Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0002] Ambient Internet of Things (A-IoT) refers to IoT devices that obtain energy from the environment and then use this energy for wireless communication, so it can also be understood as a passive IoT. Traditional A-IoT technologies include RFID (Radio Frequency Identification). The basic principle of RFID is to use backscattering to complete energy conversion and communication. RFID systems generally include readers and radio frequency electronic tags. The reader sends electromagnetic waves of a certain frequency outward through its antenna; when the electronic tag enters the working range of the transmitting antenna, an induced current is generated inside it and it is activated, so the information stored in it is sent out through the internal antenna; the sending process is to load modulate the received electromagnetic waves; the antenna of the reader receives the carrier signal from the electronic tag and transmits it to the reader.

[0003] Traditional RFID has some drawbacks (such as short transmission distance), and the limited reading range of several meters usually requires hand-held scanning, which leads to labor-intensive and time-consuming operations, or RFID entrances / doors lead to expensive deployment. In addition, the lack of interference management schemes leads to serious interference and capacity issues between RFID readers, especially in dense deployment. These drawbacks make it difficult for RFID to support large-scale networks with seamless coverage.

[0004] In order to solve the defects of traditional passive devices, passive IoT based on cellular networks has been proposed and is in the process of standardization. Currently, 4 topologies are considered in the cellular passive IoT solution (such as Figures 1 to 5 As shown), wherein the third topology structure 3 further includes two topologies 3-1 and 3-2.

[0005] For topology 3-2, the base station triggers the A-IOT device (also known as a passive IoT terminal) to send data to the intermediate node, and the intermediate node forwards the received data to the base station. However, the prior art does not clarify the specific processing logic of the communicating parties. For example, it does not consider how the intermediate node should receive and forward the data of these A-IOT devices to the base station when the base station activates multiple types of A-IOT devices at one time. This is very likely to affect the device performance (for example, the power consumption of the intermediate node) and the communication effect. Summary of the invention

[0035] To solve the above technical problem, an embodiment of the present invention further provides a communication device, including a memory and a processor, wherein the memory stores a computer program that can be executed on the processor, and the processor executes the steps of the above method when running the computer program.

[0036] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0037] On the intermediate node side, an embodiment of the present invention provides a communication method, including: receiving control signaling, wherein the control signaling is used to indicate receiving data from a first device and / or sending data sent by a received first device; receiving data sent by at least one first device within a first time window, and / or sending the received data at a first time domain position.

[0038] Compared with the prior art, which does not clarify the specific processing logic of the communicating parties in the A-IOT scenario topology structure 3-2, this implementation scheme ensures that the intermediate node can correctly receive and / or upload the data sent by the first device (for example, A-IOT device) through control signaling, thereby improving communication reliability. Furthermore, by configuring the first time window, the intermediate node can clearly know the time when the A-IOT device is activated and sends data, avoiding the intermediate node from blindly receiving and wasting electricity. As a result, the power consumption of the intermediate node is reduced and the performance of the device is improved. Furthermore, by configuring the first time domain position, the resource allocation and timing relationship of the intermediate node forwarding A-IOT data to the base station are clarified, ensuring that the received data is transmitted to the base station in a timely and correct manner, improving communication reliability, and improving communication effects.

[0039] Furthermore, the number of the first devices is multiple, and the device types of the multiple first devices are at least partially different, and different first device types correspond to different receiving methods. Compared with the prior art that does not consider the specific processing logic of the intermediate node when the base station activates multiple types of A-IOT devices at one time, this implementation scheme enables the intermediate node to respectively receive the data sent by the corresponding A-IOT device according to the device type using an appropriate receiving method, thereby ensuring that the intermediate node can correctly receive the data of the A-IOT device of each device type when the base station activates multiple types of A-IOT devices at one time. Among them, the receiving action of the intermediate node can be triggered in response to the receipt of control signaling, or it can be performed periodically.

[0040] On the base station side, an embodiment of the present invention also provides a communication method, including: sending an activation instruction, wherein the activation instruction is used to activate a first device; sending a control signaling, wherein the control signaling is used to instruct the intermediate node to receive data sent by at least one first device within a first time window and / or send the received data sent by the first device at a first time domain position; and receiving the data sent by the intermediate node at the first time domain position.

[0041] Compared with the prior art, which only considers the information that needs to be indicated to the intermediate node when the base station activates a single first device, this embodiment ensures that the intermediate node can correctly receive and / or upload data sent by an unlimited number of first devices (e.g., A-IOT devices) through control signaling, thereby improving communication efficiency. Furthermore, by configuring the first time domain position, the resource allocation and timing relationship of the intermediate node forwarding A-IOT data to the base station are clarified, so that the base station can control the collection of data and improve the performance of the base station.

