Specific embodiment

In order to make base station know whether the TD-LTE terminal (such as TD-LTE terminal of Rel9/Rel10) of earlier version props up Above-mentioned new special subframe configuration is held, the embodiment of the invention provides following several solutions: (one) passes through specific FGI Whether (Feature Group Indication, the instruction of characteristic group) bit indication terminal supports above-mentioned new special subframe to match It sets.(2), base station is heuristically on DwPTS to terminal scheduling downlink transfer, if being not properly received terminal under this The feedback of row transmission, the terminal do not support above-mentioned new special subframe to configure.(3), base station judges whether terminal is that roaming is whole End, if it is roaming terminal, then it is assumed that it does not support above-mentioned new special subframe to configure, otherwise it is assumed that it supports new special son Frame configuration.

It is described so that Rel11 is the LTE standard of new version as an example in various embodiments of the present invention.It should be pointed out that It is only it is a kind of citing and it is non-limiting.Other special subframes being likely to occur in the subsequent evolution version of Rel11 are configured, It can be conceived by the invention based on above-mentioned several solutions, so that base station knows whether the LTE terminal of earlier version is supported Special subframe configuration.

If Rel11 is new version LTE standard, above-mentioned new special subframe is configured to specified in new version LTE standard Special subframe configuration.The TD-LTE terminal of signified earlier version refers in the embodiment of the present invention, the TD-LTE of Rel9/Rel10 Terminal.The TD-LTE terminal that specifically can be Rel9, is also possible to the TD-LTE terminal of Rel10.

If new version LTE standard refers to the subsequent evolution version of Rel11.Signified earlier version in the embodiment of the present invention TD-LTE terminal be related versions terminal for the subsequent evolution version of Rel11.For example, the TD-LTE of Rel11 Terminal, the TD-LTE terminal of Rel10, TD-LTE terminal of Rel9 etc. can be used as the later release of opposite Rel11 The TD-LTE terminal of earlier version.

Below in conjunction with attached drawing, above-mentioned three kinds of implementations are described in detail respectively.

The invention conception of implementation is planted, based on above-mentioned (one) in order to which the LTE terminal for making base station know earlier version is The configuration of special subframe specified in no support new version LTE standard, one kind provided in an embodiment of the present invention are achieved in that: to one A reserved FGI bit is defined, this is reserved FGI bit as specific FGI bit, is used to indicate whether terminal supports spy Fixed special subframe configuration (i.e. special subframe specified in new version LTE standard configures).For example, by definition, it is specified that the FGI The value of bit is 1, indicates that terminal supports specific special subframe configuration, and the value of the FGI bit is 0, indicates that terminal does not support spy Fixed special subframe configuration, vice versa.

Correspondingly, as shown in Figure 1, the embodiment of the invention provides a kind of data transmission method of terminal side, realization side Formula includes following operation:

Step 100 supports the TD-LTE terminal of the earlier version of specific special subframe configuration that specific FGI bit is arranged Value, to indicate that the terminal supports the configuration of specific special subframe;

UE capability reporting message comprising the specific FGI bit after setting is sent to base station by step 110, the terminal.

As shown in Fig. 2, implementation includes such as the embodiment of the invention provides a kind of data transmission method of base station side Lower operation:

Include in the UE capability reporting message that the TD-LTE terminal that step 200, base station obtain earlier version is sent is specific FGI bit value;

It is specific special that step 210, the base station according to the value of above-mentioned specific FGI bit judge whether above-mentioned terminal is supported Sub-frame configuration.

Reserved FGI bit is defined, it is whole by the TD-LTE of the specific FGI bit indication earlier version newly defined Whether end supports specific special subframe to configure, and can scheduling downstream transmission accordingly, effectively increase the effective of downlink transfer Property.

