Description

UE reports BSR and base station to determine the method for the buffer data size that UE reports

Technical field

The present invention relates to wireless communication technology field, relate in particular to a kind of UE and report BSR and base station to determine the method for the buffer data size that UE reports, reach UE and base station.

Background technology

The peak rate that LTE-A (LTE Advanced) system supports is greatly improved than LTE (Long Term Evolution, Long Term Evolution) system, requires to reach descending 1Gbps, up 500Mbps.Simultaneously, LTE-A system requirements and LTE system are compatible well, the maximum bandwidth 20MHz of LTE system.

Based on improve peak rate, with the LTE system compatible with make full use of the needs of frequency resource, the LTE-A system has introduced carrier aggregation (Carrier Aggregation, CA) technology.

Carrier aggregation technology is meant that up-downgoing respectively comprises a plurality of member carriers (CC, Component Carrier) in a sub-district, rather than LTE and before have only the pattern of a cover carrier wave in the wireless communication system.Evolution base station eNB is to unified management of the member carrier of the many covers in the sub-district and scheduling.Member carrier can be continuous or discrete, for the LTE compatibility, the maximum bandwidth of each member carrier is 20MHz.

LTE and LTE-A system all are based on the system of scheduling, are the required running time-frequency resource of UE (User Equipment, user terminal) distribute data transmission by the base station, and terminal is carried out downlink data reception or upstream data transmission according to the dispatching command of base station.

Transmitting uplink data is by base station scheduling, and base station dispatcher is determined can permit UL grant notice terminal by uplink scheduling after the ascending resource distribution condition.It is data volume in the terminal buffers that base station dispatcher carries out one of foundation that ascending resource distributes.The base station wants to know this information, just need terminal to the base station carry out reporting cached state (Buffer Status Report, BSR).

Because the raising of peak rate, the BSR mechanism of LTE system can not satisfy the demand of LTE-A system.BSR mechanism is as follows among the LTE Rel-8 at present:

The ★ BSR rrc layer parameter configuration of being correlated with

RRC in the LTE system (Radio Resource Control, Radio Resource control) layer comprises following two timers at the parameter of BSR configuration: forbid the timer retxBSR-Timer that BSR reports; The timer periodicBSR-Timer that periodicity BSR reports.

In the LTE system, have only a uplink member carrier, BSR is a process at UE, so the above-mentioned timer of rrc layer configuration is based on the UE configuration.

★ BSR classification and trigger mechanism are as follows:

1) conventional BSR (Regular BSR): triggering when having data to arrive than the data arrival of the data higher priority in the current cache or in originally for empty buffer memory; Trigger when forbidding in timer expiry that BSR reports and the buffer memory data being arranged.

2) periodicity BSR (Periodic BSR): the timer expiry that periodicity BSR reports, then triggering periodically, BSR reports.

3) BSR (Padding BSR) incidentally: if UE is organizing MAC (Medium Access Control, the medium access control) PDU (Protocol Date Unit, protocol Data Unit) time, also have resource to use except the data of needs transmission, can triggering incidentally, BSR reports.

★ BSR reports mechanism

1) BSR reports form

BSR is with media access control layer control unit (MAC Control Element, MAC CE,) form report, be divided into MAC head and MAC CE two parts when reporting, MAC CE partly is also referred to as the load part, and the MAC CE of BSR partly comprises long BSR (long BSR) and short BSR (short BSR)/two kinds of forms of brachymemma BSR (truncated BSR), is the form of MAC head as Fig. 1, Fig. 2 is the MAC CE form of long BSR for the MAC CE form of weak point/brachymemma BSR as 3.

The implication in each territory is as follows among the MAC head of BSR and the MAC CE:

R: reserved bit;

E: extended bit, being used to indicate next byte is MAC head or load part;

LCID (Logical Channel ID, logical channel number): be used to identify the logical channel number of corresponding load part, long BSR, lack BSR, brachymemma BSR and incidentally BSR a LCID is respectively arranged, as shown in the table:

The LCID of table 1UL-SCH (Uplink Shared Channel, Uplink Shared Channel)

Index	LCID?values
		00000	Common Control Channel CCCH
00001-01010	The sign of logic channel
		01011-11001	Reserve
11010	Power headroom reporting
		11011	C-RNTI
11100	Brachymemma BSR
		11101	Short BSR
11110	Long BSR
		11111	BSR incidentally

LCG ID (Logical Channel Group ID, logic channel group #): give the correct time on the BSR in the LTE system and divided 4 logic channel groups.

