Wireless base station and travelling carriage

The application is that the original bill application number is the dividing an application of application for a patent for invention (international application no: PCT/JP2007/065786, the applying date: on August 10th, 2007, denomination of invention: wireless base station and travelling carriage) of No.200780100011.5.

Technical field

The present invention relates to wireless base station and travelling carriage, relate in particular to wireless base station and travelling carriage that error detection result's the information of expression downlink data is received and dispatched.

Background technology

The wireless base station is when sending downlink data, in down control channel (PDCCH:Physical DownlinkControl Channel, Physical Downlink Control Channel), will send the down dispatch informations such as the information of radio resource allocation of downlink data and transformat and send to travelling carriage as the transmission destination of this downlink data.Then, the wireless base station is according to specified down dispatch information, carry out the coding, modulation of downlink data, to mapping of Radio Resource etc., in downstream data channel (PSDCH:Physical Downlink Shared Channel, Physical Downlink Shared Channel), send.Travelling carriage is from a plurality of PDCCH(candidates) detection whether exist and send to the PDCCH that controls oneself, when detecting when sending to the PDCCH that controls oneself, this PDCCH is decoded, according to the down dispatch information that wherein comprises, receive PDSCH, downlink data receiving.

Figure 26 is the figure that PDCCH and PDSCH are shown.Show in the drawings the subframe of 1ms.The longitudinal direction of figure represents frequency, and transverse direction represents the time.

As shown in the figure, in frequency-domain and time-domain, distribute control channel (PDCCH) i, j, k and data channel (PDSCH) i, j, k.Here, the control channel of supposing to send to certain travelling carriage is control channel j.In this case, certain travelling carriage receives the control channel j that sends to oneself, according to the control channel j that receives, and the data of receive data channel j.

Travelling carriage detects the PDCCH that sends to oneself, and downlink data receiving.Then, travelling carriage carries out the error detection of downlink data.If travelling carriage does not detect the mistake of downlink data, then return ACK(ACKnowledgement to the wireless base station, positive acknowledgement), if the mistake of detecting then sends NACK(Negative ACK, Negative Acknowledgement to the wireless base station).The wireless base station sends next data when receiving ACK, when receiving NACK, retransmit the previous data that send.

Figure 27 is transmission that downlink data is shown and the figure of the response relative with it.In the drawings, show the wireless base station and send to the downlink data of travelling carriage and the ACK/NACK that travelling carriage sends to the wireless base station.

As shown in the figure, the wireless base station sends downlink data to travelling carriage.Travelling carriage carries out error detection to the downlink data that receives, if do not detect mistake, then sends ACK to the wireless base station.On the other hand, when detecting the data that receive when wrong, as shown in the figure, send NACK to the wireless base station.At this moment, as shown in the figure, the previous downlink data that sends is retransmitted in the wireless base station.

When travelling carriage sends upstream data, the wireless base station will send to the travelling carriage that will send upstream data for the ascending wireless resource assignment information (UL allocation grant, uplink assignment mandate) that upstream data sends in PDCCH.Travelling carriage uses the Radio Resource by the wireless base station appointment to send upstream data.Travelling carriage if there is the ACK/NACK that receives for downlink data, then uses a part of distributing to the Radio Resource that upstream data sends when sending upstream data, carry out sending after multiplexing with upstream data.

Figure 28 is the figure that ascending wireless resource assignment information and the upstream data relative with it are shown.There is shown the wireless base station and send to the ascending wireless resource assignment information of travelling carriage and the upstream data that travelling carriage sends to the base station.

The wireless base station sends to travelling carriage with ascending wireless resource assignment information as shown in the figure in PDCCH.Travelling carriage sends upstream data according to the ascending wireless resource assignment information from the wireless base station.

Transmission is divided into for the method for the ACK/NACK information of downlink data: these 2 kinds of the situations that travelling carriage sends the situation of upstream data and do not send upstream data.At first, the situation that does not send upstream data is described.

Figure 29 is the figure that the ACK/NACK sending method when not sending upstream data describes.Among the figure, show the ascending control channel (PUCCH:Physical Uplink ControlChannel, Physical Uplink Control Channel) that sends from travelling carriage to the wireless base station.Travelling carriage is in the situation that send upstream data, in pre-assigned (or being associated with the Radio Resource that sends downlink data) PUCCH, sends ACK/NACK.And as shown in the figure, the frequency of (0.5ms) variation PUCCHi, PUCCHj is in order to obtain the frequency diversity effect take time slot as unit.

Then, the situation that sends upstream data is described.

Figure 30 is the figure that the ACK/NACK sending method when sending upstream data describes.Among the figure, show by the UL allocation grant on the PDCCH(PDCCH) uplink data channels (PUSCH:PhysicalUplink Shared Channel, Physical Uplink Shared Channel) that distributes.

When having PUSCH, as shown in the figure, travelling carriage sends to wireless base station (for example, with reference to non-patent literature 1) after ACK/NACK and upstream data are carried out time division multiplexing.

Non-patent literature 1:R1-073128, " HARQ symbol to RE mapping ", 3GPP TSG RAN WG1Meeting#49bis, Orlando, FL, USA, June 25-29,2007

But, in above-mentioned ACK/NACK sending method, there is following problems, that is: between the upstream data form of the desired upstream data form in wireless base station and the actual transmission of travelling carriage, produces inconsistently, occur in the situation that can not correctly receive upstream data in the wireless base station.

Figure 31 is the inconsistent figure of specification format (its 1).There is shown the down dispatch information 301, ascending wireless resource assignment information 302 and the downlink data 303 that send to travelling carriage from the wireless base station.In addition, show the upstream data 304 that sends to the wireless base station from travelling carriage.Respectively down dispatch information 301 and ascending wireless resource assignment information 302 have been carried out error correction coding.

