Description
The application be that on 01 09th, 2008, application number are 200880007805.1 the applying date, denomination of invention divides an application for the application for a patent for invention of " being used for equipment and method in the single carrier-frequency division multiple access system Resources allocation ".
Technical field
The present invention relates to a kind of method and apparatus for effectively distribute the control channel transfer resource at single-carrier frequency division multiple access (SC-FDMA) wireless communication system, when in same transmission period, sending Packet Data Channel and control channel.
Background technology
Fig. 1 shows as the transmitter in centralized FDMA (LFDMA) system of a class SC-FDMA system.Although this transmitter is configured such that and uses discrete Fourier transform (DFT) (DFT) and contrary fast fourier transform (IFFT) in Fig. 1, any other configuration also is applicable to this transmitter.
With reference to Fig. 1, be convenient to utilize minimum hardware complexity to change the LFDMA system parameters with DFT and IFFT.Consider OFDM (OFDM) and the difference of SC-FDMA on transmitter configuration, the LFDMA transmitter also comprises DFT precoder 101 at the front end of IFFT processor 102, is used for the multi-carrier transmission of OFDM transmitter.In Fig. 1, send (TX) modulated symbol 103 and offered DFT precoder 101 by piece.DFT output is mapped to the IFFT input in the frequency range that comprises continuous subcarrier.The effect of mapper 104 is to be mapped to actual frequency band with sending modulated symbol.
Fig. 2 shows the transfer of data from described subscriber equipment in the resource that is assigned with of subscriber equipment (UE) in traditional SC-FDMA system.
With reference to Fig. 2, limit a Resource Unit (RU) 201 by the one or more subcarriers on the frequency and temporal one or more SC-FDMA code element.For transfer of data, divide two RU that are equipped with the oblique line indication to UE1, and divide 3 RU that are equipped with the round dot indication to UE2.
Wherein the RU of UE1 and UE2 transmission data fixes in time, and is continuous in set frequency band.This resource is distributed or the scheme of transfer of data is optionally distributed the frequency resource that good channel condition is provided to each UE, thereby utilizes limited system resource maximum system performance.For example, compare with the piece in other frequency bands, the piece with oblique line provides better characteristics of radio channels to UE1, and compares with the piece in other frequency bands, provides better characteristics of radio channels with the piece of round dot to UE2.Option ground distributes the resource with better channel response to be known as the frequency selectivity resource and distributes or frequency selective scheduling.Aforesaid uplink data transmission from UE to the Node B is the same with utilizing, and frequency selective scheduling also is applied to the downlink transmission from the Node B to UE.On down link, represent respectively that with the RU of oblique line and round dot mark Node B wherein sends the resource of data to UE1 and UE2.
Yet frequency selective scheduling is always ineffective.Thereby for the fast-changing UE of fast moving and experience channel status, frequency selective scheduling also is not easy.More particularly, although the node B scheduling device has distributed frequency band in the relatively good channel status to UE in preset time, but when UE sent data from the Node B receiving resource allocation information and the resource of planning distributing, UE was arranged in the channel circumstance that significantly changes.Therefore, selected frequency band can not be guaranteed relatively good channel status for UE.
Even be used for continuously service transfer of data, that be similar to the voice (VoIP) based on the internet in the frequency resource that needs small amount, if UE reports its channel status about frequency selective scheduling, then signaling consumption also may be sizable.In this case, it is more effective using frequency hopping (frequency hopping) rather than frequency selective scheduling.
Fig. 3 shows the frequency hopping in the traditional F DMA system.
With reference to Fig. 3, distribute to the frequency resource that UE is used for transfer of data and change according to the time.Frequency hopping has between data transfer period so that the effect of channel quality and interference randomization (randomize).Because data are sent out in time dependent frequency resource, so at each time point, data have the different characteristics of channel and disturbed by the different UEs in the neighbor cell, thereby have obtained diversity.