Buffer Size: the metadata cache amount in the counterlogic channel group.Buffer Size represents with 6bit in the LTE system, represents 64 quantification gradations (with 0 to 63 expression) of buffer area data volume, the BSR table that each quantification gradation corresponding cache district data volume ginseng is shown in Table 2.

2) the MAC CE type selecting mechanism of BSR

For conventional BSR and BSR periodically, if more than a LCG have data to report and resource enough, then report long BSR, otherwise report short BSR; For BSR incidentally, if the available resources bit number more than or equal to (the MAC CE+MAC head of short BSR) but less than (MACCE+MAC of long BSR), if then UE has more than a LCG and has data to report, then reports brachymemma BSR, otherwise reports short BSR; If the available resources bit number then reports long BSR more than or equal to (the MAC CE+MAC head of long BSR).

3) BSR reports rule

After triggering BSR, but periodically BSR and incidentally BSR all to have the ascending resource time spent just can report, but conventional BSR is not having the ascending resource time spent then can trigger SR (Scheduling Request, dispatch request) process, asks the base station to distribute ascending resource to UE.

BSR if this ascending resource has just enough sent all upstream datas, then can not sent out after distributing ascending resource to UE in the base station, directly sends upstream data; If this resource sends all upstream datas inadequately, preferentially report conventional BSR or periodicity BSR.

A MAC PDU comprises a BSR at most.BSR priority is: conventional BSR=is the BSR of BSR＞incidentally periodically, if a plurality of BSR trigger simultaneously, only report priority the highest, report content identical with periodicity BSR owing to it for conventional BSR, all comprise whole available data amount informations in the terminal buffers, report form identical, individual the reporting of optional one gets final product.The MAC layer is preferential this two class MAC CE that places when organizing MAC PDU, just places MAC SDU (Serving Date Unit, service data unit) thereafter.

Incidentally the priority of BSR is lower than data.

5) processing after BSR reports

As long as BSR is triggered and can reports, then start/restart the timer that BSR periodically reports and forbid the timer that BSR reports, but should be noted that for brachymemma BSR, can not start/restart the timer that periodicity BSR reports, only start/restart the timer of forbidding that BSR reports.

The buffer data size of terminal is that Buffer Size maximum occurrences is 150Kbyte in the LTE system, and the Buffer Size maximum occurrences of terminal determines that as yet two kinds of tendency: 1500Kbyte or 1200Kbyte are arranged at present in the LTE-A system of introducing CA technology.

This shows that no matter the maximum Buffer Size of terminal according to which kind of mode obtains in the LTE-A system of introducing CA technology, the maximum Buffer Size of terminal obviously is far longer than the maximum Buffer Size of LTE system terminal in the LTE-A system of introducing CA technology.

Therefore the BSR table of LTE system is not enough, and in order to address this problem, at present a kind of method of relatively generally acknowledging is exactly to introduce one or more BSR table again on the basis that keeps LTE Rel-8BSR table.But determine also at present how to carry out under a plurality of BSR table that BSR table selects and BSR reports.

Embodiment

Report BSR and base station to determine the method for the buffer data size that UE reports, reach UE and base station below in conjunction with drawings and Examples to UE provided by the invention, illustrate in greater detail.

In the LTE-A system,, introduced the CA technology in order to support higher peak rate.Because the raising of peak rate, the BSR of LTE system reports mechanism can not satisfy the demand of multicarrier system, has therefore introduced a plurality of BSR forms at multicarrier system, claims that below the BSR form is BSR table.

Present most of company all tends to introduce a plurality of BSR table at multicarrier system, but do not determine that also how carrying out BSR under a plurality of BSR table reports, the present invention has provided a kind of UE and has reported BSR and base station to determine the method for the buffer data size that UE reports, reaches UE and base station, in the BSR report method based on a plurality of BSR table, BSR of qualification UE reports and can only select a BSR table, can not select different BSR table based on LCG.Can solve is having under a plurality of BSR form situations how to carry out the problem that the BSR form selects to report BSR.

As shown in Figure 4, UE provided by the present invention reports the method for BSR to comprise step:

Step S401 when determining to satisfy BSR and reporting trigger condition, selects a BSR form according to setting rule from least two different B SR forms, wherein store in each BSR form and different number range corresponding quantitative values;

As previously mentioned, the quantized value of storing among the BSR table (being quantification gradation) is corresponding with different number ranges, therefore the data volume in the buffer area can be mapped as different quantification gradations.

