Description

Method for indicating telecommunication system resources, system and dispensing device and receiving system

Technical field

The present invention relates to the communication resource distribution technology, refer to a kind of method for indicating telecommunication system resources, system and dispensing device and reception especially.

Background technology

Insert in (E-UTRA, EvolvedUniversal Terrestrial Radio Access) system at third generation cooperative programme (3GPP) evolution global radio, frequency domain dispatching is a key character.Such as, if system transmission bandwidth is divided into the Resource Block (RB that a plurality of continuous subcarriers are formed, ResourceBlock), so, UE measures the channel quality of each RB and reports the base station by signaling, UE is distributed to according to the dispatching algorithm RB that channel quality is good in the base station, realizes frequency domain dispatching.In order to save the signaling amount that channel quality reports, the channel quality parameter that UE can a top-quality several RB of reporting channel, and command transmitting indicates the channel quality of which RB to be reported, and the signaling of this transmission is resource indication signaling.

In addition, in 3GPP E-UTRA systems technology research report TR25.814, with single carrier frequency division multiplexing (SC-FDMA) as the uplink multi-address transmission technology.In the system based on the SC-FDMA technology, the RB that the running time-frequency resource of distribution is formed with a plurality of continuous sub-carriers usually is as elementary cell.In order to reduce the peak-to-average force ratio of multi-carrier transmission, the resource of distributing to each user is the continuous RB of one or more frequency domains, as shown in Figure 1, Fig. 1 is that telecommunication system resources distributes schematic diagram, two continuous RB1 and RB2 distribute to user terminal 1 (UE_1), five continuous RB3～RB7 distribute to UE_2, and a RB8 distributes to UE_3, and four continuous RB9～RB12 distribute to UE_4.

In system based on the SC-FDMA technology, the base station is by sending the current resource allocation conditions of resource allocation control signaled UE, in the resource allocation control command, comprise the sign (ID) of the UE that is scheduled for, and the resource allocation information that is used to transmit data is a resource indication signaling.All UE can receive and demodulation resource distribution control signaling in the sub-district, to know self current whether being scheduled for, if be dispatched to, know that by resource indication signaling the base station is the resource location that self distributes.

Usually, the coded system of resource allocation control signaling has two kinds: the resource allocation control signaling of each UE is carried out absolute coding; The resource allocation control signaling of a plurality of UE is carried out combined coding.Wherein, combined coding can increase the length of encoding block, improves coding gain.

Under resource allocation control signaling combined coding mode, if it is continuous distributing to the Resource Block of each scheduling UE, then only need ID with the current UE that is scheduled, inform UE with the initial RB of the continuous resource piece that distributes for the UE that respectively is scheduled or the sign of end RB, the UE that is dispatched to just can be defined as the position of the RB of its distribution, promptly indicates as sign initial or the ending resource piece by resource indication signaling.In conjunction with Fig. 1, draw resource indication signaling easily according to the bitmap method and be: 101000011000, indicated the state of each Resource Block by this resource indication signaling.

Above-mentioned channel quality reports with resource allocation and is carrying out resource when indication, and a kind of method relatively more commonly used is bitmap method (bitmap).Suppose to have N RB, each RB sign is respectively RB1, RB2 ... RBN, N are positive integer, and the sequence that resource indication signaling adopts the N bit to form is indicated the sign of the RB that needs indication.For example, if i Resource Block need be instructed to, then the value of the sequence bit of corresponding RBi is set to 1 in the resource indication signaling, and the value of other sequence bit is set to 0.

Concrete indicating means is as shown in table 1, table 1 is bitmap indication signal, suppose that RB1, RB5, RB6 and RB10 are the RB that is instructed to, then the sequence bit of corresponding RB1, RB5, RB6 and RB10 can be set to 1 in the resource indication signaling, the value of other sequence bit then is set to 0 and gets final product, this resource indication signaling is: 100011000100, indicated the state of each Resource Block by this resource indication signaling.

Table 1

Again for example, resource allocation conditions shown in Figure 1 draws resource indication signaling easily according to the bitmap method and is: 101000011000, indicated the sign of each initial Resource Block by this resource indication signaling.

The bitmap method is a kind of resource indicating method more intuitively, carries out the mapping of RB sign to resource indication signaling at transmitting terminal; At receiving terminal, corresponding according to each sequence bit in RB sign in the resource indication signaling and the resource indication signaling separated and maps out RB and identify and get final product.Find out that easily because the figure place of resource indication signaling is identical with the number of RB, the signaling amount expense that causes the bitmap method to need is bigger.

The resource indication signaling generation module, reception is provided with the indicator sequence of module from indicator sequence, according to the value of a certain specific bit in advance in the indicator sequence, and give up described specific bit in advance, obtain resource indication signaling and the output formed by (N-1) position binary sequence.

