In LTE system, BSR is used for representing the size of data volume in the terminal buffers that is allowed to of terminal.According to the regulation of LTE project, the largest buffered data volume of terminal support is 150K.In addition, in LTE system, BSR has three types usually: long BSR, short BSR and brachymemma BSR.Wherein, long BSR can report the buffer status of four logic channel groups.

In order to transmit BSR between the base station and the terminal, in base station and terminal, be provided with BSR concordance list.In BSR concordance list, according to technological document 1 (3GPPRAN2document, R2-083101, " BufferSizeLevelsforBSRinE-UTRAUplink ") method, be multiple minizone by the interval division of 0 to 150K, the call number of each minizone corresponds to a scope of data volume size in buffer memory.Wherein, the full content of technological document 1 is incorporated herein by reference.Therefore, base station and terminal can be reported by the mode transmitting described call number and be obtained the scope (i.e. BSR) of data volume size in buffer memory.

Specifically, terminal finds out call number according to the size of data volume in own cache in BSR concordance list, and this call number is reported base station, base station obtains the scope (i.e. BSR) of data volume size in buffer memory according to described call number from BSR concordance list.

In LTE project, define and report above-mentioned call number by 6 bit word.Therefore, in this case, can, according to the method for technological document 1, be 64 minizones by the interval division of 0 to 150K.And the corresponding relation of the magnitude range of the call number of each minizone and corresponding buffer data size is stored form BSR concordance list.

Figure 10 shows the example of the BSR concordance list in existing LTE system.Can find out, when largest buffered data volume is more than 150K in the buffer, this BSR concordance list can only indicate current data volume cannot provide numerical value or number range more specifically more than 150K.

Along with freezing of LTE project, start the research for forth generation mobile communication system (senior Long Term Evolution project, LTE-Advanced, LTE-A) technology at present.In lte-a system, propose the requirement to more high data rate, such as, the high data rate requirement of descending 1Gbps, up 500MGbps.

Can be the existing BSR concordance list shown in Figure 10 see Fig. 1, BSR concordance list 102.Such as, the data cached scope of this BSR concordance list 102 is such as from 0 to 150K, and is divided into 64 minizones according to the method for technological document 1.But BSR concordance list 102 is not limited thereto.Such as, data cached scope not necessarily from 0 to 150K, and can be other any scope.And minizone number also not necessarily 64, and can be other any quantity.However, be still described for 0 to 150K and 64 minizones in the following description.

See Fig. 1, expansion BSR concordance list 104 can be the concordance list for expanding to adapt to higher message transmission rate to existing BSR concordance list.

In one embodiment, relation in succession can be there is with the data cached weight range of BSR concordance list 102 in the data cached weight range expanding BSR concordance list 104.Such as, the lower limit of the data cached weight range in expansion BSR concordance list 104 can be the upper limit of the data cached weight range in BSR concordance list 102, such as 150K; And the upper limit of the described data cached weight range expanded in BSR concordance list 104 can be largest buffered data volume that is that specify in consensus standard or that determine according to practical situations, such as 1200K or 1500K.

In another embodiment, inclusion relation can be there is with the data cached weight range of BSR concordance list 102 in the data cached weight range expanding BSR concordance list 104.Such as, expansion BSR concordance list 104 can be the expansion BSR concordance list according to technological document 2.In this case, the lower limit of data cached weight range of expansion BSR concordance list 104 is identical with the lower limit of the data cached weight range of BSR concordance list 102, such as, can be 0; And the upper limit expanding the data cached weight range of BSR concordance list 104 can be such as largest buffered data volume that is that specify in consensus standard or that determine according to practical situations, such as 1200K or 1500K.

In addition, for expansion BSR concordance list 104 and BSR concordance list 102, by various suitable method, its data cached weight range can be divided into multiple minizone.Such as, by the method for technological document 1, its data cached weight range can be divided into multiple minizone.Figure 12 and 13 respectively illustrates the expansion BSR concordance list obtained by the method for technological document 1, and wherein, data cached weight range is from 150K to 1200K and from 150K to 1500K respectively.But expansion BSR concordance list 104 is not limited thereto.Such as, minizone number also not necessarily 64, and can be other any quantity.However, be still described for 64 minizones in the following description.

In addition, along with further developing of the communication technology, terminal needs the data volume reported to increase further, thus, also can adopt multiple expansion BSR concordance list.When there is multiple expansion BSR concordance list, data cached weight range of each expansion BSR concordance list can be relation in succession, also can be inclusion relation.

In one embodiment of the invention, can be relation in succession between the data cached weight range of each expansion BSR concordance list.Specifically, can the data volume reported be needed to be divided into several continuous print segment terminal, each segment be represented by an expansion BSR concordance list.

In another embodiment of the present invention, can be inclusion relation between the data cached weight range of each expansion BSR concordance list.Specifically, each expansion BSR concordance list has the lower limit of identical data cached scope, such as 0K; But each expansion BSR concordance list has the upper limit of different data cached scopes to adapt to various different data rate.

