Description

Signal receiving and sending method, device and storage medium

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202311255738.8, filed on September 26, 2023, entitled “Signal Receiving and Transmitting Method, Device and Storage Medium,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of communication technologies, and in particular to a signal receiving and sending method, device, and storage medium. Background Art

[0004] The signal generation and transmission methods in New Radio (NR) systems require terminal devices to independently generate and transmit signals. Terminal devices also require a stable power supply to support complex signal processing processes such as modulation and coding, as well as the electromagnetic wave transmission of RF devices.

[0005] To address the labor and material costs associated with battery-powered IoT devices, which require regular recharging or replacement, the 3rd Generation Partnership Project (3GPP) has defined a new device type: the Ambient-Internet of Things (A-IoT). A-IoT devices draw energy from environmental sources such as wind, light, pressure, and wireless signals, offering low energy consumption and low cost.

[0006] However, some A-IoT devices have limited or no energy storage capacity, lack the ability to actively communicate, and lack sufficient energy storage to support autonomous signal generation and transmission. This means that the signal structure and signal transmission process in the NR system cannot be directly applied to the communication scenarios of A-IoT devices and cannot meet their communication needs.

A-IoT devices draw energy from environmental sources such as wind, light, pressure, and wireless signals, offering low energy consumption and low costs.

[0285] The signal generation and transmission methods in New Radio (NR) systems require NR terminals / user equipment (UE) to independently generate and transmit signals. Terminals must have a stable power supply to support complex signal processing processes such as modulation and coding, as well as the electromagnetic wave transmission of RF devices.

[0286] In the NR system, NR terminals transmit signals based on base station scheduling: the base station sends control information to the NR terminal, instructing it on which physical transmission resources to send signals; the NR terminal, based on the base station's instructions, generates signals according to the specified signal structure and transmits them on the specified time-frequency resources. The energy required for the NR terminal to generate and transmit RF signals comes from its own battery. Therefore, the transmitted and received signals are independent in terms of energy and usually have a certain time interval, thus meeting the processing time requirements of the complex received signal decoding and transmitted signal generation processes.

[0287] However, some A-IoT devices have limited or no energy storage capacity, lack the ability to actively communicate, and lack sufficient energy storage to support autonomous signal generation and transmission. This means that the signal structure and signal transmission process in the NR system cannot be directly applied to the communication scenarios of A-IoT devices and cannot meet their communication needs. Currently, NR systems lack communication technology for A-IoT devices.

[0288] Furthermore, in the NR transmission mechanism, the transmission of reference signals or signaling for synchronization, positioning, data scheduling, and initial access is independent of each other. A-IoT device applications typically have a high device connection density. Using existing mechanisms would result in transmission delays.

[0289] Different A-IoT device types have different energy storage and signal transmission capabilities. Designing independent signal transmission methods for each of the three types of devices would result in latency and transmission resource overhead.

[0290] In response to the above-mentioned problems existing in the related technologies, the embodiments of the present disclosure provide a signal receiving and sending method, device and storage medium, which triggers the first device to communicate with the second device and / or triggers the first device to perform a first operation through a first signal sent by a second device carrying information corresponding to a first device of at least one device type. This fully considers the characteristics of devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices in terms of energy storage and signal transmission, and implements a communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, filling the gap in communication technology for A-IoT devices in the current NR system, while minimizing the complexity of signaling design and the resource overhead and latency of signaling transmission.

[0291] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist.

[0298] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0299] FIG1 is a flow chart of a signal receiving method provided in an embodiment of the present disclosure. As shown in FIG1 , the method is performed by a first device, which is a terminal device, such as an NR terminal, an A-IoT device, etc. The present disclosure is mainly described with reference to the A-IoT device. The method includes at least the following steps:

[0300] Step 101: Receive a first signal sent by a second device, where the first signal is used to trigger the first device to communicate with the second device and / or the first signal is used to trigger the first device to perform a first operation;

[0301] The first signal carries information corresponding to a first device of at least one device type.

[0302] Specifically, the second device may be a network device, such as a base station, an integrated access backhaul (IAB) node, a relay node, an auxiliary node, an intermediate node, etc., or may be a user equipment.

[0303] The first device receives a first signal sent by the second device, where the first signal may be a query signal. The first signal may indicate one or more first devices, and the indicated first devices may belong to one or more device types.

[0304] The first signal carries one or more pieces of information, each of which corresponds to a first device of at least one device type. In the disclosed embodiments, device type primarily refers to different types of A-IoT devices, which can be distinguished based on their storage capacity and ability to independently generate signals.

[0305] Optionally, the first signal only carries one or more pieces of information corresponding to A-IoT devices of the same type. Optionally, the first signal also carries one or more pieces of information corresponding to A-IoT devices of different types.

[0306] Optionally, the first signal is used to trigger communication between the first device and the second device, that is, after receiving the first signal, the first device communicates with the second device and sends a signal to the second device, such as data transmission and reception, initial access, mobility management, positioning and other scenarios.

[0307] Optionally, the first signal is used to trigger the first device to perform a first operation, such as synchronization, energy collection, and other scenarios. In this case, the first device does not need to send a signal to the second device.