In Figure 31, suppose travelling carriage to the detection failure of down dispatch information 301, to the detection success of ascending wireless resource assignment information 302.In this case, since failed to the detection of down dispatch information 301, so travelling carriage does not carry out the reception ﹠ disposal of downlink data 303.On the other hand, since successful to the detection of ascending wireless resource assignment information 302, so travelling carriage sends to the wireless base station with upstream data 304 as shown in the figure.

Because travelling carriage does not carry out the reception ﹠ disposal of downlink data 303, therefore do not carry out the error detection of downlink data 303.Thereby travelling carriage does not carry out ACK/NACK and upstream data 304 multiplexing as shown in Figure, only upstream data 304 is sent to the wireless base station.

Figure 32 is the inconsistent figure of specification format (its 2).In Figure 32, to the content mark identical label identical with Figure 31, the description thereof will be omitted.

In Figure 32, suppose that travelling carriage is to the detection success of down dispatch information 301 and ascending wireless resource assignment information 302.In this case, because travelling carriage downlink data receiving 303, therefore carry out the error detection of downlink data 303, ACK/NACK 305 and upstream data 304 are carried out sending to the wireless base station after multiplexing.

Shown in the upstream data 304 and ACK/NACK 305 of the upstream data 304 of Figure 31, Figure 32, ACK/NACK and upstream data is multiplexing and when sending to the wireless base station, generation is inconsistent between the PUSCH transformat of wireless base station prediction and the actual PUSCH transformat that sends of travelling carriage.

Namely, when sending downlink data from the wireless base station, if travelling carriage is failed to the detection of down dispatch information, successful to the detection of ascending wireless resource assignment information, although then originally must send upstream data behind the multiplexing ACK/NACK, but only send upstream data, in the wireless base station, can not correctly receive upstream data.

Embodiment

Below, ginseng figure accompanying drawing describes principle of the present invention in detail.

Fig. 1 is the figure that the summary of wireless base station is shown.As shown in the figure, wireless base station 1 has error detection coding handling part 1a and sending part 1b.Travelling carriage 2 is received the 1st required control data of downstream signal in wireless base station 1 and the 2nd required control data of travelling carriage 2 transmission upstream datas send to travelling carriage 2.The 1st control data for example are the down dispatch informations that sends in PDCCH, and the 2nd control data for example are the ascending wireless resource assignment information that sends in PDCCH.

Error detection coding handling part 1a carries out error detection coding and processes to comprise the 1st control data and the 2nd data of controlling the data both sides as unit.That is, error detection coding handling part 1a does not carry out the error detection coding processing to the 1st control data and the 2nd control data separately, processes but carry out in the lump error detection coding.

Sending part 1b will send to travelling carriage 2 by the 1st control data and the 2nd control data that error detection coding handling part 1a carries out after error detection coding is processed.

Like this, wireless base station 1 carries out error detection coding and processes to comprise the 1st control data and the 2nd data of controlling the data both sides as unit.Thereby travelling carriage 2 can only not carry out error detection to the side in the 1st control data and the 2nd control data, thereby the situation of 1 control data receiver success can not occur only having.For example, if the 1st control data are wrong, then because travelling carriage carries out error detection as a whole with the 1st control data and the 2nd control data, thereby the detection failure of the 2nd control data.

Thus, following situation can not occur, i.e. taking defeat of 2 pairs the 1st control of travelling carriage data to the reception success of the 2nd control data, sends to wireless base station 1 according to the 2nd control data with upward signal.That is, after data received successfully, just transmission comprised the error detection result's of downstream signal upward signal to travelling carriage 2, therefore, the inconsistent situation of form of the receive data of wireless base station 1 can not occur in the 1st control data and the 2nd control.Thereby wireless base station 1 can correctly receive upward signal.

Then, with reference to accompanying drawing, describe the 1st execution mode of the present invention in detail.

Fig. 2 is the figure of topology example that the wireless system of the 1st execution mode is shown.There is shown wireless base station 11 and travelling carriage 12.Wireless base station 11 shown in the figure and travelling carriage 12 carry out for example based on LTE(Long TermEvolution, Long Term Evolution) radio communication.

The 11 pairs of down dispatch informations in wireless base station and ascending wireless resource assignment information are encoded in the lump, send in PDCCH.

12 couples of PDCCH that send to oneself of travelling carriage detect.When comprising down dispatch information and ascending wireless resource assignment information in successfully detecting the PDCCH that sends to oneself and the PDCCH that detects, travelling carriage 12 carries out the reception ﹠ disposal of downlink data, and downlink data is carried out error detection.Then, in the PUSCH based on the ascending wireless resource assignment information, with upstream data with the ACK/NACK corresponding with the error detection result of downlink data is multiplexing and send.On the other hand, when the descending PDCCH that sends to oneself detected unsuccessfully, travelling carriage 12 did not send any information in PUSCH.

Down dispatch information and ascending wireless resource assignment information are encoded in the lump, send to travelling carriage.Thereby, 12 pairs of information of travelling carriage can not occur and detect successfully, another information is detected failed situation.That is, travelling carriage 12 can only not send to wireless base station 11 with upstream data 304 as shown in Figure 31, thereby can not receive the inconsistent situation of form in wireless base station 11.

Fig. 3 is the figure that the action of the wireless base station in detection when success of PDCCH and travelling carriage is shown.There is shown control information 21 and downlink data 22.In addition, show upstream data 23 and carry out time-multiplexed ACK/NACK 24 with upstream data.

