Certainly HARQ process number instructions field can also be further carried in above-mentioned up DCI, the instructions field can be existing There is the reuse of the existing bit number in up DCI format, for indicating that the PUSCH processes in special subframe are numbered, or be used for Indicate the PUSCH processes numbering in special subframe and common subframe.

Optionally, the instructions field for being used to indicate whether to retransmit is NDI.

The HARQ that aforesaid way 1~5 is applied to the PUSCH that the terminal is sent uses asynchronous system and the method for synchronization.

Aforesaid way 1~5 be may be used alone, can also be used in combination, and the embodiment of the present invention is not limited thereof.

In the embodiment of the present invention, if the terminal, in subframe m+k, detection is believed using the descending control of up DCI format Road, i.e., the PUSCH sent for the terminal HARQ use the method for synchronization, as a kind of possible embodiment, detection pair Answer the PUSCH's that is sent in the subframe common subframe corresponding with detection of the PUSCH sent in special subframe down control channel The subframe of down control channel is identical, and the k is defined as follows：

For TDD uplink-downlink configurations 0, if m is 1 or 6, the k is 4,5,9 or 10；Or

For TDD uplink-downlink configurations 2, if m is 1 or 6, the k is 2 or 7；Or

For TDD uplink-downlink configurations 3, if m is 1, the k is 7,8 or 9；Or

For TDD uplink-downlink configurations 4, if m is 1, the k is 7 or 8；Or

For TDD uplink-downlink configurations 5, if m is 1, the k is 7；Or

For TDD uplink-downlink configurations 6, if m is 6, the k is 3,4,5,9 or 10.

Because the subframe of the PUSCH sent in the corresponding special subframe of detection down control channel is corresponding with detection common sub The subframe of the PUSCH sent in frame down control channel is identical, and above-mentioned k definition makes special subframe corresponding with common subframe Using the down control channel of up DCI format in same subframe, therefore, the terminal detects in the subframe m+k , it is necessary to first determine whether the down control channel corresponds to special subframe after to the down control channel using up DCI format The PUSCH of middle transmission, after it is determined that the down control channel corresponds to the PUSCH sent in special subframe, under described What row control channel carried is used to indicate whether the instructions field of re-transmission, it is determined whether retransmits what is sent in the special subframe m PUSCH.Wherein it is determined that the down control channel can use above-mentioned side when whether corresponding to the PUSCH sent in special subframe Either type or combination in formula 1~5.

Based on any of the above-described embodiment, terminal described in S23 is according to the down control channel, it is determined whether described in re-transmission The PUSCH sent in special subframe m, is specifically included：

1st, the terminal is detected in the subframe comprising downlink resource after the special subframe m, further bag Include following two situations：

If 1) terminal is examined in the subframe that any one after the special subframe m includes downlink resource Survey, i.e., without setting time is defined, then the terminal is maintained in the PUSCH sent in the special subframe m related letter Breath, until receiving the down control channel using up DCI format that can determine whether the PUSCH retransmits, i.e., corresponding spy The PUSCH and the down control channel of the up DCI format of use sent in different subframe.Further, according to the down control channel The instructions field for being used to indicate whether to retransmit of middle carrying, it is determined whether retransmit the PUSCH sent in the special subframe m.

If 2) any one of the terminal in the setting time after the special subframe m includes the son of downlink resource Detected in frame, that is, define setting time, then：

Although if the terminal be not detected by setting time using up DCI format down control channel or Detect and correspond to what is sent in common subframe using the down control channel but the down control channel of up DCI format PUSCH, then the PUSCH transmission success that the terminal determination is sent in the special subframe m, it is not necessary to retransmit；

If the terminal detects the down control channel using up DCI format, and the descending control in setting time Channel processed corresponds to the PUSCH sent in special subframe, then the terminal is used to indicate according to what is carried in the down control channel The instructions field whether retransmitted, it is determined whether retransmit the PUSCH sent in the special subframe m.

2nd, the terminal is detected in subframe m+k, further comprises situation：

If 1) terminal detects the down control channel using up DCI format in the subframe m+k, and under this Row control channel corresponds to the PUSCH sent in special subframe, then the terminal is used for according to what is carried in the down control channel Indicate whether the instructions field retransmitted, it is determined whether retransmit the PUSCH sent in the special subframe m.

