Description

Method and wireless communication device for wireless communication TECHNICAL FIELD

[0001] The present disclosure relates to the field of wireless communication, and in particular, to a method and wireless communication device for wireless communication. BACKGROUND

[0002] In recent years, Internet of Things (IoT) has attracted much attention in the field of wireless communication. With the continuous development of communication systems, IoT terminals will be applied to various application scenarios, including home, industry, agriculture, medical care and other fields. In order to be able to deploy IoT terminals on a large scale in various application scenarios, it is crucial to reduce the size, complexity and power consumption of IoT terminals. Traditional IoT devices, such as NB-IoT terminals, MTC terminals and RedCap terminals, all have batteries and need to be replaced regularly or charged. With the large-scale increase in the number of future IoT terminals, the use of existing IoT systems will greatly increase the cost of power supply and labor. In addition, traditional IoT terminals are not suitable for extreme environments, such as high temperature and high pressure environments. Ambient IoT (AIoT) devices mainly use external environments (such as light, radio waves, motion, heat energy, etc.) to obtain energy, so they do not need battery devices or only have low power storage capacity (such as capacitors), and do not need to manually replace batteries or charge, which can effectively avoid the problems of existing IoT systems. Compared with existing NB-IoT, MTC and RedCap terminals, AIoT devices have lower complexity, lower power consumption and lower cost, for example, the power consumption of NB-IoT is in the order of milliwatts, while the power consumption of AIoT devices is in the order of microwatts.

[0003] At present, the academic and industrial circles have shown strong research interest in AIoT devices, and have carried out in-depth research around modulation, coding, interference cancellation, multiple access, channel modeling and estimation, etc. In general, for AIoT devices, research and improvement are needed around physical layer key technologies, resources and scheduling, system optimization. Therefore, it is necessary to propose a method and wireless communication device for ambient Internet of Things special wireless communication to improve the prior art.

[0024] The technical matters, structural features, implementation purposes and effects of the embodiments of the present disclosure are described in detail with reference to the drawings as described below. Specifically, the terms in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not limiting the present disclosure.

[0025] In the present disclosure, "A or B" can mean "A only", "B only", or "both A and B".

[0026] In other words, in the present disclosure, "A or B" can be interpreted as "A and / or B". For example, in the present disclosure, "A, B, or C" can mean "A only", "B only", "C only", or "any combination of A, B, C".

[0027] The slash ( / ) or comma used in the present disclosure can mean "and / or". For example, "A / B" can mean "A and / or B". Therefore, "A / B" can mean "A only", "B only", or "both A and B". For example, "A, B, C" can mean "A, B, or C".

[0028] In the disclosure, "at least one of A and B" can mean "only A", "only B", or "both A and B". In addition, in the disclosure, the expression "at least one of A or B" or "at least one of A and / or B" can be interpreted as "at least one of A and B".

[0029] In addition, in the disclosure, "at least one of A, B, and C" can mean "only A", "only B", "only C", or "any combination of A, B, and C". In addition, "at least one of A, B, or C" or "at least one of A, B, and / or C" can mean "at least one of A, B, and C".

[0030] Furthermore, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or an implied indication of the number of indicated technical features. Thus, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0031] Those skilled in the art will recognize and appreciate that the details of the described examples are merely illustrative of some embodiments and that the teachings set forth herein are applicable to a wide variety of alternative arrangements.

[0032] The technical solutions of the present disclosure can be applied to various wireless communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, 5G communication system or future wireless communication system, etc.

[0033] The technical solutions of the present disclosure can also be applied to the system of Ambient Internet of Things (AIOT). There are four kinds of system topology architecture of Ambient Internet of Things (AIOT), and the system topology architecture of the present disclosure can be topology 2, as shown in FIG. 1. In addition, the types of Ambient Internet of Things devices are device1, device2a, and device2b, respectively, and are described as follows:

[0034] -device1: Cellular evolution of traditional RFID passive tag, with the lowest power consumption and the simplest device structure;

[0035] -device2a: Performance enhancement and cellular evolution of traditional RFID tag, also known as semi-passive tag, with greater power consumption and more complex hardware devices than device1;

[0036] - device2b: an evolved version of NB-IoT with lower power consumption, lower hardware complexity. 2b can generate the CW autonomously since it does not need an external CW, thus it has the highest hardware complexity and power consumption.

[0037] In this disclosure, the node directly connected with the AIoT device is "Reader", and the logical entity of the related operation can be based on the base station, or based on the user equipment. In topology 2, the user equipment (UE) is connected with the AIoT device and performs the operation related to the environmental Internet of Things business, and the UE can be referred to as a user equipment reader (UE reader). Here, the UE can be a normal UE, an IAB node, a relay node, a repeater, etc.

[0038] The information sending method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0039] In the conventional small data transmission mechanism (SDT), that is, the UE in the RRC_INACTIVE state can still perform data / signaling message transmission, which means that the UE can perform data and signaling transmission without switching to the RRC_CONNECTED state, so it can be seen that the introduction of the SDT mechanism can reduce the signaling overhead on the one hand and reduce the power consumption of the device on the other hand. Further, considering that the network side configures the NR SDT resource on the initial BWP, therefore, the NR SDT configuration is UE level, that is, the NR SDT configuration contains the UE-specific NR SDT resource. For example, the preconfigured SDT resource is configured in the RRCRRelease with suspend indication, at this time, the CG resource for SDT is only valid in the PCell of the UE.

[0040] In the AIoT system, for the UE reader, it usually manages multiple AIoT devices, and the AIoT device sends data randomly, and the UE reader cannot determine when the environmental Internet of Things data or signaling will be received. Therefore, if the UE is always in the RRC_Connected state to send the AIoT device business data packet, the power consumption of the UE reader will be greatly increased, on the other hand, the data volume of the environmental Internet of Things business is usually small. Therefore, the UE in the RRC_inactive state can act as a UE reader and can support the transmission of AIoT device data or signaling, and this mechanism is called AIoT SDT mechanism.

[0041] However, considering the current tense situation of spectrum effect, the environmental Internet of Things business performed by the UE reader is not always on, and the location of the UE reader is controllable. Therefore, for the AIoT SDT mechanism, a scheme for configuring shared resources on the wireless cellular network air interface for carrying small data transmission of environmental Internet of Things is proposed. Further, unlike the UE-level SDT resources of the traditional technology, each UE reader can be configured with shared resources on the wireless cellular network air interface for carrying small data transmission of environmental Internet of Things, and multiple UE readers can reuse the same block of resources to achieve the effect of saving resources. Further, the network side divides the AIoT SDT shared resources into multiple shared resources with finer granularity, so that the UE reader selects one (or multiple) suitable shared resource from the multiple sets of shared resource information for transmitting AIoT data or signaling. By grouping the shared resources, on the one hand, the utilization rate of AIoT shared resources is improved, on the other hand, the interference between UE readers can be reduced, and to some extent, the resource conflict can be reduced. Here, the resource is a shared resource on the cellular air interface for transmitting environmental Internet of Things related data or signaling.

[0042] In another scenario, as shown in FIG. 1, in topology 2 (topology 2 is prior art, which will not be described here), the UE reader can obtain shared resources through pre-configuration, or RRC, or system message, and the shared resources can be used on the AIoT-Uu air interface for transmitting signaling or data between the second device 120 and the UE reader. Here, the resource is a shared resource on the environmental Internet of Things air interface for transmitting environmental Internet of Things related data or signaling. Similar to AIoT SDT, the UE reader can manage different AIoT devices or perform different business operations at different times, and how to select a more suitable AIoT-Uu shared resource from multiple shared resources on the environmental Internet of Things air interface for transmitting environmental Internet of Things related data or signaling.

[0043] To solve the above problems, the present disclosure provides a method of wireless communication to solve the above problems.

[0044] FIG. 2 illustrates one of the flowcharts of the method of wireless communication provided by the present disclosure, as shown in FIG. 2, the method can be applied to the first device 110 (the first device 110 can be a UE reader or a UE, as shown in FIG. 1). The method comprises:

[0045] Step S10, the first device acquires or receives the first information of the third device, wherein the first information is resource indication information and / or configuration information for transmitting environmental Internet of Things related data or signaling;

[0046] Step S20, selecting resources for transmitting the data or signaling related to the Internet of Things based on the first information, and / or transmitting the data or signaling related to the Internet of Things.

