Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information sending method, processing method, device and equipment. Background Art

[0002] To support the interconnection of hundreds of billions of devices, address the high network construction costs associated with large-scale IoE deployments, and address the high operational costs associated with ongoing maintenance, such as battery replacement, a new type of Internet of Things (IoT) device, the Ambient IoT (AIoT), has been designed into 5G systems. AIoT devices have limited or no energy storage capabilities and are characterized by low complexity, low cost, and low power consumption, contributing to the realization of the perception and interconnection of everything.

[0003] For 5G AIoT communication systems, there may be multiple different types of AIoT devices with different capabilities coexisting. Currently, AIoT devices can be divided into the following two types:

[0004] Type 1 devices: Peak power consumption is approximately 1 μW, with energy storage capability and an initial sampling frequency offset (SFO) of up to 10 X ppm, the device has neither downlink (DL) nor uplink (UL) amplification capabilities. The device's UL transmission is backscattered on an externally provided carrier.

[0005] Type II devices: peak power consumption ≤ several hundred μW, with energy storage capability, and initial sampling frequency offset (SFO) up to 10 X ppm, the device has DL and / or UL amplification capabilities. The device's UL transmission can be generated internally by the device or backscattered on an externally provided carrier.

[0006] Existing technologies only specify communication links between base stations and wireless communication terminals with strong storage capabilities and high complexity. They do not define communication links between base stations and AIoT devices with no or very limited energy storage capabilities. In other words, existing technologies do not specify how information is transmitted between other communication entities and AIoT devices. Summary of the Invention

[0234] like Figure 2 As shown, an embodiment of the present application provides a method for sending information, the method comprising:

[0235] Step 201: A first communication entity sends a first-level first bearer and a second-level first bearer.

[0236] The first-level first carrier carries at least one of the following information:

[0237] Device activation or deactivation information, uplink transmission resource information, carrier transmission resource information, resource information of the second-level first carrier, device identification information, source node identifier information of the first carrier, device type information, reporting information type indication, backscatter air interface protocol type indication information, broadcast type information, uplink transmission modulation information, uplink transmission coding information, priority information;

[0238] The second-level first carrier carries at least one of the following information:

[0239] Device activation or deactivation information, uplink transmission resource information, carrier transmission resource information, device identification information, source node identifier information of the first carrier, device type information, reporting information type indication, backscatter air interface protocol type indication information, broadcast type information, uplink transmission modulation information, uplink transmission coding information, priority information.

[0240] In one implementation, the devices mentioned in the embodiments of the present application are specifically referred to as AIoT devices; optionally, AIoT devices can be divided into the following two types:

[0241] Type 1 devices: Peak power consumption is approximately 1 μW, with energy storage capability and an initial sampling frequency offset (SFO) of up to 10 X ppm, the device has neither downlink (DL) nor uplink (UL) amplification capabilities. The device's UL transmission is backscattered on an externally provided carrier.

[0242] Type II devices: peak power consumption ≤ several hundred μW, with energy storage capability, and initial sampling frequency offset (SFO) up to 10 X ppm, the device has DL and / or UL amplification capabilities. The device's UL transmission can be generated internally by the device or backscattered on an externally provided carrier.

[0243] In another implementation, the first communication entity includes a base station, a terminal, or an intermediate node, which is not specifically limited here.

[0244] It should be noted that in the embodiment of the present application, the first carrier is divided into two levels, that is, the first communication entity sends the first-level first carrier and the second-level first carrier; alternatively, in the embodiment of the present application, the first carrier is divided into M levels, where M is an integer greater than 2; for example, when M is equal to 3, the first communication entity sends the first-level first carrier, the second-level first carrier, and the third-level first carrier; for another example, when M is equal to 4, the first communication entity sends the first-level first carrier, the second-level first carrier, the third-level first carrier, and the fourth-level first carrier. M can also be equal to 5, or equal to 6, etc., which are not enumerated here.

[0245] Optionally, in the case of including M-level first carriers, the first-level first carrier, the second-level first carrier, ..., the M-th-level first carrier carry at least one of the following information:

[0246] Device activation or deactivation information, uplink transmission resource information, carrier transmission resource information, device identification information, source node identifier information of the first carrier, device type information, reporting information type indication, backscatter air interface protocol type indication information, broadcast type information, uplink transmission modulation information, uplink transmission coding information, priority information.

