Put.
Various embodiments of the present invention are described as a example by the Rel11 LTE standard as redaction.Should refer to
Going out, it is only a kind of citing and non-limiting.For what the follow-up evolution version of Rel11 was likely to occur
Other special subframes configure, it is also possible to conceived by inventions based on above-mentioned several solutions so that base station
Know whether the LTE terminal of earlier version supports that this special subframe configures.
If Rel11 is redaction LTE standard, above-mentioned new special subframe is configured to redaction LTE mark
The special subframe configuration of regulation in standard.In the embodiment of the present invention, the TD-LTE terminal of the earlier version of indication is
Refer to, the TD-LTE terminal of Rel9/Rel10.Can be specifically the TD-LTE terminal of Rel9, it is also possible to be
The TD-LTE terminal of Rel10.
If redaction LTE standard refers to the follow-up evolution version of Rel11.Indication in the embodiment of the present invention
The TD-LTE terminal of earlier version is the related versions terminal for the follow-up evolution version of Rel11.
Such as, the TD-LTE terminal of Rel11, the TD-LTE terminal of Rel10, the TD-LTE terminal etc. of Rel9
All can be as the TD-LTE terminal of the earlier version for the later release of relative Rel11.
Below in conjunction with accompanying drawing, above-mentioned three kinds of implementations are described in detail respectively.
Based on above-mentioned (one) the invention conception planting implementation, in order to make base station know the LTE of earlier version
Whether terminal supports the special subframe configuration of regulation in redaction LTE standard, the one of embodiment of the present invention offer
Plant and be achieved in that: a reserved FGI bit is defined, using this reserved FGI bit as specifically
FGI bit, specific special subframe configures (i.e. in redaction LTE standard to be used for indicating terminal whether to support
The special subframe configuration of regulation).Such as, by definition, it is stipulated that the value of this FGI bit is 1, represent eventually
End supports the configuration of specific special subframe, and the value of this FGI bit is 0, represents that terminal does not support specific spy
Different sub-frame configuration, vice versa.
Accordingly, as it is shown in figure 1, embodiments provide the data transmission method of a kind of end side,
Its implementation includes operating as follows:
Step 100, support that the TD-LTE terminal of the earlier version that specific special subframe configures arranges specific
The value of FGI bit, to represent that this terminal supports the configuration of specific special subframe；
The UE capability reporting message comprising the specific FGI bit after arranging is sent out by step 110, this terminal
Give base station.
As in figure 2 it is shown, embodiments provide the data transmission method of a kind of base station side, its realization side
Formula includes operating as follows:
Step 200, base station obtain in the UE capability reporting message of TD-LTE terminal transmission of earlier version
The value of the specific FGI bit comprised；
According to the value of above-mentioned specific FGI bit, step 210, this base station judge whether above-mentioned terminal supports spy
Fixed special subframe configuration.
Reserved FGI bit is defined, by the specific FGI bit instruction earlier version of new definition
Whether TD-LTE terminal supports that specific special subframe configures, it is possible to scheduling downstream transmission accordingly, effectively
Improve the effectiveness of downlink transfer.
There is a kind of situation, only under some special scenes, the TD-LTE terminal of earlier version is supported specific
Special subframe configuration.So, terminal can decide whether to meet the bar supporting the configuration of specific special subframe
The most whether part (is in special scenes), if it is, perform above-mentioned steps 100.Accordingly, base station is permissible
Judge whether terminal meets the condition (i.e. whether terminal is in special scenes) supporting the configuration of specific special subframe,
If it is, perform above-mentioned steps 210.
As a example by the TD-LTE terminal of the Rel9/Rel10 supporting special subframe configuration new in above-mentioned Rel11.
By definition, determine that a reserved FGI bit, as specific FGI bit, is used for indicating whether terminal props up
Hold special subframe configuration new in Rel11.In order to avoid there is conflict definitions, preferably with follow-up evolution version
, determine that reserved FGI bit that bit number is bigger is as specific FGI bit, such as FGI bit
64。
Assume FGI bit 64 as specific FGI bit, and when regulation FGI bit 64 takes 1,
Represent that terminal supports special subframe configuration new in Rel11, when FGI bit 64 takes 0, represent that terminal is not propped up
Hold special subframe configuration new in Rel11, and the default value of FGI bit 64 is 0.Accordingly, in support
The TD-LTE terminal of the Rel9/Rel10 stating special subframe configuration new in Rel11 reports UE ability
During, the value of the FGI bit 64 in UE capability reporting message is set to 1；Terminal passes through UE energy
The FGI bit 64 that value is 1 is sent to base station by power reporting message.At network side, base station receives
After the UE capability reporting message that the TD-LTE terminal of Rel9/Rel10 sends, therefrom obtain FGI bit 64
Value, if the value of FGI bit 64 is 1, determine that this terminal supports that the new special subframe in Rel11 is joined
Put, otherwise, it determines this terminal does not support that special subframe new in Rel11 configures.
