[0089] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0090] In a wireless communication system, semi-persistent scheduling (SPS) is a resource allocation method that balances flexibility and resource efficiency. It lies between dynamic scheduling and static scheduling. Semi-persistent scheduling can allocate resources that are periodically repeated in the time domain and have fixed transmission block numbers and positions in the frequency domain, and is applicable to services with fixed packet sizes and periodic transmissions.

[0091] In a Long Term Evolution (LTE) system, parameters related to semi-persistent scheduling are configured through Radio Resource Control (RRC) signaling. The resource allocation process of semi-persistent scheduling is executed by the Medium Access Control (MAC) layer of the base station and is activated / deactivated in combination with dynamic instructions of the Physical Downlink Control Channel (PDCCH). After the resources of semi-persistent scheduling are activated, the terminal and the base station can send and receive data directly on the resources of semi-persistent scheduling without a scheduling indication until the resources of semi-persistent scheduling are deactivated or reallocated.

[0092] In the 5G (5th Generation Mobile Communication Technology) system, in addition to supporting the allocation of semi-static scheduling resources for terminals by combining the PDCCH dynamic command activation / deactivation method in the above LTE system, the semi-static scheduling authorization for the PUSCH (Physical Uplink Shared Channel) can also be implemented by RRC configuration. The resources of semi-static scheduling allocated to the terminal in this way take effect immediately and do not need to be activated / deactivated by the PDCCH dynamic command.

[0093] The above-mentioned resource allocation method for semi-static scheduling only considers the resource adjustment of a single terminal, and the allocated resources are those of other terminals. When the network load is high and the available resources are insufficient, this resource allocation strategy will increase the probability of resource allocation failure.

[0094] In an industrial network, there are requirements for collaborative operation among multiple industrial devices, and the continuity of service transmission for all industrial devices needs to be ensured. When these industrial devices communicate through a wireless network, the management station in the industrial wireless network may need to allocate resources to multiple terminal stations simultaneously. However, the resource allocation methods for semi-static scheduling in the above LTE and 5G systems will not be able to meet the requirements of service continuity and transmission reliability for each terminal station. This is because when using the above resource allocation method, only the resource adjustment of a single terminal station is considered. When applying this resource allocation method to an industrial wireless network, it may cause the time of switching transmission resources for each terminal station to be out of sync. For example, some terminal stations have already switched to the target transmission resources after reallocation, while some terminal stations are still using the original transmission resources, and there is an overlap between the reallocated target transmission resources and the original transmission resources, resulting in a resource conflict phenomenon and causing service transmission failure.

[0095] In view of this, how to ensure the service continuity and transmission reliability of each terminal station has become an urgent problem to be solved.

[0096] The resource reallocation method provided by the embodiments of this application can be applied to Figure 1 the implementation environment shown. Among them, the controller and the management station are connected by a wired network or a wireless network, and the controller and the management station can communicate. Industrial devices (such as Figure 1 Industrial Device 1 to Industrial Device n shown, where n is a positive integer greater than 1) and the corresponding terminal stations (such as Figure 1 Terminal Station 1 to Terminal Station n shown) are connected by a wired network or a wireless network, and the industrial devices and the terminal stations can communicate. The management station and the terminal stations communicate wirelessly through the air interface. The aforementioned management station can also be called the master station, and the industrial devices and the terminal stations can also be called the slave stations.

[0097] Next, in combination with the accompanying drawings in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0098] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0099] In an exemplary embodiment, as Figure 2 shown, a resource reallocation method is provided, and this method is described by taking the management station shown in Figure 1 as an example. The resource reallocation method includes the following steps 201 to step 202:

[0100] Step 201, determine multiple target terminal stations that need to perform resource reallocation from multiple terminal stations of the management station.

[0101] In an industrial wireless network, the management station needs to allocate transmission resources to each terminal station. For each terminal station, the transmission resources allocated by the management station are deterministic dedicated transmission resources, that is, before the management station reallocates resources to this terminal station next time, this transmission resource is periodically and fixedly used by this terminal station to ensure the high reliability requirements and low transmission delay requirements of the real-time services of the terminal station.

[0102] After the management station allocates the above-mentioned transmission resources to each terminal station, the channel quality of the wireless channel between the terminal station and the management station may change. For example, it changes with the change of the position of the terminal station, so that the transmission resources allocated by the management station to the terminal station may not match the actual channel state and service transmission requirements of the terminal station (for example, the terminal station has new services or some services no longer need to be processed, etc.). This is not conducive to improving the reliability of service transmission, and even affects the service continuity and reliability of all coordinated terminal stations.