[0247] Optionally, the M-1th level first bearer also carries resource information of the Mth level first bearer.

[0248] As an optional embodiment, the uplink transmission resource information includes: at least one of uplink transmission time domain resource information, uplink transmission frequency domain resource information, and uplink transmission resource reservation period information.

[0249] And / or, as another optional embodiment, the carrier transmission resource information includes: at least one of carrier transmission time domain resource information, carrier transmission frequency domain resource information, and carrier transmission resource reservation period information;

[0250] And / or, as another optional embodiment, the resource information of the second-level first bearer includes: at least one of: time domain resource information of the second-level first bearer, frequency domain resource information of the second-level first bearer, and resource reservation period information of the second-level first bearer;

[0251] And / or, as another optional embodiment, the device identification information includes: at least one of device identifier information, device group identifier information, and device type identifier information.

[0252] Optionally, the first carrier comprises at least one of the following:

[0253] Downlink query signal;

[0254] Downlink query channel;

[0255] Signals for Ambient IoT;

[0256] A channel for the Ambient IoT.

[0257] In an embodiment of the present application, the first-level first carrier carries simple fields and fewer information bits, such as: device activation or deactivation information, device identifier information, etc.; the second-level first carrier carries complex fields and more information bits, such as: uplink transmission time domain resource information, uplink transmission frequency domain resource information, device type information, reporting information type indication, backscatter air interface protocol type indication information, broadcast type information, uplink transmission modulation information, uplink transmission coding information, priority information, etc.

[0258] In at least one embodiment of the present application, the method further includes:

[0259] receiving a signal backscattered by a first type device according to the first level first carrier;

[0260] and / or,

[0261] A signal backscattered by a second type device according to the first-level first carrier and the second-level first carrier is received, or an uplink response signal generated by a second type device according to the first-level first carrier and the second-level first carrier is received.

[0262] In the embodiment of the present application, the AIoT device can choose to process only the first-level first carrier, or process the first-level first carrier and the second-level first carrier at the same time according to its own capabilities. It is compatible with the first type of devices and the second type of devices, allowing the first type of devices with low complexity to complete basic operations, and allowing the second type of devices with high complexity to complete more operations, thereby improving the network's signal coverage of the AIoT device and increasing the number of connections of the AIoT device.

[0263] Due to the different hardware structures, capabilities, and complexities of Type 1 and Type 2 devices, there are differences in their ability to process downlink information sent by base stations or intermediate nodes. Type 1 devices may only be able to process simple downlink information, while Type 2 devices can process complex downlink information.

[0264] Therefore, the first type of device only needs to decode the fields in the first level first bearer.The second type of device can decode the fields in the first level first bearer and the second level first bearer at the same time.

[0265] After decoding the first-level first carrier, the first-type device directly reflects the signal without generating a signal. Figure 3 As shown, the devices with device identifiers 101 and 103 are first type devices and can only backscatter signals.

[0266] After decoding the first-level first bearer and the second-level first bearer, the second-type device can either reflect the signal or independently generate an uplink response signal. As shown in the figure below, the device with device identifier 102 is a second-type device and can independently generate and transmit an uplink response signal.

[0267] The embodiments of the present application allow different types of AIoT devices with different capabilities to choose to decode only the first-level first carrier, or to decode the first-level first carrier and the second-level first carrier at the same time according to their own capabilities, so that the first type of device can backscatter signals and the second type of device can send uplink response signals, thereby being compatible with the first type of device with simple functions but low cost and the second type of device with slightly stronger functions but slightly higher cost, thereby improving the applicability of AIoT devices for different application scenarios.

[0268] In at least one embodiment of the present application, the time domain resource position of the second-level first bearer is the same as the time domain resource position of the first-level first bearer;

[0269] and / or,

[0270] The frequency domain resource position of the second-level first bearer is the same as the frequency domain resource position of the first-level first bearer.

[0271] In one implementation, the first-level first bearer contains only the time-domain resource location information of the second-level first bearer. After decoding the first-level first bearer, the device can obtain this time-domain resource location information and then determine the time-domain resource location of the second-level first bearer. The frequency-domain resource location of the second-level first bearer is the same as that of the first-level first bearer.

[0272] In another implementation, the first-level first bearer includes the frequency domain resource location information of the second-level first bearer. After decoding the first-level first bearer, the device can obtain the frequency domain resource location information and then determine the frequency domain resource location of the second-level first bearer. The time domain resource location of the second-level first bearer is the same as that of the first-level first bearer.