[0047] In particular, the third device 130 can be a base station or a core network element, and the resource is used to perform ambient Internet of Things (AIoT) service, i.e., is dedicated to transmitting data or signaling related to the ambient Internet of Things (AIoT), and can also be regarded as an ambient Internet of Things (AIoT) dedicated resource. The resource can be a shared resource or a resource at the first device 110 level; the shared resource can be a cell-level resource or a region-level resource. The (shared) resource can be a (shared) resource on a wireless cellular network air interface used to carry ambient Internet of Things (AIoT) small data transmission (AIoT SDT), and / or a (shared) resource on an ambient Internet of Things (AIoT) air interface (AIoT-Uu) used to transmit data or signaling related to the ambient Internet of Things. It is worth noting that the resource on the wireless cellular network air interface used to carry ambient Internet of Things (AIoT) small data transmission is configured on the Uu air interface, and is resource information used by the first device 110 when transmitting ambient Internet of Things (AIoT) service; the resource on the ambient Internet of Things (AIoT) air interface used to transmit data or signaling related to the ambient Internet of Things is configured on the AIoT-Uu air interface, and is resource information used by the second device 120 (which can be an AIoT device, as shown in FIG. 1) and / or the first device 110 when transmitting data or signaling related to the ambient Internet of Things. The network side configures or predefines the resource suitable for AIoT-Uu for the first device 110. For the shared resource on the ambient Internet of Things (AIoT) air interface used to transmit data or signaling related to the ambient Internet of Things, on the one hand, for the second device 120, it can be ensured that there is a resource between the second device 120 and the first device 110, and the transmission of the ambient Internet of Things (AIoT) message on the AIoT-Uu air interface is ensured. In particular in the scenario where the first device 110 and the second device 120 are directly connected, the transmission can be ensured by the configured or predefined resource; on the other hand, for the first device 110, the predefined resource information can reduce the signaling overhead, i.e., the first device 110 does not need to allocate resources for the ambient Internet of Things (AIoT) to enter the connection request state. For the shared resource on the ambient Internet of Things (AIoT) air interface used to transmit data or signaling related to the ambient Internet of Things, the third device 130 configures or predefines the shared resource on the ambient Internet of Things (AIoT) air interface used to transmit data or signaling related to the ambient Internet of Things for the first device 110, which can ensure that the first device 110 does not need to enter the connection state from the inactive state, but can directly forward or transmit the data and signaling of the AIoT, thereby reducing the power consumption and signaling overhead of the first device 110. Further, whether it is the shared resource on the ambient Internet of Things (AIoT) air interface used to transmit data or signaling related to the ambient Internet of Things or the shared resource on the wireless cellular network air interface used to carry ambient Internet of Things (AIoT) small data transmission, the first device 110 receives the grouping rule information and selects to use at least one resource based on the grouping rule information, which can reduce resource usage conflicts, and thus the reliability of the first device 110 when transmitting data or signaling related to the ambient Internet of Things on the selected at least one resource is higher.In addition, for the system, the third device 130 allocates shared resources on the environmental Internet of Things air interface for the first device 110 to transmit environmental Internet of Things related data or signaling, or shared resources on the wireless cellular network air interface for the first device 110 to carry environmental Internet of Things small data transmission. Since the shared resources can be allocated to multiple first devices 110, the resource utilization of the entire system can be improved.

[0048] Optionally, in some embodiments, the resource is a shared resource on the environment Internet of Things air interface for transmitting environment Internet of Things related data or signaling, and the shared resource information further includes at least one of: environment Internet of Things subchannel size, number of environment Internet of Things subchannels, starting resource block position of the environment Internet of Things subchannel, number of resource blocks of the environment Internet of Things resource pool, time domain information of the environment Internet of Things resource pool, environment Internet of Things related channel configuration (i.e., R2D channel configuration of the environment Internet of Things and D2R channel configuration of the environment Internet of Things), and priority indication information of the environment Internet of Things. Specifically, the shared resource information is time-frequency resource information of the AIoT Uu shared resource, subchannel channel, etc., so that the first device 110 can determine the time-frequency resource of the data or signaling transmission according to the shared resource information, and the shared resource information is sent to the first device 110 in the system message, or the multicast message, or the RRC message. It is worth noting that the shared resource information can also be based on predefinition. Among them, the environment Internet of Things subchannel size (AIoT subchannel size): this IE is used to represent the AIoT subchannel size in the unit of resource blocks (PRB), which is the minimum granularity of frequency domain selected by the environment Internet of Things physical channel configuration resource, and the value of the PRB is an integer, such as 10 PRBs, 15 PRBs, 20 PRBs, etc. In particular, for the uplink environment Internet of Things physical channel, the value of the environment Internet of Things subchannel size can be one or two; and for the downlink environment Internet of Things physical channel, the value of the environment Internet of Things subchannel size is one; optionally, the environment Internet of Things subchannel size of the uplink environment Internet of Things physical channel and the environment Internet of Things subchannel size of the downlink environment Internet of Things physical channel can be the same or different.

In particular, it can be composed of consecutive PRBs or non-consecutive PRBs. Time domain information of the environment Internet of Things resource pool: this IE is used to represent the time domain information configured in the environment Internet of Things resource pool, such as the time domain length of the environment Internet of Things resource pool which can be up to 160ms; environment Internet of Things D2R channel configuration: this IE is used to represent the resource pool configuration of the D2R channel (PRDCH, the direction is from the first device 110 to the second device 120), and the first device 110 obtains the environment Internet of Things resource pool for D2R data / signaling transmission on the D2R channel after receiving / acquiring the IE.In particular, the configuration can further include any one or a combination of the following elements: 1) time domain information of the environment IoT: the time domain information indicates the corresponding time domain information of the D2R channel in a resource pool, and specifically, the time domain information can include at least one of the following: 1. start time: the time when the time domain information starts; 2. end time: the time when the time domain information ends; 3. duration: the duration of the time domain information, and the time unit of the time domain information can be chip, symbol, slot, ms, s, min, hour, etc. 2) frequency domain information of the environment IoT: the frequency domain information indicates the corresponding frequency domain information of the D2R channel in an environment IoT resource pool, and specifically, the frequency domain information can be the number of PRBs corresponding to the D2R channel in a resource pool. In particular, the frequency domain information can be continuous or discontinuous; the carrier of the frequency domain information can be 15 kHz, 180 KHZ, 360 KHZ, etc. R2D channel configuration of the environment IoT: the IE is used to indicate the resource pool configuration of the R2D channel (PDRCH, the direction is from the second device 120 to the first device 110), and after the first device 110 receives / acquires the IE, the environment IoT resource pool for R2D data / signaling transmission on the R2D channel is obtained. In particular, the configuration can further include any one or a combination of the following elements: 1) time domain information of the environment IoT: the time domain information indicates the corresponding time domain information of the D2R channel in a resource pool, and specifically, the time domain information can include at least one of the following: 1. start time: the time when the time domain information starts; 2. end time: the time when the time domain information ends; 3. duration: the duration of the time domain information; the time unit of the time domain information can be chip, symbol, slot, ms, s, min, hour, etc. 2) frequency domain information of the environment IoT: the time domain information indicates the corresponding frequency domain information of the R2D channel in an environment IoT resource pool, and specifically, the frequency domain information can be the number of PRBs corresponding to the R2D channel in a resource pool. In particular, the frequency domain information can be continuous or discontinuous. The carrier of the time domain information can be 15 kHz, 180 KHZ, 360 KHZ, etc. Priority indication information of the environment IoT: the indication information indicates the transmission priority of the environment IoT, and if the indication information exists, it means that the transmission priority of the environment IoT is the lowest.

[0049] Optionally, in some embodiments, the resource is a shared resource on the environment IoT air interface for carrying small data transmission of the environment IoT on the wireless cellular network air interface, and the shared resource information further includes at least one of the following: a data volume threshold of the small data transmission of the environment IoT, a bearer, an AIoT dedicated logical channel, time domain information of the small data transmission of the environment IoT, or frequency domain information of the small data transmission of the environment IoT.

