Radio frame determining method, access network equipment, core network element and user terminal

Technical Field

The present application relates to the field of communications, and in particular, to a method for determining a radio frame, an access network device, a core network element, and a user terminal.

Background

Communication and awareness fusion (referred to as sense of openness fusion for short) is an important technology for future communication networks. Wherein communication is the transmission of information between two or more points, and sensing or detecting parameters of a physical environment. The communication and sensing frequency and station address resources can be greatly multiplexed through sense fusion, unified design of communication and sensing functions is realized, and the sensing functions can be realized while information transmission is carried out, so that the overall performance and business capability are improved.

However, at present, the sense fusion is still in a technology definition stage, and how to allocate uplink and downlink channel resources (e.g. subframes in radio frames) in a communication network of a time division duplex (time division duplexing, TDD) system, so that a user terminal can smoothly communicate sense fusion data (communication data and sensing data) with access network equipment (e.g. a base station) is a problem to be solved.

Disclosure of Invention

The application provides a radio frame determining method, access network equipment, a core network element and a user terminal, which can determine a proper radio frame according to the data requirements of a sensing service and a communication service so as to achieve the purpose of reasonably distributing channel resources and ensure the normal communication of communication sense fusion data between the user terminal and the access network equipment.

In order to achieve the above purpose, the application adopts the following technical scheme:

In a first aspect, a method for determining a radio frame is provided, which is applied to an access network device. The method comprises the following steps: acquiring total general sense business demand data; the total sense business requirement data comprises: a sum of communication data demands of communication services of at least one user terminal in a coverage area of the access network device in a next unit time and a sum of perception data demands of perception services of the at least one user terminal in the next unit time; calculating a first communication subframe requirement value and a first perception subframe requirement value according to the total communication service requirement data under the condition that the distance between the access network equipment and the adjacent access network equipment is larger than a preset threshold value; determining a first wireless frame according to the first communication subframe requirement value and the first perception subframe requirement value; and sending first indication information for indicating the first wireless frame to the user terminal so that the user terminal can use the first wireless frame to perform data communication of a sensing service and a communication service with the access network equipment.

Based on the above technical solution, in a case where an access network device needs to determine a radio frame used for communication with user terminals in its coverage area in the next unit time (uplink and downlink data of a communication service and uplink and downlink data of a sensing service). In the present application, for the access device, first, the total traffic demand data is acquired. The total traffic data may include the sum of the traffic data demands of the traffic of at least one user terminal in its coverage area at the next unit time and the sum of the perceived traffic data demands. Because if coverage areas of two access network devices (for example, base stations) overlap and radio frames with different structures are used, in the overlapping area, there may be a need to perform downlink data transmission on one of two channels with the same frequency band at a certain moment, and the other need to perform uplink data transmission, at this moment, the two channels interfere with each other, so that the data transmission cannot be performed normally, and user experience is seriously affected. Based on this, the access network device determines the radio frame again in the case that the distance between the access network device and the adjacent access network device is larger than the preset threshold value.

Specifically, the access network device determines the subframe requirements of the communication service and the sensing service of the user terminal in the coverage area of the access network device in the next unit time according to the total sensing service requirement data. I.e. a first communication subframe requirement value and a first perceptual subframe requirement value are calculated. Thereafter, a suitable first radio frame may be determined based on the calculated first communication subframe requirement value and the first perceptual subframe requirement value. And finally, sending first indication information for indicating the first radio frame to the user terminal, so that the user terminal uses the first radio frame to carry out data communication of the sensing service and the communication service with the access network equipment in the next unit time.

In the technical scheme provided by the application, the access network equipment can combine the communication data and the perceived data required by at least one user terminal in the coverage area of the access network equipment in the next unit time, determine the number of subframes required by the communication service and the number of subframes required by the perceived service, and further determine the wireless frame suitable for the access network equipment and the user terminal to communicate in the next unit time. Therefore, the technical scheme solves the problem of how to determine a proper radio frame to reasonably allocate uplink and downlink channel resources on the basis of the network architecture of the existing time division duplex system, so that the user terminal and the access network equipment can smoothly communicate the communication sense fusion data.

In a second aspect, a radio frame determination method is provided, which is applied to a core network element. The method comprises the following steps: receiving total sensory service requirement data from at least one access network device; the total sense business requirement data comprises: a sum of communication data demands of communication services of at least one user terminal in a coverage area of the access network device in a next unit time and a sum of perception data demands of perception services of the at least one user terminal in the next unit time; calculating a second communication subframe requirement value and a second perception subframe requirement value according to all the total communication service requirement data; determining a second radio frame according to the second communication subframe requirement value and the second perception subframe requirement value; and sending second indication information for indicating the second wireless frame to the access network equipment, so that the access network equipment sends third indication information for indicating the second wireless frame to the user terminal corresponding to the total general sense service requirement data of the access network equipment.

Based on the above technical solution, in the case that the core network element needs to determine a radio frame used for communication between at least one access network device covered and controlled by the core network element and a user terminal covered by the core network element (communication requirement data of a communication service and perception requirement data of a perception service) in the next unit time. In the present application, for the core network element, first, total traffic demand data of at least one access network device is obtained. The total traffic data may then include a sum of traffic data requirements of traffic of at least one user terminal in a next unit time and a sum of perceived traffic data requirements of the perceived traffic within a coverage area of the access network device. And then, the core network element determines the subframe requirements of the communication service and the sensing service of all user terminals in the coverage area of at least one access network device in the next unit time according to all the total sensing service requirement data. I.e. a second communication subframe requirement value and a second perceptual subframe requirement value are calculated. Then, based on the calculated second communication subframe requirement value and the second perceived subframe requirement value, an appropriate second radio frame may be determined. And finally, sending third indication information for indicating the second radio frame to the access network equipment, so that the access network equipment sends the third indication information for indicating the second radio frame to the corresponding user terminal. The access network device can then use the first radio frame to communicate data of the sensing service and the communication service with the corresponding user terminal in the next unit time.