[0308] Optionally, the first signal is used to trigger the first device to communicate with the second device, and is also used to trigger the first device to perform the first operation.

[0309] The signal receiving method provided by the embodiment of the present disclosure triggers the first device to communicate with the second device and / or triggers the first device to perform a first operation through a first signal sent by a second device that carries information corresponding to a first device of at least one device type. This method fully considers the characteristics of devices with limited storage capacity and independent signal generation capacity, such as A-IoT devices, in terms of energy storage and signal transmission, and implements a communication solution for devices with limited storage capacity and independent signal generation capacity, such as A-IoT devices.

[0310] In some embodiments, the at least one device type includes:

[0311] Environmental IoT A-IoT device type A;

[0312] A-IoT device type B;

[0313] A-IoT device type C.

[0314] Specifically, in 3GPP, A-IoT devices are divided into the following three types based on whether they have energy storage capabilities and the ability to independently generate signals:

[0315] ①A-IoT device type A: No energy storage capability, no ability to independently generate signals, and transmits signals via backscattering.

[0316] ②A-IoT device type B: has energy storage capabilities, but no independent signal generation capabilities, and transmits signals through backscattering.

[0317] ③A-IoT device type C: has energy storage capabilities, the ability to independently generate signals, and uses radio frequency devices for signal transmission.

[0318] The embodiments of the present disclosure mainly involve distinguishing the types of different A-IoT devices. Optionally, the multiple first devices indicated by the first signal may also include NR devices. The present disclosure does not exclude the scenario of collaborative communication between NR devices and A-IoT devices. It should be further noted that the device types of A-IoT can also be classified into other categories according to actual needs.

[0319] The signal receiving method provided in the embodiment of the present disclosure classifies first devices according to their energy storage capacity and independent signal generation capacity, supports communication with first devices of different device types, further improves the communication solution for devices with limited storage capacity and independent signal generation capacity, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0320] In some embodiments, the signal receiving method further includes:

[0321] Determine at least one of the following through predefined or preconfigured means:

[0322] a signal waveform corresponding to the information carried in the first signal;

[0323] the manner in which a signal corresponding to the information carried in the first signal constitutes the first signal;

[0324] the order of information carried in the first signal;

[0325] time domain resources occupied by the information carried in the first signal;

[0326] The frequency domain resources occupied by the information carried in the first signal.

[0327] Specifically, the first device may determine the relevant information of the first signal by means of protocol pre-definition or network device pre-configuration (e.g., second device pre-configuration). The specific content may include at least one of the following:

[0328] ① The signal waveform corresponding to the information carried in the first signal. Different signal waveforms depend on different modulation methods, which may be amplitude shift keying (ASK), frequency shift keying (FSK), orthogonal frequency division multiplexing (OFDM), etc. Optionally, the signal waveforms corresponding to different information carried in the first signal are the same. Optionally, the signal waveforms corresponding to different information carried in the first signal are different. Optionally, the signal waveforms corresponding to information corresponding to different device types are the same. Optionally, the signal waveforms corresponding to information corresponding to different device types are different.

[0329] ② The manner in which signals corresponding to the information carried in the first signal constitute the first signal. The manner in which signals corresponding to different information constitute the first signal may be time division multiplexing, frequency division multiplexing, code division multiplexing, etc.

[0330] ③ The order of the information carried in the first signal. This order can be generated randomly based on different information, or it can be generated based on certain rules. For example, it can be generated based on the priority of scheduling or business needs.

[0331] ④ The time domain resources occupied by the information carried in the first signal. Furthermore, the time domain resources occupied by information corresponding to different device types may be the same or different. Therefore, the time domain resources occupied by information corresponding to first devices of different device types in the first signal can be further informed to the first device through protocol pre-definition or pre-configuration.

[0332] ⑤ The frequency domain resources occupied by the information carried in the first signal. Furthermore, the frequency domain resources occupied by information corresponding to different device types may be the same or different. Therefore, the frequency domain resources occupied by information corresponding to first devices of different device types in the first signal may be further informed to the first device through protocol pre-definition or pre-configuration.

[0333] Among them, the pre-configuration method can be a system message, radio resource control (RRC) message, medium access control control element (MAC CE), downlink control indication (DCI) and other messages sent by the second device, carrying the above-mentioned relevant content of the first signal.

[0334] The signal receiving method provided in the embodiments of the present disclosure informs the first device of relevant information of the first signal in a predefined or preconfigured manner, such as the signal waveform corresponding to each information carried by the first signal, the occupied time-frequency resources, the order of constituting the first signal, the method of constituting the first signal, etc., so that different numbers and types of first devices can all receive the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0335] In some embodiments, when the first signal is used to trigger communication between the first device and the second device, the method further includes:

[0336] Based on the first signal, a response signal is sent to the second device, where the response signal includes response information of part or all of the information carried in the first signal.

[0337] Specifically, the first device receives a first signal sent by the second device. In some cases, it needs to provide feedback to the second device, that is, communicate with the second device, specifically including: based on the first signal sent by the second device, sending a response signal to the second device, and the response signal includes response information of part or all of the information carried in the first signal.

