[0004] However, in the above situation, there may be a problem of mutual interference between devices in the environmental IoT and devices outside the environmental IoT. For example, information sent by one device in the environmental IoT to another device in the environmental IoT may interfere with the data transmission of devices outside the environmental IoT. Summary of the Invention

[0005] This disclosure provides a communication method, system, electronic device, storage medium, and program product that can solve the technical problem of mutual interference between devices in the environmental Internet of Things and devices in the non-environmental Internet of Things in the related art.

[0006] On the one hand, a communication method is provided, applied to a target entity, the method including:

The first signaling indicates information related to data transmission with the target entity when environmental IoT and non-environmental IoT share transmission resources. The target entity is an entity within either environmental IoT or a non-environmental IoT.

[0033] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0034] It should be noted that, in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0036] In the description of this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "more than one" means two or more.

[0037] The following explains the concepts that may be involved in the embodiments of this disclosure:

[0038] With the continuous advancement of radio technology, a wide variety of radio services have emerged. Besides cellular services between base stations and terminals, Long Term Evolution (LTE) and New Radio (NR) systems also include services such as the Internet of Things (IoT). Typical IoT services in LTE systems include Narrow Band Internet of Things (NB-IoT), Machine Type Communication (MTC), and eMTC. Typical IoT services in NR systems include Reduced Capability (RedCap) and eRedCap. IoT services refer to communication between base stations and IoT devices. These IoT devices are typically powered by traditional batteries with limited lifespans. Maintaining the continuous operation of IoT devices and replacing batteries can be very challenging under extreme environmental conditions. On the other hand, increasingly widespread large-scale commercial use cases (warehousing, logistics, supply chain, smart homes, environmental monitoring, smart agriculture, item finding, shopping malls, venue guides, medical device status modification, device activation / deactivation, elderly healthcare, etc.) require very small-sized, longer-lifetime IoT devices. Therefore, in systems such as LTE, NR, short-range network coexistence, WiFi, Bluetooth, vehicle-to-everything (V2X) systems, industrial internet systems, Star Alliance systems, and future network coexistence systems, it is necessary to consider ultra-low power consumption, ultra-low complexity, and ultra-low cost IoT devices that do not have battery power. For example, the electrical energy required for the operation of IoT devices comes from energy collected from radio frequency signals in the surrounding environment, or from other forms of energy such as solar energy, wind energy, mechanical vibration, etc., or from electrical energy collected through circuit coupling. These types of IoT devices that do not have battery power are called environmental IoT or passive IoT (A-IoT) or P-IoT. More broadly, for embedded active / semi-active IoT devices, if the power supply of the active / semi-active IoT device is exhausted and it can degrade into a passive IoT device, this type of device is also called A-IoT or P-IoT.

[0039] A-IoT devices can be broadly categorized into two types: the first type communicates by modulating and reflecting received carrier signals; the second type has independent signal generation capabilities, enabling communication by generating a complete communication signal link. More broadly, there is another type of device that possesses both of these capabilities: it communicates by modulating and reflecting received carrier signals and has independent signal generation capabilities, enabling communication by generating a complete communication signal link. For example, the carrier signal can be an unmodulated continuous waveform or an unmodulated carrier wave; these two concepts are equivalent and are referred to as CW in this paper. For example, CW can be a sine wave, cosine wave, etc. A-IoT networks can be mainly divided into four categories: The first type of topology is where network nodes communicate directly with A-IoT devices; the second type of topology is where there are relay nodes between network nodes and A-IoT devices; the third type of topology is where there are auxiliary nodes between network nodes and A-IoT devices, which can assist A-IoT devices in downlink or uplink communication; and the fourth type of topology is where terminal nodes communicate directly with A-IoT devices. For example, network nodes, relay nodes, auxiliary nodes, and terminal nodes can also act as readers (also known as interrogators), and A-IoT devices can also act as tags.

[0040] In situations where devices in the environmental IoT and devices outside the environmental IoT can share transmission resources or use adjacent transmission resources separately, mutual interference may occur. For example, there's the time-domain coexistence problem: if user equipment using other radio access technologies (e.g., NR systems, user equipment under base station coverage) is near a reader, the reader's signal will arrive at the user equipment earlier than the base station's signal. In this case, the user equipment's receiving window might receive orthogonal frequency-division multiplexing (OFDM) symbols that are not transmitted by the base station. Similarly, if a tag is near a base station, the base station's signal will arrive at the tag earlier than the reader's signal. In this case, the tag's receiving window might receive OFDM symbols from the base station. There's also the frequency-domain coexistence problem: environmental IoT shares the same frequency resources with other radio access technologies (e.g., NR systems), and interference may also be introduced due to frequency offset or spectrum leakage.

[0041] To address the aforementioned technical problems, this disclosure provides a communication method. By using a first signaling that can indicate information related to data transmission with a target entity in the case of shared transmission resources between an environmental IoT and a non-environmental IoT, the method can reliably reflect the potential impact on the target entity during data transmission, or the potential impact on other entities. Therefore, by transmitting data through the first signaling, interference from other entities during data transmission or interference to other entities can be reduced, thereby improving the reliability of communication.

[0042] The communication method provided in this disclosure can be applied to systems with various communication standards. For example, the systems to which the communication method provided in this disclosure is applicable include, but are not limited to, Long Term Evolution (LTE) systems, various versions of LTE-based systems, 5G systems, future mobile communication networks (e.g., 6G mobile communication networks), or multiple converged communication systems. Furthermore, the communication method provided in this disclosure can also be applied to future-oriented network coexistence systems.

[0043] For example, the above communication method can be applied to the network coexistence system shown in FIG1. ​​As shown in FIG1, the network coexistence system includes: a first entity 101, a second entity 102, a third entity 103, and a fourth entity 104.