If 2) terminal is not detected by the down control channel using up DCI format in the subframe m+k, or Correspond to what is sent in common subframe using the down control channel but the down control channel of up DCI format although detecting PUSCH, then the PUSCH transmission success that the terminal determination is sent in the special subframe m, it is not necessary to retransmit.

Optionally, the instructions field for being used to indicate whether to retransmit is NDI, i.e., described terminal is according in the down control channel The NDI of carrying, it is determined whether retransmit the PUSCH sent in the special subframe m.

Specifically, for dynamic dispatching, i.e., transmit each time corresponding to down control channel PUSCH：It is if described NDI in down control channel transmits corresponding NDI relative to the first time of the PUSCH and not changed, then terminal Need to retransmit the PUSCH；If the NDI in the down control channel is relative to corresponding to the first time transmission of the PUSCH NDI changed, i.e., described down control channel scheduled a new PUSCH transmission, then terminal need not retransmit institute State PUSCH.

For semi-continuous scheduling (Semi-Persistent Scheduling, abbreviation SPS) PUSCH：If the descending control NDI in channel processed is 0, represents that the descending control that the down control channel is indicating downlink SPS resource actives/release is believed The traffic order in road, i.e. SPS PUSCH, then terminal need not retransmit the PUSCH；If the NDI in the down control channel For 1, then terminal needs to retransmit the PUSCH.

Certainly, if ACK/NACK feedback informations are NACK, base station is if one want to dynamic dispatching retransmits to change PUSCH-3 Resource and configuration, can also send the down control channel using up DCI format in subframe 6, and by the descending control NDI in channel is set to the NDI identical value (examples in the down control channel corresponding with the transmission of the first time of the PUSCH-3 The NDI as corresponding to first time transmission is 0, then 0) NDI in the down control channel is also set to.

2nd, end side：

1) schedule information of the PUSCH-1 for being transmitted in UpPTS of the dispatch terminal in special subframe 1 is received, and is pressed According to sending the PUSCH-1 in UpPTS of the schedule information in special subframe 1；Being provided comprising downlink transfer after special subframe 1 Any one in the subframe in source or in the setting time after special subframe 1 includes the subframe of downlink resource (such as thereafter Each descending sub frame and/or special subframe in 10 subframes), detection uses the down control channel of up DCI format.

If specifically, defining setting time, if be not detected by setting time, terminal judges that base station is not sent out The down control channel for sending instruction to retransmit, i.e. terminal judge PUSCH-1 transmission success, it is not necessary to retransmit, if being not specified by setting Time, then terminal need to maintain PUSCH-1 information always, can interpolate that what whether the PUSCH-1 retransmitted until receiving DCI makees further operation；If detecting, such as down control channel is detected in subframe 9, then terminal is according to the descending control The PUSCH-1 transmitted in the UpPTS that the process number indicated by the first instructions field in channel is defined as in corresponding special subframe 1, Then the NDI in the down control channel relative to the first time of the PUSCH-1 transmit corresponding NDI whether overturn come Determine the need for retransmitting.If for example, the NDI transmits with first time, corresponding NDI is identical, and terminal determines to need to retransmit, And according to the schedule information (i.e. the information such as indicated resource and modulating-coding grade) in the down control channel to PUSCH-1 Retransmitted；And for example, if the NDI transmits from first time, corresponding NDI is different, and terminal is defined as new data transmission, and root Start to transmit new data according to schedule information, that is, judge PUSCH-1 transmission success, it is not necessary to retransmit.

2) schedule information of the PUSCH-2 for being transmitted in UpPTS of the dispatch terminal in special subframe 6 is received, according to Schedule information sends the PUSCH-2 in the UpPTS in special subframe 6；Downlink transfer resource is included after special subframe 6 Subframe in or any one in the setting time after special subframe 6 include the subframe (such as thereafter 10 of downlink resource Each descending sub frame and/or special subframe in individual subframe), detection uses the down control channel of up DCI format.