In the technical scheme provided by the application, the core network element can combine the data requirement of at least one user terminal needing to be communicated in the next unit time in the coverage area of at least one access network device managed and controlled by the core network element, determine the subframe number needed by communication service and the subframe number needed by sensing service, and further determine the radio frame suitable for the access network device and the user terminal to be communicated in the next unit time. Therefore, the technical scheme solves the problem of how to determine a proper radio frame to reasonably allocate channel resources on the basis of the network architecture of the existing time division duplex system, so that the user terminal and the access network equipment can smoothly communicate the communication sense fusion data (the communication demand data of the communication service and the perception demand data of the perception service).

Further, when the target core network element determines the radio frame, all relevant access network devices use the same radio frame. Therefore, even if the distance between two adjacent access network devices is smaller and the overlapping coverage area exists, one of the channels with the same frequency band in the overlapping coverage area does not need to carry out downlink data transmission, and the other channel carries out uplink data transmission, so that the problem of mutual interference between the two channels and hard data transmission is solved, and the use experience of a user is ensured.

In a third aspect, a radio frame determining method is provided, which is applied to a user terminal. The method comprises the following steps: transmitting the general sense service demand data of the user terminal in the next unit time to access network equipment accessed by the user terminal; the general sense business requirement data comprises: communication data demand of communication service and perception data demand of perception service; receiving fourth indication information from the access network equipment; the fourth indication information is used for indicating the third wireless frame; and using the third radio frame to perform data communication of the sensing service and the communication service with the access network equipment in the next unit time.

Based on the above technical solution, the user terminal may receive fourth indication information from the access network device for indicating the third radio frame after sending the traffic demand data of the next unit time to the access network device. So that the third radio frame can be used for data communication of the awareness traffic and the communication traffic with the access network device in the next unit time. Because the third radio frame determined by the access network device is determined by combining the traffic demand data reported by the user terminal, the radio frame can meet the data volume demand of the user terminal in the next unit time, and the user terminal can smoothly and fully communicate the traffic fusion data in the next unit time and the access network device. Therefore, the problem that how to determine the frame structure of a proper radio frame on the basis of the existing time division duplex network architecture to reasonably allocate channel resources so that the user terminal and the access network equipment can smoothly communicate the sense fusion data is solved.

Communication and awareness fusion (for short, sense of openness fusion) is an important technology of future communication networks, but it is still in the technology definition stage at present. In order to facilitate the construction of a sense fusion network, how to allocate uplink and downlink channel resources (e.g., subframes in a radio frame) in an existing time division duplex (time division duplexing, TDD) communication network so that a user terminal can smoothly communicate sense fusion data (communication data and sensing data) with access network equipment (e.g., a base station) is a problem to be solved.

The service data of the sensing service (which may be simply referred to as sensing data) may include contact sensing data and non-contact sensing data. Wherein, the sensing data of the contact type comprises body temperature, heartbeat, blood pressure and the like.

In view of the above problems, an embodiment of the present application provides a method for determining a radio frame, which is applied to an access network device or a core network element or a user terminal. The method is implemented by defining a plurality of wireless frames with different frame structures including a sensing subframe and a communication subframe in advance. The sensing subframe is a subframe used for transmitting data of sensing service, and the communication subframe is a subframe used for transmitting data of communication service. When the access network device is implemented, the access network device determines a proper radio frame according to the sum of the uplink sensing data volume of sensing service and the sum of the uplink communication data volume of communication service, which are required to be transmitted by at least one user terminal in the coverage area of the access network device, in the next unit time, and informs the radio frame to the user terminal, so that the user terminal can use the radio frame to perform data communication of sensing service and communication service with the access network device.

In the embodiment of the present application, the radio frame determining method may be used in a system architecture as shown in fig. 1. Illustratively, referring to FIG. 1, the system may include: at least one user terminal 01, at least one access network device 02, a perception server 03, a core network 04 and a target core network element 05.

The target core network element 05 is then a network element in the core network 04 that has the capability of handling data from the access network device. Such as AMF. In a special case of the present application, the sensing server 03 and the target core network element 05 may be the same network element device, i.e. AMF or UPF.

In fig. 1, at least one user terminal 01 is exemplified as including a user terminal 01-1, a user terminal 01-2, a user terminal 01-3, and a user terminal 01-4. In practice more or fewer user terminals may be present. At least one access network device 02 in fig. 1 is exemplified as including an access network device 02-1 and an access network device 02-2. In practice more or fewer access network devices may be present.

In the embodiment of the present application, the user terminal 01 is used for providing voice and/or data connectivity services to a user. The user terminal 01 may also be used to perform sensing tasks such as detecting physiological characteristics of the user, positioning, etc. The user terminals may be variously named, for example, user Equipment (UE), access terminals, terminal units, terminal stations, mobile stations, remote terminals, mobile devices, wireless communication devices, vehicle user equipment, terminal agents or end devices, etc. Optionally, the terminal may be a handheld device, an in-vehicle device, a wearable device, or a computer with a communication function, which is not limited in any way in the embodiment of the present application. For example, the handheld device may be a smart phone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a Personal Digital Assistant (PDA) computer, a tablet computer, or a laptop computer (laptop computer).

For example, referring to fig. 2, in order to implement the technical solution provided by the embodiment of the present application, the access network device 02 may include eight modules: the device comprises a perception triggering signaling receiving module 021, a frame structure judging device selecting module 022, a frame structure judging and transmitting module 023, a terminal uploading data receiving module 024, a perception data and communication data extracting and transmitting module 025, a passsense contour information transmitting module 026, a passsense frame structure receiving module 027 and a passsense frame structure transmitting module 028.

