In concrete application scenarios, when the base station receive that network equipment sends enable the message of a TBS form time, step S301 specifically transmits by following dual mode:
Mode one, base station receive the RRC message that comprises explicit information that RNC sends, the information of the TBS form that the explicit information indication is activated.
Mode two, base station receive the message of one or more appointments of network equipment transmission, and according to preset trigger rule, when the base station received the message of appointment, a corresponding TBS form was enabled in the base station.
Wherein, the TBS form that is activated specifically comprises following two kinds of situations:
TBS information in situation one, the TBS form is the type of distinguishing terminal not, all uses the corresponding TB size of TBS information in the TBS form to carry out data information transmission to all terminals.
The type of the TBS data separation terminal in situation two, the TBS form is enabled in the different TBS forms the corresponding TB size of corresponding TBS information respectively to dissimilar terminals and is carried out data information transmission.
In this case, corresponding dissimilar terminals has been stored different TBS forms respectively in the base station, at concrete terminal type, enable corresponding TBS form, and use corresponding TB size to carry out transfer of data
Wherein, the set-up mode of corresponding TBS information specifically comprises in the above-mentioned TBS form:

On the other hand, when the base station receives the message of one or several TBS information in the renewal TBS form that network equipment sends, step S301 is specially the base station and receives the RRC message that comprises explicit information that RNC sends, and explicit information comprises the positional information of TBS lastest imformation and the TBS information that need be updated.
Wherein, the TBS lastest imformation is specially:
A plurality of TBS information with different numerical values recited, wherein, the terminal type that the TBS information of different numerical values recited is corresponding different respectively; Or,
The TBS information of a numerical value variable size, corresponding dissimilar terminals.
Step S302, base station send data message by TBS form that is activated or the pairing transmission block TB of the TBS form size that is updated to terminal according to this message.
More than be the application flow of technical solution of the present invention in base station side, for the application flow of clearer explanation technical solution of the present invention, the present invention is by the application flow of subsequent embodiment explanation technical solution of the present invention in end side.
As shown in Figure 4, be the schematic flow sheet of a kind of data transmission method that the embodiment of the invention proposed, in the application scenarios of this method, stored one or more TBS forms that comprise multiple TBS information in base station and the terminal respectively, specifically may further comprise the steps:
Step S401, terminal receive the message of enabling one or several TBS information in a TBS form or the renewal TBS form that network equipment sends;
Wherein, comprise the TBS information of numerical values recited in TBS form that is activated or the TBS lastest imformation less than presently used TBS information value size, further refinement interruption being set or tying up current applied TBS standard like this can use littler TB to carry out transfer of data thereby make between base station and the terminal.
On the one hand, when terminal receive that network equipment sends enable the message of a TBS form time, this step specifically comprises following two kinds of implementations:
Mode one, terminal receive the RRC message that comprises explicit information that RNC sends, the information of the TBS form that the explicit information indication is activated.
Mode two, terminal receive the message of one or more appointments of network equipment transmission, and according to preset trigger rule, when terminal received the message of appointment, terminal was enabled a corresponding TBS form.
On the other hand, when terminal receives the message of one or several TBS information in the renewal TBS form that network equipment sends, the specific implementation of this step is that terminal receives the RRC message that comprises explicit information that RNC sends, and explicit information comprises the positional information of TBS lastest imformation and the TBS information that need be updated.
Step S402, terminal receive the data message that the base station sends according to this message by TBS form that is activated or the pairing TB size of the TBS information that is updated;
Compared with prior art, the embodiment of the invention has the following advantages:
By using the technical scheme of the embodiment of the invention, the base station can use the transmission block that mates more that UE is dispatched, and the line data of going forward side by side transmission has avoided using the excessive problem that causes the wasting of resources of TB piece in the existing standard.
Below, the application scenarios in conjunction with concrete describes the technical scheme that the embodiment of the invention proposed.
As shown in Figure 5, a kind ofly for the embodiment of the invention proposed use amended TBS form to carry out the schematic flow sheet of the method for transfer of data, specifically may further comprise the steps:
Step S501, network equipment are revised the TBS form, generate the TBS lastest imformation.
Because the TB block size of TBS index=0 correspondence is empty in the existing standard, promptly can't be as normal HSDPA scheduling.
In the technical scheme of the embodiment of the invention, network equipment has been revised the pairing TB block size of field of the TBS index=0 in the TBS form, has generated one greater than 0 and less than the TB block size of 240 bits.
Wherein, specifically comprise two kinds of modes that generate the TBS lastest imformation:
Stipulate one or more fixing TB block sizes, TBS index=0 is the value of NULL in the replacement existing standard.Stipulate that a fixing TB block size is meant and do not distinguish the UE type, the TB block size of all types of UE TBS index=0 correspondences is a fixing TB block size of redetermination.Stipulate a plurality of TB block sizes, then can define different TB block sizes respectively for different UE types.
Perhaps, the TB piece of a variable size of regulation is disposed to terminal by high-level signaling by network side.Afterwards, the TB block size that disposes as high-level signaling of the TB block size that uses by TBS index=0 indication scheduling of base station.Concrete indicating mode is for example:
Because existing TB block size minimum is 240 bits, so, use the concrete TB block size of 8 bits indication, indicating corresponding TB block size respectively is 0 to 239.
Perhaps set the TB block size and change,, use 5 bits indications TB block size as being granularity with 10 bits with certain particle size, respectively Zhi Shi TB block size be 0,10,20 ..., 230.
