Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the internet of vehicles system, the internet of vehicles terminal realizes the interaction of the vehicle and the intelligent information of X (vehicle, person, traffic road side infrastructure and network) through vehicle-to-everything (V2X) technology. The interaction modes of V2X communication include: communication between vehicles (vehicle to vehicle, V2V), between vehicles and roadside infrastructure (vehicle to infrastructure, V2I), between vehicles and pedestrians (vehicle to pedestrian, V2P), between vehicles and network (vehicle to network, V2N). Illustratively, the roadside infrastructure may be a Road Side Unit (RSU).

Fig. 1 is a schematic diagram of an architecture of V2X communication. As shown in fig. 1, V2X communication includes V2V communication, V2P communication, V2I communication, and V2N communication, and V2X traffic is transmitted through a sidelink (sidelink) or Uu port during V2X communication.

In practical application, V2X realizes typical application scenes such as information service, traffic safety, traffic efficiency and the like by virtue of omnibearing connection and efficient information interaction with people, vehicles, roads and cloud platforms. The internet of vehicles terminal can obtain various information services through V2I and V2N communication, including traffic signal lamp information, nearby area vehicle information, vehicle navigation, emergency rescue, information entertainment services and the like. The information such as the speed, the position, the driving condition and the pedestrian activity of surrounding vehicles can be obtained in real time through V2V and V2P communication, and the collision early warning function is realized through an intelligent algorithm, so that traffic accidents are avoided. The functions of guiding the vehicle speed and the like can be realized through V2I communication, and the traffic efficiency is improved.

With the continued development of technology, new wireless (NR) communication systems are currently being introduced, in which V2X is referred to as NR-V2X. In the NR-V2X system, automatic driving needs to be supported, and thus, higher requirements are put on data interaction between vehicle terminals, such as higher throughput, lower latency, higher reliability, larger coverage, more flexible resource allocation, and the like.

In the NR-V2X system, communication through the side-link is referred to as a V2X sidelink communication mode. In this communication mode, the terminal device may operate in a scene with network coverage or in a scene without network coverage.

In a scenario with network coverage, the V2X sidelink communication mode is further divided into a centralized scheduling transmission mode and a distributed transmission mode.

In the centralized scheduling transmission mode, the transmission resources of the terminal device for transmitting the V2X service on the side uplink are allocated by the network device, and are called as mode1 in the NR-V2X system, and are also called as mode1; in the distributed transmission mode, the network device configures a V2X sidelink resource pool, and when the terminal device transmits V2X service each time, transmission resources are acquired from the network-configured resource pool, and no network device scheduling is needed, and the mode is called mode2 in an NR-V2X system, and is also called mode2. See the description of the schematic diagrams shown in fig. 2 and 3 for details.

Fig. 2 is a schematic diagram of a system architecture to which mode 1 is applied. Fig. 3 is a schematic diagram of a system architecture to which mode 2 is applied. Referring to fig. 2 and 3, the first terminal device and the second terminal device are V2X communication-capable terminal devices for performing V2X communication, and V2X communication is performed between the first terminal device and the second terminal device through a wireless communication interface, and communication is performed between the first terminal device and the network device, or between the second terminal device and the network device through a wireless communication interface. For clarity, the wireless communication interface between the first terminal device and the second terminal device is referred to as a first air interface, for example a PC5 interface, and the wireless communication interface between the first terminal device and the network device or between the second terminal device and the network device is referred to as a second air interface, for example a Uu interface.

Referring to fig. 2, as an example, transmission resources of a first terminal device and a second terminal device are allocated by a network device, and the first terminal device and the second terminal device transmit data on a side uplink according to the resources allocated by the network device; the network device may allocate resources of single transmission to the first terminal device and the second terminal device, or allocate resources of semi-static transmission to the first terminal device and the second terminal device, which will not be described herein.

As another example, the first terminal device may select one resource in the resource pool to transmit data to the second terminal device, as shown in fig. 3. Specifically, the first terminal device may select a transmission resource from the resource pool in a listening manner, or select a transmission resource from the resource pool in a random selection manner, and transmit data to the second terminal device at the selected transmission resource, where the manner in which the first terminal device selects the transmission resource may be determined according to an actual situation, which is not described herein.