[0044] For example, a network coexistence system includes an environmental IoT and a non-environmental IoT, which share transmission resources; entities in the network coexistence system notify each other of information related to data transmission when the environmental IoT and the non-environmental IoT share transmission resources via a first signaling; and entities transmit data based on the first signaling.

[0045] The first entity 101 is used to send messages, information or signaling for reading and writing information to the second entity 102.

[0046] In some embodiments, the first entity 101 may be a reader / writer.

[0047] The second entity 102 is used to receive messages, information or signaling from the first entity 101; or to send information in the second entity 102 to the first entity 101 based on messages, information or signaling from the first entity 101; or to modify information stored in the first entity 101 based on messages, information or signaling from the first entity 101.

[0048] In some embodiments, the second entity 102 may be an environmental IoT device.

[0049] In some embodiments, the first entity 101 and the second entity 102 belong to the environmental Internet of Things.

[0050] The third entity 103 is used to send information, signaling, messages, or data to the fourth entity 104; or to receive information, signaling, messages, or data from the fourth entity 104.

[0051] In some embodiments, the third entity 103 may include at least one of the following: a network node (such as a base station), a management node (such as an access point (AP) for Wireless Fidelity (WIFI), a master node for Bluetooth, or a G-granting node for StarSpark).

[0052] The fourth entity 104 is used to receive information, signaling, messages, or data from the third entity 103; or to send information, signaling, messages, or data to the third entity 103.

[0053] In some embodiments, the fourth entity 104 may include at least one of the following: user equipment, terminal equipment (such as WiFi terminal node, Bluetooth Slave node, or StarSpark T terminal node).

[0054] In some embodiments, the third entity 103 and the fourth entity 104 belong to non-environmental Internet of Things.

[0055] In some embodiments, the terminal can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can also be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of this application do not limit the application scenarios. The term "terminal" can sometimes also refer to a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, or UE device, etc., but the embodiments of this application do not limit this to these terms.

[0056] In some embodiments, the base station may be a base station in Long Term Evolution, Long Term Evolution Advanced (LTEA) or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future network coexistence system, etc. The base station may include various macro base stations, micro base stations, femtobase stations, wireless remote extensions, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity devices, or various network-side devices such as primary cells and secondary cells.

[0057] It should be noted that Figure 1 is only an exemplary framework diagram, and the number of devices included in Figure 1 and the names of each device are not limited.

[0058] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0059] The communication method provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0060] The communication method provided in this disclosure can be applied to a target entity in the network coexistence system shown in Figure 1; the target entity is an entity in the environmental Internet of Things (IoT) or a non-environmental IoT. Figure 2 shows a flowchart of a communication method, which includes the following steps S201-S202:

[0061] S201, Receive the first signaling.

[0062] S202. Data transmission is performed based on the first signaling.

[0063] For example, the first signaling is used to indicate information related to data transmission with a target entity when environmental IoT and non-environmental IoT share transmission resources.

[0064] In situations where environmental IoT and non-environmental IoT share transmission resources, devices in environmental IoT and non-environmental IoT share frequency domain resources on the same time domain resources. For example, devices in environmental IoT and non-environmental IoT can transmit data using mutually orthogonal frequency domain resources (such as subcarriers) on the same frame (or subframe, time slot, or symbol).

[0065] For example, suppose there is a symbol 1, which includes 7 subcarriers; in this case, devices in the environmental IoT can use 3 subcarriers on symbol 1, and devices outside the environmental IoT can use 4 subcarriers on symbol 1 other than the 3 subcarriers.

[0066] When devices in the environmental IoT share transmission resources with devices outside the environmental IoT, such as when one device in the environmental IoT sends data to another device in the environmental IoT, it may interfere with the data transmission of the devices outside the environmental IoT.

[0067] For example, when both parties share transmission resources, information sent by one device in the environmental IoT to another device in the environmental IoT may be received by a device outside the environmental IoT, thereby interfering with the device outside the environmental IoT. The interference caused by an environmental IoT device to a non-environmental IoT device is similar to the interference caused by a non-environmental IoT device to an environmental IoT device.

[0068] Since the first signaling can indicate information related to data transmission with the target entity in the case of shared transmission resources between environmental IoT and non-environmental IoT, the first signaling can reliably reflect the potential impact on the target entity during data transmission, or the potential impact on other entities; thus, data transmission through the first signaling can reduce interference from other entities during data transmission, or reduce interference to other entities, thereby improving the reliability of communication.

[0069] In some embodiments, the target entity can transmit data using OFDM symbols.

[0070] In some embodiments, the content of the data transmission includes at least one of the following: business data and control signaling.

[0071] In some embodiments, in non-environmental IoT, business data can be referred to as user plane data; control signaling can be referred to as control plane signaling.

[0072] In some embodiments, in the Internet of Things (IoT) environment, business data can be data sent by the reader to the tag, or data read by the reader from the tag; control signaling can include, indicate, encompass, or characterize control information, control commands, or control instructions sent by the reader to the tag.

[0073] In some embodiments, the environmental Internet of Things (IoT) includes a first entity and a second entity, while the non-environmental IoT includes a third entity and a fourth entity.

[0074] In some embodiments, the target entity is any one of the first entity, the second entity, the third entity, or the fourth entity.

[0075] In some embodiments, the first entity includes a reader / writer.

[0076] In some embodiments, the second entity includes an environmental IoT device.

[0077] In some embodiments, the third entity includes a network node.

[0078] In some embodiments, the fourth entity includes a terminal.

[0079] In some embodiments, the first signaling is used to indicate at least one of the following: propagation time, delay time, advance time, and frequency domain resource configuration information.

[0080] For example, the propagation time includes the duration of data transmission between any two entities among the first, second, third, or fourth entities; the frequency domain resource configuration information is used to configure guard bands in the frequency domain resources used by the environmental IoT and / or in the frequency domain resources not used by the environmental IoT.

