Description

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

Technical Field

The application belongs to the technical field of communication, and particularly relates to a BSR reporting method, a BSR reporting device, terminal equipment, network side equipment and a medium.

Background

When the terminal equipment needs to send data to the network side, an uplink Radio Bearer (RB) resource needs to exist, and if no RB resource exists, the RB resource needs to be applied to the network side equipment first. Currently, the terminal may apply for RB resources by sending a buffer status report (Buffer Status Report, BSR) to the network side device.

In the related art, a terminal requests a network side device to allocate RB resources by inserting a BSR control unit in a protocol data unit (Protocol Data Unit, PDU) of a medium access control layer (Medium Access Control, MAC) and indicating a logical channel group (Logical Channel Group, LCG) and a data amount of data to be transmitted to the network side device through the BSR control unit. However, in a short BSR or a 1-byte payload of a short truncated BSR in a New Radio, NR, an LCG ID (identity) indicating LCG occupies 3 bits, and for a terminal (e.g., a-IoT device) configured with a single LCG, if the LCG ID is indicated by using 3 bits, only 5 bits are left for indicating the buffered data amount, resulting in low quantization accuracy of the buffered data amount and thus waste of transmission resources.

Concepts, nouns/terms or self-explanatory words involved in the embodiments of the present application are explained below.

1. Environmental energy enabled internet of things (a-IoT)

A-IoT, which may also be referred to as an Ambient IoT, i.e., an environment-energy enabled internet of things, english collectively referred to as Ambient power-enabled Internet of Things (Ambient power-enabled IoT), is an IoT service in which IoT devices (e.g., ioT terminals) are powered by energy harvesting (ENERGY HARVESTING), have no battery, or have limited energy storage capacity (e.g., use of a capacitor). The energy source for energy harvesting includes radio waves, light, motion, heat, or other suitable energy source.

It is appreciated that the overall power consumption of such IoT devices is low, including low power consumption signal reception and low power consumption signal transmission. Because of the low overall power consumption, the energy of the communication may originate from the environment, e.g., wind energy, kinetic energy, thermal energy, radio frequency RF signals, etc., and may also be referred to as an Ambient IoT device, a passive IoT device, or a reply device, etc.

The Ambient IoT devices may be categorized based on energy source (energy source), energy storage capability (energy storage capability), passive (Passive) or Active (Active) emissions, and so on.

Referring to TR22.840, passive (Passive) or Active (Active) transmission of a-IoT has a number of communication modes:

and (5) normal operation. Wherein the a-IoT device has power to operate continuously or for a period of time. The energy may come from a continuous energy harvesting or may be provided with some energy storage capacity, e.g. equipped with a capacitor.

And actively transmitting, and supporting the operation triggered by the equipment. Wherein the device can only support short periods of active state, supporting intermittent communication. The device may decide when to communicate with the network. The device does not have to monitor the network, i.e. may not monitor the called traffic for a long time.

Passive transmission only supports network initiated on-demand operation. Wherein the device cannot initiate the service itself.

In one network structure of the A-IoT, the reader-writer can be integrated in the base station as a functional unit, the base station can be directly communicated with the A-IoT device, in the other network structure, the reader-writer can be integrated in the base station as a functional unit, the base station can be communicated with the A-IoT device through auxiliary nodes such as a repeater NCR node or an RIS node, and in the other network structure, the reader-writer is used as a unit which is arranged separately from the base station, wherein the A-IoT device can be a terminal device based on passive communication or a fixedly arranged reader-writer device controlled by the base station, and the reader-writer device realizes communication with the A-IoT device under the control of the base station. The communication between the reader and the a-IoT device may be based on a backscatter communication mechanism, or may be based on an active communication manner in which the a-IoT device generates the transmit electric waves by itself.

2、BSR

The BSR is a data buffer report for informing the network-side device of the size of the amount of data waiting to be transmitted in the buffer of the terminal. When the terminal needs to send data, firstly, the processed data is stored in a Buffer, and then the uplink wireless resource is applied to the network by sending a data Buffer status report. The base station allocates a minimum amount of Uplink grant, namely Uplink Physical shared channel (SHARED CHANNEL, PUSCH) resources, to the terminal according to the priority, service level, data size and the like of the data to be transmitted by the terminal at the MAC layer and according to the condition of the wireless resource of the cell.