Wherein the sensing trigger signaling receiving module 021 is configured to receive a sensing trigger signaling from at least one ue to obtain a communication data requirement of a communication service of the at least one ue in a next unit time. The communication data demand includes an upstream communication data demand and a downstream communication data demand, and a perceived data demand for perceived traffic. The perceived data demand includes an upstream perceived data demand and a downstream perceived data demand. Wherein the user terminal may report the sensing trigger signaling through a physical uplink control channel (physical uplink control channel, PUCCH). In general, at least one user terminal may refer to all user terminals that need to perform a awareness service and/or a communication service within the coverage area of the access network device 02.

Illustratively, the perceived trigger signaling may be as follows:

SIGNALING TYPE (signalling type): SENSE TRIGGER (perception trigger)

UE ID (user terminal identity): 1234

Tele of downlink (downstream traffic data demand of traffic): 10 (Mbps)

Sense of uplink (upstream perceived data demand of traffic): 5 (Mbps)

Sense of downlink (downstream perceived data demand of traffic): 3 (Mbps)

After the sensing trigger signaling receiving module 021 receives sensing signaling sent by a plurality of user terminals, the acquired relevant data of the plurality of user terminals can be shown in the following table 1.

TABLE 1

It should be noted that, in the present application, the communication service refers to a service such as a communication service, and the sensing service refers to a service such as a sensing service. For example, the uplink communication demand of a certain user terminal in the communication service of the next unit time, and specifically refers to the total uplink communication demand of all the communication services of the user terminal in the next unit time. The rest of the similar contents are the same and are not described in detail later.

The frame structure decision device selecting module 022 is configured to query the distance condition between the access network device and the adjacent access network device. Specifically, when the distance between the access network device to which the wireless frame belongs and a certain adjacent first access network device is determined to be greater than a preset threshold value, the subsequent wireless frame is determined to be processed by the access network device to which the wireless frame belongs. When the distance between the access network device and a certain adjacent first access network device is determined to be smaller than a preset threshold value, the determination of the subsequent wireless frame is determined to be processed by the corresponding target core network element 05 (such as AMF).

The frame structure decision device selection module 022 functions in the following manner: in practice, if coverage areas of two access network devices overlap and radio frames with different structures are used, in the overlapping area, one of two channels with the same frequency band may need to perform downlink data transmission at a certain moment, and the other channel may perform uplink data transmission, at this moment, the two channels interfere with each other, so that data transmission cannot be performed normally, and user experience is seriously affected. Therefore, in the present application, the frame structure decision device selection module 022 needs to determine the distance condition between the access network device to which itself belongs and the adjacent access network device.

When the distance between the access network equipment to which the self belongs and the adjacent access network equipment is determined to be larger than the preset threshold value, the wireless frames used by the access network equipment to which the self belongs and the wireless frames used by the adjacent access network equipment can be considered to be different and cannot be influenced mutually. The frame structure decision device selection module 022 determines that the selection of the radio frame can be determined by the access network device to which the radio frame belongs.

When the distance between the access network device to which the access network device belongs and the adjacent access network device is determined to be smaller than the preset threshold value, the wireless frames used by the access network device to which the access network device belongs and the wireless frames used by the adjacent access network device can be considered to be possibly mutually influenced even if the wireless frames used by the access network device to which the access network device belongs are different. Therefore, the frame structure decision device selection module 022 determines that the selection of the radio frame can be performed by the target core network element by considering the related data of a plurality of access network devices in the situation, so that communication interference between two adjacent access network devices is avoided, and user experience is improved.

It should be noted that, the case where the distance between the access network device to which the frame structure decision device selection module 022 belongs and the adjacent access network device is equal to the preset threshold may be attributed to the case where the distance between the access network device to which the frame structure decision device selection module 022 belongs and the adjacent access network device is greater than the preset threshold, or may be attributed to the case where the distance between the access network device to which the frame structure decision device selection module 022 belongs and the adjacent access network device is less than the preset threshold. That is, when the distance between the access network device to which the frame structure decision device selection module 022 belongs and the adjacent access network device is equal to the preset threshold, the determination of the radio frame may be determined by the access network device to which the frame structure decision device selection module 022 belongs, or may be determined by the target core network element 05. The present application is not particularly limited in this respect, depending on the actual requirements.

The preset threshold may be 1km, for example. In the present application, the preset threshold may be a maximum distance that the channels of the same frequency band of two adjacent access network devices will generate uplink and downlink interference. For example, the preset threshold may be twice the coverage radius of the access network device. That is, if the coverage areas of two adjacent access devices are completely misaligned, there is necessarily no uplink and downlink interference. Of course, the preset threshold may also be other possible values, specifically according to the actual situation, and is not specifically limited herein.

The frame structure judging and sending module 023 is configured to, when the frame structure judging device selecting module 022 determines that the radio frame is processed by the access network device to which the radio frame belongs, select a suitable radio frame according to the communication data demand of the communication service of the at least one user terminal 01 in the next unit time acquired by the sensing trigger signaling receiving module 021 and the sensing data demand of the sensing service. The frame structure decision and transmission module 023 is further configured to transmit the selected radio frame to the user terminal 01. Specifically, the frame structure deciding and sending module 023 may send a sensing configuration instruction to the ue 01. The instruction may include indication information for indicating the radio frame, such as a type, a name, etc. of the radio frame.

The radio frame in the present application may be used to transmit data of the sensing service and data of the communication service, so the radio frame in the present application may be obtained by appropriately modifying the existing frame structure. As shown in fig. 3 (a), a radio frame with a 2.5ms double period is shown. Referring to fig. 3 (a), the radio frame includes 10 subframes, which are D, D, D, S, U, D, D, S, U, U in order from left to right. Wherein D is a downlink subframe, and is used for transmitting downlink data; u is an uplink subframe for transmitting uplink data; s is a special subframe used for transmitting uplink and/or downlink data according to the requirement. As shown in fig. 3 (a), each subframe may be divided into 14 subframes.

Taking the radio frame shown in (a) of fig. 3 as an example, in one implementation, the modified radio frame in the present application may be shown in (b) of fig. 3 based on the radio frame.