[0081] In some embodiments, the transmission time includes at least one of the following: a first propagation time, a second propagation time, a third propagation time, a fourth propagation time, a fifth propagation time, a sixth propagation time, a seventh propagation time, and an eighth propagation time. For example, the first propagation time is the duration of signal propagation from the third entity to the fourth entity; the second propagation time is the duration of signal propagation from the first entity to the fourth entity; the third propagation time is the duration of signal propagation from the first entity to the second entity; the fourth propagation time is the duration of signal propagation from the third entity to the second entity; the fifth propagation time is the duration of signal propagation from the fourth entity to the third entity; the sixth propagation time is the duration of signal propagation from the second entity to the third entity; the seventh propagation time is the duration of signal propagation from the second entity to the first entity; and the eighth propagation time is the duration of signal propagation from the fourth entity to the first entity.

[0082] For two entities, the propagation time of a signal when one entity sends a signal to another entity is not necessarily the same as the propagation time of a signal when the other entity sends a signal to the first entity.

[0083] The guard band is a frequency band reserved in the frequency domain resources that is not used for data transmission.

[0084] In some embodiments, the propagation time includes a first propagation time and a second propagation time; the first propagation time is the duration of signal propagation from the third entity to the fourth entity; the second propagation time is the duration of signal propagation from the first entity to the fourth entity; when the first propagation time is greater than or equal to the second propagation time, data transmission is performed based on the first signaling, including at least one of the following:

[0085] The target entity includes the first entity, which sends data with a delay time.

[0086] The target entity includes a fourth entity, which receives data based on an advance processing window and based on the processing window when receiving data.

[0087] Since environmental IoT and non-environmental IoT share transmission resources, the third entity and the first entity share a time domain resource, and the frequency domain resources used by the third entity to transmit data and the frequency domain resources used by the first entity to transmit data are mutually orthogonal.

[0088] If the first propagation time is greater than or equal to the second propagation time, it means that the data sent by the first entity may arrive at the fourth entity earlier than the data sent by the third entity to the fourth entity. In this case, for the fourth entity, within the time window of receiving data from the third entity, the time domain resources corresponding to the data or signals received from the first entity and the time domain resources corresponding to the data or signals received from the third entity may not form a complete time domain resource. At this time, the data from the first entity may interfere with the data from the third entity, that is, there is inter-carrier interference. The orthogonality of the data sent by each party in the frequency domain may be affected. In this case, the fourth entity may not be able to correctly demodulate the data sent by the third entity.

[0089] For example, suppose the first entity and the third entity use different subcarriers on symbol 1 for data transmission. If the first propagation time is greater than or equal to the second propagation time, the fourth entity may only be able to receive symbol 1 completely from the third entity within the processing window for receiving symbol 1, but not completely from the first entity. In this case, symbol 1 is incomplete for the fourth entity, the orthogonality between the subcarriers on symbol 1 may be destroyed, there is inter-carrier interference, and since the first entity is closer to the fourth entity than the third entity, the signal strength from the first entity is stronger, resulting in greater interference. In this case, the fourth entity may not be able to correctly demodulate the signal to obtain data.

[0090] When the first entity sends data, the data transmission is delayed based on the delay time, which can postpone the arrival time of the data sent by the first entity to the fourth entity. In this way, it can be ensured that the arrival time of the data from the third entity to the fourth entity is not too different from the arrival time of the data from the first entity to the fourth entity, ensuring that the data from both parties is complete in the time domain, reducing the interference of the signal from the first entity to the fourth entity, and thus ensuring that the fourth entity can correctly demodulate and obtain the data from the third entity.

[0091] For example, as shown in FIG3, a data transmission schematic diagram provided by an embodiment of the present disclosure includes: OFDM symbols transmitted by a third entity and OFDM symbols transmitted by a first entity; and OFDM symbols received by a fourth entity from the first and third entities. In the figure, CP is used to represent a cyclic prefix, S1 is used to represent the first OFDM symbol, S2 is used to represent the second OFDM symbol, PT (propagation time)1 is the first propagation time, PT2 is the second propagation time, and the receiving processing window is used to indicate the time window for the fourth entity to receive OFDM symbols from the third entity. As can be seen from FIG3, when PT1 is greater than PT2, the fourth entity cannot completely receive the OFDM symbols from the first entity within the receiving processing window. At this time, the OFDM symbols received by the fourth entity from the third entity and the OFDM symbols received from the first entity cannot form a complete OFDM symbol, and the orthogonality of the subcarriers on the OFDM symbol is destroyed. At this time, the fourth entity may not be able to demodulate the signal accurately and reliably.

[0092] Figure 4 illustrates another data transmission method provided by an embodiment of this disclosure. Figure 4 shows the data transmission between the first entity, the third entity, and the fourth entity when the first entity in Figure 3 delays data transmission based on a delay time (DT in Figure 4). As shown in Figure 4, when the first entity delays data transmission based on the delay time, the fourth entity can completely receive the OFDM symbols from both the first and third entities. In this case, the OFDM symbols from both parties can form a complete OFDM symbol, thus ensuring the orthogonality of the subcarriers on the OFDM symbol and guaranteeing communication reliability.

[0093] In some embodiments, if the first entity delays sending data, the second entity may use a processing window earlier to receive data from the first entity.

[0094] Without a pre-processing window, the fourth entity can be guaranteed to receive the data from the third entity completely, but it cannot be guaranteed that the fourth entity will receive the data from the first entity completely. With a pre-processing window, the fourth entity can receive the data from the first entity completely. Furthermore, due to the presence of the cyclic prefix, the pre-processing window can still receive the data from the third entity completely. In this way, the data from both parties can be guaranteed to be complete in the temporal domain, reducing the interference from the data from the first entity to the fourth entity, thereby ensuring that the fourth entity can correctly demodulate the data from the third entity.