Control information 21 is that down dispatch information and ascending wireless resource assignment information are encoded and the information that obtains in the lump.Wireless base station 11 sends this control information 21 in PDCCH.In addition, wireless base station 11 sends downlink data 22 in PDSCH.

Travelling carriage 12 successfully detects control information 21, according to the down dispatch information of control information 21, and downlink data receiving 22.12 pairs of downlink datas that receive of travelling carriage 22 carry out error detection.In addition, travelling carriage 12 sends to wireless base station 11 according to the ascending wireless resource assignment information with upstream data 23.Travelling carriage 12 will carry out as the error detection result's of downlink data 22 ACK/NACK 24 and upstream data 23 multiplexing, and send to wireless base station 11.

Fig. 4 is the figure that the action of the wireless base station in detection when failure of PDCCH and travelling carriage is shown.In Fig. 4, to the content mark identical label identical with Fig. 3, the description thereof will be omitted.

The control information 21 that wireless base station 11 obtains after sending in PDCCH down dispatch information and ascending wireless resource assignment information being encoded in the lump.In addition, wireless base station 11 sends downlink data 22 in PDSCH.

Suppose that 12 pairs of travelling carriages comprise the detection failure of the control information 21 of down dispatch information and ascending wireless resource assignment information.In this case, travelling carriage 12 can't detect down dispatch information, thereby does not carry out the reception ﹠ disposal of downlink data 22.In addition, also can't detect the ascending resource assignment information, thereby also not carry out the transmission processing of upstream data.

Although wireless base station 11 has sent downlink data 22 in PDSCH, do not receive any information from travelling carriage 12.Therefore, wireless base station 11 detects the DTX that expression does not send ack/nack signal.When detecting DTX, shown in control information 25 and downlink data 26 among the figure, the downlink data 22 that wireless base station 11 will before send resends to travelling carriage 12.

When detecting the data of repeating transmission, identical with content illustrated in fig. 3, travelling carriage 12 sends to wireless base station 11 with upstream data 23 and ACK/NACK 24.

Among Figure 31, Figure 32, down dispatch information 301 and ascending wireless resource assignment information 302 are encoded individually.Therefore, occured to only have one in the down dispatch information 301 that comprises among the PDCCH and the ascending wireless resource assignment information 302 to detect unsuccessfully the phenomenon of another detection success.Thus, between the transformat of the transformat of wireless base station and travelling carriage, produced inconsistent.

Relative therewith, such as shown in Figure 3, Figure 4, the 11 pairs of down dispatch informations in the wireless base station of Fig. 2 and ascending wireless resource assignment information are encoded in the lump.Therefore, can not only have an information to detect unsuccessfully at travelling carriage 12 places, the phenomenon of the detection success of another information is not if the detection failure of 12 pairs of down dispatch informations of encoding in the lump of travelling carriage and ascending wireless resource assignment information then sends upstream data.

Namely, the travelling carriage 12 of Fig. 2 can not send the upstream data of different-format, namely ACK/NACK is carried out the upstream data after multiplexing and ACK/NACK do not carried out multiplexing upstream data, but send all the time ACK/NACK is carried out the upstream data after multiplexing or do not send any data.Thus, be unified from the form of travelling carriage 12, wireless base station 11 can be from travelling carriage 12 receive data correctly.

Fig. 5 is the figure that explanation is encoded to down dispatch information and ascending wireless resource assignment information.There is shown down dispatch information 31 and ascending wireless resource assignment information 32.

As shown in the figure, the 11 pairs of down dispatch informations 31 in wireless base station and ascending wireless resource assignment information 32 in the lump (as data) carry out error detection coding.For example, carry out CRC(Cyclic Redundancy Check, cyclic redundancy check (CRC)) coding.Wireless base station 11 also carries out error correction coding (FEC:Forward Error Correction, forward error correction).For example, carry out Turbo coding or convolutional encoding.

Like this, the 11 pairs of down dispatch informations 31 in wireless base station and ascending wireless resource assignment information 32 are carried out error detection coding in the lump.Thus, travelling carriage 12 can only not carry out error detection to an information.That is, a side in down dispatch information 31 and ascending wireless resource assignment information 32 exists when wrong, and travelling carriage 12 will detect down dispatch information 31 and ascending wireless resource assignment information 32, and both are wrong.

Fig. 6 is the functional block diagram of wireless base station.As shown in the figure, wireless base station 11 has control part 41 and data processing division 42.The data that 41 pairs of data handling parts 42 of control part carry out are processed and are controlled.

Receiving and transmitting part 42j via antenna will from the signal wireless of transmitted signal handling part 42i output send to travelling carriage 12.In addition, receiving and transmitting part 42j receives the signal from travelling carriage 12 wireless transmissions, outputs to receive signal processing part 42k.

Receive signal processing part 42k the received wireless signal of receiving and transmitting part 42j is carried out demodulation or the mapping of resource solution etc.

Lsb decoder 42l decodes to the signal of exporting from reception signal processing part 42k, and ack/nack signal is decoded.

It is ACK or NACK that ACK/NACK detection unit 42m judges by lsb decoder 42 decoded signals.When ACK/NACK detection unit 42m is judged to be NACK, downlink data is controlled with control data generating unit 42a and downlink data generating unit 42f, to retransmit downlink data.

The 42n of error correction decoding section is to carrying out error correction decoding from the upstream data that receives signal processing part 42k output.

Like this, the 11 pairs of down dispatch informations in wireless base station and ascending wireless resource assignment information are encoded in the lump.Thus, send the upstream data of uniform format from travelling carriage 12, wireless base station 11 can correctly receive upstream data.

Then, the 2nd execution mode that present invention will be described in detail with reference to the accompanying.In the 1st execution mode, the wireless base station carries out error correction coding after down dispatch information and ascending wireless resource assignment information are carried out error detection coding in the lump.In the 2nd execution mode, the wireless base station carries out error correction coding in the lump after down dispatch information and ascending wireless resource assignment information are carried out error detection coding respectively.

