[0032] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0036] The following is an explanation of the concepts that may be involved in the embodiments of the present disclosure:

[0037] With the continuous advancement of radio technology, a variety of radio services have emerged in large numbers. In addition to the cellular services between base stations and terminals, the long-term evolution (LTE) system and the new radio (NR) system also include Internet of Things (IoT) services. Typical IoT services in LTE systems include narrowband Internet of Things (NB-IoT), machine type communication (MTC), and eMTC. Typical IoT services in NR systems include reduced capability / lightweight capability (RedCap) and eRedCap. IoT services are communications between base stations and IoT devices. The IoT devices in the above IoT services are usually powered by traditional batteries with limited lifespans. In some extreme environmental conditions, it may be very challenging to maintain the continuous operation of IoT devices and replace batteries. On the other hand, more and more large-scale commercial scenario use cases (warehousing, logistics, supply chain, smart home, environmental monitoring, smart farming and animal husbandry, finding items, shopping malls, venue guides, medical device status modification, device activation and deactivation, elderly care, etc.) require very small size and longer life cycle IoT devices. Therefore, in LTE systems, NR systems, short-range network coexistence systems, WiFi systems, Bluetooth systems, Internet of Vehicles 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 are not battery-powered. The power required for the operation of IoT devices comes from the 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 energy collected by circuit coupling or energy collected. This type of IoT device that is not battery-powered is called ambient IoT or passive IoT (Passive-IoT), abbreviated as A-IoT or P-IoT. More broadly, for embedded active / semi-active IoT devices, if the power energy of the active / semi-active IoT device is exhausted and can be degraded to a passive IoT device, this type of device is also called A-IoT or P-IoT.

[0038] A-IoT devices can be mainly divided into two categories: the first type of devices can complete communication by modulating and reflecting the received carrier signal; the second type of devices have independent signal generation functions and can complete communication by generating a complete communication signal link. More broadly, there is another type of device that has the above two functions, that is, it can complete communication by modulating and reflecting the received carrier signal, and has independent signal generation functions, which can complete communication by generating a complete communication signal link. The carrier signal can be an unmodulated continuous waveform (continuous waveform) or an unmodulated carrier (carrier wave). The two concepts are equivalent and are both represented by CW in this article. For example, CW can be a sine wave, a cosine wave, etc. A-IoT networks can be mainly divided into four categories: the first topology is that network nodes communicate directly with A-IoT devices; the second topology is that there are relay nodes between network nodes and A-IoT devices; the third topology is that there are auxiliary nodes between network nodes and A-IoT devices, and the auxiliary nodes can assist the downlink or uplink communication of A-IoT devices; the fourth topology is that terminal nodes communicate directly with A-IoT devices; among them, network nodes, relay nodes, auxiliary nodes, and terminal nodes can also be used as readers and writers (also called interrogators), and A-IoT devices can also be used as tags.

[0039] In the case where the devices in the ambient IoT and the devices in the non-ambient IoT can share transmission resources or use adjacent transmission resources respectively, there may be a problem of mutual interference between the devices in the ambient IoT and the devices in the non-ambient IoT. For example, the time domain coexistence problem. If the user equipment of other radio access technologies (such as the NR system, the user equipment under the coverage of the base station) is close to the reader, the signal of the reader will reach the user equipment earlier than the signal of the base station. At this time, the receiving processing window of the user equipment may receive orthogonal frequency-division multiplexing (OFDM) symbols that are not sent by the base station; similarly, if the tag is close to the base station, the signal of the base station will reach the tag earlier than the signal of the reader. At this time, the receiving processing window of the tag may receive OFDM symbols from the base station. For example, the frequency domain coexistence problem. The ambient IoT and other radio access technologies (such as the NR system) share the same frequency resources, which may also introduce interference due to frequency deviation or spectrum leakage.

[0040] To solve the above technical problems, an embodiment of the present disclosure provides a communication method, which can reliably reflect the impact that the target entity may suffer when performing data transmission, or the impact that may be caused to other entities, by indicating the first signaling related to the data transmission with the target entity when the environmental Internet of Things and the non-environmental Internet of Things share transmission resources; therefore, by performing data transmission through the first signaling, it is possible to reduce interference from other entities in the data transmission, or reduce interference caused to other entities, thereby improving the reliability of communication.