[0095] For example, as shown in FIG5, which is a schematic diagram of another data transmission provided by an embodiment of the present disclosure, it is used to indicate the processing window of the fourth entity in FIG3 receiving data based on the advance time (AT (advance time) in FIG5). As can be seen from FIG5, when the fourth entity receives data based on the advance processing window, it can completely receive the OFDM symbol from the first entity. Furthermore, since the OFDM symbol from the third entity has a cyclic prefix containing information from the tail of the OFDM symbol, the OFDM symbol from the third entity can be completely received based on the advance processing window. In this way, the OFDM symbols from both parties can form a complete OFDM symbol, which can guarantee the orthogonality of the subcarriers on the OFDM symbol and ensure the reliability of communication.

[0096] When the first entity sends data, it delays the data transmission based on the delay time; and when the fourth entity receives data, it advances the processing window based on the advance time and receives the data based on the processing window. This ensures that the data from both parties is complete in the time domain and reduces the interference caused by the data from the first entity to the fourth entity, thereby ensuring that the fourth entity can correctly demodulate and obtain the data from the third entity.

[0097] For example, as shown in FIG6, which is a schematic diagram of another data transmission according to an embodiment of the present disclosure, it illustrates the data transmission of the first entity in FIG3 that delays data transmission based on the delay time, and the fourth entity that advances the processing window based on the advance time. As can be seen from FIG6, the first entity delays data transmission, and the fourth entity advances the processing window, which ensures that the fourth entity completely receives the OFDM symbols from the first entity and the OFDM symbols from the third entity. The OFDM symbols from both parties can form a complete OFDM symbol. In this way, the orthogonality of the subcarriers on the OFDM symbol can be guaranteed, thus ensuring the reliability of communication.

[0098] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the condition that it is greater than or equal to the first time; for example, the first time is the difference between the first propagation time and the second propagation time.

[0099] The delay time being greater than or equal to the first time ensures that after the first entity delays sending data, the fourth entity receives the data from the first entity at a time later than or equal to the time it receives the data from the third entity. This ensures the integrity of the data received by the fourth entity from the first entity, thereby guaranteeing that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0100] If the advance time is greater than or equal to the first time, it can be guaranteed that the fourth entity can receive the data from the first entity completely after the advance processing window, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0101] In some embodiments, when the first propagation time is greater than or equal to the second propagation time, the first entity sends data with a delayed transmission time based on the delay time; and when the fourth entity receives data, it processes the data in advance based on the advance time and receives the data based on the processing window, wherein the sum of the delay time and the advance time is greater than or equal to the first time.

[0102] If the sum of the delay time and the advance time is greater than or equal to the first time, it can ensure the integrity of the data received by the fourth entity from the first entity, thereby ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0103] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the following condition: greater than or equal to the first time and less than or equal to the second time; for example, the first time is the difference between the first propagation time and the second propagation time; the second time is the sum of the first time and the duration corresponding to the cyclic prefix.

[0104] The delay time being greater than or equal to the first time and less than or equal to the second time ensures that the time when the data from the first entity arrives at the fourth entity is later than or equal to the time when the data from the third entity arrives at the fourth entity, and also ensures that the time when the data from the first entity arrives at the fourth entity is not too late, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0105] The advance time is greater than or equal to the first time and less than or equal to the second time, which ensures that the fourth entity can receive the data from the first entity completely, and also ensures that the first entity receives the data from the third entity and that the data from the first entity is not received too early, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0106] The sum of the delay time and the advance time is greater than or equal to the first time and less than or equal to the second time, which ensures that the first entity sends data at a time that is not too late and that the fourth entity receives data from the third entity and data from the first entity at a time that is not too early, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0107] In some embodiments, the first signaling is sent by any one of the first entity, second entity, third entity, or fourth entity other than the target entity.

[0108] In some embodiments, the target entity includes a first entity, the first signaling may include a first transmission time, and the first entity stores a second transmission time; the first entity may determine a delay time based on the first transmission time and the second transmission time.

[0109] In some embodiments, the target entity includes a first entity, and the first signaling may include a first transmission time and a second transmission time; the first entity may determine a delay time based on the first transmission time and the second transmission time.

[0110] In some embodiments, the target entity includes a first entity, and the first signaling may include a delay time.

[0111] In some embodiments, the first signaling is sent from the second entity, the third entity, or the fourth entity to the first entity.

[0112] In some embodiments, the second, third, or fourth entity may acquire the first transmission time and the second transmission time; and determine the delay time based on the first and second transmission times.

[0113] In some embodiments, the target entity includes a fourth entity, the first signaling may include a second transmission time, the fourth entity stores the first transmission time, and the fourth entity may determine an advance time based on the first transmission time and the second transmission time.

[0114] In some embodiments, the target entity includes a fourth entity, and the first signaling may include a first transmission time and a second transmission time; the fourth entity may determine an advance time based on the first transmission time and the second transmission time.

[0115] In some embodiments, the target entity includes a fourth entity, and the first signaling may include a lead time.

[0116] In some embodiments, the first signaling is sent by a first entity, a second entity, or a third entity.

[0117] In some embodiments, a first entity, a second entity, or a third entity may acquire a first transmission time and a second transmission time; and determine an advance time based on the first transmission time and the second transmission time.

[0118] In some embodiments, the first signaling may include lead time and delay time. The target entity includes a first entity and a fourth entity.

[0119] In some embodiments, a first signaling message, including advance time and delay time, is sent by a second entity or a third entity to a first entity and a fourth entity.

[0120] In some embodiments, the propagation time includes a third propagation time and a fourth propagation time; the third propagation time is the duration of signal propagation from the first entity to the second entity; the fourth propagation time is the duration of signal propagation from the third entity to the second entity; when the third propagation time is greater than or equal to the fourth propagation time, data transmission is performed based on the first signaling, including at least one of the following:

[0121] The target entity includes a third entity, which sends data with a delay time.