Each Logical Channel (LCH) is allocated to one Logical Channel group through an LCG in the 5G network, and the UE can configure 8 LCGs at most. The data amount calculation procedure of the MAC entity in TS 38.322[3] and [4] is determined by the UL data amount available for the logical channel.

In Rel-15 BSR there are BSRs of the following types:

(1) Conventionally BSR (Regular BSR), the Regular BSR triggers in any case:

LCH with higher priority than LCH currently having data transmission changes from no data transmission to having data transmission, or

One LCH becomes data-sent when all LCHs do not have data to send, or

At least one LCH has data to transmit when a BSR retransmission Timer (retxBSR-Timer) expires.

(2) Periodically BSR (Periodic BSR), triggering a Periodic BSR when a Periodic BSR transmission Timer (periodicBSR-Timer) times out;

(3) The addition BSR (Padding BSR) is triggered when one MAC protocol data unit (Protocol Data Unit, PDU) has a remaining capacity to accommodate a BSR MAC Control Element (CE) after accommodating all data.

Note that, one LCH belongs to one LCH group, BS (buffer size level) of the BSR is reported in LCG units, and at most 8 LCGs may be configured. The Regular BSR may trigger the transmission of an SR. If no uplink grant (grant) is obtained after the last SR transmission, SR retransmission may be triggered.

Four formats of BSR are specified in NR Rel-15, namely short BSR (Short BSR), short truncated BSR (Short Truncated BSR), long BSR (Long BSR), and Long truncated BSR (Long Truncated BSR). The Short BSR and Short Truncated BSR consist of 8 bits, of which 3 bits are used for the LCG ID,5 bits are used for the Buffer Size (Buffer Size), 5 bits provide 2^5 =32 indices from 0 to 31, 0 index represents 0byte BSR,31 index value represents 150000Bytes BSR, and 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 that have the same format but are variable in size. The first byte represents the LCG ID and the other parts represent the buffer status report. The Long BSR and Long Truncated BSR use 8 bits to allow 2^8 =256 indexes, which can accommodate the larger buffer status of 81338368 bytes.

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

Since the characteristic of 8 LCGs is introduced into NR, for short BSR or short truncated BSR, 3 bits are required to indicate LCG ID, and only 5 bits remain to indicate buffer data amount, so that only buffer area size corresponding to indexes 0-31 can be indicated, and quantization accuracy of buffer data amount is lower than that indicated by LTE using 6-bit or that indicated by long BSR or long truncated BSR using 8bit in NR.

3. BSR reporting for narrowband internet of things (Narrow Band Internet of Things, NB-IoT) terminals

NB-IoT terminals belong to LTE radio protocol based terminals supporting only one LCG (i.e., lcg#0), where the buffer size indication contains 6 bits, and similar to normal LTE terminals, the same quantization table containing 64 entries is used.

The BSR reporting method provided by the embodiment of the application can be applied to the scene that the A-IoT device executes the BSR reporting.

In the related art, when the a-IoT device is configured with one LCG, the format of the BSR used when applying for uplink resources to the network-side device may be a short BSR or a short truncated BSR. However, in the short BSR or the 1-byte payload of the short-cut BSR in NR, the LCG ID occupies 3 bits, so only 5 bits are left for buffering information reporting, resulting in waste of transmission resources.

According to the BSR reporting method provided by the embodiment of the application, the A-IoT device can determine whether to use the BSR format which does not contain the LCG identification or the BSR table with the buffer indication range smaller than the default table (namely, the quantization precision is larger than the default table) to execute the BSR reporting based on the device type, the LCG number or the configuration information of the A-IoT device. For example, if the a-IoT device configures only one LCG, the BSR reporting may be performed using the first BSR format, and since the BSR format used does not include the LCG identifier, the BSR identifier is prevented from being reported to the network device by occupying a bit load, so that transmission resources for performing the BSR reporting may be saved. For another example, when the device type of the a-IoT device is the a-IoT device, BSR reporting may be performed by using a BSR table with higher quantization accuracy, so the a-IoT device may report a buffer data amount indication closer to an actual buffer data amount according to the BSR table, so that the network device may allocate transmission resources actually required for the a-IoT device based on the buffer data amount indication reported by the a-IoT device, thereby being capable of saving transmission resources.