[0103] In view of this, in the embodiments of the present application, the management station needs to perform resource reallocation. The management station can determine multiple target terminal stations that need to perform resource reallocation from multiple terminal stations of the management station. These multiple terminal stations refer to all terminal stations within the jurisdiction of the management station (or the network coverage range of the management station), and the target terminal station can refer to the terminal station determined by the management station from these multiple terminal stations that needs to perform resource reallocation.

[0104] In a possible implementation, for a terminal station, the management station can detect the size of the transmission resources required for transmitting the services of the terminal station (such as real-time services). When the required transmission resources are greater than the resource threshold (i.e., the required transmission resources are large), the terminal station can be determined as the target terminal station.

[0105] In another possible implementation, for a terminal station, the management station can obtain the channel quality of the wireless channel between the management station and the terminal station, and the size of the data volume of the data packet to be transmitted by the terminal station. If the channel quality deteriorates and the data volume of the data packet to be transmitted is large, it indicates that more transmission resources are required, and the terminal station can be determined as the target terminal station.

[0106] In another possible implementation, if the management station simultaneously detects that the channel quality of multiple terminal stations deteriorates, the multiple terminal stations with deteriorated channel quality can be respectively determined as the target terminal stations.

[0107] In other possible implementations, for each terminal station, the management station can obtain the amplitude of the channel quality change of the terminal station within a preset time period (the preset time period can refer to a preset time period, which can be set as needed during implementation). For example, the management station can obtain the channel measurement result of the terminal station, and determine the amplitude of the deteriorated channel quality or the amplitude of the improved channel quality according to the channel measurement result. If the amplitude of the channel quality change is greater than the preset amplitude threshold, it indicates that the amplitude of the deteriorated channel quality is large or the amplitude of the improved channel quality is large, and it is necessary to timely adjust the transmission resources allocated to the terminal station to meet the service transmission reliability requirements of the terminal station and improve the spectrum efficiency, and the terminal station can be determined as the target terminal station.

[0108] In this embodiment, the above preset amplitude threshold can refer to the preset amplitude value of the channel quality change. The above preset amplitude threshold can be obtained through pre-testing, or calculated by using a machine learning model, or fitted by using a simulation model, and can be specifically determined according to the actual situation, and this embodiment of the present specification does not make any limitations thereto. Taking the signal-to-noise ratio as an example to represent the channel quality, the amplitude of the channel quality change can be the difference in the signal-to-noise ratio between the current moment and the previous moment of the channel, and the preset amplitude threshold is a preset signal-to-noise ratio threshold value, which can be set as needed during implementation, and this embodiment of the present specification does not make any limitations thereto.

[0109] Based on this, the management station can determine multiple target terminal stations that need resource reallocation from multiple terminal stations of the management station. Of course, it can be understood that the multiple target terminal stations can be some or all of the multiple terminal stations of the management station. The method of selecting target terminal stations is not limited to the above embodiments and can also be determined according to the actual situation. For example, terminal stations that do not need to use resources currently, terminal stations with a reduced amount of required resources, terminal stations with improved channel quality, etc. can also be selected as target terminal stations for global resource adjustment. The embodiments of this specification do not limit this.

[0110] Since the total amount of transmission resources in the industrial wireless network is fixed, then, when a terminal station requires more transmission resources, if the management station directly reallocates target transmission resources to this terminal station using the remaining available resources (transmission resources not allocated to each terminal station) in the industrial wireless network, there may be a situation of scheduling failure due to insufficient remaining available resources. Therefore, in the embodiments of this application, after the management station determines multiple target terminal stations, it uniformly adjusts the transmission resources of these multiple target terminal stations. For example, for a target terminal station with a relatively large decrease in channel quality, its transmission resources can be increased, and for a target terminal station with a relatively large increase in channel quality, its transmission resources can be decreased.

[0111] Exemplarily, the management station can recycle the currently allocated transmission resources of each target terminal station. Then, the management station reallocates target transmission resources to each target terminal station using the remaining available resources in the industrial wireless network (including the recycled transmission resources) to meet the resource requirements of each target terminal station and improve the success rate of resource scheduling.

