BSR reporting method, device, terminal equipment, network side equipment and medium

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202311670358.0 filed in China on December 6, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a BSR reporting method, apparatus, terminal equipment, network-side equipment, and medium. Background Art

[0004] When a terminal device needs to send data to the network, it requires uplink Radio Bearer (RB) resources. If RB resources are not available, it must first request RB resources from the network. Currently, the terminal can request RB resources by sending a Buffer Status Report (BSR) to the network.

[0005] In the related art, a terminal inserts a BSR control unit into the Protocol Data Unit (PDU) of the Medium Access Control (MAC) layer, and indicates to the network device through the BSR control unit the Logical Channel Group (LCG) and the amount of data to be sent, thereby requesting the network device to allocate RB resources. However, in the 1-byte payload of the short BSR or short truncated BSR in the New Radio (NR), the LCG ID (identity) indicating the LCG occupies 3 bits. For a terminal configured with a single LCG (such as an A-IoT device), if 3 bits are used to indicate the LCG ID, only 5 bits will be left to indicate the amount of cached data, resulting in low quantization accuracy of the cached data amount, thereby wasting transmission resources.

[0040] The following explains the concepts, nouns / terms or coined words involved in the embodiments of this application.

[0041] 1. Ambient power-enabled IoT (A-IoT)

[0042] A-IoT, also known as Ambient IoT (Ambient Power-Enabled Internet of Things), is an IoT service in which IoT devices (such as IoT terminals) are powered by energy harvesting. IoT devices lack batteries or have limited energy storage capabilities (for example, a capacitor). Energy harvesting can be achieved through radio waves, light, motion, heat, or other suitable energy sources.

[0043] Understandably, these IoT devices have low overall power consumption, including low-power signal reception and low-power signal transmission. Due to their low overall power consumption, communication energy can come from environmental sources such as wind, kinetic energy, thermal energy, and RF signals. These devices are also known as ambient IoT devices, passive IoT devices, or transponder devices.

[0044] Ambient IoT devices can be categorized based on energy source, energy storage capability, passive or active emission, etc.

[0045] According to TR22.840, A-IoT has the following passive or active transmission modes:

[0046] Normal operation: A-IoT devices have power to operate continuously or for a period of time. This power can come from continuous energy harvesting or have a certain energy storage capability, such as capacitors.

[0047] Active transmission supports device-triggered operations. The device can only be active for short periods of time, allowing intermittent communication. The device can decide when to communicate with the network. It does not necessarily monitor the network, meaning it may not monitor called services for extended periods.

[0048] Passive transmission only supports on-demand operations initiated by the network. The device cannot initiate services on its own.

[0049] Figures 3A to 3C are schematic diagrams of the network structure of the A-IoT involved in the embodiments of the present application. In the network structure shown in Figure 3A, the reader / writer can be integrated into the base station as a functional unit, and the base station can communicate directly with the A-IoT device; in the network structure shown in Figure 3B, the reader / writer can be integrated into the base station as a functional unit, and the base station communicates with the A-IoT device through an auxiliary node such as a repeater NCR node or a RIS node. In the network structure shown in Figure 3C, the reader / writer is a unit deployed separately from the base station, and the A-IoT device involved can be a terminal device based on passive communication, or a fixed deployment reader / writer device controlled by the base station, and the reader / writer device communicates with the A-IoT device under the control of the base station. The communication between the reader / writer and the A-IoT device can be based on a backscatter communication mechanism, or it can be based on an active communication method in which the A-IoT device generates and transmits radio waves by itself.

[0050] 2. BSR

[0051] A BSR is a data buffer status report (BSR) that notifies network equipment of the amount of data waiting to be transmitted in a terminal's buffer. When a terminal wants to send data, it first stores the processed data in a buffer and then requests uplink radio resources from the network by sending a data buffer status report. At the MAC layer, the base station allocates the minimum number of uplink grants, or PUSCH (Physical Uplink Shared Channel) resources, to the terminal based on the priority, service level, and data size of the data to be transmitted, as well as the available radio resources in the cell.

[0052] In 5G networks, each logical channel (LCH) is assigned to a logical channel group via an LCG. A UE can be configured with up to eight LCGs. The data volume calculation process of the MAC entity in TS 38.322 [3] and [4] is determined by the UL data volume available for the logical channel.