[0042] Furthermore, the number of the first devices is multiple, and the device types of the multiple first devices are at least partially different, and different device types of the first devices correspond to different receiving methods. Compared with the prior art that only considers the information that needs to be indicated to the intermediate node when the base station activates a single A-IOT device, this implementation scheme enables the intermediate node to receive the data sent by the corresponding A-IOT device in a suitable receiving method according to the device type through control signaling, ensuring that the base station can activate multiple types of A-IOT devices at one time, and correctly receive the data of A-IOT devices of different types through the intermediate node.

[0043] From the above, the implementation scheme can optimize the processing logic of the communicating parties in the topological structure of the auxiliary node configured in the environmental Internet of Things scenario, improve the equipment performance, and improve the communication effect.

[0053] As mentioned in the background technology, cellular passive IoT solutions currently consider four topologies: Topology 1, reference Figure 1 , the base station is directly connected to the A-IOT device, the A-IOT device sends data directly to the base station (also called A-IOT data, AmbientIoT data), and the base station sends signaling directly to the A-IOT device; topology 2, reference Figure 2 , the base station is connected to the A-IOT device through an intermediate node, where there is no direct connection between the base station and the A-IOT device; topology 3, reference Figure 3 and Figure 4 , the base station is connected to the A-IOT device through the intermediate node, and there is a connection between the base station and the A-IOT device; topology 4, reference Figure 5 , a terminal (eg, User Equipment (UE)) is directly connected to an A-IOT device. The connection method between the base station and the intermediate node may be, for example, a User to Network interface Universal (Uu).

[0054] The intermediate node in topology 2 has two-way transmission with the base station and the A-IOT device. In contrast, the intermediate node in topology 3 has one-way transmission with the base station and the A-IOT device, which helps to simplify the complexity and power consumption of the intermediate node. In this topology, the intermediate node can also be called an assisting node. In some embodiments, the intermediate node can be, for example, a repeater, a small base station, a terminal such as a mobile phone, etc.

[0055] For topology 3, there are two types:

[0056] 1) Topology 3-1, reference Figure 3, the base station instructs the intermediate node to activate the A-IOT device, the intermediate node activates the A-IOT device, and the A-IOT device sends data to the base station after being activated. The intermediate node in this topology is used to send activation information, configuration information, etc. After sending the aforementioned information to the A-IOT device, the intermediate node can feedback the information sending status to the base station.

[0057] 2) Topology 3-2, reference Figure 4 , the base station triggers the A-IOT device to send data, the data sent by the A-IOT device is received by the intermediate node, and the intermediate node forwards the received data of the A-IOT device to the base station. The intermediate node in this topology is used for data forwarding and / or amplification.

[0058] For A-IOT devices, three types of devices (also known as passive IoT terminal types based on cellular networks) have been basically determined at this stage, namely Type A, Type B and Type C. Among them, Type A is similar to RFID and completes communication through backscattering. Type A does not have energy storage capabilities and does not generate independent signals. Type B also completes communication based on backscattering. Similarly, Type B A-IOT devices do not generate independent signals. Unlike Type A, Type B A-IOT devices have energy storage capabilities, and the energy stored can be used to amplify the reflected signals. Type C has energy storage capabilities and independent signal generation, that is, it has active radio frequency components. In other words, Type A is a backscattering terminal without energy storage, Type B is a backscattering terminal with energy storage, and Type C is a terminal that actively sends signals with energy storage. Type C can be charged with radio frequency energy.

[0059] In summary, A-IOT devices of types A, B and C may have different modulation and coding methods. For example, type A / B uses amplitude shift keying (ASK) or frequency shift keying (FSK), while type C uses other higher-order modulation and coding methods (such as orthogonal frequency division multiplexing (OFDM)).

[0060] For topology 3-2, Chinese patent application 202111547386.4 discloses that the base station needs to provide at least one of the following information to the intermediate node so that the intermediate node can receive data from the A-IoT device: time domain resources, frequency domain resources, time window, precoding parameters, space-time code parameters, non-periodic transmission mode, period length information, time information of signal transmission within the transmission period, modulation method, coding method, delimiter, leading sequence synchronization information, frequency shift parameters, second terminal identifier, first terminal identifier, transmission identifier, total transmission duration. However, after analysis, the inventors of this application found that the prior art did not take into account the situation where the intermediate node needs to receive data transmitted by multiple A-IoT devices of different device types. This means that when the base station activates A-IOT devices of multiple device types at one time, the prior art will not be able to achieve this, affecting communication reliability and communication effect.

[0061] In addition, the prior art only considers how the base station triggers the intermediate node to receive data from the A-IOT device, but does not consider when the intermediate node should send the received data to the base station. This lack of consideration will result in the base station being unable to control the collection of data, affecting the communication effect. In addition, although the prior art conceptually mentions the first terminal identifier and the second terminal identifier, it does not further explain their specific uses, resulting in the intermediate node being unable to reasonably use all the parameters configured by the base station, affecting the performance of the intermediate node.