Referring to fig. 3 (b), the first six subframes from left to right in the radio frame are communication subframes, i.e., subframes for transmitting data of communication traffic. The latter three subframes are sensing subframes for transmitting data of sensing service. In the S subframes in the middle of the two subframes, the first twelve subframes from left to right may be used for transmitting data of communication service, and the last two subframes may be subframes for distinguishing the two subframes, specifically may be subframes for identifying a start position of a perceived subframe (may be referred to as a perceived subframe start position identifier). In this way, when the access network device or the user terminal uses the radio frame to communicate, the communication subframe and the sensing subframe can be distinguished by the micro-frame for identifying the starting position of the sensing subframe. Of course, in practice, the micro frame identifying the start position of the perceived sub-frame may also be placed in other sub-frames, and the present application is not limited specifically, specifically according to the practical situation.

In the present application, the radio frame that distinguishes between the communication subframe and the sensing subframe shown in fig. 3 (b) may be referred to as a sense fused radio frame.

Based on this classification of communication subframes and perceptual subframes, based on the radio frames shown in fig. 3 (a), there may be several kinds of sense-fused radio frames as shown in table 2.

TABLE 2

Type	Frame structure/format
		1	D_TD_TD_TS_TU_TD_TS_SD_SU_SU_S
2	D_TD_TD_TS_SU_SD_SS_SD_SU_SU_S
		……	……

Wherein D _T represents a downlink communication subframe, i.e. a subframe for transmitting downlink data of a communication service, D _S represents a downlink sensing subframe, i.e. a subframe for transmitting downlink data of a sensing service, U _T represents an uplink communication subframe, i.e. a subframe for transmitting uplink data of a communication service, U _S represents an uplink sensing subframe, i.e. a subframe for transmitting uplink data of a sensing service, S _T represents a special communication subframe, i.e. a special subframe for data of a communication service, and S _S represents a special sensing subframe, i.e. a special subframe for data of a sensing service. In addition, the subframes of the last two subframes used for indicating and identifying the starting position of the sensing subframe can be any one of two adjacent subframes critical to the sensing subframe and the communication subframe, and the subframes can be determined according to actual practice.

Of course, the above definition of modification to the radio frame is merely an example, and in practice, the subframes in the radio frame may be classified in other manners. The present application is not particularly limited thereto.

Taking several radio frames shown in table 2 as an example, the sensing configuration signaling specifically sent by the frame structure deciding and sending module 023 to the user terminal may be as follows:

SIGNALING TYPE (signalling type): sense configuration (perception configuration)

UE ID (user terminal identity): 1234

FrType (radio frame type): type1 (Type 1)

Wherein Type1 is the radio frame shown in the second row of table 2.

And the general sense profile information transmission module 026 is configured to send, when the frame structure decision device selection module 022 determines that the radio frame is processed by the target core network element 05, the communication data demand of the communication service of the at least one user terminal 01 in the next unit time acquired by the sensing trigger signaling receiving module 021 and the sensing data demand of the sensing service to the target core network element (for example, AMF).

And the generic frame structure receiving module 027 is configured to receive a frame structure configuration instruction sent from the target core network element 05. Taking the target core network element 05 as an AMF as an example, the frame structure configuration instruction may be as follows:

SIGNALING TYPE (signalling type): sense configuration AMF (frame structure configuration of AMF)

PCI (PHYSICAL CELL IDENTIFIER, physical cell identity): 11

FrType (radio frame type): type1 (Type 1)

The sense frame structure sending module 028 is configured to send the indication information (such as type) of the radio frame received by the sense frame structure receiving module 027 to each of the at least one user terminal that sends data to the sense trigger signaling receiving module 021. By way of example, the signaling it sends to the user terminal may be as follows:

UE ID (user terminal identity): 1234

FrType (radio frame type): type1 (Type 1)

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

The sensing data and communication data extracting and transmitting module 025 is configured to parse the uplink data received by the terminal uploading data receiving module 024 according to the frame structure of the radio frame in the signaling received by the sensing frame structure receiving module 027 or the frame structure of the radio frame determined by the frame structure judging and transmitting 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. The upstream perceived data is then sent to the perceived server 03 that processes the perceived traffic data and the upstream communication data is sent to the network element or device in the core network 04 that processes the traffic data.

In addition, the sensing data and communication data extracting and transmitting module 025 is further configured to encode and encapsulate the downlink communication data of the communication service issued by the core network 04 and the downlink sensing data of the sensing service issued by the sensing server 03 according to the frame structure of the radio frame in the signaling received by the sensing frame structure receiving module 027 or the frame structure of the radio frame determined by the frame structure determining and transmitting module 023, and then send the encoded and encapsulated downlink communication data and the downlink sensing data to the corresponding user terminal 01.

For example, referring to fig. 2, in order to implement the technical solution provided by the embodiment of the present application, the user terminal 01 may include four modules: a communication and perceived data demand reporting module 011, a perceived configuration signaling receiving module 012, a data encapsulation transmitting module 013, and a data receiving module 014.

The communication and perceived data demand reporting module 011 is configured to perform analysis and determination on the required data amount of each communication service and the required data amount of each perceived service in the next unit time of the ue 01. At the same time, a perceived trigger signaling carrying these information is generated and sent to the access network device 02. The format of the perceptual trigger signaling may refer to the relevant expressions in the foregoing embodiments, and will not be described herein.

The sensing configuration signaling receiving module 012 is configured to receive the sensing configuration signaling from the access network device 02, and obtain therefrom indication information of a radio frame that can be used in the next unit time, and determine the radio frame that can be used in the next unit time. The perceptual configuration signaling receiving module 012 is further configured to send a first acknowledgement instruction to the access network device 02 after successfully receiving the perceptual configuration signaling. The first acknowledgement instruction is used for indicating that the ue 01 successfully receives the sensing configuration signaling.

