Technical field
The present invention relates to wireless communication field, the channel resource block mapping techniques of particularly accurate quadrature reverse link.
Background technology
In the last few years, be subjected to people's extensive concern for the multi-carrier transmission technology of representative with OFDM (Orthogonal Frequency Division Multiplexing is called for short " OFDM ").Multi-carrier transmission is decomposed into several independently sub data flows to data flow, and each sub data flow will have much lower bit rate.The low rate multimode symbol that forms with such low bit rate removes to modulate corresponding subcarrier, has just constituted the transmission system that a plurality of low rate symbol parallels send.
OFDM is as a kind of multiplex technique, with multi-way signal multiplexing on the different orthogonal subcarrier.Traditional frequency division multiplexing (Frequency Division Multiplexing is called for short " FDM ") technology is divided into several subchannels with bandwidth, and the centre reduces interference with the protection frequency band, and they send data simultaneously.Ofdm system is wanted much less than the bandwidth of traditional FDM system requirements.Because use noiseless quadrature carrier technology, single intercarrier need not to protect frequency band.Make that like this service efficiency of usable spectrum is higher.In addition, the OFDM technology can dynamically be distributed in the data on the subchannel.For obtaining maximum data throughout, multi-carrier modulator can distribute more data intelligently to the good subchannel of channel condition.
OFDM will through the coding data to be transmitted as frequency domain information, it is modulated to time-domain signal, and, then carries out the inverse process demodulation at receiving terminal in channel.The modulation and demodulation of ofdm system can be respectively by contrary discrete Fourier transform (DFT) (Inverse Discrete Fourier Transform, be called for short " IDFT ") and discrete Fourier transform (DFT) (Discrete Fourier Transform, abbreviation " DFT ") replace.By N point IDFT computing, be the frequency domain data sign reversing time domain data symbol, through after the carrier modulation, send in the channel.At receiving terminal, received signal is carried out coherent demodulation, then baseband signal is carried out N point DFT computing, the data symbol that can obtain to send.In actual applications, IDFT/DFT adopts contrary fast fourier transform (Inverse Fast Fourier Transform is called for short " IFFT ") and fast fourier transform (Fast Fourier Transform is called for short " FFT ") to realize.The employing of FFT technology makes the complexity of ofdm system reduce greatly, add the high-performance information processing device, programmable logic device (Programmable Logic Device for example, abbreviation " PLD "), digital signal processor (Digital Signal Processor, abbreviation " DSP "), microprocessor (MicroProcessor, abbreviation " μ P ") etc. development and application makes the realization of ofdm system be more prone to, and becomes most widely used a kind of multi-carrier transmission scheme.
By to the different subcarrier of different terminal distribution, can realize that the multiple access of OFDM inserts, i.e. OFDMA.In the OFDMA system, the resource different to the different terminals assignment (time, space, frequency resource) realizes different terminals sharing resource.Adopt up the having access to of OFDMA mode to be beneficial to the interference that reduces inside, sector.But when the reception antenna number of base station increases, the dimension of this access way will be restricted, and be unfavorable for obtaining maximum power system capacity.If adopt the mode of accurate orthogonal multiplex, then can reduce this restriction.
It is in a sector that accurate quadrature inserts, and identical bandwidth (channel resource) is distributed to a plurality of terminals.The information that the base station adopts the mode of spatial manipulation to come these terminals of demodulation to send over.Like this, when the reception antenna number was smaller, system can obtain the benefit of orthogonal multiplex, and when antenna number was many, power system capacity increased with the reception antenna number.
As shown in Figure 1, when accurate quadrature inserted, logic channel can be divided into many stalk trees.Logic channel node on the different subtrees is mapped on the identical physical channel resources, that is to say, has shone upon several logic channel tree fundamental nodes on the identical physical channel resources piece, is called one group of logic channel tree fundamental node.The terminal of different subtree correspondences is inequality.Disturb equalization in order to make between different subtrees, promptly in order to make the bigger logic channel tree fundamental node of mutual interference ratio can always in same physical channel resources, need not make the logic channel tree fundamental node that comprises in the logic channel tree fundamental node group of shining upon on the different physical channel resources pieces inequality.
At present, adopted the mode of random permutation to come the interference of user between the different subtrees of randomization in the prior art, the random sequence that is used for random permutation generates by the linear feedback shift register of 20 bits.At first, base station and terminal are according to the physics frame number, and sub-blaze etc. produce the shift register initial value of 20 bits, i.e. seed.Each physical frame generates different seeds, and each sub-blaze generates different seeds.Each frame, base station and terminal generate one group of random sequence with these seeds as the initial value of shift register, and Physical Resource Block shines upon one by one on logic channel tree fundamental node in the same subtree and the whole frequency band.Mapping relations are determined that by constant series for example, random sequence is 345201, P (0)=4 then, P (1)=5, P (2)=3, P (3)=0, P (4)=1, P (5)=2.That is to say that node 0 is mapped on the physical channel resources piece 4, node 1 is mapped to 5.In end side, if certain terminal is assigned to logic channel tree fundamental node 0, then in this frame, terminal to the subcarrier of physical channel resources piece 4, sends the data-modulated that will send.After the base station separated different subtrees by the mode of spatial manipulation, to the whole frequency band of the residing subtree of this terminal, the base station demodulated data from the subcarrier of physical channel resources piece 4, as this user's data bag, issued the upper strata.
In realizing process of the present invention, discover that through the inventor in actual applications, have following problem: the amount of calculation of terminal when modulating data is to Resource Block is bigger, and, can't guarantee the interference between the different layers in the accurate quadrature backward channel of equalization most desirably.
Cause the main cause of this situation to be, each terminal has only several with the base station according to the value relevant with this terminal in the whole random sequence of shift register generation, for example, in above-mentioned example, with the P (0) that has only corresponding to the relevant value of the terminal of node 0 in the random sequence 345201, be P (0)=4, but this terminal but have to calculate whole random sequence.And, for each physical frame, each terminal and base station all need according to frame number, sub-blaze, Hyper Frame Number etc. regenerate the shift register seed, regenerate whole random sequence by this shift register again, increased the amount of calculation of terminal when modulating data goes greatly to the physical channel resources piece.In addition, the random sequence that is generated can not guarantee that the number of times that certain terminal and another terminal take same physical channel resources piece is 1, thereby can't guarantee the interference between the different layers in the accurate quadrature backward channel of equalization most desirably.