[0050] Specifically, the shared resource information is related to AIoT specific small data transmission, so that the first device 110 performs AIoT specific small data transmission according to the AIoT specific small data transmission configuration. For example, assuming that an AIoT specific logical channel LCH_AIoT is configured with AIoT specific small data transmission, when the data carried by the LCH_aiot is less than or equal to the data volume threshold defined by the AIoT specific small data transmission, and there is AIoT specific small data transmission resource available, the first device 110 in the RRC inactive or RRC idle state can directly transmit AIoT data or signaling. The AIoT specific small data transmission configuration or system message, or multicast message, or RRC message is sent to the first device 110. In particular, the AIoT specific small data transmission configuration can also be based on a predefined. Among them, the data volume threshold of the AIoT specific small data transmission: this threshold is used to represent the data volume threshold of the first device 110 transmitting the data or signaling of the second device 120, only when the data volume of the data or signaling of the second device 120 is less than the threshold, the first device 110 can send or forward the data or signaling of the second device 120 in the inactive state. An example: AIoI-sdt-DataVolumeThreshold-R19 ENUMERATED{b98,b256,b800,b1000,space,spacesapce,space,space}, wherein Value b98 corresponds to 98 bits value byte256 corresponds to 256 bits, etc.; in some examples, if the conventional data volume threshold is multiplexed, an indication information associated with the data volume threshold is needed, which is used to indicate that the data volume threshold is now mainly used to evaluate whether the data volume of the data or signaling of the second device 120 of the first device 110 can be transmitted by small data (that is, the first device 110 in the RRC inactive state can transmit the service packet of the second device 120). In some examples, only the RA-based SDT configures the data volume threshold of the AIoT specific small data transmission; in some examples, both the RA-based SDT and the CG-SDT configure the data volume threshold of the AIoT specific small data transmission, wherein the data volume threshold of the AIoT specific small data transmission is the same; optionally, the RA-based SDT and the CG-SDT respectively configure their corresponding data volume thresholds of the AIoT specific small data transmission, such as threshold 1 and threshold 2, wherein the threshold 1 and the threshold 2 can be the same or different.Bearing: including (SRB, DRB) SRB4 ID, or other SRBx ID, or AIoT specific SRBy: if SIB4 or other SRBx is introduced, it means that SIB4 or other SRBx is configured with SDT, or it can be said that if the data or signaling of the second device 120 can be transmitted on SRB4 or other SRBx, the SRB4 or other SRBx is configured with AIoT-SDT; if AIoT specific SRBy is introduced, the SRBy only carries the data or signaling of the second device 120, and the SRBy is configured with AIoT-SDT. One example: sdt-SRB4-Indication-r17 ENUMERATED{allowed}, which means that SDT is configured for SRB4; AIoT specific logical channel, or channel between the second device 120 and the first device 110: the channel between the second device 120 and the first device 110 can be the channel between the upper layer (NAS, AIoT NAS) and AIoT-MAC. The AIoT specific logical channel, or the channel between the second device 120 and the first device 110 is used to indicate that the AIoT specific logical channel, or the channel between the second device 120 and the first device 110 is configured with AIoT-SDT. Environment Internet of Things small data transmission time domain information: this IE is used to indicate the time domain information configured in the environment Internet of Things small data transmission, specifically, it can include at least one of the following: 1. start time: the time when the time domain information starts; 2. end time: the time when the time domain information ends; 3. duration: the duration of the time domain information. Environment Internet of Things small data transmission frequency domain information: used to indicate the corresponding frequency domain information of the environment Internet of Things small data transmission, specifically, it can be the number of PRBs corresponding to one channel. In particular, the frequency domain information can be continuous or discontinuous. The carrier of the frequency domain information can be 15kHz, 180KHZ, 360KHZ, etc.

[0051] Optionally, the first information is grouping rule information, wherein the grouping rule information is used to identify different resource configurations.

[0052] In one implementation, the grouping rule information of the resources is acquired or received at the network side and the first device 110 side respectively. In another implementation, the grouping rule information of the resources is configured based on the network side, and the grouping rule information of the resources can be carried by a broadcast message, or a multicast message, or an RRC unicast message. It should be noted that the grouping rule information of the resources (which can be shared resources or resources dedicated to the first device 110) is used for grouping shared resources for transmitting environment Internet of Things related data or signaling over the environment Internet of Things air interface, and / or for grouping shared resources for carrying environment Internet of Things small data transmission over the wireless cellular network air interface.

[0053] The grouping rule information is used to identify different resource configurations. The grouping rule information is represented by at least one of the following: environment Internet of Things device type information identification, second device power storage capability identification, environment Internet of Things service type identification, area information identification, or a predefined formula.

[0054] Specifically, the grouping rule information can be represented by at least one of the following:

[0055] Method 1: The grouping rule information can be directly or indirectly represented by the following identification or index:

[0056] The mode 1 is further divided into four cases. For case 1, if the third device 130 groups the resources according to the second device type, the second device type information identifier can be used to represent the grouping rule information; the identifier is used to represent the type of the second device 120, and different identifiers can represent different types of the second device 120. Optionally, the device type information identifier can have two optional representation modes, namely implicit and explicit: for the implicit mode, an index is introduced to represent the second device type, which is agreed between the network side and the first device 110, and both ends determine the device type represented by the index, and the third device 130 indicates the second device type through the index. If this method is used, the second device type is transparent to the base station. For the explicit mode, the second device type is directly defined to represent, such as device (device) 1, device (device) 2a, and device (device) 2b. If this method is used, the second device type is not transparent to the base station. For case 2, if the third device 130 groups the resources according to the power storage capacity of the second device 120, the power storage capacity identifier of the second device 120 can be used to represent the grouping rule: the identifier information is used to represent the power storage capacity of the second device 120, and the optional mode has two kinds: one possible implementation is to directly display the power storage capacity level of the second device 120 by defining high, medium, and low. For example, if the second device 120 is a charging device, the level is high. Optionally, the power storage capacity level corresponds to different communication times of the second device 120; another possible implementation is to implicitly indicate the power storage capacity level of the second device 120 by the communication time that can be maintained after the second device 120 is charged. For case 3, if the third device 130 groups the resources according to the service type of the environmental Internet of Things, the service type identifier of the environmental Internet of Things can be used to represent the grouping rule: the identifier information is used to represent the type of the environmental Internet of Things service, and different identifiers represent different service types. The environmental Internet of Things service type at least includes one of the following: inventory service, control service (such as read command, write command, activation command, or deactivation command, etc.), sensing information sending service, etc. For case 4, if the third device 130 groups the resources according to the area information, the area information identifier can be used to represent the grouping rule, and the identifier information is used to represent the area where the first device 110 is located. The area can be the actual geographic location of the first device 110, including any one or combination of the following: longitude, latitude, or height, etc. It can also implicitly represent the geographic location of the first device 110 through the RSRP or RSRQ or SINR measured by the first device 110; optionally, the location can also be pre-divided by the network side, and when the first device 110 is deployed in an area, the area information can be used to identify the approximate location of the first device 110, and the unit can be meters.

[0057] Way 2: The grouping rule information can be expressed by the following pre-defined formula;

[0058] In some cases, the network side considers at least one information related to the second device 120 when grouping the AIoT resources, such as the second device type, the power storage capability of the second device 120, the area information, or the service type. The grouping rule information can be expressed by the following pre-defined formula:

[0059] X% second device type + Y% second device type + Z% area information + W% service type + Q% other information

[0060] Wherein, the second device type, the power storage capability of the second device 120, the area information, and the service type are explained above, the other information is a reserved information that can appear in the future, and the reserved information can define specific information related to the second device 120; X, Y, Z, W, and Q respectively represent the percentage of each information, X% + Y% + Z% + W% + Q% = 100%, and each information in the formula is optional.

[0061] For example, if the network side considers the second device type and the power storage capability of the second device 120 when grouping the AIoT resources, wherein the second device type accounts for 50%, and the power storage capability of the second device 120 accounts for 50%. The formula of the resource grouping rule information is:

[0062] 50% second device type + 50% second device type

[0063] It is worth noting that the percentage can be fixed or variable, and can be defined by the network, or pre-defined, or suggested or configured by the first device 110. The first device 110 suggestion means that the first device 110 sends the percentage information of different information to the network side through the UE assistance information. The grouping rule information can be sent to the first device 110 through system messages, multicast messages, or unicast messages. It can also be implicitly informed to the first device 110 through a pre-defined way.

[0064] In summary, the network side configures the resource grouping rule information to the first device 110, and the first device 110 evaluates or compares the rule or information with its own state information and / or the information of the second device 120 it manages, selects a suitable resource block (or multiple resource blocks), and transmits AIoT data or signaling on the selected resource block. Optionally, the grouping rule information can be pre-defined. Finally, based on the second device 120 and / or the service characteristics, the fine-grained resources (grouping rule information) are configured, so that the first device 110 selects suitable resources based on the second device 120 it manages, reduces the interference of the first device 110, and ensures the reliable transmission of environmental Internet of Things service data.