[0112] Step 202: Send resource reallocation information to each target terminal station.

[0113] After the management station reallocates target transmission resources to each target terminal station, it can generate resource reallocation information for each target terminal station and send the resource reallocation information to each target terminal station.

[0114] Among them, the resource reallocation information can include resource indication information and resource effectiveness information. Each resource indication information is used to indicate the target transmission resources reallocated by the management station for each target terminal station, and each resource effectiveness information is used to indicate that each target terminal station synchronously switches to the corresponding reallocated target transmission resources. Among them, the so-called "synchronization" can mean that the time for each target terminal station to switch to the corresponding reallocated target transmission resources is relatively consistent. For example, the frame boundaries for each target terminal station to switch to the reallocated target transmission resources are aligned.

[0115] After each target terminal station receives the resource reallocation information sent by the management station, it parses the resource reallocation information to identify the content indicated by the resource reallocation information. After successful parsing, the target terminal station can send a response message to the management station. The target terminal station can also determine the target transmission resources reallocated by the management station for the target terminal station according to the resource indication information included in the resource reallocation information, and switch to the target transmission resources reallocated by the management station for the target terminal station according to the indication of the resource activation information, so as to ensure that each target terminal station synchronously switches to the corresponding reallocated target transmission resources, and the activation times of the reallocated target transmission resources corresponding to each target terminal station are relatively consistent.

[0116] In the above embodiments, through each resource activation information, it can be ensured that the target transmission resources reallocated by the management station for each target terminal station are activated synchronously. Each resource activation information can also ensure the resource synchronous switching between the management station and each target terminal station, and each target terminal station synchronously switches to the reallocated target transmission resources, thereby avoiding the problem of resource conflict caused by the asynchronous switching time of each target terminal station's target transmission resources (for example, if the switching times of each target terminal station's target transmission resources are asynchronous, there may be a situation where some target terminal stations have switched to the reallocated target transmission resources, while some target terminal stations stay on the original transmission resources, but there is a resource overlap between the reallocated target transmission resources and the original transmission resources). Therefore, the problem of service transmission failure caused by resource conflict can be avoided, and the embodiments of the present application can ensure the service continuity and transmission reliability of each target terminal station.

[0117] Hereinafter, the content included in the resource indication information will be introduced exemplarily.

[0118] In the embodiments of the present application, the resource indication information may at least include any one of the following: frequency domain resource indication information; frequency domain resource indication information and modulation and coding scheme (MCS); time domain resource indication information and frequency domain resource indication information; time domain resource indication information, frequency domain resource indication information and modulation and coding scheme.

[0119] Among them, the time domain resource indication information may include the time domain position and time domain period of the time domain resources in the reallocated target transmission resources, and the frequency domain resource indication information includes the number of resource blocks and the resource block position of the frequency domain resources in the reallocated target transmission resources.

[0120] For the modulation and coding scheme, as described above, the channel quality of the wireless channel between the terminal station and the management station may change over time. If the channel quality deteriorates but the modulation and coding scheme used for scheduling remains unchanged, it may lead to data reception failure. If the channel quality improves but the modulation and coding scheme used for scheduling remains unchanged, it will result in resource waste.

[0121] In the embodiments of the present application, during the resource reallocation process, the modulation and coding scheme can be dynamically adjusted to match the channel quality of the wireless channel between the management station and the target terminal station, improving the reliability of service transmission and avoiding resource waste.

[0122] Hereinafter, an exemplary introduction to the content included in the resource effectiveness information will be given.

[0123] In the embodiments of the present application, the resource effectiveness information may include: the effectiveness mode indication information of the reallocated target transmission resource, or the effectiveness time indication information of the reallocated target transmission resource, or the effectiveness mode indication information of the reallocated target transmission resource and the effectiveness time indication information of the reallocated target transmission resource, etc. Of course, other possible information may also be included in the resource effectiveness information, such as the resource effectiveness identifier, etc., which can be determined according to the actual situation specifically, and the embodiments of this specification do not limit this.

[0124] First, the effectiveness mode indication information will be introduced.

[0125] The effectiveness mode indication information is used to indicate the effectiveness mode of the target transmission resource reallocated by the management station for the target terminal station. Optionally, the above effectiveness mode can be, for example, immediate effectiveness. For example, after the target terminal station sends a response message to the management station, the target terminal station can use the target transmission resource reallocated by the management station in the next wireless frame of the wireless frame used to send the response message.