[0041] The communication method provided by the embodiments of the present disclosure can be applied to systems of various communication formats. For example, the communication method provided by the embodiments of the present disclosure can be applied to systems including, but not limited to, long-term evolution systems, various versions based on LTE evolution, fifth-generation mobile communication technology (5th generation mobile communication Technology 5G) systems, future mobile communication networks (such as 6G mobile communication networks), or multiple communication convergence systems. In addition, the communication method provided by the embodiments of the present disclosure can also be applied to future-oriented network coexistence systems, etc.

[0042] Exemplarily, the above communication method can be applied to Figure 1 In the network coexistence system, Figure 1 As shown, the network coexistence system includes: a first entity 101 , a second entity 102 , a third entity 103 , and a fourth entity 104 .

[0043] Among them, the network coexistence system includes an environmental Internet of Things and a non-environmental Internet of Things, and the environmental Internet of Things and the non-environmental Internet of Things share transmission resources; entities in the network coexistence system notify each other of information related to data transmission through first signaling when the environmental Internet of Things and the non-environmental Internet of Things share transmission resources; data transmission is performed between entities based on the first signaling.

[0044] The first entity 101 is used to send a message or information or signaling for reading and writing information to the second entity 102.

[0045] In some embodiments, the first entity 101 may be a reader / writer.

[0046] The second entity 102 is used to receive a message, information or signaling from the first entity 101; or to send information in the second entity 102 to the first entity 101 based on the message, information or signaling from the first entity 101; or to modify the information stored in the first entity 101 based on the message, information or signaling from the first entity 101.

[0047] In some embodiments, the second entity 102 may be an ambient IoT device.

[0048] In some embodiments, the first entity 101 and the second entity 102 belong to the ambient Internet of Things.

[0049] The third entity 103 is used to send information or signaling or message or data to the fourth entity 104 ; or to receive information or signaling or message or data from the fourth entity 104 .

[0050] 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) of wireless fidelity (WIFI), a master node (Master) of Bluetooth, and a G granting node of Star Flash).

[0051] The fourth entity 104 is configured to receive information or signaling or message or data from the third entity 103 ; or to send information or signaling or message or data to the third entity 103 .

[0052] In some embodiments, the fourth entity 104 may include at least one of the following: user equipment, terminal equipment (such as a WiFi terminal node, a Bluetooth slave node, a StarFlash T terminal node).

[0053] In some embodiments, the third entity 103 and the fourth entity 104 belong to a non-ambient Internet of Things.

[0054] In some embodiments, the terminal can be a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons and satellites, etc.). The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. A terminal may sometimes also be referred to as 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 equipment, UE agent or UE device, etc., but the embodiments of the present application are not limited to this.

[0055] In some embodiments, the base station may be a base station or an evolved base station (eNB or eNodeB) in long term evolution, long term evolution advanced (LTEA), 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, home base stations, wireless remotes, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity devices, or various network side devices such as primary cells and collaborative cells (secondary cells).

[0056] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of devices included in the , and the names of the individual devices are not limited.

[0057] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0058] The communication method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0059] The communication method provided by the embodiment of the present disclosure can be applied to Figure 1 The target entity in the network coexistence system shown; the target entity is an entity in the ambient Internet of Things or the non-ambient Internet of Things. Figure 2 A flow chart of a communication method is shown, Figure 2 As shown, the communication method includes the following S201-S202:

[0060] S201. Receive a first signaling.

[0061] S202: Perform data transmission based on the first signaling.

[0062] The first signaling is used to indicate information related to data transmission with the target entity when the ambient Internet of Things and the non-ambient Internet of Things share transmission resources.

[0063] It should be understood that when the ambient Internet of Things and the non-ambient Internet of Things share transmission resources, the devices in the ambient Internet of Things and the devices in the non-ambient Internet of Things share frequency domain resources on the same time domain resources. For example, the devices in the ambient Internet of Things and the devices in the non-ambient Internet of Things can use mutually orthogonal frequency domain resources (such as subcarriers) on the same frame (or subframe or time slot or symbol) for data transmission.

