Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a method and device for determining a wireless frame structure, and a storage medium. Background Art

[0002] Communication and perception fusion (abbreviated as synaesthesia fusion) is an important technology for future communication networks. Communication refers to the transmission of information between two or more points, and perception refers to the detection of parameters of the physical environment. Synaesthesia fusion can greatly reuse the frequency and site resources of communication and perception, realize the unified design of communication and perception functions, and realize the perception function while transmitting information, thereby improving the overall performance and business capabilities.

[0003] However, synaesthesia fusion is still in the technical definition stage. In the time division duplexing (TDD) communication network, how to allocate uplink and downlink channel resources (such as subframes in wireless frames) so that user terminals can smoothly communicate synaesthesia fusion data (communication data and perception data) with access network equipment (such as base stations) is an urgent problem to be solved. Summary of the invention

[0004] The present application provides a method and device for determining a wireless frame structure, and a storage medium, which can adjust the wireless frame structure according to the uplink and downlink data requirements of perception services and communication services to reasonably allocate uplink and downlink channel resources, thereby ensuring normal communication of inter-sensory fusion data between user terminals and access network equipment.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a method for determining a wireless frame structure is provided, which is applied to a perception terminal, and the perception terminal is a user terminal with a perception function, the method comprising: obtaining perception requirements; the perception requirements are used to instruct the perception terminal to perform a perception service; obtaining the perception service requirement data of the perception terminal in the next unit time; according to the perception service requirement data, determining the subframe requirement value of the perception terminal in the next unit time; the subframe requirement value includes the perception subframe requirement value of the perception service and / or the communication subframe requirement value of the communication service; according to the subframe requirement value, determining the communication subframe and the perception subframe in the wireless frame currently used by the perception terminal to obtain a target wireless frame structure; wherein the communication subframe is used to transmit data of the communication service, and the perception subframe is used to transmit data of the perception service.

[0007] Based on the above technical solution, when a certain perception terminal needs to determine the frame structure of the wireless frame used for communicating interawareness fusion data (uplink and downlink data of communication services and uplink and downlink data of perception services) with the corresponding access network device in the next unit time. In this application, for the perception terminal, because the structure of the existing wireless frame needs to be changed only when there is a perception demand, the perception terminal will obtain the interawareness service demand data for the next unit time after obtaining the perception demand.

[0008] The synaesthesia service demand data includes the uplink and downlink demand of the communication service in the next unit time (uplink communication data demand and downlink communication data demand) and the uplink and downlink demand of the perception service in the next unit time (uplink perception data demand and downlink perception data demand). The synaesthesia service demand data can accurately reflect the uplink and downlink demand of the communication service and perception service of the perception terminal in the next unit time.

[0009] Based on this, the perception terminal can determine the number of uplink and downlink subframes required by the communication service and / or the number of uplink and downlink subframes required by the perception service in the next unit time, that is, the subframe requirement value, according to the inter-awareness service demand number. The subframe requirement value includes the perception subframe requirement value and / or the communication subframe requirement value; the perception subframe requirement value includes the uplink perception subframe requirement value and the downlink perception subframe requirement value of the perception service; the communication subframe requirement value includes the uplink communication subframe requirement value and the downlink communication subframe requirement value of the communication service. Afterwards, the communication subframe and the perception subframe in the wireless frame currently used by the perception terminal can be smoothly determined according to the subframe requirement value to obtain the target wireless frame structure. Afterwards, the perception terminal can communicate the inter-awareness fusion data (uplink and downlink data of the perception service and uplink and downlink data of the communication service) with the corresponding access network equipment according to the target wireless frame structure.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0049] It should also be noted that, in the embodiments of the present application, the terms "of", "corresponding, relevant" and "corresponding" can sometimes be used interchangeably. It should be pointed out that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0050] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0051] Communication and perception fusion (abbreviated as synaesthesia fusion) is an important technology for future communication networks, but it is still in the technical definition stage. In order to facilitate the construction of synaesthesia fusion networks, how to allocate uplink and downlink channel resources (such as subframes in wireless frames) in the existing time division duplexing (TDD) communication network so that user terminals can smoothly communicate synaesthesia fusion data (communication data and perception data) with access network equipment (such as base stations) is an urgent problem to be solved.

[0052] In an embodiment of the present application, the business data of the perception service may specifically be acquired by various types of user terminals (such as mobile phones, smart wearable devices, etc.). The business data of the perception service (which may be referred to as perception data) may include contact perception data and non-contact perception data. Among them, the contact perception data includes body temperature, heartbeat, blood pressure, etc. The non-contact perception data requires the terminal to actively send a signal to the surrounding environment for sensing the surrounding environment. The signal will be reflected after encountering an obstacle. At this time, the terminal can receive the echo signal returned by the transmission of the signal, and obtain the statistical data, such as: image, ambient temperature, ambient humidity, location information, altitude, etc.