[0126] Optionally, the above effectiveness mode indication information can be used to indicate that after the target terminal station receives the broadcast message sent by the management station, it switches to the reallocated target transmission resource in the Nth frame after the first wireless frame for transmitting the broadcast message, where N is a positive integer. For example, N is equal to 1. Of course, the above effectiveness mode indication information is not limited to the above examples. Those skilled in the art may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should all be covered within the protection scope of the embodiments of this specification.

[0127] In one embodiment, please refer to Figure 3 , in this embodiment, after step 202, the following steps 301 and 302 may further be included Figure 3 shown in

[0128] Step 301: Receive response messages sent by each target terminal station.

[0129] The response message is sent by the target terminal station after successfully parsing the resource reallocation information. When the management station receives the response messages sent by each target terminal station, it determines that each target terminal station has received the resource reallocation information and has successfully parsed the resource reallocation information.

[0130] Step 302: Send a broadcast message to each target terminal station.

[0131] The management station can send a broadcast message to each target terminal station by means of broadcasting or multicasting.

[0132] In the embodiment of the present application, to ensure that data is transmitted on the target transmission resources reallocated by the management station for the target terminal stations synchronously among the target terminal stations and between the target terminal stations and the management station, the management station sends a broadcast message after successfully receiving the response messages sent by all target terminal stations.

[0133] After the target terminal station receives the broadcast message sent by the management station, the target terminal station switches to the reallocated target transmission resource in the Nth frame after the first radio frame for transmitting the broadcast message. As described above, N can be a positive integer, so as to realize that each target terminal station synchronously switches to the corresponding reallocated target transmission resource.

[0134] In one embodiment, please refer to Figure 4 , on the basis of the embodiment shown in Figure 3 , in this embodiment, step 302 may include Figure 4 step 401 shown in

[0135] Step 401: Repeatedly send a broadcast message to each target terminal station.

[0136] In the embodiment of the present application, to improve the reliability of the broadcast message transmission, the broadcast message can be repeatedly transmitted multiple times. Each broadcast message may include a resource activation identifier, the total number of transmissions of the broadcast message, and the current transmission number of the broadcast message. The total number of transmissions and the current transmission number are used for the target terminal station to determine the first radio frame for transmitting the last broadcast message, and the resource activation identifier is used for the target terminal station to activate the reallocated target transmission resource in the Nth frame after the first radio frame.

[0137] In the embodiment of the present application, the target transmission resources reallocated by the target terminal station may be uplink transmission resources and / or downlink transmission resources. Correspondingly, the resource activation identifier is used to activate the uplink transmission resources and / or downlink transmission resources reallocated by the management station for the target terminal station.

[0138] After the target terminal station receives the broadcast message repeatedly sent by the management station, it can determine the first radio frame for transmitting the last broadcast message based on the total number of transmissions and the current transmission number. Optionally, the transmission interval of the broadcast message can be pre-agreed and stored in a preset storage location of the target terminal station. In this way, when the target terminal station receives a broadcast message, it can calculate the radio frame (i.e., the first radio frame) for transmitting the last broadcast message according to the total number of transmissions, the current transmission number included in the broadcast message, and the transmission interval stored in the preset storage location.

[0139] In one embodiment, the broadcast message may further include the transmission interval of the broadcast message, which is used for the target terminal station to determine the first radio frame according to the total number of transmissions, the current transmission number, and the transmission interval. After the target terminal station receives a broadcast message, it can calculate the radio frame for transmitting the last broadcast message according to the total number of transmissions, the current transmission number, and the transmission interval included in the broadcast message.

[0140] Among them, the transmission interval can be represented by a numerical value. For example, a transmission interval of 1 can indicate that the broadcast message is transmitted on consecutive radio frames, and a transmission interval of 2 can indicate that the broadcast message is transmitted with an interval of one radio frame, and so on. Of course, it can be understood that the setting method of the transmission interval is not limited to the above examples. Those skilled in the art may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should all be covered within the protection scope of the embodiments of this specification.

[0141] After each target terminal station calculates the first radio frame for transmitting the last broadcast message, it then activates the reallocated target transmission resources in the Nth frame after the first radio frame according to the resource activation identifier.

[0142] After activating the reallocated target transmission resources in the Nth frame after the first radio frame, the management station and each target terminal station can then transmit service data based on the corresponding activated target transmission resources.