The BSR reporting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Fig. 2 is a flowchart of a BSR reporting method according to an embodiment of the present application, where the BSR reporting method shown in fig. 2 may include the following steps S201 and S202:

Step S201, the terminal equipment acquires first information.

In some embodiments, the first information includes at least one of:

The device type of the terminal device;

The number of logical channel groups LCGs of the terminal device;

And first configuration information for indicating whether the terminal device performs BSR reporting using the first BSR information.

By way of example, the device types may include a-IoT devices, read-write devices, and the like.

Illustratively, the number of LCGs may be 1. When the terminal equipment configures a single LCG, the number of LCGs of the terminal equipment is 1.

Illustratively, the first configuration information is configuration information provided by the first network device.

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.

In some embodiments, the terminal device is a User Equipment (UE), and the first network device is a base station.

Step S202, the terminal equipment determines whether to use the first BSR information to execute BSR reporting based on the first information.

The first BSR information includes at least one of a first BSR format and a first BSR table, the first BSR format does not include a logical channel group LCG identifier or the first BSR format includes only a buffer data amount indication of a single LCG, the first BSR table includes at least one buffer data amount, and a maximum buffer data amount of the first BSR table is smaller than a maximum buffer data amount of a default BSR table.

In some embodiments, the first BSR information is configured or preconfigured by the first network device, or the LCG number is configured, preconfigured, or pre-defined by a protocol by the first network device.

In some embodiments, the first BSR format is a format of a MAC CE that transmits a BSR, which may also be referred to as a BSR MAC CE format.

In some embodiments, the first BSR format described above is used for a terminal device configured with 1 LCG to send a BSR report, and only a single LCG's buffered data amount indication (i.e., buffer size indication) is included in the BSR report and no LCG ID indication is included. The buffer data amount indication may be referred to as buffer indication, for example, for indicating the buffer data amount of the LCG of the terminal device.

It will be appreciated that the amount of buffered data of the LCG of the terminal device is the amount of data in the LCG buffer of the terminal device.

In some embodiments, the first BSR format includes M Bit payloads including K buffered data amount indication Bit payloads and M-K Reserved Bit payloads (Reserved Bit) with 0< M≤8, 0< K≤M, and both M and K being positive integers.

It will be appreciated that the reserved bit payload described above is a reserved bit payload.

The first BSR format may include 8 bit payloads including 6 buffer indication bit payloads and 2 reserved bit payloads as shown in fig. 3A, or the first BSR format may include 8 bit payloads including 7 buffer indication bit payloads and 1 reserved bit payload, or the first BSR format may include 8 bit payloads all used for buffer indication as shown in fig. 3B.

It should be noted that, the bit load (i.e., bit) in the embodiment of the present application may also be referred to as a bit.

The first BSR format provided by the embodiment of the present application does not include an LCG ID field, and the short BSR or short-cut BSR relative to NR and the short BSR or short-cut BSR in LTE can lengthen the field length for indicating the buffered data amount, so that the buffered data amount indication field can reach 8 bits, thereby improving the buffered data amount indication precision.

In some embodiments, the first BSR table includes at least one buffered data amount. It will be appreciated that the at least one buffered data volume constitutes a buffered data volume range, which may also be referred to as a buffered indication range. In other words, the buffer indication range of the first BSR table may be a numerical range between a maximum buffer size (i.e., a maximum buffer data amount) and a minimum buffer size in the first BSR table. Illustratively, the buffer indication may range from 0 to 10000 bytes.

Similarly, the default BSR table includes at least one buffer data amount. It is understood that the at least one buffered data volume constitutes a buffered data volume range. In other words, the buffer data size range of the default BSR table may be a numerical range between the maximum buffer size (i.e., the maximum buffer data size) and the minimum buffer size in the default BSR table. Illustratively, the amount of buffered data may range from 0 to 150000 bytes.