Telecommunication system resources indication receiving system comprises:

The resource indication signaling parsing module, be used to receive resource indication signaling from the resource indication signaling generation module generation of opposite end, the value of determining the specific bit given up in the indicator sequence according to this resource indication signaling obtains indicator sequence, and sends to Resource Block sign determination module.

Indexed resource piece determination module receives the indicator sequence from the resource indication signaling parsing module, parses the Resource Block sign that is instructed to.

Need to prove that described telecommunication system resources indication dispensing device and telecommunication system resources indication receiving system can be independent entity.

Fig. 3 is the flow chart of resource indicating method of the present invention, and this method may further comprise the steps:

Exist in step 300:N the Resource Block need be instructed to, the indicator sequence of being made up of the N bit is set less than N/2 Resource Block.

Suppose that transmission bandwidth is divided into N Resource Block, need the sign of indication k Resource Block wherein, and $1\&le;k<\frac{N}{2}.$

At transmitting terminal, the sign of each Resource Block in N the Resource Block is set, the sign of Resource Block is corresponding one by one with the position in the indicator sequence, with N position binary system indicator sequence { b _p} _P=1 ^NRepresent whether k Resource Block is instructed to b _p∈ 0,1}, b _NBe highest order, preestablish b _pA certain value in the span is an indicated value as 0 or 1, and another value is non-indicated value as 1 or 0.In the indicator sequence of N position, be set to indicated value with the corresponding position of sign of the Resource Block of needs indications, other position all is set to non-indicated value.If in N the Resource Block, p ₁, p ₂..., p _kThe Resource Block of individual Resource Block for needing to indicate, wherein, 1≤p _k＜p _K-1＜p ₁≤ N, then indicator sequence { b _p} _P=1 ^NIn p ₁, p ₂..., p _kThe value of position is an indicated value.This shows the Resource Block sign and the indicator sequence { b that will indicate _p} _P=1 ^NBe one to one.

Step 301:, obtain the resource indication signaling of forming by (N-1) position binary sequence, with the indexed resource piece according to the value of any specific bit in the indicator sequence.

Specify indicator sequence { b in advance _p} _P=1 ^NIn a certain position b _i, according to b _iValue, formation sequence { c _p} _P=1 ^N: definition b _iA certain value in the span is default decision content as 1 or 0, works as b _iWhen equaling to preset decision content, sequence { c _p} _P=1 ^NEqual sequence { b _p} _P=1 ^NWork as b _iEqual in the span default non-decision content as 0 or at 1 o'clock, sequence { c _p} _P=1 ^NEqual sequence { b _p} _P=1 ^NMiddle indicated value becomes non-indicated value, and non-indicated value becomes the sequence that generates after the indicated value.Can be described below with formula (1) and (1 '):

When default value is 0,

$c_p=\left\{\begin{array}{c}{b}_p,b_i=0\\ (1-b_p),b_i=1\end{array}\right.---\left(1\right)$

When default value is 1,

$c_p=\left\{\begin{array}{c}{b}_p,b_i=1\\ (1-b_p),b_i=0\end{array}\right.---(1\text{'})$

Remove sequence { c _p} _P=1 ^NIn c _iThe position is a specific bit, generates resource indicator sequence { d _p} _P=1 ^N-1, can be described below with formula (2):

$d_p=\left\{\begin{array}{c}{c}_p,1\&le;p<i\\ c_{p+1},i\&le;p\&le;N-1\end{array}\right.---\left(2\right)$

Because $k<\frac{N}{2},$ Therefore, sequence { b _p} _P=1 ^NIn indicated value number must less than

But not the number of indicated value necessarily more than or equal to

Sequence { the c that is generating _p} _P=1 ^NIn, work as b _iWhen equaling default value, the number of indication less than

Work as b _iWhen being not equal to default value, the number of indicated value then more than or equal to

Can learn according to this relation:

(1) different resource block identification indicator sequence { b _p} _P=1 ^NCorresponding sequence { the c that generates _p} _P=1 ^NDifference, i.e. sequence { c _p} _P=1 ^NIdentifying with Resource Block is one to one.

(2) sequence { c _p} _P=1 ^NIn, the number of indicated value and b _iValue be correlated with, therefore, remove sequence { c _p} _P=1 ^NIn corresponding position c _i, the sequence { d of generation _p} _P=1 ^N-1With resource identification is corresponding one by one.Therefore, the Resource Block sign can be mapped as the sequence { d of N-1 position _p} _P=1 ^N-1, and with sequence { d _p} _P=1 ^N-1As resource indication signaling.