[0064] For example, assume that there is symbol 1, which includes 7 subcarriers; at this time, devices in the environmental Internet of Things can use 3 subcarriers on symbol 1, and devices in the non-environmental Internet of Things can use 4 subcarriers on symbol 1 except the 3 subcarriers.

[0065] It should be understood that when devices in the ambient Internet of Things and devices in the non-ambient Internet of Things share transmission resources, data sent by one device in the ambient Internet of Things to another device in the ambient Internet of Things may interfere with the data transmission of the device in the non-ambient Internet of Things.

[0066] For example, when both parties share transmission resources, information sent by one device in the environmental Internet of Things to another device in the environmental Internet of Things may be received by a device in the non-environmental Internet of Things, thereby causing interference to the device in the non-environmental Internet of Things. The interference caused by the device of the environmental Internet of Things to the device of the non-environmental Internet of Things is similar to the interference caused by the device of the non-environmental Internet of Things to the device of the environmental Internet of Things.

[0067] It should be understood that since the first signaling can indicate information related to data transmission with the target entity when the ambient Internet of Things and the non-ambient Internet of Things share transmission resources, the first signaling can reliably reflect the impact that the target entity may suffer when performing data transmission, or the impact that may be caused to other entities; thus, data transmission through the first signaling can reduce interference from other entities in the data transmission, or reduce interference caused to other entities, thereby improving the reliability of communication.

[0068] In some embodiments, the target entity may perform data transmission via OFDM symbols.

[0069] In some embodiments, the content of data transmission includes at least one of the following: business data, control signaling.

[0070] In some embodiments, in a non-ambient IoT, service data may be referred to as user plane data; and control signaling may be referred to as control plane signaling.

[0071] In some embodiments, in the environmental Internet of Things, the business data may be data sent by the reader to the tag, or data read by the reader from the tag; the control signaling may contain or indicate or include or represent control information or control commands or control instructions sent by the reader to the tag.

[0072] In some embodiments, the ambient Internet of Things includes a first entity and a second entity, and the non-ambient Internet of Things includes a third entity and a fourth entity.

[0073] In some embodiments, the target entity is any one of the first entity, the second entity, the third entity, or the fourth entity.

[0074] In some embodiments, the first entity includes a reader / writer.

[0075] In some embodiments, the second entity comprises an ambient IoT device.

[0076] In some embodiments, the third entity comprises a network node.

[0077] In some embodiments, the fourth entity comprises a terminal.

[0078] 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.

[0079] Among them, the propagation time includes the duration of data transmission between any two entities among the first entity, the second entity, the third entity or the fourth entity; the frequency domain resource configuration information is used to configure a protection band in the frequency domain resources used by the environmental Internet of Things and / or the frequency domain resources used by the non-environmental Internet of Things.

[0080] 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. The first propagation time is the duration of the signal propagation from the third entity to the fourth entity; the second propagation time is the duration of the signal propagation from the first entity to the fourth entity; the third propagation time is the duration of the signal propagation from the first entity to the second entity; the fourth propagation time is the duration of the signal propagation from the third entity to the second entity; the fifth propagation time is the duration of the signal propagation from the fourth entity to the third entity; the sixth propagation time is the duration of the signal propagation from the second entity to the third entity; the seventh propagation time is the duration of the signal propagation from the second entity to the first entity; and the eighth propagation time is the duration of the signal propagation from the fourth entity to the first entity.

[0081] It should be understood that, for two entities, the propagation time of a signal when one entity sends a signal to the other entity is not necessarily the same as the propagation time of the signal when the other entity sends a signal to the one entity.

[0082] It should be understood that the guard band is a frequency band reserved in the frequency domain resources and not used for data transmission.

[0083] In some embodiments, the propagation time includes a first propagation time and a second propagation time; the first propagation time is a duration of signal propagation from the third entity to the fourth entity; the second propagation time is a 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:

[0084] The target entity includes a first entity, and when the first entity sends data, the data is sent after a delay based on a delay time;

[0085] The target entity includes a fourth entity. When receiving data, the fourth entity advances the processing window based on the advance time and receives the data based on the processing window.

[0086] It should be understood that since the environmental Internet of Things and the non-environmental Internet of Things 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 send data and the frequency domain resources used by the first entity to send data are orthogonal to each other.