The data encapsulation and transmission module 013 is configured to, when receiving the acknowledgement information sent by the access network device, encode and encapsulate the uplink communication data of the communication service and the uplink sensing data of the sensing service in the next unit time according to the radio frame acquired by the sensing configuration signaling receiving module 012, and send the encoded and encapsulated uplink communication data and the uplink sensing data to the access network device 02.

The data receiving module 014 is configured to receive downlink data from the access network device 02, and parse the downlink data according to the radio frame acquired by the sensing configuration signaling receiving module 012, so as to acquire downlink communication data belonging to the communication service and downlink sensing data belonging to the sensing service.

In addition, if the ue 01 itself has a sensing function and can perform a sensing service, the ue may further have a sensing module 015 for performing a sensing task of the sensing service.

For example, referring to fig. 2, in order to implement the technical solution provided by the embodiment of the present application, the target core network element 05 may include two modules: a general outline information collection module 051 and a frame structure selection and sending module 052.

Wherein, the general sense profile information collection module 051 is configured to receive general sense profile information from at least one access network device 02. The general sense profile information includes the communication data demand of the communication service of 01 in the next unit time of at least one user terminal in the coverage area of the access network equipment to which the general sense profile information belongs, and the sensing data demand and the downlink sensing demand of the sensing service. At least one access network device 02 here is an access network device having a distance to an adjacent access network device smaller than a preset threshold.

Illustratively, the data obtained by the sensory profile information gathering module 051 may be as shown in table 3 below.

TABLE 3 Table 3

The frame structure selecting and sending module 052 is configured to determine, according to all the data acquired by the generic contour information collecting module 011, a radio frame that can be used by the at least one access network device 02 in a next unit time. And sends an instruction carrying indication information indicating the radio frame to each of the at least one access network device 02. The specific form of the instruction may refer to the instruction example received by the general frame structure receiving module 027 in the foregoing embodiment, and will not be described herein.

It should be noted that, in the embodiment of the present application, the radio frames are defined in advance, and after the user terminal, the access network device and the target core network element leave the factory or register for network access or any feasible time, the specific format of each radio frame and the corresponding category, name, identifier and the like may be locally stored, so that when a certain radio frame is determined (for example, the indication information of the radio frame is known), the specific format of the radio frame may be smoothly known. Of course, it is also possible for the ue to request a specific format of a radio frame from the core network or the access network device after determining the radio frame. The implementation of how a particular user terminal obtains the particular format of the radio frame may be any feasible manner, as the application is not particularly limited.

Based on the content shown in fig. 1-3, an embodiment of the present application provides a method for determining a radio frame, which is applied to the system shown in fig. 1. Taking an access network device as a New Radio (NR), a user terminal is a user terminal with a sensing module, and a target core network element is an AMF, as shown in fig. 4, the method includes 401-410 (including S1-S7):

401. The user terminal has a sensing requirement, and starts sensing to perform sensing service corresponding to the sensing requirement.

For example, the sensing requirement may be generated after the user terminal receives the user operation, for example, the smart wearable device receives the operation of detecting the heart rate indicated by the user, and performs the sensing service of detecting the heart rate. The sensing requirement can also be that the core network sequentially sends the sensing requirement to the user terminal through the sensing server and the access network equipment. Of course, any other feasible situation is also possible.

In the embodiment of the application, the sensing requirement can include an ID of the sensing service or a required data volume of the sensing service. By way of example, perceived needs may be as shown in table 4 below.

TABLE 4 Table 4

In one implementation, the 401 step may be implemented by the sensing module 015 in the previous embodiment.

402. NR obtains total sense business demand data.

The total general sense business demand data comprises: the sum of communication data demands of communication services of at least one user terminal in a coverage area of the access network device in a next unit time and the sum of perceived data demands of perceived services of at least one user terminal in the next unit time.

Wherein the communication data demand includes an uplink communication data demand and a downlink communication data demand; the perceived data demand includes an upstream perceived data demand and a downstream perceived data demand.

The sum of the communication data demands includes a sum of the upstream communication data demands and a sum of the downstream communication data demands; the sum of perceived data requirements includes a sum of upstream perceived data requirements and a sum of downstream perceived data requirements.

In the present application, at least one user terminal may refer to all user terminals that need to perform a awareness service and/or a communication service within the coverage area of the NR.

In one implementation, referring to fig. 5 in conjunction with fig. 4, the step 402 may specifically include 4021-4023:

4021. the user terminal obtains the general sense service demand data in the next unit time and sends the general sense service demand data to the NR.

Wherein, the sense of business demand data includes: communication data demand of communication traffic and perceived data demand of perceived traffic. Wherein the communication data demand includes an uplink communication data demand and a downlink communication data demand; the perceived data demand includes an upstream perceived data demand and a downstream perceived data demand.

Of course, taking one ue to send the traffic demand data as an example, it may be that at least one ue actually sends the traffic demand data, and the implementation is similar to 4021.

The user terminal may specifically send a sensing trigger instruction to the NR, where the sensing service requirement data may be carried in the instruction. The specific form of the sensing trigger signaling and the generic service requirement data may refer to the relevant descriptions in the foregoing embodiments, and will not be repeated herein.

In one implementation, step 4021 may be implemented by the sense trigger module 015 in the previous embodiments.

4022. The NR receives the next unit time of the traffic demand data from the at least one user terminal.

In one implementation, step 4022 may be implemented by the sense trigger signaling receiving module 021 in the foregoing embodiment.

4023. And the NR calculates total general sense business demand data according to all the general sense business demand data.