In the scenario without network coverage, the terminal device uses the mode 2 to transmit, and at this time, the resource pool is acquired in a preconfigured manner. The specific transmission manner is the same as the mode 2 described above, and will not be described here again.

From the above analysis, unlike the conventional air interface (Uu interface) uplink and downlink communication, the V2X communication technology may use the PC5 interface for side communication, and the network device may pre-allocate a resource pool to the PC5 interface communication, which may be referred to as a V2X resource pool in the embodiment of the present application. Optionally, the resource pool includes a series of frequency domain resources and time domain resources.

Correspondingly, the two ways of data transmission by using the resources in the resource pool by the terminal equipment are also introduced, namely a interception way and a random selection way. The interception mode is a listen-before-select mode, and before sending service data, the sending terminal device firstly listens for a period of time, determines a proper sending resource from the resource pool, and then sends the service data. And randomly selecting a mode, namely randomly selecting a transmission resource for transmitting the service data from the resource pool when the terminal equipment transmits the service data.

At present, the resources contained in the resource pool are configured by the network equipment, and the terminal equipment can select the resources from the resource pool configured by the network to transmit and receive data according to the preset rule (namely the interception mode or the random selection mode), so that the problems of high energy consumption, poor interception effect or unreasonable resource utilization of the terminal equipment can exist. The specific analysis is as follows:

On the one hand, the validity of the preset rule is controlled by parameters of the network device, such as: the network may configure the period and the number of times that the terminal needs to monitor before selecting the resource, but if the configuration of the period and the number of times of monitoring is unreasonable, there may be a problem that the terminal energy consumption is large or the sensing effect is poor, for example, when the monitoring period configured by the network device is too short or the number of times of monitoring is too large, there may be a problem that the energy consumption of the terminal device at the transmitting end is large, which is not beneficial to the terminal energy saving, and when the monitoring period configured by the network device is too long or the number of times of monitoring is too small, there may be a problem that the sensing effect of the terminal device at the transmitting end is poor, that is, the sensing effect of the terminal resource occupation is not necessarily effective.

On the other hand, the validity of the resource pool configured by the network device is checked, for example, resources with larger interference and poor data transceiving effect may exist in the resource pool, that is, if the resource pool configured by the network device is not suitable, the problem of unreasonable resource utilization rate exists.

Aiming at the problems, the technical conception process of the application is as follows: the inventor of the application finds that the terminal equipment has large energy consumption, poor monitoring effect or unreasonable resource utilization in the use process of the resource pool is caused by lack of feedback optimization means of the terminal equipment, so that an optimization control method of a resource selection mechanism can be provided to optimize control parameters related to the resource pool configuration and/or resource occupation sensing process, specifically, if the terminal equipment timely reports recording data related to the use of the resource pool after using the resources in the resource pool, so that the network equipment adjusts the resource selection configuration parameters and/or the resource pool configuration information based on the reported recording data, and further the problems in the use process of the resource pool are solved.

Based on the above technical conception process, the embodiment of the application provides a control method for selecting resources, when terminal equipment uses sub-resources in a resource pool configured by network equipment to perform data transmission, related information of using the resource pool can be recorded, further related record data of using the resource pool can be obtained later, the related record data of using the resource pool is reported to the network equipment through a first message, and correspondingly, after the network equipment receives the first message, the network equipment can adjust the configuration information of the resource pool and/or adjust the configuration parameters for selecting resources configured by the terminal equipment according to the related record data of using the resource pool at least included in the first message, thereby improving the utilization rate of the terminal equipment when using the resources in the resource pool, and solving the problems of high energy consumption of the terminal equipment, poor monitoring effect or unreasonable resource utilization of the resource pool in the existing resource selection process.

It can be appreciated that the control method for selecting resources provided in the embodiment of the present application may be used in a vehicle networking system, may also be used in any D2D system or side transmission system, and may also be applied to a third generation mobile communication (the 3rd generation mobile communication,3G), a long term evolution (long term evolution, LTE) system, a fourth generation mobile communication (the 4th generation mobile communication,4G) system, a long term evolution advanced system (advanced long term evolution, LTE-a), a cellular system related to a third generation partnership project (the 3rd generation partnership project,3GPP), a fifth generation mobile communication (the 5th generation mobile communication,5G) system, and a communication system that evolves subsequently. The embodiment of the application is not limited thereto.