[0062] To solve at least one of the above-mentioned technical problems, this embodiment provides a communication method, including: receiving control signaling, wherein the control signaling is used to indicate receiving data from a first device and / or sending data sent by the received first device; receiving data sent by at least one first device within a first time window, and / or sending the received data at a first time domain position; wherein the first time domain position is located after the first time window.

[0063] By adopting this implementation scheme, control signaling is used to ensure that the intermediate node can correctly receive and / or upload data sent by the first device (for example, A-IOT device), thereby improving communication reliability. Furthermore, by configuring the first time window, the intermediate node can clearly know when the A-IOT device is activated and sends data, thereby avoiding the intermediate node from blindly receiving and wasting electricity. As a result, the power consumption of the intermediate node is reduced and the performance of the device is improved. Furthermore, by configuring the first time domain position, the resource allocation and timing relationship of the intermediate node forwarding A-IOT data to the base station are clarified, ensuring that the received data is transmitted to the base station in a timely and correct manner, improving communication reliability, and improving communication effects.

[0064] The base station in the embodiment of the present application may generally refer to a network device, which is a device that provides wireless communication functions for a user terminal, and may also be referred to as an access network device, a radio access network (RAN) device, or an access network element, etc. Among them, the network device may support at least one wireless communication technology, such as LTE, NR, etc. For example, the network device includes, but is not limited to: a next generation base station (generation nodeB, gNB) in the fifth generation mobile communication system (5th-generation, 5G), an evolved node B (evolved node B, eNB), a radio network controller (radio network controller, RNC), a node B (node ​​B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (for example, home evolved nodeB, or home node B, HNB), a baseband unit (baseband unit, BBU), a transmitting and receiving point (transmitting and receiving point, TRP), a transmitting point (transmitting point, TP), a mobile switching center, etc. The network device may also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario, or the access network device may be a relay station, an access point, a vehicle-mounted device, a terminal device, a wearable device, and a network device in future mobile communications or a network device in a future evolved PLMN. In some embodiments, the network device may also be a device having a wireless communication function for a user terminal, such as a chip system. For example, the chip system may include a chip and may also include other discrete devices.

It should be noted that the user terminal can support at least one wireless communication technology, such as Long Term Evolution (LTE for short), new radio (NR), etc. For example, the user terminal may be a mobile phone, a tablet computer (pad), a desktop computer, a laptop computer, an all-in-one computer, a vehicle-mounted terminal, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a wearable device, a terminal device in a future mobile communication network, or a terminal device in a future evolved public mobile land network (PLMN), etc. In some embodiments of the present application, the user terminal may also be a device with a transceiver function, such as a chip system, wherein the chip system may include a chip and may also include other discrete devices.

[0066] The intermediate node in the embodiment of the present application may include any of the aforementioned network devices, and may also include any of the aforementioned terminals.

[0067] The A-IOT devices of the embodiments of the present application may include the aforementioned type A, type B, and type C A-IOT devices.

[0068] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0069] Figure 6 It is a flow chart of a communication method according to the first embodiment of the present invention.

[0070] This implementation scheme can be applied to the A-IOT scenario (hereinafter referred to as the A-IOT scenario), and can be applied to the following scenarios: Figure 4 The topology structure of the auxiliary node shown is configured (for example, topology structure 3-2) for the application scenario of A-IOT communication.

[0071] In a specific implementation, the communication method provided in the following steps S601 to S602 may be executed by a chip with communication functions in the intermediate node, or may be executed by a baseband chip in the intermediate node.

[0072] Specifically, refer to Figure 6 The communication method described in this embodiment may include the following steps:

[0073] Step S601, receiving control signaling, wherein the control signaling is used to instruct receiving data from a first device and / or sending data received from a first device;

[0074] Step S602: receiving data sent by at least one first device within a first time window, and / or sending the received data at a first time domain position.

[0075] When the data sent by the first device is received and the received data is sent in step S602, the first time domain position is located after the first time window.

[0076] More specifically, the first device may include an A-IOT device.

[0077] In some embodiments, in step S601, the intermediate node may receive control signaling through a Uu port.

[0078] In some embodiments, the control signaling may be used to instruct reception of data of the first device. Accordingly, in step S602, the intermediate node receives data sent by at least one first device within the first time window.

[0079] Furthermore, the intermediate node may also send the data received in the first time window at the first time domain position.

[0080] In some embodiments, the control signaling may be used to indicate receiving data of the first device, and accordingly, in step S602, the intermediate node directly sends the periodically received data at the first time domain position. Specifically, the first time window may be a semi-statically configured periodic resource, the intermediate node periodically receives data, and sends the received data at the next first time domain position after receiving the control signaling.

[0081] In some embodiments, the control signaling may be used to indicate the sending of the received data sent by the first device, and accordingly, in step S602, the intermediate node sends the periodically received data at the first time domain position. Specifically, the first time window may be a semi-statically configured periodic resource, the intermediate node periodically receives the data, and sends the received data at the next first time domain position after receiving the control signaling.

