BACKGROUND

[0004] A terminal reports a buffer status report (BSR) to a base station to inform the base station that the terminal has data to send, and then the base station allocates resource block (RB) resources to the terminal based on the reported BSR.

[0005] In related technologies, when a terminal cannot normally send a BSR to a base station, the terminal preferentially selects a scheduling request (SR) to report the BSR, so as to obtain resources based on the reported BSR. Referring to FIG. 1, the process of obtaining resources through the SR includes: transmitting SR information to the base station through a physical uplink control channel (PUCCH) resource, the base station allocating resources for sending the BSR to the terminal in response to the SR information, the terminal sending the BSR to the base station based on the allocated resources, and the base station obtaining the amount of data to be uploaded by the terminal based on the BSR, and then allocating RB resources to the terminal.

[0154] In order to make the purposes, technical solutions and advantages of the present application clearer, 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 should not be used to limit the present application.

[0155] The reporting method of buffer status information and the resource allocation method provided by the embodiments of the present application can be applied in the application environment as shown in Figure 2. In the industrial wireless communication scenario, the user station 202 notifies the management station 204 that it has data to send by sending the BSR to the management station 204, and the management station 204 allocates RB resources for the terminal according to the received BSR, and then the user station 202 can transmit uplink data to the management station through the RB resources allocated by the management station 204. The user station 202 can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices, industrial devices (such as robotic arms), portable wearable devices, communication devices (such as wireless network terminals, base stations, etc.), Internet of Things devices, which can be smart speakers, smart televisions, smart air conditioners, smart car devices, etc. The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, etc. The management station 204 can be a base station or a base station controller, etc. for wireless resource allocation device.

[0156] In the industrial wireless communication scenario, the user station 202 mainly transmits process data when it is in normal operation (because the real-time requirement of process data is relatively high, in the embodiments of the present application, the process data will be referred to as real-time data in the following), and other services are relatively less. The data packet of real-time data is small, and is sent periodically, so the management station 204 can pre-configure periodic wireless resources for the user station 202 according to the size and sending period of real-time data in the user station 202, that is, the user station 202 can send real-time data to the management station 204 on the pre-configured periodic wireless resources. For example, referring to Figure 3, the management station 204 can allocate wireless resources with a period of 1ms for the user station 202. In the embodiments of the present application, the data related to other services in the user station 202 is referred to as non-real-time data.

[0157] In an exemplary embodiment, a reporting method of buffer status information is provided, which will be described by taking the user station 202 in Figure 2 as an example, comprising the following steps:

[0158] The buffer status information of the user station and the real-time data to be sent are sent to the management station on the first wireless resource for transmitting real-time data issued by the management station; the first wireless resource is a periodic wireless resource.

[0159] In the embodiment, the management station can configure a periodic wireless resource (referred to as a first wireless resource in the following embodiment) for the user station in advance, for transmitting real-time data. In the process of transmitting real-time data from the user station to the management station, if there is buffer status information to be sent at present, the buffer status information to be sent and the real-time data can be sent to the management station in the first wireless resource. The buffer status information is used to represent the quantity information of the data to be sent in the terminal uplink buffer. In an example, the buffer status information can be the buffer index carried in the value field of the BSR.

[0160] Further, after the management station receives the buffer status information from the first wireless resource, the second wireless resource for transmitting non-real-time data can be allocated to the user station based on the buffer status information, and the second wireless resource is non-periodic. In an exemplary embodiment, the method can further include:

[0161] The second wireless resource allocated to the user station by the management station is received, and non-real-time data is transmitted on the second wireless resource, and the second wireless resource is confirmed by the management station according to the buffer status information.

[0162] The reporting method of the above buffer status information, the management station can issue a periodic wireless resource for transmitting real-time data to the user station in advance, and the user station can periodically send the buffer status information and the real-time data directly to the management station on the periodic wireless resource, so as to obtain the wireless resource for transmitting non-real-time data through the buffer status information. Since the buffer status information is directly sent to the management station through the periodic wireless resource, the process of reporting the buffer status information is simplified, the communication delay is reduced, and the communication quality is improved.