The network device involved in the embodiment of the present application may be a common base station (such as NodeB or eNB or gNB), a new radio controller (new radio controller, NR controller), a centralized network element (centralized unit), a new radio base station, a remote radio module, a micro base station, a relay (relay), a distributed network element (distributed unit), a receiving point (transmission reception point, TRP), a transmission point (transmission point, TP), or any other device, but the embodiment of the present application is not limited thereto.

The terminal device according to the embodiment of the present application is a terminal device with a sidestream communication capability, and is also a device for providing voice and/or data connectivity to a user, for example, a handheld device with a wireless connection function, an on-board device, a roadside unit, and the like. Common terminal devices include: a mobile phone, tablet, notebook, palm top, mobile Internet Device (MID), wearable device, such as a smart watch, smart bracelet, pedometer, etc. It will be appreciated that embodiments of the present application are not limited to specific implementations of terminal devices.

The technical scheme of the application is described in detail through specific embodiments. It should be noted that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 4 is a flowchart of a first embodiment of a control method for resource selection according to the present application. The method is explained with information interaction between the terminal device and the network device. As shown in fig. 4, the control method for resource selection may include the steps of:

s400, the terminal equipment sends a first message to the network equipment, wherein the first message at least comprises: the resource pool uses the associated record data.

Optionally, in the embodiment of the present application, before the terminal device sends the first message to the network device, recording data related to use of the resource pool may be acquired, which is not limited in this embodiment.

In the V2X scenario, when the terminal devices use the PC5 port to perform side-link communication, the transmitting terminal device may first select a transmission resource from a resource pool preconfigured by the network device, and then transmit information to the receiving terminal device on the transmission resource.

Optionally, in each process of selecting and/or using transmission resources from the resource pool, the terminal device may record and/or collect and store the relevant situation of each time of using the resource pool, so as to obtain the record data related to the use of the resource pool.

Optionally, the terminal device may acquire the record data related to the use of the resource pool periodically or in real time, and feed the record data back to the network device, so that the network device may timely acquire the related information of the use of the resource pool by the terminal device.

It may be understood that in the embodiment of the present application, the record data related to the use of the resource pool may be all record data of the use of the resource pool by the terminal device in a preset period of time, or may be record data of a single use resource pool, which is not limited herein.

Optionally, after the terminal device obtains or determines the record data related to the resource pool usage, the record data related to the resource pool usage may be sent to the network device in the form of a first message.

It can be appreciated that the first message is not limited to include the record data related to the use of the resource pool, and may further include other information, for example, capability information, indication information, etc. of the terminal device, which are not described herein.

Illustratively, in an embodiment of the present application, the above-described record data (i.e., the resource pool usage-related data record) includes at least one of the following:

A first item: a resource pool sensing period used by the terminal equipment;

the second item: sensing the repetition times by a resource pool used by the terminal equipment;

It can be understood that the resources in the resource pool preconfigured by the network device are public resources, in order to avoid using resource conflict, the terminal device needs to sense or monitor the condition that each sub-resource in the resource pool is occupied before initiating the service of the terminal device, and the sensing process of the terminal device is controlled by the parameters configured by the network device.

Optionally, the parameters configured by the network device at least include a resource pool sensing period P, that is, a period of time when the terminal device senses or listens to whether each sub-resource in the resource pool is occupied each time before using the sub-resource in the resource pool.

Optionally, the parameters configured by the network device may further include a resource pool sensing repetition number K, where the sensing repetition number K indicates a number of times that the terminal device senses or listens whether each sub-resource in the resource pool is occupied before using the sub-resource in the resource pool.

Optionally, when the parameter configured by the network device does not include the repetition number K of the resource pool sensing, that is, when K is not configured, the default K is equal to 1, and the resource pool sensing process of each round is 1; while in configuring K, the resource pool sensing process needs to be repeated K times per round. It can be appreciated that if k=0 is configured, the terminal device may directly send data on the resource selected from the resource pool, without performing resource awareness. Thus, in this embodiment, K is a natural number.

It is understood that the resource pool resource may also be expressed as a sub-resource in the resource pool or a resource in the resource pool, and the embodiments of the present application and their limitations are defined in the above description.