[0087] It should be understood that when 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. At this time, for the fourth entity, within the time window for receiving data from the third entity, the time domain resources corresponding to the data or signal received from the first entity and the time domain resources corresponding to the data or signal from the third entity may not constitute 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 interference between subcarriers, and the orthogonality of the data sent by each party in the frequency domain may be affected. At this time, the fourth entity may not be able to correctly demodulate and obtain the data sent by the third entity.

[0088] Exemplarily, assuming that the first entity and the third entity respectively use different subcarriers on symbol 1 for data transmission, when the first propagation time is greater than or equal to the second propagation time, the fourth entity may only be able to completely receive symbol 1 from the third entity within the processing window for receiving symbol 1, but cannot completely receive symbol 1 from the first entity. At this time, for the fourth entity, symbol 1 is incomplete, the orthogonality between the subcarriers on symbol 1 may be destroyed, and there is interference between subcarriers. Moreover, since the first entity is closer to the fourth entity than the third entity, the strength of the signal from the first entity is stronger, and the interference generated is greater. At this time, the fourth entity may not be able to correctly demodulate the signal to obtain data.

[0089] It should be understood that when the first entity sends data, delaying the sending of the data based on the delay time can delay the time for the data sent by the first entity to arrive at the fourth entity; in this way, it can be ensured that the time for the data from the third entity to arrive at the fourth entity and the time for the data from the first entity to arrive at the fourth entity will not differ too much, thereby ensuring that the data from both parties are complete in time domain resources, and reducing the interference caused by the signal 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.

[0090] For example, Figure 3As shown, it is a schematic diagram of data transmission provided by an embodiment of the present disclosure, including: OFDM symbols sent by a third entity, OFDM symbols sent by a first entity; OFDM symbols received by a fourth entity from the first entity and the third entity. 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 (processing window) is used to indicate the time window in which the fourth entity receives the OFDM symbol from the third entity. Combined with Figure 3 It can be seen that 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 from the first entity cannot form a complete OFDM symbol, and the orthogonality of the subcarriers on the OFDM symbols is destroyed. At this time, the fourth entity may not be able to accurately and reliably demodulate the signal.

[0091] like Figure 4 As shown, it is a schematic diagram of another data transmission provided by an embodiment of the present disclosure. Figure 4 for Figure 3 The first entity in the Figure 4 DT (delay time) is a schematic diagram of data transmission by the first entity, the third entity, and the fourth entity when data is sent after a delay of DT (delay time). Figure 4 It can be seen that when the first entity delays sending data based on the delay time, the fourth 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. In this way, the orthogonality of the subcarriers on the OFDM symbols can be guaranteed, and the reliability of communication is guaranteed.

[0092] In some embodiments, when the first entity delays sending data, the second entity may advance a processing window for receiving data from the first entity.

[0093] It should be understood that the non-advanced processing window can ensure that the fourth entity completely receives the data from the third entity, but cannot ensure that the fourth entity completely receives the data from the first entity; the fourth entity receives data based on the advanced processing window, which can ensure that the fourth entity can completely receive the data from the first entity, and due to the existence of the cyclic prefix, the advanced processing window can still completely receive the data from the third entity. In this way, it can be ensured that the data from both parties are complete in time domain resources, and the interference caused by the data from the first entity to the fourth entity can be reduced, thereby ensuring that the fourth entity can correctly demodulate and obtain the data from the third entity.

[0094] For example, Figure 5 FIG. 1 is a schematic diagram of another data transmission provided by an embodiment of the present disclosure, for indicating Figure 3 The fourth entity is based on the lead time ( Figure 5 The figure shows the processing window receiving data in advance of AT (advance time). Figure 5 It can be seen that when the fourth entity receives data based on the advanced processing window, it can completely receive the OFDM symbol from the first entity, and because there is a cyclic prefix containing the information of the tail of the OFDM symbol before the OFDM symbol from the third entity, the OFDM symbol from the third entity can be completely received based on the advanced processing window. In this way, the OFDM symbols from both parties can form a complete OFDM symbol, which can ensure the orthogonality of the subcarriers on the OFDM symbol and ensure the reliability of communication.