[0065] For better illustration, the first device selects a resource for transmitting the AIoT related data or signaling based on the first information (the first information can be the grouping rule information), and transmits the AIoT related data or signaling; an actual example is taken to further illustrate. It is assumed that the network side groups the resources based on the device type, and the device type is sent to the UE reader through the grouping rule information. The flowchart of the example is shown in FIG. 3, and specifically includes the following steps.

[0066] Step S301: The third device 130 sends the grouping rule information to the first device 110, and the grouping rule information carries the device type identifier. Specifically, the third device 130 configures the shared resource on the wireless cellular network air interface for carrying the AIoT small data transmission based on the second device type, and the configured shared resource and the device type identifier are implicitly associated through the RRC message, or the system message, or the multicast message.

[0067] Step S302: The first device 110 evaluates and compares the types of the second devices 120 managed / associated by itself, and selects one or more appropriate shared resource pools, for example, the first device 1101 only manages the second devices 120 of the device type device1, and therefore, when the first device 110 receives the shared resource configured based on different device types, only the shared resource configured for the device type device1 is selected.

[0068] Step S303: The first device 110 transmits the AIoT data or signaling on the selected shared resource.

[0069] It is worth noting that in some embodiments, the grouping rule information or the allocation rule configuration message can also be applicable to the configuration of dedicated resources. The dedicated resources are no longer shared resources, but first device 110 level dedicated resources, that is, the resources are not shared with other first devices 110.

[0070] In an implementation manner, the grouping rule of the resource, the shared resource grouping rule can be implemented based on the network, or can be predefined, wherein the grouping rule of the resource includes at least one of the following:

[0071] Rule 1: determining the resource corresponding to the type of the second device 120 based on the type of the second device 120;

[0072] The third device 130 can divide different resource blocks according to the second device type. For example, for device 1, the configuration of time-frequency resources is the same, such as configuring different uplink and downlink frequency domain information; for device 2b, the configuration of time-frequency resources is the same, such as configuring the same uplink and downlink frequency domain information, and the like. The first device 110 managing the same type of second device 120 uses the same resource block.

[0073] Rule 2: Determine the resource corresponding to the type of the second device 120 based on the type of the business of the environment Internet of Things;

[0074] The third device 130 can divide the resource into different resource blocks according to the type of the business of the environment Internet of Things. The environment Internet of Things has different types of businesses, such as inventory, control, or sensing information reporting, and each type of business has different transmission requirements, but is relatively fixed, so the third device 130 can divide the resource into finer resource blocks according to the different types of businesses of the AIoT. In this way, the first device 110 performing the same type of environment Internet of Things business uses the same resource block.

[0075] Rule 3: Determine the resource corresponding to the type of the second device 120 based on the power storage capacity of the second device 120;

[0076] The third device 130 can divide the resource into different resource blocks according to the different power storage capacities of the second device 120. The power storage capacities of different second devices 120 are different, and the power storage capacity of the second device 120 will affect the configuration of the environment Internet of Things resource pool, for example, two second devices 120 (second device 1201 and second device 1202) have the same distance from the first device 110, but the power storage capacity of the second device 1201 is weak, so the second device 1201 transmits the environment Internet of Things message at a slower rate, resulting in a longer transmission time. Therefore, the network side can divide the resource blocks according to the power storage capacity level of the second device 120. The first device 110 managing the power storage capacity of the second device 120 uses the same resource block.

[0077] Rule 4: Determine the resource corresponding to the type of the second device 120 based on the area information;

[0078] The third device 130 can divide the resources into different resource blocks according to the area information. In the environmental IoT, if the inventory process is performed in a factory, for example, there are different work areas in the factory, and there can be multiple first devices 110 in each work area. Assuming that the work factory is divided into three areas, area #1, area #2, and area #3, the third device 130 can configure resource blocks with finer granularity according to the work area location information, for example, resource block 1 for the work area (area) #1, resource block 2 for the work area (area) #2, and resource block 3 for the work area (area) #3. The first devices 110 in the same area use the same resource block.

[0079] It is worth noting that the third device 130 can obtain the information of the second device 120 (for example, the type of the second device, the type of the service of the environmental IoT, the power storage capacity of the second device, and the area information) through the first device 110 reporting to the network side, or through the core network notifying the third device 130.

[0080] In summary, the network side divides the resources into multiple resource blocks with finer granularity, so that the first device 110 selects one (or multiple) suitable resource from multiple sets of resource information for transmitting the data or signaling of the environmental IoT. For example, assuming that the first device 1101 and the first device 1102 receive resource configurations (time-frequency domain configurations) through broadcast messages, and the broadcast messages carry 12 sets of resource configurations. If the grouping rule is based on the area location information of the first device 110, then the first device 1101 selects to use the resource configuration 1 corresponding to its area according to its area. The first device 1102 selects to use the resource configuration 2 corresponding to its area according to its area. Through the grouping of resources, on the one hand, the resource utilization rate of the environmental IoT is improved, and on the other hand, the interference between the first devices 110 can be reduced, and to some extent, the resource conflict can be reduced.

[0081] In an implementation manner, the first information includes at least one of the following: a configuration index of the resource, the configuration index being used to identify the configuration of different resources.

[0082] In particular, the configuration index of the resource can include a configuration index of a shared resource or resource used for transmitting AIoT related data or signaling on an AIoT air interface. The configuration index of the shared resource or resource used for transmitting AIoT related data or signaling on an AIoT air interface is used to represent a configuration of a shared resource or resource used for transmitting AIoT related data or signaling on an AIoT air interface, and different configuration indexes (index values) represent different configurations of a shared resource or resource used for transmitting AIoT related data or signaling on an AIoT air interface. Considering that a first device 110 can manage different second devices 120, each second device 120 can perform different AIoT services, in addition, the grouping method of multiple resource pools is introduced above, and a first device 110 can simultaneously support multiple configurations of an AIoT air interface. Therefore, a configuration index of a shared resource or resource used for transmitting AIoT related data or signaling on an AIoT air interface can be introduced to distinguish different configurations of a shared resource or resource of an AIoT air interface. Optionally, the configuration index of the resource is associated with configured resource information, including at least one of the following: size of a subchannel, starting position of a subchannel, frequency domain information, starting position of frequency domain information, time domain information, starting time of time domain information, duration of time domain information, and periodicity information (such as periodic interval) of the resource.

[0083] In an implementation manner, the first information includes at least one of the following: a configuration (resource) index used to identify a configuration representing AIoT small data transmission: the configuration index is used to represent an AIoT small data transmission configuration, and different index values represent different AIoT small data transmission configurations. Considering that a first device 110 can manage different second devices 120, each second device 120 can perform different AIoT services, in addition, the grouping method of multiple resource pools is introduced above, and a first device 110 can simultaneously support multiple configurations of an AIoT small data transmission. Therefore, an AIoT small data transmission configuration index can be introduced to distinguish different AIoT small data transmission configurations. In particular, the index is associated with configured resource information, including at least one of the following: size of a subchannel, starting position of a subchannel, frequency domain information, starting position of frequency domain information, time domain information, starting time of time domain information, duration of time domain information, and periodicity information (such as periodic interval) of the resource.

[0084] In an implementation manner, the method further includes AIOT operation interaction between the first device 110 and the second device 120 or the group of second devices 120, which is described in the prior art and will not be repeated here.

[0085] In an implementation manner, optionally, the method further includes that the first device 110 sends the request information of the resource.

[0086] The request information includes at least one of the following: information related to the second device 120, an association ID, a configuration index of the resource, or a resource pattern, wherein the association ID is used to represent information of the second device 120 managed or associated by the first device 110 and / or a service of the second device 120, the configuration index of the resource represents different resource configurations, and the resource pattern is used to represent resource usage requirements of the air interface. Optionally, the information related to the second device 120 and / or the service type of the second device 120 includes at least one of the following: a type of the second device 120, a power storage capability of the second device 120, a service type of the second device 120, a period of an environmental IoT service, a size of the environmental IoT service, regional information, or a number of the second device 120.