For example, each of the total sensory traffic demand data may be calculated according to the following formulas (1) - (4):

Wherein T _Tuplink is the sum of the uplink communication data demands of the communication service of the next unit time of at least one user terminal, For the uplink communication data demand of the user terminal i in the next unit time in the user terminals with the communication demand (i.e. the communication service needs to be performed in the next unit time) in the at least one user terminal, T _Tdownlink is the sum of the downlink communication data demands of the communication service in the next unit time of the at least one user terminal, and/ >For the downlink communication data demand of user terminal i in the next unit time in the user terminals with communication demands (i.e. needs to perform communication services in the next unit time) in at least one user terminal, T _Suplink is the sum of the uplink sensing data demands of sensing services in the next unit time of at least one user terminal,/>For the uplink perceived data demand of the user terminal i in the next unit time in the user terminals with perceived demand (i.e. perceived service is needed in the next unit time) in the at least one user terminal, T _Sdownlink is the sum of the downlink perceived data demands of the perceived service in the next unit time of the at least one user terminal,For the downlink sensing data demand of the user terminal i in the next unit time in the user terminals with sensing demands (i.e. the sensing service needs to be performed in the next unit time) in the at least one user terminal, N is the total number of user terminals with communication demands in the at least one user terminal, and M is the total number of user terminals with sensing demands in the at least one user terminal.

Based on the technical schemes corresponding to 4021-4023, NR can be enabled to successfully acquire the total sense service demand data, and data support is provided for the determination of the subsequent wireless frames.

403. NR judges whether the distance from the adjacent base station is greater than a preset threshold.

If NR determines if the distance to the neighboring base station is greater than the preset threshold, then execution 404, if NR determines that the distance to the neighboring base station is less than or equal to the preset threshold, then execution S1.

Here, although the case where the distance from the adjacent base station to the NR determination is equal to the preset threshold is ascribed to the case where the distance from the adjacent base station to the NR determination is smaller than the preset threshold, in practice, the case where the distance from the adjacent base station to the NR determination is equal to the preset threshold may be ascribed to the case where the distance from the adjacent base station to the NR determination is larger than the preset threshold. At this time, if the NR determines whether the distance from the neighboring base station is greater than or equal to the preset threshold, it is performed 404, and if the NR determines whether the distance from the neighboring base station is less than the preset threshold, it is performed S1.

Of course, the above-mentioned judging step may not actually exist, and the NR may be performed 404 in a case where it is determined that the distance from the neighboring base station is greater than (or greater than or equal to) the preset threshold value, and may be performed S1 in a case where it is determined that the distance from the neighboring base station is less than (or less than or equal to) the preset threshold value.

In one implementation manner, the step 403 may be implemented by the frame structure decision device selection module 022 in the foregoing embodiment.

404. The NR calculates a first communication subframe requirement value and a first perceived subframe requirement value from the total perceived traffic demand data.

The first communication subframe requirement value comprises a first uplink communication subframe requirement value and a first downlink communication subframe requirement value, and the first perception subframe requirement value comprises a first uplink perception subframe requirement value and a first downlink perception subframe requirement value.

Illustratively, the first uplink communication subframe requirement value, the first downlink communication subframe requirement value, the first uplink sensing subframe requirement value, and the first downlink sensing subframe requirement value may be calculated according to the following formulas (5) - (8):

Where N _Tuplink is a first uplink communication subframe requirement, N _Tdownlink is a first downlink communication subframe requirement, N _Suplink is a first uplink sensing subframe requirement, N _Sdownlink is a first downlink sensing subframe requirement, T _Tuplink is a sum of uplink communication data requirements of communication services of a next unit time of at least one user terminal, T _Tdownlink is a sum of downlink communication data requirements of communication services of a next unit time of at least one user terminal, T _Suplink is a sum of uplink sensing data requirements of sensing services of a next unit time of at least one user terminal, T _Sdownlink is a sum of downlink sensing data requirements of sensing services of a next unit time of at least one user terminal, and N _Frame(s) is a number of subframes of each radio frame in all optional radio frames.

405. The NR determines a first radio frame based on the first communication subframe requirement value and the first perceptual subframe requirement value.

In one implementation, referring to fig. 5 in conjunction with fig. 4, steps 405 may include 4051 and 4052:

4051. and determining the radio frames including the first uplink communication subframe demand value in the preset range of the number of uplink communication subframes in all the selectable radio frames, including the first uplink sensing subframe demand value in the preset range of the number of uplink communication subframes, including the first downlink communication subframe demand value in the preset range of the number of downlink communication subframes, and including the first downlink sensing subframe demand value in the preset range of the number of downlink sensing subframes as candidate radio frames.

Wherein the number of subframes of all the optional radio frames is the same, i.e., N _Frame(s) as described above.

For example, the preset range of a may be (0.8 a,1.2 a), and a may be the number of uplink communication subframes, or the number of uplink sensing subframes, or the number of downlink communication subframes, or the number of downlink sensing subframes. Based on this, the above-described determination process may be as follows.

If a certain radio frame satisfies:

then the radio frame is a candidate radio frame.

Wherein,For the number of uplink communication subframes of the radio frame,/>For the number of downlink communication subframes of the radio frame,/>For the number of uplink aware subframes of the radio frame,/>The number of subframes is perceived for the downlink of the radio frame.

4052. A first radio frame is determined based on all candidate radio frames.

In one implementation, referring to fig. 6 in conjunction with fig. 5, 4052 may specifically include 4052A or 4052B:

4052A, determining any one of all candidate radio frames as the first radio frame.

Based on the technical scheme corresponding to 4052A, because one radio frame can be rapidly selected as the first radio frame, the selection mode is simple, and therefore the efficiency of the radio frame determination scheme provided by the application is higher.

4052B, determining the candidate radio frame with the largest sum of the first similarity value, the second similarity value, the third similarity value and the fourth similarity value among all the candidate radio frames as the first radio frame.