[0163] In an exemplary embodiment, the buffer status information of the user station and the real-time data to be sent are sent to the management station on the first wireless resource for transmitting real-time data issued by the management station, which can include the following steps:

[0164] According to the buffer status information of the user station and the real-time data to be sent, the target real-time data including the buffer status information is determined, and the target real-time data is sent to the management station on the first wireless resource for transmitting real-time data issued by the management station.

[0165] In the embodiment, the buffer status information of the user station can be carried in the real-time data to be sent to obtain the target real-time data, and the target real-time data is sent to the management station on the first wireless resource for transmitting the real-time data, as shown in FIG. 4.

[0166] After the management station receives the target real-time data, the buffer status information and the real-time data can be parsed from the target real-time data, and the second wireless resource is allocated for the user station based on the buffer status information, and then the user station transmits the non-real-time data (other service data) based on the allocated second wireless resource.

[0167] By using the buffer status information reporting method provided in the embodiments of the present application, the user station can send the buffer status information to the management station by carrying the buffer status information in the real-time data. Since the real-time data is data reported to the management station on the pre-configured periodic wireless resource, the user station can directly send the buffer status information to the management station through the periodic wireless resource, which simplifies the process of reporting the buffer status information, reduces the communication delay, and improves the communication quality.

[0168] Referring to FIG. 5, the data structure of the target real-time data is shown. The target real-time data includes a type field, a control information field and a real-time data field. The type field is used to carry the type identifier of the control information, the control information field is used to carry the control information, and the real-time data field is used to carry the real-time data to be sent. The buffer status information can be one of the control information. In fact, the control information can also include channel state information, power margin and other information. The embodiments of the present application do not make specific limitations on the control information.

[0169] In order to alleviate the invalid occupation of resources by the control information and improve the resource utilization, the period and the offset of the user station for sending the buffer status information can be pre-configured. The offset is used to indicate the start of the first wireless resource for reporting the buffer status information, and the period is the reporting period of the buffer status information. Both the period and the offset are set for the first wireless resource. According to the period and the offset, the reporting resource for sending the buffer status information can be determined from the first wireless resource. Referring to FIG. 6, the above determining the target real-time data according to the buffer status information of the user station and the real-time data to be sent can include the following steps 602 to 604, wherein:

[0170] Step 602: determining the reporting resource of the buffer status information according to the period and the offset corresponding to the user station;

[0171] Step 604: if the current first wireless resource for sending the real-time data to the management station is the reporting resource, determining the target real-time data according to the buffer status information of the user station and the real-time data to be sent.

[0172] In the embodiments of the present application, the reporting resource of the buffer status information can be determined from the periodic wireless resource corresponding to the user station and the offset. For example, the periodic wireless resource is the second periodic wireless resource when the offset is 1, and the reporting resource of the buffer status information can be the second+2k periodic wireless resource, where k is an integer greater than or equal to 0. For example, the reporting resource is shown in FIG. 7.

[0173] If the periodic wireless resource currently used for transmitting real-time data is the reporting resource of the buffer status information, the current buffer status information of the user station can be obtained. After the buffer status information and the real-time data are constructed into target real-time data, the target real-time data is transmitted to the management station through the periodic wireless resource.

[0174] For example, the periodic wireless resource currently used for transmitting real-time data is the first periodic wireless resource in the first reporting period of the real-time data, and the buffer status information is not reported. In the second reporting period of the real-time data, the periodic wireless resource currently used for transmitting real-time data is the second periodic wireless resource, and the buffer status information and the real-time data are constructed into target real-time data, which is transmitted to the management station through the second periodic wireless resource. In the third reporting period of the real-time data, the periodic wireless resource currently used for transmitting real-time data is the third periodic wireless resource, and the buffer status information is not reported.

[0175] In one example, the real-time data can carry not only the buffer status information but also other control information in addition to the buffer status information. Therefore, before the buffer status information is reported through the first wireless resource, it is necessary to determine whether the first wireless resource is also used to report other control information. According to the buffer status information of the terminal and the real-time data to be transmitted, the target real-time data can be determined, which can include the following steps 802 to 804, as shown in FIG. 8.