[0143] In the above embodiments, the indication information of the effective mode enables the understanding of the switching of the reallocated target transmission resources to be consistent among the target terminal stations and between the management station and each target terminal station, avoiding the problem of resource conflicts caused by out-of-sync resource adjustments and thus resulting in service transmission failures.

[0144] The above embodiments introduce the indication information of the effective mode. Next, the indication information of the effective time will be introduced.

[0145] The effective time indication information can be used to indicate the effective time of the target transmission resources reallocated by the management station for the target terminal station. The effective time indication information may include the identifier of a wireless frame, such as a frame number. The effective time refers to the time when the target terminal station switches to the target transmission resources reallocated by the management station for it. If the effective time corresponding to each target terminal station is the same, each target terminal station can synchronously switch to the target transmission resources reallocated by the management station for it when the effective time arrives.

[0146] When multiple target terminal stations adjust the transmission resources simultaneously, it is necessary to ensure that multiple target terminal stations synchronously switch to the target transmission resources reallocated by the management station for them to transmit data. Therefore, it is necessary to reasonably configure the effective time indication information to avoid the problem of resource conflict caused by some target terminal stations having successfully switched to the target transmission resources reallocated by the management station for them, while some target terminal stations have not successfully received the resource reallocation information and still stay on the original transmission resources. Hereinafter, in the case where the resource effective information includes the effective time indication information of the target transmission resources, an exemplary description of the method for the management station to determine the resource effective information is given.

[0147] See Figure 5 , the management station can execute Figure 5 Steps 501 to 503 shown in the figure to generate the resource effective information:

[0148] Step 501, obtain the target time difference.

[0149] In the embodiments of the present application, the target time difference is used to represent the number of wireless frames corresponding to the total time required for the management station to transmit the resource reallocation information of each target terminal station and for each target terminal station to successfully respond.

[0150] Among them, the successful response of the target terminal station may refer to the target terminal station receiving the resource reallocation information, parsing the resource reallocation information, and sending a response message to the management station after successful parsing. The management station receiving this response message indicates that the target terminal station has successfully responded. Therefore, the target time difference can represent the time difference between the time when the management station sends the first resource reallocation information and the time when the management station receives the response messages of all target terminal stations, and this target time difference is represented by the number of wireless frames.

[0151] In the embodiments of the present application, the management station may transmit the resource reallocation information of each target terminal station either repeatedly or once. If the resource reallocation information is transmitted repeatedly, then the target time difference may represent the time from when the resource reallocation message of the first target terminal station is sent until the configuration of all target terminal stations is completed, and may at least include the number of radio frames corresponding to the total time required for the management station to repeatedly transmit the resource reallocation information of each target terminal station and for each target terminal station to successfully respond. Here, the manner in which the management station transmits the resource reallocation information of each target terminal station is not limited. Among them, the completion of the configuration of all target terminal stations may mean that the management station receives the response messages sent by all target terminal stations that need to have their resources reallocated (as described above, the target terminal station parses the resource reallocation information and sends a response message to the management station after successful parsing).

[0152] It can be understood that the above target time difference may also include the time required for other possible information processing during the transmission process, such as the time for retransmission after failure, the time for waiting for a response, etc. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0153] For example, taking the case where the number of multiple target terminal stations is 2 and the resource reallocation information is not transmitted repeatedly, for two target terminal stations, two resource reallocation information need to be sent. It takes 4 radio frames to send one resource reallocation information to a target terminal station, and it takes 4 radio frames for the target terminal station to parse the resource reallocation information and return a response message to the management station. Then, it takes 8 radio frames from when one resource reallocation information is sent until the management station receives the response information from each target terminal station, and the time interval between sending these two resource reallocation information is 2 radio frames. Then, the above target time difference is 10 radio frames (2 radio frames plus 8 radio frames). Of course, the calculation method of the target time difference is not limited to the above example. Those skilled in the art may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should all be covered within the protection scope of the embodiments of this specification.

[0154] Step 502: Add the second radio frame for transmitting the first resource reallocation information to the target time difference to obtain the effective time.

[0155] Among them, the first resource reallocation information is the earliest sent resource reallocation information among the resource reallocation information of each target terminal station.

[0156] The management station may add this target time difference to the time frame (the second radio frame) for sending the first resource reallocation information as the effective time for the target transmission resources reallocated by the management station for each target terminal station.