Fig. 8 is the figure that explanation is encoded to down dispatch information and the ascending wireless resource assignment information of the 2nd execution mode.There is shown down dispatch information 61 and ascending wireless resource assignment information 62.

As shown in the figure, the wireless base station carries out respectively error detection coding to down dispatch information 61 and ascending wireless resource assignment information 62.For example, carry out the CRC coding.

In addition, down dispatch information 61 and the ascending wireless resource assignment information 62 of wireless base station after to error detection coding carried out error correction coding in the lump.For example, carry out Turbo coding or convolutional encoding.

Like this, down dispatch information 61 and ascending wireless resource assignment information 62 are carried out respectively error detection coding, then they are carried out error correction coding in the lump, thus, reduced travelling carriage only carries out error detection to a side information situation.That is, when can not be correctly down dispatch information 61 and ascending wireless resource assignment information 62 being carried out error correction decoding, travelling carriage detects down dispatch information 61 and ascending wireless resource assignment information 62, and both are wrong.

Thus, can reduce travelling carriage failed, successful to the detection of ascending wireless resource assignment information to the detection of down dispatch information, and only upstream data be sent to the situation of wireless base station, and the upstream data form that suppresses in the wireless base station is inconsistent.

Fig. 9 is the functional block diagram of wireless base station.The each several part of Fig. 9 has the function identical with the each several part of base station shown in Figure 6 11.But the wireless base station of Fig. 9 is with respect to the wireless base station of Fig. 6, and the process of coding is different.Below, only the part different from Fig. 6 described.

Relative with the wireless base station 11 of Fig. 6, in the wireless base station of Fig. 9, to respectively carrying out error detection coding with the down dispatch information of control data generating unit 72a output with from upstream data with the ascending wireless resource assignment information of control data generating unit 72c output from downlink data, undertaken multiplexing by multiplexing unit 72e by the 72b of error detection coding section, 72d.Then, by the 72f of error correction coding section the down dispatch information after multiplexing and ascending wireless resource assignment information are carried out error correction coding in the lump.

Figure 10 is the functional block diagram of travelling carriage.The each several part of Figure 10 has the function identical with the each several part of travelling carriage shown in Figure 7 12.But the travelling carriage of Figure 10 is with respect to the travelling carriage of Fig. 7, and the process of decoding is different.Below, only the part different from Fig. 7 described.

The signal that the travelling carriage of Figure 10 receives is after down dispatch information and ascending wireless resource assignment information are carried out error detection coding respectively, to carry out in the lump error correction coding and obtain.Thereby, relative with the travelling carriage 12 of Fig. 7, in the travelling carriage of Figure 10, by the 82c of error correction decoding section the down dispatch information and the ascending wireless resource assignment information that receive are carried out error correction decoding.

In addition, the travelling carriage of Figure 10 is separated into respectively down dispatch information and ascending wireless resource assignment information by down dispatch information and the ascending wireless resource assignment information of separation unit 82d after with error correction.Then, by error detection lsb decoder 82e, 82g the down dispatch information separately after separating and ascending wireless resource assignment information are carried out the error detection decoding.

Like this, the wireless base station carries out error correction coding after down dispatch information and ascending wireless resource assignment information are carried out error detection coding respectively in the lump.Thus, can send from travelling carriage the upstream data of consolidation form, thereby the wireless base station can correctly receive upstream data.

Then, at length the 3rd execution mode of the present invention is described with reference to accompanying drawing.Relative with the 2nd execution mode, in the 3rd execution mode, down dispatch information and ascending wireless resource assignment information are carried out respectively interweaving behind the error detection coding, then carry out in the lump error correction coding.

Figure 11 is the figure that down dispatch information and ascending wireless resource assignment information are encoded of explanation the 3rd execution mode.There is shown down dispatch information 91 and ascending wireless resource assignment information 92.

As shown in the figure, the wireless base station carries out respectively error detection coding to down dispatch information 91 and ascending wireless resource assignment information 92.For example, carry out the CRC coding.In addition, down dispatch information 91 and the ascending wireless resource assignment information 92 of wireless base station after to error detection coding interweaves in the lump.Then, down dispatch information 91 and ascending wireless resource assignment information 92 after 11 pairs of wireless base stations interweave are carried out error correction coding in the lump.For example, carry out Turbo coding or convolutional encoding.

Like this, down dispatch information 91 and ascending wireless resource assignment information 92 are carried out respectively interweaving in the lump behind the error detection coding, in the lump they are carried out error correction coding, also can reduce thus the situation that travelling carriage only carries out error detection to a side information.That is, when can not be correctly down dispatch information 91 and ascending wireless resource assignment information 92 being carried out error correction decoding, travelling carriage will detect down dispatch information 91 and ascending wireless resource assignment information 92 both sides' mistake.

Thus, can reduce travelling carriage failed, successful to the detection of ascending wireless resource assignment information 92 to the detection of down dispatch information 91, and only upstream data be sent to the situation of wireless base station, and the upstream data form in the inhibition base station is inconsistent.

Figure 12 is the functional block diagram of wireless base station.The each several part of Figure 12 has the function identical with the each several part of wireless base station shown in Figure 9.But the wireless base station of Figure 12 is with respect to the wireless base station of Fig. 9, and difference is to interweave.Below, only the part different from Fig. 9 described.

Relative with the wireless base station of Fig. 9, in the wireless base station of Figure 12, by multiplexing unit 102e after to error detection coding down dispatch information and the ascending wireless resource assignment information carry out multiplexing after, the 102f of section interweaves to the data after multiplexing by interweaving.Then, by the 102g of error correction coding section the data after interweaving are carried out error correction coding.