[0176] In step 802, if the first wireless resource currently used for transmitting real-time data to the management station is the reporting resource of other control information in addition to the buffer status information, the reporting priorities of the buffer status information and the other control information are compared.

[0177] In step 804, if the reporting priority of the buffer status information is higher than that of the other control information, the target real-time data is determined according to the buffer status information of the user station and the real-time data to be transmitted.

[0178] In the embodiments of the present application, the reporting priorities of the control information can be preset, and the control information with higher reporting priority is reported preferentially. If the first wireless resource currently used for sending real-time data to the management station is also the reporting resource of the control information other than the buffer status information, the reporting priorities of the buffer status information and the other control information are compared, and when the reporting priority of the buffer status information is higher than that of the other control information, the buffer status information of the subscriber station and the real-time data to be transmitted are constructed into target real-time data.

[0179] The data structure of the target real-time data can refer to that shown in FIG. 9. At this time, the type identification carried in the type field includes the buffer status identification (for example, 2), and the control information carried in the control information field includes the buffer status information of the terminal (indicated as BS (Buffer Status) in FIG. 9). It is preset that the type identification and the control information jointly occupy n bytes, and if the buffer status information and the buffer status identification are less than n bytes, padding is used for filling.

[0180] In another embodiment, determining the target real-time data according to the buffer status information of the terminal and the real-time data to be transmitted can include the following steps:

[0181] If the first wireless resource currently used for sending real-time data to the management station is the reporting resource of the control information other than the buffer status information, the target real-time data is determined according to the buffer status information, the other control information and the real-time data to be transmitted; wherein the type identification of the target real-time data includes the combined type identification corresponding to the buffer status information and the other control information, and the control information of the target real-time data includes the buffer status information and the other control information of the subscriber station.

[0182] In the embodiments of the present application, if it is determined that the first wireless resource currently used for sending real-time data to the management station is also the reporting resource of the other control information, the buffer status information and the other control information can be reported in combination, that is, the buffer status information and the other control information are carried in the real-time data at the same time to obtain the target real-time data.

[0183] The data structure of the target real-time data can refer to FIG. 10. At this time, the type identifier carried in the type field includes a combined type identifier corresponding to the buffer status information and other control information, and the control information carried in the control information field includes the buffer status information and other control information of the terminal. For example, taking the power margin as the other control information, the combined type identifier corresponding to the buffer status information and the power margin can be set as 1, that is, when the type identifier carried in the type field is 1, it can be determined that the control information carried in the control information field includes the buffer status information and the power margin information of the user station. In the embodiment of the application, the type identifier and the control information jointly occupy n bytes, and if the combined type identifier and the buffer status information and the power margin information are less than n bytes, padding is used for filling.

[0184] In the embodiment of the application, the user station can periodically report the buffer status information through the first wireless resource, or can send the BSR to the management station in response to the trigger of the BSR. Referring to FIG. 11, the above method can further include steps 1102 to 1104, wherein:

[0185] Step 1102, triggering the buffer status report BSR;

[0186] Step 1104, if the first wireless resource for sending the real-time data to the management station currently exists, performing the step of sending the buffer status information of the user station and the real-time data to be sent to the management station on the first wireless resource for transmitting the real-time data issued by the management station.

[0187] In the embodiment of the application, the trigger of the BSR can include but is not limited to the following modes: the uplink data buffer of the user station is empty and new data arrives, high-priority data arrives, the user station periodically updates its own buffer status to the management station, etc.

[0188] When the BSR is triggered, if the first wireless resource for sending the real-time data to the management station currently exists, the target real-time data including the buffer status information can be obtained by carrying the buffer status information of the user station in the real-time data to be sent, and the target real-time data is sent to the management station on the first wireless resource. In this way, the buffer status information of the user station can be reported to the management station through the periodic wireless resource, which enriches the reporting mode of the buffer status information, so that when the user station cannot transmit the BSR, the buffer status information can be directly sent to the management station through the periodic wireless resource, the process of reporting the buffer status information is simplified, the communication delay is reduced, and the communication quality is improved.