If specifically, defining setting time, if be not detected by setting time, terminal judges that base station is not sent out The down control channel for sending instruction to retransmit, i.e. terminal judge PUSCH-2 transmission success, it is not necessary to retransmit, if being not specified by setting Time, then terminal need to maintain PUSCH-2 information always, can interpolate that what whether the PUSCH-2 retransmitted until receiving DCI makees further operation；If detecting, such as down control channel is detected in subframe 9, then terminal is according to the descending control The PUSCH-2 transmitted in the UpPTS that the process number indicated by the first instructions field in channel is defined as in corresponding special subframe 6, Then the NDI in the down control channel relative to the first time of the PUSCH-2 transmit corresponding NDI whether overturn come Determine the need for retransmitting.If for example, the NDI transmits with first time, corresponding NDI is identical, and terminal determines to need to retransmit, And according to the schedule information (i.e. the information such as indicated resource and modulating-coding grade) in the down control channel to PUSCH-2 Retransmitted.And for example, if the NDI transmits from first time, corresponding NDI is different, and terminal is defined as new data transmission, and root Start to transmit new data according to schedule information, that is, judge PUSCH-2 transmission success, it is not necessary to retransmit.

3) PUSCH-3 transmitted for dispatch terminal in generic uplink subframe 2 schedule information is received, is believed according to scheduling Breath sends the PUSCH-3 in sub-frame of uplink 2；According to the k in table 3_PHICHDefinition, determines PUSCH-3 PHICH in subframe 6 Send, and indicated according to the DMRS cyclic shifts in PUSCH-3 minimum PRB index and dispatch, determine that its PHICH is provided Source parameterCarrying PUSCH-3 ACK/NACK feedback informations are detected in subframe 6 according to the parameter PHICH, and the feedback information in the PHICH determines whether to retransmit.Specifically：It need not then be retransmitted if ACK, such as Fruit is that NACK then transmits PUSCH-3 again according to first time transmission identical schedule information.

Certainly, terminal can also detect the down control channel using up DCI format simultaneously in subframe 6, if not Detect, then the feedback information in above-mentioned PHICH is defined, if detected, the NDI in the down control channel is relative Whether overturn in the corresponding NDI of the first time transmission of the PUSCH-3 to determine the need for retransmitting.Specifically：If the NDI with It is identical to transmit corresponding NDI for the first time, then terminal determines to need to retransmit, and according to the schedule information in the down control channel (i.e. the information such as indicated resource and modulating-coding grade) retransmits to PUSCH-3；If the NDI and first time transmission institute are right The NDI that answers is different, then terminal is defined as new data transmission, and is started according to schedule information to transmit new data, that is, judges PUSCH-3 transmission success, it is not necessary to retransmit.

In the present embodiment, if DCI sizes used in the PUSCH transmitted in corresponding UpPTS down control channel with DCI used in the PUSCH transmitted in corresponding generic uplink subframe down control channel is of different sizes, then can also be common The PUSCH transmitted in corresponding UpPTS down control channel is transmitted in PHICH transmission subframes corresponding to sub-frame of uplink, now, Terminal can be distinguished on down control channel is PUSCH in corresponding UpPTS or is common by the different size of DCI of blind check PUSCH in row subframe.If DCI sizes used in the PUSCH transmitted in corresponding UpPTS down control channel with it is corresponding DCI sizes are identical used in the PUSCH transmitted in generic uplink subframe down control channel, then need base station scheduling to realize Avoid that the PUSCH transmitted in UpPTS down control channel will be corresponded to and correspond under the PUSCH transmitted in generic uplink subframe Row control channel is transmitted in same subframe, or is needed under the PUSCH by being transmitted in definition or the corresponding UpPTS of configuration The PUSCH transmitted in row control channel and corresponding generic uplink subframe down control channel is distinguished using different RNTI, Or need to correspond to by defining and transmitted in the PUSCH transmitted in UpPTS down control channel and corresponding generic uplink subframe The PUSCH instruction of the second bit field of down control channel distinguish, wherein, in order to not change in generic uplink subframe Original DCI sizes, the idle bit domain in the DCI can be used to reuse and be used as the second bit field.

1st, base station side：

If ACK/NACK feedback informations are NACK,：Any one of base station after special subframe 1 includes downlink resource Subframe or any one in the setting time after special subframe 1 include the subframe (such as 10 thereafter of downlink resource Any one descending sub frame and/or special subframe in subframe, scheduling realization and resource allocation conditions depending on base station), example Such as in subframe 6, the down control channel using up DCI format is sent to the terminal, and by the down control channel NDI is set to the NDI identical values in the down control channel corresponding with the transmission of the first time of the PUSCH-1, for example, for the first time NDI corresponding to transmission is 0, then the NDI in the down control channel is also set to 0.Further base station can use it is following either one Method is handled the down control channel：

Method A：The down control channel is transmitted using the first DCI sizes, the first DCI is of different sizes in generic uplink DCI sizes corresponding to subframe；

Method B：The second instructions field in the down control channel is set to " 1 ", represents that the down control channel is corresponding The PUSCH transmitted in UpPTS；

Method C：The down control channel is scrambled using the first RNTI, it is right that the first RNTI is different from generic uplink subframe institute The RNTI answered, for distinguishing the down control channel of the PUSCH in corresponding generic uplink subframe.