Figure 13 is the functional block diagram of travelling carriage.The each several part of Figure 13 has the function identical with the each several part of travelling carriage shown in Figure 10.But the travelling carriage of Figure 13 is with respect to the travelling carriage of Figure 10, and difference is to interweave.Below, only the part different from Figure 10 described.

The signal that the travelling carriage of Figure 13 receives is that down dispatch information and ascending wireless resource assignment information are carried out respectively error detection coding, then interweaves and error correction coding obtains.Thereby relative with the travelling carriage of Figure 10, in the travelling carriage of Figure 13, the 112d of deinterleaving section carries out deinterleaving to down dispatch information and the ascending wireless resource assignment information of being undertaken by the 112c of error correction decoding section behind the error correction decoding.

In addition, the travelling carriage of Figure 13 separates respectively with the ascending wireless resource assignment information by the down dispatch information of separation unit 112e after with deinterleaving.Then, by error detection lsb decoder 112f, 112h the down dispatch information after separating and ascending wireless resource assignment information are carried out respectively the error detection decoding.

Like this, the wireless base station interweaves after down dispatch information and ascending wireless resource assignment information are carried out error detection coding respectively.Then, the down dispatch information after interweaving and ascending wireless resource assignment information are carried out error correction coding in the lump.Thus, also can send from travelling carriage the upward signal of uniform format, thereby the wireless base station can correctly receive upstream data.

Then, the 4th execution mode that present invention will be described in detail with reference to the accompanying.In the 4th execution mode, no matter have or not the downlink data that sends to oneself, travelling carriage is all guaranteed the zone that ACK/NACK uses in PUSCH.Then, when receiving the downlink data that sends to oneself, ACK or NACK are multiplexed in this zone, (when not detecting the down dispatch information that sends to oneself) sends NACK in this zone when not receiving the downlink data that sends to oneself.

Figure 14 is the figure that the action of the wireless base station of the 4th execution mode and travelling carriage is shown.There is shown down dispatch information 121,126 and ascending wireless resource assignment information 122,127 and downlink data 123,128.In addition, show upstream data 124,129 and the ACK/NACK zone 125,130 of in PUSCH, guaranteeing.And, respectively to down dispatch information 121,126 and ascending wireless resource assignment information 122,127 carry out sending to travelling carriage after error detection coding and the error correction coding.

Suppose that travelling carriage detects successfully down dispatch information 121.Travelling carriage is according to down dispatch information 121, downlink data receiving 123.

In addition, suppose that travelling carriage is to the detection success of ascending resource assignment information 122.Travelling carriage sends to the wireless base station according to ascending wireless resource assignment information 122 with upstream data 124.At this moment, travelling carriage is guaranteed the zone 125 for storage ACK/NACK in PUSCH, sends to the wireless base station after being stored in ACK/NACK in this zone 125.

For example, after detecting the downlink data 123 that receives when wrong, be stored in ACK in the zone 125, travelling carriage do not send to the wireless base station.When detecting the downlink data 123 that receives when wrong, travelling carriage sends to the wireless base station after being stored in NACK in the zone 125.The wireless base station receives ACK/NACK from zone 125, judge accordingly the repeating transmission of downlink data.

Suppose that travelling carriage is to the detection failure of down dispatch information 126.At this moment, travelling carriage does not carry out the reception ﹠ disposal of downlink data 128.

In addition, suppose that travelling carriage is to the detection success of ascending wireless resource assignment information 127.Travelling carriage sends to the wireless base station according to ascending wireless resource assignment information 127 with upstream data 129.

At this moment, travelling carriage is guaranteed the zone 130 for storage ACK/NACK in PUSCH, sends to the wireless base station after being stored in NACK in this zone.This is because travelling carriage does not receive downlink data.

Like this, in PUSCH, guarantee to store the zone of ACK/NACK.When travelling carriage successfully detects down dispatch information and receives downlink data, send after will being stored in the zone as the error detection result's of downlink data ACK/NACK, when the detection of down dispatch information failure is not received downlink data, send after being stored in NACK in the zone.

Thus, travelling carriage sends data to the wireless base station with the same transformat with upstream data and ACK/NACK zone all the time, thereby the wireless base station can correctly receive upstream data.

Figure 15 is the functional block diagram of wireless base station.The each several part of Figure 15 has the function identical with the each several part of wireless base station shown in Figure 6 11.But the wireless base station of Figure 15 is with respect to the wireless base station 11 of Fig. 6, and difference is down dispatch information and ascending wireless resource assignment information are carried out respectively sending to travelling carriage after error detection coding and the error correction coding.In addition, difference is, the wireless base station of Figure 15 receives the PUSCH in the zone of having guaranteed storage ACK/NACK.Below, only the part different from Fig. 6 described.

Relative with the wireless base station 11 of Fig. 6, the wireless base station of Figure 15 by the 132b of error detection coding section, 132e and the 132c of error correction coding section, 132f to encoding respectively with the ascending wireless resource assignment information that control data generating unit 132d exports with the down dispatch information of control data generating unit 132a output with from upstream data from downlink data.

In addition, the reception signal processing part 132l of the wireless base station of Figure 15 identifies the ACK/NACK zone of PUSCH, extracts ACK/NACK from this zone, outputs to lsb decoder 132m.

Figure 16 is the functional block diagram of travelling carriage.The each several part of Figure 16 has the function identical with the each several part of travelling carriage shown in Figure 7 12.But the travelling carriage of Figure 16 is with respect to the travelling carriage 12 of Fig. 7, and difference is, down dispatch information and ascending wireless resource assignment information after encoding are respectively received.In addition, difference is to guarantee to store the zone of ACK/NACK in PUSCH.Below, only the part different from Fig. 7 described.