Get back to Fig. 1, selection result for selecting a concordance list in buffer status concordance list 102 and at least one expansion buffer status concordance list 104, and is informed to index determiner 108 by concordance list selector 106.In addition, concordance list selector 106 can carry out selecting and by indication signaling, selection result being informed to base station on one's own initiative, or also can carry out passively selecting (Fig. 1 is not shown) according to the indication signaling from base station.

In one embodiment, concordance list selector 106 can select a concordance list in buffer status concordance list 102 and at least one expansion buffer status concordance list 104 passively according to the indication signaling from base station.Specifically, concordance list selector 106 receives indication signaling from base station, determines to select which concordance list, and selection result is informed to index determiner 108 according to this indication signaling.

And in another embodiment, concordance list selector 106 can select a concordance list in buffer status concordance list 102 and at least one expansion buffer status concordance list 104 on one's own initiative, then selection result is directly notified index determiner and by indication signaling, selection result is informed to base station.

When concordance list selector 106 is initiatively selected, first concordance list selector 106 according to terminal buffers data volume or can select concordance list according to terminal type and terminal buffers data volume.

In one embodiment, concordance list selector 106 can select concordance list according to terminal buffers data volume.Such as, when concordance list selector 106 finds that the size of terminal buffers data volume is in 0 scope to 150K, BSR concordance list 102 selected by concordance list selector 106; And when concordance list selector 106 finds the size of terminal buffers data volume more than 150K, expansion BSR concordance list 104 selected by concordance list selector 106.In addition, when there is multiple expansion BSR concordance list, concordance list selector 106 can be selected to expand BSR concordance list accordingly according to the size of terminal buffers data volume.

In another embodiment, concordance list selector 106 can select concordance list according to terminal type and terminal buffers data volume.Such as, when concordance list selector 106 finds that terminal is LTE equipment, buffer status concordance list 102 selected by concordance list selector 106.And when concordance list selector 106 finds that terminal is LTE-A equipment, concordance list selector 106 directly can select expansion buffer status concordance list 104, or also can select further combined with terminal buffers data volume, that is: when the size of terminal buffers data volume is in 0 scope to 150K, buffer status concordance list 102 is selected; And the size of terminal buffers data volume more than 150K time, select expansion buffer status concordance list 104.And when there is multiple expansion BSR concordance list, concordance list selector 106 can directly be selected to expand BSR concordance list accordingly according to the size of terminal buffers data volume.

Then, selection result directly can be notified index determiner 108 by concordance list selector 106, and by indication signaling, selection result is informed to base station.

No matter can find out, be that concordance list selector carries out selecting or selecting passively on one's own initiative, needs to transmit by indication signaling the information corresponding to which concordance list about index between terminal and base station.Wherein, indication signaling can be various suitable protocol messages, such as, indication signaling can be radio resource control layer (RadioResourceControl, RRC) signaling or media access control layer (MediaAccessControl) signaling.

When terminal receives indication signaling from base station and selects concordance list according to this indication signaling, indication signaling can be such as RRC signaling.

In one embodiment, concordance list selector 106 can receive to determine to select which concordance list as the RRC signaling of indication signaling from base station.Such as, as shown in Figure 5, concordance list selector 106 can determine to select which concordance list from the base station concordance list indication information received RRC connection establishment (RRCConnectionSetup) signaling.

On the other hand, when terminal initiatively select BSR concordance list and by indication signaling by selection result informing base station, RRC signaling or MAC signaling can be come to the concordance list selected by the notice of base station as indication signaling by the concordance list selector 106 in terminal, and namely informing base station corresponds to which the information in BSR concordance list and BSR expansion buffer status concordance list about the index received by base station.

In one embodiment, RRC signaling can be come to the concordance list selected by the notice of base station as indication signaling by concordance list selector 106.

In a specific embodiment, such as, as shown in Figure 5, concordance list selector 106 can complete (RRCConnectionSetupComplete) signaling to the concordance list selected by the notice of base station by RRC connection request (RRCConnectionRequest) signaling or RRC connection establishment comprising concordance list indication information to base station transmission.

In another embodiment, MAC signaling can be come to the concordance list selected by the notice of base station as indication signaling by concordance list selector 106.

In a specific embodiment, concordance list selector 106 can utilize which the logical channel identifier (LogicChannelIdentity, LCID) in MAC signaling is to the concordance list selected by the notice of base station.Specifically, when BSR value comes from expansion BSR concordance list 104, define a new LCID for long BSR, short BSR and brachymemma BSR respectively, concordance list selector 106 can utilize the value of the LCID of this new definition to use expansion BSR concordance list to the type and terminal that represent BSR.And when BSR value comes from BSR concordance list 102, concordance list selector 106 can utilize defined LCID value in current agreement to be BSR concordance list 102 to represent that terminal uses.