Yet, if when RU jumped with independent pattern (independent pattern) in SC-FDMA system as shown in Figure 3, frequency hopping was infeasible.For example, if RU 301 and 302 is assigned to different UE, then it doesn't matter.Yet, if RU 301 and 302 the two all be assigned to single UE, they jump to the position of RU 303 and 304 by frequency hopping in next transfer point.Because RU 303 and 304 is discontinuous, so UE can not send data in these two RU.
In this contextual situation, in order to obtain the frequency diversity in the SC-FDMA system, open mirror image (mirroring) is to replace frequency hopping, as shown in Figure 4.
Traditionally, RU is with respect to the centre frequency of the whole frequency band that can be used for transfer of data and mobile symmetrically.For example, in the A of residential quarter, in next transmission time, RU 401 is mirrored onto RU 403, and RU402 is mirrored onto RU 404.In the same way, in the B of residential quarter, in next transmission time, RU 405 is mirrored onto RU 406.Mirror image so that continuous RU can jump continuously, thereby satisfy single carrier performance during the frequency hopping.
Shortcoming with frequency hopping of frequency diversity is: because except come with respect to centre frequency the mirror image can't mobile RU, so the jump pattern is fixed.This means in a certain degree to obtain frequency diversity, but be difficult to obtain interference randomization.When the RU that jumps to relative position returned its origin-location by mirror image, only a kind of RU jump pattern can be used.Therefore, even when having a plurality of residential quarter, each residential quarter can not have different patterns.
With reference to Fig. 4, within a time period, if be assigned to UE among the A of residential quarter with the RU 402 of round dot mark, and be assigned to UE among the B of residential quarter with the RU 405 of monocline wire tag, then because in the mirror image scheme, only there is a kind of frequency hop pattern to use, so the UE among the UE among the A of residential quarter and the residential quarter B disturbs.If the UE among the UE among the B of residential quarter and the residential quarter A is contiguous, then cause the remarkable interference to the UE among the A of residential quarter.As a result, utilization is worsened by the quality of reception with the UE of the residential quarter A of the RU of round dot mark.

Embodiment
Provide in the present note definition such as the theme of concrete structure and element to help complete understanding the preferred embodiments of the present invention.Therefore, those of ordinary skills will be appreciated that, in the situation that do not deviate from scope and spirit of the present invention, can make various changes and modification to the embodiments described herein.In addition, purpose has for clarity and conciseness been omitted the description to known function and structure.
The preferred embodiments of the present invention provide a kind of method, be used in each scheduled time, when in different RU, sending data, improve interference randomization between the residential quarter by common frequency hopping or mirror image scheme, to obtain frequency diversity in the single carrier performance in satisfying the uplink SC-FDMA system.
In order to understand better the present invention, as the data channel of giving a definition.
Frequency scheduling (FS) band: by one group of RU of frequency selective scheduling distribution.They are continuous or disperse.
Frequency hopping (FH) band: the one group of RU that sends for obtaining frequency diversity.These RU can't help frequency selective scheduling and distribute.They are continuous or disperse.A FH band can comprise one or more sub-FH bands.
Mirror image: RU is with respect to symmetrical jump the from left to right and from right to left of the center RU in central subcarrier or the sub-FH band.
Hopping time: the time that the RU that distributes jumps or is mirrored.Depend on how to adopt and jump or mirror image, RU has the following time period.
1. when jumping between jump and subframe in supporting subframe, this time period is a time slot.
2. when only supporting to jump between subframe, this time period is a subframe.
It is a kind of for opening or closing the method for mirror image according to different mirror image opening/closing (mirroring on/off) pattern for each residential quarter that embodiment 1 provides.Use the different mirror image opening/closing pattern for different districts as much as possible and reduce the effect that the possibility of opening mirror image simultaneously in the residential quarter has maximized randomize inter-cell interference.
Fig. 5 A and Fig. 5 B illustrate the method according to the first embodiment of the present invention.Fig. 5 A illustrates the timeslot-based mirror image of not considering HARQ, and Fig. 5 B illustrates the independently mirror image for each HARQ process.