[0087] Optionally, the information related to the second device 120 (the information related to the second device 120 and / or the service type information of the second device 120) sent by the first device 110 to the network side is a kind of display representation of request information, so that the third device 130 configures resources according to the request information. The request information includes at least one of the following:

[0088] 1. The type of the second device 120; used to represent the type of the second device 120, and the third device 130 can divide different resources according to the type of the second device. For example: for device1, the configuration of time-frequency resources is the same, such as configuring different uplink and downlink frequency domain information; for device2b, the configuration of time-frequency resources is the same, such as configuring the same uplink and downlink frequency domain information. The first device 110 managing the same type of second device 120 uses the same resource;

[0089] 2. The power storage capability of the second device 120: the third device 130 can divide different resources according to the service type of the environmental IoT. AIoT has different service types, such as inventory, control, or sensing information reporting, and each service type has different but relatively fixed transmission requirements, so the third device 130 can divide finer resources according to different service types of AIoT. The first device 110 performing the same type of environmental IoT service uses the same resource;

[0090] 3. AIoT service type: used to represent the type of AIoT service, the third device 130 can divide different resources according to the type of AIoT service. AIoT has different service types, such as inventory, control, or perception information reporting, each type of transmission requirement is different but relatively fixed, so the third device 130 can divide finer resources according to the different service types of AIoT. The first device 110 performing the same type of AIoT service uses the same resource.

[0091] 4. AIoT service period: used to represent the period of AIoT service execution, here the interval time between periods needs to be introduced, for example, performing inventory service, the interval time is 20 minutes, indicating that the inventory service is executed once every 20 minutes. The time unit of the interval time can be millisecond, second, minute, hour, day, or week, etc. The AIoT service period includes:

[0092] 1) AIoT service start time: used to represent the start time of AIoT service execution;

[0093] 2) AIoT service execution time: used to represent the duration of AIoT service execution, the time unit can be millisecond, second, minute, hour, day, or week, etc.

[0094] 5. AIoT service size: used to represent the message size of AIoT service, such as inventory message is 98 bits, 128 bits, etc. The unit can be bit or byte.

[0095] 6. Area information: the third device 130 can divide different resources according to the type of AIoT service. AIoT has different service types, such as inventory, control, or perception information reporting, each type of transmission requirement is different but relatively fixed, so the third device 130 can divide finer resources according to the different service types of AIoT. The first device 110 performing the same type of AIoT service uses the same resource.

[0096] 7. The number of second devices 120: used to indicate the number of AIoT managed by the first device 110, the number of AIoT has three representations: one possible implementation is to directly display the identity of the actual number of second devices 120, that is, how many second devices 120 the first device 110 manages, for example, the number of second devices 120 is 10, which means that the number of AIoT currently managed by the first device 110 is 10; another possible implementation is to roughly indicate the number of second devices 120, if it is high, medium, or low classification, or index implicitly indicates the number of second devices 120. An exemplary table is shown in Table 1 below, through which the third device 130 can know how many second devices 120 the first device 110 manages.

[0097] Table 1: correspondence between index and number range of second devices 120

[0098] 3) Method 3: implicitly indicate the number of second devices 120 by area.

[0099] In some examples, the number of second devices 120 can be represented according to the area information, for example, area 1 can represent 18 second devices, and area 2 can represent 18 second devices; wherein the association between the area information and the device can be configured by the network side (gNB or CN network element).

[0100] Optionally, the association ID sent by the first device 110 to the network side is a kind of implicit representation of the request information.

[0101] Specifically, the first device 110 sends the association ID to the third device 130, and the third device 130 can configure appropriate resource information for the first device 110 to transmit environmental Internet of Things related data or signaling on the environmental Internet of Things air interface according to the received association ID. The association ID can be associated with at least one of the following information: the device type of the AIoT managed by the first device 110, the service type, the device power storage capacity, the service period, the service execution time, the service start time, or the service size, etc. For the association ID, there can be at least one possible way:

[0102] Manner 1: The association ID is uniquely defined by the network, which can be uniquely defined by a Public Land Mobile Network (PLMN), uniquely defined by an AIoT CN network element (AIoT function, AMF, AF), or uniquely defined by a base station. It can be achieved by defining a table, where index is the association indication information ID, which can be associated with at least one of the following: AIoT device type, service type, device power storage capacity, service period, service execution time, service start time, or service size, etc. Several examples are shown in Table 2-3 as follows:

[0103] Table 2: Correspondence between association ID and device information

[0104] Table 3: Correspondence between association ID and device information

[0105] Manner 2: The association ID is configured by the network, and the association ID and the service information of the second device 120 and / or the service information of the second device 120 can be hierarchically mapped, and the service information of the second device 120 and / or the service information of the second device 120 can be any one or more of the following: AIoT device type, service type, device power storage capacity, service period, service execution time, service start time, or service size.

[0106] Table 4: Correspondence between association ID and device information

[0107] Manner 3: The association ID is a combination of network configuration and predefinition, which is associated with the service information of the second device 120 and / or the service information of the second device 120. Specifically, the service information of the second device 120 and / or the service information of the second device 120 can be a network predefinition (index), and the network can configure a temporary index for the service information of the second device 120 and / or the service information of the second device 120 to the UE, i.e., the association ID. In other words, manner 3 can be understood as a combination of manner 2 and manner 1, and an example is shown in Table 5 as follows:

[0108] Table 5:

[0109] Optionally, the configuration index of the resource sent by the first device 110 to the network side is a kind of implicit representation of the request information.

[0110] In particular, the first device 110 directly sends a configuration index of the resource, such as an Ambient Internet of Things Small Data Transmission Configuration Index, which is used to represent different Ambient Internet of Things Small Data Transmission Configurations, including time-frequency domain information of resources used for transmitting Ambient Internet of Things related data or signaling on the Ambient Internet of Things air interface, etc. This is because different service types and different device types correspond to different Ambient Internet of Things Small Data Transmission Configurations, and when requesting configuration release or reconfiguration, it is necessary to indicate which set of Ambient Internet of Things Small Data Transmission Configurations. In other words, the configuration index can be the index configured when the first device 110 and the third device 130 first connect, and when the first device 110 sends a request for resource configuration again, the index information of the previous configuration can be sent to the third device 130 through the resource configuration request message, and the third device 130 can reconfigure the resource after receiving the configuration index information. In particular, it can also be the configuration index of the resource used for transmitting Ambient Internet of Things related data or signaling on the Ambient Internet of Things air interface.

[0111] Optionally, the resource pattern sent by the first device 110 to the network side is a kind of implicit representation of the request information.

[0112] In particular, the resource pattern at least includes at least one of the following:

[0113] 1. The number of preferred occupied RBs: The information is used to represent the number of PRBs that the first device 110 / AIoT reader prefers to occupy, which can be composed of consecutive physical resource blocks (PRBs) or non-consecutive PRBs;

[0114] 2. The starting position of the number of preferred occupied RBs: The information is used to represent the starting RB position of the number of PRBs that the first device 110 / AIoT reader prefers to occupy;

[0115] 3. The length of time preferred to be occupied: The information is used to represent the duration of time that the first device 110 / AIoT reader prefers to use PRB resources, and the time unit can be chip, millisecond (ms), second (s), minute (min), hour (hour), day (day), week (week);

[0116] 4. Preferred occupation period: the information is used to indicate the period information that the first device 110 / AIoT reader prefers to use the resource, which contains a period interval, such as the interval is 20 min, i.e. the first device 110 / AIoT reader prefers to use the resource information every 20 min, and the length of the time used is the length of the preferred occupation time.

[0117] 5. Preferred occupation time start time: the information is used to indicate the start time that the first device 110 / AIoT reader prefers to use the resource.

[0118] In an application scenario, as shown in FIG. 4, the resource is a shared resource on a wireless cellular network air interface for carrying environmental IoT small data transmission, and the first device 110 sends the request information of the resource, specifically, the first device 110 sends the second device 120 or service information managed or associated by the first device 110 to the third device 130, and the request information is used to assist the third device 130 to more reasonably configure the shared resource on the wireless cellular network air interface for carrying environmental IoT small data transmission required by the first device 110. The information can be carried in the first device 110 capability reporting message, the UAI (UE Assistance Information, UAI) message, or the dedicated resource configuration request message. The flowchart of the example includes the following steps:

[0119] Step S401: The first device 110 sends the second device 120 or service information managed or associated by the first device 110 to the third device 130, and the information is used to assist the third device 130 to more reasonably configure the shared resource on the wireless cellular network air interface for carrying environmental IoT small data transmission required by the first device 110. The information can be carried in the first device 110 capability reporting message, the UAI message, or the dedicated shared resource configuration request message.

[0120] Step S402: The third device 130 groups the shared resource on the wireless cellular network air interface for carrying environmental IoT small data transmission into multiple shared resource blocks on the wireless cellular network air interface for carrying environmental IoT small data transmission with finer granularity, and the grouping rule can be based on a pre-defined rule (at this time, the third device 130 and the first device 110 both set the same rule) or based on the implementation of the network side.