[0338] For example, the first signal may include reporting request information, which instructs the first device to report data or control information. For example, the first signal may include positioning information, instructing the first device to send and / or receive positioning signals. This type of information often requires the first device to provide feedback to the second device. Of course, the first device can independently choose whether to include the corresponding response information in the response signal.

[0339] For example, if the first signal carries reporting request information and synchronization information, the first device can carry the response information of the reporting request information in the response signal. For synchronization information, the first device does not need to feedback the response information to the second device and can complete synchronization based on the timing information of the second device. For example, if the first signal carries energy collection information and positioning information, the first device can carry the response information of the positioning information in the response signal. For energy collection information, the first device can collect the energy of the first signal for subsequent signal processing and transmission without feedback of response information to the second device.

[0340] For another example, the first signal carries reporting request information, synchronization information, and positioning information, but since the first device has no positioning requirements, the response signal only carries response information to the reporting request information.

[0341] The signal receiving method provided by the embodiment of the present disclosure is that when the first device receives the first signal sent by the second device for triggering communication between the first device and the second device, the first device feeds back a response signal to the second device, wherein the response signal includes response information of part or all of the information carried in the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices.

[0342] In some embodiments, the sending a response signal to the second device includes:

[0343] The response signal is sent to the second device by at least one of backscattering, uplink transmission and sidelink transmission.

[0344] Specifically, a backscatter communication system typically consists of a reader with RF capabilities and a tag without RF capabilities. The reader sends a radio frequency signal to the tag. The electromagnetic wave of the RF signal reflects off the tag's antenna surface, forming an echo known as the backscatter signal. By varying the antenna's impedance, the tag modulates information into the backscatter signal. The reader receives and reads the backscatter signal from the tag, thereby obtaining the information transmitted by the tag.

[0345] Some A-IoT devices lack the ability to actively communicate and can only backscatter received signals, carrying information in the backscattered signals. In A-IoT communication scenarios, the tag is the A-IoT device, and the reader can be a base station, NR terminal, etc.

[0346] For a first device capable of independently generating a signal, a response signal is sent to the second device via at least one of backscatter, uplink transmission, and sidelink transmission. The response signal is a backscatter signal, an uplink signal, or a sidelink transmission signal. For a first device that does not have the ability to independently generate a signal, a response signal is sent to the second device via backscatter. The response signal is a backscatter signal.

[0347] The signal receiving method provided in the embodiment of the present disclosure is based on whether the first device has the ability to independently generate signals, and thus feeds back a response signal to the second device through at least one of backscattering, uplink transmission and side transmission, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices.

[0348] In some embodiments, the first signal carries at least one of the following information:

[0349] First indication information used to instruct the first device to start an initial access process;

[0350] second indication information used to instruct the first device to receive and / or send a positioning signal;

[0351] third indication information used to instruct the first device to report information;

[0352] information for authenticating the first device;

[0353] Information for verifying the security and integrity of data stored on the first device;

[0354] Activate information about the first device.

[0355] Specifically, in a scenario where a first device communicates with a second device, the first signal carries one or more pieces of information.

[0356] This information often has an indicative function. For example, first indication information used to instruct the first device to initiate the initial access process can be referred to as initial access information. For example, second indication information used to instruct the first device to receive and / or transmit positioning signals can be referred to as positioning information. For example, indication information used to instruct the first device to report information, including reporting data and control information, can be referred to as reporting request information.

[0357] For another example, information used to authenticate the identity of the first device can be referred to as authentication information. For example, information used to verify the security and integrity of data stored on the first device can be referred to as integrity verification information. For example, information used to activate the first device can be used to wake the first device from an inactive state or a state with low power consumption to begin transmitting and receiving data.

[0358] Optionally, the first signal also carries at least one of the following: identification (ID) information of the first device; and group identification information of the group to which the first device belongs. The first signal carries the identification information of the first device, or the target device, which may be an ID number, indicating that the first device corresponding to the identification information needs to receive and / or respond to the first signal. The first signal carries group identification information indicating that all first devices within the identified group need to receive and / or respond to the first signal.

[0359] The signal receiving method provided by the embodiments of the present disclosure, in a scenario where a first device and a second device need to communicate, carries information related to various mechanisms such as data transmission, initial access, mobility management, and positioning in the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0360] In some embodiments, the sending a response signal to the second device includes:

[0361] sending the response signal on continuous time domain resources and continuous frequency domain resources; or,

[0362] Sending the response signal on continuous time domain resources and discontinuous frequency domain resources; or,

[0363] Sending the response signal on discontinuous time domain resources and continuous frequency domain resources; or,

[0364] The response signal is sent on discontinuous time domain resources and discontinuous frequency domain resources.

[0365] Specifically, the first device sends a response signal to the second device, and the transmission resources used by the response signal may be continuous or discontinuous in the frequency domain or time domain.