[0082] Alternatively, in response to receiving the control signaling, the intermediate node may first receive data sent by at least one first device in a first time window, and then send the received data at a first time domain position.

[0083] Alternatively, in response to receiving the control signaling, the intermediate node may receive data sent by at least one first device in a first time window. Further, the first time window may be a semi-statically configured periodic resource, and the intermediate node periodically receives data and sends all data received in at least one first time window based on further instructions from the base station.

[0084] In some embodiments, the control signaling may be used to indicate receiving data from the first device and sending the received data sent by the first device. Accordingly, in step S602, the intermediate node may first receive data sent by at least one first device in the first time window, and then send the received data in the first time domain position.

[0085] Alternatively, the first time window may be a semi-statically configured periodic resource. Accordingly, in step S602, in response to receiving the control signaling, the intermediate node may directly send all periodically received data at the next first time domain position.

[0086] Alternatively, the first time window may be a semi-statically configured periodic resource. In step S602, in response to receiving the control signaling, the intermediate node periodically receives data and processes the data (e.g., modulates, encodes, packages, etc.). The processed data packets wait for further instructions from the base station to be sent.

[0087] In a specific implementation, if there are multiple first devices, and the device types of the multiple first devices are at least partially different, the corresponding receiving mode can be determined according to the device type.

[0088] Specifically, the device types of the multiple first devices being at least partially different may mean that the device types of the multiple first devices include multiple device types. For example, the intermediate node receives data sent by three first devices within the first time window, and the device types of the three first devices are type A, type B, and type C, respectively.

[0089] In some embodiments, different device types of the first device correspond to different receiving modes. That is, different receiving modes are configured for each device type. For example, the receiving mode corresponding to type A may be an FSK encoding mode. For another example, the receiving mode corresponding to type C may be an OFDM encoding mode.

[0090] In some embodiments, different device types may correspond to the same receiving mode. For example, the receiving modes corresponding to types A and B may both be FSK encoding modes.

[0091] In a specific implementation, the control signaling may include at least one of the following parameters: a receiving mode, a receiving frequency, a device type of the first device, an identifier of the first device, the number of first devices, a first time window, a first time domain position, and a sending mode.

[0092] Specifically, the information included in the control signaling may include device information of the first device, which is used to describe the characteristics of the first device itself, such as the device type of the first device, the identifier of the first device, etc.

[0093] The device identifier may be used to uniquely identify the first device. In some embodiments, if there are multiple first devices around the intermediate node, the intermediate node may selectively receive data sent by the first device identified in the control signaling.

[0094] The device type may include type A, type B, and type C. Further, the device type may be further subdivided into type A, type B under the first working mode, type C under the second working mode, type B under the third working mode, and type C under the fourth working mode. Among them, the first and second working modes are low power modes, and the third and fourth working modes are high power modes. In some embodiments, if there are first devices of multiple device types around the intermediate node, the intermediate node may selectively receive data sent by the first device of the device type indicated in the control signaling.

[0095] Furthermore, the control signaling may also include the number of first devices. Accordingly, the intermediate node may accurately know the number of first devices that need to receive data this time.

[0096] Furthermore, the information included in the control signaling may include data transmission information of the first device, which is used to describe the transmission information when the first device receives / sends A-IOT data / signaling, for example, receiving mode, receiving frequency, etc.

[0097] The receiving mode may include a coding mode, and the coding mode may be a modulation coding mode for receiving and sending data / signals by the first device, and may specifically include a first mode and / or a second mode, wherein the first mode may be, for example, an ASK mode, and the second mode may be, for example, an OFDM mode. Through the indicated coding mode, the intermediate node may determine the device type of the first device.

[0098] The receiving mode may also include a carrier and a time unit. For example, the control signaling may indicate a plurality of coding modes, wherein at least a portion of the coding modes may be in different carriers or in different time units. The time unit may be a communication granularity in the time domain between a terminal device (e.g., a first device, an intermediate node) and a network device (e.g., a base station). For example, the time unit may be a time slot, a mini-time slot (i.e., a time unit shorter than a time slot), a subframe, a symbol, a frame, etc.

[0099] The receiving frequency may be a frequency at which the intermediate node receives data sent by the first device, corresponding to a downlink carrier of the first device.

[0100] The receiving mode and the receiving frequency may correspond to each other, and the specific corresponding mode may include: the receiving frequency corresponding to at least one receiving mode is different from the receiving frequency corresponding to other receiving modes. For example, the control signaling may indicate one or more receiving frequencies, and the receiving modes of different receiving frequencies are the same or different.

[0101] Further, the information contained in the control signaling may also include a receiving window (which may be a receiving time or a time window) for the intermediate node to receive data, such as a first time window. The first time window may be spaced apart from the time unit where the control signaling is located by a first duration (denoted as delay1), and the control signaling may include the first duration to indirectly indicate the first time window. The intermediate node begins to receive data sent by at least one first device after the first duration has elapsed since the control signaling was received. The unit of the first duration may be a time unit. In some embodiments, if the time unit of the first duration is a time slot, the value of the first duration may be zero.