Fig. 5 is a schematic diagram illustrating a resource occupancy sensing procedure performed by a terminal device. Alternatively, the case where K is equal to 2 and time N is the data transmission time is described as an example. As shown in fig. 5, in two time windows before the data sending time N (i.e., a resource sensing window including time (N-2P) and a resource sensing window including time (N-P)), the terminal device needs to sense that each sub-resource included in the resource pool is occupied, so that according to the resource pool sensing results in the two time windows, the terminal device can send data by preferentially considering using the sub-resource which is not occupied or the sub-resource which has smaller interference when sending the data at the time N, thereby ensuring the reliability of data transmission as much as possible.

Wherein K represents the number of times the terminal device needs to execute the resource sensing process before the data sending time N, and each resource sensing process corresponds to a resource sensing time window, as shown in fig. 5, the resource sensing time window includes time (N-k×p), where the value range of K is {0,1,2, … …, K }, and P is the resource pool sensing period.

Third item: the frequency of the inconsistent resource pool sensing result of the terminal equipment and the actual resource occupation condition is the proportion of the total frequency of the resource pool sensing of the terminal equipment;

Optionally, the fact that the resource pool sensing result of the terminal device does not accord with the actual resource occupation situation may be interpreted as: after the resource sensing process, the terminal equipment selects a certain sub-resource which is not occupied or has smaller interference, but finds that the sub-resource is occupied or the interference on the sub-resource is relatively larger when actually sending data, and then the data transmission effect is poor.

Optionally, the reason that the resource pool sensing result of the terminal device is inconsistent with the actual resource occupation situation may be that the resource pool sensing period P and the resource pool sensing repetition number K are not reasonably configured, after all, a time interval exists between the resource pool sensing process of the terminal device and the actual data sending moment, and in the time interval, the resource usage situation in the resource pool may change, so that the situation that the resource pool sensing result is inconsistent with the actual resource occupation situation may occur.

Alternatively, in general, the perceived repetition number K of the resource pool determines the perceived accuracy of the terminal device for resource occupation to a certain extent. Specifically, the larger the perceived repetition number K of the resource pool, the higher the perceived accuracy, and the smaller the perceived repetition number K of the resource pool, the lower the perceived accuracy.

In the embodiment of the application, the first parameter and the second parameter can be optimized through the third parameter, so that the error rate of the terminal equipment is reduced as much as possible, and the resource sensing frequency is reduced or the sensing period is prolonged.

Fourth item: the total information of the pre-configured resource pool;

optionally, if the network device is preconfigured with the resource pool total information, the terminal device may record the resource pool total information preconfigured by the network device in the resource sensing process.

The fifth item: configuration information corresponding to resources in the resource pool with average occupied rate higher than a first threshold value;

Optionally, in an embodiment of the present application, the configuration information corresponding to the resources of the resource pool with the average occupied rate higher than the first threshold may also be interpreted as configuration information corresponding to the first sub-resource in the resource pool, where the average occupied rate of the first sub-resource is higher than the first threshold.

For example, assuming that the terminal device performs 10 rounds of resource sensing procedures (fig. 5 shows a round of resource sensing procedures), the terminal device senses that the number of times a certain sub-resource 1 (a first sub-resource) in the resource pool is occupied is 7 times, the average occupied rate of the sub-resource 1 is 0.7 (i.e. 7 divided by 10), and assuming that the first threshold value is 0.5, the terminal device needs to record configuration information corresponding to the sub-resource 1.

Sixth item: configuration information corresponding to resources in the resource pool with average occupied rate lower than a second threshold value;

Alternatively, in an embodiment of the present application, the configuration information corresponding to the resources of the resource pool with the average occupied rate lower than the second threshold may be interpreted as configuration information corresponding to a second sub-resource in the resource pool, where the average occupied rate of the second sub-resource is lower than the second threshold.

For example, assuming that the terminal device performs 10 rounds of resource sensing procedures (fig. 5 shows a round of resource sensing procedures), the terminal device senses that a certain sub-resource 2 (i.e., a second sub-resource) in the resource pool is occupied for 2 times, the average occupied rate of the sub-resource 2 is 0.2 (i.e., 2 divided by 10), and assuming that the second threshold is 0.4, the terminal device needs to record configuration information corresponding to the sub-resource 2.