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

The N Buffer data amounts may be Buffer Size (BS), for example. For example, the terminal device may query the BS corresponding to the buffered data amount of the LCG from the first BSR table.

For example, the buffer data amount of the terminal device is less than 5Bytes, BS in the corresponding first BSR table may be 0 to 5, expressed as 0< bs≤5, and the buffer data amount of the terminal device is greater than 110 Bytes and less than 120Bytes, BS in the corresponding first BSR table may be 110 to 120, expressed as 110< bs≤125.

In some embodiments, the first BSR table further includes X indexes corresponding to N buffered data amounts, where the maximum buffered data amount in the first BSR table is less than 150000 when the index range of the X indexes is 0 to 31, or is less than 81338368 bytes when the index range of the first BSR table is 0 to 255, and X is an integer greater than or equal to 0.

For example, the maximum buffer data amount in the first BSR table may be 5000 bytes, 10000 bytes, 15000 bytes, or the like.

For example, each index in the first BSR table corresponds to a buffer data amount range, and one buffer data amount range may include a plurality of buffer data amounts, and each index is used to indicate a buffer data amount range of the terminal device.

It should be noted that, the maximum data buffering amount and the buffered data amount corresponding to each index may be specifically set according to actual requirements, which is not limited in the embodiment of the present application.

Currently, the existing BSR table with common all traffic data amounts supports a larger buffer indication of the traffic data amount, and as the traffic data amount of the a-IoT terminal is generally smaller, the existing BSR table may not support BSR reporting of the a-IoT device, or even if the a-IoT device may use the existing BSR table to perform BSR reporting, the indicated buffer data amount may be far greater than the actual buffer data amount of the a-IoT device, thereby resulting in waste of transmission resources.

Compared with the maximum buffer data volume corresponding to the existing 8-bit BSR table, the first BSR table provided by the embodiment of the application can indicate smaller maximum buffer data volume, so that the buffer data volume range corresponding to the BSR table is more matched with the service data buffer data volume of the A-IoT device, the quantization accuracy of buffer report is higher, and the indicated buffer data volume can be more similar to the actual data volume of the A-IoT device, thereby saving transmission resources.

In some embodiments, the terminal device has a first capability, where the first capability is a capability of BSR reporting using a first BSR format.

Illustratively, the protocol may predefine that an interrupt device configuring a single LCG is capable of BSR reporting using a new BSR MAC CE.

The BSR reporting method comprises the steps that a terminal device obtains first information, whether to use first BSR information to execute BSR reporting is determined based on the first information, wherein the first BSR information comprises at least one of a first BSR format and a first BSR table, the first BSR format does not comprise a logic channel group LCG identifier or only comprises a buffer data amount indication of a single LCG, the first BSR table comprises at least one buffer data amount, the maximum buffer data amount of the first BSR table is smaller than the maximum buffer data amount of a default BSR table, the first information comprises at least one of equipment type of the terminal device, the logic channel group LCG number of the terminal device and first configuration information, and the first configuration information is used for indicating whether the terminal device uses the first BSR information to execute BSR reporting. According to the method, the terminal equipment can determine whether to use the BSR format which does not contain LCG identification or the BSR table with the buffer indication range smaller than the default table (namely, the quantization precision is larger than the default table) to execute BSR report based on the equipment type, the LCG quantity or the configuration information of the terminal equipment, and the BSR format used for executing the BSR report can not contain LCG identification, so that the occupied bit load is avoided to report the BSR identification to the network equipment, and transmission resources for executing the BSR report can be saved, and the terminal equipment can use the BSR table with the higher quantization precision to execute the BSR report, so that the terminal equipment can report the buffer indication which is closer to the actual buffer data quantity according to the BSR table, and the transmission resources can be saved.

In some embodiments, the first information includes a device type of the terminal device, and the step S202 may include the following step S202a:

Step S202a, in the case that the device type is the a-IoT device type, the terminal device performs BSR reporting using the first BSR information.

In some embodiments, the terminal device performs BSR reporting using the first BSR information in case it determines that the device type is the first device type.

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

For example, for a terminal device of a first device type, the protocol may predefined that the terminal device of the first device type supports only one LCG, and after the terminal device of the first device type accesses the base station, the terminal device may perform BSR reporting using the first BSR information.