[0122] The target entity includes a second entity, which receives data based on an advance processing window and based on the processing window when receiving data.

[0123] If the third propagation time is greater than or equal to the fourth propagation time, it means that within the time window during which the second entity receives the data sent by the first entity, the data received from the third entity may not form a complete time domain resource with the data from the first entity. In this case, the carrier corresponding to the data from the third entity may interfere with the carrier corresponding to the data from the first entity, and the first entity may not be able to correctly demodulate the data from the first entity.

[0124] When the third entity sends data, the data transmission is delayed based on the delay time, which postpones the arrival time of the data from the third entity to the second entity. In this way, it can be ensured that the time difference between the data from the first entity and the data from the third entity when they arrive at the second entity is not too large, ensuring that the data from both parties is complete in terms of time domain resources, and ensuring that the second entity can correctly demodulate and obtain the data from the first entity.

[0125] For example, as shown in FIG7, another data transmission diagram provided by an embodiment of the present disclosure includes: OFDM symbols transmitted by a third entity and OFDM symbols transmitted by a first entity; and OFDM symbols received by a second entity from the first and third entities. In the figure, CP is used to represent the cyclic prefix, S1 is used to represent the first OFDM symbol, S2 is used to represent the second OFDM symbol, PT (propagation time) 3 is the third propagation time, PT4 is the fourth propagation time, and the receiving processing window is used to indicate the time window for the second entity to receive OFDM symbols from the first entity. As can be seen from FIG3, when PT3 is greater than PT4, the second entity cannot completely receive the OFDM symbols from the third entity within the receiving processing window. At this time, the OFDM symbols received by the second entity from the third entity and the OFDM symbols from the first entity cannot form a complete OFDM symbol, and the orthogonality of the subcarriers on the OFDM symbol is destroyed. At this time, the second entity may not be able to demodulate the signal accurately and reliably.

[0126] For example, as shown in FIG8, another data transmission diagram provided by this embodiment is illustrated, indicating the data transmission between the first entity, the second entity, and the third entity when the third entity transmits data based on a delay time (DT in FIG8). As can be seen from FIG7, when the third entity delays data transmission based on the delay time, the second entity can completely receive the OFDM symbols from the first entity and the OFDM symbols from the third entity. At this time, the OFDM symbols from both parties can form a complete OFDM symbol, thus ensuring the orthogonality of the subcarriers on the OFDM symbol and guaranteeing the reliability of communication.

[0127] The second entity receives data based on the pre-processing window, which ensures that the second entity can receive the data from the third entity completely. Furthermore, due to the presence of the cyclic prefix, the pre-processing window can still receive the data from the first entity completely. In this way, the data from both parties can be guaranteed to be complete in the time domain, reducing the interference of the data from the third entity to the second entity, thereby ensuring that the second entity can correctly demodulate the data from the first entity.

[0128] For example, as shown in FIG9, another data transmission schematic diagram provided by this embodiment is used to indicate the data transmission of the first entity, the second entity, and the third entity in FIG7 when the second entity receives the data in advance based on the advance time (AT in FIG9). As can be seen from FIG9, when the second entity receives the data in advance based on the advance time processing window, the second entity can receive the OFDM symbols from the third entity completely. Furthermore, due to the presence of the cyclic prefix in the OFDM symbols from the first entity, the OFDM symbols from the first entity can still be received completely after the advance processing. At this time, the OFDM symbols from both parties can form a complete OFDM symbol. In this way, the orthogonality of the subcarriers on the OFDM symbol can be guaranteed, thus ensuring the reliability of communication.

[0129] When the third entity sends data, it delays the data transmission based on the delay time; and when the second entity receives data, it advances the processing window based on the advance time and receives the data based on the processing window. This ensures that the data from both parties is complete in the time domain and reduces the interference caused by the data from the third entity to the second entity, thereby ensuring that the second entity can correctly demodulate and obtain the data from the first entity.

[0130] For example, as shown in FIG10, this is a schematic diagram of another data transmission provided by an embodiment of the present disclosure, used to indicate the data transmission of the third entity in FIG7 by delaying data transmission based on the delay time, and the second entity by advancing the processing window based on the advance time. As can be seen from FIG10, the third entity delays data transmission, and the second entity advances the processing window, which can ensure that the second entity completely receives the OFDM symbols from the first entity and the OFDM symbols from the third entity. The OFDM symbols from both parties can form a complete OFDM symbol. In this way, the orthogonality of the subcarriers on the OFDM symbol can be guaranteed, thus ensuring the reliability of communication.

[0131] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the condition that it is greater than or equal to the third time; for example, the third time is the difference between the third propagation time and the fourth propagation time.

[0132] The delay time being greater than or equal to the third time ensures that after the third entity delays sending data, the second entity receives the data from the third entity at a time later than or equal to the time it receives the data from the first entity. This guarantees the integrity of the data received by the second entity from the third entity, thereby ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0133] If the advance time is greater than or equal to the third time, it can be guaranteed that the second entity can receive the data from the third entity completely after the advance processing window, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0134] In some embodiments, when the third propagation time is greater than or equal to the fourth propagation time, the third entity sends data with a delay based on the delay time; and when the second entity receives data, it processes the data in advance based on the advance time and receives the data based on the processing window, wherein the sum of the delay time and the advance time is greater than or equal to the third time.

[0135] If the sum of the delay time and the advance time is greater than or equal to the third time, it can ensure the integrity of the data received by the second entity from the third entity, thereby ensuring that the data from the first entity and the data from the third entity are complete in the time domain resources.

[0136] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the condition that it is greater than or equal to the third time and less than or equal to the fourth time; for example, the third time is the difference between the third propagation time and the fourth propagation time; the fourth time is the sum of the third time and the duration corresponding to the cyclic prefix.