[0121] Step S403: The first device 110 receives the shared resource grouping rule information for carrying the environmental IoT small data transmission over the wireless cellular network air interface sent by the third device 130. The grouping rule information can be sent to the first device 110 through a broadcast message, or a groupcast message, or an RRC unicast message. In particular, it can also be based on a predefinition.

[0122] Step S404: The first device 110 selects the shared resource for carrying the environmental IoT small data transmission over the wireless cellular network air interface. The first device 110 selects the shared resource suitable for itself from multiple sets of shared resources for AIoT data transmission or signaling by evaluating or comparing the shared resource grouping rule information for carrying the environmental IoT small data transmission over the wireless cellular network air interface in step 3 and the information or state owned by itself. Here, the way to solve the resource usage conflict, the implementation scheme of the conflict resolution, can be based on network configuration.

[0123] Step S405: The first device 110 evaluates the AIoT SDT condition, i.e., if the data or signaling of the second device 120 to be sent at the first device 110 meets the AIoT SDT condition, the first device 110 does not need to switch to the radio resource control (RRC) connected state, and directly transmits the data or signaling of the second device 120 to the network side in the RRC inactive state or the RRC idle state.

[0124] Step S406: When the first device 110 starts the AIoT SDT, the first device 110 transmits the AIoT data or signaling to the third device 130 over the shared resource selected by the first device 110 for carrying the environmental IoT small data transmission over the wireless cellular network air interface.

[0125] It is worth noting that step S404 and step S405 can be combined into one step.

[0126] The flowchart for the example of the request information is shown in FIG. 5, which specifically includes the following steps:

[0127] Step S501: The first device 110 sends the second device 120 or service information to the third device 130. In particular, the AIoT SDT configuration request message is a first device 110 capability information message, a UAI message, or other newly introduced RRC message. The AIoT SDT configuration request message can include at least one of the following: an AIoT SDT configuration index, a type of the second device 120, an environmental Internet of Things service type, a power storage capability of the second device 120, regional information, a number of the second device 120, an environmental Internet of Things service period, an environmental Internet of Things service size, an environmental Internet of Things service start time, and an environmental Internet of Things service execution time.

[0128] Step S502: The third device 130 receives the AIoT SDT configuration request message sent by the first device 110, and can group shared resources on a wireless cellular network air interface for carrying environmental Internet of Things small data transmission into multiple shared resource blocks on a wireless cellular network air interface for carrying environmental Internet of Things small data transmission with finer granularity according to the content of the AIoT SDT configuration request message.

[0129] Step S503: The first device 110 is configured with appropriate shared resources on a wireless cellular network air interface for carrying environmental Internet of Things small data transmission. In particular, multiple first devices 110 can send the AIoT SDT configuration request message at the same time or at different times, and the third device 130 can configure the shared resources based on the implementation.

[0130] In another application scenario, as shown in FIG. 6, the shared resources are environmental Internet of Things air interface AIoT Uu shared resources, and the first device 110 sends the request information of the shared resources, specifically, the first device 110 actively sends an AIoT Uu configuration request message to the third device 130 to assist the third device 130 in better configuring Uu shared resources. The information can be carried in a first device 110 capability reporting message, a UAI message, or a dedicated shared resource configuration request message. The flowchart of the example includes the following steps:

[0131] Step S601: The first device 110 actively sends an AIoT Uu configuration request message to the third device 130 to assist the third device 130 in better configuring Uu shared resources. The AIoT Uu configuration request content is the same as the AIoT SDT configuration request content in scenario 1 and / or the same way; to achieve the above function, the specific implementation includes at least one or more of the following implementation schemes.

[0132] Step S602: The third device 130 groups the AIoT Uu shared resources into a plurality of AIoT Uu shared resource blocks with finer granularity, and the grouping rule can be predefined or implemented by the network side.

[0133] Step S603: The first device 110 receives the AIoT Uu shared resource grouping rule information sent by the third device 130, and the grouping rule information can be sent to the first device 110 through a broadcast message, a multicast message, or an RRC unicast message. In particular, it can also be predefined.

[0134] Step S604: The first device 110 selects shared resources on the environmental IoT air interface for transmitting environmental IoT related data or signaling. The first device 110 selects suitable shared resources for AIoT data or signaling transmission from multiple sets of shared resources by evaluating or comparing the grouping rule information in step 3 and its own information. In particular, the way to solve the resource usage conflict needs to be solved here, and the conflict resolution implementation scheme can be based on the signal side.

[0135] Step S605: The first device 110 transmits AIoT data or signaling on the selected AIoT Uu shared resource.

[0136] For the AIoT Uu shared resource scenario, the request information includes at least one of the following: information related to the second device 120, and / or service type information, association ID of the second device 120, or configuration index of the resource, wherein the association ID is used to represent the information of the second device 120 and / or the service of the second device 120 managed or associated by the first device 110, the configuration index of the resource represents different resource configurations, and the resource pattern is used to represent the resource usage demand of the air interface. Optionally, the information related to the second device 120 and / or the service type of the second device 120 includes at least one of the following: the type of the second device 120, the power storage capacity of the second device 120, the service type of the second device 120, the period of the environmental IoT service, the size of the environmental IoT service, the area information, and the number of the second device 120. The request message can be an RRC message, a UAI message, or other newly introduced messages. Since the above content has been described in the foregoing, it will not be described here.

[0137] In summary, when the third device 130 configures resources for the first device 110, it needs to know some information of the second device 120 managed by the first device 110, so as to determine whether the related service of AIoT is suitable for using the pre-configured uplink dedicated resource for transmission. In topology 2, in some cases, the information related to the environmental Internet of Things is transparent to the base station, but is partially visible to the first device 110. Therefore, it can be considered that the first device 110 sends a request message of AIoT resource configuration to the third device 130, to assist the third device 130 to better perform AIoT resource configuration. The request message of the second device 120 or service information is the first device 110 capability information, UAI message, or other newly introduced RRC message. Alternatively, the configuration request information can be periodically sent, or not periodically sent. In particular, the first device 110 sends the information to assist the network to configure resources (resources on the environmental Internet of Things air interface for transmitting data or signaling related to the environmental Internet of Things, and / or resources on the environmental Internet of Things air interface for transmitting data or signaling related to the environmental Internet of Things).

[0138] In an implementation manner, optionally, the method further comprises sharing resource or resource collision avoidance. In addition, considering that if multiple first devices 110 use the same resource, collision is inevitable when selecting the sharing resource or resource, and once collision occurs, the efficiency of data transmission will be reduced. Therefore, it should be necessary to solve the sharing resource or resource collision of AIoT.

[0139] Specifically, the sharing resource collision avoidance is determined based on at least one of the following manners:

[0140] Method 1: By configuring different time information, the time that different first devices 110 use the shared resource is limited, so that the conflict due to selecting the same time on the same time slot can be reduced. The possible method can be at least one of the following: Method 1: Directly configure the time information of using the shared resource. When the third device 130 configures the shared resource, it also needs to configure different time of using the shared resource for different first devices 110, and the first device 110 starts to use the resource according to the configured time of using the shared resource. For example, there are three first devices 110 using the same shared resource, and the third device 130 configures different time of using the shared resource for the three first devices 110, which are T1, T2, and T3. If the first device 110 has data or signaling to be transmitted, it starts to transmit the AIoT data or signaling using the shared resource at the configured time. If the first device 110 has no data or signaling to be transmitted, it can skip and not use the shared resource at the configured time. The time information of using the shared resource (one or a group of time information of using the shared resource) is configured as follows: it can be sent to the first device 110 through a broadcast message, such as [T1, T2, T3, T4], the first device 110 randomly selects a time information of using the shared resource, and the first device 110 sends the AIoT data or information according to the selected time information. It can also be sent to the first device 110 through a dedicated information (RRC message), and here each first device 110 only needs to send one time information, such as T1, the first device 110 randomly selects a time information of using the shared resource. The first device 110 sends the AIoT data or information according to the received time information. Method 2: Use the shared resource based on random number [similar to time slot aloha]. That is, the network side can randomly allocate a Q, the first device 110 generates a random number based on the Q value, and uses the shared resource based on the order of the random number.

[0141] Manner 2: By configuring different frequency point information, the frequency domain of the shared resource used by different first devices 110 is limited, so as to reduce the conflict in the same time slot due to the selection of the same frequency. For example, the third device 130 divides the configured frequency domain resource into different frequency points, such as F1, F2, and F3. By configuring different frequency point information, the frequency domain of the shared resource used by different first devices 110 is limited, including the following two methods: Method 1: The frequency point information and the shared resource information are sent to the first device 110 through a broadcast message, and the first device 110 randomly selects a frequency point to send AIoT data or information, which can reduce the problem of being unable to receive due to the conflict in the same time slot; Method 2: Different frequency point information is sent to the first device 110 through dedicated information (RRC message), and the first device 110 sends AIoT data or information according to the received frequency point information.