The signal that the travelling carriage of Figure 16 receives is encoded respectively to down dispatch information and ascending wireless resource assignment information and is obtained.Thereby, relative with the travelling carriage of Fig. 7, in the travelling carriage of Figure 16, by the 142c of error correction decoding section, 142f down dispatch information and ascending wireless resource assignment information are carried out respectively error correction decoding, by error detection lsb decoder 142d, 142g they are carried out respectively the error detection decoding.

ACK/NACK generating unit 142l generates ACK/NACK according to the error detection result of downlink data.In addition, when not receiving downlink data, generate NACK.

Transmitted signal handling part 142q guarantees to store ACK/NACK in PUSCH zone.Then, the ACK/NACK behind the coding is stored in the zone of guaranteeing, sends to the wireless base station with upstream data.

Like this, travelling carriage arranges all the time the zone of storing ACK/NACK and sends ACK/NACK in PUSCH.Thus, the wireless base station can receive the PUSCH of identical traffic form all the time, thereby correctly receives upstream data.

Then, explain the 5th execution mode of the present invention with reference to accompanying drawing.In the 5th execution mode, travelling carriage is given expression and is had or not the information of ACK/NACK as control information when sending upstream data.

Figure 17 is the figure that the action of the wireless base station of the 5th execution mode and travelling carriage is shown.There is shown down dispatch information 151,157, ascending wireless resource assignment information 152,158 and downlink data 153,159.The control information 156,161 that the ACK/NACK zone 155 of in addition, show upstream data 154,160, guaranteeing in PUSCH and expression have or not ACK/NACK.And, respectively with down dispatch information 151,157 and ascending wireless resource assignment information 152,158 the coding after send to travelling carriage.

Suppose that travelling carriage is to the detection success of down dispatch information 151.Travelling carriage is according to down dispatch information 151, downlink data receiving 153.

In addition, suppose that travelling carriage is to the detection success of ascending wireless resource assignment information 152.Travelling carriage sends to the wireless base station according to ascending wireless resource assignment information 152 with upstream data 154.

At this moment, travelling carriage is guaranteed the zone 155 for storage ACK/NACK in PUSCH, gives the control information 156 that zone 155 has been guaranteed in expression.Control information for example represents with bit information, represents to have guaranteed ACK/NACK zone 155 with 1, represents not guarantee ACK/NACK zone 155 with 0.

And travelling carriage receives downlink data 153 to the detection success of down dispatch information 151.Thereby travelling carriage will represent that this error detection result's ACK/NACK sends to the wireless base station in the zone in 155, and expression is provided with regional 155 control information 156(bit 1) send to the wireless base station.

Suppose that travelling carriage is to the detection failure of down dispatch information 157.In this case, travelling carriage does not carry out the reception ﹠ disposal of downlink data 159.

In addition, suppose that travelling carriage is to the detection success of ascending wireless resource assignment information 158.Travelling carriage sends to the wireless base station according to ascending wireless resource assignment information 158 with upstream data 160.

At this moment, because travelling carriage does not receive downlink data 159, thereby downlink data 159 is not carried out error detection.Thereby travelling carriage is not guaranteed the zone for storage ACK/NACK in PUSCH, will expression guarantee the control information 161(bit 0 in ACK/NACK zone) send to the wireless base station.

Like this, when travelling carriage sends to the wireless base station with ACK/NACK, give expression and whether guaranteed to send to the wireless base station for the control information in the zone that sends ACK/NACK.

Thus, the wireless base station can judge whether to have given ACK/NACK information in upstream data, thereby can correctly receive upstream data.

Figure 18 is the functional block diagram of wireless base station.The each several part of Figure 18 has the function identical with the each several part of wireless base station shown in Figure 15.But difference is, the wireless base station of Figure 18 extracts the control information that the ACK/NACK storage area has been guaranteed in the expression of sending from travelling carriage, based on the control information of extracting, judges to have or not ACK/NACK.Below, only the part different from Figure 15 described.

Relative with the wireless base station of Figure 15, in the wireless base station of Figure 18, receive signal processing part 172l and obtain the control information that comprises among the PUSCH.Lsb decoder 172m decodes to the control information that is obtained by reception signal processing part 172l.

ACK/NACK control information detection unit 172n judges that decoded control information is " 1 " or " 0 ".That is, determine whether and in PUSCH, comprise ACK/NACK.When comprising ACK/NACK, with this advisory to ACK/NACK detection unit 172p and upstream data handling part 172s.In PUSCH, guarantee the ACK/NACK zone if ACK/NACK detection unit 172p and upstream data handling part 172s identify, then carried out the judgement of ACK/NACK and the processing of upstream data.

Figure 19 is the functional block diagram of travelling carriage.The each several part of Figure 19 has the function identical with the each several part of travelling carriage shown in Figure 16.But the travelling carriage of Figure 19 is with respect to the travelling carriage of Figure 16, and difference is, gives whether expression has guaranteed the ACK/NACK zone in PUSCH control information.Below, only the part different from Figure 16 described.

ACK/NACK control information generating unit 182l generates expression and whether has guaranteed the control information in ACK/NACK zone.For example, when the detection of descending schedule information success, ACK/NACK will be sent to the wireless base station, thereby ACK/NACK control information generating unit 182l generates expression and guarantees the control information (bit 1) in ACK/NACK zone.When the detection of descending schedule information failure, ACK/NACK is not sent to the wireless base station, thereby ACK/NACK control information generating unit 182l generates expression and does not guarantee the control information (bit 0) in ACK/NACK zone.