Seventh item: the proportion of the resources of the resource pool with the average occupied rate higher than a third threshold value to the total resources of the resource pool;

Optionally, in the resource pool, the number of sub-resources satisfying the first condition is a proportion of the total number of sub-resources in the resource pool, where the first condition is that an average occupied rate of the sub-resources is higher than a third threshold.

For example, assuming that the terminal device performs the resource sensing process for a period of time, it is determined that the resource pool includes 8 sub-resources, where an average occupancy rate of the 5 sub-resources is higher than a third threshold, and a ratio of the sub-resources of the resource pool with the average occupancy rate higher than the third threshold to the resources of the whole resource pool is 5/8, that is: 0.625.

Eighth item: the proportion of the resources of the resource pool with average occupied rate lower than the fourth threshold value to the total resources of the resource pool;

Optionally, in the resource pool, the number of sub-resources satisfying the second condition is a proportion of the total number of sub-resources in the resource pool, where the second condition is that the average occupied rate of the sub-resources is lower than a fourth threshold.

For example, assuming that the terminal device performs the resource sensing process for a period of time, it is determined that the resource pool includes 8 sub-resources, where the average occupancy rate of 3 sub-resources is lower than the fourth threshold, and then the proportion of the sub-resources of the resource pool with the average occupancy rate lower than the fourth threshold to the resources of the whole resource pool is 3/8, that is: 0.375.

It can be understood that the embodiment of the present application is not limited to the specific values of the first threshold, the second threshold, the third threshold and the fourth threshold and the respective size relationships, which may be determined according to the actual scenario, and will not be described herein.

Ninth item: average occupancy rate of resources in the resource pool;

alternatively, this ninth term can also be interpreted as: and (3) averaging the ratio of the total number of occupied sub-resources in the resource pool to the total number of sub-resources in the resource pool in a period of time.

Optionally, in practical application, the fourth item (the preconfigured total information of the resource pool) may be optimized through the fifth item to the ninth item, where the fifth item and the sixth item may be used to accurately identify which sub-resources need to be reserved and which need to be replaced, so as to ensure that resources in the resource pool have a better data transmission effect; the seventh, eighth and ninth items may be used to determine an overall utilization rate of the resource pool, so that the network device may dynamically adjust the size of the resource pool, and avoid a phenomenon that the utilization rate of the resource pool is too high or too low.

Tenth item: whether the terminal equipment supports a resource pool resource random selection function;

In practical application, some terminal devices do not need to sense the occupation condition of resources in advance before selecting resources from a resource pool for data transmission due to service types or capability grades, but directly select transmission resources in the resource pool at random for data transmission. That is, the terminal device supporting the resource pool resource random selection function does not need to sense the resource occupation condition in advance, and the terminal device not supporting the resource pool resource random selection function needs to sense the resource occupation condition in advance. Therefore, when the terminal equipment uses the resources in the resource pool, it can also record whether the terminal equipment supports the resource pool resource random selection function.

Eleventh item: priority information of the terminal equipment, wherein the priority information is used for judging whether to adopt a resource pool resource random selection function.

Optionally, in practical application, the priorities of different terminal devices are provided, so when the terminal device uses the resources of the resource pool, whether the terminal device adopts the random selection function of the resource pool or not, that is, whether a resource sensing process is needed before sending data or not can be determined based on the priorities provided by the terminal device.

For example, assuming that there are multiple terminal devices that all need to use the resources in the resource pool, it can be determined which terminal devices can employ the resource pool random selection function and which terminal devices need to perform the resource sensing process according to the priority order of the multiple terminal devices.

For example, for two terminal devices with different priorities, it is assumed that a terminal device with a higher priority may use a resource pool resource random selection function, while a terminal device with a lower priority does not use a resource pool resource random selection function, and before using the resources of the resource pool, a resource sensing process is required.

Optionally, since the resource selection logic of the resource random selection terminal and the resource perception selection terminal are completely different, the tenth item and the eleventh item are used for notifying the network device of the terminal type information, so as to avoid mixing and optimizing the data reported by the terminal device needing to perform resource perception and the terminal device not needing to perform resource perception (the resource random selection terminal).