[0157] Step 503: Generate resource activation information according to the activation time.

[0158] As described above, the resource activation information includes the activation time indication information of the target transmission resource. If the management station uses this activation time as the activation time indication information, the resource activation information can be obtained.

[0159] The management station carries the activation time indication information as the resource activation information in the resource reallocation information and sends it to each target terminal station, so that each target terminal station and the management station can synchronously switch to the corresponding reallocated target transmission resource in the wireless frame indicated by the above activation time indication information for subsequent data transmission.

[0160] In one embodiment, after determining multiple target terminals, during the process of generating the resource reallocation information, the management station can estimate the above target time difference and the time frame for sending the first resource reallocation information, and then add the second wireless frame to the target time difference to obtain the activation time, thereby generating the resource activation information included in each resource reallocation information. After the management station generates each resource reallocation information, it sends the resource reallocation information to each target terminal station respectively.

[0161] When multiple target terminal stations simultaneously reallocate transmission resources, on the one hand, it is necessary to ensure that the transmission resources before and after adjustment of the same target terminal station are synchronized with the management station to avoid data transmission and reception failures caused by inconsistent transmission resources used by the target terminal station and the management station; on the other hand, it is also necessary to ensure that each target terminal station synchronously switches from the original transmission resource to the target transmission resource reallocated by the management station for it. In the embodiments of the present application, when simultaneously adjusting the transmission resources of multiple target terminal stations, through diverse resource allocation strategies, the synchronization of resource adjustment between target terminal stations and between the target terminal station and the management station is ensured, resource conflicts are avoided, and the service continuity of the target terminal station before and after resource adjustment is ensured.

[0162] In an exemplary embodiment, a resource reallocation method is provided. Taking the terminal station shown in Figure 1 as an example for illustration. The resource reallocation method includes the following steps:

[0184] In one embodiment, when the resource activation information includes activation time indication information, the method further includes:

[0186] Regarding the implementation manner and beneficial effects of the resource reallocation method for a terminal station, reference may be made to the relevant descriptions in the foregoing embodiments of the resource reallocation method for a management station, which will not be elaborated herein.

[0187] Hereinafter, through two examples, the interaction between a management station (MS) and a target terminal station (TS) in the resource reallocation method according to the embodiments of the present application will be exemplarily introduced.

[0188] 1) Example 1, see Figure 6 , and the resource reallocation method includes Figure 6 the following steps shown in

[0189] Step 601, resource reallocation decision.

[0190] In this step, for each of multiple terminal stations of the management station, the management station obtains the change amplitude of the channel quality of the terminal station within a preset time period. If the change amplitude of the channel quality is greater than a preset amplitude threshold, it is determined that the terminal station is a target terminal station that needs to perform resource reallocation, and finally multiple target terminal stations ( Figure 6 TS1 to TSn shown in

[0191] Step 602, resource reallocation execution.

[0195] The effectiveness mode of the target transmission resource indicated by the effectiveness mode indication information is broadcast message activation.

[0196] Step 603: The resource reallocation result is issued.

[0197] In this step, the management station sends corresponding resource reallocation information to each target terminal station.

[0205] 2) Example 2, see Figure 7 , the resource reallocation method includes Figure 7 The following steps are shown:

[0206] Step 701: resource reallocation decision.

[0207] In this step, for each of the multiple terminal stations of the management station, the management station obtains the channel quality change amplitude of the terminal station within a preset time period. If the channel quality change amplitude is greater than the preset amplitude threshold, the terminal station is determined to be a target terminal station for resource reallocation, and finally multiple target terminal stations ( Figure 7 TS1 to TSn shown).

[0208] Step 702: resource reallocation is performed.

[0209] In this step, the management station reallocates target transmission resources to each target terminal station and generates resource reallocation information corresponding to each target terminal station.

[0210] Among them, the resource reallocation information includes the following: the time domain position and time domain period of the time domain resources;

[0213] In this step, the management station sends the corresponding resource reallocation information to each target terminal station.

[0214] Step 704, configuration success response.

[0215] In this step, each target terminal station parses the received resource reallocation information, and in the case of successful parsing, sends a response message to the management station.

[0216] Step 705, service data transmission.

[0217] In this step, the management station and the target terminal station switch to the target transmission resources on the radio frame indicated by the effective time indication information for service data transmission.