[0053] Rel-15 BSRs include the following types:

[0054] (1) Regular BSR: Regular BSR is triggered in any of the following situations:

[0055] An LCH with a higher priority than the LCH currently sending data changes from no data to data; or

[0056] When all LCHs have no data to send, one LCH becomes available for transmission; or

[0057] When the BSR retransmission timer (retxBSR-Timer) times out, at least one LCH still has data to be sent.

[0058] (2) Periodic BSR (Periodic BSR), which is triggered when the periodic BSR sending timer (periodicBSR-Timer) times out;

[0059] (3) Padding BSR: It is triggered when a MAC protocol data unit (PDU) has enough space to accommodate a BSR MAC control element (CE) after accommodating all the data.

[0060] It should be noted that each LCH belongs to one LCH group. The BS (buffer size level) of the BSR is reported per LCG, with a maximum of eight LCGs configured. A Regular BSR can trigger the transmission of an SR. If no uplink grant is obtained after the previous SR transmission, an SR retransmission can be triggered.

[0061] NR Rel-15 specifies four BSR formats: Short BSR, Short Truncated BSR, Long BSR, and Long Truncated BSR. Short BSR and Short Truncated BSR consist of 8 bits, 3 of which are used for the LCG ID and 5 for the buffer size. The 5 bits provide 2^5=32 indices from 0 to 31, with index 0 representing a 0-byte BSR and index 31 representing a 150,000-byte BSR. The mapping of these indices is provided (in bytes) in 3GPP 38.321-Table 6.1.3.1-1: Buffer size levels for the 5-bit buffer size field. Long BSR and Long Truncated BSR include multiple (e.g., m+1) MAC CEs, which have the same format but are variable in size. The first byte represents the LCG ID, and the rest represents the buffer status report. Long BSR and Long Truncated BSR use 8 bits to allow 2^8=256 indices, which can accommodate a larger buffer state of 81338368 bytes.

[0062] For regular BSR or periodic BSR, if the terminal has more than one LCG with data, the long BSR is used; otherwise, the short BSR is used.

[0063] Due to the feature of 8 LCGs introduced in NR, for short BSR or short truncated BSR, 3 bits are required to indicate the LCG ID, leaving only 5 bits for indicating the amount of cached data. Therefore, it can only indicate the buffer size corresponding to index 0-31, making the quantization accuracy of the cached data amount lower than the 6-bit indication used in LTE or the 8-bit cached data amount indication used in long BSR or long truncated BSR in NR.

[0064] 3. BSR Report of Narrow Band Internet of Things (NB-IoT) Terminals

[0065] NB-IoT terminals are terminals based on the LTE wireless protocol and only support one LCG (i.e., LCG#0). The buffer size indication contains 6 bits, similar to ordinary LTE terminals, and uses the same quantization table containing 64 entries.

[0066] The BSR reporting method provided in the embodiment of the present application can be applied to the scenario where an A-IoT device performs BSR reporting.

[0067] In related technologies, when an A-IoT device is configured with an LCG, the BSR format used to request uplink resources from the network device can be either a short BSR or a truncated BSR. However, in the NR short BSR or truncated BSR, the LCG ID occupies 3 bits of the 1-byte payload, leaving only 5 bits for buffer information reporting, resulting in a waste of transmission resources.

[0068] The BSR reporting method provided in the embodiment of the present application is that the A-IoT device can determine whether to use a BSR format that does not contain an LCG identifier or a BSR table with a cache indication range smaller than the default table (i.e., a quantization accuracy greater than the default table) to perform BSR reporting based on its own device type, LCG number or configuration information. For example, when the A-IoT device is configured with only one LCG, it can use the first BSR format to perform BSR reporting. Since the BSR format used does not contain an LCG identifier, it avoids occupying the bit load to report the BSR identifier to the network device, thereby saving transmission resources for performing BSR reporting. For another example, when the A-IoT device is an A-IoT device, it can use a BSR table with higher quantization accuracy to perform BSR reporting. Therefore, the A-IoT device can report a cache data amount indication that is closer to the actual cache data amount according to the BSR table, so that the network device can allocate the actual required transmission resources to the A-IoT device based on the cache data amount indication reported by the A-IoT device, thereby saving transmission resources.

[0069] The BSR reporting method provided in the embodiment of the present application is described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.