[0366] When using continuous time domain resources, one or more information contained in the response signal can be transmitted in the time domain in different orders. Figure 2 is a schematic diagram of a time-domain continuous response signal provided by an embodiment of the present disclosure. As shown in Figure 2, the response signal contains three different response information: response 1, response 2, and response 3, and the transmission order is {1, 2, 3}, which are transmitted on continuous time domain resources. The transmission order can also be {1, 3, 2}, {2, 1, 3}, {2, 3, 1}, {3, 1, 2}, {3, 2, 1}, etc.

[0367] When using discontinuous time domain resources, one or more information contained in the response signal can be transmitted in the time domain in different orders and combinations. Figure 3 is a schematic diagram of a discontinuous time domain response signal provided by an embodiment of the present disclosure. As shown in Figure 3, the response signal contains two different response information: response 1, response 2, and response 3. The three response information are divided into two sub-segments for transmission in the time domain. The two sub-segments respectively contain one response information {1} and two response information {2, 3}.

[0368] When using continuous frequency domain resources, one or more information contained in the response signal can be transmitted in different orders in the frequency domain. Figure 4 is a schematic diagram of a continuous frequency domain response signal provided by an embodiment of the present disclosure. As shown in Figure 4, the response signal contains two different response information: response 1 and response 2, with the information order {1, 2}, and is transmitted on continuous frequency domain resources. The information order can also be {2, 1}.

[0369] When using discontinuous frequency domain resources, one or more information contained in the response signal can be transmitted in the frequency domain in different orders and combinations. Figure 5 is a schematic diagram of a discontinuous time domain response signal provided by an embodiment of the present disclosure. As shown in Figure 5, the response signal contains three different response information: response 1 and response 2. The two response information are divided into two sub-segments for transmission in the time domain. The two sub-segments respectively contain one response information {1} and one response information {2}.

[0370] The signal receiving method provided by the embodiment of the present disclosure supports the first device to feedback a response signal on continuous / discontinuous time domain / frequency domain resources in a communication scenario with a second device, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while providing a certain degree of flexibility for the scheduling of transmission resources.

[0371] In addition to scenarios where a first device communicates with a second device and feeds back a response signal to the second device, another scenario is where, after receiving a first signal, the first device performs a first operation based on the information carried in the first signal without providing any feedback to the second device. This is typically the case in synchronization or energy storage scenarios. In actual implementation, the first signal may often carry multiple types of information, including both information that requires feedback from the first device and information that does not.

[0372] In some embodiments, the first operation includes:

[0373] Synchronize with the second device based on the timing information of the second device carried in the first signal and / or fourth indication information used to instruct the first device to obtain the timing information.

[0374] Specifically, for synchronization scenarios, the first signal carries at least the timing information of the second device and / or fourth indication information for instructing the first device to obtain the timing information of the first device. The first device synchronizes with the second device based on this information carried in the first signal. Synchronization in the disclosed embodiments can be either fine synchronization or coarse synchronization.

[0375] In some embodiments, the first operation includes:

[0376] The energy of the first signal is acquired based on the fifth indication information carried in the first signal and used to indicate the energy of the first signal and / or the sixth indication information used to instruct the first device to acquire the energy of the first signal.

[0377] Specifically, for the energy storage scenario, the first signal carries at least fifth indication information indicating the energy of the first signal and / or sixth indication information instructing the first device to obtain energy from the first signal. Based on the fifth indication information and / or the sixth indication information, the first device obtains energy from the first signal.

[0378] The first signal is a radio frequency signal. If the first device has energy storage capability, the energy of the radio frequency signal can be obtained and used for subsequent signal transmission and reception.

[0379] Optionally, regardless of whether the first device needs to provide feedback of the first signal to the second device or does not need to provide feedback of the first signal, the first signal may also carry at least one of the following information: identification information of the first device; and group identification information of the group to which the first device belongs. The first signal carries the identification information of the first device, or the identification information of the target device. The identification information may be an ID number, indicating that the first device corresponding to the identification information needs to receive and / or respond to the first signal. The first signal carries the group identification information, indicating that all first devices within the identified group need to receive and / or respond to the first signal.

[0380] The signal receiving method provided by the embodiment of the present disclosure supports the case where the first signal carries information that does not require feedback from the first device, and the first device independently instructs the corresponding operation based on the information carried in the first signal. This further improves the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices in scenarios such as synchronization and energy storage.

[0381] In some embodiments, receiving the first signal sent by the second device includes:

[0382] The first signal is received, which is sent by the second device in the form of a bit stream.

[0383] Specifically, the first signal may be in the form of a bit stream, and different bit fields correspond to different information, which together constitute a sequence of information carried in the first signal.

[0384] In some embodiments, receiving the first signal sent by the second device includes:

[0385] receiving the first signal on continuous time domain resources and continuous frequency domain resources; or,

[0386] receiving the first signal on continuous time domain resources and discontinuous frequency domain resources; or,

[0387] receiving the first signal on discontinuous time domain resources and continuous frequency domain resources; or,

[0388] The first signal is received on discontinuous time domain resources and discontinuous frequency domain resources.

[0389] Specifically, the first device receives a first signal sent by the second device, and the transmission resources used by the first signal may be continuous / discontinuous in the frequency domain / time domain.