There are a kind of situations, and only under certain special scenes, the TD-LTE terminal of earlier version supports specific special son Frame configuration.So, terminal can decide whether to meet the condition for supporting specific special subframe configuration (i.e. whether in specific field Scape), if it is, executing above-mentioned steps 100.Correspondingly, base station, which may determine that whether terminal meets, supports specific special subframe The condition (i.e. whether terminal is in special scenes) of configuration, if it is, executing above-mentioned steps 210.

For supporting the TD-LTE terminal of Rel9/Rel10 of special subframe configuration new in above-mentioned Rel11.By fixed Justice determines that a reserved FGI bit as specific FGI bit, is used to indicate whether terminal supports special son new in Rel11 Frame configuration.In order to avoid there is the definition that conflicts with subsequent evolution version, it is preferred that determine the biggish reserved FGI ratio of bit number Spy is used as specific FGI bit, such as FGI bit 64.

Assuming that regarding FGI bit 64 as specific FGI bit, and when regulation FGI bit 64 takes 1, indicate that terminal is supported New special subframe configuration in Rel11 when FGI bit 64 takes 0, indicates that terminal does not support special subframe configuration new in Rel11, And the default value of FGI bit 64 is 0.Correspondingly, support the Rel9/Rel10 of special subframe configuration new in above-mentioned Rel11 TD-LTE terminal is set as 1 during reporting UE ability, by the value of the FGI bit 64 in UE capability reporting message;Terminal The FGI bit 64 that value is 1 is sent to base station by UE capability reporting message.In network side, base station receives Rel9/Rel10 TD-LTE terminal send UE capability reporting message after, therefrom obtain FGI bit 64 value, if the value of FGI bit 64 is 1, determine that the terminal supports the new special subframe configuration in Rel11, otherwise, it determines the terminal does not support spy new in Rel11 Different sub-frame configuration.

Preferably, the specific implementation of above-mentioned steps 210 may is that base station judges the TD-LTE terminal of Rel9/Rel10 Current service cell whether configured using specific special subframe, if it is, according to the TD-LTE terminal of Rel9/Rel10 The value of the specific FGI bit sent judges whether the terminal supports specific special subframe to configure;Otherwise, when base station is switched to When the serving cell and the terminal configured using specific special subframe is carried out data transmission, which sends according to the terminal The value of specific FGI bit judges whether the terminal supports specific special subframe to configure.

That is, only being configured in the serving cell of the TD-LTE terminal of Rel9/Rel10 using specific special subframe When, base station just judges whether the terminal supports specific special subframe to configure.

There are a kind of situations to be: supporting in the TD-LTE terminal of the earlier version of a certain regional (dividing according to HPLMN) The configuration of special subframe specified in the LTE standard of new version, and the TD-LTE terminal of the earlier version in other areas is not necessarily propped up Hold the configuration of special subframe specified in the LTE standard of new version.In this case, the base station in other areas is also not necessarily required to obtain Know whether the TD-LTE terminal of earlier version supports special subframe specified in the LTE standard of new version to configure.With Rel9/ For the TD-LTE terminal of Rel10.Currently, the TD-LTE terminal of domestic Rel9/Rel10 supports in Rel11 newly special Sub-frame configuration, but the TD-LTE terminal of external Rel9/Rel10 not necessarily supports special subframe configuration new in Rel11.Cause This, it is new special in Rel11 that external base station is also not necessarily required to know whether the TD-LTE terminal of Rel9/Rel10 is supported Sub-frame configuration.Based on such background, can specify that the TD-LTE terminal of domestic Rel9/Rel10 in roaming abroad, not on It is reported to support special subframe configuration new in Rel11.Correspondingly, the specific implementation of above-mentioned steps 100 may is that terminal is sentenced Whether the disconnected PLMN (public land mobile network) selected is for HPLMN (ownership place public land mobile network);If selection PLMN is HPLMN, which is arranged the value of above-mentioned specific FGI, to indicate that the terminal supports specific special subframe configuration, if The PLMN of selection is not HPLMN, then the value of above-mentioned specific FGI bit is arranged in the terminal, so that it is indicated that the terminal is not supported specific Special subframe configuration.Since the default value of FGI bit is 0, if defining indicates not support spy when specific FGI bit value is 0 Fixed special subframe configuration.So terminal value that above-mentioned specific FGI bit is arranged, makes it indicate that the terminal is not supported specifically Special subframe configuration, does not modify to the value of specific FGI actually.