[0142] Manner 3: By limiting the number of first devices 110, the probability of resource conflict is reduced. Here, a threshold value of the number of first devices 110 is introduced, and the value of the number threshold is an integer. In addition, the number threshold can be fixed, such as a protocol stipulating that AIoT shared resources can be shared to at most 2 first devices 110; or it can be variable, such as based on the size of the shared resource being large, AIoT shared resources can be shared to 4 first devices 110, or the duration of the AIoT service being long, AIoT shared resources can be shared to at most 2 first devices 110.

[0143] Manner 4: In combination with Manner 1 and Manner 2, a dedicated time-frequency resource is allocated to each first device 110, that is, a plurality of separate time-frequency resource blocks are divided in the shared resource, and each time-frequency resource block is allocated to a first device 110 to reduce resource conflict.

[0144] In summary, based on the above-mentioned shared resource conflict avoidance method, the probability of shared resource conflict can be reduced as much as possible, so as to improve the efficiency of data transmission.

[0145] In an implementation manner, optionally, the method further includes AIoT UU conflict avoidance.

[0146] When the shared resource is an AIoT Uu shared resource, the AIoT Uu shared resource collision avoidance is determined based on at least one of the following manners: a signal transmitted between the detected third device 130 and the second device 120 is determined to determine resource usage, wherein the signal includes a preamble signal, a midamble signal, a postamble signal, a control signal, the preamble signal includes a signal indicating a start and / or a synchronization signal; a collision avoidance signal transmitted between other second devices 120 and third devices 130 is detected, wherein the collision avoidance signal carries at least time information; a carrier wave (CW) signal transmitted between other second devices 120 and third devices 130 is detected.

[0147] Specifically, the AIoT Uu shared resource collision avoidance is determined based on at least one of the following manners:

[0148] Manner 1: The first device 110 detects the signal sent between other first device 110 and second device 120, which can be a preamble signal, midamble signal, postamble signal, control signal, the preamble signal can include a start of indicator signal, and / or a synch signal. For example, the first device 1101 detects the signal sent between other first device 1102 and second device 120, there are four cases: case 1: if the detected signal is a preamble signal, it means that the related resource of the preamble signal has been used; case 2: if the detected signal is a midamble signal, it means that the related resource of the preamble signal has been used; case 3: if the detected signal is a postamble signal, it means that the related resource of the preamble signal has been used; case 4: if the detected signal is a control signal, it means that the related resource of the control signal has been used. For case 1, case 2, case 3, the first device 110 detects the signal, knows that the resource is used, and can avoid conflict by at least one of the following methods: method 1: introduce a detection duration, if the first device 110 receives and detects the signal as a preamble signal, or a midamble signal, or a control signal within the duration, the first device 110 knows that the time-frequency resource is occupied, and then does not select the time-frequency resource. Method 2: introduce a time offset, if the first device 110 receives and detects the signal as a preamble signal, or a midamble signal, or a control signal at a certain time, the first device 110 does not detect the signal any more, and can select the resource directly after the defined time offset. Or, after the defined time offset, the first device 110 receives and detects the signal again, if the signal is not received or detected, the first device 110 can select the resource. For case 4, the first device 110 detects the signal, knows that the resource has been used, and to prevent ping-pong, continues to detect for a period of time Tz, if the signal is not received or detected within the period of time Tz, the first device 110 can select the resource. The duration, time offset, and time Tz can be configured by the network or predefined.

[0149] Manner 2: The first device 110 detects the conflict avoidance signal sent between other first device 110 and AIoT, which is used to avoid multiple first devices 110 using the same resource information. The conflict avoidance control signal can carry information to indicate the first device 110 to avoid selecting the same resource information, and the information at least includes time information TS to indicate that the resource will be continuously used for Ts time, and the first device 110 can use the resource after Ts time after receiving and detecting the signal. The time T information TS can be configured by the network or predefined.

[0150] Manner 3: The first device 110 detects the CW signal sent by other first devices 110 or the first device 110 and the AIoT; the CW node can be the first device 110 or an independent node. If the CW is an independent node, the node can also send uplink / downlink resources to the second device 120 using the configured resource pool. Manner 3 is divided into two cases: case 1: the CW signal is a downlink signal without frequency offset; case 2: the CW signal is an uplink signal with frequency offset. It is worth noting that the signal detected by the first device 1101 is the CW downlink signal, and the conflict avoidance method is the same as manner 1, which will not be repeated here; when the signal detected by the first device 1101 is the CW uplink signal, it is also necessary to detect the frequency offset information in the other control signal. If both signals are received and detected, the first device 110 will no longer detect the signal, and a time offset can be defined. After the time offset information, the resource is directly selected. The specific method is the same as method 2 in manner 1, which will not be repeated here.

[0151] In addition, in some embodiments, in order to save energy, the network side defines the period of time for the first device 110 to receive or detect the signal.

[0152] In summary, through the above method, the conflict between different first devices 110 due to the selection of the same time-frequency resource can be avoided, the successful transmission of data is ensured, and the data transmission efficiency is improved.

[0153] In an existing technology, if the configured resources are not used for a long time, it will cause waste of resources, so it can be released. The so-called release can be understood as the configured resources for transmitting small data are not used for transmitting small data packets, and the traditional time-frequency resources are given, so as to alleviate the problem of tight time-frequency resources. In new radio small data transmission, since in new radio (NR), the types of small data packet services covered are more diverse, such as bursty small data packets, there is no clear configuration of resources that need to be released under what circumstances. Only reconfiguration is needed. However, for environmental Internet of Things, the environmental Internet of Things small data transmission (AIoT SDT) mechanism is more similar to the long-term evolution small data transmission (LTE SDT) mechanism. This is because environmental Internet of Things data usually has small traffic, no latency requirement, and predictable transmission, which is not a bursty service. From the perspective of resource saving, the release rule of pre-configured shared resources needs to be considered.

[0154] Therefore, the present disclosure proposes a method of wireless communication to solve the above problems.

[0155] Figure 7 illustrates one of the flow charts of the method of wireless communication provided by the present disclosure, as shown in Figure 7, the method can be applied to the first device 110 (the first device 110 can be a UE reader or a UE, as shown in Figure 1). The method comprises:

[0156] Step H10: The first device 110 acquires or receives the second information of the third device 130, wherein the second information is an indication information or a release condition of releasing or reconfiguring the resources of the transmission environment Internet of Things related data or signaling;

[0157] Step H20: The first device 110 releases the selected resources of the transmission environment Internet of Things related data or signaling based on the second information; optionally, the third device 130 can reconfigure the resources of the transmission environment Internet of Things related data or signaling based on the second information.

[0158] Specifically, the release means that the configured resources are not available, and specifically, the resources can be shared resources, etc. The information has been stated throughout the text and will not be repeated here. Optionally, the second information can also be predefined, and the second information is configured by the third device 130, which can be directly in the broadcast, or multicast, or unicast message. The above-mentioned rules and methods of resource release based on the deployment scenario and characteristics of the environment Internet of Things can further ensure the utilization rate of the environment Internet of Things resources.

[0159] In some embodiments, in step H10, the release condition is time information threshold, time offset, and / or can also be number information threshold.

[0160] Specifically, the release condition of the resources can contain any at least one of the following:

[0161] 1. Release condition 1: introduce a time information Ta threshold. Specifically, a time information Ta threshold can be introduced, which can be associated with the resource configuration information. The time information Ta can be used to indicate that if no data or signaling of the ambient IoT service is received on the configured resource within the time range defined by the time information Ta threshold, the associated resource will be released to the NR resource, i.e. no longer as a resource, which can be used to carry the transmission of legacy NR data or signaling, or the transmission of vehicle-to-everything signaling, etc. The value of the time information Ta threshold is an integer or a set of integers, for example, this information occupies three bits, and the values are 1, 2, 3, 4, 5, 6; the time unit of the time information Ta threshold can be one of the following: chip, AIoT-slot, symbol, NR slot, sub-frame, frame, ms, s, min, hour, day, week. In addition, in order to avoid the difference between the time threshold information calculated by the network side and the first device 110 side, a time offset can also be introduced, which is used to align the time of resource use calculated by the network side and the first device 110 side, or the time of resource start use, or the time of resource end use. Optionally, the time offset can be used at the network.