[0102] Further, the starting time domain position of the first time window is no later than the earliest sending time domain position of at least one first device indicated by the control signaling. That is, the first time window at least covers the second time window, wherein the second time window is the sending time window of at least one first device. Among them, the sending time window of at least one first device may refer to the total interval length of the sending time windows of all first devices in the at least one first device in the time domain.

[0103] Furthermore, the information included in the control signaling may also include the feedback time of the intermediate node feeding back the received data to the base station, such as the first time domain position. For example, the control signaling may include a second duration (denoted as delay2), and the first time domain position is at least the length of the first duration plus the second duration from the time interval of receiving the control signaling. Accordingly, the intermediate node starts to send the received data to the base station at least after the first duration plus the second duration has passed since receiving the control signaling.

[0104] Furthermore, the information contained in the control signaling may also include a feedback method for the intermediate node to send the received data to the base station, such as a sending method. In some embodiments, the sending method may include sending frequency domain resources and a coding method used by the intermediate node to send data. For example, the intermediate node may use A-IOT resources and feedback the received data in coding method 1. For another example, the intermediate node may use NR air interface resources and use a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH for short) as a bearer to send the received data to the base station.

[0105] In some embodiments, if the control signaling includes the above-mentioned parameters of multiple first devices (for example, receiving mode, receiving frequency, device type of the first device, identification of the first device, number of first devices, first time window, first time domain position and / or sending mode), each first device can be configured with a set of parameters accordingly.

[0106] Alternatively, at least a portion of the plurality of first devices may be indicated with the same set of parameters.

[0107] In a specific implementation, the control signaling may be carried by dynamic control signaling. For example, at least a portion of the control signaling may be carried by downlink control information (DCI). For another example, at least a portion of the control signaling may be carried by a physical downlink shared channel (PDSCH).

[0108] In some embodiments, if the contents of the control signaling are all carried in the DCI, the time unit where the control signaling is located is the time unit where the DCI is located. Accordingly, the intermediate node starts to receive the data sent by the first device n time slots / symbols / microseconds after the time slot where the DCI is located. Where n is the first time length.

[0109] In some embodiments, if at least a portion of the control signaling is carried on the PDSCH, the time unit where the control signaling is located is the time unit where the end domain position of the PDSCH is located. Accordingly, the intermediate node starts receiving the data sent by the first device n time slots / symbols / microseconds after the end slot of the PDSCH. Where n is the first time length.

[0110] For example, if the number of identifiers of the first device contained in the control signaling is large, resulting in a large amount of data, all or part of the control signaling can be carried by PDSCH. In this example, DCI needs to indicate whether the intermediate node needs to decode PDSCH to obtain the control information. Further, if the control signaling is carried by PDSCH, the first time window is after the first duration after the end position of PDSCH. In other words, the first duration indicated in the DCI determines its different start times depending on whether there is PDSCH scheduling.

[0111] In a variation, the control signaling may be carried by semi-static scheduling information. For example, all parameters in the control signaling may be configured semi-statically, and the base station receives the A-IOT data sent by the first device from the intermediate node once every 10 ms.

[0112] In one variation, the control signaling may be carried jointly by dynamic control signaling and semi-static scheduling information. For example, the first time domain position may be semi-statically configured as a periodic resource by RRC signaling, and in response to receiving the control signaling, the intermediate node sends the received data at the next nearest first time domain position.

[0113] In a specific implementation, the first time domain position and the end time domain position of the first time window may be separated by a second time length, and the second time length is not less than the first preset time length. The specific value of the first preset time length may be determined according to the time length required for the intermediate node to process the received data.

[0114] Specifically, the encoding method of the first device to send data may be different from the sending method of the intermediate node to send data. Then the intermediate node needs to modulate the received data, such as modulating to OFDM encoding method. Furthermore, the intermediate node also needs to package and scramble the received data within the second time length.

[0115] In a specific implementation, in step S602, receiving data sent by at least one first device within the first time window may include: receiving data sent by at least one first device indicated by the control signaling within the first time window.

[0116] Specifically, the base station can selectively indicate the identifier of the first device that needs to be fed back by the intermediate node through control signaling. Accordingly, for each identifier of the first device indicated by the control signaling, the intermediate node receives data sent by the first device uniquely identified by the identifier.

[0117] In one variation, in step S602, receiving data sent by at least one first device within the first time window may include: selecting one or more first devices from at least one first device indicated by the control signaling and receiving data sent by the one or more first devices within the first time window.

[0118] Specifically, the intermediate node can autonomously select the first device to be actually received. For example, the base station can indicate the identifiers of five first devices through control signaling, and the intermediate node selects three first devices from them to receive data. In this way, the performance of the intermediate node can be improved.