[0390] When using continuous time domain resources, one or more information contained in the first signal can be transmitted in the time domain in different orders. Figure 6 is a schematic diagram of a first signal with a continuous time domain according to an embodiment of the present disclosure. As shown in Figure 6, the first signal contains four different information: information 1, information 2, information 3, and information 4, which are transmitted in the order of {1, 2, 3, 4} and transmitted on continuous time domain resources. The transmission order of the four information can be changed.

[0391] When discontinuous time domain resources are used, one or more information contained in the first signal can be transmitted in the time domain in different orders and combinations. Figure 7 is a schematic diagram of a first signal with discontinuous time domain provided by an embodiment of the present disclosure. As shown in Figure 7, the first signal contains four different information: information 1, information 2, information 3, and information 4. The four information are divided into two sub-segments for transmission in the time domain. The two sub-segments contain one information {1} and three information {2, 3, 4}, respectively. Optionally, the transmission order of the two sub-segments can be changed, and the transmission order of the multiple information contained in one sub-segment can also be changed.

[0392] When using continuous frequency domain resources, one or more information contained in the first signal can be transmitted in a different order in the frequency domain. Figure 8 is a schematic diagram of a first signal with a continuous frequency domain provided by an embodiment of the present disclosure. As shown in Figure 8, the first signal contains three different information: information 1, information 2, and information 3, which are transmitted in the order of {1, 2, 3} on continuous frequency domain resources. The transmission order of the three information can be changed.

[0393] When using discontinuous frequency domain resources, one or more information contained in the first signal can be transmitted in the frequency domain in different orders and combinations. Figure 9 is a schematic diagram of a discontinuous first signal in the frequency domain provided by an embodiment of the present disclosure. As shown in Figure 9, the first signal contains three different information: information 1, information 2, and information 3. The three information are divided into three subsegments in the time domain for transmission, and each of the three subsegments contains one information. The transmission order of the three subsegments can be changed.

[0394] The signal receiving method provided by the embodiment of the present disclosure supports the first device to receive signals on continuous / discontinuous time domain / frequency domain resources, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while providing a certain degree of flexibility for the scheduling of transmission resources.

[0395] FIG10 is a flow chart of a signal transmission method provided by an embodiment of the present disclosure. As shown in FIG10 , the method is performed by a second device, which can be a network device such as a base station, an integrated access backhaul (IAB) node, a relay node, an auxiliary node, an intermediate node, etc., or a user device. The method includes at least the following steps:

[0396] Step 1001: Send a first signal to a first device, where the first signal is used to trigger the first device to communicate with the second device and / or the first signal is used to trigger the first device to perform a first operation;

[0397] The first signal carries information corresponding to a first device of at least one device type.

[0398] Specifically, the first device is a terminal device, such as an NR terminal, an A-ToT device, etc. The embodiments of this disclosure are mainly described for A-IoT devices.

[0399] The second device sends a first signal to the first device, where the first signal may be a query signal. The first signal may indicate one or more first devices, and the indicated first devices may belong to one or more device types.

[0400] The first signal carries one or more pieces of information, each of which corresponds to a first device of at least one device type. In the disclosed embodiments, device types primarily refer to different types of A-IoT devices. A-IoT devices can be distinguished based on their storage capacity and ability to independently generate signals.

[0401] Optionally, the first signal only carries one or more pieces of information corresponding to A-IoT devices of the same type. Optionally, the first signal also carries one or more pieces of information corresponding to A-IoT devices of different types.

[0402] Optionally, the first signal is used to trigger communication between the first device and the second device, that is, after receiving the first signal, the first device communicates with the second device and sends a signal to the second device, such as data transmission and reception, initial access, mobility management, positioning and other scenarios.

[0403] Optionally, the first signal is used to trigger the first device to perform a first operation, such as synchronization, energy collection, and other scenarios. In this case, the first device does not need to send a signal to the second device.

[0404] Optionally, the first signal is used to trigger the first device to communicate with the second device, and is also used to trigger the first device to perform the first operation.

[0405] The signal sending method provided by the embodiment of the present disclosure triggers the first device to communicate with the second device and / or triggers the first device to perform a first operation through a first signal sent by a second device that carries information corresponding to a first device of at least one device type. This method fully considers the characteristics of devices with limited storage capacity and independent signal generation capacity, such as A-IoT devices, in terms of energy storage and signal transmission, and implements a communication solution for devices with limited storage capacity and independent signal generation capacity, such as A-IoT devices.

[0406] In some embodiments, the at least one device type includes:

[0407] Environmental IoT A-IoT device type A;

[0408] A-IoT device type B;

[0409] A-IoT device type C.

[0410] Specifically, in 3GPP, A-IoT devices are divided into the following three types based on whether they have energy storage capabilities and the ability to independently generate signals:

[0411] ①A-IoT device type A: No energy storage capability, no ability to independently generate signals, and transmits signals via backscattering.

[0412] ②A-IoT device type B: has energy storage capabilities, but no independent signal generation capabilities, and transmits signals through backscattering.