Such as, as shown in Figure 6, define three new LCID values 01011,01100 and 01101, wherein: LCID=01011 represents that the BSR in this MAC signaling is long BSR, and the value of BSR comes from expansion BSR concordance list; LCID=01100 represents that the BSR in this MAC signaling is short BSR, and the value of BSR comes from expansion BSR concordance list; LCID=01101 represents that the BSR in this MAC signaling is brachymemma BSR, and the value of BSR comes from expansion BSR concordance list.Like this, according to the LCID value of these three newly definition, terminal can represent that the type of BSR and selected concordance list are expansion BSR concordance list.In addition, the logical value shown in Fig. 6 is only example and is not construed as limiting, and obviously can also adopt the logical value of other suitable form.

In this specific embodiment, the LCID value by newly defining achieves in a straightforward manner to the base station notice type of BSR and the type of BSR concordance list.But four the logic channel groups in this specific embodiment, do not distinguished in long BSR.That is, which concordance list the BSR not indicating all logic channel groups such as BS#0 to the BS#3 in long BSR particularly comes from.

In order to select suitable concordance list based on the data volume of each logic channel group more accurately, each the logic channel group showing terminal to base station is needed to employ which concordance list.Therefore, in another specific embodiment, can increase an extra byte in MAC signaling, concordance list selector 106 utilizes at least part of bit in the LCID in MAC signaling and this extra byte which to be to base station notification terminal for the concordance list selected by each logic channel group.

Specifically, for short BSR or brachymemma BSR, similar with a upper specific embodiment, by LCID value defined in current agreement, concordance list selector 106 represents that terminal uses is BSR concordance list 102, and representing that terminal uses by the LCID value newly defined is expansion BSR concordance list 104.In another embodiment, also can without the need to defining new LCID, and represented by the bit of in extra byte and use BSR concordance list still to expand BSR concordance list, to the description of the situation of long BSR below this situation is similar to.

For long BSR, the BSR of four logic channel groups in long BSR all can represent with BSR concordance list 102 (such as, the buffer data size reported in each logic channel group is all less than the situation of 150K), concordance list selector 106 can represent this situation by LCID value existing in agreement.And the one or more BSR in four logic channel groups in long BSR are applicable to expand the situation of BSR concordance list 102 (such as, the buffer data size reported at least one logic channel group is more than the situation of 150K) under, concordance list selector 106 can utilize new LCID value to represent the type of BSR and be long BSR and not all to use BSR concordance list, and which concordance list the BSR of four the logic channel groups represented further in this long BSR by four in extra byte takes from respectively.Specifically, concordance list selector 106 can utilize the LCID value of existing LCID value or new definition to represent that the type of BSR is long BSR, and which BSR concordance list the BSR of four the logic channel groups represented in this long BSR further by four in LCID value and extra byte takes from respectively.But, also can not define new LCID and only use original LCID.Now, LCID is only used for representing the type of BSR, and represents which concordance list is each logic channel group correspond to by the bit in described extra byte completely.

Such as, as shown in Figure 7: which concordance list the BSR of four logic channel groups that concordance list selector 106 utilizes rear four (BTI0, BTI1, BTI2, BTI3) in extra byte to represent in long BSR takes from respectively.Such as, when the value of LCID correspond to long BSR and (BTI0, BTI1, BTI2, BTI3)=1010 time, can represent that the value of the BSR of logic channel group BS#0 in this long BSR and BS#2 comes from expansion BSR concordance list 104; And the value of the BSR of logic channel group BS#1 and BS#3 comes from BSR concordance list 102.In addition, the logical bit shown in Fig. 7 arranges and is only example and is not construed as limiting, and the logical bit of other suitable form obviously can also be adopted to arrange.Such as, not necessarily utilize latter four and can be other four in extra byte, BSR concordance list 102 can be represented with 1 and with 0 representative expansion BSR concordance list etc.

In addition, in another specific embodiment, concordance list selector 106 can utilize which the reserved bit position in the LCID in MAC signaling and sublist head is to the concordance list selected by the notification terminal of base station.Specifically, two reserved places in the sum-bit sublist head in LCID value can be utilized which to be to base station notification terminal for the concordance list selected by each logic channel group.

Consider in current LTE system, span is the LCID value of 01011-11001 is reserved LCID, therefore, as shown in Figure 8, concordance list selector 106 can utilize the first two reserved place RR in last two and the sublist head of 10000,10001,10010 and 10011 these four LCID values to represent which terminal pins is to the concordance list selected by each logic channel group.

Such as, work as RR=00, during LCID=10011, can represent that BSR is long BSR, and the value that the value of the BSR of logic channel group BS#0 in this long BSR and BS#1 comes from the BSR of BSR concordance list 102 and logic channel group BS#2 and BS#3 comes from expansion BSR concordance list 104.In addition, logical bit shown in Fig. 8 is arranged and selected LCID reserved value is only example and is not construed as limiting, obviously the logical bit of other suitable form can also be adopted to arrange and LCID reserved value, also can represent BSR concordance list 102 with 1 and expand BSR concordance list with 0 representative.