With reference to Fig. 5 A, there is residential quarter 501 and 502 (residential quarter A and residential quarter B).When jumping in the hypothesis subframe, the hopping time section is time slot.Take time slot as the basis, in the A of residential quarter according to opening (on), open, open, close (off), opening, close, close, close ... pattern 503 carry out mirror image at each hopping time, in the B of residential quarter according to opening, close, open, open, close, close, open, opening ... pattern 512 carry out mirror image at each hopping time.
In the A of residential quarter, RU 504 is assigned to UE A at hopping time k.Because be to open at next hopping time (k+1) for the mirror image of UE A, so UE A uses RU 505 in time slot (k+1).At hopping time (k+3) mirror image for closing, thereby UE A sends data in the RU 506 identical with the RU that uses in the last time slot (k+2) in time slot (k+3).Similarly, because at hopping time (k+6) mirror image for closing, so UE A sends data in the RU507 identical with the RU that uses in the last time slot (k+5) in time slot (k+6).
In an identical manner, in the B of residential quarter, RU 508 is assigned to UE B in time slot k.Because at next hopping time (k+1) mirror image for closing, so UE B uses RU 509 in time slot (k+1).At hopping time (k+3), mirror image is for opening, thereby UE B uses RU 510 in time slot (k+3).Similarly, because at hopping time (k+6) mirror image for opening, so UE B uses RU 511 in time slot (k+6).
In each residential quarter, mirror image is opened or is closed at each hopping time according to different patterns.Therefore, although the UE in the different districts may use same RU at given time slot, owing to having used different mirror image opening/closing patterns, in next time slot, use the possibility of same RU so reduced them.For example, in time slot k, RU 504 and 508 is assigned to respectively UE A among the A of residential quarter and the UE B among the B of residential quarter.If UE B and residential quarter A are contiguous, then UE A probably is subject to the remarkable interference of UE B.Yet, because UE A opens mirror image at next hopping time (k+1), so UE A sends data in RU 505 in time slot (k+1), and mirror image is closed for UE B, so UE B sends data in the RU 509 identical with the RU that uses in the last time slot.Thereby.UE A uses different RU with UE B in time slot (k+1).
Be that in the mirror method shown in Fig. 5 B and similar part at the mirror method shown in Fig. 5 A different residential quarters uses different mirror image opening/closing patterns, and the difference of the former with the latter is: in Fig. 5 B, RU comes mirror image with respect to the RU in the same HARQ process, rather than comes mirror image with respect to the RU in the last time slot as Fig. 5 A.
In Fig. 5 B, mirror image is opened the UE of hopping time k in residential quarter 513 (residential quarter A).Thereby UE uses the RU 517 that will use in the last time slot (k-RTT+1) of same HARQ process to carry out the RU 518 that mirror image obtains, rather than uses the RU that will use in last time slot (k-1) to carry out the RU that mirror image obtains.RTT represents two-way time (Round Trip Time), is defined as when being to negate initial transmission time when confirming (NACK) and being ACK about the response of retransmission data about the response that sends data.Therefore, the data that send in RU 518 and 519 are re-transmitted version of the data of transmission in RU 516 and 517, perhaps belong to the same HARQ process with the data that send in RU 516 and 517.Be convenient to define wherein for initialization and the mirror image opening/closing pattern of retransmitting the different RU of use based on the mirror image of HARQ RTT.Although have this advantage, management has increased complexity for the different mirror image opening/closing pattern of each HARQ process.In this context, following definite mirror image opening/closing pattern.
(1) according to a sequence at each hopping time opening/closing mirror image.Need this sequence to indicate and open or close mirror image, and do not indicate position about the RU that jumps.Therefore, this sequence comprises two values.Usually, binary sequence comprises 0 and 1.
(2) generate a plurality of sequences and distribute to the residential quarter, so that different patterns is applied at least neighbor cell, thereby minimize RU conflict between them.For example, be assigned to each residential quarter such as one group of orthogonal code of Walsh (Walsh) yard, and each residential quarter is determined the mirror image opening/closing at each hopping time according to code value 0 or 1.Replacedly, the mirror image opening/closing can be determined according to the pseudo noise with the seed that is exclusively used in this residential quarter (PN) sequence in each residential quarter.Compare with front a kind of method, rear a kind of method has increased the randomization between the residential quarter, thereby has minimized the phenomenon that RU jumps according to same mode in different districts.The below will describe the present invention in the context based on the method for PN sequence.