Preferably, the specific implementation of above-mentioned steps 210 may is that base station judges Rel9/Rel10's
Whether the current service cell of TD-LTE terminal uses specific special subframe to configure, if it is, according to
The value of the specific FGI bit that the TD-LTE terminal of Rel9/Rel10 sends judges whether this terminal supports spy
Fixed special subframe configuration；Otherwise, it is switched to, when base station, the Serving cell that uses specific special subframe to configure
When carrying out data transmission with this terminal, the value of the specific FGI bit that this base station sends according to this terminal judges should
Whether terminal supports that specific special subframe configures.
It is to say, only the Serving cell in the TD-LTE terminal of Rel9/Rel10 uses specific special son
During frame configuration, base station just judges whether this terminal supports that specific special subframe configures.
There is a kind of situation is: at the TD-LTE of the earlier version of a certain area (dividing according to HPLMN)
Terminal all supports that the special subframe specified in the LTE standard of redaction configures, and the earlier version in other areas
TD-LTE terminal not necessarily support the special subframe configuration of regulation in the LTE standard of redaction.This feelings
Under condition, the base station in other areas is also not necessarily required to know whether the TD-LTE terminal of earlier version is supported newly
The special subframe configuration of regulation in the LTE standard of version.As a example by the TD-LTE terminal of Rel9/Rel10.
At present, the TD-LTE terminal of domestic Rel9/Rel10 all supports that special subframe new in Rel11 configures,
But the TD-LTE terminal of external Rel9/Rel10 not necessarily supports that special subframe new in Rel11 configures.
Therefore, external base station is also not necessarily required to know whether the TD-LTE terminal of Rel9/Rel10 is supported
Special subframe configuration new in Rel11.Based on such background, can specify that domestic Rel9/Rel10's
When TD-LTE terminal roams abroad, it is not reported to support special subframe configuration new in Rel11.Accordingly
, the specific implementation of above-mentioned steps 100 may is that the PLMN (public land that terminal judges selects
Mobile network) whether it is HPLMN (ownership place public land mobile network)；If the PLMN selected
Being HPLMN, this terminal arranges the value of above-mentioned specific FGI, to represent that this terminal supports specific special son
Frame configures, if the PLMN selected is not HPLMN, then this terminal arranges above-mentioned specific FGI bit
Value so that it is represent that this terminal does not support that specific special subframe configures.Owing to the default value of FGI bit is 0,
If defining specific FGI bit value is to represent when 0 not support that specific special subframe configures.So this terminal
The value of above-mentioned specific FGI bit is set so that it is represent that this terminal does not support that specific special subframe configures, real
It is exactly the value of specific FGI not to be modified on border.
Such as, the NAS layer (Internet) of the TD-LTE terminal of domestic Rel9/Rel10 is carrying out PLMN
During selection, it is judged that whether the PLMN of selection is HPLMN, and the result that will determine that is sent to AS layer and (connects
Enter layer).AS layer preserves the result judged, and during carrying out UE capability reporting, according to judge
Result arranges the value of specific FGI bit, if the PLMN selected is HPLMN, then by specific FGI
Value be set to 1, otherwise, the value of this specific FGI is set to 0.
In Rel11 as a example by above-mentioned new special subframe configuration.If to the TD-LTE terminal of Rel8 and
The TD-LTE terminal of Rel11 need not judge whether it supports that specific special subframe configures.Therefore, base
The TD-LTE terminal that may support the configuration of specific special subframe is identified by side needs of standing.
Preferably, before performing above-mentioned steps 200, the method for base station side can also include operating as follows: root
According to the version number of TD-LTE terminal, identify the TD-LTE terminal of described earlier version.
Based on above-mentioned (two) the invention conception planting implementation, in order to make base station know the LTE of earlier version
Whether terminal supports the special subframe configuration of regulation in redaction LTE standard, and the embodiment of the present invention also provides for one
Planting the data transmission method of base station side, its implementation is as it is shown on figure 3, specific implementation includes grasping as follows
Make:
Step 300, base station on DwPTS to the TD-LTE terminal scheduling downlink transfer of earlier version.
Wherein, base station on DwPTS to the TD-LTE terminal scheduling downlink transfer of earlier version, specifically
Referring to, base station sends PDCCH (physical down control to the TD-LTE terminal of earlier version on DwPTS
Channel processed) and PDSCH (Physical Downlink Shared Channel).
If this base station of step 310 receives the TD-LTE terminal of this earlier version for above-mentioned descending biography
Defeated correct feedback, it is determined that this terminal supports the configuration of specific special subframe.
By heuristically to the TD-LTE terminal scheduling downlink transfer of earlier version, judging whether it props up
Hold the configuration of specific special subframe, it is possible to scheduling downstream transmission accordingly, be effectively increased downlink transfer has
Effect property.This implementation need not eating dishes without rice or wine to add extra bit, the most there is not the risk of conflict definitions.
Transmission of feedback information is it could also be because unsuccessfully owing to base station is not properly received feedback, and nonterminal
Do not support that specific special subframe configures.And hence it is also possible to by repeatedly on DwPTS to earlier version
TD-LTE terminal scheduling downlink transfer determine whether terminal supports that specific special subframe configures.Accordingly
, if base station is not received by the terminal correct feedback for above-mentioned downlink transfer, it is judged that at DwPTS
On to this terminal send downlink transfer number of times whether arrive predetermined value, if it is, determine that this terminal is not propped up
Hold the configuration of specific special subframe, otherwise, to this terminal scheduling downlink transfer on DwPTS, to determine
Whether this terminal supports that specific special subframe configures.