[0413] ③A-IoT device type C: has energy storage capabilities, the ability to independently generate signals, and uses radio frequency devices for signal transmission.

[0414] The embodiments of the present disclosure mainly involve distinguishing the types of different A-IoT devices. Optionally, the multiple first devices indicated by the first signal may also include NR devices. The present disclosure does not exclude the scenario of collaborative communication between NR devices and A-IoT devices. It should be further noted that the device types of A-IoT can also be classified into other categories according to actual needs.

[0415] The signal sending method provided in the embodiment of the present disclosure classifies the first device according to its energy storage capacity and independent signal generation capability, supports communication with first devices of different device types, and further improves the communication solution for devices with limited storage capacity and independent signal generation capability, such as A-IoT devices.

[0416] In some embodiments, the method further comprises:

[0417] Instructing the first device, in a preconfigured manner, at least one of the following:

[0418] a signal waveform corresponding to the information carried in the first signal;

[0419] the manner in which a signal corresponding to the information carried in the first signal constitutes the first signal;

[0420] the order of information carried in the first signal;

[0421] time domain resources occupied by the information carried in the first signal;

[0422] The frequency domain resources occupied by the information carried in the first signal.

[0423] Specifically, the second device may indicate information related to the first signal to the first device in a preconfigured manner. The specific content may include at least one of the following:

[0424] ① The signal waveform corresponding to the information carried in the first signal. Different signal waveforms depend on different modulation schemes, such as ASK, FSK, and OFDM. Optionally, the signal waveforms corresponding to different information carried in the first signal are the same. Optionally, the signal waveforms corresponding to different information carried in the first signal are different. Optionally, the signal waveforms corresponding to information corresponding to different device types are the same. Optionally, the signal waveforms corresponding to information corresponding to different device types are different.

[0425] ② The manner in which signals corresponding to the information carried in the first signal constitute the first signal. The manner in which signals corresponding to different information constitute the first signal may be time division multiplexing, frequency division multiplexing, code division multiplexing, etc.

[0426] ③ The order of the information carried in the first signal. This order can be generated randomly based on different information, or it can be generated based on certain rules. For example, it can be generated based on the priority of scheduling or business needs.

[0427] ④ The time domain resources occupied by the information carried in the first signal. Furthermore, the time domain resources occupied by information corresponding to different device types may be the same or different. Therefore, the time domain resources occupied by information corresponding to first devices of different device types in the first signal can be further informed to the first device through protocol pre-definition or pre-configuration.

[0428] ⑤ The frequency domain resources occupied by the information carried in the first signal. Furthermore, the frequency domain resources occupied by information corresponding to different device types may be the same or different. Therefore, the frequency domain resources occupied by information corresponding to first devices of different device types in the first signal may be further informed to the first device through protocol pre-definition or pre-configuration.

[0429] Among them, the pre-configuration method can be to carry the above-mentioned relevant content of the first signal in a system message, RRC message, MAC CE, DCI and other messages sent to the first device.

[0430] The signal sending method provided in the embodiments of the present disclosure informs the first device of relevant information of the first signal in a pre-configured manner, such as the signal waveform corresponding to each information carried by the first signal, the occupied time-frequency resources, the order of constituting the first signal, the method of constituting the first signal, etc., so that different numbers and types of first devices can receive the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0431] In some embodiments, when the first signal is used to trigger communication between the first device and the second device, the method further includes:

[0432] A response signal is received, which is sent by the first device based on the first signal, where the response signal includes response information of part or all of the information carried in the first signal.

[0433] Specifically, the second device sends a first signal to the first device. In some cases, the first device needs to provide feedback, that is, communicate with the second device, which specifically includes: receiving a response signal sent by the first device based on the first signal, and the response signal includes response information of part or all of the information carried in the first signal.

[0434] For example, the first signal may include reporting request information, which instructs the first device to report data or control information. For example, the first signal may include positioning information, instructing the first device to send and / or receive positioning signals. This type of information often requires the first device to provide feedback to the second device. Of course, the first device can independently choose whether to include the corresponding response information in the response signal.

[0435] For example, if the first signal carries reporting request information and synchronization information, the response signal may carry response information for the reporting request information. However, for synchronization information, the first device can complete synchronization based on the timing information of the second device without feeding back the response information to the second device. For example, if the first signal carries energy collection information and positioning information, the response signal may carry response information for the positioning information. However, for energy collection information, the first device can collect the energy of the first signal for subsequent signal processing and transmission without feeding back the response information to the second device.

[0436] For another example, the first signal carries reporting request information, synchronization information, and positioning information, but since the first device has no positioning requirements, the response signal may only carry response information to the reporting request information.

[0437] The signal sending method provided by the embodiment of the present disclosure, in which a second device receives a response signal sent by a first device based on the first signal, wherein the response signal includes response information of part or all of the information carried in the first signal. This further improves the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0438] In some embodiments, receiving a response signal sent by the first device based on the first signal includes:

[0439] Receive the response signal sent by the first device through at least one of backscattering, uplink transmission and sidelink transmission.