In order to generate the PN sequence, use the cell-specific seed, and obtain same PN sequence, the UE in the same residential quarter should receive identical timing information.Timing information can be represented as absolute time and poor between the current time, perhaps can be represented as frame count common time such as System Frame Number (SFN).
Fig. 6 illustrates the operation that is used for determining at UE the mirror image opening/closing according to the first embodiment of the present invention.For from the UE receive data, Node B can be carried out identical operation.
With reference to Fig. 6, when node B scheduling was used for the RU of UE, UE generated the PN sequential value in step 601, and checked this PN sequential value in step 602.If the PN sequential value is 0, then UE determines to close mirror image in step 604.If the PN sequential value is 1, then UE determines to open mirror image in step 603.In step 605, UE is identified for the RU position of next transfer of data according to the mirror image opening/closing of determining in step 603 or 604.UE sends data in determined RU in step 606.
Mirror image causes jumping with respect to the RU of the symmetry at the center of whole FH band.Can detect the new RU that in next time slot, uses based on the information about the RU that in last time slot, uses.Mirror image is represented as such as equation (1):
H(r)=N
FH-r
……(1)
Wherein, r represents the RU as the mirror image basis.The mirror image basis is the RU that uses in last time slot in Fig. 5 A and the RU that uses in the last time slot of same HARQ process in Fig. 5 B.H (r) is illustrated in the time slot RU that mirror image obtains is carried out on the mirror image basis.N
FHBe illustrated in the sum of the RU in the FH band.
Fig. 7 illustrates the UE according to the first embodiment of the present invention.
With reference to Fig. 7, data symbols maker 703 generates the data symbols that will send.Determined the data volume that in each Transmission Time Interval (TTI), can send by node B scheduling.String also (S/P) transducer 704 converts the sequence of data symbols to the paralleled code element sequence.DFT processor 705 converts the paralleled code element sequence to frequency-region signal, to be used for the SC-FDMA transmission.The DFT size equals from the quantity of the data symbols of data symbols maker 703 generations.Mapper 706 is mapped to frequency-region signal the frequency resource of distributing to UE based on the RU information that receives from Data Transmission Control Unit 702.Data Transmission Control Unit 702 is based on the UR information of dispatching and mirror image opening/closing Information generation RU information.Each residential quarter has different mirror image opening/closing patterns according to the PN sequence.Therefore, need PN sequence generator 701.Use the output of PN sequence generator 701 to decide the RU that will use according to preceding method.Signal after IFFT processor 707 will shine upon is converted to time-domain signal.And string (P/S) transducer 708 is converted to time-domain signal for the serial signal that transmits.
Fig. 8 illustrates the Node B according to the first embodiment of the present invention.
With reference to Fig. 8, S/P transducer 807 is converted to parallel signal with the signal that receives, and fft processor 806 is converted to frequency signal with parallel signal.Go mapper 805 based on the RU assignment information about each UE of being determined by uplink scheduler 802, go mapping for the frequency-region signal of different UEs.Uplink scheduler 802 is used the RU information of dispatching and based on the mirror image opening/closing Information generation of the mirror image opening/closing pattern RU information about each UE.Because each residential quarter has different mirror image opening/closing patterns, so need PN sequence generator 801.Decide the RU that will extract from it data according to preceding method based on the output of PN sequence generator 801.IDFT processor 804 is converted to time-domain signal with the mapping signal that goes of the UE (being UE 1) of expectation.P/S transducer 808 is converted to serial signal with time-domain signal.The data that data symbol decoder 803 demodulation receive from UE.
Sub-FH interband jump opening/closing and mirror image opening/closing are combined, and by selecting a combination to be identified for the position of the RU of transfer of data, so that each residential quarter has different patterns.That is to say, the resource of whole system frequency band is divided into FH band and FS band, and is disclosed in the channel architecture that enough frequency agility gains is provided in the FH band and obtains enough available band in the FS band.
Fig. 9 illustrates channel architecture according to a second embodiment of the present invention.