Buffer Size maximum occurrences is 150Kbyte in the LTE system, and the maximum Buffer Size of the LTE system that is far longer than of the BufferSize of LTE-A system maximum, be about 8 or 10 times of LTE system, therefore the BSR table of LTE system can not satisfy the demand of LTE-A system, and a kind of solution is exactly newly to introduce one or more BSR table on the basis of the BSR table of LTE system.The BS table of LTE-A system is divided into two classes on the whole like this, and a class satisfies the quantification requirement of terminal buffers data volume in the LTE system, the another kind of quantification requirement of satisfying terminal buffers data volume in the LTE-A system.Here do not pay close attention to as at least two concrete quantification manners of BSRtable.

UE will select a BSR table according to setting rule when the present invention is triggered according to each BSR from least two different B SR forms, selected BSR table wants to satisfy the quantification gradation requirement of current terminal Buffer Size, and does not allow Different L CG to select different BSR table;

Step S402, the number range corresponding quantitative value in selected BSR form under the buffer data size of determining to report;

Behind the buffer data size of promptly determining to report, in the BSR table that selects, search number range corresponding quantitative value under it.

Step S403 utilizes the quantized value of determining, BSR is offered the base station with media access control layer control unit MACCE in form.

Promptly can determine corresponding bit information, thereby the value of buffer size among the BSR of definite MAC CE form carries out reporting BSR after out of Memory is filled according to definite quantized value.

The data cached metering method that UE reports is determined in base station provided by the invention, described base station stored has at least two different B SR forms, store in each BSR form and different number range corresponding quantitative values, be base station side with the BSR table of end side institute reference be identical, as shown in Figure 5, comprising:

Step S501 receives the BSR of the MAC CE form that UE sends, according to setting rule determines that UE selects when sending described BSR BSR form;

Step S502 obtains the quantized value among the described BSR, and according to described quantized value value corresponding scope in the BSR form that described UE selects, determines the buffer data size that described UE reports.

End side is only selected a BSR table according to setting rule, and the same rule of base station side foundation is determined the BSR table of end side, and a BSR transmission only need be searched the buffer data size of quantized value reflection among the Buffer size in a BSR table.

End side among the present invention, all utilize in existing at least two different B SR forms, one class satisfies the quantification requirement of terminal buffers data volume in the LTE system, the characteristics that the quantification of terminal buffers data volume requires in the another kind of LTE-A of the satisfying system, come to determine select a BSR table, make that data volume can reasonably be quantized in the current terminal buffers.

Therefore, a kind of concrete mode of above-mentioned setting rule is to determine that UE communicates by letter in LTE system communication mode or communicates by letter in LTE-A system communication mode based on the configuration information of UE, when determining that UE communicates by letter in LTE system communication mode, select to satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires; When determining that UE communicates by letter in LTE-A system communication mode, select a BSR table of the quantification requirement of terminal buffers data volume in the LTE-A system.Thereby the BSR table that makes selection wants to satisfy the quantification gradation requirement of current terminal Buffer Size.The another kind of concrete mode of above-mentioned setting rule is to select to satisfy the BSR table that the quantification gradation of current terminal Buffer Size requires by the buffer data size relevant information that UE reports.

When adopting first mode, because base station side and end side be the configuration information of total UE all, therefore base station and UE pre-configured overlaps unified BSR table selection mode, and then UE can select BSR table by the implicit expression mode, does not promptly need the BSR table of its selection of end side informing base station side; When adopting the second way, because base station side itself and do not know terminal buffers data volume relevant information, so UE can select BSR table by display mode, promptly needs end side to need the BSR table of its selection of informing base station side.

When UE selected BSR table by the implicit expression mode in the embodiment of the invention, UE selected a BSR form according to setting rule among the step S401, and step S501, and following several mode specifically can be adopted according to setting the BSR form that rule determines that UE selects in the base station:

1) end side is selected BSR table based on the UE version, and base station side is determined the BSR table that UE selects based on the UE version

The different editions with UE is corresponding respectively at least two different B SR forms of end side and base station side, end side is determined the version of described UE based on the configuration information of UE, selects a BSR form corresponding with the version of determined UE from least two different B SR forms.Base station side is determined the version of described UE based on the configuration information of UE, determines the BSR form corresponding with the version of determined UE, is the BSR form of described UE selection.