Table 2 (c=3)
Similarly, as shown in table 2, be under 3 the situation at c, the sequence of the mapping of expression the 1st frame to the 10 frames that the terminal corresponding with logic channel tree fundamental node 0 calculated according to the Reed-Solomon yardage is 6,1,2,4,8,5,10,9,7,3; The sequence of the mapping of expression the 1st frame to the 10 frames that the terminal corresponding with logic channel tree fundamental node 1 calculated according to the Reed-Solomon yardage is 7,2,3,5,9,6,0,10,8,4; And the like.
Then, enter step 220, terminal will arrive the mapping mode of physical channel resources piece as the logic channel tree fundamental node of accurate quadrature reverse link with the sequence that is generated.That is to say that terminal will send data-modulated in corresponding Physical Resource Block according to the sequence that generates.With terminal corresponding with logic channel tree fundamental node 0 in the table 1 is example, this terminal modulates data on the physical channel resources piece 4 when the 1st frame, when the 2nd frame, modulate data on the physical channel resources piece 8, when the 3rd frame, modulate data on the physical channel resources piece 5, and the like.
Because each terminal only need generate the Reed-Solomon sign indicating number sequence relevant with this terminal, and this sequence comprised the mapping of the physical channel resources piece of these 10 time slots, that is to say that terminal all need not to calculate once more new sequence in these 10 time slots.Therefore, significantly reduce terminal and calculated the amount of calculation that the logic channel tree fundamental node of pairing accurate quadrature reverse link is mapped to the physical channel resources piece.
In addition, because the Reed-Solomon sign indicating number has good cross-correlation performance and autocorrelation performance, and has more sequence number.Therefore, can reduce the situation that certain terminal and another terminal take same physical channel resources piece for a long time, more effectively equalization the interference between the different layers in the accurate quadrature backward channel.At the foregoing description, in table 1, the physical channel resources piece that logic channel tree fundamental node 2 shines upon in 1 to 10 frame is respectively 6,10,7,1,0,9,5,8,3,4.In table 2, the physical channel resources piece that logic channel tree fundamental node 0 shines upon in 1 to 10 frame is respectively 6,1,2,4,8,5,10,9,7,3.The number of times of the same physical channel resources piece that these two logic channel tree fundamental nodes that belong to different accurate orthogonal modes lower channel subtrees respectively are mapped to for once promptly all has been mapped to physical channel resources piece 6 when the 1st frame.And, by comparison sheet 1 and table 2, be not difficult to find that any one logic channel tree fundamental node is set fundamental node with another identical logic channel and taken the number of times of same physical channel resources piece smaller or equal to 1.Therefore, the interference between the different layers in the accurate quadrature backward channel of equalization effectively.
Second execution mode of the present invention relates to channel resource block mapping method, second execution mode and first execution mode are roughly the same, its difference only is, in the first embodiment, terminal with Reed-Solomon sign indicating number sequence as corresponding to the logic channel tree fundamental node of the accurate quadrature reverse link of this terminal mapping mode to the physical channel resources piece, and in the present embodiment, terminal with the Reed-Solomon sign indicating number sequence of expansion as the mapping mode that arrives the physical channel resources piece corresponding to the logic channel tree fundamental node of the accurate quadrature reverse link of this terminal.
Specifically, terminal adopts improved RS sign indicating number, make cycle of calling sequence increase for q-1 square, promptly pass through multinomial