Such as, the special subframe that the current service cell at the TD-LTE terminal place of Rel9/Rel10 is used
It is configured to special subframe configuration new in Rel11.The base station of current area on DwPTS to Rel9/Rel10
TD-LTE terminal scheduling downlink transfer；If it is correct anti-that this base station receives for above-mentioned downlink transfer
Feedback, it is determined that this terminal supports the configuration of specific special subframe；Otherwise, it determines this terminal is not supported specifically
Special subframe configures.Preferably, without receiving the correct feedback for above-mentioned downlink transfer, also may be used
Repeatedly to attempt sending downlink transfer to this terminal, to determine whether this terminal is supported specific on DwPTS
Special subframe configuration.
Preferably, before performing above-mentioned steps 300, the method for base station side can also include operating as follows: root
According to the version number of TD-LTE terminal, identify the TD-LTE terminal of described earlier version.
There is a kind of situation is: at the TD-LTE of the earlier version of a certain area (dividing according to HPLMN)
Terminal all supports that the special subframe specified in the LTE standard of redaction configures, and the earlier version in other areas
TD-LTE terminal not necessarily support the special subframe configuration of regulation in the LTE standard of redaction.This feelings
Under condition, it can be assumed that the TD-LTE terminal of the earlier version in other areas does not support the LTE standard of redaction
The special subframe configuration of middle regulation.As a example by the TD-LTE terminal of Rel9/Rel10.At present, domestic
The TD-LTE terminal of Rel9/Rel10 all supports that special subframe new in Rel11 configures, but external
The TD-LTE terminal of Rel9/Rel10 not necessarily supports that special subframe new in Rel11 configures.Based on so
Background, it can be assumed that it is new that the TD-LTE terminal of external Rel9/Rel10 is not the most supported in Rel11
Special subframe configures.
Accordingly, based on above-mentioned (three) inventive concept planting implementation, in order to make base station know in early days
Whether the TD-LTE terminal of version supports the special subframe configuration of regulation in redaction TD-LTE standard, this
Inventive embodiments also provides for the data transmission method of a kind of base station side, its implementation as shown in Figure 4, specifically
Implementation includes operating as follows:
Step 400, base station judge whether the TD-LTE terminal of earlier version is roaming terminal.
Wherein, roaming terminal refers to, the PLMN that terminal selects is not HPMN.
If the TD-LTE terminal of above-mentioned earlier version is not roaming terminal, then perform step 410, this base
Station determines that above-mentioned terminal supports the configuration of specific special subframe.
Preferably, if the TD-LTE terminal of above-mentioned earlier version is roaming terminal, then perform step 420,
This base station determines that above-mentioned terminal does not support that specific special subframe configures.
By judging the TD-LTE terminal whether roaming terminal of earlier version, judge whether it supports specific
Special subframe configuration, it is possible to scheduling downstream transmission accordingly, be effectively increased the effectiveness of downlink transfer.
This implementation need not eating dishes without rice or wine to add extra bit, the most there is not the risk of conflict definitions.
Concrete, by the TD-LTE terminal of earlier version, base station can know whether it is roaming terminal,
Can also know whether the TD-LTE terminal of earlier version is roaming terminal by equipment of the core network.
If by the TD-LTE terminal of earlier version, base station knows whether it is roaming terminal, it is specifically real
Existing mode can but be not limited only to:
The TD-LTE terminal of earlier version actively by whether the information reporting of roaming terminal to base station, or,
Whether the TD-LTE terminal of base station active obtaining earlier version is the information of roaming terminal.
If by core net, base station knows whether terminal is roaming terminal, can be with upgrade of network interface, such as,
Upgrading S1 interface.Its specific implementation can but be not limited only to: this base station is to equipment of the core network (such as
MME) S-TMSI (temporary user device identifier) of the LTE terminal of earlier version is sent, with request
Equipment of the core network sends the information of this terminal whether roaming terminal；This base station obtains disappearing of equipment of the core network feedback
Breath, wherein has 1 bit instruction information, and this instruction information is used for indicating whether above-mentioned terminal is roaming terminal.
Wherein, S-TMSI can be carried by extending existing message in base station, it is also possible to by upgrade of network interface,
Define new message and carry S-TMSI.The message carrying 1 bit instruction information of equipment of the core network feedback can
To be existing message, it is also possible to be the new message by upgrade of network interface definition.
Preferably, the specific implementation of above-mentioned steps 400 may is that the TD-LTE terminal of earlier version
When accessing the Serving cell that above-mentioned base station controls, this base station judges whether described terminal is roaming terminal；Or,
Above-mentioned base station is switched to the TD-LTE of Serving cell and the earlier version using specific special subframe to configure eventually
When end carries out data transmission, this base station judges whether described terminal is roaming terminal.
Preferably, before performing above-mentioned steps 400, the method for base station side can also include operating as follows: root