Because UE adopts different editions in LTE system and the LTE-A system, actual in the present embodiment is to determine that according to the version of UE UE communicates by letter in LTE system communication mode or in LTE-A system communication mode.

Particularly, it is corresponding with the version of UE in the LTE system to satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires, and it is corresponding with the version of UE in the LTE-A system to satisfy the BSRtable that the quantification of terminal buffers data volume in the LTE-A system requires.

For example, there are 2 as the BSR form, it is that the BSR table of Rel-8/9 compatibility is called table0 that the quantification of satisfying terminal buffers data volume in the LTE system requires, satisfy the BSR table that the quantification of terminal buffers data volume in the LTE-A system requires and be called tablel, wherein table0 is corresponding with the version Rel-8/9 of UE, and another table1 is corresponding with the version Rel-10 of UE.

If then determine that according to the configuration information of UE the version of UE is Rel-8/9, then give the correct time on the BSR and select table0, if determine that the version of UE is Rel-10UE, then give the correct time on the BSR and select table1.Equally, base station side is determined the version of UE according to the configuration of UE, and that determine its selection according to the version of this UE is table0 or table1.

2) end side is selected BSR table based on the ability rating (UE-category grade) of UE, and base station side is determined the BSR table that UE selects based on the UE-category grade of UE

The different ability ratings with UE are corresponding respectively at least two different B SR forms of base station side and end side, end side is determined the ability rating of described UE based on the configuration information of UE, selects a BSR form corresponding with the ability rating of determined UE from least two different B SR forms.

Base station side is determined the ability rating of described UE based on the configuration information of UE, determines the BSR form corresponding with the ability rating of determined UE, is the BSR form of described UE selection.

Because the LTE system is different with the UE-category grade of UE in the LTE-A system, actual in the present embodiment is to determine that according to the UE-category grade of UE UE communicates by letter in LTE system communication mode or in LTE-A system communication mode.

Particularly, it is corresponding with the ability rating of UE in the LTE system to satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires, and it is corresponding with the ability rating of UE in the LTE-A system to satisfy the BSR table that the quantification of terminal buffers data volume in the LTE-A system requires.

For example, the BSR form has 2, satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires and be called table0, satisfy the BSRtable that the quantification of terminal buffers data volume in the LTE-A system requires and be called table1, wherein table0 is corresponding with one or more UE-category grade that is lower than the setting ability rating of UE, and another table1 is corresponding with the UE-category grade that is lower than setting UE-category of UE.

If then determine that according to the configuration information of UE the UE-category grade of UE is lower than setting UE-category grade, then give the correct time on the BSR and select table0, be not less than setting UE-category grade if determine the UE-category of UE, then give the correct time on the BSR and select table1.Equally, base station side is determined the UE-category grade of UE according to the configuration information of UE, and that determine its selection by same rule according to the UE-category grade of this UE is table0 or table1.

3) end side is the member carrier CC number/CC bandwidth/up input and output mode selection BSR table of UE configuration based on the base station, and base station side is based upon the CC number/CC bandwidth/up input and output mode of UE configuration and determines the BSR table that UE selects

The ★ end side is the CC number selection BSR table of UE configuration based on the base station, and base station side is based upon the CC number of UE configuration and determines the BSR table that UE selects

At least two different B SR forms of base station side and end side are that the CC number of UE configuration is corresponding with the base station respectively, end side determines that the base station is the CC number of described UE configuration, from at least two different B SR forms, selecting with determined base station is a corresponding BSR form of CC number of UE configuration; Base station side is defined as the CC number of described UE configuration, determines and the corresponding BSR form of CC number of being defined as UE configuration, is the BSR form of described UE selection.

Because the base station is that the CC number of UE configuration is different in LTE system and the LTE-A system, as base station in the LTE system is CC of UE configuration, and actual in the present embodiment is to be that the CC number of UE configuration determines that UE communicates by letter in LTE system communication mode or in LTE-A system communication mode according to the base station.

Particularly, the CC number that satisfies base station in BSR table that the quantification of terminal buffers data volume in the LTE system requires and the LTE system and be the UE configuration is corresponding, and it is corresponding to satisfy base station in BSR table that the quantification of terminal buffers data volume in the LTE-A system requires and the LTE-A system and be the CC number that UE disposes.