When having generated ACK/NACK, transmitted signal handling part 182s guarantees ACK/NACK zone in PUSCH, and control information and upstream data are carried out sending to the wireless base station after multiplexing.

Like this, travelling carriage is given expression and whether is provided with the control information in ACK/NACK zone and sends to the wireless base station in PUSCH.Thus, the wireless base station can judge whether to comprise ACK/NACK in PUSCH, thereby what kind of form can identify the transformat that sends from travelling carriage be, thereby can correctly receive upstream data.

Then, explain the 6th execution mode of the present invention with reference to accompanying drawing.In the 6th execution mode, the wireless base station uses the form of ACK/NACK multiplexing and the form of multiplexing ACK/NACK not, and the signal that sends from travelling carriage is attempted reception.

Figure 20 is the figure that the action of the wireless base station of the 6th execution mode and travelling carriage is shown.There is shown down dispatch information 191,198, ascending wireless resource assignment information 192,199 and downlink data 193,200.In addition, show upstream data 194,201 and the storage ACK/NACK zone 195.And, show the PUSCH form 196,197,202,203 that can attempt receiving in the wireless base station.

Suppose that travelling carriage successfully detects down dispatch information 191.Travelling carriage is according to down dispatch information 191, downlink data receiving 193.

In addition, suppose that travelling carriage successfully detects ascending wireless resource assignment information 192.Travelling carriage sends to the wireless base station according to ascending wireless resource assignment information 192 with upstream data 194.

At this moment, because travelling carriage has successfully received down dispatch information 191, thereby in PUSCH, guarantee for the zone 195 of storage ACK/NACK ACK/NACK to be sent to the wireless base station.

The wireless base station is attempted receiving with the form 196 that comprises ACK/NACK zone 195 and the form 197 that does not comprise ACK/NACK zone 195 for the data that receive from travelling carriage.The PUSCH of the form of wireless base station docking harvest merit receives.In the example of Figure 20, because travelling carriage has sent the PUSCH of inclusion region 195, thereby the reception of 196 PUSCH of wireless base station using form success, 197 PUSCH of using form take defeat.And the success of reception and failed judgement for example are to carry out according to the error detection of upstream data.

Suppose that travelling carriage is to the detection failure of down dispatch information 198.In this case, travelling carriage does not carry out the reception ﹠ disposal of downlink data 200.

In addition, suppose that travelling carriage is to the detection success of ascending wireless resource assignment information 199.Travelling carriage sends to the wireless base station according to ascending wireless resource assignment information 199 with upstream data 201.

At this moment, because travelling carriage does not receive downlink data 200, thereby in PUSCH, do not guarantee the zone for storage ACK/NACK.Thereby travelling carriage only sends to the wireless base station with upstream data 201.

The wireless base station is attempted receiving with the form 202 that comprises the ACK/NACK zone and the form 203 that does not comprise the ACK/NACK zone for the data that receive from travelling carriage.The PUSCH of the form of wireless base station docking harvest merit receives.In the example of Figure 20, because travelling carriage has sent the PUSCH that does not comprise the ACK/NACK zone, thereby the reception of 203 PUSCH of wireless base station using form success, 202 PUSCH of using form take defeat.

Like this, receive data is attempted with the transformat both sides that can send from travelling carriage, comprise the transformat in ACK/NACK zone and do not comprise the ACK/NACK zone in the wireless base station.

Thus, even sent the data of different transpost formats from travelling carriage, the wireless base station also can correctly receive upstream data.

Figure 21 is the functional block diagram of wireless base station.The each several part of Figure 21 has the function identical with the each several part of wireless base station shown in Figure 15.But difference is, the wireless base station of Figure 21 has the function of identifying for to the form of the data that receive from travelling carriage.Below, only the part different from Figure 15 described.

Relative with the wireless base station of Figure 15, in the wireless base station of Figure 21, receive form control part 212m and will receive signal processing part 212l, lsb decoder 212n, ACK/NACK detection unit 212o, the 212p of error correction decoding section, error detection lsb decoder 212q and upstream data handling part 212r and be controlled to be and use the form in ACK/NACK zone multiplexing and the form both sides in not multiplexing ACK/NACK zone come the data that receive are processed.Receive signal processing part 212l, lsb decoder 212n, ACK/NACK detection unit 212o, the 212p of error correction decoding section and upstream data handling part 212r and adopt the processing that in upstream data, is not detected wrong form by error detection lsb decoder 212q.

Figure 22 is the functional block diagram of travelling carriage.The each several part of Figure 22 has the function identical with the each several part of travelling carriage shown in Figure 16.But the travelling carriage of Figure 22 is with respect to the travelling carriage of Figure 16, and difference is, does not guarantee all the time the ACK/NACK zone.Below, only the part different from 16 described.

When downlink data had been carried out error detection, the ACK/NACK generating unit 222n of the travelling carriage of Figure 22 generated ACK/NACK.Therefore, owing to when the detection of down dispatch information failure, not generating the ACK/NACK zone, so the PUSCH that the travelling carriage of Figure 22 will comprise the PUSCH in ACK/NACK zone and not comprise the ACK/NACK zone sends to the wireless base station.

Like this, travelling carriage sends to the wireless base station according to the error detection of downlink data with ACK/NACK, and these 2 kinds of transformats of PUSCH that therefore will comprise the PUSCH in ACK/NACK zone and not comprise the ACK/NACK zone send to the wireless base station.The wireless base station carries out reception ﹠ disposal with these 2 kinds of transformats that comprise the transformat in ACK/NACK zone and do not comprise the ACK/NACK zone to the PUSCH from travelling carriage.Thus, even the transformat disunity that sends from travelling carriage, the wireless base station also can correctly receive upstream data.