[0440] Specifically, a backscatter communication system typically consists of a reader with RF capabilities and a tag without RF capabilities. The reader sends a radio frequency signal to the tag. The electromagnetic wave of the RF signal reflects off the tag's antenna surface, forming an echo known as the backscatter signal. By varying the antenna's impedance, the tag modulates information into the backscatter signal. The reader receives and reads the backscatter signal from the tag, thereby obtaining the information transmitted by the tag.

[0441] Some A-IoT devices lack the ability to actively communicate and can only backscatter received signals, carrying information in the backscattered signals. In A-IoT communication scenarios, the tag is the A-IoT device, and the reader can be a base station, NR terminal, etc.

[0442] For a first device capable of independently generating signals, the response signal received by the second device is sent via at least one of backscatter, uplink transmission, and sidelink transmission, and the response signal is a backscatter signal, an uplink signal, or a sidelink transmission signal. For a first device that does not have the capability of independently generating signals, the response signal received by the second device is sent via backscatter, and the response signal is a backscatter signal.

[0443] The signal sending method provided in the embodiment of the present disclosure is based on whether the first device has the ability to independently generate signals, and thus feeds back a response signal to the second device through at least one of backscattering, uplink transmission and side transmission. This further improves the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0444] In some embodiments, the first signal carries at least one of the following information:

[0445] First indication information used to instruct the first device to start an initial access process;

[0446] second indication information used to instruct the first device to receive and / or send a positioning signal;

[0447] third indication information used to instruct the first device to report information;

[0448] information for authenticating the first device;

[0449] Information for verifying the security and integrity of data stored on the first device;

[0450] Activate information about the first device.

[0451] Specifically, in a scenario where a first device communicates with a second device, the first signal carries one or more pieces of information.

[0452] This information often has an indicative function. For example, first indication information used to instruct the first device to initiate the initial access process can be referred to as initial access information. For example, second indication information used to instruct the first device to receive and / or transmit positioning signals can be referred to as positioning information. For example, indication information used to instruct the first device to report information, including reporting data and control information, can be referred to as reporting request information.

[0453] For another example, information used to authenticate the identity of the first device can be referred to as authentication information. For example, information used to verify the security and integrity of data stored on the first device can be referred to as integrity verification information. For example, information used to activate the first device can be used to wake the first device from an inactive state or a state with low power consumption to begin transmitting and receiving data.

[0454] Optionally, the first signal also carries at least one of the following: identification (ID) information of the first device; and group identification information of the group to which the first device belongs. The first signal carries the identification information of the first device, or the target device, which may be an ID number, indicating that the first device corresponding to the identification information needs to receive and / or respond to the first signal. The first signal carries group identification information indicating that all first devices within the identified group need to receive and / or respond to the first signal.

[0455] Optionally, the first signal may be sent to the first device periodically or aperiodically, depending on the requirements of the second device.

[0456] Optionally, the first signal may be sent to the first device via unicast or broadcast, depending on the requirements of the second device.

[0457] The signal receiving method provided by the embodiments of the present disclosure, in a scenario where a first device and a second device need to communicate, carries information related to various mechanisms such as data transmission, initial access, mobility management, and positioning in the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities, such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0458] In some embodiments, receiving a response signal sent by the first device based on the first signal includes:

[0459] receiving the response signal on continuous time domain resources and continuous frequency domain resources; or,

[0460] receiving the response signal on continuous time domain resources and discontinuous frequency domain resources; or,

[0461] receiving the response signal on discontinuous time domain resources and continuous frequency domain resources; or,

[0462] The response signal is received on discontinuous time domain resources and discontinuous frequency domain resources.

[0463] Specifically, the second device receives the response signal sent by the first device, and the transmission resources used by the response signal may be continuous / discontinuous in the frequency domain / time domain.

[0464] When continuous time domain resources are used, one or more information contained in the response signal can be transmitted in the time domain in different orders.

[0465] When discontinuous time domain resources are used, one or more information contained in the response signal can be transmitted in the time domain in different orders and combinations.

[0466] When continuous frequency domain resources are used, one or more information contained in the response signal can be transmitted in the frequency domain in different orders.

[0467] When discontinuous frequency domain resources are used, one or more information contained in the response signal can be transmitted in the frequency domain in different orders and combinations.

[0468] In a scenario where transmission resources are discontinuous, the multiple response information contained in the response signal can be divided into different sub-segments. A sub-segment contains one or more response information. The transmission order of different sub-segments can be changed, and the transmission order of different response information in a sub-segment can also be changed.

[0469] The signal receiving method provided by the embodiment of the present disclosure supports the first device to feedback a response signal on continuous / discontinuous time domain / frequency domain resources in a communication scenario with the second device, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while reducing signaling transmission delay and providing a certain degree of flexibility for the scheduling of transmission resources.

[0470] In addition to scenarios where a first device communicates with a second device and feeds back a response signal to the second device, another scenario is where, after receiving a first signal, the first device performs a first operation based on the information carried in the first signal without providing any feedback to the second device. This is typically the case in synchronization or energy storage scenarios. In actual implementation, the first signal may often carry multiple types of information, including both information that requires feedback from the first device and information that does not.