For example, the NAS layer (network layer) of the TD-LTE terminal of domestic Rel9/Rel10 when carrying out PLMN selection, judges Whether the result of judgement is sent to AS layer (access layers) for HPLMN by the PLMN selected.AS layers save judgement as a result, simultaneously During carrying out UE capability reporting, the value of specific FGI bit is set according to the result of judgement, if the PLMN of selection is HPLMN then sets 1 for the value of specific FGI, otherwise, sets 0 for the value of the specific FGI.

By taking new special subframe configuration above-mentioned in Rel11 as an example.If to the TD-LTE terminal of Rel8 and the TD- of Rel11 LTE terminal does not need to judge whether it supports specific special subframe to configure.Therefore, base station side needs specific to that may support The TD-LTE terminal of special subframe configuration is identified.

Preferably, before executing above-mentioned steps 200, the method for base station side can also include following operation: according to TD-LTE The version number of terminal identifies the TD-LTE terminal of the earlier version.

The invention conception of implementation is planted, based on above-mentioned (two) in order to which the LTE terminal for making base station know earlier version is The configuration of special subframe specified in no support new version LTE standard, the data that the embodiment of the present invention also provides a kind of base station side pass Transmission method, implementation is as shown in figure 3, specific implementation includes following operation:

Step 300, base station are 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, in particular to, base station exists DwPTS is upper to the TD-LTE terminal of earlier version to be sent PDCCH (Physical Downlink Control Channel) and PDSCH (physical down is total Enjoy channel).

If step 310, the base station receive the TD-LTE terminal of the earlier version for the correct of above-mentioned downlink transfer Feedback, it is determined that the terminal supports specific special subframe configuration.

By heuristically to the TD-LTE terminal scheduling downlink transfer of earlier version, to judge whether it supports specifically Special subframe configuration, and can scheduling downstream transmission accordingly, effectively increase the validity of downlink transfer.The implementation is not required to It to eat dishes without rice or wine to add additional bit, also there is no the risks of conflict definition.

It it could also be because that transmission of feedback information fails since base station is not properly received feedback, and nonterminal is not supported Specific special subframe configuration.And hence it is also possible to by repeatedly on DwPTS to the TD-LTE terminal scheduling downlink of earlier version It transmits to determine whether terminal supports specific special subframe to configure.Correspondingly, if base station is not received by terminal for upper The correct feedback for stating downlink transfer judges whether reach predetermined value to the number that the terminal sends downlink transfer on DwPTS, such as Fruit is, it is determined that the terminal does not support specific special subframe to configure, otherwise, to the terminal scheduling downlink transfer on DwPTS, To determine whether the terminal supports specific special subframe to configure.

For example, special subframe used in current service cell where the TD-LTE terminal of Rel9/Rel10 is configured to New special subframe configuration in Rel11.The base station of current area is on DwPTS under the TD-LTE terminal scheduling of Rel9/Rel10 Row transmission;If the base station receives the correct feedback for above-mentioned downlink transfer, it is determined that the terminal is supported specific special Sub-frame configuration;Otherwise, it determines the terminal does not support specific special subframe to configure.Preferably, if be not received by for upper The correct feedback of downlink transfer is stated, can also repeatedly attempt to send downlink transfer to the terminal on DwPTS, to determine the terminal Specific special subframe whether is supported to configure.

Preferably, before executing above-mentioned steps 300, the method for base station side can also include following operation: according to TD-LTE The version number of terminal identifies the TD-LTE terminal of the earlier version.