[0053] In response to the above problems, an embodiment of the present application provides a method for determining a wireless frame structure, which is applied to a perception terminal with a perception function. When the perception terminal implements this solution, the number of subframes required for the perception service and / or communication service, that is, the subframe demand value, can be determined based on its inter-perception service demand data in the next unit time, that is, the uplink and downlink demands of the perception service and the communication service in the next unit time. Afterwards, the subframe demand value can be used to determine which subframes in the wireless frame currently used by the perception terminal should be communication subframes for transmitting communication data, and which subframes should be perception subframes for transmitting perception data, so as to obtain a target wireless frame structure. Thereby, the perception terminal can use the target wireless frame structure to perform data communication of the perception service and the communication service with the access network device.

[0054] In the embodiment of the present application, the method for determining the radio frame structure can be used in the following cases: Figure 1 In the system architecture shown. For example, refer to Figure 1 As shown, the system may include: a perception terminal 01, an access network device 02, a perception server 03, and a core network 04. The user terminal 01 and the access network device 02, the access network device 02 and the perception server 03, the perception server 03 and the core network 04, and the access network device 02 and the core network 04 all communicate in a wired or wireless manner.

[0055] The perception server 03 can be a separate server, or a network element in the core network 04 (for example, AMF (access and mobility management function) or UPF (userport function)) or a part of a network element, and this application does not impose specific restrictions on this. The perception terminal 01 is a terminal that can perform communication services and perception services.

[0056] In the embodiment of the present application, the access network device 02 may be a base station or a base station controller for wireless communication, etc. In the embodiment of the present application, the base station may be a base station (base transceiverstation, BTS) in a global system for mobile communication (GSM), a base station (node ​​B, NB) in code division multiple access (CDMA), a base station (evolved Node B, eNB) in a long term evolution (LTE), an eNB in ​​the internet of things (IoT) or narrow band-interne tofthings (NB-IoT), a base station in a future 5G mobile communication network or a future evolved public land mobile network (PLMN), and the embodiment of the present application does not impose any restrictions on this.

[0057] In the embodiment of the present application, the perception terminal 01 is used to provide voice and / or data connectivity services to the user. The perception terminal 01 also has a perception function and can be used to perform perception tasks, such as detecting user physiological characteristics, positioning, etc. The perception terminal can have different names, such as user equipment (UE), access terminal, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, vehicle user equipment, terminal agent or terminal device, etc. Optionally, the terminal can be various handheld devices, vehicle-mounted devices, wearable devices, and computers with communication functions, and the embodiment of the present application does not impose any restrictions on this. For example, the handheld device can be a smart phone. The vehicle-mounted device can be a vehicle-mounted navigation system. The wearable device can be a smart bracelet. The computer can be a personal digital assistant (PDA) computer, a tablet computer, and a laptop computer.

[0058] For example, refer to Figure 2 As shown, in order to implement the technical solution provided by the embodiment of the present application, the user terminal 01 may include six modules: a perception trigger signaling receiving module 011, a perception module 012, a communication and perception data frame structure allocation module 013, an intra-frame structure signaling generation module 014, a data encapsulation and sending module 015, and a data receiving module 016.

[0059] The sensing trigger signaling receiving module 011 is used to receive the sensing trigger signaling sent from the access network device 01 and obtain the sensing requirement carried in the signaling, and at the same time, notify the sensing module 012 to start sensing and perform the sensing service corresponding to the sensing requirement.

[0060] The perception module 012 will start the perception function when the perception trigger signaling parsing module 011 receives the perception trigger signaling, or when the perception terminal receives the perception operation implemented by the user and needs to perform perception, and start the perception task corresponding to the corresponding perception service in the next unit time, such as imaging or data collection of the surrounding environment. In this application, there can be multiple perception services.

[0061] The communication and perception data frame structure allocation module 013 is used to determine which subframes in the currently used wireless frame can be communication subframes for transmitting communication service data and which subframes can be perception subframes for transmitting perception service data after determining the perception service demand data of the perception terminal 01 in the next unit time, that is, to clarify the frame structure of the wireless frame and obtain the target wireless frame structure ultimately used in the next unit time.

[0062] It should be noted that the communication service mentioned in this application refers to the communication service, and the perception service refers to the perception service. For example, the uplink communication demand of the communication service of a user terminal in the next unit time specifically refers to the total uplink communication demand of all communication services of the user terminal in the next unit time. The rest of the similar content is the same and will not be repeated later.

[0063] In the present application, the target wireless frame structure determined by the communication and perception data frame structure allocation module 013 can be represented by the relevant indication information of which specific subframes in the wireless frame currently used by the perception terminal are perception subframes or communication subframes. Because there are only three types of subframes in the wireless frame: uplink subframes, downlink subframes and special subframes, among which special subframes are not distinguished for perception or communication, after determining which subframes are perception subframes, the remaining subframes except special subframes are communication subframes. Therefore, in practice, the target frame structure can be represented by the relevant indication information of which specific subframes in the wireless frame are certain subframes. In addition, the indication information indicating a certain subframe in the wireless frame can be the order obtained by sorting all subframes in chronological order.