[0070] FIG2 is a flow chart of a BSR reporting method provided in an embodiment of the present application. As shown in FIG2 , the BSR reporting method may include the following steps S201 and S202:

[0071] Step S201: The terminal device obtains first information.

[0072] In some embodiments, the first information includes at least one of the following:

[0073] The device type of the terminal device;

[0074] The number of logical channel groups (LCGs) of the terminal device;

[0075] The first configuration information is used to indicate whether the terminal device uses the first BSR information to perform BSR reporting.

[0076] Exemplarily, the device type may include an A-IoT device, a read / write device, and the like.

[0077] Exemplarily, the number of LCGs may be 1. When a terminal device is configured with a single LCG, the number of LCGs of the terminal device is 1.

[0078] Exemplarily, the first configuration information is configuration information provided by the first network device.

[0079] In some embodiments, the terminal device is an environment-enabled Internet of Things (A-IoT) device, and the first network device is a base station.

[0080] In some embodiments, the terminal device is a user equipment (UE), and the first network device is a base station.

[0081] Step S202: The terminal device determines whether to use the first BSR information to perform BSR reporting based on the first information.

[0082] In which, the above-mentioned first BSR information includes at least one of a first BSR format and a first BSR table, the above-mentioned first BSR format does not include a logical channel group LCG identifier or the first BSR format only includes a cache data amount indication of a single LCG, the above-mentioned first BSR table includes at least one cache data amount, and the maximum cache data amount of the first BSR table is less than the maximum cache data amount of the default BSR table.

[0083] In some embodiments, the first BSR information is configured or pre-configured by the first network device; or, the number of LCGs is configured, pre-configured or pre-defined by a protocol by the first network device.

[0084] In some embodiments, the first BSR format is a format of a MAC CE for sending a BSR, which may also be referred to as a BSR MAC CE format.

[0085] In some embodiments, the first BSR format is used for a terminal device configured with one LCG to send a BSR report, and the BSR report only includes a buffer data amount indication (i.e., a buffer size indication) of a single LCG but does not include an LCG ID indication. For example, the buffer data amount indication is used to indicate the buffer data amount of the LCG of the terminal device, and may also be referred to as a buffer indication.

[0086] It can be understood that the cache data volume of the LCG of the terminal device is the data volume in the LCG buffer of the terminal device.

[0087] In some embodiments, the first BSR format includes M bit payloads, the M bit payloads include K cache data amount indication bit payloads and MK reserved bit payloads (Reserved Bits), 0<M≤8, 0<K≤M, and M and K are both positive integers.

[0088] It can be understood that the above-mentioned reserved bit load is a reserved bit load.

[0089] Exemplarily, the first BSR format may include an 8-bit payload, which includes 6 cache indication bit payloads and 2 reserved bit payloads, as shown in FIG3A ; or, the first BSR format may include an 8-bit payload, which includes 7 cache indication bit payloads and 1 reserved bit payload; or, the first BSR format may include an 8-bit payload, which is all used for cache indication, as shown in FIG3B .

[0090] It should be noted that the bit load (ie, bit) in the embodiment of the present application can also be referred to as a bit position.

[0091] The first BSR format provided in the embodiment of the present application does not include the LCG ID field. Compared with the short BSR or short truncated BSR of NR and the short BSR or short truncated BSR in LTE, the length of the field used for indicating the amount of cached data can be lengthened, so that the cached data amount indication field can reach 8 bits, thereby improving the accuracy of the cached data amount indication.

[0092] In some embodiments, the first BSR table includes at least one cached data amount. It will be appreciated that the at least one cached data amount constitutes a cached data amount range, which may also be referred to as a cache indication range. In other words, the cache indication range of the first BSR table may be a numerical range between the maximum cache size (i.e., the maximum cached data amount) and the minimum buffer size in the first BSR table. Exemplarily, the cache indication range may be 0 to 10,000 bytes.

[0093] Similarly, the default BSR table includes at least one cached data amount. It will be understood that the at least one cached data amount constitutes a cached data amount range. In other words, the cached data amount range of the default BSR table can be a range of values ​​between the maximum cache area size (i.e., the maximum cached data amount) and the minimum buffer size in the default BSR table. Exemplarily, the cached data amount range can be 0 to 150,000 bytes.

[0094] In some embodiments, the first BSR table includes N cache data amounts, a maximum cache data amount among the N cache data amounts is less than 81338368 bytes, and N is a positive integer less than or equal to 255.