Then, explain the 7th execution mode of the present invention with reference to accompanying drawing.In the 7th execution mode, when travelling carriage will send to the wireless base station for the ACK/NACK of downlink data and upstream data, in PUSCH, ACK/NACK and upstream data for downlink data are not carried out time division multiplexing.Travelling carriage pre-assigned PUCCH or with PUCCH that the Radio Resource that sends downlink data or descending control data is associated in send ACK/NACK for downlink data, in the PUSCH that is distributed by the ascending wireless resource assignment information, send upstream data.

Figure 23 is the figure that the action of the wireless base station of the 7th execution mode and travelling carriage is shown.Show in the drawings down dispatch information 231,238, ascending wireless resource assignment information 232,239 and downlink data 233,240.In addition, show the PUSCH 234,236,241 that sends upstream data, 243 and the PUCCH235,237,242,244 that sends ACK/NACK.

Suppose that travelling carriage successfully detects down dispatch information 231.Travelling carriage is according to down dispatch information 231, downlink data receiving 233.In addition, suppose that travelling carriage successfully detects ascending wireless resource assignment information 232.Travelling carriage sends upstream data according to ascending wireless resource assignment information 232.

Because travelling carriage receives downlink data 233, thereby downlink data 233 is carried out error detection, will send to the wireless base station as the ACK/NACK of its testing result.Travelling carriage sends to the wireless base station with ACK/NACK in PUCCH 235, in PUSCH 234 upstream data is sent to the wireless base station.That is, travelling carriage sends to the wireless base station to carrying out for the ACK/NACK of downlink data 233 and upstream data after multiplexing in frequency domain.

The wireless base station pre-assigned or with PUCCH that downlink data or downlink data are associated in attempt the ACK/NACK for downlink data 233 is received.And because travelling carriage is successful to the detection of down dispatch information 231, thereby the wireless base station receives ACK/NACK in PUCCH 237.In addition, in PUSCH 236, receive upstream data.

Suppose that travelling carriage is to the detection failure of down dispatch information 238.In this case, travelling carriage does not carry out the reception ﹠ disposal of downlink data 240.

In addition, suppose that travelling carriage is to the detection success of ascending wireless resource assignment information 239.Travelling carriage sends upstream data according to ascending wireless resource assignment information 239 by PUSCH 241.

On the other hand, because travelling carriage does not carry out the reception ﹠ disposal of downlink data 240, thereby ACK/NACK is not sent to the wireless base station.In this case, travelling carriage does not send any data in PUCCH 242.

ACK/NACK is attempted receiving in the wireless base station in PUCCH 244.But, because travelling carriage does not send any data in PUCCH242, so the wireless base station detects DTX.The wireless base station receives upstream data in PUSCH 243.

Like this, owing to being divided into respectively PUCCH and PUSCH and independence for the ACK/NACK of downlink data and the Radio Resource that sends upstream data, thereby inconsistent between the transmission form of the PUSCH that predicts of the transmission form of the PUSCH that sends of the platform that can not be moved and wireless base station.In addition, no matter have or not the transmission upstream data, all send by PUCCH, thereby can carry out independently transmitting-receiving for the ACK/NACK of downlink data with upstream data.

Figure 24 is the functional block diagram of wireless base station.The each several part of Figure 24 has the function identical with the each several part of wireless base station shown in Figure 15.But difference is, in the wireless base station of Figure 24, decodes and judges by 253 couples of ACK/NACK/DTX of PUCCH Return Reception Dept..In addition, difference is, 254 pairs of upstream datas of PUSCH Return Reception Dept. carry out reception ﹠ disposal.Below, only the part different from Figure 15 described.

The decoding data of the lsb decoder 252m of PUCCH Return Reception Dept. 253 to sending from travelling carriage by PUCCH.ACK/NACK/DTX detection unit 252n judges ACK/NACK according to decoded data.If there is no decoded data, then ACK/NACK/DTX detection unit 252n detects DTX.

The 252o of error correction decoding section of PUSCH Return Reception Dept. 254 is to carrying out error correction decoding by PUSCH from the upstream data that travelling carriage sends.Error detection lsb decoder 252p carries out the error detection decoding to the upstream data that sends from travelling carriage by PUSCH.Upstream data handling part 252q processes the upstream data that sends by PUSCH.

Figure 25 is the functional block diagram of travelling carriage.The each several part of Figure 25 has the function identical with the each several part of travelling carriage shown in Figure 16.But difference is, in the travelling carriage of Figure 25, generates ACK/NACK by PUCCH transmission processing section 263, encodes.In addition, difference is, carries out transmission processing by 264 pairs of upstream datas of PUSCH transmission processing section.Below, only the part different from Figure 16 described.

The ACK/NACK generating unit 262l of PUCCH transmission processing section 263 generates ACK/NACK according to downlink data.Lsb decoder 262m encodes to the ACK/NACK that generates, and processes so that send in PUCCH.

The upstream data generating unit 262n of PUSCH transmission processing section 264 generates upstream data.The 262o of error detection coding section carries out error detection coding to upstream data.The 262p of error correction coding section carries out error correction coding to upstream data, and processes so that send in PUSCH.

Like this, travelling carriage sends ACK/NACK in PUCCH, sends upstream data in PUSCH.Thus, PUSCH can not occur at the place, wireless base station send the inconsistent of form and PUSCH transmission form, thereby can correctly receive upstream data.

Principle of the present invention below just is shown.And, to those skilled in the art, can carry out various distortion and change, the invention is not restricted to above-mentioned definite structure and the application examples that illustrates and illustrate, corresponding whole variation and equivalent all are regarded as falling in the scope of the present invention that is limited by claims and equivalent thereof.