With reference to Fig. 9, define sub-FH in the both sides of whole frequency band and be with 901 and 903, and sub-FH is defined as FS with the centre frequency band between 901 and 903 and is with 902.Use FS can jump to sub-FH with 902 UE and be with 901 and 903, thereby obtain enough frequency agility gains.Because FS is continuous distributing with the maximization cline frequency with 902 frequency, so can improve maximum data rate.
Next, will make description to following method: consider the single carrier performance in the disclosed channel architecture, be used in each FH band, carrying out sub-FH interband jump and mirror image to obtain enough frequency diversity gain, make it possible to simultaneously carry out variable RU and distribute.As among the first embodiment, jump and the opening/closing mirror image at the sub-FH interband of each hopping time opening/closing according to the cell-specific pattern.
As shown in table 1, obtain four kinds of combinations of sub-FH interband jump opening/closing and mirror image opening/closing.At each hopping time, select a kind of combination, and use selected combination according to different patterns each residential quarter to be used and jump and/or mirror image.

Figure 10 A to Figure 10 D illustrates method according to a second embodiment of the present invention.
Figure 10 A and Figure 10 B are based on the hypothesis of supporting to jump in the TTI in residential quarter 1001 and 1007 (residential quarter A and residential quarter B).Therefore, the hopping time section is time slot.
With reference to Figure 10 A and Figure 10 B, come Selection and Constitute for residential quarter A according to the order of 3-1-4-3-2-1-2-3, and come Selection and Constitute for residential quarter B according to the order of 3-4-2-1-3-2-1-4.
Although use RU 1002 at hopping time k residential quarter A, it jumps by sub-FH interband and mirror image selection RU 1005 according to combination 1 at hopping time (k+1).At next hopping time (k+2), residential quarter A only carries out sub-FH interband jump and does not carry out mirror image according to combination 4, thereby selects RU 1003.Because for hopping time (k+4) combination 2 is set, so residential quarter A selects RU 1004 and do not carry out sub-FH interband and jump and mirror image.
At hopping time k, residential quarter B selects to be used for the same RU 1008 of residential quarter A.At hopping time (k+1), with jump by sub-FH interband according to combination 1 and mirror image the two select the residential quarter A of RU 1005 to compare, residential quarter B only jumps by sub-FH interband according to combination 4 and not by mirror image selection RU 1009.Although other UE in time slot (k+1) small area B may use the RU identical with RU 1005, each time from the interference of different UEs rather than with better interference randomization gain is provided conflicting of same UE.
In Figure 10 C and Figure 10 D, carry out sub-FH interband jump and mirror image for the RU of the last data transmission that is used for same HARQ process rather than at the RU that last hopping time uses.
With reference to Figure 10 C, jump rather than the sub-FH interband of the RU that uses at hopping time (k-1) jumps and selects RU 1013 at the sub-FH interband of the RU 1014 of the last data transmission of hopping time k by being used for same HARQ process.For hopping time k combination 4 is set, this means jumps for the sub-FH interbands of RU 1014 opens and mirror image is closed.Thereby, select RU 1013 at hopping time k.At the hopping time k+1 that is provided with combination 3, RU 1013 quilt FH interbands jump and are mirrored to RU 1012.
Next, will come the method for the combination of chooser FH interband jump opening/closing and mirror image opening/closing to make description with sequence to being used for.
(1) because need sequence to indicate the combination of from four kinds of combinations of sub-FH interband jump opening/closing and mirror image opening/closing, selecting, and do not indicate position for the RU that jumps, so can utilize 4 values to form this sequence.Usually, two of quaternary sequence or combination binary sequences are used to indicate the purpose of selected combination.Can generate this sequence with conventional method, thereby not provide its detailed description here.
(2) generate a plurality of sequences and distribute to the residential quarter, so that different patterns is applied at least neighbor cell, thereby minimize RU conflict between them.For example, be assigned to each residential quarter such as one group of orthogonal code of Walsh (Walsh) code according to corresponded manner one by one, and each residential quarter is come Selection and Constitute at each hopping time according to sequential value.Replacedly, Selection and Constitute can be come according to the PN sequence with the seed that is exclusively used in this residential quarter in each residential quarter.Compare with front a kind of method, rear a kind of method has increased the randomization between the residential quarter, thereby has minimized the phenomenon that RU jumps according to same mode in different districts.The below will describe the second embodiment of the present invention in the context based on the method for PN sequence.