[0119] Furthermore, if the intermediate node autonomously selects the first device for actual reception, when sending data to the base station, it may also report the identifier of the specific first device for reception so that the base station can synchronize the data reception status.

[0120] In a specific implementation, in step S602, sending the received data at the first time domain location may include: sending the received data at the first time domain location and / or an identifier of the first device that sends the data.

[0121] In the A-IOT-based cargo inventory application scenario, each cargo has a corresponding A-IOT device, for example, each cargo is affixed with a corresponding A-IOT label. The base station activates at least one A-IOT device in the warehouse, and after the intermediate node receives the data sent by the A-IOT device (including at least the identification of the A-IOT device), it reports the received identification to the base station. Thus, the base station can complete the cargo inventory according to the identification received from the intermediate node.

[0122] In some embodiments, the A-IOT device continuously collects environmental information and uploads data and its own identification when activated. For the intermediate node, it can choose to report data, identification or both.

[0123] In some embodiments, for low-end A-IOT devices, data and identification are sent by default when triggered, and the intermediate node decides whether to send data, identification or both to the intermediate node.

[0124] In some embodiments, the base station can trigger the specific content that the high-end A-IOT device needs to send, and the intermediate node only performs forwarding operations and does not filter the sent content.

[0125] From the above, on the intermediate node side, control signaling is used to ensure that the intermediate node can correctly receive and / or upload data sent by the first device (for example, A-IOT device), thereby improving communication reliability. Further, by configuring the first time window, the intermediate node can clearly identify the time when the A-IOT device is activated and sends data, thereby avoiding the intermediate node from blindly receiving and wasting electricity. As a result, the power consumption of the intermediate node is reduced and the performance of the device is improved. Furthermore, by configuring the first time domain position, the resource allocation and timing relationship of the intermediate node forwarding A-IOT data to the base station are clarified, ensuring that the received data is transmitted to the base station in a timely and correct manner, improving communication reliability, and improving communication effects.

[0126] Furthermore, by enabling the intermediate node to respectively receive the data sent by the corresponding A-IOT device using an appropriate receiving method according to the device type, it is ensured that when the base station activates multiple types of A-IOT devices at one time, the intermediate node can correctly receive the data of the A-IOT devices of each device type. The receiving action of the intermediate node can be triggered in response to receiving a control signaling, or it can be executed periodically.

[0132] This implementation scheme can be applied to A-IOT scenarios, and can be applied to the following scenarios: Figure 4 The topology structure 3-2 shown is an application scenario for A-IOT communication.

[0133] In a specific implementation, the communication method provided in the following steps S801 to S803 may be executed by a chip with communication functions in the base station, or may be executed by a baseband chip in the base station.

[0134] Specifically, refer to Figure 8 The communication method described in this embodiment may include the following steps:

[0135] Step S801, sending an activation instruction, wherein the activation instruction is used to activate the first device;

[0136] Step S802: Send control signaling, wherein the control signaling is used to instruct the intermediate node to receive data sent by at least one first device within a first time window and / or to send the received data sent by the first device at a first time domain position, and the first time domain position is located after the first time window;

[0137] Step S803: receiving data sent by the intermediate node at the first time domain location.

[0138] Those skilled in the art will appreciate that step S802 and step S803 may be considered as similar to the above Figure 6 The step S601 and step S602 of the embodiment shown in the figure are corresponding execution steps, and the two complement each other in specific implementation principles and logic. Figure 6 The relevant description of the illustrated embodiment will not be repeated here.

[0139] In some embodiments, in step S801, an activation instruction may be sent to one or more first devices. Specifically, a single activation instruction may activate one first device, or may activate multiple first devices at one time.

[0140] In some embodiments, step S801 and step S802 may be executed synchronously or asynchronously. When executed asynchronously, the order of execution of the two may be interchangeable.

[0141] In a specific implementation, if there are multiple first devices, and the device types of the multiple first devices are at least partially different, different device types of the first devices correspond to different receiving modes.

[0142] In a specific implementation, the control signaling includes at least one of the following parameters: a receiving mode, a receiving frequency, a device type of the first device, an identifier of the first device, the number of first devices, a first time window, a first time domain position, and a sending mode.

[0143] In a specific implementation, the receiving mode and the receiving frequency point correspond to each other, and the corresponding mode includes: the receiving frequency point corresponding to at least one receiving mode is different from the receiving frequency points corresponding to other receiving modes.

[0144] In a specific implementation, step S803 may include: receiving, at the first time domain location, data sent by the intermediate node and / or an identifier of a first device that sends the data.

[0145] In a specific implementation, the first time window and the time unit where the control signaling is located are separated by a first duration, and the starting time domain position of the first time window is no later than the earliest sending time domain position of the at least one first device.