2) dispatch terminal transmits PUSCH-2 in generic uplink subframe 2；Receiving terminal is sent in sub-frame of uplink 2 PUSCH-2, and obtain the ACK/NACK feedback informations of its 1 bit；According to the k in table 3_PHICHDefinition, determines PUSCH-2's PHICH is sent in subframe 6, and is referred to according to the DMRS cyclic shifts in PUSCH-2 minimum PRB index and dispatch Show, determine its PHICH resource parameterSend carrying PUSCH-2's in subframe 6 according to the parameter The PHICH of ACK/NACK feedback informations.

Certainly, if ACK/NACK feedback informations are NACK, base station is if one want to dynamic dispatching is heavy to change PUSCH-2 The resource of biography and configuration, can also send the down control channel using up DCI format in subframe 6, and by the descending control NDI in channel processed is set to the NDI identical values in the down control channel corresponding with the transmission of the first time of the PUSCH-2, For example, NDI corresponding to transmission is 0 for the first time, then the NDI in the down control channel is also set to 0.Further base station can use Following either method is handled the down control channel：

Method 1：The down control channel is transmitted using the 2nd DCI sizes, the 2nd DCI sizes are generic uplink subframe Corresponding DCI sizes；

Method 2：The second instructions field in the down control channel is set to " 0 ", it is general to represent that the down control channel corresponds to The PUSCH transmitted in logical sub-frame of uplink；

Method 3：The down control channel is scrambled using the 2nd RNTI, for distinguishing the descending of the PUSCH in corresponding UpPTS Control channel；

2nd, end side：

1) schedule information of the PUSCH-1 for being transmitted in UpPTS of the dispatch terminal in special subframe 1 is received, according to Schedule information sends the PUSCH-1 in the UpPTS in special subframe 1；Downlink transfer resource is included after special subframe 1 Subframe in or any one in the setting time after special subframe 1 include the subframe (such as thereafter 10 of downlink resource Each descending sub frame and/or special subframe in individual subframe), detection uses the down control channel of up DCI format.It is if fixed Justice setting time, then if being not detected by the down control channel using up DCI format in setting time, then terminal is sentenced Disconnected base station does not send the down control channel that instruction retransmits, that is, judges the PUSCH-1 transmission success, it is not necessary to retransmit, if do not had Have an agreement setting time, then terminal is needed to maintain PUSCH-1 information always, and the PUSCH-1 is can interpolate that until receiving The DCI whether retransmitted makees further operation；If the down control channel using up DCI format is detected, such as in subframe 6 In detect down control channel, then terminal is handled using method corresponding with base station side：

Method A：If the DCI sizes detected be the first DCI sizes (i.e. by the DCI of blind check the first and the 2nd DCI sizes, It is the down control channel using the first DCI sizes that the down control channel, which is determined), determine that the down control channel is corresponding PUSCH in UpPTS；

Method B：If the second instructions field in the down control channel is " 1 ", determine that the down control channel corresponds to UpPTS In PUSCH；

Method C：If the down control channel using the first RNTI scramblings (i.e. by the RNTI of blind check the first and the 2nd RNTI, Determine the down control channel for the first RNTI scramblings), determine that the down control channel corresponds to the PUSCH in UpPTS.

Further, NDI of the terminal in the down control channel is relative to corresponding to the first time transmission of the PUSCH-1 NDI whether overturn to determine the need for retransmitting.For example, the NDI and first time, to transmit corresponding NDI identical, then terminal It is determined that need to retransmit, and according to schedule information (the i.e. indicated resource and modulating-coding grade etc. in the down control channel Information) PUSCH-1 is retransmitted；And for example, the NDI is different from the NDI that first time transmission is corresponding, then terminal is defined as new number According to transmission, and started according to schedule information to transmit new data, that is, judge PUSCH-1 transmission success, it is not necessary to retransmit.