Optionally, in an embodiment of the present application, at least one of the first threshold, the second threshold, the third threshold, the fourth threshold, and the priority information is configured in any one of the following manners:

A pre-configuration mode, a default configuration mode, a system broadcast message configuration mode or a special signaling configuration mode.

For the pre-configuration mode, specifically, the network device may pre-configure the first threshold, the second threshold, the third threshold, the fourth threshold and the priority information for the terminal device, so that when the terminal device records the relevant data used by the resource pool, the corresponding data item in the recorded data may be generated based on any one of the first threshold, the second threshold, the third threshold, the fourth threshold and the priority information.

As shown in fig. 6, before the step S400, the control method for resource selection may further include the following steps:

S601, the terminal equipment sends a second message to the network equipment, wherein the second message comprises: and the first indication information is used for indicating that the record data related to the resource pool use recorded by the terminal equipment is advisable.

S602, the network equipment sends a response message of the second message to the terminal equipment, wherein the response message comprises: and the second indication information is used for indicating the terminal equipment to report the record data related to the resource pool use.

Optionally, the network device determines that there is non-extracted record data related to resource pool usage in the terminal device based on the first indication information in the received second message, and if the network device agrees to extract the record data related to resource pool usage stored in the terminal device, sends the second indication information to the terminal device through the second message response message, so as to instruct the terminal device to report the record data related to resource pool usage stored in the terminal device.

It will be appreciated that the steps S601 and S602 in fig. 6 are optional steps, and are not limited in practical application.

Fig. 7 is a schematic flow chart of a third embodiment of a control method for resource selection according to the present application, which is exemplary, based on the foregoing embodiments. As shown in fig. 7, before the step S400, optionally, the control method for resource selection may further include the following steps:

S701, the terminal device sends capability indication information to the network device, where the capability indication information is used to indicate whether the terminal device supports collection or recording of at least one item of data in the record data related to resource pool usage.

Optionally, in practical applications, some terminal devices may not support the situation of collecting or recording the record data related to the use of the resource pool due to the service type or the capability level, so the terminal device may report capability indication information to the network device to indicate that the terminal device supports or does not support the collection or recording of the data item in the record data related to the use of the resource pool.

Correspondingly, the network device determines whether the terminal device supports collecting or recording at least one item of data in the record data related to the resource pool use by receiving the capability indication information reported by the terminal device.

In one possible design of the embodiment of the present application, the number of capability indication information reported by the terminal device is one, where the one capability indication information is used to indicate whether the terminal device has a capability of recording any data item in the record data related to the use of the resource pool. That is, all data items of the resource pool usage related record data included in the first message share one capability indication information, and only the terminal device supports the capability corresponding to the capability indication information, the terminal device can record any data item in the resource pool usage related record data.

In another possible design of the embodiment of the present application, the number of capability indication information reported by the terminal device is at least two; at this time, each capability indication information is used to indicate whether the terminal device has the capability of recording a single data item or a group of data items in the recording data related to the resource pool usage. That is, the resource pool included in the first message corresponds to the independent capability indication information respectively using one or all of the data items of the related recording data, and the terminal device can record the corresponding data item only if the capability indication information of the corresponding data item indicates permission.

As an example, in an embodiment of the present application, the method may further comprise the steps of:

S702, the network equipment sends a configuration message to the terminal equipment, wherein the configuration message comprises the following components: and data collection indicating information for indicating whether or not the terminal device is permitted to record the data item in the record data related to the use of the resource pool.

For example, the network device may send data collection indication information to the terminal device via a configuration message to indicate whether the terminal device is allowed to collect data items in the record data related to the resource pool usage.

Optionally, the value of the data collection indication information is used for indicating permission or prohibition; for example, assume that the value of the data collection instruction information is 0 or 1, and accordingly, when the value of the data collection instruction information is 1, permission is instructed, that is, collection of the corresponding data item is permitted; when the value of the data collection instruction information is 0, prohibition is instructed, that is, collection of the corresponding data item is not permitted. In another implementation, the meaning of 0 or 1 may be reversed, and the application is not limited in this regard.

As an example, when the value of the data collection indication information indicates permission, the terminal device records the data item in the resource pool usage related record data; as another example, the terminal device does not record the data item in the resource pool usage-related record data when the value of the data collection instruction information instructs prohibition.