[0137] The delay time being greater than or equal to the third time and less than or equal to the fourth time ensures that after the third entity delays sending data, the second entity receives the data from the third entity at a time later than or equal to the time it receives the data from the first entity. This guarantees the integrity of the data received by the second entity from the third entity and ensures that the data from the third entity is not too late, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0138] The advance time is greater than or equal to the third time and less than or equal to the fourth time. This ensures that the second entity can receive the data from the third entity completely after the advance processing window, and also ensures that the second entity receives the data from the first or third entity too early, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0139] The sum of the delay time and the advance time is greater than or equal to the third time and less than or equal to the fourth time, which ensures that the third entity sends data at a time that is not too late and that the second entity receives data from the first or third entity at a time that is not too early, thus ensuring that the data from the first entity and the data from the third entity are complete in terms of time domain resources.

[0140] In some embodiments, the target entity includes a third entity, the first signaling may include a third transmission time, and the third entity stores a fourth transmission time; the third entity may determine the delay time based on the third transmission time and the fourth transmission time.

[0141] In some embodiments, the target entity includes a third entity, and the first signaling may include a third transmission time and a fourth transmission time; the third entity may determine the delay time based on the third transmission time and the fourth transmission time.

[0142] In some embodiments, the target entity includes a third entity, and the first signaling may include a delay time.

[0143] In some embodiments, the first signaling is sent from the first entity, the second entity, or the fourth entity to the third entity.

[0144] In some embodiments, the first entity, the second entity, or the fourth entity may acquire the third transmission time and the fourth transmission time; and determine the delay time based on the third transmission time and the fourth transmission time.

[0145] In some embodiments, the target entity includes a second entity, the first signaling may include a fourth transmission time, and the second entity stores a third transmission time; the second entity may determine an advance time based on the third transmission time and the fourth transmission time.

[0146] In some embodiments, the target entity includes a second entity, and the first signaling may include a third transmission time and a fourth transmission time; the second entity may determine an advance time based on the third transmission time and the fourth transmission time.

[0148] In some embodiments, the first signaling is sent by a first entity, a third entity, or a fourth entity.

[0149] In some embodiments, the first entity, the third entity, or the fourth entity may acquire the third transmission time and the fourth transmission time; and determine the advance time based on the third transmission time and the fourth transmission time.

[0150] In some embodiments, the first signaling may include lead time and delay time. The target entity includes a second entity and a third entity.

[0151] In some embodiments, a first signaling message, including advance time and delay time, is sent by a first entity or a fourth entity to a second entity and a third entity.

[0152] In some embodiments, the propagation time includes a fifth propagation time and a sixth propagation time; the fifth propagation time is the duration of signal propagation from the fourth entity to the third entity; the sixth propagation time is the duration of signal propagation from the second entity to the third entity; when the fifth propagation time is greater than or equal to the sixth propagation time, data transmission is performed based on the first signaling, including at least one of the following:

[0153] The target entity includes a second entity, which delays data transmission based on a delay time when sending data.

[0154] The target entity includes a third entity. When the third entity receives data, it processes the data based on the advance time window and receives the data based on the processing window.

[0155] If the fifth propagation time is greater than or equal to the sixth propagation time, it means that within the time window when the third entity receives the data from the fourth entity, the time domain resources corresponding to the data from the second entity may not be able to form a complete time domain resource with the time domain resources corresponding to the data from the fourth entity. In this case, the carrier corresponding to the data from the second entity may interfere with the carrier corresponding to the data from the fourth entity, and the third entity may not be able to correctly demodulate the data from the fourth entity.

[0156] When the second entity sends data, it delays the transmission time based on the delay period, which postpones the arrival time of the data from the second entity to the third entity. This ensures that the arrival time of the data from the second entity to the third entity is not significantly different from the arrival time of the data from the fourth entity, guaranteeing the integrity of the data from both parties in the time domain. It also reduces interference from the signal from the second entity to the third entity, thus ensuring that the third entity can correctly demodulate and obtain the data from the fourth entity.

[0157] When the third entity receives data, it can receive data based on the advance time processing window and the processing window. This ensures that the third entity can receive the data from the second entity completely. Furthermore, due to the existence of the cyclic prefix, the third entity can still receive the data from the fourth entity completely. In this way, the data from both parties can be guaranteed to be complete in the time domain, and the interference caused by the data from the second entity to the third entity can be reduced. This ensures that the third entity can correctly demodulate the data from the fourth entity.

[0158] When the second entity sends data, it delays the data transmission based on the delay time; and when the third entity receives data, it advances the processing window based on the advance time and receives the data based on the processing window. This ensures that the data from both parties is complete in the time domain, reduces interference from the data from the second entity to the third entity, and thus ensures that the third entity can correctly demodulate and obtain the data from the fourth entity.

[0159] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the condition that it is greater than or equal to the fifth time; for example, the fifth time is the difference between the fifth propagation time and the sixth propagation time.

[0160] The delay time is greater than or equal to the fifth time, which ensures that the time when the third entity receives the data from the second entity is equal to or later than the time when the third entity receives the data from the fourth entity, and ensures that the data from the second entity and the data from the third entity are complete in terms of time domain resources.

[0161] If the advance time is greater than or equal to the fifth time, it can ensure that the third entity can receive the data from the second entity completely after the advance processing window, and can ensure that the data from the second entity and the data from the third entity are complete in terms of time domain resources.

[0162] The sum of the delay time and the advance time is greater than or equal to the fifth time, which ensures that the time when the third entity receives the data from the second entity is equal to or later than the time when the third entity receives the data from the fourth entity. Furthermore, after the third entity has an advance processing window, it can receive the data from the second entity completely, ensuring that the data from the second entity and the data from the third entity are complete in terms of time domain resources.