Step S502, network equipment informing base station and terminal are used the TBS lastest imformation.
Owing to revised original TBS form, network needs indicating terminal whether to use TBS form after being modified, promptly uses above-mentioned TBS lastest imformation.
Concrete indicating mode comprises following two kinds:
Mode one, network equipment are by RRC signaling explicit notification
Whether network equipment (for example RNC) uses amended TBS form by RRC signaling explicit notification terminal.
Concrete explicit notification mode is for example: use 1 bit in the RRC signaling, amended TBS form is used and is not used in expression respectively.
Perhaps for example: as previously mentioned, network is that new TB block size of terminal configuration replaces TBS Index=0 by the RRC signaling, is not 0 for the TB block size that disposes, and then uses amended TBS form.
Mode two, network equipment use the TBS lastest imformation by agreement indication triggering terminal and base station
(1) make an appointment a certain characteristic when coming into force, amended TBS form is used in terminal and base station.
For example, when descending SPS comes into force, when promptly HS_DSCH_SPS_STATUS is TRUE, from revise back TBS form, select for the TB block size of descending SPS scheduling and corresponding retransmission use.
Again for example, use amended TBS form in CELL_FACH increases, promptly HS_DSCH_DRX_CELL_FACH_STATUS is TRUE.
Again for example, after L2 strengthens startup, use amended TBS form.
(2) the make an appointment terminal of a certain version is used amended TBS form.
For the situation of the TB block size of only revising TBS index=0 correspondence, arrange the amended TBS form of the fixing use of terminal of a certain version.
Step S503, base station are carried out transfer of data by the pairing TB block size of TBS information after upgrading to terminal.
As shown in Figure 6, a kind of schematic flow sheet that uses newly-built TBS form to carry out the method for transfer of data for the embodiment of the invention proposed specifically may further comprise the steps:
Step S601, network equipment are created one or more new TBS forms.
Wherein, so-called new TBS form specifically is meant the TBS form that is different from existing TBS form, comprises the TBS information less than TBS information value minimum in the existing TBS form in new TBS form, and concrete TBS form establishment mode comprises following two kinds:
Mode one, do not distinguish the UE ability, unifiedly create a new TBS form
Be that the embodiment of the invention can only define a new TBS form, and needn't distinguish the applied terminal type of this TBS form.
Concrete for example as: be new TBS form of descending SPS definition, concrete TB block size can be determined according to the typical services that SPS supports.
Again for example, new TBS form of definition strengthens as CELL_FACH.
Mode two, differentiation UE ability are that dissimilar terminals is created different new TBS forms
It is to be noted, in this mode, can all not define new form, but adopt the mode in the similar existing standard for each terminal type, for several terminal types define same TBS form, and use the corresponding different terminal type of different TBS information in this TBS form.
What need further specify is that in concrete application scenarios, above-mentioned new TBS form can be determined according to typical services, also can use following manner to revise with reference to existing TBS form:
(1) numerical value of the minimum TBS information in the existing TBS form of reduction keeps the maximum of TBS information constant, still adopts the mode of geometric ratio to produce TBS.
(2) adjust the numerical value of the minimum TBS information in the existing TBS form, and in the less interval of TBS information, be set to the mode of equal difference, and be set to the mode of geometric ratio in the bigger interval of TBS information.
Concrete application is carried out which kind of above-mentioned mode the establishment of TBS form, can't influence protection scope of the present invention.
Step S602, network equipment informing base station and terminal are used new TBS form.
Owing to created new TBS form, network needs indicating terminal whether to use new TBS form.
Concrete indicating mode comprises following two kinds:
Mode one, network equipment are by RRC signaling explicit notification
Whether network equipment (for example RNC) uses new TBS form by RRC signaling explicit notification base station and terminal.
Concrete explicit notification mode is that network equipment generates the new pairing indication information of TBS form, and by RRC signaling base station and terminal.
Mode two, network equipment use new TBS form by agreement indication triggering terminal and base station
(1) make an appointment a certain characteristic when coming into force, new TBS form is used in terminal and base station.
For example, define a new TBS form and strengthen as CELL_FACH, network and terminal agreement use new TBS form or network indicating terminal whether to use new TBS form.
Again for example, after L2 strengthens startup, use the TBS form of redetermination.
Again for example, when network was UE configuration HS-DSCH SPS information by the RRC signaling, the TB block size of TransportBlock Size Index correspondence was determined according to new TBS form.
(2) the make an appointment terminal of a certain version is used new TBS form.
Arrange the new TBS form of the fixing use of terminal of a certain version.
Step S603, base station are carried out transfer of data by the many corresponding TB sizes of the TBS information after upgrading to terminal.
Compared with prior art, the embodiment of the invention has the following advantages:
By using the technical scheme of the embodiment of the invention, the base station can use the transmission block that mates more that UE is dispatched, and the line data of going forward side by side transmission has avoided using the excessive problem that causes the wasting of resources of TB piece in the existing standard.
In order to realize the technical scheme of the embodiment of the invention, the embodiment of the invention also provides a kind of base station, and its structural representation comprises as shown in Figure 7:
In concrete application scenarios, the set-up mode of corresponding TBS information specifically comprises in the TBS form of being stored in the memory module 71:
Revise the TBS information maximum or the TBS information minimum value of described TBS form, between TBS information maximum and TBS information minimum value, set different big or small TBS information according to the mode that geometric ratio is set; Or,