[0189] In another example, when the BSR is triggered, if the first wireless resource for sending real-time data to the management station does not exist, i.e., the current is not the reporting period of real-time data, the BSR can be sent to the management station through the uplink resource (also referred to as target wireless resource in the embodiment of the application, which is the second wireless resource configured by the management station for the user station in the historical allocation process) for transmitting other service data (non-real-time data). For example, the above method can further include:

[0190] If the first wireless resource for sending real-time data to the management station does not exist, but the target wireless resource for sending non-real-time data to the management station exists, the BSR is sent to the management station on the target wireless resource, which is the second wireless resource issued by the management station for the user station in the historical allocation process.

[0191] In an exemplary embodiment, sending the BSR to the management station on the target wireless resource can include: if the target wireless resource satisfies the BSR sending condition, sending the BSR to the management station on the target wireless resource, the BSR sending condition includes: the empty amount of the target wireless resource is sufficient to send non-real-time data and the BSR, or the empty amount of the target wireless resource is insufficient to send non-real-time data.

[0192] In the embodiment of the application, when the BSR is triggered and the BSR is sent to the management station through the target wireless resource, the following cases are included: case 1, the empty amount of the target wireless resource is sufficient to send complete non-real-time data and the BSR, then the non-real-time data and the BSR can be sent to the management station through the target wireless resource; case 2, the empty amount of the target wireless resource is sufficient to send complete non-real-time data, but insufficient to send complete non-real-time data and the BSR, then the sending of the BSR is abandoned; case 3, if the empty amount of the target wireless resource is insufficient to send complete non-real-time data, then part of the non-real-time data and the BSR can be sent to the management station through the target wireless resource.

[0193] The reporting method of the buffer status information proposed in the embodiment of the application carries the buffer status information of the user station on the periodic wireless resource allocated for real-time data, so that the buffer status information can be quickly transmitted to the management station when the user station cannot normally transmit the BSR. Compared with the existing SR request resource mode, the communication interaction process is simplified and the transmission delay is reduced.

[0194] In an exemplary embodiment, after the management station receives the buffer status information and real-time data of the user station on the first wireless resource configured for the user station, the management station can allocate wireless resources for the user station based on the buffer status information. As shown in FIG. 12, the embodiment of the application provides a resource allocation method, which is applied to the management station 204 in FIG. 2 as an example, including the following steps 1202 to 1204. Among them:

[0195] Step 1202, receiving the buffer status information and real-time data of the user station on the first wireless resource configured for the user station, the first wireless resource being a periodic wireless resource;

[0196] Step 1204, allocating a second wireless resource for the user station according to the buffer status information, the second wireless resource being used for transmitting non-real-time data.

[0197] In the resource allocation method provided by the embodiment, the user station can report the buffer status information and real-time data to the management station on the first wireless resource configured for the user station in advance, so that when the user station cannot transmit the BSR, the buffer status information can be directly sent to the management station through the first wireless resource, the process of reporting the buffer status information is simplified, the management station can timely allocate the wireless resource for the user station, the communication delay is reduced, and the communication quality is improved.

[0198] In an exemplary embodiment, the management station receives the target real-time data sent by the user station on the first wireless resource configured for the user station in advance, the data structure of the target real-time data is shown in FIG. 5, the management station can obtain the type identifier from the type field of the received target real-time data, when the type identifier is an identifier representing that the buffer status information is carried in the control information field, for example, the type identifier is the buffer status identifier or the combined type identifier corresponding to the buffer status information and other control information, the buffer status information can be obtained from the control information field of the target real-time data. For example, as shown in FIG. 13, in step 1204, receiving the buffer status information and real-time data of the user station on the first wireless resource configured for the user station can include the following steps 1302 to 1306, wherein:

[0199] Step 1302, receiving the target real-time data on the first wireless resource configured for the user station;

[0200] Step 1304, obtaining the type identifier from the type field of the target real-time data;

[0201] Step 1306, if the type identifier represents that the control information field carries the buffer status information, obtaining the buffer status information from the control information field of the target real-time data and obtaining the real-time data from the real-time data field of the target real-time data.