[0095] It should be understood that when the first entity sends data, the data is sent after a delay time; and when the fourth entity receives data, the processing window is advanced based on the advance time and the data is received based on the processing window. This ensures that the data from both parties are complete in the time domain resources, and reduces the interference of 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.

[0096] For example, Figure 6 FIG. 1 is a schematic diagram of another data transmission provided by an embodiment of the present disclosure, for indicating Figure 3 In the example, the first entity delays sending data based on the delay time, and the fourth entity advances the data transmission of the processing window based on the advance time. Figure 6 It can be seen that the first entity delays sending data and the fourth entity raises the processing window, which can ensure 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 symbols can be guaranteed, and the reliability of communication is guaranteed.

[0097] In some embodiments, any one of the delay time, the advance time, and the sum of the delay time and the advance time satisfies: being greater than or equal to a first time; wherein the first time is the difference between the first propagation time and the second propagation time.

[0098] It should be understood that the delay time is greater than or equal to the first time, which can ensure that after the first entity delays sending data, the time when the fourth entity receives the data from the first entity is later than or equal to the time when the data from the third entity is received, thereby ensuring 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 time domain resources.

[0106] In some embodiments, the first signaling is sent by any one of the first entity, the second entity, the third entity, or the fourth entity except the target entity.

[0107] 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 the delay time based on the first transmission time and the second transmission time.

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

[0110] In some embodiments, the first signaling is sent by the second entity or the third entity or the fourth entity to the first entity.

[0111] In some embodiments, the second entity or the third entity or the fourth entity may obtain the first transmission time and the second transmission time; and determine the delay time based on the first transmission time and the second transmission time.

[0112] In some embodiments, the target entity includes a fourth entity, the first signaling may include the second transmission time, and the first transmission time is stored in the fourth entity; the fourth entity may determine the advance time based on the first transmission time and the second transmission time.

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

[0115] In some embodiments, the first signaling is sent by the first entity or the second entity or the third entity.

[0116] In some embodiments, the first entity or the second entity or the third entity may obtain the first transmission time and the second transmission time; and determine the advance time based on the first transmission time and the second transmission time.

[0117] In some embodiments, the first signaling may include an advance time and a delay time. The target entity includes a first entity and a fourth entity.

[0118] In some embodiments, the first signaling including the advance time and the delay time is sent by the second entity or the third entity to the first entity and the fourth entity.

[0119] In some embodiments, the propagation time includes a third propagation time and a fourth propagation time; the third propagation time is a duration of signal propagation from the first entity to the second entity; the fourth propagation time is a 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, performing data transmission based on the first signaling includes at least one of the following:

[0120] The target entity includes a third entity, and when the third entity sends data, the data is sent after a delay based on the delay time;

[0121] The target entity includes a second entity, and when the second entity receives data, the processing window is advanced based on the advance time and the data is received based on the processing window.

[0122] It should be understood that when the third propagation time is greater than or equal to the fourth propagation time, it means that during the time window for receiving data sent by the first entity, the data received from the third entity by the second entity on the time domain resources may not form a complete time domain resource with the data from the first entity on the time domain resources. At this time, 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 to obtain the data from the first entity.

[0123] It should be understood that when the third entity sends data, the data is sent later based on the delay time, which can delay the time for the data from the third entity to arrive at 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 are complete in time domain resources, and ensuring that the second entity can correctly demodulate and obtain the data from the first entity.

[0124] For example, Figure 7As shown, it is a schematic diagram of another data transmission provided by an embodiment of the present disclosure, including: OFDM symbols sent by a third entity, OFDM symbols sent by a first entity; OFDM symbols received by a second entity from the first entity and the third entity. 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) 3 is the third propagation time, PT4 is the fourth propagation time, and the receiving processing window (processing window) is used to indicate the time window in which the second entity receives the OFDM symbol from the first entity. Combined with Figure 3 It can be seen that 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 from the third entity received by the second entity and the OFDM symbols from the first entity cannot form a complete OFDM symbol, and the orthogonality of the subcarriers on the OFDM symbols is destroyed. At this time, the second entity may not be able to accurately and reliably demodulate the signal.