[0064] For example, a 2.5 ms double-periodic radio frame is used as the radio frame currently used by the sensing terminal 01 in this application, and the radio frame A corresponding to a certain target radio frame structure determined by the sensing terminal 01 can be as follows: Figure 3 As shown in , D is a downlink subframe, S is a special subframe, and U is an uplink subframe. Figure 3 As shown, except for the special subframes, the 7th subframe (specifically the downlink subframe) and the 10th subframe (specifically the uplink subframe) from left to right (i.e., time order) in the wireless frame A are sensing subframes, and the rest are communication subframes. At this time, the indication information of the target frame structure corresponding to the wireless frame A can be:

[0065] Downlink sensing subframe: 7

[0066] Uplink sensing subframe: 10

[0067] Wherein, 7 and 10 represent the order or position of the subframes of the corresponding category in the infinite frame A.

[0068] Of course, in practice, the target frame structure may be indicated by the order or position of the communication subframe in the infinite frame, or the target frame structure may be indicated by the order or position of the communication subframe and the perception subframe in the infinite frame, or any other feasible method.

[0069] The intra-frame structure signaling generation module 014 is used to generate a perception configuration signaling based on the target wireless frame structure determined by the communication and perception data intra-frame structure allocation module 013, and send it to the access network device 0. The perception configuration signaling may carry indication information indicating the target wireless frame structure, so that the access network device can communicate the inter-sensory fusion data (uplink and downlink data of the communication service and uplink and downlink data of the perception service) with the perception terminal 01 according to the target wireless frame structure in the next unit time.

[0070] The data encapsulation and sending module 015 is used to encode and encapsulate the uplink communication data of the communication service and the uplink perception data of the perception service in the next unit time according to the target wireless frame structure determined by the communication and perception data frame structure allocation module 013 when receiving the confirmation information sent by the access network device 02, and send them to the access network device 02. The confirmation information is used to indicate that the access network device 02 has successfully received the perception configuration signaling reported by the perception terminal 01.

[0071] In some embodiments, the perception configuration signaling (carrying the indication information indicating the target wireless frame structure in this application) sent by the intra-frame structure signaling generation module 014 to the access network device can also be sent to the access network device at the beginning of the next unit time, and the data encapsulation sending module 015 also starts to send the encapsulated uplink data to the access network device 02. Afterwards, the data encapsulation sending module 015 can continue to send uplink data after receiving the confirmation information from the access network device 02. Of course, the defect of this method compared to the aforementioned confirmation information and perception configuration signaling sending method is that it will cause the perception terminal 01 to send less data in the next unit time (consuming the time waiting for the confirmation information).

[0072] The data receiving module 016 is used to receive downlink data from the access network device 02, and parse the downlink data according to the target wireless frame structure determined by the communication and perception data frame structure allocation module 013 to obtain the downlink communication data belonging to the communication service and the downlink perception data belonging to the perception service.

[0073] For example, refer to Figure 2 As shown, in order to implement the technical solution provided by the embodiment of the present application, the access network device 02 may include five modules: a perception trigger signaling transceiver module 021, a perception configuration signaling receiving module 022, a data category extraction module 023, a terminal upload data receiving module 024, and a perception data and communication data extraction and sending module 025.

[0074] Among them, the perception trigger signaling transceiver module 021 is used to receive the perception service request from the perception server 03, extract the perception demand therein and determine the corresponding perception terminal. Then generate the corresponding perception trigger signaling and send it to the corresponding perception terminal. The perception trigger signaling may include the perception demand. Specifically, the perception trigger signaling transceiver module 021 can send the perception trigger signaling to the perception terminal 01 through the physical downlink control channel (physical downlink control channel, PDCCH).

[0075] Exemplarily, part of the content of the perception trigger signaling is as follows:

[0076] Signaling Type: sense trigger

[0077] UE ID (user terminal identification code): 1234

[0078] Among them, the user terminal identification code is the identity identification code of the perception terminal.

[0079] The perception configuration signaling receiving module 022 is used to receive the perception configuration signaling sent by the perception terminal 01, and the perception configuration signaling may carry indication information indicating the target frame structure determined by the perception terminal 01. The perception configuration signaling receiving module 022 is also used to store the target frame structure indicated by the indication information of all perception terminals 01 received by itself and the association relationship between the corresponding perception terminals 01 and the corresponding perception terminals 01 in a database for subsequent extraction by the data category extraction module 023. The database may specifically store the association relationship between the identity document (ID) of the perception terminal 01 and the target wireless frame structure matched with it.

[0080] For example, taking the case where the perception configuration signaling receiving module 022 receives indication information indicating the target frame structure sent by four perception terminals, and uses the order or position of the perception subframe in the infinite frame as indication information to indicate the target frame structure, the association relationship stored in the database can be shown in Table 1 below.

[0081] Table 1-Frame structure configuration table

[0082]

[0083] Among them, the number corresponding to the uplink sensing subframe is the order or position of the subframes in the wireless frame that are uplink sensing subframes after being sorted in time order, and the same applies to the downlink sensing subframes. The uplink sensing subframe is the uplink subframe used to transmit uplink data of the sensing service, and the downlink sensing subframe is the downlink subframe used to transmit downlink data of the sensing service. If the uplink sensing subframe of a sensing terminal does not exist, there is no corresponding value in Table 1, which can be recorded as "-".