[0273] In another implementation, the first-level first bearer includes the time-domain resource location information and frequency-domain resource location information of the second-level first bearer. After decoding the first-level first bearer, the device can obtain the time-domain resource location and frequency-domain resource location information, and then determine the time-domain resource location of the second-level first bearer.

[0274] like Figure 4 、 Figure 5 and Figure 6 As shown in the figure, it shows the time-frequency position diagram of the downlink query signal sent by the base station to the AIoT device. Each small square in the figure represents an OFDM (Orthogonal Frequency Division Multiplexing) symbol in the time domain and a subcarrier in the frequency domain. In the figure, there are 14 OFDM symbols in the time domain, representing a time slot, and 12 subcarriers in the frequency domain, representing an RB (Resource Block). The preamble sequence occupies the first symbol of the time slot, and the base station uses the preamble sequence to synchronize with the AIoT device.

[0275] as follows Figure 4 As shown, the first-level downlink query signal only contains the time domain resource location information for the second-level downlink query signal, i.e., there is a two-symbol gap between the first-level downlink query signal and the end symbol. After decoding the first-level downlink query signal, the device can obtain this time domain resource location information and further determine the time domain resource location of the second-level downlink query signal. The frequency domain resource location of the second-level downlink query signal is the same as that of the first-level downlink query signal.

[0276] as follows Figure 5 As shown, the first-level downlink query signal contains the frequency domain resource location information of the second-level downlink query signal, namely, the subcarrier interval between the first-level downlink query signal and the end subcarrier is one subcarrier. After decoding the first-level downlink query signal, the device can obtain this frequency domain resource location information and further determine the frequency domain resource location of the second-level downlink query signal. The time domain resource location of the second-level downlink query signal is the same as that of the first-level downlink query signal.

[0277] as follows Figure 6As shown in the figure, the first-level downlink query signal contains the time-domain resource location information and frequency-domain resource location information of the second-level downlink query signal. Specifically, the second-level downlink query signal starts at the seventh symbol in the time domain and occupies four OFDM symbols. In the frequency domain, it starts at the fourth subcarrier and occupies eight subcarriers. After decoding the first-level downlink query signal, the device can obtain the time-domain resource location and frequency-domain resource location information, and then determine the time-domain and frequency-domain resource location of the second-level downlink query signal.

[0278] By adopting the above-mentioned method of the first-level first carrier indicating the time-frequency resource position of the second-level first carrier, the base station can dynamically indicate the specific transmission time-frequency resource position of the second-level first carrier through the first-level first carrier, so that the device can dynamically obtain the time-frequency resource position of the second-level first carrier by decoding the first-level first carrier, so that the time-frequency resource position configuration of the second-level first carrier is more flexible and efficient.

[0279] At least one embodiment of the present application also provides a method for independently configuring the time-frequency resource locations of the first-level first bearer and the second-level first bearer.

[0280] The independently configuring the time domain resource locations of the first-level first bearer and the second-level first bearer includes:

[0281] The time domain resources occupied by the second-level first carrier and the time domain resources occupied by the first-level first carrier are consecutive transmission time intervals TTI, symbols, time slots or other time units;

[0282] or,

[0283] The time domain resources occupied by the second-level first carrier and the time domain resources occupied by the first-level first carrier are separated by a preset number of TTIs, symbols, time slots, or other time units;

[0284] or,

[0285] The time domain resources occupied by the second-level first bearer are the same as the time domain resources occupied by the first-level first bearer;

[0286] The preset TTI number, symbol number, time slot number or other time unit number is configured by a high-level parameter or determined according to pre-configuration information.

[0287] The independently configured frequency domain resource locations of the first-level first carrier and the second-level first carrier include:

[0288] The frequency domain resources occupied by the second-level first carrier and the frequency domain resources occupied by the first-level first carrier are consecutive subcarriers, resource blocks or other frequency domain resource units;

[0289] or,

[0290] The frequency domain resources occupied by the second-level first carrier and the frequency domain resources occupied by the first-level first carrier are separated by a preset number of subcarriers, resource blocks, or other frequency domain resource units;

[0291] or,

[0292] The frequency domain resources occupied by the second-level first carrier are the same as the frequency domain resources occupied by the first-level first carrier;

[0293] The preset number of subcarriers, resource blocks or other frequency domain resource units is configured by high-level parameters or determined according to pre-configuration information.