The first similarity value is used for representing the proximity degree of the number of uplink communication subframes and the first uplink communication subframe requirement value, the second similarity value is used for representing the proximity degree of the number of uplink sensing subframes and the first uplink sensing subframe requirement value, the third similarity value is used for representing the proximity degree of the number of downlink communication subframes and the first downlink communication subframe requirement value, and the fourth similarity value is used for representing the proximity degree of the number of downlink sensing subframes and the first downlink sensing subframe requirement value. For example, if the number of uplink communication subframes in the a-candidate radio frame is 5, the number of uplink communication subframes in the a-candidate radio frame is 7, and the first uplink communication subframe requirement value is 4, the first similarity of the a-candidate radio frame is greater. The rest of the similarity values are the same.

Based on the technical scheme corresponding to 4052B, because the radio frame with the actual subframe value closer to the calculated four subframe requirement values (the first uplink communication subframe requirement value, the first downlink communication subframe requirement value, the first uplink sensing subframe requirement value and the first downlink sensing subframe requirement value) can be selected as the first radio frame, the selection mode is more reasonable, so that the reliability of the radio frame determination scheme provided by the application is higher.

Based on the technical schemes corresponding to 4051 and 4052, a radio frame suitable for the service requirement of the user terminal in the NR coverage area can be successfully determined from the optional radio frames, so that smooth communication of the communication sense fusion data between the subsequent NR and the user terminal is ensured.

Of course, in practice, a candidate radio frame having the largest sum of at least one of the first, second, third, and fourth similarity values may be determined as the first radio frame. In this scheme, the candidate radio frame closest to at least one subframe (at least one of an uplink communication subframe, a downlink communication subframe, an uplink sensing subframe and a downlink sensing subframe) and the corresponding subframe requirement value (the uplink communication subframe corresponds to the first communication uplink subframe requirement value, the downlink communication subframe corresponds to the first communication downlink subframe requirement value) are selected from the candidate radio frames as the first radio frame, so that the effect is more reasonable compared with the technical scheme corresponding to 4051A.

In one implementation manner, the step 405 (including the step 4051 and the step 4052 (including the step 4052A or the step 4052B)) may be implemented by the frame structure deciding and transmitting module 023 in the foregoing embodiment.

406. The NR transmits first indication information for indicating the first radio frame to the user terminal.

Illustratively, the NR may send a sensing configuration signaling to the user terminal, where the sensing configuration signaling may carry the first finger information. The specific form of the signaling may refer to the relevant expression in the foregoing embodiments, and will not be described herein.

Step 407 is performed after step 406.

S1, NR sends total sense business demand data to AMF.

In one implementation manner, the step S1 may be implemented by the passsense profile information transmission module 026 in the foregoing embodiment.

S2, AMF receives the total sense business requirement data from NR.

Of course, only the AMF receives the total traffic demand data of one NR as an example. In practice, the AMF receives the aggregate traffic demand data from at least one NR (or access network device).

In one implementation manner, the step S2 may be implemented by the general sense profile information collection module 051 in the foregoing embodiment.

S3, the AMF calculates a second communication subframe requirement value and a second perception subframe requirement value according to all the total communication service requirement data.

The second communication subframe demand value comprises a second uplink communication subframe demand value and a second downlink communication subframe demand value, and the second perception subframe demand value comprises a second uplink perception subframe demand value and a second downlink perception subframe demand value.

The specific implementation of step S3 may refer to the relevant description of step 404, which is not described herein. The difference is that in the step S3, when the second communication subframe requirement value and the second sensing subframe requirement value are calculated, the total sensing service requirement data acquired by at least one NR is used, so that when the calculation is performed, the sum of the communication data requirements (including the sum of the uplink communication data requirements and the sum of the downlink communication data requirements) and the sum of the sensing data requirements (including the sum of the uplink sensing data requirements and the sum of the downlink sensing data requirements) of all user terminals corresponding to the total sensing service requirement data of at least one NR are needed.

S4, the AMF determines a second wireless frame according to the second communication subframe requirement value and the second perception subframe requirement value.

The specific implementation and the relevant beneficial effects of step S4 may refer to the relevant description of step 405 in the foregoing embodiment, which is not repeated here.

S5, the AMF sends second indication information for indicating the second radio frame to the NR.

Illustratively, the AMF may achieve the objective of step S8 by sending a frame structure configuration instruction carrying the second instruction information to the NR. For specific instructions, reference may be made to the description of the general frame structure receiving module 027 in the foregoing embodiment, which is not repeated herein.

In one implementation, the steps S3-S5 may be implemented by the frame structure selection and transmission module 052 in the foregoing embodiment.

S6, NR receives second indication information from the AMF.

In one implementation, the step S6 may be implemented by the passsense frame structure receiving module 027 in the foregoing embodiment.

S7, the NR sends third indication information for indicating the second radio frame to the user terminal.

The NR may, for example, achieve the purpose of step S7 by sending an instruction carrying the third indication information to the user terminal. The specific instruction may refer to the related expression of the sense frame structure sending module 028 in the foregoing embodiment, which is not described herein again.

In one implementation, the step S7 may be implemented by the generic frame structure sending module 028 in the foregoing embodiment.

Based on the technical schemes corresponding to the S1-S7, the working of determining the wireless frame is transmitted to the AMF for processing under the condition that the distance between NR and the adjacent access network equipment is smaller than a preset threshold value, namely communication interference can occur between NR and the adjacent access network equipment. And further, on the premise of determining the radio frame, the problem of communication interference between connected access network devices is avoided, and the use experience of users is ensured.

Step S7 is followed by step 407.

407. The user terminal receives the fourth indication information from the NR and sends a third acknowledgement order to the NR.

The fourth indication information is used for indicating a third wireless frame, and the third confirmation instruction is used for indicating that the terminal successfully receives the fourth indication information.

When step 406 is executed before step 407, the fourth indication information is the first indication information, the third radio frame is the first radio frame, and the third acknowledgement command may be the first acknowledgement command; when step S6 is performed before step 407, the fourth indication information is a third indication information, the third radio frame is a second radio frame, and the third acknowledgement command may be a second acknowledgement command.

In one implementation, step 407 may be implemented by the perceptual configuration signaling receiving module 012 in the previous embodiment.