[0202] In the embodiment of the present application, if the type identifier is the buffer status identifier, the management station can directly obtain the buffer status information from the control information field of the target real-time data; or if the type identifier is the buffer status identifier or the combined type identifier of the buffer status information and other control information, the buffer status information can be obtained from the position of the buffer status information in the control information field based on the pre-set order of the buffer status information and the other control information in the combined type.

[0203] In an exemplary embodiment, in order to prevent the user station from having no way to send the buffer status information to the management station in the stage without real-time data transmission, the management station cannot allocate the wireless resource for the user station, and the user station cannot transmit other service data to the management station, a timer can be added at the management station side, and after the timer expires, the resource is allocated to the user station by polling. Referring to FIG. 14, the above method can further include the following steps 1402 to 1406, wherein:

[0204] In step 1402, if the buffer index of the user station is 0, the timer is started for the user station.

[0205] In step 1404, the timer is restarted or stopped according to the data sent by the user station.

[0206] In step 1406, if the timer expires, the second wireless resource is allocated to the user station.

[0207] In the embodiment of the present application, the management station can maintain the buffer index of the user station based on the buffer status information reported by the user station and the resource allocation. When the user station successfully enters the network and / or the buffer index of the user station is 0, it can be considered that the management station does not know the resource requirement of the user station at this time, and then the timer is started for the user station, and after the timer expires, the user station is added to the list of user stations to be allocated resources, and the second wireless resource is allocated to the user stations in the list of user stations to be allocated resources by polling.

[0208] After the management station receives the data sent by the user station, whether to restart or stop the timer can be determined based on the data sent by the user station. In an exemplary embodiment, in step 1404, the timer is restarted or stopped according to the data sent by the user station, which can include: if the data sent by the user station satisfies the restart condition, the timer is restarted for the user station, or if the data sent by the user station satisfies the stop condition, the timer is stopped for the user station, wherein the restart condition includes: the data does not contain the buffer status information, or the data contains the buffer status information and the buffer status information is 0; and the stop condition includes: the data contains the buffer status information and the buffer status information is not 0.

[0209] In the embodiment of the present application, the following several situations are included:

[0210] Case 1: the data received by the management station does not contain the buffer status information, it can be considered that the user station has no resource allocation requirement, and thus the buffer status information is not sent, and thus if the timer is running at this time, the timer is restarted, and the next round of timing is restarted;

[0211] Case 2: the data received by the management station contains the buffer status information, and the buffer status information is 0, it can be considered that the user station currently has no resource allocation requirement, and thus if the timer is running at this time, the timer is restarted, and the next round of timing is restarted. It should be noted that if the user station has multiple buffer status information, all of which need to be 0, the timer is restarted;

[0212] Case 3: the data received by the management station contains the buffer status information, and the buffer status information is not 0, it can be considered that the user station currently has resource allocation requirement, and the wireless resource allocation is performed for the user station based on the buffer status information, and thus the timer can be stopped at this time until the buffer index of the user station is 0, and the timer is started again for the user station.

[0213] In another embodiment, the timer can also be updated according to the updated buffer index after the management station performs the wireless resource allocation for the user station based on the buffer status information and updates the buffer index maintained by the user station. Referring to FIG. 15, the timer is restarted or stopped according to the data sent by the user station in step 1404, which can include the following steps 1502 to step 1504, wherein:

[0214] Step 1502, updating the buffer index of the user station according to the buffer status information sent by the user station;

[0215] Step 1504, if the buffer index of the user station is 0, restarting the timer.

[0216] In the embodiment of the application, the management station can update the buffer index of the user station after performing the wireless resource allocation for the user station according to the buffer status information sent by the user station, or the buffer index of the user station can be updated first according to the buffer status information sent by the user station, and then the resource allocation is performed based on the updated buffer index, and the buffer index of the user station is updated according to the resource allocation. If the updated buffer index of the user station is 0, it can be considered that the management station does not know the resource requirement of the user station at this time, and thus the timer is started / restarted for the user station, and a new round of timing is started.