2) PUSCH-2 transmitted for dispatch terminal in generic uplink subframe 2 schedule information is received, is believed according to scheduling Breath sends the PUSCH-2 in sub-frame of uplink 2；According to the k in table 3_PHICHDefinition, determines PUSCH-2 PHICH in subframe 6 Send, and indicated according to the DMRS cyclic shifts in PUSCH-2 minimum PRB index and dispatch, determine that its PHICH is provided Source parameterCarrying PUSCH-2 ACK/NACK feedback informations are detected in subframe 6 according to the parameter PHICH, and the feedback information in the PHICH determines whether to retransmit.If ACK/NACK feedback informations are ACK, eventually End determination need not retransmit；If ACK/NACK feedback informations are NACK, terminal is according to first time transmission identical scheduling letter Breath transmits PUSCH-2 again.Certainly, terminal can also simultaneously be detected in subframe 6 and believed using the descending control of up DCI format Road, if be not detected by, the feedback information in above-mentioned PHICH is defined, if it is detected terminal uses and base station side pair The method answered is handled：

Method 1：It is that the 2nd DCI sizes are (big i.e. by the DCI of blind check the first and the 2nd DCI according to the DCI sizes detected It is small, it is determined that the down control channel is the DCI format using the 2nd DCI sizes), it is common to determine that the down control channel corresponds to PUSCH in sub-frame of uplink；

Method 2：The second instructions field in the down control channel is " 0 ", and it is general to determine that the down control channel corresponds to PUSCH in logical sub-frame of uplink；

Method 3：The RNTI of blind check the first and second (is passed through using the 2nd RNTI scramblings according to the down control channel RNTI, it is determined that the down control channel is the 2nd RNTI scramblings), determine that the down control channel corresponds to generic uplink subframe In PUSCH.

Further, NDI of the terminal in the down control channel is relative to corresponding to the first time transmission of the PUSCH-2 NDI whether overturn to determine the need for retransmitting.For example, the NDI and first time, to transmit corresponding NDI identical, then terminal It is determined that need to retransmit, and according to schedule information (the i.e. indicated resource and modulating-coding grade etc. in the down control channel Information) PUSCH-2 is retransmitted；And for example, the NDI is different from the NDI that first time transmission is corresponding, then terminal is defined as new number According to transmission, and started according to schedule information to transmit new data, that is, judge PUSCH-2 transmission success, it is not necessary to retransmit.

Embodiment 3：The present embodiment transmits still by taking TDD uplink-downlink configurations 1 as an example in the UpPTS in special subframe 1 or 6 PUSCH assume use synchronous HARQ, the PUSCH transmitted in special subframe m ACK/NACK feedback informations are in subframe m+k Obtained by detecting the down control channel of loading ACK/NACK feedback informations, where it is assumed that k=4.Separately below from base station The implementation of side and end side is described.

1st, base station side：

If ACK/NACK feedback informations are ACK,：If base station does not have new transmitting uplink data to need to dispatch, it is not required to The down control channel using up DCI format is sent to the terminal；If base station has new transmitting uplink data to need to adjust Degree, the NDI NDI transmitted relative to PUSCH-1 first time in corresponding down control channel are overturn and (are set to not Same value, such as NDI corresponding to transmission is 0 for the first time, then 1) NDI in the down control channel is set to, and in the (root of subframe 5 Obtained according to m+k) in the terminal send carry the NDI down control channel；

If ACK/NACK feedback informations are NACK, base station sends to the terminal in subframe 5 (being obtained according to m+k) and used The down control channel of up DCI format, and the NDI in the down control channel is set to and passed with the first time of the PUSCH-1 NDI identical values in defeated corresponding down control channel, for example, NDI corresponding to transmission is 0 for the first time, then the descending control NDI in channel processed is also set to 0.

Certainly, if ACK/NACK feedback informations are NACK, base station is if one want to dynamic dispatching is heavy to change PUSCH-2 The resource of biography and configuration, can also send the down control channel using up DCI format in subframe 6, and by the descending control NDI in channel processed is set to the NDI identical values in the down control channel corresponding with the transmission of the first time of the PUSCH-2, For example, NDI corresponding to transmission is 0 for the first time, then the NDI in the down control channel is also set to 0.