[0163] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the following condition: greater than or equal to the fifth time and less than or equal to the sixth time; for example, the fifth time is the difference between the fifth propagation time and the sixth propagation time; the sixth time is the sum of the fifth time and the duration corresponding to the cyclic prefix.

[0164] The delay time is greater than or equal to the fifth time and less than or equal to the sixth time, which ensures that the time when the third entity receives the data from the second entity is equal to or later than the time when the third entity receives the data from the fourth entity, and ensures that the time when the third entity receives the data from the second entity is not too late, and ensures that the data from the second entity and the data from the third entity are complete in terms of time domain resources.

[0165] The advance time is greater than or equal to the fifth time and less than or equal to the sixth time, which ensures that the third entity can receive the data from the second entity completely after the advance processing window, and ensures that the third entity receives the data from the second and fourth entities not too early, and ensures that the data from the second entity and the data from the third entity are complete in terms of time domain resources.

[0166] The sum of the delay time and the advance time is greater than or equal to the fifth time and less than or equal to the sixth time, which ensures that the time when the third entity receives the data from the second entity is equal to or later than the time when the third entity receives the data from the fourth entity, and that the third entity can receive the data from the second entity completely after the advance processing window; it also ensures that the time when the third entity receives the data from the second entity is not too late, and that the time when the third entity receives the data from the second entity and the fourth entity is not too early; and it ensures that the data from the second entity and the data from the third entity are complete in terms of time domain resources.

[0177] In some embodiments, the first signaling may include lead time and delay time. The target entity includes a second entity and a third entity.

[0178] In some embodiments, a first signaling message, including advance time and delay time, is sent by a first entity or a fourth entity to a second entity and a third entity.

[0179] In some embodiments, the propagation time includes a seventh propagation time and an eighth propagation time; the seventh propagation time is the duration of signal propagation from the second entity to the first entity; the eighth propagation time is the duration of signal propagation from the fourth entity to the first entity; when the seventh propagation time is greater than or equal to the eighth propagation time, data transmission is performed based on the first signaling, satisfying at least one of the following:

[0180] The target entity includes a fourth entity, which sends data with a delay time.

[0181] The target entity includes a first entity, which receives data based on an advance processing window and based on the processing window when receiving data.

[0182] If the seventh propagation time is greater than or equal to the eighth propagation time, it means that within the time window when the first entity receives data from the second entity, the time domain resources corresponding to the data from the fourth entity may not be able to form a complete time domain resource with the time domain resources corresponding to the data from the second entity. In this case, the carrier corresponding to the data from the fourth entity may interfere with the carrier corresponding to the data from the first entity, and the second entity may not be able to correctly demodulate the data from the first entity.

[0183] When the fourth entity sends data, the data transmission is delayed based on the delay time, which postpones the arrival time of the data from the fourth entity to the first entity. This ensures that the arrival time of the data from the fourth entity to the first entity is not significantly different from the arrival time of the data from the second entity, guaranteeing the integrity of the data from both parties in the time domain. It also reduces interference from the signal from the fourth entity to the first entity, thereby ensuring that the first entity can correctly demodulate and obtain the data from the second entity.

[0184] When the first entity receives data, it can receive data based on the advance time processing window and the processing window. This ensures that the first entity can receive the data from the fourth entity completely. Furthermore, due to the existence of the cyclic prefix, the first entity can still receive the data from the third entity completely. In this way, it can ensure that the data from both parties is complete in the time domain and reduce the interference of the data from the fourth entity to the first entity. This ensures that the first entity can correctly demodulate the data from the third entity.

[0185] When the fourth entity sends data, it delays the data transmission based on the delay time; and when the first entity receives data, it advances the processing window based on the advance time and receives the data based on the processing window. This ensures that the data from both parties is complete in the time domain and reduces the interference caused by the data from the fourth entity to the first entity, thereby ensuring that the first entity can correctly demodulate and obtain the data from the fourth entity.

[0186] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies the condition that it is greater than or equal to the seventh time; for example, the seventh time is the difference between the seventh propagation time and the eighth propagation time.

[0187] The delay time is greater than or equal to the seventh time, which ensures that the time when the first entity receives the data from the fourth entity is equal to or later than the time when the first entity receives the data from the second entity, and ensures that the data from the fourth entity and the data from the second entity are complete in terms of time domain resources.

[0188] If the advance time is greater than or equal to the seventh time, it can ensure that the first entity can receive the data from the fourth entity completely after the advance processing window, and can ensure that the data from the tenth entity and the data from the second entity are complete in terms of time domain resources.

[0189] The sum of the delay time and the advance time is greater than or equal to the seventh time, which ensures that the time when the first entity receives the data from the fourth entity is equal to or later than the time when the first entity receives the data from the second entity. Furthermore, after the first entity has an advance processing window, it can receive the data from the fourth entity completely, ensuring that the data from the fourth entity and the data from the second entity are complete in terms of time domain resources.

[0190] In some embodiments, any one of the delay time, advance time, and the sum of the delay time and advance time satisfies the condition that it is greater than or equal to the seventh time and less than or equal to the eighth time; for example, the seventh time is the difference between the seventh propagation time and the eighth propagation time; the eighth time is the sum of the seventh time and the duration corresponding to the cyclic prefix.

[0191] The delay time is greater than or equal to the seventh time, which ensures that the time when the first entity receives the data from the fourth entity is equal to or later than the time when the first entity receives the data from the second entity, and ensures that the time when the first entity receives the data from the fourth entity is not too late, and ensures that the data from the fourth entity and the data from the second entity are complete in terms of time domain resources.

[0192] If the advance time is greater than or equal to the seventh time, it can ensure that the first entity can receive the data from the fourth entity completely after the advance processing window, and ensure that the first entity receives the data from the second and fourth entities too early, and ensure that the data from the tenth entity and the data from the second entity are complete in terms of time domain resources.