[0471] In some embodiments, the first signal carries timing information of the second device and / or fourth indication information for instructing the first device to obtain the timing information, and the first operation includes synchronization with the second device.

[0472] Specifically, for synchronization scenarios, the first signal carries at least the timing information of the second device and / or fourth indication information for instructing the first device to obtain the timing information of the first device. This allows the first device to synchronize with the second device based on this information carried in the first signal. Synchronization in the disclosed embodiments can be either fine or coarse synchronization.

[0473] In some embodiments, the first signal carries fifth indication information for indicating the energy of the first signal and / or sixth indication information for instructing the first device to obtain the energy of the first signal, and the first operation includes obtaining the energy of the first signal.

[0474] Specifically, for the energy storage scenario, the first signal carries at least fifth indication information indicating the energy level of the first signal and / or sixth indication information instructing the first device to obtain energy from the first signal. This allows the first device to obtain energy from the first signal based on the fifth indication information and / or the sixth indication information.

[0475] The first signal is a radio frequency signal. If the first device has energy storage capability, the energy of the radio frequency signal can be obtained and used for subsequent signal transmission and reception.

[0476] Optionally, regardless of whether the first device needs to provide feedback of the first signal to the second device or does not need to provide feedback of the first signal, the first signal may also carry at least one of the following information: identification information of the first device; and group identification information of the group to which the first device belongs. The first signal carries the identification information of the first device, or the identification information of the target device. The identification information may be an ID number, indicating that the first device corresponding to the identification information needs to receive and / or respond to the first signal. The first signal carries the group identification information, indicating that all first devices within the identified group need to receive and / or respond to the first signal.

[0477] The signal sending method provided in the embodiment of the present disclosure supports the situation where the first signal carries information that does not require feedback from the first device, and the first device independently indicates the corresponding operation based on the information carried in the first signal. This further improves the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices in scenarios such as synchronization and energy storage, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0478] In some embodiments, sending the first signal to the first device includes:

[0479] The first signal is sent to the first device in the form of a bit stream.

[0480] Specifically, the first signal may be in the form of a bit stream, and different bit fields correspond to different information, which together constitute a sequence of information carried in the first signal.

[0481] In some embodiments, sending the first signal to the first device includes:

[0482] sending the first signal on continuous time domain resources and continuous frequency domain resources; or,

[0483] sending the first signal on continuous time domain resources and discontinuous frequency domain resources; or,

[0484] sending the first signal on discontinuous time domain resources and continuous frequency domain resources; or,

[0485] The first signal is sent on discontinuous time domain resources and discontinuous frequency domain resources.

[0486] Specifically, the transmission resources used to send the first signal may be continuous / discontinuous in the frequency domain / time domain.

[0487] When continuous time domain resources are used, one or more information contained in the first signal can be transmitted in the time domain in different orders.

[0488] When discontinuous time domain resources are used, one or more information contained in the first signal can be transmitted in the time domain in different orders and combinations.

[0489] When continuous frequency domain resources are used, one or more information contained in the first signal can be transmitted in the frequency domain in different orders.

[0490] When discontinuous frequency domain resources are used, one or more information contained in the first signal can be transmitted in the frequency domain in different orders and combinations.

[0491] In a scenario where transmission resources are discontinuous, the multiple information contained in the first signal can be divided into different sub-segments. A sub-segment contains one or more information. The transmission order of different sub-segments can be changed, and the transmission order of different information in a sub-segment can also be changed.

[0492] The signal sending method provided by the embodiment of the present disclosure supports the first device to receive signals on continuous / discontinuous time domain / frequency domain resources, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while providing a certain degree of flexibility for the scheduling of transmission resources.

[0493] The technical solution of the embodiment of the present disclosure is further described below through a specific example.

Its content may include one or more of the following options: energy collection information, synchronization information, initial access information, authentication information, positioning information, integrity verification information, activation information, reporting request information, target terminal device ID, target group terminal device identifier, etc. In other words, the first signal carries one or more of the aforementioned information. One or more pieces of information correspond to A-IoT devices of different device types. Different device types include Type A, Type B, and Type C.

[0498] The A-IoT device determines, based on a protocol predefined or second device preconfigured method, the signal waveforms corresponding to different information, the manner and order in which the signals corresponding to different information constitute the first signal, and the time-frequency resources occupied by information corresponding to different device types in the first signal. The A-IoT device receives the first signal based on the aforementioned information.

[0499] The pre-configuration method may be one or more of a system message, RRC information, MAC CE, DCI, etc. The signal waveform may adopt ASK, FSK, OFDM, etc. The method in which signals corresponding to different information constitute the first signal may be time division multiplexing, frequency division multiplexing, code division multiplexing, etc.

[0500] The transmission resources occupied by the first signal may be continuous or discontinuous in the time domain and / or frequency domain.

[0501] Step B: The A-IoT device sends a response signal to the second device.

[0502] The response signal is a bit stream signal including at least one response information, which carries AI

[0503] The response information of the OT device to part or all of the information carried in the first signal. The transmission resources occupied by the response signal can be continuous or discontinuous in the time domain and / or frequency domain.