For example, the BSR form has 2, satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires and be called table0, satisfy the BSRtable that the quantification of terminal buffers data volume in the LTE-A system requires and be called table1, wherein table0 and base station are that CC of UE configuration is corresponding, and it is corresponding that another table1 and base station are that UE disposes a plurality of CC.

If when then determining that according to the configuration information of UE the base station is CC of UE configuration, then give the correct time on the BSR and select table0, be UE when disposing a plurality of CC if determine the base station, then give the correct time on the BSR and select table1.Equally, base station side is according to according to the CC number for UE configuration, and that determine the UE selection by same rule is table0 or table1.

The ★ end side is the CC bandwidth selection BSR table of UE configuration based on the base station, and base station side is based upon the CC bandwidth of UE configuration and determines the BSR table that UE selects

At least two different B SR forms of base station side and end side are that the CC bandwidth of UE configuration is corresponding with the base station respectively, end side determines that the base station is the CC bandwidth of UE configuration, from at least two different B SR forms, selecting with determined base station is a corresponding BSR form of CC bandwidth of UE configuration.Base station side determines that the base station is the CC bandwidth of UE configuration, determines and the determined corresponding BSR form of CC bandwidth for the UE configuration, is the BSR form of described UE selection.

Because the base station is that the CC bandwidth of UE configuration is different in LTE system and the LTE-A system, as base station in the LTE system is that UE configuration CC bandwidth is 20MHz to the maximum, and actual in the present embodiment is to be that the CC bandwidth of UE configuration determines that UE communicates by letter in LTE system communication mode or in LTE-A system communication mode according to the base station.

Particularly, the CC bandwidth that satisfies base station in BSRtable that the quantification of terminal buffers data volume in the LTE system requires and the LTE system and be the UE configuration is corresponding, and it is corresponding to satisfy base station in BSR table that the quantification of terminal buffers data volume in the LTE-A system requires and the LTE-A system and be the CC bandwidth that UE disposes.

For example, the BSR form has 2, satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires and be called table0, satisfy the BSRtable that the quantification of terminal buffers data volume in the LTE-A system requires and be called table1, wherein table0 and base station are that the UE configuration is corresponding less than 20MHz CC bandwidth, and another table1 and base station are that UE disposes that to be not less than 20MHz CC bandwidth corresponding.

If then determine that according to the configuration information of UE the base station is the CC bandwidth of UE during less than 20MHz, then give the correct time on the BSR and select table0, be that UE configuration CC bandwidth is not less than 20MHz if determine the base station, then give the correct time on the BSR and select table1.Equally, base station side is according to according to the CC bandwidth for UE configuration, and that determine the UE selection by same rule is table0 or table1.

The ★ end side is the up input and output mode selection BSR table of UE configuration based on the base station, and base station side is based upon the up input and output mode of UE configuration and determines the BSR table that UE selects

At least two different B SR forms of base station side and end side are that the up input and output mode of UE configuration is corresponding with the base station respectively, end side determines that the base station is the input and output mode of UE configuration, from at least two different B SR forms, select with definite base station be the corresponding BSR form of input and output mode that UE disposes.Base station side determines that the base station is the input and output mode of UE configuration, determines and the determined corresponding BSR form of input and output mode for the UE configuration, is the BSR form of described UE selection.

Because the base station is that the up input and output mode of UE configuration is different in LTE system and the LTE-A system, as base station in the LTE system is that UE collocating uplink input and output mode is single input and output mode, and actual in the present embodiment is to be that the up input and output mode of UE configuration determines that UE communicates by letter in LTE system communication mode or in LTE-A system communication mode according to the base station.

Particularly, the single output mode of up single input that satisfies base station in BSR table that the quantification of terminal buffers data volume in the LTE system requires and the LTE system and be the UE configuration is corresponding, satisfy that the base station is up multiple-input and multiple-output (Uplink Multiple Input Multiple Output, UL MIMO) the pattern correspondence of UE configuration in BSR table that the quantification of terminal buffers data volume in the LTE-A system requires and the LTE-A system.

For example, the BSR form has 2, satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires and be called table0, satisfy the BSRtable that the quantification of terminal buffers data volume in the LTE-A system requires and be called table1, wherein to be that UE collocating uplink list is imported single output mode corresponding table0 and base station, and another table1 is that UE configuration UL MIMO pattern is corresponding with the base station.