[0193] The sum of the delay time and the advance time is greater than or equal to the seventh time, which ensures that the time when the first entity receives the data from the fourth entity is equal to or later than the time when the first entity receives the data from the second entity, and that the first entity can receive the data from the fourth entity completely after the advance processing window; and ensures that the time when the first entity receives the data from the fourth entity is not too late, and that the time when the first entity receives the data from the second and fourth entities is not too early, thus ensuring that the data from the fourth entity and the data from the second entity are complete in terms of time domain resources.

[0194] In some embodiments, the target entity includes a fourth entity, the first signaling may include a seventh transmission time, and the second entity stores an eighth transmission time; the second entity may determine the delay time based on the seventh transmission time and the eighth transmission time.

[0205] In some embodiments, a first signaling message, including advance time and delay time, is sent by a second entity or a third entity to a first entity and a fourth entity.

[0206] In some embodiments, the cyclic prefix in data transmission can be an extended cyclic prefix (ECP).

[0207] In some embodiments, resource configuration information is used to configure the location and / or size of the protection strip.

[0208] Due to frequency leakage or frequency offset, devices in the environmental IoT and non-environmental IoT may interfere with each other when using adjacent frequencies. In this case, by configuring the position and / or size of the guard band, the target entity can use frequency domain resources outside the guard band during data transmission. This ensures that the frequency domain resources used by the environmental IoT and non-environmental IoT devices are kept at a greater distance, reducing mutual interference and improving the reliability of data transmission.

[0209] The larger the guard band, the stronger the anti-interference capability of data transmission; the smaller the guard band, the more transmission resources can be used for data transmission.

[0210] In some embodiments, the frequency domain resource configuration information configures the location of the guard band, including at least one of the following:

[0211] The protective strip is configured to be located on the left, right, or both sides of the first resource;

[0212] The protective strip is configured to be located on the left, right, or both sides of the second resource.

[0213] For example, the first resource is the resource used by the environmental Internet of Things (IoT), and the second resource is the resource not used by the environmental IoT.

[0214] By configuring a protection strip to be located on the left, right, or both sides of the first resource, and / or configuring a protection strip to be located on the left, right, or both sides of the second resource, the resources used by the environmental IoT can be isolated from the resources used by the non-environmental IoT, reducing mutual interference between the environmental IoT and the non-environmental IoT and improving the reliability of data transmission.

[0215] In some embodiments, the location of the protective strip can be determined based on the relative positions of the first and second resources.

[0216] In some embodiments, the first resource may be located to the left, right, or middle of the second resource.

[0217] For example, in the allocable frequency domain resources, the first resource can be located to the left of the second resource. In this case, a guard band can be configured to the right of the first resource or to the left of the second resource.

[0218] In some embodiments, the frequency domain resource configuration information configures the size of the guard band, including at least one of the following:

[0219] Configure the number of resource elements (REs) included in the protection band;

[0220] Configure the number of resource blocks (RBs) included in the protection band.

[0221] A resource block may include at least one resource unit.

[0222] In some embodiments, the smallest usable or allocatable resource in the first resource is a resource unit, and the number of resource units and the size of the protection band can be configured in the first resource.

[0223] In some embodiments, the minimum resource that the second resource can use or allocate is a resource block, and the number of resource units and the size of the protection band can be configured in the second resource.

[0224] In some embodiments, resource units or resource blocks can be used uniformly for protection band configuration in both the first and second resources.

[0225] Using resource units or resource blocks for protection band configuration in both the first and second resources can reduce the complexity of protection band configuration and improve its efficiency.

[0226] In some embodiments, the number of resource units, the number of resource blocks, and the total number of resource units and resource blocks are all greater than or equal to the target quantity.

[0227] In some embodiments, the target quantity can be 0.

[0228] In some embodiments, the data transmission satisfies one of the following:

[0229] The first resource is pre-configured with a protection band, which includes at least an integer multiple of the resource units;

[0230] The second resource is pre-configured with a protection band, which includes at least an integer multiple of the resource blocks;

[0231] The first and second resources are pre-configured with protection bands, and the protection bands include at least an integer multiple of resource units and / or an integer multiple of resource blocks;

[0232] Resources that are not configured in the first and second resources are designated as protection zones;

[0233] For example, the first resource is the resource used by the environmental Internet of Things (IoT), and the second resource is the resource not used by the environmental IoT.

[0234] By pre-configuring the conditions that the above data transmission needs to meet, it is faster and simpler than configuring the protection band through signaling.

[0235] In some embodiments, resource configuration information, or the location and / or size of the protection strip, is determined in the following ways:

[0236] The receiver measures the target parameters within the protection zone and feeds back the measurement results of the target parameters to the transmitting entity.

[0237] The launching entity adjusts the position and / or size of the protective strip based on the measurement results of the target parameters.

[0238] The measurement results of the target parameters within the guard band can reflect the communication quality. Therefore, the position and / or size of the guard band can be adjusted based on the measurement results of the target parameters to meet the desired communication quality.

[0239] In some embodiments, resource configuration information, or the location and / or size of the protection strip, is determined in the following ways:

[0240] Receive and measure target parameters within the protection zone of the physical measurement unit;

[0241] Based on the measurement results of the target parameters, the receiving entity determines and feeds back the desired guard band to the transmitting entity;

[0242] The launching entity adjusts the position and / or size of the protection zone based on the desired protection zone.

[0243] The receiving entity can directly determine the desired protection band, which allows the transmitting entity to adjust the protection band more quickly and conveniently.

[0244] In some embodiments, the target parameters include at least one of the following: reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), and signal-to-noise and interference ratio (SINR).

[0245] For example, Figure 11 shows a schematic diagram of a protective strip provided in an embodiment of this disclosure. For instance, the protective strip is located on both sides of resources used by the environmental IoT and resources not used by the environmental IoT. The protective strip can be configured at the resource unit level, the resource block level, or both the resource unit and resource block levels.