[0294] like Figure 7 、 Figure 8 as well as Figure 9 Figure 1 shows the time-frequency position diagram of the downlink query signal sent by the base station to the AIoT device. Each small square in the figure represents an OFDM symbol in the time domain and a subcarrier in the frequency domain. There are 14 OFDM symbols in the time domain, representing one time slot, and 12 subcarriers in the frequency domain, representing one resource block (RB). The preamble sequence occupies the first symbol of the time slot, and the base station uses this preamble sequence to synchronize with the AIoT device.

[0295] like Figure 7 As shown, the first-level downlink query signal and the second-level downlink query signal are concatenated in time and occupy continuous symbols or time slots for transmission. The first-level downlink query signal and the second-level downlink query signal occupy the same time domain resources for transmission.

[0296] like Figure 8 As shown, the first-level downlink query signal and the second-level downlink query signal occupy the same time domain resources for transmission. The first-level downlink query signal and the second-level downlink query signal are cascaded together in frequency and occupy continuous subcarriers for transmission.

[0297] like Figure 9 As shown, the first-level downlink query signal and the second-level downlink query signal are sent at intervals, and the number of symbols or time slots between the two downlink query signals is (pre-)configured via parameters. The first-level downlink query signal and the second-level downlink query signal are sent using different frequency domain resources, and the number of RBs or subcarriers between the two downlink query signals is (pre-)configured via parameters.

[0298] The embodiment of the present application adopts this method of independently configuring the time-frequency resource position of the first-level first carrier and the time-frequency resource position of the second-level first carrier, which allows the base station to semi-statically configure or pre-configure the specific transmission time-frequency resource position of the first-level first carrier and the second-level first carrier through high-layer signaling. In this way, the time-frequency resource position configuration of the first-level first carrier and the second-level first carrier is simpler and saves physical layer signaling overhead.

[0299] In at least one embodiment of the present application, the device activation or deactivation information may be understood as: information in which the first communication entity activates or deactivates the AIoT device;

[0304] The broadcast type information includes at least one of the following: unicast, multicast, and broadcast;

[0305] The priority information may be understood as the priority of the current information sending process indicated by the first communication entity;

[0306] The uplink transmission modulation information is used to indicate at least one of the following modulation modes: amplitude shift keying (ASK), phase shift keying (PSK), frequency shift keying (FSK), and on-off keying (OOK);

[0307] The uplink transmission coding information is used to indicate at least one of the following coding modes: Manchester code, Miller code, FM0 code, Repetition code, Simplex code, and Reed-Muller RM code.

[0308] Optionally, Manchester codes also include Manchester-1 code, Manchester-2 code, Manchester-4 code, Manchester-8 code, etc. Miller codes also include Miller-1 code, Miller-2 code, Miller-4 code, Miller-8 code, etc., which will not be described in detail here.

[0309] In an optional implementation of the present application, the method further includes:

[0310] The first communication entity repeatedly sends the first-level first bearer and / or the second-level first bearer.

[0311] For example, the first communication entity periodically sends the first-level first bearer and the second-level first bearer; for another example, the first communication entity aperiodically sends the first-level first bearer and / or the second-level first bearer multiple times.

[0312] In at least one optional embodiment of the present application,

[0313] The first-stage first carrier is the first-segment first carrier, or the first-part first carrier;

[0314] and / or,

[0315] The second-level first carrier is a second-section first carrier, or a second portion first carrier.

[0316] In summary, the embodiments of the present application adopt an information sending method of at least two-level first carriers. Different types of AIoT devices with different capabilities can choose to process only the first-level first carrier according to their own capabilities, or process the first-level first carrier and the second-level first carrier at the same time. It is compatible with first-type devices and second-type devices, and can allow low-complexity first-type devices to complete basic operations, and can also allow high-complexity second-type devices to complete more operations, thereby improving the network's signal coverage of AIoT devices and increasing the number of connections of AIoT devices.

[0317] like Figure 10 As shown, the embodiment of the present application also provides an information processing method, the method comprising:

[0318] Step 1001: a first-type device receives, demodulates, or decodes a first-level first bearer sent by a first communication entity; and / or a second-type device receives, demodulates, or decodes a first-level first bearer and a second-level first bearer sent by the first communication entity;

[0323] In one implementation, the devices mentioned in the embodiments of the present application are specifically referred to as AIoT devices; optionally, AIoT devices can be divided into the following two types:

[0324] Type 1 devices: Peak power consumption is approximately 1 μW, with energy storage capability and an initial sampling frequency offset (SFO) of up to 10 X ppm, the device has neither downlink (DL) nor uplink (UL) amplification capabilities. The device's UL transmission is backscattered on an externally provided carrier.