If then determine that according to the configuration information of UE the base station is a UE collocating uplink list when importing single output mode, then give the correct time on the BSR and select table0, be UE configuration UL MIMO pattern if determine the base station, then give the correct time on the BSR and select table1.Equally, base station side is according to according to be UE collocating uplink input and output mode, and that determine the UE selection by same rule is table0 or table1.

4) end side is member carrier CC number/CC bandwidth selection BSR table of UE configuration and activation based on the base station, and base station side is based upon the CC number/CC bandwidth of UE configuration and determines the BSR table that UE selects

During concrete enforcement with above-mentioned 3) basic identical, different will determine that UE still is member carrier CC number/CC bandwidth/up input and output mode that the judgment basis of communicating by letter in LTE-A system communication mode is revised as activation with the LTE system.

The CC number that satisfies base station in BSR table that the quantification of terminal buffers data volume in the LTE system requires and the LTE system and be the UE configuration and activate is corresponding, and the CC number that satisfies base station in BSR table that the quantification of terminal buffers data volume in the LTE-A system requires and the LTE-A system and be UE configuration and activation is corresponding.

For example, if when determining that according to the configuration information of UE the base station is the CC of an activation of UE configuration, then giving the correct time on the BSR and select table0, is UE when disposing the CC of a plurality of activation if determine the base station, then gives the correct time on the BSR and selects table1.Equally, base station side is according to according to being UE configuration and the CC number that activates, and that determine the UE selection by same rule is table0 or table1.

The CC bandwidth that satisfies base station in BSR table that the quantification of terminal buffers data volume in the LTE system requires and the LTE system and be the UE configuration and activate is corresponding, and the CC bandwidth that satisfies base station in BSR table that the quantification of terminal buffers data volume in the LTE-A system requires and the LTE-A system and be UE configuration and activation is corresponding.

For example, if determine that according to the configuration information of UE the base station is the CC bandwidth of activation of UE during less than 20MHz, then giving the correct time on the BSR and select table0, is that the CC bandwidth of UE allocation activation is not less than 20MHz if determine the base station, then gives the correct time on the BSR and selects table1.Equally, base station side is according to according to being UE configuration and the CC bandwidth that activates, and that determine the UE selection by same rule is table0 or table1.

Detailed process and principle analysis are the same, no longer describe in detail here.

When UE selects BSR table by display mode in the embodiment of the invention, select BSR table according to setting rule, be specially the buffer data size relevant information that reports by UE, determine that UE communicates by letter in LTE system communication mode or communicates by letter in LTE-A system communication mode, when determining that UE communicates by letter in LTE system communication mode, select to satisfy the BSR table that the quantification of terminal buffers data volume in the LTE system requires; When determining that UE communicates by letter in LTE-A system communication mode, select to satisfy the BSR table that the quantification of terminal buffers data volume in the LTE-A system requires.The principle of being followed is that the largest buffered amount that can represent of the BSR table that selects is greater than the buffer data size that will report.

Owing to need indicate the selected BSR table of base station side, therefore, when in step S403, BSR being offered the base station with MAC CE in form, indicate selected BSR form by the described BSR that reports by end side.Among the step S501, the base station determines that according to setting rule the BSR table of UE selection is specially according to this indication definite.

Above-mentioned definite buffer data size relevant information can be determined according to the BSR type that specifically reports.

When determining in the present embodiment that the BSR type that will report is weak point/brachymemma BSR, above-mentioned buffer data size relevant information is specially the buffer data size in the logic channel group that will report, end side is selected a BSR form according to the buffer data size in the logic channel group that will report among the step S401 from least two different B SR forms.

When determining the BSR type that will report for long BSR, BSR table selection can be adopted one of following several modes:

According to the buffer data size in the maximum logic channel group of data volume, from least two different B SR forms, select a BSR form;

Buffer data size in the logic channel group that foundation triggering BSR reports is selected a BSR form from least two different B SR forms; As when having data to arrive than the data arrival of the data higher priority in the current LCG buffer memory or in originally for empty LCG buffer memory, this LCG triggering BSR reports.

Buffer data size in the highest logic channel group of priority is selected a BSR form from least two different B SR forms.

As shown in Figure 3, comprise buffer data size among a plurality of LCG among the long BSR, determine to select BSR table with reference to buffer data size among that LCG by above-mentioned a kind of mode.