In order to generate the PN sequence, use the cell-specific seed, and obtain same PN sequence, the UE in the same residential quarter should receive identical timing information.Timing information can be represented as absolute time and poor between the current time, perhaps can be represented as frame count common time such as SFN.
Figure 11 illustrates the operation of UE according to a second embodiment of the present invention.When Node B during from the UE receive data, same operational applications is in this Node B.
With reference to Figure 11, when node B scheduling was used for the specific RU of UE, UE generated the PN sequential value in step 1101, and determined that in step 1102 the PN sequential value is 1,2,3 or 4.If the PN sequential value is 1, then UE selects mirror image to open the combination of jumping and opening with sub-FH interband in step 1103.If the PN sequential value is 2, then UE selects mirror image to close the combination of jumping and closing with sub-FH interband in step 1104.If the PN sequential value is 3, then UE selects mirror image to close the combination of jumping and opening with sub-FH interband in step 1105.If the PN sequential value is 4, then UE selects mirror image to open the combination of jumping and closing with sub-FH interband in step 1106.In step 1107, UE is identified for the RU of transfer of data by mirror image and/or jump according to selected combination.UE sends data in determined RU in step 1108.
Except PN sequence generator 701 and 802 generates in 4 values 1 to 4 one and the value that generates offered Data Transmission Control Unit 702 and the position of uplink scheduler 802 with definite RU, transmitter according to a second embodiment of the present invention has and the configuration identical with receiver according to the transmitter of the first embodiment of the present invention with receiver.
Figure 12 illustrates the channel architecture of a third embodiment in accordance with the invention.
For wherein existing as shown in figure 12 a plurality of sub-FH bands and jumping always occur in system between the sub-FH band, a kind of method of determining the mirror image opening/closing for each residential quarter according to different patterns is disclosed.Use different mirror image opening/closing patterns to reduce the possibility of in different districts, carrying out at one time mirror image for different residential quarters, thereby cause the randomization of maximized presence of intercell interference.
Figure 13 and Figure 14 illustrate the method for a third embodiment in accordance with the invention.Particularly, Figure 13 illustrates the mirror method that is independent of HARQ, and Figure 14 illustrates the method for carrying out mirror image based on the HARQ process.
With reference to Figure 13, the two all supports to jump in the subframe because suppose residential quarter 1301 and 1311 (residential quarter A and residential quarter B), so the hopping time section is time slot.In the A of residential quarter according to opening, open, close, close, open, close, close, closing ... pattern 1310 carry out mirror image at each hopping time, in the B of residential quarter according to opening, close, close, open, close, close, open, opening ... pattern 1320 carry out mirror image at each hopping time.
In the A of residential quarter, if be assigned to UE at the sub-FH of hopping time k with the RU 1302 among the #1, then because always using sub-FH interband jumps, so it jumps to sub-FH band # 2, and be mirrored according to mirror image pattern 1310.Therefore, UE uses RU 1303 in time slot (k+1).At next hopping time (k+2), UE closes and selects RU 1304 by jumping to sub-FH band # 1 and mirror image.Close with jump and the mirror image of #2 because occur to sub-FH at next hopping time (k+3), so UE uses RU 1305 in time slot (k+3).
A compares with the residential quarter, for the different mirror image opening/closing pattern of residential quarter B definition.Particularly, come opening/closing mirror image at each hopping time according to different modes for each residential quarter.Although may select same RU at given hopping time residential quarter A and residential quarter B, the third embodiment of the present invention has reduced in two residential quarters the possibility at the same RU of next jump selection of time.