[0095] Exemplarily, the N buffered data amounts may be buffer sizes (BS). Exemplarily, the terminal device may query the BS corresponding to the buffered data amount of the LCG from the first BSR table.

[0096] Exemplarily, the amount of cached data of the terminal device is less than 5 bytes, and the BS in the corresponding first BSR table can be 0 to 5, expressed as 0<BS≤5; the amount of cached data of the terminal device is greater than 110 bytes and less than 120 bytes, and the BS in the corresponding first BSR table can be 110 to 120, expressed as 110<BS≤125.

[0097] In some embodiments, the first BSR table further includes X indexes corresponding to N cached data amounts, and when the index range of the X indexes is 0 to 31, the maximum cached data amount in the first BSR table is less than 150,000; or, when the index range of the first BSR table is 0 to 255, the maximum cached data amount in the first BSR table is less than 81,338,368 bytes, and X is an integer greater than or equal to 0.

[0098] Exemplarily, the maximum buffered data size in the first BSR table may be 5000 bytes, 10000 bytes, or 15000 bytes.

[0099] Exemplarily, each index in the first BSR table corresponds to a cache data amount range, a cache data amount range may include multiple cache data amounts, and each index is used to indicate a cache data amount range of a terminal device.

[0100] It should be noted that the above-mentioned maximum data cache capacity and the cache data capacity corresponding to each index can be set according to actual needs, and the embodiments of the present application do not limit this.

[0101] At present, the existing BSR table that is common to all business data volumes supports cache indication of larger business data volumes. Since the business data volume of A-IoT terminals is generally small, the existing BSR table may not support BSR reporting of A-IoT devices. Or, even if the A-IoT device can use the existing BSR table to perform BSR reporting, the indicated cache data volume size may be much larger than the actual cache data volume size of the A-IoT device, thereby resulting in a waste of transmission resources.

[0102] The first BSR table provided in the embodiment of the present application can indicate a smaller maximum cache data amount than the maximum cache data amount corresponding to the existing 8-bit BSR table, so that the range of the cache data amount corresponding to the BSR table is more consistent with the business data cache data amount of the A-IoT device, so that the quantitative accuracy of the cache report is higher, and the indicated cache data amount size can be closer to the actual data amount size of the A-IoT device, thereby saving transmission resources.

[0103] In some embodiments, the terminal device has a first capability, and the first capability is the capability of performing BSR reporting using a first BSR format.

[0104] For example, the protocol may predefine that the interrupting device of a single LCG is configured to have the capability of using the new BSR MAC CE to perform BSR reporting.

[0105] The BSR reporting method provided by an embodiment of the present application, the terminal device obtains first information, and based on the first information, determines whether to use the first BSR information to perform BSR reporting; wherein the above-mentioned first BSR information includes at least one of a first BSR format and a first BSR table, the above-mentioned first BSR format does not include a logical channel group LCG identifier or the first BSR format only includes a cache data amount indication of a single LCG, the above-mentioned first BSR table includes at least one cache data amount, and the maximum cache data amount of the first BSR table is less than the maximum cache data amount of the default BSR table; the above-mentioned first information includes at least one of the following: a device type of the terminal device; the number of logical channel groups LCG of the terminal device; first configuration information, the first configuration information being used to indicate whether the terminal device uses the first BSR information to perform BSR reporting. Through this method, the terminal device can determine whether to use a BSR format that does not include an LCG identifier or a BSR table with a cache indication range smaller than the default table (i.e., a quantization accuracy greater than the default table) to perform BSR reporting based on its own device type, LCG number or configuration information. Since the BSR format used to perform BSR reporting may not include an LCG identifier, it avoids occupying the bit load to report the BSR identifier to the network device, thereby saving transmission resources for performing BSR reporting; since the terminal device can use a BSR table with higher quantization accuracy to perform BSR reporting, the terminal device can report a cache indication that is closer to the actual cache data amount according to the BSR table, thereby saving transmission resources.

[0106] In some embodiments, the first information includes the device type of the terminal device; the process of step S202 may include the following steps S202a:

[0107] Step S202a: When the device type is an A-IoT device type, the terminal device uses the first BSR information to perform BSR reporting.

[0108] In some embodiments, when the terminal device determines that the device type is the first device type, the terminal device uses the first BSR information to perform BSR reporting.