[0084] The above example only takes the order or position of the sensing subframe in the infinite frame as indication information to indicate the target frame structure. In practice, if there are other feasible methods, the storage format is similar to the above Table 1. This application does not make specific restrictions on this.

[0085] The data category extraction module 023 is used to determine the corresponding target wireless frame structure from the database of the association relationship between the target wireless frame structure and the perception terminal stored in the perception configuration signaling receiving module 022 according to the identity identification code ID of the perception terminal 01 in the uplink data received by the terminal upload data receiving module 024.

[0086] The terminal upload data receiving module 024 is used to receive the uplink data sent by the user terminal 01 in the next unit time, and send a reception success instruction to the user terminal 01 after successful reception.

[0087] The sensing data and communication data extraction and sending module 025 is used to parse the uplink data received by the terminal upload data receiving module 024 according to the target wireless frame structure determined by the data category extraction module 023, so as to obtain the uplink sensing data belonging to the sensing service and the uplink communication data belonging to the notification service. After that, the uplink sensing data is sent to the sensing server 03 for processing the data of the sensing service, and the uplink communication data is sent to the network element or device for processing the data of the communication service in the core network 04.

[0088] The data category extraction module 023 is also used to determine the corresponding target radio frame structure from the database of the association relationship between the target radio frame structure and the perception terminal stored in the perception configuration signaling receiving module 022 according to the indication information (e.g., ID) of the perception terminal in the downlink communication data of the communication service issued by the core network 04 or the downlink perception data of the perception service issued by the perception server 03. At this time, the perception data and communication data extraction and sending module 025 is also used to encode and encapsulate the downlink communication data of the communication service issued by the core network 04 and the downlink perception data of the perception service issued by the perception server 03 according to the target radio frame structure determined by the data category extraction module 023 and send them to the corresponding user terminal 01.

[0089] Based on the above Figure 1-Figure 3 The present invention provides a method for determining a wireless frame structure, which is applied to Figure 1 In the system shown in FIG. , take the access network device as the new radio (NR) as an example, refer to Figure 4 As shown, the method includes 401-408:

[0090] 401. The perception terminal obtains the perception requirement.

[0091] The sensing requirement is used to instruct the sensing terminal to perform sensing services.

[0092] In some embodiments, 401 may specifically be that the perception terminal responds to a perception event and obtains a perception request.

[0093] In one achievable manner, the perception event may be a perception operation, which may be performed by a user on the perception terminal, such as turning on a switch of a perception function, or operating the perception terminal to perform a certain perception task. In this case, the perception requirement is used to instruct the perception terminal to perform the perception service corresponding to the perception operation.

[0094] In this case, combined Figure 4 , refer to Figure 5 As shown, step 401 may be 401A:

[0095] 401A. The perception terminal obtains the perception requirement in response to the perception operation.

[0096] In this way, the perception terminal can successfully obtain the perception requirements.

[0097] In another achievable manner, the perception event may be that the perception terminal receives a perception demand from an access network device. Specifically, the access network device may forward the perception demand to the perception terminal after receiving the perception demand from the core network.

[0098] In this case, combined Figure 4 , refer to Figure 6 As shown, step 401 may also include S1-S4, and step 401 may specifically be 401B:

[0099] S1. The core network sends a perception service request to the perception server.

[0100] The awareness service request may be a perception service request sent by a user with awareness requirements to the core network. For example, the user here may be an operator or some specific user, and this application does not impose any specific restrictions on this.

[0101] The perception service request may include a perception requirement, which may indicate at least one perception service that needs to be run, and may specifically include a service category and / or a perception service name of the target perception service. The instruction may also carry relevant parameters of the target perception service, such as the amount of uplink and downlink data required per unit time, etc.

[0102] S2. The perception server receives the perception service request from the core network and sends the perception service request to the NR.

[0103] S3. NR receives the perception service request from the perception server and obtains the perception requirement in the perception service request.

[0104] S4. NR sends a perception trigger instruction to the perception terminal.

[0105] Among them, the perception trigger signaling includes the aforementioned perception requirements.

[0106] Among them, steps S2 and S3 can be implemented by the perception trigger signaling transceiver module 021 in the aforementioned embodiment.

[0107] 401B. The perception terminal receives a perception trigger instruction from the NR, and obtains a perception requirement from the perception trigger instruction.

[0108] In the present application, step 401B may be implemented by the perception trigger signaling receiving module 011 in the aforementioned embodiment.

[0109] In this way, the perception terminal can obtain the perception requirements from the NR in order to obtain the subsequent synaesthesia service demand data.

[0110] 402. The perception terminal obtains synaesthesia service demand data for the next unit time.

[0111] The synaesthesia service demand data includes: uplink communication data demand of communication service, downlink communication data demand of communication service, uplink perception data demand of perception service and downlink perception data demand of perception service.

[0112] 403. The perception terminal determines a subframe requirement value of the perception terminal in the next unit time according to the synaesthesia service requirement data.