[0125] For example, Figure 8 FIG. 1 is a schematic diagram of another data transmission provided by the present embodiment, for indicating Figure 7 In the third entity, based on the delay time ( Figure 8 DT) sends data when the first entity, the second entity, and the third entity perform data transmission. Figure 7 It can be seen that when the third entity sends data after a delay time, the second entity can completely receive the OFDM symbols of 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. In this way, the orthogonality of the subcarriers on the OFDM symbols can be guaranteed, thereby ensuring the reliability of communication.

[0126] It should be understood that the second entity receives data based on the advanced processing window, which can ensure that the second entity can completely receive the data from the third entity, and due to the existence of the cyclic prefix, the advanced processing window can still completely receive the data from the first entity. In this way, it can ensure that the data from both parties are complete in time domain resources, and can reduce 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.

[0127] For example, Fig. 9 FIG. 1 is a schematic diagram of another data transmission provided by the present embodiment, for indicating Figure 7 In the example, the second entity is based on the advance time ( Fig. 9AT) in advance receiving window, the first entity, the second entity and the third entity perform data transmission. Fig. 9 It can be seen that when the second entity advances the processing window based on the advance time, the second entity can completely receive the OFDM symbols from the third entity, and due to the existence of the cyclic prefix in the OFDM symbol from the first entity, the OFDM symbol of the first entity can still be completely received based on 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, and the reliability of communication is guaranteed.

[0128] It should be understood that when the third entity sends data, the data is sent after a delay time; and when the second entity receives data, the processing window is advanced based on the advance time and the data is received based on the processing window. This ensures that the data from both parties are complete in the time domain resources, and reduces the interference of 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.

[0129] For example, Fig.10 FIG. 1 is a schematic diagram of another data transmission provided by an embodiment of the present disclosure, for indicating Figure 7 The third entity delays sending data based on the delay time, and the second entity advances the data transmission of the processing window based on the advance time. Fig.10 It can be seen that the third entity delays sending data and the second entity raises 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 symbols can be guaranteed, and the reliability of communication is guaranteed.

[0131] It should be understood that the delay time is greater than or equal to the third time, which can ensure that after the third entity delays sending data, the time when the second entity receives the data from the third entity is later than or equal to the time when the data from the first entity is received, thereby ensuring 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 time domain resources.

[0132] It should be understood that the advance time is greater than or equal to the third time, which can ensure that the second entity can completely receive data from the third entity after the processing window is advanced, ensuring that the data from the first entity and the data from the third entity are complete in time domain resources.

[0133] In some embodiments, when the third propagation time is greater than or equal to the fourth propagation time, when the third entity sends data, the sending of the data is delayed based on the delay time; and when the second entity receives data, the processing window is advanced based on the advance time and the data is received based on the processing window. At this time, the sum of the delay time and the advance time is greater than or equal to the third time.

[0136] It should be understood that the delay time is greater than or equal to the third time and less than or equal to the fourth time, which can ensure that after the third entity delays sending data, the time when the second entity receives the data from the third entity is later than or equal to the time when the data from the first entity is received, thereby ensuring the integrity of the data received by the second entity from the third entity and ensuring that the data from the third entity is not too late, thereby ensuring that the data from the first entity and the data from the third entity are complete in time domain resources.

[0137] It should be understood that the advance time is greater than or equal to the third time and less than or equal to the fourth time, which can ensure that the second entity can completely receive the data from the third entity after the processing window is advanced, and ensure that the second entity does not receive the data from the first entity or the third entity too early, and ensure that the data from the first entity and the data from the third entity are complete in time domain resources.

[0138] It should be understood that the sum of the delayed time and the advanced time is greater than or equal to the third time and less than or equal to the fourth time, which can ensure that the time when the third entity sends data is not too late, and the time when the second entity receives data from the first entity or the third entity is not too early, ensuring that the data from the first entity and the data from the third entity are complete in time domain resources.

[0205] In some embodiments, the cyclic prefix in the data transmission may be an extended cyclic prefix (ECP).

[0206] In some embodiments, the resource configuration information is used to configure the position of the guard band and / or the size of the guard band.