It should be noted that because the feedback subframe position of definition is different, it is above-mentioned sent in subframe 5 and subframe 6 hold Carrying the down control channel of ACK/NACK feedback informations can use identical DCI and identical RNTI to scramble, and terminal can be with Judge that the PUSCH corresponding to the down control channel corresponds to UpPTS or general by detecting the subframe of down control channel Logical sub-frame of uplink.

2nd, end side：

1) schedule information of the PUSCH-1 for being transmitted in UpPTS of the dispatch terminal in special subframe 1 is received, according to Schedule information sends the PUSCH-1 in the UpPTS in special subframe 1；According to m+k, it is determined that being detected in subframe 5 using up The down control channel of DCI format.

If specifically, being not detected by, terminal judges that base station does not send the down control channel that instruction retransmits, that is, judges The PUSCH-1 transmission success, it is not necessary to retransmit；

If it is detected NDI of the terminal in the down control channel transmits relative to the first time of the PUSCH-1 Whether corresponding NDI is overturn to determine the need for retransmitting.If for example, the NDI transmits corresponding NDI phases with first time Together, then terminal is determined to need to retransmit, and (i.e. indicated resource and modulation is compiled according to the schedule information in the down control channel The information such as code grade) PUSCH-1 is retransmitted；And for example, if the NDI is different from the NDI that first time transmission is corresponding, terminal It is defined as new data transmission, and is started according to schedule information to transmit new data, that is, judges PUSCH-1 transmission success, it is not necessary to Retransmit.

2) PUSCH-2 transmitted for dispatch terminal in generic uplink subframe 2 schedule information is received, is believed according to scheduling Breath sends the PUSCH-2 in sub-frame of uplink 2；According to the k in table 3_PHICHDefinition, determines PUSCH-2 PHICH in subframe 6 Send, and indicated according to the DMRS cyclic shifts in PUSCH-2 minimum PRB index and dispatch, determine that its PHICH is provided Source parameterCarrying PUSCH-2 ACK/NACK feedback informations are detected in subframe 6 according to the parameter PHICH, and the ACK/NACK feedback informations in the PHICH determine whether to retransmit.If ACK/NACK feedback informations are ACK, Then terminal channel need not retransmit；If ACK/NACK is NACK, terminal transmits identical schedule information again according to first time Transmit PUSCH-2.

Certainly, terminal can also detect the down control channel using up DCI format simultaneously in subframe 6；If not Detect, then the feedback information in above-mentioned PHICH is defined；If it is detected the NDI phases in the down control channel Whether the corresponding NDI of the first time transmission for the PUSCH-2 is overturn to determine the need for retransmitting.If for example, the NDI with It is identical to transmit corresponding NDI for the first time, then terminal determines to need to retransmit, and according to the schedule information in the down control channel (i.e. the information such as indicated resource and modulating-coding grade) retransmits to PUSCH-2；And for example, if the NDI with passing for the first time Defeated corresponding NDI is different, then terminal is defined as new data transmission, and is started according to schedule information to transmit new data, that is, sentences Disconnected PUSCH-2 transmission success, it is not necessary to retransmit.

It is to be illustrated by taking the PUSCH of dynamic dispatching as an example in above-described embodiment, side provided in an embodiment of the present invention Method is equally applicable for SPS PUSCH, only difference is that, if SPS PUSCH, NDI definition are not upsets, and It is that 1 expression retransmits, 0 represents just to pass, and remaining processing is identical with the PUSCH of dynamic dispatching, no longer illustrates one by one herein.

In above-described embodiment 1 and 2, so that the PUSCH in UpPTS uses asynchronous HARQ as an example, the PUSCH in UpPTS is made It is equally applicable with synchronous HARQ；If synchronous HARQ, process is similar, the only difference is that in the corresponding UpPTS of base station side transmission The PUSCH subframe of down control channel be not any subframe after special subframe or the setting time after special subframe Interior any subframe, but the fixation subframe position determined according to UpPTS subframe number and table 7, and end side is being detected During the down control channel of the PUSCH in corresponding UpPTS, nor each subframe detection after UpPTS or Each subframe detection in setting time after UpPTS, but the stator of subframe number and table 7 determination in UpPTS Frame position detects.

Above method handling process can realize that the software program can be stored in storage medium with software program, when When the software program of storage is called, above method step is performed.