[0162] 2. Release condition 2: introduce a number information Num threshold. Specifically, a number information Num threshold can be introduced, which can be associated with the AIoT resource configuration information. The number information Num can be used to indicate that if the configured resource is not used for a plurality of times, the plurality of times refers to the number of times being greater than or equal to the configured number information Num threshold, then the associated resource will be released to the NR resource, i.e. no longer as a resource pool, which can be used to carry the transmission of legacy new radio (legacy NR) data or signaling, or the transmission of vehicle-to-everything signaling, etc.

[0163] 3. The time information Ta threshold, and / or the number information Num threshold is configured by the third device 130 to the first device 110. For example, if the time information Ta threshold is 1 hour, the network side calculates that after reaching one hour, the configured resource is not used, the time information Ta threshold. In addition, the first device 110 receives this information, and can also know that the resource has been released.

[0164] In some examples, the indication information of the AIoT shared resource release can be directly introduced in the broadcast or the multicast. One possible representation of the indication information of the AIoT shared resource release is: if the indication information is disable, it means that the shared resource related to the indication information can continue to be used; if the indication information is enable, it means that the shared resource related to the indication information can continue to be used. The UE reader releases the resource according to the indication information.

[0165] It is worth noting that the above information (time information Ta threshold, time offset T_offset, number of times information Num threshold, indication information of resource release) can be configured to the first device 110 in at least one of the following ways: 1. sending the information through the SIB message; 2. sending the information through the multicast message; 3. sending the information through the RRC message. In some embodiments, the above release rule is also suitable for the release of the first device 110 level specific resource of the environmental Internet of Things small data transmission.

[0166] In some examples, the above release rule is also suitable for the release of the UE level specific resource of the AIoT SDT.

[0167] In some embodiments, the method further comprises sending the use of the shared resource for transmitting the environmental Internet of Things related data or signaling over the environmental Internet of Things air interface, and the use of the shared resource is represented by the indication information of the shared resource for transmitting the environmental Internet of Things related data or signaling, wherein the indication information includes at least one bit indicating the use of the shared resource for transmitting the environmental Internet of Things related data or signaling or a resource use number indicating the use of the shared resource for transmitting the environmental Internet of Things related data or signaling.

[0168] In some embodiments, the method further comprises receiving the indication information of the shared resource for transmitting the environmental Internet of Things related data or signaling, and reporting the indication information, wherein the indication information is used to indicate the use of the shared resource for transmitting the environmental Internet of Things related data or signaling.

[0169] In particular, the indication information and / or time information window of resource usage for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT can be configured to the plurality of first devices 110 through system messages, paging messages, RRC messages, and notably, the indication information and / or time information window of resource usage for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT can also be sent through separate configuration information, such as the first configuration information. In this way, the first device 110 can release the selected at least one resource according to the indication information and / or time information window of resource usage for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT in the configuration information, or the third device 130 reconfigures the selected at least one resource.

[0170] An example flowchart is shown in FIG. 8, and the flow includes:

[0171] Step H801: The third device 130 sends configuration information to the first device 110, and the configuration information includes at least one of the following: 1. Indication information of shared resource usage for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT: This information is used to indicate the usage of shared resources for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT. After receiving the indication information, the first device 110 reports the use of AIoT-Uu shared resources for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT to the first device 110. 2. Time information window: This information is used to indicate the usage of shared resources for transmitting data or signaling related to the environmental IoT over the air interface of the environmental IoT within the defined time window, wherein the configuration information can be carried by system messages, paging messages, and RRC messages.

[0172] Step H802: The first device 110 can report to the third device 130 the usage of the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface. The usage of the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface is represented by the shared resource indication information for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface, and at least one of the following methods is used: Method 1. 2 bits are used to indicate the usage of the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface, such as 00 indicating that the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface is not used, and 01 indicating that the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface is used. Optionally, usage frequency and usage infrequency can also be defined. Method 2. The resource usage times are used to indicate the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface, such as 5 times indicating that the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface is used 5 times. It is worth noting that the information of Method 1 and / or Method 2 can be combined with the time information window. Assuming that the duration of the time information window is 20 minutes, the first device 110 will count the usage of the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface within the 20 minutes. Further, the configuration information can be sent to the third device 130 through RRC messages, medium access control control elements (MAC CEs), user control information (UCIs), or physical random access channels (PRACHs).

[0173] Step H803: The third device 130 determines whether the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface needs to be released according to the collected indication information of the usage of the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface sent by different first devices 110, and further adjusts the configuration of the shared resource for transmitting the data or signaling related to the environmental IoT over the environmental IoT air interface.

[0174] Optionally, it also includes step H804: sending the second information for releasing the resource.

[0175] In summary, due to the long time of non-use of the configured resources, the resources are wasted. Through the above method, the resources can be released in some cases, and the resource utilization rate can be improved. The release of resources can be triggered by the third device 130 or by the first device 110.

[0176] As an example, a possible flowchart of a method of wireless communication is shown in FIG. 9, and the flow includes:

[0177] Step H900: The first device 110 receives one or more sets of AIoT shared resource configurations, the AIoT shared resources including shared resources on the environmental Internet of Things air interface for transmitting environmental Internet of Things related data or signaling, and / or shared resources on the wireless cellular network air interface for carrying environmental Internet of Things small data transmission.

[0178] Step H901b: The first device 110 receives second information for releasing shared resources sent by the third device 130, and there are two optional ways:

[0179] Way 1: The network side directly configures the second information for releasing shared resources. Specifically, the first device 110 can be instructed to release the shared resources in an implicit manner, i.e., the first device 110 receives a configuration release rule, and automatically releases the resources after evaluation by the first device 110, the shared resource release message carrying time information Ta threshold or number information Num threshold; in addition, the release rule can also be predefined; or the first device 110 can be instructed to release the shared resources in an explicit manner, i.e., the shared resource release message carries a release indication IE. This way is suitable for releasing shared resource information on the wireless cellular network air interface for carrying environmental Internet of Things small data transmission, and is also suitable for releasing shared resource information on the environmental Internet of Things air interface for transmitting environmental Internet of Things related data or signaling.

[0180] Manner 2: Step H901a: The network side sends second information based on the first device 110 reporting the use of shared resources. Specifically, the third device 130 determines whether the shared resources used for transmitting environment Internet of Things related data or signaling on the environment Internet of Things air interface need to be released according to the indication information collected by the third device 130 from different first devices 110 about the use of shared resources for transmitting environment Internet of Things related data or signaling on the environment Internet of Things air interface. Optionally, the third device 130 can also adjust the configuration of the shared resources used for transmitting environment Internet of Things related data or signaling on the environment Internet of Things air interface (i.e., reallocate resources). The third device 130 determines whether the shared resources used for transmitting environment Internet of Things related data or signaling on the environment Internet of Things air interface need to be released according to the indication information collected by the third device 130 from different first devices 110 about the use of shared resources for transmitting environment Internet of Things related data or signaling on the environment Internet of Things air interface. Optionally, the third device 130 can also adjust the configuration of the shared resources used for transmitting environment Internet of Things related data or signaling on the environment Internet of Things air interface.

[0181] Step H902: The first device 110 automatically releases the AIoT shared resources according to the second information.

[0182] In some embodiments, for the case where the resources are shared resources used for carrying environment Internet of Things small data transmission on the wireless cellular network air interface, the environment Internet of Things small data transmission capability information is sent before the configuration information.

[0183] Specifically, the first device 110 can support environment Internet of Things service transmission in the RRC Inactive state (RRC Inactive), which is referred to as environment Internet of Things small data transmission capability. Specifically, the first device 110 can support random access based SDT transmission, pre-configuration based SDT transmission, and SRB based SDT transmission. Specifically, the first device 110 can have any one of the following environment Internet of Things small data transmission capabilities, which are sent to the network through the first device 110 capability reporting message. Examples are as follows:

[0184] Wherein: the definition of each AIoT-SDT capability IE is as follows:

[0185] ra-SDT-AIoT: used to indicate that the first device 110 supports small data packet transmission based on random access when performing AIoT small data transmission, including 2-step random access and / or 4-step random access.

[0186] cg-SDT-AIoT: used to indicate that the first device 110 supports small data packet transmission based on CG when performing AIoT small data transmission.

[0187] srb-SDT-AIoT: used to indicate that the first device 110 supports small data packet transmission based on SRB when performing AIoT small data transmission, and the SRB can be SRB2.

[0188] Or SRB4, or AIoT dedicated SRB bearer.

[0189] It is worth noting that the aforementioned request information can also be carried in the AIoT-SDT capability information.