[0146] In a specific implementation, if the control signaling is carried in downlink control information, the time unit where the control signaling is located is the time unit where the downlink control information is located; if at least part of the control signaling is carried in a physical downlink shared channel, the time unit where the control signaling is located is the time unit where the end domain position of the physical downlink shared channel is located.

[0147] In a specific implementation, the first time domain position and the end time domain position of the first time window are separated by a second time length, and the second time length is not less than a first preset time length.

[0148] In a specific implementation, the first time window at least covers a second time window, wherein the second time window is a sending time window of the at least one first device.

[0149] In a specific implementation, the control signaling is carried by dynamic control signaling and / or semi-static scheduling information.

[0150] In a specific implementation, the first device includes an A-IOT device.

[0151] From the above, on the base station side, control signaling is used to ensure that the intermediate node can correctly receive and / or upload data sent by an unlimited number of first devices (e.g., A-IOT devices), thereby improving communication efficiency. Furthermore, by configuring the first time domain position, the resource allocation and timing relationship of the intermediate node forwarding A-IOT data to the base station are clarified, so that the base station can control data collection and improve base station performance.

[0152] Furthermore, control signaling enables the intermediate nodes to use appropriate receiving methods according to the device types to receive data sent by the corresponding A-IOT devices, ensuring that the base station can activate A-IOT devices of multiple types at one time and correctly receive data from A-IOT devices of different types through the intermediate nodes.

[0153] Fig. 9 FIG. 9 is a schematic diagram of the structure of a communication device 9 according to a fourth embodiment of the present invention. A person skilled in the art will appreciate that the communication device 9 described in this embodiment can be used to implement the above Figure 8 The method and technical solution described in the embodiments.

[0154] Specifically, refer to Fig. 9 The communication device 9 described in this embodiment may include: a first sending module 91, used to send an activation instruction, wherein the activation instruction is used to activate the first device; a second sending module 92, used to send control signaling, wherein the control signaling is used to instruct the intermediate node to receive data sent by at least one first device within a first time window and / or to send the received data sent by the first device at a first time domain position, and the first time domain position is located after the first time window; a receiving module 93, used to receive the data sent by the intermediate node at the first time domain position.

[0155] For more information about the working principle and working mode of the communication device 9, please refer to the above Figure 8 The relevant description in will not be repeated here.

[0156] In a specific implementation, the above-mentioned communication device 9 can correspond to a chip with communication function in a base station, or to a chip with data processing function, such as a system-on-a-chip (SOC for short), a baseband chip, etc.; or to a chip module in a base station that includes a chip with communication function; or to a chip module with a chip with data processing function, or to a base station.

[0157] In a specific implementation, each module / unit included in each device or product described in the above embodiments may be a software module / unit or a hardware module / unit, or may be partly a software module / unit and partly a hardware module / unit.

[0158] For example, for each device or product applied to or integrated in a chip, each module / unit contained therein may be implemented in the form of hardware such as circuits, or at least some of the modules / units may be implemented in the form of software programs, which run on a processor integrated inside the chip, and the remaining (if any) modules / units may be implemented in the form of hardware such as circuits; for each device or product applied to or integrated in a chip module, each module / unit contained therein may be implemented in the form of hardware such as circuits, and different modules / units may be located in the same component (such as a chip, circuit module, etc.) or different components of the chip module, or at least some of the modules / units may be implemented in the form of software programs. The element can be implemented in the form of a software program, which runs on a processor integrated inside the chip module, and the remaining (if any) modules / units can be implemented in the form of hardware such as circuits; for various devices and products applied to or integrated in the terminal, the various modules / units contained therein can be implemented in the form of hardware such as circuits, and different modules / units can be located in the same component (for example, chip, circuit module, etc.) or in different components in the terminal, or, at least some modules / units can be implemented in the form of a software program, which runs on a processor integrated inside the terminal, and the remaining (if any) modules / units can be implemented in the form of hardware such as circuits.

[0159] In a typical application scenario, refer to Fig.10 , the base station sends an activation instruction at time t1 to activate the A-IoT device. The A-IoT device reads the activation instruction from the base station and sends data (e.g., A-IoT data) in the second time window starting from time t3 after the processing time specified by the A-IoT device (e.g., 150 microseconds after the EOF (end of frame) of RFID).

[0160] Between time t1 and time t3, at least one activated A-IOT device receives a carrier signal in a first manner at its respective operating frequency for charging, and / or receives and decodes an activation instruction.

[0161] On the other hand, the base station sends a control signaling to the intermediate node at time t2 to instruct the intermediate node to start receiving the data sent by the A-IoT device at time t3 after the first time duration (which may be the number of time slots representing the length of the first time duration, or may be the absolute time point representing the starting time domain position of the first time window).

[0162] The end position of the indicated first duration is no later than the earliest sending position of at least one activated A-IoT device. In other words, the first duration is used to ensure that the first time window and the second time window are aligned at time t3.