In one possible design of the embodiment of the present application, the number of data collection instruction information is one, and the one data collection instruction information is used for indicating whether all data items in the record data are collected or not. That is, the first message includes that whether all data items in the relevant record data are collected in the resource pool is indicated by sharing one data collection indication information, that is, when the terminal device receives one data collection indication information, if the value of the data collection indication information indicates permission, the terminal device is permitted to collect all data items in the relevant record data, and if the value of the data collection indication information indicates prohibition, the terminal device is not permitted to collect any data items in the relevant record data.

In another possible design of the embodiment of the present application, the number of the data collection instruction information is at least two; at this time, each data collection instruction information is used to instruct collection or non-collection of a single data item or a group of data items in the record data. That is, the resource pool included in the first message is indicated by using independent data collection indication information about whether a group or a single data item in the related record data is collected or not, that is, each data collection indication may be used to control whether a single data item or a group of data items is collected or not. For example, it is assumed that the terminal device receives at least two data collection indication information, and is a first data collection indication and a second data collection indication, if the value of the first data indication information indicates permission, it indicates that the terminal device may collect a single data item or a group of data items controlled by the first data indication information, and if the value of the second data indication information indicates prohibition, it indicates that the terminal device is not permitted to collect a single data item or a group of data items controlled by the second data collection indication information.

In another implementation, some of the data items in the usage-related record data of the resource pool are allowed to be unassociated with any capability indication information, at which point these data items may be recorded or collected by default by the terminal device.

Optionally, after S702, the method may further include the following steps:

s703, the network device sends data record configuration information to the terminal device, where the data record configuration information includes: and the data record duration configuration information and/or the data record reporting configuration information.

Illustratively, the data record configuration information includes: and the data record duration configuration information and/or the data record reporting configuration information. The data recording duration configuration information is used for configuring the time length of the data recording.

Optionally, the data record reporting configuration information may include at least one of the following types of configurations:

a1, reporting period configuration information by a data record;

A2, reporting repeated times configuration information by the data record;

A3, reporting the cell range configuration information by the data record.

The configuration information of the reporting period of the data record is used for determining the reporting period of the data record, for example: reporting the record data related to the use of the resource pool once every 200ms by the terminal equipment; it can be understood that the embodiment of the present application is not limited to a specific reporting period value.

The configuration information of the number of repeated reporting of the data record is used for determining the number of repeated reporting of the data record, for example: the terminal equipment can report the record data related to the use of the resource pool for a plurality of times so as to ensure that the network equipment can successfully receive the record data; it can be understood that the embodiment of the present application does not limit the specific number of repeated reporting.

The data record reporting cell range configuration information is used for defining a cell range of reporting the relevant record data used by the resource pool, and if the cell where the terminal equipment resides is not the cell in the data record reporting cell range configuration information, the terminal equipment is not allowed to report the relevant record data used by the resource pool.

Optionally, the cell range configuration form is any one of the following:

At least one tracking area identity (TRACKING AREA code: TAC), at least one cell identity or at least one public land mobile network (public land mobile network: PLMN) identity.

Wherein the cell identity is represented by a cell global identity (cell global identifier: CGI); or by frequency point + physical cell identity (PHYSICAL CELL IDENTIFIER: PCI).

The configuration information in step S702 and the data record configuration information in S703 may be transmitted through the same message or transmitted separately through different messages, which is not limited in the present application. Optionally, in the embodiment of the present application, after the terminal device receives the data record configuration information from the network device, it may process the data record configuration information, for example, record the record data related to the resource pool usage based on the data record configuration information, and then execute S400, that is, report the record data related to the resource pool usage to the network device through the first message.

Optionally, after the terminal device receives the data record configuration information from the network device, the terminal device may determine the data record duration configuration information and/or the data record reporting configuration information from the data record duration configuration information and/or the data record reporting configuration information.

For example, assuming that the data recording configuration information includes both data recording duration configuration information and data recording reporting configuration information, the terminal device may determine a time length for recording data according to the data recording duration configuration information, and execute a corresponding recording process when using resources in the resource pool, and may execute a reporting process of recording data according to the data recording reporting configuration information.