[0113] In the present application, for the target frame structure finally determined by the perception terminal, it is necessary to determine which subframes in the wireless frame currently used by the perception terminal belong to communication subframes (including uplink communication subframes and downlink communication subframes) and which belong to perception subframes (including uplink perception subframes and downlink perception subframes). Because in the present application, the subframes in the wireless frame that can be used as communication subframes or perception subframes are determined, and there are only two subframe categories: communication subframes and perception subframes. Therefore, the final target frame structure can be indicated by the order (order after sorting in time sequence) or position of a certain type of subframes in the wireless frame, and the order or position of the available subframes in the wireless frame is another type of subframe; it can also be indicated by the order or position of the two types of subframes in the wireless frame.

[0114] Based on this, in the embodiment of the present application, the subframe requirement value includes the perception subframe requirement value of the perception service and / or the communication subframe requirement value of the communication service. Further, in order to more accurately determine the structure in the wireless frame, the perception subframe requirement value here includes the uplink perception subframe requirement value and the downlink perception subframe requirement value; the communication subframe requirement value includes the uplink communication subframe requirement value and the downlink communication subframe requirement value.

[0115] In some embodiments, in order to obtain the subframe requirement value, combined with Figure 4 , refer to Figure 7 As shown, step 403 may specifically include 4031 and 4032:

[0116] 4031. Determine an uplink target subframe demand value according to an uplink communication data demand, an uplink perception data demand, and the number of uplink subframes in a wireless frame currently used by the perception terminal.

[0117] In one achievable manner, if the subframe requirement value includes a sensing subframe requirement value, the uplink target subframe requirement value is the uplink sensing subframe requirement value. At this time, the uplink sensing subframe requirement value can be calculated according to the following formula (1):

[0118]

[0119] in, is the uplink sensing subframe requirement value; is the demand for uplink communication data; N is the uplink sensing data demand; up is the total number of uplink subframes, that is, the number of uplink subframes in the wireless frame currently used by the sensing terminal, and round() is a rounding function that rounds to the nearest integer.

[0120] At this time, the uplink communication subframe requirement value is the total uplink subframe number minus the uplink sensing subframe requirement value.

[0121] In another achievable manner, if the subframe requirement value includes a communication subframe requirement value, the uplink target subframe requirement value is the uplink communication subframe requirement value. In this case, the uplink communication subframe requirement value can be calculated according to the following formula (2):

[0122]

[0123] in, is the uplink communication subframe requirement value; is the demand for uplink communication data; N is the uplink sensing data demand; up is the total number of uplink subframes, that is, the number of uplink subframes in the wireless frame currently used by the communication terminal.

[0124] At this time, the uplink sensing subframe requirement value is the total uplink subframe number minus the uplink communication subframe requirement value.

[0125] Of course, if the subframe requirement value includes a perception subframe requirement value and a communication subframe requirement value, the uplink perception subframe requirement value and the uplink communication subframe requirement value can be calculated according to the above formula (1) and formula (2).

[0126] 4032. Determine a downlink target subframe demand value according to the downlink communication data demand, the downlink perception data demand, and the number of downlink subframes in the wireless frame currently used by the perception terminal.

[0127] In one achievable manner, if the subframe requirement value includes a sensing subframe requirement value, the downlink target subframe requirement value is the downlink sensing subframe requirement value. At this time, the downlink sensing subframe requirement value can be calculated according to the following formula (3):

[0128]

[0129] in, is the downlink sensing subframe requirement value; The data demand for downlink communication; N is the downlink sensing data demand; down is the total number of downlink subframes, that is, the number of downlink subframes in the wireless frame currently used by the sensing terminal.

[0130] At this time, the downlink communication subframe requirement value is the total downlink subframe number minus the downlink sensing subframe requirement value.

[0131] In another achievable manner, if the subframe requirement value includes a communication subframe requirement value, the downlink target subframe requirement value is the downlink communication subframe requirement value. In this case, the downlink communication subframe requirement value can be calculated according to the following formula (4):

[0132]

[0133] in, is the downlink communication subframe requirement value; The data demand for downlink communication; N is the downlink sensing data demand; down is the total number of downlink subframes, that is, the number of downlink subframes in the wireless frame currently used by the communication terminal.

[0134] At this time, the downlink sensing subframe requirement value is the total downlink subframe number minus the downlink communication subframe requirement value.

[0135] Of course, if the subframe requirement value includes a perception subframe requirement value and a communication subframe requirement value, the downlink perception subframe requirement value and the downlink communication subframe requirement value can be calculated according to the above formula (3) and formula (4).

[0136] Based on the technical solutions corresponding to the above steps 4031 and 4032, the subframe requirement value can be successfully calculated, providing data support for the subsequent determination of the target wireless frame structure.

[0137] 404. The perception terminal determines, according to the subframe requirement value, a communication subframe and a perception subframe in a wireless frame currently used by the perception terminal to obtain a target wireless frame structure.

[0138] Among them, the communication subframe is used to transmit data of communication services, and the perception subframe is used to transmit data of perception services.

[0139] In some embodiments, in order to obtain the subframe requirement value, combined with Figure 4 , refer to Figure 8 As shown, step 404 may specifically include steps 4041-4043:

[0140] 4041. When the subframe requirement value includes the perception subframe requirement value, the perception terminal selects perception subframes one by one from the wireless frames currently used by the perception terminal according to the perception subframe requirement value and in a first preset order.