The device's UL transmission can be generated internally by the device or backscattered on an externally provided carrier.

[0326] In another implementation, the first communication entity includes a base station, a terminal, or an intermediate node, which is not specifically limited here.

[0331] In one implementation, the first type of device only needs to decode the fields in the first level downlink query signal. The second type of device can decode the fields in both the first level downlink query signal and the second level downlink query signal.

[0332] In another implementation, after decoding the first-level downlink query signal, the first-type device directly reflects the signal without generating a signal. After decoding the first-level downlink query signal and the second-level downlink query signal, the second-type device can either reflect the signal or independently generate an uplink response signal; this application does not make specific limitations.

[0337] In the embodiment of the present application, the AIoT device can choose to process only the first-level first carrier, or process the first-level first carrier and the second-level first carrier at the same time according to its own capabilities. It is compatible with the first type of devices and the second type of devices, allowing the first type of devices with low complexity to complete basic operations, and allowing the second type of devices with high complexity to complete more operations, thereby improving the network's signal coverage of the AIoT device and increasing the number of connections of the AIoT device.

[0338] Due to the different hardware structures, capabilities, and complexities of Type 1 and Type 2 devices, there are differences in their ability to process downlink information sent by base stations or intermediate nodes. Type 1 devices may only be able to process simple downlink information, while Type 2 devices can process complex downlink information.

[0339] Therefore, the first type of device only needs to decode the fields in the first level first bearer.The second type of device can decode the fields in the first level first bearer and the second level first bearer at the same time.

[0347] and / or,

[0348] The frequency domain resource position of the second-level first bearer is the same as the frequency domain resource position of the first-level first bearer.

[0349] In one implementation, the first-level first bearer contains only the time-domain resource location information of the second-level first bearer. After decoding the first-level first bearer, the device can obtain this time-domain resource location information and then determine the time-domain resource location of the second-level first bearer. The frequency-domain resource location of the second-level first bearer is the same as that of the first-level first bearer.

[0350] In another implementation, the first-level first bearer includes the frequency domain resource location information of the second-level first bearer.

[0351] In another implementation, the first-level first bearer includes the time-domain resource location information and frequency-domain resource location information of the second-level first bearer. After decoding the first-level first bearer, the device can obtain the time-domain resource location and frequency-domain resource location information, and then determine the time-domain resource location of the second-level first bearer.

[0352] By adopting the above-mentioned method of the first-level first carrier indicating the time-frequency resource position of the second-level first carrier, the base station can dynamically indicate the specific transmission time-frequency resource position of the second-level first carrier through the first-level first carrier, so that the device can dynamically obtain the time-frequency resource position of the second-level first carrier by decoding the first-level first carrier, so that the time-frequency resource position configuration of the second-level first carrier is more flexible and efficient.

[0353] At least one embodiment of the present application also provides a method for independently configuring the time-frequency resource locations of the first-level first bearer and the second-level first bearer.

[0355] Based on the high-level parameter configuration or pre-configuration information, determine at least one of the following:

[0356] The time domain resources occupied by the second-level first carrier and the time domain resources occupied by the first-level first carrier are consecutive transmission time intervals TTI, symbols, time slots or other time units;

[0357] or,

[0358] The time domain resources occupied by the second-level first carrier and the time domain resources occupied by the first-level first carrier are separated by a preset number of TTIs, symbols, time slots, or other time units;

[0359] or,

[0360] The time domain resources occupied by the second-level first bearer are the same as the time domain resources occupied by the first-level first bearer;

[0361] The preset TTI number, symbol number, time slot number or other time unit number is configured by a high-level parameter or determined according to pre-configuration information.

[0369] The preset number of subcarriers, resource blocks or other frequency domain resource units is configured by high-level parameters or determined according to pre-configuration information.

[0370] The embodiment of the present application adopts this method of independently configuring the time-frequency resource position of the first-level first carrier and the time-frequency resource position of the second-level first carrier, which allows the base station to semi-statically configure or pre-configure the specific transmission time-frequency resource position of the first-level first carrier and the second-level first carrier through high-layer signaling. In this way, the time-frequency resource position configuration of the first-level first carrier and the second-level first carrier is simpler and saves physical layer signaling overhead.