Because the determined greatest measure difference of quantized value value corresponding scope at least two different B SR forms, as the determined greatest measure of BSR table that the quantification of satisfying terminal buffers data volume in the LTE system requires is 150kbyte, is 1200kbyte or 1500kbyte and satisfy the determined greatest measure of BSRtable that the quantification of terminal buffers data volume in the LTE-A system requires.When communicating by letter in LTE system communication mode, UE when communicating by letter, has very big difference on the largest buffered data volume that reports in LTE-A system communication mode.Particularly, UE selects the mode of BSR table to be in the present embodiment: the greatest measure that quantized value value corresponding scope in the buffer data size of foundation and the different B SR form is determined compares, and the selection greatest measure is greater than the BSR form of the buffer data size of institute's foundation.

As previously mentioned, when selecting BSR table for display mode, which BSR table that terminal need be indicated its selection to the base station by the BSR that reports is.Terminal has following three kinds to the method for the explicit indication in base station BSRTable in the present embodiment:

1) by the LCID territory in the MAC head among the BSR of MAC CE form, the BSRtable that indication is selected

End side: by the BSR table of the LCID territory value indication selection in the MAC head among the BSR of MAC CE form;

Base station side: determine the BSR table that UE selects according to the LCID territory value in the MAC head among the BSR of MAC CE form.

The LCID number of LTE system reservation at present is 17, from 01011 to 11001, suppose to use two BSR table for the CA system, and then need on the LCID basis of short/long/truncated/padding BSR correspondence, increase a LCID more separately.With two BSR table is example, and a kind of possible LCID that utilizes represents that the method for BSRtable index is as shown in table 3:

Table 3 utilizes LCID to represent BSR table index

Annotate: 10,110,/10,111,/11,000,/11,001 4 LCID are 4 LCID that LTE reserves.This method only is suitable for BSR table smaller or equal to 5 situation, otherwise the LCID that reserves needs expansion LCID number with not enough.

2) by the reserved bit position R bit in the MAC head among the BSR of MAC CE form, indicate selected BSR form

End side: utilize that the R bit in the MAC head distinguishes different BSR table among the BSR of MAC CE form;

Base station side:, determine the BSR form that described UE selects according to the reserved bit position in the MAC head among the BSR of MAC CE form.

Owing to have only two R bit in MAC among the BSR of MAC CE form, so this method only is applicable to that BSR table number is smaller or equal to 4 situation.

Suppose to have 4 BSR table, then the corresponding relation of R bit in the BSR MAC head and BSR table can be as shown in table 4, and the R bit value of the BSR table of R8 is 00.Certainly BSR table and R bit value can also adopt other corresponding relation, have just given an example shown in the table 4:

The corresponding relation of table 4R bit and BSR table

RR bit value	BSR table numbering
		00	1
01	2
		10	3
11	4

3) partly increase BSR form numbering indication territory by MAC CE among the BSR of MAC CE form, indicate selected BSR form

End side: MAC CE partly introduces new table index indication territory indication BSR table numbering in the BSR of MAC CE form;

In order to distinguish mutually with the BSR MAC CE form of Rel-8, by MAC head among the BSR of described MAC CE form, indicate this BSR to increase BSR form numbering indication territory, particularly, can indicate this BSR to increase BSR form numbering indication territory by logical channel number LCID territory or the reserved bit position Rbit in the MAC head among the BSR of MAC CE form.

Base station side:, determine that this BSR has increased BSR form numbering indication territory according to MAC head among the BSR of described MAC CE form; According to the BSR form numbering indication territory that increases among the described BSR, determine the BSR form that described UE selects.

The new BSR form numbering indication territory bit size of introducing depends on the number of BSR table, gets 2 such as the BSRtable number, and then table index uses 1bit to represent that the BSRtable number gets 3 or 4, and then tableindex uses 2bit to represent; BSR table number is got 5 to 8, and then table index represents with 3bit.With 2 BSR table is example, and being depicted as Fig. 6 a has increased the form that BSR form numbering is indicated weak point/brachymemma BSR of territory table index, and Fig. 6 b is the form that has increased the long BSR of BSR form numbering indication territory table index.

If two BSR table of use in the CA system, one of them BSR table are the Rel-8 compatibility, tableindex gets 0, and the table index of the new BSR table that introduces gets 1, and based on this hypothesis, embodiments of the invention are as follows.