[0141] The first preset order may be a reverse order of time, but in practice it may also be a time order or any other feasible order.

[0142] For example, refer to Fig. 9 As shown in (a), a 2.5ms double-period radio frame is used as the radio frame currently used by the sensing terminal in this application, and the first preset order is a time reverse order. If the uplink sensing subframe requirement value in the sensing subframe requirement value is 2, and the downlink sensing subframe requirement value is 1. The sensing subframes are selected in the order of time reverse order, then Fig. 9As shown in (b), the 9th and 10th subframes from left to right are uplink sensing subframes, and the 7th subframe is a downlink sensing subframe.

[0143] 4042. When the subframe requirement value includes a communication subframe requirement value, the perception terminal selects communication subframes one by one from the wireless frames currently used by the perception terminal according to the communication subframe requirement value and in a second preset order.

[0144] The second preset order may be a time sequence, or in practice, a reverse time sequence or any other feasible sequence.

[0145] For example, refer to Fig. 9 As shown in (a), a 2.5ms double-period radio frame is used as the radio frame currently used by the sensing terminal in this application, and the second preset order is the time order. If the uplink communication subframe demand value in the communication subframe demand value is 1, and the downlink communication subframe demand value is 4. The communication subframes are selected in the order of time order, then Fig. 9 As shown in (c), the 5th subframe from left to right is the uplink communication subframe, and the 1st, 2nd, 3rd, and 6th subframes are the downlink communication subframes.

[0146] In some embodiments, when the subframe requirement value includes a sensing subframe requirement value and a communication subframe requirement value, in order to facilitate the selection of the communication subframe and the sensing subframe without causing a conflict due to selecting the same subframe, the first preset order and the second preset order are opposite. In this way, the selection of the communication subframe and the sensing subframe will start from the two ends of the wireless frame respectively, and no conflict will occur.

[0147] 4043. The perception terminal determines the target wireless frame structure according to the selection results of the communication subframe and the perception subframe.

[0148] For example, Fig. 9 (b) and Fig. 9 Taking the example shown in (c) as an example, the target wireless frame structure finally determined can be as follows Fig. 9 As shown in (d). Among them, the 9th and 10th subframes from left to right are uplink perception subframes, the 7th subframe is a downlink perception subframe, the 5th subframe is an uplink perception subframe, and the 6th subframe is a downlink perception subframe. Of course, for special subframes in wireless frames, they can be allocated to perception services or communication services according to actual needs. In the case of an uncertain allocation tendency, some or all special subframes can also be used as optional subframes that can be determined as communication subframes or perception subframes. This application does not make specific restrictions on this.

[0149] Based on the above-mentioned technical solutions corresponding to 4041-4043, the corresponding target wireless frame structure can be obtained smoothly according to the previously determined subframe requirement value, so that the subsequent communication of the synaesthesia fusion data between the NR and the perception terminal can proceed smoothly.

[0150] In some embodiments, the above-mentioned step 403 (including steps 4031 and 4032) and step 4044 (including steps 4041A-4043) can be implemented by the communication and perception data frame structure allocation module 013 in the aforementioned embodiments.

[0151] After step 404, the sensing terminal has determined the target wireless frame structure to be used when communicating with NR in the next unit time, and can communicate with NR according to the target wireless frame structure in the next unit time. Further, in order to enable the NR to parse the uplink data from the sensing terminal in time when the sensing terminal communicates with NR in the future. Figure 4 As shown, after step 404, the sensing terminal needs to promptly inform the NR of the indication information indicating the target radio frame structure, so that the NR can promptly and accurately parse the uplink data in the next unit time. That is, step 404 also includes subsequent steps 405-407.

[0152] 405. The perception terminal sends a perception configuration instruction to the NR.

[0153] The perception configuration instruction may carry indication information indicating the target wireless frame structure. In this way, after receiving the perception configuration instruction, the NR can know what coding and encapsulation method the perception terminal will use to send uplink data in the future, which is convenient for parsing; at the same time, it can also know what coding and encapsulation method will be used to send downlink data to the perception terminal in the future.

[0154] For example, Fig. 9 Taking the example shown in (d) above, the indication information of the target frame structure is the order or position of the sensing subframe in the infinite frame as an example, the sensing configuration instruction may be as follows:

[0155] Signaling Type: sense configuration

[0156] UE ID (UE ID): 1234

[0157] Sense of uplink (uplink perception subframe): 9, 10

[0158] Sense of downlink (downlink sensing subframe): 7

[0159] In one achievable manner, step 405 may be implemented by the intra-frame structure signaling generation module 014 in the aforementioned embodiment.

[0160] 406. NR receives the perception configuration instruction from the perception terminal and sends confirmation information to the perception terminal.

[0161] The confirmation information is used to indicate that the NR has successfully received the perception configuration instruction.

[0162] In addition, after receiving the perception configuration instruction, the NR will store the association relationship between the perception terminal and the target radio frame structure indicated by the perception configuration instruction, as shown in the above Table 1.

[0163] In one achievable manner, step 406 may be implemented by the perception configuration signaling receiving module 022 in the aforementioned embodiment.