[0109] In some embodiments, the first device type includes an A-IoT device type.

[0110] Exemplarily, for a terminal device of the first device type, the protocol may predefine that the terminal device of the first device type only supports one LCG. After the terminal device of the first device type accesses the base station, the terminal device may use the above-mentioned first BSR information to perform BSR reporting.

[0111] Exemplarily, the A-IoT device may perform BSR reporting using the first BSR table, or the A-IoT device may perform BSR reporting using the first BSR format.

[0112] In an embodiment of the present application, the A-IoT device can use the first BSR format to perform BSR reporting. Since the first BSR format does not include the LCG ID field, the A-IoT device can use a maximum of 8 bits of payload to indicate the cache data amount, thereby improving the cache indication accuracy; or, the A-IoT device can use the first BSR table to perform BSR reporting, so that the range of the cache data amount corresponding to the BSR table is more closely matched with the service data cache data amount of the A-IoT device, so that the quantitative accuracy of the cache report is higher, and the indicated cache data amount size can be closer to the actual data amount size of the A-IoT device, thereby saving transmission resources.

[0113] In some embodiments, the first information includes the number of logical channel groups (LCGs) of the terminal device; the process of step S202 may include the following steps S202b:

[0114] Step S202b: When the terminal device is configured with a single LCG, the terminal device performs BSR reporting using the first BSR information.

[0115] In some embodiments, when the terminal device determines that the number of LCGs is one, the terminal device uses the first BSR information to perform BSR reporting.

[0116] For example, taking the terminal device as an A-IoT device, when the A-IoT device is configured with an LCG, the A-IoT device can use the first BSR information to perform BSR reporting.

[0117] In some embodiments, the present application provides an LCG configuration method, which may include the following steps S203:

[0118] Step S203: The terminal device receives the second configuration information from the first network device.

[0119] The second configuration information is used to configure a single LCG.

[0120] In some embodiments, the first network device may send second configuration information to the terminal device.

[0121] Exemplarily, the base station may send configuration information (ie, second configuration information) to the A-IoT device to configure a single LCG for the A-IoT device.

[0122] In an embodiment of the present application, the base station can configure a single LCG for the A-IoT device so that the MAC layer data of the A-IoT device can be sent through one LCG. Since the A-IoT device is only configured with one LCG, when the A-IoT device performs BSR reporting, it can use the first BSR format that does not include the LCG ID field for reporting, thereby being able to use more bit loads to indicate the amount of cached data and improve the indication accuracy.

[0123] In some embodiments, the above step S203 may be performed before the above step S201 or simultaneously with the above step S201.

[0124] In some embodiments, the present application provides a capability reporting method, which may include the following steps S204:

[0125] Step S204: The terminal device sends first capability information to the first network device.

[0126] The first capability information is used to indicate that the terminal device has a first capability, which is the capability of using a first BSR format to perform BSR reporting.

[0127] For example, taking the terminal device as an A-IoT device, the A-IoT device can report the first capability information to the base station, and the base station can instruct the A-IoT device to perform BSR reporting using the first BSR format based on the first capability information.

[0128] In an embodiment of the present application, the terminal device can report to the base station that it has the ability to perform BSR reporting using the first BSR format. The base station can instruct the terminal device to use the first BSR format to perform BSR reporting if the terminal device has the ability, thereby avoiding the network device making invalid instructions when the terminal device does not have the corresponding ability, thereby saving wireless resources.

[0129] In some embodiments, the above step S204 may be performed before the above step S201 or simultaneously with the above step S201.

[0130] In some embodiments, the BSR reporting method provided in the embodiments of the present application may include the following steps S205 to S207:

[0131] Step S205: The terminal device determines the first index corresponding to the cached data volume of the LCG based on the second BSR table.

[0132] The second BSR table is the first BSR table, or a default BSR table.

[0133] Step S206: The terminal device sends a first BSR report to the first network device using the first BSR format.

[0134] The first BSR report carries a first index, and the first index is used to indicate the amount of cached data of the LCG.

[0135] Step S207: The first network device receives a first BSR report from the terminal device.

[0136] Exemplarily, after receiving the first BSR report, the first network device determines the cache information of the terminal device according to the first BSR report.

[0137] Exemplarily, the first BSR report may be a first BSR MAC CE.