[0163] In some embodiments, the second time window may be determined or indicated by a protocol.The second time window may be contained by the first time window of the intermediate node.

[0164] Furthermore, the second time window may include the interaction and handshake process between the intermediate node and the A-IoT device.

[0165] Furthermore, the intermediate node starts to send the data received in the first time window to the base station after a second time period (for example, time t5) after the end position of the second time window. Accordingly, time t5 may correspond to the first time domain position.

[0166] In some embodiments, the intermediate node prepares uplink data within the second time period from time t4 to time t5, which may include modulating the data of the A-IOT device received in the first time window into a coding method (such as OFDM coding method) that can be processed by the base station, and may also include data packaging, scrambling, etc.

[0167] In some embodiments, time t2 may be before time t1 in the time domain.

[0168] In a typical application scenario, it is assumed that the control signaling indicates that the transmission mode is PUSCH resource carrying or transmission via the Uu interface, and data of one (for example, a single device type) A-IoT device is received. Fig.10 and Fig.11 , the intermediate node receives DCI on the downlink carrier of the Uu port at time slot n (corresponding to time t2), and the control signaling carried in the DCI instructs the intermediate node to start receiving A-IoT data on A-IoT carrier X in coding mode 1 at time slot n+m (corresponding to time t3). Furthermore, the control signaling also indicates that after the first time window (e.g., z time slots from time slot n+m), the received data is sent to the base station on the uplink carrier of the Uu port at an interval of p time slots (corresponding to time t5).

[0169] Furthermore, the sending position (for example, the first time domain position) of the uplink resource for sending data from the intermediate node to the base station may also be indicated by the DCI. The sending frequency domain resource of the uplink resource may be an NR resource or an A-IoT resource, corresponding to different coding methods. Fig.11 The example of sending on NR resources is used for exemplary demonstration. In this example, the intermediate node uses NR physical resource blocks combined with OFDM to send data.

[0170] In a typical application scenario, assume that the control signaling indicates that the sending mode is A-IoT resource bearer, and receives data from multiple A-IoT devices, which can be encoded using different encoding types. Fig.10 and Fig.12, the intermediate node receives DCI on the downlink carrier of the Uu port at time slot n (corresponding to time t2), and the control signaling carried in the DCI instructs the intermediate node to receive data sent by multiple A-IOT devices in the downlink carrier X and / or Y of the A-IoT device in time slot n+m (corresponding to time t3) in coding mode 1 and / or 2. For example, data sent by A-IOT devices of type A / B can be received in coding mode 1 on the downlink carrier X of the A-IoT device. For another example, data sent by A-IOT devices of type C can be received in coding mode 2 on the downlink carrier Y of the A-IoT device.

[0171] Furthermore, after the first time window (eg, z time slots have passed since time slot n+m), the received data is sent to the base station on the uplink carrier of the Uu port at intervals of p time slots (corresponding to time t5).

[0172] Furthermore, the sending position (for example, the first time domain position) of the uplink resource through which the intermediate node sends data to the base station may be indicated by the DCI. Fig.12 The example of sending on A-IoT resources is used for exemplary demonstration. In this example, the intermediate node uses the uplink carrier of the A-IoT device combined with FSK and other encoding methods to send data.

[0173] In a typical application scenario, it is assumed that at least part of the control signaling is carried by PDSCH, for example, PDSCH carries the identifier of the first device that needs to receive data. Specifically, a new bit can be added to the DCI to indicate whether the control signaling for A-IOT data reception involves PDSCH. If the new bit indicates that part or all of the control signaling needs to be obtained based on PDSCH, the first duration is calculated based on the end time of the PDSCH time slot (e.g. Fig.13 ), otherwise it is calculated based on the end time of DCI (as shown in Fig.11 and Fig.12 shown).

[0174] refer to Fig.10 and Fig.13 , the intermediate node receives DCI on the downlink carrier of the Uu port at time slot n (corresponding to time t2), and the control signaling carried in the DCI indicates that PDSCH needs to be decoded. Correspondingly, the intermediate node receives PDSCH at the time slot n+m, and receives A-IoT data in coding mode 1 and / or 2 on the downlink carrier X and / or Y of the A-IoT device at time slot n+m+m' (corresponding to time t3).

[0175] Furthermore, after the first time window (eg, z time slots have passed since time slot n+m+m'), the received data is sent to the base station on the uplink carrier of the Uu port at intervals of p time slots (corresponding to time t5).

[0176] Furthermore, the sending position (for example, the first time domain position) of the uplink resource through which the intermediate node sends data to the base station may be indicated by the DCI. Fig.13 The example of sending on A-IoT resources is used for exemplary demonstration. In this example, the intermediate node uses the uplink carrier of the A-IoT device combined with FSK and other encoding methods to send data.

[0177] The embodiment of the present invention further provides a computer-readable storage medium, which is a non-volatile storage medium or a non-transitory storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the communication method provided in any of the above embodiments are executed.