[0164] 407. The sensing terminal receives confirmation information from NR.

[0165] In one achievable manner, step 406 may be implemented by the data encapsulation and sending module 015 in the aforementioned embodiment.

[0166] Based on the technical solutions corresponding to 405-407 above, NR can know the target wireless frame structure determined by the perception terminal before the perception terminal sends uplink data. Afterwards, after receiving the uplink data sent by the perception terminal in the next unit time, the uplink data can be parsed promptly and accurately for corresponding processing. When NR subsequently sends downlink data to the perception terminal, it can also use the target wireless frame structure to encode and encapsulate the downlink perception data and downlink communication data that need to be sent to the perception terminal to obtain downlink data, so that the perception terminal can smoothly parse the downlink data when it receives it.

[0167] In some other embodiments, after step 404, the perception terminal may also send indication information indicating the target wireless frame structure to the NR at the beginning of the next unit time, and the perception terminal encodes and encapsulates the uplink communication service data and the uplink perception service data according to the target wireless frame structure to obtain uplink data, and sends the uplink data to the NR. Afterwards, after receiving the indication information and uplink data from the perception terminal, the NR can parse the uplink data and send confirmation information to the perception terminal, so that the perception terminal continues to send uplink data based on the target wireless frame structure. In this way, the NR and the perception terminal can also communicate smoothly in the next unit time. However, compared with the technical solution corresponding to the aforementioned steps 405-407, because the perception terminal in this solution does not send uplink data during the time waiting for confirmation information from the access network device in the next unit time, this solution may reduce the amount of data sent by the perception terminal in the next unit time.

[0168] 408. The perception terminal uses the target wireless frame structure to perform data communication of the perception service and the communication service with the NR in the next unit time.

[0169] In one possible way, combining Figure 4 , refer to Fig.10 As shown, step 408 may specifically include steps 4081-4087:

[0170] 4081. The perception terminal encodes and encapsulates the uplink perception data belonging to the perception service and the uplink communication data belonging to the communication service using the target wireless frame structure to obtain uplink data, and sends the uplink data to the NR.

[0171] In one achievable manner, step 4081 may be implemented by the data encapsulation and sending module 015 in the aforementioned embodiment.

[0172] 4082. NR receives uplink data from the perception terminal, and obtains uplink perception data belonging to the perception service and uplink communication data belonging to the communication service in the uplink data according to the target wireless frame structure.

[0173] Specifically, after receiving the uplink data from the perception terminal, the NR first searches the subframe database for the target radio frame structure corresponding to the perception terminal according to the information indicating the perception terminal (e.g., the ID of the perception terminal) carried therein. After that, the NR parses the uplink data according to the target radio frame structure to obtain the uplink perception data and the uplink communication data.

[0174] In one achievable manner, step 4082 may be implemented by the data category extraction module 023 and the terminal uploaded data receiving module 024 in the aforementioned embodiment.

[0175] 4083. NR sends the uplink perception data in the parsed uplink data to the perception server.

[0176] 4084. NR sends the uplink communication data in the parsed uplink data to the core network.

[0177] In one achievable manner, steps 4083 and 4084 may be implemented by the perception data and communication data extraction and sending module 025 in the aforementioned embodiment.

[0178] 4085. NR receives downlink perception data corresponding to the perception terminal from the perception server and downlink communication data corresponding to the perception terminal from the core network.

[0179] 4086. NR encodes and encapsulates the downlink perception data and the downlink communication data according to the target wireless frame structure to obtain downlink data, and sends the downlink data to the perception terminal.

[0180] In one achievable manner, steps 4083-4086 may be implemented by the perception data and communication data extraction and sending module 025 in the aforementioned embodiment.

[0181] 4087. The perception terminal receives downlink data from the NR, and performs corresponding processing after parsing the downlink data according to the target wireless frame structure to obtain downlink perception data and downlink communication data.

[0182] In one achievable manner, step 4087 may be implemented by the data receiving module 016 in the aforementioned embodiment.

[0183] It should be noted that there is no necessary order between steps 4081-4084 and steps 4085-4087. Fig.10 This is only an example, the specific order depends on the actual situation and this application does not make any specific limitations.

[0184] Based on the technical solution provided by the present application, a certain perception terminal needs to determine the frame structure of the wireless frame used for communicating interawareness fusion data (uplink and downlink data of communication services and uplink and downlink data of perception services) with the corresponding access network device in the next unit time. In the present application, for the perception terminal, because the structure of the existing wireless frame needs to be changed only when there is a perception demand, the perception terminal will obtain the interawareness service demand data for the next unit time after obtaining the perception demand. Among them, the interawareness service demand data includes the uplink and downlink demand of the communication service in the next unit time (uplink communication data demand and downlink communication data demand) and the uplink and downlink demand of the perception service in the next unit time (uplink perception data demand and downlink perception data demand). The interawareness service demand data can accurately reflect the uplink and downlink demands of the communication service and the perception service of the perception terminal in the next unit time.