The inventive method further comprises:

At receiving terminal, receive resource indication signaling { d _p} _P=1 ^N-1After, at first judge { d _p} _P=1 ^N-1In the number of indicated value, if the number of indicated value less than Then at sequence { d _p} _P=1 ^N-1In insert default value between i-1 and the i position, obtain sequence { b _p} _P=1 ^NIf the number of indicated value is not less than

Then earlier with sequence { d _p} _P=1 ^N-1In indicated value change to non-indicated value, non-indicated value changes to indicated value, the sequence { d after will changing again _p} _P=1 ^N-1In insert another value beyond the default value in the span between i-1 and the i position, obtain sequence { b _p} _P=1 ^NAgain according to sequence { b _p} _P=1 ^NThe position of middle indicated value determines that the Resource Block that indicates identifies.

As seen, when utilizing this method to carry out the resource indication, do not need to carry out any complex mathematical computing, thereby realized of the fast mapping reconciliation mapping of Resource Block sign with resource indication signaling.

Especially, some or a plurality of Resource Block signs of choosing are that receiving terminal is known in the Resource Block of system divides, then utilize the Resource Block of above-mentioned resource indicating method indication except that these Resource Block to get final product.For example, when carrying out the resource allocation indication, if indication is that initial Resource Block sign and the resource allocation of distributing to the resource of UE always begins with first Resource Block, perhaps indication is that the ending resource block identification of resource and the resource allocation of distributing to UE always finishes with last Resource Block, and then resource indication signaling only need indicate in N-1 the Resource Block the individual initial or ending resource block identification of k-1 and gets final product.At this moment, still adopt the described resource indicating method of Fig. 2, only need with N-1 bit { b _p} _P=1 ^N-1Represent resource allocation conditions, the value of having only the k-1 position in the N-1 position is an indicated value, and other all is non-indicated value, adopts said method equally, generates N-2 bit sequence { d at last _p} _P=1 ^N-2As resource indication signaling.And at this moment, the number k of the Resource Block that need indicate should satisfy $(k-1)<\frac{(N-1)}{2},$ Promptly $k<\frac{(N+1)}{2}.$

With in the system based on the SC-FDMA technology, the base station is an example by sending the current resource allocation conditions of resource allocation control signaled UE, specifically describes the implementation procedure of the inventive method below:

Suppose that the transmission bandwidth of system is 5MHz, evenly be divided into N=12 Resource Block, distribute to k=4 scheduling UE, be assumed to be UE_1, UE_2, UE_3 and UE_4; And the Resource Block of distributing to each UE is that frequency domain is continuous, and resource allocation conditions is as shown in table 3, and table 3 shows the initial Resource Block sign of the resource of utilizing the resource indication signaling indication to distribute to each UE.

Table 3

Here, preestablishing indicated value is 1, and non-indicated value is 0.

As shown in table 3, initial Resource Block sign is expressed as with 12 bit indicator sequences:

${\left\{b_p\right\}}_{p=1}^{12}=\left\{101000011000\right\}$

Continuous RB1～RB2 distributes to UE_3, and continuous RB3～RB7 distributes to UE_2, and RB8 distributes to UE_1, and continuous RB9～RB12 distributes to UE_4.

Suppose that most significant bits is in rightmost, wherein, 1 pair of sign in requisition for the RB of indication of indicated value is respectively RB1, RB3, RB8 and RB9.

Suppose to preestablish according to indicator sequence { b _p} _P=1 ¹²In the 1st value generate resource indication signaling, and the default value of definition is 0, has

$c_p=\left\{\begin{array}{c}{b}_p,b_i=0\\ (1-b_p),b_i=1\end{array}\right.$

Then, because b ₁=1, sequence then ${\left\{c_p\right\}}_{p=1}^{12}=\left\{0140111100111\right\},$ At this moment, most significant bits is in rightmost.With c ₁Remove, obtain sequence ${\left\{d_p\right\}}_{p=1}^{11}=\left\{10111100111\right\},$ And should { d _p} _P=1 ¹¹As the resource allocation indication signaling.

At receiving terminal, after UE receives the resource allocation indication signaling, determine the resource allocation conditions of signaling indication by separating mapping, the specific implementation process is:

Determine { d _p} _P=1 ¹¹The number of middle indicated value 1 is 8, greater than $\frac{N}{2}=6$ , therefore, can determine c _p=1-b _p, and b ₁=1, thus sequence obtained ${\left\{b_p\right\}}_{p=1}^{12}=\left\{101000011000\right\}.$ This sequence { b _p} _P=1 ¹²In the Resource Block corresponding with indicated value 1 be initial Resource Block.

Compare with the bitmap scheme, this programme makes resource allocation indication signaling expense save 1 bit, has reduced the signaling amount expense, has saved system resource.Simultaneously, realized of the fast mapping reconciliation mapping of Resource Block sign at receiving terminal with resource indication signaling.

The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