408. And the user terminal uses the third radio frame to perform data communication of the sensing service and the communication service with the access network equipment in the next unit time.

In one implementation, referring to fig. 7 in conjunction with fig. 4, the step 408 may specifically include 4081 and 4082:

4081. And the user terminal packages the uplink sensing data of all sensing services and the uplink communication data of all communication services into uplink data according to the third radio frame in the next unit time, and sends the uplink data to the NR.

In one implementation, step 4081 may be implemented by the data encapsulation transmit module 013 in the foregoing embodiment.

4082. The user terminal receives the downlink data from the NR, analyzes the downlink sensing data belonging to the sensing service and the downlink communication data belonging to the communication service in the downlink data according to the third radio frame, and carries out corresponding processing on the downlink sensing data and the downlink communication data.

In one implementation, step 4082 may be implemented by the data receive module 014 in the previous embodiment.

In the embodiment of the present application, there is no absolute sequence between the 4081 step and the 4082 step, the 4081 step may be performed before the 4082 step, the 4082 step may be performed before the 4081 step, and the 4081 step and the 4082 step may be performed synchronously.

409. The NR receives a third acknowledgement instruction from the user terminal.

410. The NR uses the third radio frame to communicate data of the sensing service and the communication service with the user terminal in the next unit time.

In one implementation, referring to fig. 7 in conjunction with fig. 4, the step 410 may specifically include 4101-4105:

4101. And the NR receives the uplink data from the user terminal, and analyzes the uplink data belonging to the sensing service and the uplink communication data belonging to the communication service in the uplink data according to the third radio frame.

4102. And the NR sends the uplink sensing data in the uplink data obtained by analysis to the sensing server.

4103. And the NR sends the uplink communication data in the uplink data obtained by analysis to the core network.

4104. The NR receives the downlink sensing data corresponding to the user terminal from the sensing server and the downlink communication data corresponding to the user terminal from the core network.

4105. And the NR encodes and packages the downlink sensing data and the downlink communication data according to the third radio frame to obtain downlink data, and sends the downlink data to the user terminal.

In one implementation, steps 4101-4105 may be implemented by the sense data and communication data extraction and transmission module 025 of the previous embodiments.

It should be noted that steps 4101-4103 need to be performed after step 4081, and step 4082 needs to be performed after steps 4104 and 4105. The steps 4101-4103 and the steps 4104-4105 are not necessarily sequential, and the present application is not limited in particular.

Based on the technical scheme provided by the application, under the condition that an access network device needs to determine a radio frame for communication of communication fusion data (uplink and downlink data of communication service and uplink and downlink data of sensing service) with a user terminal in the coverage area of the access network device in the next unit time. In the present application, for the access device, first, the total traffic demand data is acquired. The total traffic data may include the sum of the uplink data demand and the sum of the downlink data demand of the traffic of at least one ue in the coverage area of the total traffic data and the sum of the uplink data demand and the downlink data demand of the traffic of the sensing service. Because if coverage areas of two access network devices (for example, base stations) overlap and radio frames with different structures are used, in the overlapping area, there may be a need to perform downlink data transmission on one of two channels with the same frequency band at a certain moment, and the other need to perform uplink data transmission, at this moment, the two channels interfere with each other, so that the data transmission cannot be performed normally, and user experience is seriously affected.

Based on this, in the present application, the access network device determines the radio frame itself if the distance between the access network device and the adjacent access network device is greater than a preset threshold. Specifically, the access network device determines the subframe requirements of the communication service and the sensing service of the user terminal in the coverage area of the access network device in the next unit time according to the total sensing service requirement data. I.e. a first uplink communication sub-frame requirement value, a first downlink communication sub-frame requirement value, a first uplink aware sub-frame requirement value and a first downlink aware sub-frame requirement value are calculated. Then, according to the calculated first uplink communication subframe requirement value, the first downlink communication subframe requirement value, the first uplink sensing subframe requirement value and the first downlink sensing subframe requirement value, a proper first radio frame can be determined.

In the present application, the access network device may send the distance between the access network device and the adjacent access network device to the target core network element (specifically, may be an AMF) to determine the radio frame when the distance between the access network device and the adjacent access network device is less than a preset threshold. Specifically, the access network device may send all the data from the user terminal acquired by itself to the target core network element. And the target core network element determines the subframe requirements of the communication service and the perception service of the user terminal in the coverage area of the access network equipment in the next unit time according to all the data sent by all the access network equipment received by the target core network element, and further determines a proper second radio frame according to the subframe requirements. The target core network element may then send second indication information indicating the second radio frame to the access network device.

Based on the above two cases, the access network device may finally send the indication information (i.e. the first indication information or the third indication information) indicating the first radio frame or the second radio frame to the user terminal, so that the user terminal uses the first radio frame or the second radio frame to perform data communication of the sensing service and the communication service with the access network device in the next unit time

In the technical scheme provided by the application, the access network equipment can combine the requirement that at least one user terminal in the coverage area needs to communicate uplink and downlink data in the next unit time, determine the uplink and downlink subframe number needed by the communication service and the uplink and downlink subframe number needed by the sensing service, and further determine the wireless frame suitable for the access network equipment and the user terminal to communicate in the next unit time. Therefore, the technical scheme solves the problem of how to determine the frame of a proper radio frame on the basis of the network architecture of the existing time division duplex system so as to reasonably allocate uplink and downlink channel resources, and enables the user terminal and the access network equipment to smoothly communicate the sense fusion data.

In addition, based on the technical scheme provided by the application, under the condition that the target core network element determines the radio frames, all related access network devices adopt the same radio frames. Therefore, even if the distance between two adjacent access network devices is smaller and the overlapping coverage area exists, one of the channels with the same frequency band in the overlapping coverage area does not need to carry out downlink data transmission, and the other channel carries out uplink data transmission, so that the problem of mutual interference between the two channels and hard data transmission is solved, and the use experience of a user is ensured.