For example, when same RU 1302 and 1312 was distributed to respectively UE A among the A of residential quarter and the UE B among the B of residential quarter for a time period, if UE B and residential quarter A are contiguous, then UE A probably was subject to remarkable interference from UE B at hopping time k.Yet, because residential quarter A next hopping time (k+1) carry out that sub-FH interband jumps and mirror image the two, so UE A in time slot (k+1) in RU 1303 interior transmission data, and sub-FH interband jumps and opens and mirror image is closed for UE B, thus UE B in time slot (k+1) in RU 1313 interior transmission data.Like this, UE A uses different RU with UE B in time slot (k+1), thereby has avoided the lasting interference from same UE.
Mirror method shown in Figure 14 and the similar part of the mirror method shown in Figure 13 are to carry out mirror image and the different different mirror image opening/closing patterns of residential quarter use after sub-FH interband jumps, and the difference of the former with the latter is: in Figure 14, come mirror image RU with respect to the RU in the same HARQ process, rather than as among Figure 13, coming mirror image RU with respect to the RU that uses in the last transmission time.
That is to say, at hopping time (k+RTT), the RU 1407 that UE in the residential quarter 1401 (residential quarter A) uses RU 1406 mirror images that will use in the time slot (k+1) of same HARQ process to obtain, rather than the RU that obtains of the use RU mirror image that will in last time slot (k+RTT-1), use.Based on the mirror image of HARQ RTT be convenient to define wherein for initial transmission with retransmit the mirror image opening/closing pattern that uses different RU, thereby maximized the interference diversity effect.
Except sub-FH interband jump all occured the institute during selecting RU if having time, UE determined the mirror image opening/closing according to the mode identical with the first embodiment of the present invention.
In order to realize the third embodiment of the present invention, provide for example jump pattern formula of equation (2).UE knows the Resource Block that will use in each transmission time with this jump pattern formula and the index of the Resource Block of dispatching.Equation (2) jump to use skew (sub-band-based shifting) based on subband for intersubband, and as follows:

Hop(i) be illustrated in the index of hopping time (t), the Resource Block after jumping, N_RB represents to can be used for the sum of the Resource Block of transfer of data, and N
oAnd N
sIt is the maximum quantity that can be scheduled for the Resource Block of carrying out the UE that jumps.
If the total N_RB of Resource Block is not the multiple of sub band number M, then particular sub-band has the number of resource blocks N than other each subband
oFew number of resource blocks N
sBecause equation (2) supposes only to have a subband to have still less number of resource blocks, so calculate N by equation (3)
oAnd N
s, as follows:
In equation (2), h (t) expression cyclic shift degree, be according to the bit value of random sequence select 0,1 ..., among the M} one.h(0)=0。M (i) is the parameter of determining at hopping time (i) mirror image opening/closing, is { among 0, the 1} one.Select m (i) according to the bit value of random sequence, perhaps select m (i) by h (i)=x2 and m (i)=xMod (2), wherein x be according to the bit value of random sequence select 0,1 ..., among the M} one.If m (i)=0, then mirror image is closed, and if m (i)=1, then mirror image is opened.
Particularly, in equation (2), at first calculate skew O in the scheduling time of the Resource Block of dispatching by the first row of equation (2)
sO
sHow far the Resource Block that indication is recycled displacement has apart from the cyclic shift reference point.
Because following former thereby introducing O
sWhen the total N_RB of Resource Block was not the multiple of sub band number M, subband did not have identical stock number, so that the intersubband that leads to the failure jumps.Therefore, in the third embodiment of the present invention, subband formed so that subband has the number of resource blocks N than other each subbands
oFew number of resource blocks N
s, and O
sBe used for indicating the subband with number of resource blocks still less to UE.
For example, if N_RB be 22 and M be 4, then can be with subband arrangement for so that the first subband has 4 Resource Block, and other each subbands have 6 Resource Block.In this sub band structure, if O
sLess than 4, then UE knows that the Resource Block of dispatching is present in the less subband.
Then, according to first conditional statement of equation (2), the Resource Block of dispatching is according to skew O
sWith respect to Resource Block 0 to N

sBe mirrored in the individual Resource Block.If m (i)=0, then mirror image is closed.