[0381] In an optional implementation of the present application, the first-level first carrier is a first-segment first carrier, or a first-part first carrier;

[0382] and / or,

[0383] The second-level first carrier is a second-section first carrier, or a second portion first carrier.

[0384] In summary, the embodiments of the present application adopt an information sending method of at least two-level first carriers. Different types of AIoT devices with different capabilities can choose to process only the first-level first carrier according to their own capabilities, or process the first-level first carrier and the second-level first carrier at the same time. It is compatible with first-type devices and second-type devices, and can allow low-complexity first-type devices to complete basic operations, and can also allow high-complexity second-type devices to complete more operations, thereby improving the network's signal coverage of AIoT devices and increasing the number of connections of AIoT devices.

[0385] In order to more clearly describe the information sending method and information processing method provided in the embodiments of the present application, an example is provided below for illustration.

[0386] A base station, a terminal, or other node sends a first-level first bearer and a second-level first bearer to a device. The first-level first bearer and the second-level first bearer contain at least one of the following: device activation or deactivation information, uplink transmission time domain resource information, uplink transmission frequency domain resource information, uplink transmission resource reservation period information, carrier transmission time domain resource information, carrier transmission frequency domain resource information, carrier transmission resource reservation period information, device identifier information, source node identifier information of the first bearer, device type information, reporting information type indication, backscatter air interface protocol type indication information, broadcast type information, uplink transmission modulation information, uplink transmission coding information, and priority information. Optionally, the first-level first bearer also carries at least one of the following: time domain resource information of the second-level first bearer and frequency domain resource information of the second-level first bearer.

[0387] The device backscatters an incident signal or sends an uplink response signal according to the first downlink information.

[0388] Due to the different hardware structures, capabilities, and complexities of Type 1 and Type 2 devices, there are differences in their ability to process downlink information sent by base stations or intermediate nodes. Type 1 devices may only be able to process simple downlink information, while Type 2 devices can process complex downlink information.

[0389] For example, when the first bearer is a downlink query signal, the downlink query signal is divided into two levels: a first-level downlink query signal and a second-level downlink query signal.

[0390] The first-level downlink query signal carries simple fields and fewer information bits, such as device activation or deactivation information, device identifier information, etc.

[0391] The second-level downlink query signal carries complex fields and more information bits, such as: uplink transmission time domain resource information, uplink transmission frequency domain resource information, device type information, reporting information type indication, backscatter air interface protocol type indication information, broadcast type information, uplink transmission modulation information, uplink transmission coding information, priority information, etc.

[0392] In this way, different types of AIoT devices with different capabilities can choose to decode only the first-level downlink query signal, or decode the first-level and second-level downlink query signals at the same time according to their own capabilities, which is compatible with the first type of devices and the second type of devices. It can not only allow the first type of devices with low complexity to complete basic operations, but also allow the second type of devices with high complexity to complete more operations, such as: uplink transmission interference avoidance operations, modulation and coding method adjustment operations, etc., thereby improving the base station's signal coverage range for AIoT devices and increasing the number of connections of AIoT devices.

[0393] like Figure 11 As shown, after determining the downlink information, the base station first sends a first-level downlink query signal and then sends a second-level downlink query signal. For the first type of device that can only reflect external carriers, it only receives the first-level downlink query signal, obtains the device identifier information from it, and then backscatters the external incident signal. For the second type of device that can internally generate an uplink response signal, it receives the first-level downlink query signal and the second-level downlink query signal, and then obtains uplink transmission time domain resource information, uplink transmission frequency domain resource information, uplink transmission modulation information, uplink transmission coding information, and other information from them. It generates an uplink response signal according to the instructions of the information sent by the base station, and then sends the response signal to the base station.

[0394] By adopting the above-mentioned two-level downlink query signal sending method, different types of AIoT devices with different capabilities can choose to decode only the first-level downlink query signal, or decode the first-level and second-level downlink query signals at the same time according to their own capabilities. It is compatible with the first type of devices and the second type of devices, allowing the first type of devices with low complexity to complete basic operations, and the second type of devices with high complexity to complete more operations, thereby improving the signal coverage range of the base station to the AIoT devices and increasing the number of connections of AIoT devices.
