the first part of the control signal, or the first part of the signal sent by the sending device, to indicate the configuration information of N control signals to the receiving device, this can avoid the receiving device from being unable to receive the configuration information of N control signals due to an unstable wireless network environment, while eliminating the need to send additional signals carrying the configuration information of the N control signals to the receiving device. Therefore, it can avoid the receiving device from blindly detecting N control signals while saving transmission resources.

[0182] In some embodiments of the present application, the configuration information includes indexes of the N frequency domain resource groups. Optionally, step 203 may be implemented through step 203a or step 203b described below.

[0183] Step 203a: The receiving device determines the index of the frequency domain resource group where the target signal is detected as the index of N frequency domain resource groups.

[0184] In an embodiment of the present application, since the receiving device is not clear about the number of resources actually used by the current sending device, that is, the receiving device is not sure about the indexes of the N frequency domain resource groups, the receiving device can first perform detection on L frequency domain resource groups (that is, all frequency domain resource groups), that is, the receiving device can first detect the target signal. If the target signal is detected, it is considered that the control signal has been sent, and subsequent control information monitoring, decoding, etc. are performed on the frequency domain resource group; if the receiving device detects target signals on multiple frequency domain resource groups, control information detection and decoding are performed on the multiple frequency domain resource groups; for example, the control information on multiple frequency domain resource groups can be jointly detected and decoded.

[0185] Step 203b: The receiving device determines M frequency domain resource sets related to the target signal according to the detected target signal, and determines the indexes of the frequency domain resource groups in the M frequency domain resource sets as the indexes of the N frequency domain resource groups.

[0186] In the embodiment of the present application, the above-mentioned N frequency domain resource groups belong to M frequency domain resource sets, where M is a positive integer less than or equal to N.

[0187] In some embodiments of the present application, the target signal is related to at least one of the following items in the M frequency domain resource sets: the number of frequency domain resource groups; and the index of the frequency domain resource group.

[0188] In the embodiments of the present application, the target signal transmitted on each frequency domain resource group can be used to indicate the frequency domain resource set occupied by the control signal transmission, the number of frequency domain resource groups, and the index of the frequency domain resource group. Thus, different target signals correspond to different frequency domain resource sets, the number of frequency domain resource groups, and the index of the frequency domain resource group. Therefore, a receiving device can determine the occupancy of the frequency domain resource group or frequency domain resource set based on the detected target signal.

[0189] Furthermore, since the receiving device detects the target signal on any frequency domain resource group, it can determine the number of N occupied frequency domain resource groups, and / or the index, and / or the transmission parameters for transmitting control information on each frequency domain resource group, and / or the transmission method for transmitting N control signals on N frequency domain resource groups.