[0207] It should be understood that due to frequency leakage or frequency offset, the devices of the environmental Internet of Things and the devices of the non-environmental Internet of Things may interfere with each other when using adjacent frequencies. At this time, 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, thereby ensuring that the frequency domain resources used by the devices of the environmental Internet of Things and the devices of the non-environmental Internet of Things are kept at a relatively far interval, thereby reducing mutual interference and improving the reliability of data transmission.

[0208] It should be understood that the larger the size of the guard band, the stronger the anti-interference capability of data transmission; and the smaller the size of the guard band, the more transmission resources can be used for data transmission.

[0209] In some embodiments, the frequency domain resource configuration information configures the position of the guard band, including at least one of the following:

[0210] Configuring the guard band to be located on the left side, the right side, or both sides of the first resource;

[0211] The guard band is configured to be located on the left side, the right side, or both sides of the second resource.

[0212] Among them, the first resource is a resource used by the environmental Internet of Things, and the second resource is a resource used by the non-environmental Internet of Things.

[0213] It should be understood that configuring the protection band to be located on the left side, right side, or both sides of the first resource, and / or configuring the protection band to be located on the left side, right side, or both sides of the second resource can isolate the resources used by the environmental Internet of Things from the resources used by the non-environmental Internet of Things, reduce mutual interference between the environmental Internet of Things and the non-environmental Internet of Things, and improve the reliability of data transmission.

[0214] In some embodiments, the position of the guard band may be determined based on the relative position of the first resource and the second resource.

[0215] In some embodiments, the first resource may be located to the left, to the right, or in the middle of the second resource.

[0216] Exemplarily, in the allocatable frequency domain resources, the first resource may be located on the left side of the second resource. In this case, a guard band may be configured on the right side of the first resource, or may be configured on the left side of the second resource.

[0218] Configure the number of resource elements (REs) included in the guard band;

[0219] Configure the number of resource blocks (RBs) included in the guard band.

[0221] In some embodiments, the minimum resource that can be used or allocated in the first resource is a resource unit, and the number of resource units and the size of the guard band can be configured in the first resource.

[0222] In some embodiments, the minimum resource that can be used or allocated by the second resource is a resource block, and the number of resource units and the size of the guard band can be configured in the second resource.

[0223] In some embodiments, resource units or resource blocks may be uniformly used in the first resource and the second resource to configure the guard band.

[0224] It should be understood that uniformly using resource units or resource blocks in the first resource and the second resource to configure the guard band can reduce the complexity of the guard band configuration and improve the efficiency of the guard band configuration.

[0225] In some embodiments, the number of resource units, the number of resource blocks, and the total number of resource units and resource blocks are greater than or equal to the target number.

[0226] In some embodiments, the target quantity may be zero.

[0227] In some embodiments, the data transmission satisfies one of the following:

[0228] A guard band is preconfigured in the first resource, and the guard band includes at least an integer multiple of resource units;

[0229] A guard band is preconfigured in the second resource, where the guard band includes at least an integer multiple of resource blocks;

[0230] A guard band is preconfigured in the first resource and the second resource, and the guard band includes at least an integer multiple of resource units and / or an integer multiple of resource blocks;

[0232] Among them, the first resource is a resource used by the environmental Internet of Things, and the second resource is a resource used by the non-environmental Internet of Things.

[0233] It should be understood that pre-configuring the conditions satisfied by the above data transmission is faster and simpler than configuring the protection band through signaling.

[0235] The receiving entity measures the target parameter within the protection band and feeds back the measurement result of the target parameter to the transmitting entity;

[0236] The transmitting entity adjusts the position and / or size of the guard band based on the measurement result of the target parameter.

[0237] It should be understood that the measurement result of the target parameter 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 result of the target parameter to meet the expected communication quality.

[0238] In some embodiments, resource configuration information, or the location and / or size of the guard band, is determined by:

[0239] The receiving entity measures the target parameters within the guard band;

[0240] The receiving entity determines and feeds back the expected guard band to the transmitting entity based on the measurement result of the target parameter;

[0241] The transmitting entity adjusts the position and / or size of the guard band based on the desired guard band.

[0242] It should be understood that the receiving entity directly determines the expected guard band, so that the transmitting entity can complete the adjustment of the guard band more quickly and conveniently.

[0243] In some embodiments, the target parameter includes 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).