For example, 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.

In the embodiment of the application, the A-IoT device can use the first BSR format to execute the BSR report, and the first BSR format does not comprise the LCG ID field, so that the A-IoT device can use the maximum of 8 bit loads to perform the buffer data quantity indication, thereby improving the buffer indication precision, or the A-IoT device can use the first BSR table to execute the BSR report, so that the range of the buffer data quantity corresponding to the BSR table is more matched with the service data buffer data quantity of the A-IoT device, the quantization precision of the buffer report is higher, and the indicated buffer data quantity size can be more similar to the actual data quantity size of the A-IoT device, thereby saving transmission resources.

In some embodiments, the first information includes the number of logical channel group LCGs of the terminal device, and the process of step S202 may include the following step S202b:

step S202b, in the case that the terminal device is configured with a single LCG, the terminal device performs BSR reporting using the first BSR information.

In some embodiments, the terminal device performs BSR reporting using the first BSR information when determining that the number of LCGs is one.

Illustratively, taking the terminal device as an a-IoT device, the a-IoT device may perform BSR reporting using the first BSR information in the case of configuring one LCG.

In some embodiments, an embodiment of the present application provides an LCG configuration method, where the LCG configuration method may include the following step S203:

Step S203, the terminal device receives the second configuration information from the first network device.

Wherein, the second configuration information is used for configuring a single LCG.

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

For example, the base station may send configuration information (i.e., second configuration information) to the a-IoT device to configure a single LCG for the a-IoT device.

In the embodiment of the 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, and the A-IoT device can use the first BSR format which does not contain an LCG ID field to report when the A-IoT device is configured with only one LCG and the A-IoT device executes BSR report, thereby indicating the cache data quantity by using more bit loads and improving the indication precision.

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

In some embodiments, an embodiment of the present application provides a capability reporting method, where the capability reporting method may include the following step S204:

And step S204, the terminal equipment sends the first capability information to the first network equipment.

The first capability information is used for indicating that the terminal equipment has a first capability, and the first capability is a capability of performing BSR reporting by using a first BSR format.

For example, taking a terminal device as an a-IoT device, the a-IoT device may report first capability information to a base station, and the base station may instruct the a-IoT device to perform BSR reporting using a first BSR format according to the first capability information.

In the embodiment of the application, the terminal equipment can report the capability of executing the BSR report by using the first BSR format to the base station, and the base station can instruct the terminal equipment to execute the BSR report by using the first BSR format under the condition that the terminal equipment has the capability, so that the network equipment is prevented from carrying out invalid indication under the condition that the terminal equipment does not have the corresponding capability, and the wireless resource is saved.

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

In some embodiments, the BSR reporting method provided by the embodiment of the present application may include the following steps S205 to S207:

Step S205, the terminal equipment determines a first index corresponding to the cache data amount of the LCG based on the second BSR table.

The second BSR table is a first BSR table or a default BSR table.

Step S206, the terminal equipment uses the first BSR format to send a first BSR report to the first network equipment.

The first BSR report carries a first index, where the first index is used to indicate a cache data size of the LCG.

Step S207, the first network device receives a first BSR report from the terminal device.

For example, after receiving the first BSR report, the first network device determines the buffer information of the terminal device according to the first BSR report.

For example, the first BSR report may be a first BSR MAC CE.

In some examples, in a case where a single LCG is configured, when performing BSR reporting, the terminal device may determine a buffer data amount (BS) that matches the buffer data amount of the single LCG from the first BSR table or the default BSR table, and send, using the first BSR format, the BSR reporting carrying an index corresponding to the matched buffer data amount (i.e., the first index). Illustratively, the index may occupy at most 8 bit payloads of the BSR MAC CE.

For example, taking a terminal device as an a-IoT device, in a case that the a-IoT device configures a single LCG, the a-IoT device may determine, from a first BSR table, a buffered data amount that matches the buffered data amount of the single LCG, and send an index corresponding to the matched buffered data amount through a second BSR report using the first BSR format. Illustratively, the index may occupy 8 bit loads of the second BSR report.