If O

s, the Resource Block that this hint is dispatched is present in the normal sub-band, then carries out cyclic shift according to second conditional statement of equation (2), then at N
oCarry out mirror image in the individual Resource Block.If m (i)=0, then mirror image is closed.
Depend on subband arrangement, can expect further that in a plurality of subbands each has N
sIndividual Resource Block, and in remaining a plurality of subband each has N
oIndividual Resource Block.For example, if given 4 subbands, then each in two subbands has 5 Resource Block, and in other two subbands each has 6 Resource Block.Can indicate the conditional statement of the equation (2) of the subband of dispatching easily to realize this situation by revising with skew.
If open or close mirror image according to the random pattern in each residential quarter, then continuous mirror image opening/closing has increased in different districts in same RU from the possibility of the transfer of data of UE.Consider so, with regard to channel quality, preferably when sending data by the HARQ process, obtain enough frequency diversities in each transmission time, be necessary to allow UE in such as the continuous data transmission situation of initial transmission and repeating transmission, to select different RU at least.For this reason, the fourth embodiment of the present invention discloses a kind of method of limited use, is used for generating when needed random mirror image pattern and determines the mirror image opening/closing according to this random mirror image pattern.In supporting subframe, jump and subframe between when jumping the two, in two kinds of jump schemes one always open at each hopping time mirror image, and come the opening/closing mirror image for another jump scheme according to random mirror image opening/closing pattern.
Figure 15 illustrate a fourth embodiment in accordance with the invention, always open mirror image for jumping between subframe and to determine the method for mirror image opening/closing for jumping in the subframe according to random mirror image opening/closing pattern.
As in the second embodiment of the present invention, sub-FH band is positioned at the both sides of band system band, and the FS band is inserted in the center frequency-band between the sub-FH band.In order to obtain frequency diversity gain, as in the third embodiment of the present invention, RU jumps between sub-FH band at each hopping time.
With reference to Figure 15, basis is opened, closes, is closed in residential quarter 1500 (residential quarter A) ... pattern hopping time generation mirror image in each subframe, in residential quarter 1520 (residential quarter B) according to closing, close, open ... pattern hopping time generation mirror image in each subframe.
When RU 1502 in the A of residential quarter at hopping time (k-RTT) when being assigned to UE, UE at next hopping time (k-RTT+1) by selecting RU 1503 according to the mirror image of mirror image opening/closing pattern.At the hopping time k as next transmission time of same HARQ process, mirror image is always opened.Be in the RU of diverse location for the RU that selects to send with last transmission time in same HARQ process, select RU 1504 by RU 1502 mirror images that will in first time slot (k-RTT) in last HARQ transmission time, use.Because close according to mirror image opening/closing pattern mirror image at next hopping time (k+1), so UE selects RU 1505.At the hopping time (k+RTT) as next transmission time of same HARQ process, mirror image is always opened.In order to select to be in the RU that sends in the last HARQ transmission time RU of diverse location, RU 1504 is mirrored onto RU 1506.Because close according to mirror image opening/closing pattern mirror image at next hopping time (k+RTT+1), so UE selects RU 1507.
In an identical manner, in the B of residential quarter, UE comes the opening/closing mirror image to jump to another sub-FH band by hopping time in each subframe according to random mirror image opening/closing pattern.That is to say, if in time slot (k-RTT), use RU 1508, then select RU 1509 at next hopping time (k-RTT+1) by closing mirror image according to mirror image opening/closing pattern.Because carry out mirror image in next HARQ transmission time for the RU 1508 that uses in the last transmission time of same HARQ process, so select RU 1510 at hopping time k.At hopping time (k+1), close according to mirror image opening/closing pattern mirror image, thereby select RU 1511.Because carry out mirror image in next HARQ transmission time for the RU 1510 that uses in the last transmission time of same HARQ process, so select RU1512 at hopping time (k+RTT).At hopping time (k+RTT+1), open according to mirror image opening/closing pattern mirror image, thereby select RU 1513.
Be apparent that by foregoing description, the present invention is by opening or closing mirror image according to different mirror image opening/closing patterns at each hopping time in each residential quarter, advantageously randomization presence of intercell interference, increased the frequency diversity effect.