[0138] In some examples, when a terminal device is configured with a single LCG, when performing a BSR report, it can determine a buffered data volume (BS) that matches the buffered data volume of the single LCG from a first BSR table or a default BSR table, and send a BSR report carrying an index (i.e., a first index) corresponding to the matching buffered data volume using a first BSR format. Exemplarily, the index can occupy up to 8 bits of the BSR MAC CE payload.

[0139] For example, taking the terminal device as an A-IoT device, when the A-IoT device is configured with a single LCG, the A-IoT device can determine the cached data amount that matches the cached data amount of the single LCG from the first BSR table, and send the index corresponding to the matching cached data amount through the second BSR report using the first BSR format. Exemplarily, the index can occupy 8 bits of the second BSR report.

[0140] Exemplarily, in combination with the above embodiments, taking the terminal device as a UE as an example, when the UE is configured with a single LCG, the UE can determine the cached data amount that matches the cached data amount from the default BSR table, and use the first BSR format to send the index corresponding to the cached data amount through the second BSR report.

[0141] In other examples, when the terminal device receives an instruction (i.e., first configuration information) to perform BSR reporting using a first BSR format, when performing BSR reporting, it determines the cache data amount (BS) that matches the cache data amount from the first BSR table or the default BSR table, and sends a BSR report carrying an index corresponding to the cache data amount using the first BSR format.

[0142] For example, taking the terminal device as an A-IoT device, when the A-IoT device receives an instruction to perform BSR reporting using the first BSR format, the A-IoT device can determine the cached data amount that matches the cached data amount from the first BSR table, and send the index corresponding to the cached data amount through the second BSR report using the first BSR format.

[0143] In an embodiment of the present application, the terminal device can determine the cache data amount indication (i.e., the first index) based on the first BSR table or the default BSR table, and use the first BSR format to send a BSR report carrying the index corresponding to the cache data amount. Since the first BSR format does not include the LCG ID field, the terminal device can use up to 8 bits to send the cache data amount indication, so that the indicated cache data amount size can be closer to the actual data amount size of the terminal device, thereby improving the indication accuracy.

[0144] In some embodiments, the BSR reporting method provided in the embodiments of the present application may include the following steps S208 and S210:

[0145] Step S208: The terminal device determines the second index corresponding to the cached data volume of the LCG based on the first BSR table.

[0146] Step S209: The terminal device sends a second BSR report to the first network device.

[0147] Step S210: The first network device receives a second BSR report from the terminal device.

[0148] The second BSR report carries a second index, and the second index is used to indicate the amount of cached data of the LCG.

[0149] In some examples, when a terminal device is configured with a single LCG, when performing BSR reporting, it can determine the cache data amount that matches the cache data amount from the first BSR table, and send the index corresponding to the cache data amount (i.e., the second index) through the second BSR report.

[0150] For example, taking the terminal device as an A-IoT device, when the A-IoT device is configured with a single LCG, the A-IoT device can determine the cached data volume that matches the cached data volume from the first BSR table, and send the index corresponding to the cached data volume through the second BSR report.

[0151] Exemplarily, in combination with the above embodiments, taking the terminal device as UE as an example, when the UE is configured with a single LCG, the UE can determine the cached data amount that matches the cached data amount from the first BSR table, and send the index corresponding to the cached data amount through the second BSR report.

[0152] In other examples, when the terminal device receives an instruction (i.e., first configuration information) to perform BSR reporting using a first BSR table, when performing BSR reporting, it determines the cache data amount that matches the cache data amount from the first BSR table, and sends the index corresponding to the cache data amount through a second BSR report.

[0153] For example, taking the terminal device as an A-IoT device, when the A-IoT device receives an instruction to perform BSR reporting using the first BSR table, the A-IoT device can determine the cached data amount that matches the cached data amount from the first BSR table, and send the index corresponding to the cached data amount through the second BSR report.

[0154] In an embodiment of the present application, the terminal device can determine the cache data amount indication (i.e., the second index) based on the first BSR table. Since the cache indication range of the first BSR table is smaller than the cache indication range of the default table, the cache data amount range corresponding to the BSR table is more closely matched with the business data cache data amount of the terminal device with a smaller business data amount (such as an A-IoT device), so that the quantitative accuracy of the cache report is higher, and the indicated cache data amount size can be closer to the actual data amount size of the terminal device, thereby saving transmission resources.