By way of example, in combination with the above embodiment, taking the terminal device as an example, in the case that the UE configures a single LCG, the UE may determine the buffered data amount matched with the buffered data amount from the default BSR table, and send the index corresponding to the buffered data amount through the second BSR report by using the first BSR format.

In other examples, when receiving an indication to perform BSR reporting using the first BSR format (i.e., the first configuration information), the terminal device determines a buffered data volume (BS) that matches a buffered data volume from the first BSR table or the default BSR table when performing BSR reporting, and sends the BSR reporting carrying an index corresponding to the buffered data volume using the first BSR format.

For example, taking a terminal device as an a-IoT device, when the a-IoT device receives an indication of performing BSR reporting using a first BSR format, the a-IoT device may determine a buffered data amount matching the buffered data amount from the first BSR table, and send an index corresponding to the buffered data amount through a second BSR report using the first BSR format.

In the embodiment of the application, the terminal equipment can determine the buffer data quantity indication (namely the first index) based on the first BSR table or the default BSR table, and send the BSR report carrying the index corresponding to the buffer data quantity by using the first BSR format, and the terminal equipment can send the buffer data quantity indication by using 8 bits at most because the first BSR format does not comprise the LCG ID field, so that the indicated buffer data quantity size can be more approximate to the actual data quantity size of the terminal equipment, thereby improving the indication precision.

In some embodiments, the BSR reporting method provided by the embodiment of the present application may include the following steps S208 and S210:

step S208, the terminal equipment determines a second index corresponding to the cache data amount of the LCG based on the first BSR table.

Step S209, the terminal equipment sends a second BSR report to the first network equipment.

Step S210, the first network device receives a second BSR report from the terminal device.

The second BSR report carries a second index, where the second index is used to indicate the buffer data size of the LCG.

In some examples, when the terminal device configures a single LCG, it may determine, when performing BSR reporting, a buffered data amount that matches the buffered data amount from the first BSR table, and send an index (i.e., a second index) corresponding to the buffered data amount through the second BSR reporting.

Taking a terminal device as an example, in the case that the a-IoT device configures a single LCG, the a-IoT device may determine, from a first BSR table, a buffered data amount that matches the buffered data amount, and send an index corresponding to the buffered data amount through a second BSR report.

By way of example, in combination with the above embodiment, taking the terminal device as an example, in the case that the UE configures a single LCG, the UE may determine, from the first BSR table, the buffered data amount that matches the buffered data amount, and send an index corresponding to the buffered data amount through the second BSR report.

In other examples, when receiving an instruction (i.e., first configuration information) that the BSR report is performed using the first BSR table, the terminal device determines, when the BSR report is performed, a buffered data amount matching the buffered data amount from the first BSR table, and sends an index corresponding to the buffered data amount through the second BSR report.

For example, taking a terminal device as an a-IoT device, when the a-IoT device receives an indication of performing BSR reporting using a first BSR table, the a-IoT device may determine a buffered data amount matching the buffered data amount from the first BSR table, and send an index corresponding to the buffered data amount through a second BSR report.

In the embodiment of the application, the terminal device can determine the buffer data amount indication (namely the second index) based on the first BSR table, and the buffer indication range of the first BSR table is smaller than the buffer indication range of the default table, so that the buffer data amount range corresponding to the BSR table is more matched with the service data buffer data amount of the terminal device (such as an A-IoT device) with smaller service data amount, the quantization precision of buffer report is higher, and the indicated buffer data amount can be more approximate to the actual data amount of the terminal device, thereby saving transmission resources.

In the embodiment of the application, the terminal equipment can use the BSR format which does not contain LCG identification or the BSR table with the buffer indication range smaller than the default table (namely, the quantization precision is larger than the default table) to execute BSR report, and the BSR format used for executing BSR report does not contain LCG identification, so that the occupation of bit load is avoided to report the BSR identification to the network equipment, thereby saving transmission resources for executing BSR report, or the terminal equipment can use the first BSR table to execute BSR report, and the terminal equipment can report buffer indication which is closer to the actual buffer data quantity according to the BSR table because the quantization precision of the first BSR table is higher, thereby saving transmission resources.