[0185] Based on this, the perception terminal can determine the number of uplink and downlink subframes required by the communication service and / or the number of uplink and downlink subframes required by the perception service in the next unit time, that is, the subframe requirement value, according to the inter-awareness service demand number. The subframe requirement value includes the perception subframe requirement value and / or the communication subframe requirement value; the perception subframe requirement value includes the uplink perception subframe requirement value and the downlink perception subframe requirement value of the perception service; the communication subframe requirement value includes the uplink communication subframe requirement value and the downlink communication subframe requirement value of the communication service. Afterwards, the communication subframe and the perception subframe in the wireless frame currently used by the perception terminal can be smoothly determined according to the subframe requirement value to obtain the target wireless frame structure. Afterwards, the perception terminal can communicate the inter-awareness fusion data (uplink and downlink data of the perception service and uplink and downlink data of the communication service) with the corresponding access network equipment according to the target wireless frame structure.

[0186] It can be seen that in the technical solution provided by the present application, the perception terminal can determine the uplink and downlink subframes required by the communication service and the perception service, that is, the communication subframe and the perception subframe, according to the uplink and downlink data that it needs to communicate in the next unit time, and then determine the frame structure of the wireless frame currently used by the perception terminal and the access network device in the next unit time, so that the perception terminal and the access network device can communicate smoothly. Therefore, this technical solution solves the problem of how to determine the appropriate wireless frame structure based on the existing time division duplex network architecture to reasonably allocate uplink and downlink channel resources, so that the user terminal and the access network device can smoothly communicate the inter-sensory fusion data.

[0187] The embodiment of the present application can divide the functional modules of the wireless frame structure determination device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0188] When functional modules are used for division, refer to Fig.11 As shown, the present application also provides a wireless frame structure determination device applied to a perception terminal with a perception function. The device may include: an acquisition module 51, a determination module 52, a processing module 53 and a sending module 54. These four modules are used together to only realize the functions of the perception trigger signaling receiving module 011, the perception module 012, the communication and perception data frame structure allocation module 013, the frame structure signaling generation module 014, the data encapsulation sending module 015 and the data receiving module 016 in the aforementioned embodiment, that is, to execute the wireless frame structure determination method provided in the aforementioned embodiment.

[0189] In combination with the wireless frame structure determination method provided in the foregoing embodiment, the acquisition module 51 is used to execute step 401 (including step 401A or step 401B), step 402 and step 407; the determination module 52 is used to execute step 403 (including step 4031 and step 4032); the processing module 53 is used to execute step 404 (including steps 4041-4043) and step 408; and the sending module 54 is used to execute step 405.

[0190] Specifically, the acquisition module 51 is used to obtain perception requirements; the perception requirements are used to instruct the perception terminal to perform perception services; the acquisition module 51 is also used to obtain the synaesthesia service requirement data of the perception terminal in the next unit time; the determination module 52 is used to determine the subframe requirement value of the perception terminal in the next unit time according to the synaesthesia service requirement data obtained by the acquisition module 51; the subframe requirement value includes the perception subframe requirement value of the perception service and / or the communication subframe requirement value of the communication service; the processing module 53 is used to determine the communication subframe and the perception subframe in the wireless frame currently used by the perception terminal according to the subframe requirement value determined by the determination module 52, so as to obtain the target wireless frame structure; wherein the communication subframe is used to transmit the data of the communication service, and the perception subframe is used to transmit the data of the perception service.

[0191] Optionally, the acquisition module 51 is specifically used to: acquire a perception demand in response to a perception event; the perception event includes any of the following: a perception operation, and receiving a perception demand from an access network device.

[0192] Optionally, the synaesthesia service demand data includes: the uplink communication data demand of the communication service, the downlink communication data demand of the communication service, the uplink perception data demand of the perception service, and the downlink perception data demand of the perception service; the determination module 52 is specifically used to: determine the uplink target subframe demand value according to the uplink communication data demand, the uplink perception data demand, and the number of uplink subframes in the wireless frame currently used by the perception terminal obtained by the acquisition module 51; determine the downlink target subframe demand value according to the downlink communication data demand, the downlink perception data demand, and the number of downlink subframes in the wireless frame currently used by the perception terminal.

[0193] The sensing subframe requirement value includes an uplink sensing subframe requirement value and a downlink sensing subframe requirement value of the sensing service; the communication subframe requirement value includes an uplink communication subframe requirement value and a downlink communication subframe requirement value of the communication service.

[0194] When the subframe requirement value includes a perception subframe requirement value, the uplink target subframe requirement value includes an uplink perception subframe requirement value, and the downlink target subframe requirement value includes a downlink perception subframe requirement value; when the subframe requirement value includes a communication subframe requirement value, the uplink target subframe requirement value includes an uplink communication subframe requirement value, and the downlink target subframe requirement value includes a downlink communication subframe requirement value.

[0195] Optionally, the processing module 53 is specifically used for: when the subframe requirement value determined by the determination module 52 includes the perception subframe requirement value, according to the perception subframe requirement value, in accordance with a first preset order, selecting perception subframes one by one from the wireless frames currently used by the perception terminal; when the subframe requirement value determined by the determination module 52 includes the communication subframe requirement value, according to the communication subframe requirement value, in accordance with a second preset order, selecting communication subframes one by one from the wireless frames currently used by the perception terminal.