There are a kind of situations to be: supporting in the TD-LTE terminal of the earlier version of a certain regional (dividing according to HPLMN) The configuration of special subframe specified in the LTE standard of new version, and the TD-LTE terminal of the earlier version in other areas is not necessarily propped up Hold the configuration of special subframe specified in the LTE standard of new version.In this case, it can be assumed that the earlier version in other areas TD-LTE terminal does not support special subframe specified in the LTE standard of new version to configure.With the TD-LTE terminal of Rel9/Rel10 For.Currently, the TD-LTE terminal of domestic Rel9/Rel10 supports special subframe new in Rel11 to configure, but external The TD-LTE terminal of Rel9/Rel10 not necessarily supports special subframe configuration new in Rel11.It, can be false based on such background The TD-LTE terminal of fixed external Rel9/Rel10 does not support the new special subframe configuration in Rel11.

Correspondingly, planting the inventive concept of implementation, based on above-mentioned (three) in order to make base station know the TD- of earlier version Whether LTE terminal supports special subframe specified in new version TD-LTE standard to configure, and the embodiment of the present invention also provides a kind of base It stands the data transmission method of side, implementation is as shown in figure 4, specific implementation includes following operation:

Step 400, base station judge whether the TD-LTE terminal of earlier version is roaming terminal.

Wherein, roaming terminal refers to, the PLMN of terminal selection is not HPLMN.

If the TD-LTE terminal of above-mentioned earlier version is not roaming terminal, then follow the steps the 410, base station determine it is above-mentioned Terminal supports specific special subframe configuration.

Preferably, if the TD-LTE terminal of above-mentioned earlier version is roaming terminal, it is true to then follow the steps the 420, base station Fixed above-mentioned terminal does not support specific special subframe to configure.

By judge earlier version TD-LTE terminal whether roaming terminal, to judge whether it supports specific special son Frame configuration, and can scheduling downstream transmission accordingly, effectively increase the validity of downlink transfer.The implementation is not needed in sky Mouth adds additional bit, and also there is no the risks of conflict definition.

Specifically, base station can know whether it is roaming terminal by the TD-LTE terminal of earlier version, can also lead to It crosses equipment of the core network and knows whether the TD-LTE terminal of earlier version is roaming terminal.

If base station knows whether it is roaming terminal by the TD-LTE terminal of earlier version, specific implementation can With but be not limited only to:

The TD-LTE terminal of earlier version is actively by whether the information reporting of roaming terminal is to base station, alternatively, base station is actively Obtain earlier version TD-LTE terminal whether be roaming terminal information.

It, can be with upgrade of network interface, for example, upgrading S1 if base station knows whether terminal is roaming terminal by core net Interface.Its specific implementation can with but be not limited only to: the base station sends earlier version to equipment of the core network (such as MME) The S-TMSI (temporary user device identifier) of LTE terminal, with request equipment of the core network send the terminal whether roaming terminal Information;The base station obtains the message of equipment of the core network feedback, wherein there is 1 bit indication information, which is used to indicate State whether terminal is roaming terminal.Wherein, base station can carry S-TMSI by extending existing message, can also pass through upgrading Network interface defines new message and carries S-TMSI.The message of the 1 bit indication information of carrying of equipment of the core network feedback can be Existing message is also possible to the new message defined by upgrade of network interface.

Preferably, the specific implementation of above-mentioned steps 400 may is that the TD-LTE terminal of earlier version accesses above-mentioned base Stand control serving cell when, which judges whether the terminal is roaming terminal;Alternatively, above-mentioned base station is switched to using special When the fixed serving cell of special subframe configuration and the TD-LTE terminal of earlier version carries out data transmission, described in the judgement of the base station Whether terminal is roaming terminal.

Preferably, before executing above-mentioned steps 400, the method for base station side can also include following operation: according to TD-LTE The version number of terminal identifies the TD-LTE terminal of the earlier version.

The embodiment of the present invention also provides a kind of data processing method of core-network side, and implementation is as shown in figure 5, specific Implementation includes following operation:

Step 500, equipment of the core network receive the S-TMSI of the TD-LTE terminal for the earlier version that base station is sent;