The lower bound integer of i is got in expression, and m represents to be mapped to the time slot of physical channel resources piece, and f (m) is illustrated in the physical channel resources piece number of time slot m mapping.
Since the cycle of the sequence that terminal generates increase for q-1 square, therefore comprised the mapping of the physical channel resources piece of more a plurality of time slots, that is to say, square time slot every q-1, the Reed-Solomon sign indicating number sequence conduct that terminal just needs to generate expansion is once more set the mapping mode of fundamental node to the physical channel resources piece corresponding to the logic channel of the accurate quadrature reverse link of this terminal, thereby further reduced the complexity of terminal modulating data to the Resource Block, and made that the application of this programme is more flexible.
The 3rd execution mode of the present invention relates to channel resource block mapping method, and the 3rd execution mode is done further improvement on the basis of second execution mode.In second execution mode, terminal adopts improved Reed-Solomon sign indicating number sequence, make cycle of calling sequence increase for q-1 square, and in the present embodiment, terminal is further introduced parameters R LSectorHopSeed, so that the mapping mode in the different districts to be set.
Specifically, terminal is passed through multinomial

In having the cellular communication system of a plurality of base stations, consider the interference between the equalization different districts, can control mapping mode between the neighbor cell by parameters R LSectorHopSeed.If RLSectorHopSeed is identical, then the mapping mode between the sub-district is identical, if RLSectorHopSeed difference, then the mapping mode difference between the sub-district.Situation to grand diversity can be got identical mapping mode, if get the different mappings mode then the further interference between the different layers in the accurate quadrature backward channel of equalization.
The 4th execution mode of the present invention relates to channel resource block mapping method, and the 4th execution mode is done further improvement on the basis of the 3rd execution mode.In the 3rd execution mode, terminal adopts improved Reed-Solomon sign indicating number sequence, make cycle of calling sequence increase for q-1 square, and introduce parameters R LSectorHopSeed mapping mode in the different districts be set.But owing to have protection subcarrier or protection physical channel resources piece usually in ofdm system, therefore, in the present embodiment, terminal needs further to introduce B parameter

Pass through formula
Generation is as the sequence of logic channel tree fundamental node to the mapping mode of physical channel resources piece, can be so that present embodiment be supported various bandwidth, and for example, comprise 5,000,000 bandwidth of a carrier wave and comprise 20,000,000 bandwidth etc. of 4 carrier waves.And, by at different frames, modulate data on the physical channel resources piece of different carrier, for example, the label that modulates data on the 1st carrier wave in the 1st frame is on 5 the physical channel resources piece, the label that modulates data on the 3rd carrier wave in the 2nd frame is on 8 the physical channel resources piece, can further reduce the situation that terminal and identical other-end take same physical channel resources piece, the interference between the different layers in the accurate quadrature backward channel of equalization better.
The 6th execution mode of the present invention relates to channel resource block mapping method, and present embodiment has been done further improvement on first execution mode.When calculating the f (m) of time slot m, adopt alternative manner, utilize the intermediate variable of a time slot m to calculate the f (m+1) of next time slot m+1.
For example, be located at the m time slot, establish f
0(m)=c * 2
m, the f of Ji Suaning (m)=c * 2 then
m+ c
0Can be converted to f (m)=f
0(m)+c

0(m+1)+c
0=f
0(m) * 2+c
0, c
0∈ GF (p).This shows, when calculating the f (m) of each time slot, only need do a multiplication and an add operation, further reduced operand.
Similarly, for
Calculating, suppose I (m)=c * α
m, I (m+1) can iterative computation be so: I (m+1)=α * I (m), and f (m+1) may be calculated:
For
Calculating, suppose I (m)=(4 * RLSectorHopSeed+c) * α
m, I (m+1) can iterative computation be so: I (m+1)=α * I (m), and f (m+1) may be calculated:
For
Calculating, suppose I (m)=(4 * RLSectorHopSeed+c) * α
m, I (m+1) can iterative computation be so: I (m+1)=α * I (m), and f (m+1) may be calculated:
The 7th execution mode of the present invention relates to channel resource block mapping method, roughly the same with first execution mode, its difference only is, in the first embodiment, number corresponding to the logic channel tree fundamental node of the accurate quadrature reverse link of each terminal is a power of prime, and in the present embodiment, be not power of prime corresponding to the number N1 of the logic channel tree fundamental node of the accurate quadrature reverse link of each terminal, therefore the f (m) of the time slot m that calculates also will do corresponding adjustment.
Specifically, when the number N1 corresponding to the logic channel tree fundamental node of the accurate quadrature reverse link of each terminal is not power of prime, can choose the nearest power of prime N2 greater than N1, N2＞N1 gets different c according to the Reed-Solomon sign indicating number
0Generate the capable sequence of N2.In order to obtain the mapping mode of N1 logic channel tree fundamental node, need carry out deletion action to the number that surpasses N1-1 in each column-generation sequence, this is counted in the column, and line index moves on successively greater than these several elements of being expert at, to fill up the vacancy of this number after deleted.That is to say, for each time slot m, if the physical channel resources piece f (m) that is mapped to greater than N1-1, then with this f (m) deletion, each f (m) that the line index in this f (m) column is expert at greater than this f (m) moves on successively.