[0155] The BSR reporting method provided in the embodiment of the present application may include the following steps A1:

[0156] Step A1: The terminal device uses the first BSR information to perform BSR reporting.

[0157] Among them, the above-mentioned first BSR information includes at least one of a first BSR format and a first BSR table, the above-mentioned first BSR format does not include an LCG identifier or the first BSR format only includes a cache data amount indication of a single LCG, the above-mentioned first BSR table includes at least one cache data amount, and the maximum cache data amount of the above-mentioned first BSR table is less than the maximum cache data amount of the default BSR table.

[0158] It should be noted that the explanation of this embodiment can be found in the description of the above embodiment, which will not be repeated here.

[0159] In an embodiment of the present application, the terminal device may perform BSR reporting using a BSR format that does not include an LCG identifier or a BSR table whose cache indication range is smaller than the default table (i.e., the quantization accuracy is greater than the default table). Since the BSR format used to perform BSR reporting may not include an LCG identifier, it avoids occupying the bit load to report the BSR identifier to the network device, thereby saving transmission resources for performing BSR reporting; alternatively, the terminal device may use the first BSR table to perform BSR reporting. Since the quantization accuracy of the first BSR table is higher, the terminal device can report a cache indication that is closer to the actual cache data amount according to the BSR table, thereby saving transmission resources.

[0160] FIG4 is a flow chart of a BSR reporting method according to an embodiment of the present application. As shown in FIG4 , the BSR reporting method may include the following steps S301 to S303:

[0161] Step S301: The terminal device sends a BSR report to the first network device.

[0162] Step S302: The first network device receives a BSR report from the terminal device, where the BSR report is determined and sent based on first BSR information.

[0163] Step S303: The first network device determines the cache information of the terminal device according to the BSR report.

[0164] Among them, the above-mentioned first BSR information includes at least one of the first BSR format and the first BSR table, the above-mentioned first BSR format does not include the logical channel group LCG identifier or the first BSR format only includes the cache data amount indication of a single LCG, and the cache indication range of the above-mentioned first BSR table is smaller than the cache indication range of the default BSR table.

[0165] In some embodiments, the BSR report may be the first BSR report or the second BSR report described above.

[0166] In some embodiments, the BSR report carries an index, which is used to indicate the amount of cached data of the terminal device.

[0167] In some embodiments, after receiving the BSR report, the first network device may determine the amount of cached data (ie, cached information) of the terminal device according to the index carried in the BSR report.

[0168] It should be noted that, for the explanation of the first BSR format and the first BSR table, reference may be made to the description of the above embodiment, which will not be repeated here.

[0169] Step S303: The first network device determines the cache information of the terminal device according to the BSR report.

[0170] In an embodiment of the present application, the first network device can receive a BSR report from the terminal device, and the BSR report is determined based on at least one of the first BSR format and the first BSR table. The first BSR format may not include an LCG identifier, thereby avoiding occupying the bit load to report the BSR identifier to the network device, thereby saving transmission resources for executing the BSR report; since the quantization accuracy of the first BSR table is higher, the terminal device can report a cache indication that is closer to the actual cache data amount according to the BSR table, so that the first network device can allocate the transmission resources required to transmit the actual cache data to the terminal device based on the cache indication, thereby saving transmission resources.

[0171] In some embodiments, the above step S302 may include the following steps S302a, and the above step S301 may include the following steps S301a:

[0172] Step S301a: The terminal device sends a first BSR report to the first network device.

[0173] Step S302a: The first network device receives a first BSR report from the terminal device.

[0174] Among them, the above-mentioned first BSR report is sent based on the first BSR format, and the above-mentioned first BSR report carries the first index corresponding to the cache data amount of LCG. The above-mentioned first index is determined based on the second BSR table. The above-mentioned second BSR table is the first BSR table, or the default BSR table.

[0175] In some embodiments, the above step S302 may include the following step S302b, and the above step S301 may include the following step S301b:

[0176] Step S301b: The terminal device sends a second BSR report to the first network device.

[0177] Step S302b: The first network device receives a second BSR report from the terminal device.

[0178] The second BSR report carries a second index corresponding to the amount of cached data of the LCG, and the second index is determined based on the first BSR table.

[0179] It should be noted that for the explanation of this embodiment, please refer to the description of the above embodiment, which will not be repeated here.
